What powder materials are used in Yuanlei small class | floor paint and what effect does powder materials play in application?

 

There are a lot of people ask me what is floor paint?

Hear this word may feel very strange

But in fact, in our daily life, everyone has seen it

Even almost every day you will walk through the ground with floor paint,

that floor paint in the end is what?

 

 

The above picture is a super floor customized for Foshan MVP arena.

Elastic Silicon PU Stadium 」

Such floor paint is not to break the consistent cognitive, creative!

If Xiao Bian could play basketball in such a court when he was young, he would win MVP in every court!

So back to the point, what is the floor paint?

 

 

Actually floor paintmainly

made of oil, tree, color, solvent, etc,

with bright, real,Beautiful, wear-resistant, waterproof, anti-corrosion and other characteristics,

We usually seeSports ground, factory, parking lot, warehouse, shopping mallAnd so on the ground,

are painted with floor paint,

Now floor paint not only in the project decoration will see,

Even began to enter the home decoration industry!

 

 

Then someone askedFloor paintWhat's the difference with paint?

Floor paint is a semi-finished product, in addition to the characteristics of the paint itself

also hasImpact resistance, weight resistance, abrasion resistance, no discoloration, environmental protectionSuch as paint is not the same characteristics;

And now the type of floor paint is divided into many kinds,

Can be customized according to different industrial environment,

Such as thin layer coating, thick slurry type self leveling, anti slip coating, bearing type mortar floor, anti-static, anti-corrosion floor, etc

 

 

Floor paint spraying is difficult and has a long cycle. You must find a professional team!

 

After the above introduction, for floor paint, I believe we already have a certain understanding. It is an important industrial coating paint, the use of the scope from industrial plants, corridors, large parking lots to have special requirements of anti-static, fire flower, chemical corrosion, nuclear radiation floor, etc., widely used in many areas of production and life, the floor to protect, bright, beautiful, beautiful, wear-resistant, waterproof, anti-corrosion, anti-static and other functions. In addition to the main components of the floor paint inside the resin, there is a considerable part of the filler, this part of the filler mainly to improve or improve the performance of the floor paint, but also an indispensable part.

barium sulfate

It has two kinds of natural and synthetic, the natural product is called barite powder, and the synthetic product is called precipitated barium sulfate.Natural products are mainly used for floor coatings in the primer, because it has low oil absorption, less base material consumption, can be made into thick film primer, can also be mixed with other pigment base material, its filling performance, leveling, impermeability are better, can increase the film thickness and wear resistance, the disadvantage is that the density of the coating is easy to precipitate.Synthetic barium sulfate has better performance, high whiteness and fine texture.Barium sulfate has good acid resistance and can be used as a filler for acid resistant floor coatings.

 

silicon powder

Microcrystalline structure, spherical powder, good leveling, high hardness, impact resistance, high weather resistance. Used for all kinds of floor coatings (polyurethane/epoxy type general, oily/water-based general).

Functional advantages:

1. Improve the hardness of the paint film, wear resistance and scratch resistance, impact resistance, and improve the life of the paint;

2, low oil absorption, good filling, good leveling, reduce costs;

3. High temperature resistance, cold and heat shock resistance, water resistance, acid and alkali resistance, yellowing resistance, ultraviolet resistance, and good aging resistance;

4, low expansion coefficient, good electrical insulation performance, anti-static;

5, good transparency, improve the fullness and brightness of the primer pigment hair color;

 

6. Good compatibility: easy to combine with epoxy resin, polyurethane, etc., water-based and oil-based

 

Talcum powder

1. Increase the amount of filler without significantly increasing the viscosity of the coating, and the talc powder has good fluidity to ensure the leveling of the coating during construction;

2. The addition of unique flake geometry powder can significantly reduce the linear shrinkage of the coating film;

3. High whiteness, easy color matching, high comprehensive cost performance;

4. Contains silicon dioxide, which can improve the wear resistance of the coating;

5. Stable chemical properties, does not affect the coating chemical resistance and other comprehensive properties;

 

6. with resin and other materials can be very good compatibility.

