What is floor paint
Floor paint was first invented by Germany in 1934, mainly made of oil, tree material, color, solvent, etc., mainly divided into decorative floor paint, heavy corrosion floor paint, heavy duty floor paint, etc. Floor paint by a variety of different substances by mixing, dissolving, dispersing and many other road production process manufacturing and composition. Floor paint is bright, real, beautiful, wear-resistant, waterproof, anti-corrosion and other characteristics.
Features of floor paint
① Good adhesion and physical and mechanical properties: Strong adhesion to steel substrates or other coated objects is a prerequisite for obtaining high-quality heavy-duty anti-corrosion coatings, especially wet film adhesion, and low shrinkage, Appropriate hardness, toughness, wear resistance, temperature resistance, etc.
②Good corrosion resistance: including corrosion resistance to chemical atmosphere, water, acid, alkali, salt, other solvents, etc.
③ have good resistance to the permeability of the medium: the excellent shielding effect of heavy-duty anti-corrosion coating, after the film is required, the coating has as low as possible the permeability of water and oxygen and other corrosion factors.
4 have good construction performance: the coating to achieve the appropriate thickness (the thicker the coating, the better the shielding effect) and structural design requirements.
Types and characteristics of floor paint
It is usually composed of epoxy resin, solvent, curing agent, pigment and auxiliary agent. This kind of coating contains many floor paint varieties, such as solvent-free self-leveling floor paint, anti-corrosion floor paint, wear-resistant floor paint, anti-static floor paint and water-based floor paint. Its main characteristics are strong adhesion with cement base layer, water resistance and other corrosive media, and very good physical and mechanical properties of coating film. Adapt to all kinds of factories, repair field, stadium, parking lot, warehouse, shopping malls and other ground places. A two-component epoxy sealing varnish composed of epoxy resin, modified curing agent, solvent, etc. The concrete base surface has high permeability, which greatly improves the strength of the concrete base surface. Excellent alkali resistance, good adaptability of concrete base surface. The high bond strength with the concrete base surface can effectively resist the back pressure caused by water vapor. It is suitable for the sealing primer of putty, masonry and concrete structure, and can also be used as the sealing of thermal spraying zinc and aluminum spraying and the sealing of inorganic zinc rich coating.
Corrosion protectionEtching floor paint
In addition to having a load of floor paint a variety of strength properties, but also able to withstand a variety of corrosive media corrosion. Adapt to a variety of chemical plants, kerosene plants, sanitary materials plants and other ground coating.
Made of elastic polyurethane, the coating film has walking comfort due to its elasticity. Adapt to all kinds of sports venues, public places and some factory floor painting.
With polyether resin, polyether resin, acrylate resin or epoxy resin as a component, due to the hardness of the coating film and the adhesion with the base is not as good as epoxy resin coatings, its varieties are less. Mainly used for elastic floor paint and non slip floor paint places.
It can discharge electrostatic charge, prevent accidents caused by electrostatic accumulation, and shield electromagnetic interference and prevent dust adsorption. It can be used for various anti-static ground coatings. Adapt to the power plant, electronics factory workshop, fire products factory, computer room, etc.
The coating film has a high coefficient of friction and anti-skid performance. It is used for various ground coating with anti-skid requirements. It is a kind of good ping paint that is in the stage of rapid application and development. For a variety of anti-skid requirements of the ground coating.
This kind of floor paint and concrete base of high bond strength, tensile strength and hardness are high, and has good impact resistance, bearing capacity and wear resistance. Adapt to the need for heavy vehicles and forklifts to walk the factory workshop and warehouse floor coating.
Why is the floor paint specially separated from the middle coat?
Epoxy floor paint is a viscous liquid material, to construction on the ground to protect the role of concrete, you need two coatings:
1, the primer layer, this is to close the gap of concrete, to prevent the underground water vapor, air, corrosive substances floating on the epoxy floor damage.
2, the topcoat layer, the coating directly facing the user, on the one hand, it needs to be able to resist people walking, mechanical friction, on the other hand, it also needs to be able to isolate the existence of corrosive substances from the upper layer into the interior of the epoxy floor paint.
After reading the introduction of primer layer and surface paint layer, is there any doubt, why should there be a special intermediate floor paint material?
The reasons are as follows:
1. Enhance wear resistance.Epoxy floor paint is cured film floor paint, it is through the formation of protective coating on the surface of concrete to complete its mission of protection, like our skin. But because it is a film, it can be worn. The thinner the floor paint project, the more easily worn out. The coating is sandwiched in the middle of the primer and finish, improve the wear resistance and service life of epoxy floor engineering key.
2. Increase the thickness.General floor paint primer and topcoat construction, will only produce 0.2-0.5mm coating, so not only wear is very poor, back to the people walk in the above experience is very poor. This everyone should have feelings, thick epoxy floor project has a certain degree of flexibility, walking on the top is very comfortable, fell down will not hurt.
3. Reduce costs.Since the coating does not need to undertake the task of protecting various harmful substances, the requirements for it can actually be reduced a little. And the coating is in the middle of the epoxy floor coating, colorful no one can see, the toner can be saved. Therefore, the middle coat is generally cheaper than the top coat and primer.
Floor paint coating matters needing attention
Before the construction of floor paint, it is important to understand the safety regulations of the product. For example, Jin Zhaohui acrylic engineering primer and Jin Zhaohui acrylic engineering topcoat, although there is only one word difference and their functions are similar, they need to be paid attention to in proportion and use. In case of accidents, they will endanger human health.
