1. Main base material (1) polyurethane resin: it is made of isocyanate and polyester, polyether, epoxy resin, castor oil or its processed products (oxidized polymer glycerol alcoholate), hydroxy containing thermoplastic polymers (such as polyacrylate resin containing B-hydroxyethyl, hydroxy containing chloroacetic acid copolymer resin), cellulose acetate butyrate and other formulations to produce many kinds of polyurethane coatings. For example, TDI or MDI used with polyether is the main base material of elastic floor coating; HDI is used together with polyacrylic acid resin containing B hydroxyethyl, which is the base material of high-grade floor coatings. (2) Epoxy resin: when the epoxy resin is used for floor coating, the seamless floor coating material is used for the epoxy resin on the floor, and the main base material of the water emulsion exterior wall coating. 2. Secondary film-forming material Secondary film-forming material is also an important part of the film, but it cannot form a film without the main film-forming material. This ingredient is the pigment used in the paint. Adding pigment to the coating can not only improve the film performance, but also increase the variety of coating. 3. Auxiliary film-forming substances Auxiliary film-forming substances cannot form the film or are not the main body of the film, but they have a great impact on the film forming process (construction process) of the paint, or play some auxiliary role in the performance of the film (2) Auxiliary materials: With film forming substances, pigments and solvents form the paint, but generally in order to improve the performance, some auxiliary materials are often used, There are many auxiliary materials used in the coating, each with its own specialty, but the amount is very small, usually a few percent to a few thousandths or less. The dosage is small, but the effect is significant. According to the function of auxiliary materials, it can be divided into drying agent, plasticizer, wetting agent, ultraviolet absorber, etc. Drier and plasticizer are used in large quantities. The following is a description of the types, composition, characteristics or uses of floor paint.
1. Epoxy floor paint is usually composed of epoxy resin, solvent, curing agent, pigment and additives. This kind of paint includes many kinds of floor paint, 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 feature is its strong adhesion to the cement base, It can resist water and other corrosive media, and has very good physical and mechanical properties of the coating film. It is suitable for various factories, repair yards, courts, parking lots, warehouses, shopping malls and other ground places. 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 and good adaptability of concrete base. The high bond strength with the concrete base surface can effectively resist the back pressure caused by water vapor. It is suitable for sealing primer of putty, masonry and concrete structures, as well as sealing of thermal zinc spraying, aluminum spraying and inorganic zinc rich coating. 2. The polyurethane floor paint is composed of polyether resin, polyether resin, acrylate resin or epoxy resin. Because the film hardness and adhesion with the base layer are inferior to those of epoxy resin coatings, the variety of polyurethane floor paint is less. Mainly used in places with elastic floor paint and anti-skid floor paint. 3. Anticorrosive floor paint: in addition to various strength properties of loadable floor paint, it can also withstand the corrosion of various corrosive media. It is suitable for the coating of various chemical plants, kerosene plants, sanitary materials plants and other floors. 4. Elastic floor paint is made of elastic polyurethane, and the film has walking comfort due to its elasticity. It is suitable for ground painting in various sports places, public places and some factories and workshops. 5. Antistatic floor paint can discharge static charges, prevent accidents due to static accumulation, shield electromagnetic interference and prevent dust adsorption, etc. It can be used for various floor coatings requiring anti-static. It is suitable for power plant, electronic factory workshop, initiating explosive device factory, microcomputer room, etc. 6. The anti slip floor paint film has high friction coefficient and anti slip performance. It is used for various floor coatings with anti slip requirements. It is a kind of good floor paint in rapid application and development stage. It is used for ground coating with anti-skid requirements. 7. The loadable floor paint has high bonding strength, tensile strength and hardness with the concrete base, and has good impact resistance, bearing capacity and wear resistance. It is suitable for painting floors of factories, workshops and warehouses where heavy vehicles and forklifts are needed.