 

Calcium carbonate

Calcium carbonate is an inorganic compound, the chemical formula isCaCO3, with a relative molecular weight of 100.9 and CAS number of 471-34-1, is a common substance on the earth and is the main component of natural minerals such as marble, limestone, chalk and rock.Calcium carbonate powder is white powder, odorless and tasteless, melting point 1339 ℃, stable in the air, almost insoluble in water, containing ammonium salt or ferric oxide in the water dissolved, insoluble in alcohol, dilute acetic acid, dilute hydrochloric acid, dilute nitric acid bubble, and dissolved, heated to 898.6 ℃ began to decompose and calcium oxide and carbon dioxide.

 

Calcium carbonate powder is widely used in plastics, rubber, coatings and other industries as filling materials, which can not only improve the rigidity, hardness, wear resistance, heat resistance and dimensional stability of composite materials, but also reduce the cost of products. DueCaCO3 has a wide range of raw materials, low price and non-toxicity, so it is the largest amount of inorganic filler in polymer composite materials. However, there are two defects in the direct use of calcium carbonate in polymers:(1) intermolecular force, electrostatic interaction, hydrogen bond, oxygen bridge, etc. will cause the agglomeration of calcium carbonate powder;(2) The surface of calcium carbonate has strong hydrophilic and alkaline hydroxyl groups, which will make its affinity with polymers worse, uneven dispersion in the polymer, resulting in defects in the interface between the two materials. In order to enhance the wettability of CaCO3 in high polymer, eliminate the high surface potential energy, improve its dispersion performance and hydrophobic lipophilicity in composite materials, improve the processing and mechanical properties of CaCO3 filled composite materials, and increase its filling amount in composite materials, it is very necessary to modify the surface of CaCO3.

 

 

 

Mica powder

 

Mica powder is a fine powder made of mica ore after grinding. It is a complex silicate mineral, and there are many kinds of it. Often used in coatings are mainly muscovite and phlogopite. Mica powder can reduce the penetration of water in the coating film, improve the weather resistance and corrosion resistance of the coating film, have good flexibility and mechanical strength, have good heat resistance, have good chemical stability, and have good UV resistance and hiding power.

 

 

 

anti-settling agent

 

Fumed silica is prepared by hydrolysis of silicon tetrachloride in a hydrogen-oxygen flame. It has a small particle size, a large specific surface area, and a silanol group on the surface. These silanol groups can interact with adjacent fumed silica particles to form hydrogen bonds, which form a contact deformation structure! Fumed silica is an ideal anti-settling agent that is very effective in preventing the precipitation of pigments in coating systems. Especially for the color paste system, the appropriate amount of addition will greatly improve the stability of the color paste, and can reduce the amount of wetting and dispersing agent, in order to improve the applicability of the color paste and reduce the color paste on the coating system. The precipitation of fumed silica is very beneficial to the storage of coatings, especially some pigments such as metal powder and flakes, which are very easy to settle and cannot be completely suspended. The use of fumed silica can ensure its dispersion without precipitation. In completely non-polar liquids, such as hydrocarbons and halogenated hydrocarbon solvents without bonding ability, the viscosity recovery time is only a fraction of a second. In polar liquids, such as amines, alcohol rice, antelope, aldehydes and glycols with hydrogen bonding, the recovery time is as long as several months, which depends on the concentration of fumed silica and its dispersion degree. fumed silica is pre-dispersed and added to the finished paint, in order to improve its dispersion quality, high-speed dispersing machine or three-roll machine is usually used. If the dispersion is not sufficient, the paint film will have particles, which will affect the gloss. It has been reported in the literature that fumed silica is added as an anti-settling agent to a copper-acrylic resin conductive coating. Tests have proved that fumed silica can make thermoplastic acrylic resin produce thixotropy and prevent the settlement of filler particles, but the addition amount is too much, the coating becomes a gel state, and the conductivity of the coating decreases.

Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.
