In the choice of ground coatings, people pay attention to functional ground construction materials, in addition to safety and environmental protection is also very important. Especially in some green enterprises and family construction is particularly prominent. So do these customers care about the toxicity of epoxy floor paint? Is it safe or environmentally friendly? Here we will introduce the composition of epoxy floor paint material. 环氧地坪漆(epoxy flooring)，主要成分为环氧树脂和固化剂。环氧地坪漆可分为溶剂型和无溶剂型2种，溶剂型环氧地坪涂料在生产、施工和固化过程中会排放一定量的挥发性有机物(VOC)，但成本比较低；而无溶剂环氧地坪涂料符合环保理念。
Epoxy floor paint (epoxy flooring), mainly composed of epoxy resin and curing agent. Epoxy floor coatings can be divided into solvent-based and solvent-free. Solvent-based epoxy floor coatings emit a certain amount of volatile organic compounds (VOC) in the process of production, construction and curing, but the cost is relatively low. Solvent-free epoxy floor coatings conform to the concept of environmental protection.
Epoxy floor paint is made up of many different materials, which are mixed, dissolved and dispersed. According to the different functions of each component of floor paint, it can generally be divided into main film-forming substance, secondary film-forming substance and auxiliary film-forming substance.
The main base material of epoxy floor paint in China is synthetic resin.
（1）聚氨脂树脂：它是由异氰酸酯与聚酯,聚醚，环氧树脂，蓖麻油或其加工产品（氧化聚合物 甘油醇解物）含羟基的热塑性高聚物（如含 B-羟乙基的聚丙烯酸酯树脂，含羟基的氯醋共聚树脂）醋酸丁酸纤维素等配方，制成许多品种的聚氨酯涂料。如 TDI 或 MDI 与聚醚配用是弹性地面涂层的主要基料；HDI 与含B 羟乙基的聚丙烯酸树酯配用，是高档地坪涂料的基料。
(1) Polyurethane resin: It is made of isocyanate and polyester, polyether, epoxy resin, castor oil or its processed products (oxidized polymer glycerol hydrolysate), thermoplastic polymer containing hydroxyl group (such as polyacrylate resin containing B-hydroxyethyl group, chloroacetic copolymer resin containing hydroxyl group), cellulose acetate butyrate, etc. A variety of polyurethane coatings. For example, TDI or MDI with polyether is the main base material of elastic floor coatings; HDI with polyacrylic acid resin containing B hydroxyethyl group is the base material of high-grade floor coatings.
(2) Epoxy resin: When epoxy resin is used for floor coatings, low molecular weight polyamide resin is often used for curing. At present, epoxy resin is used for seamless floor coatings and the main base material of water-emulsion exterior wall coatings.
Secondary film-forming material:
Secondary film forming material is also an important part of the film, but it can not be separated from the main film forming material to form a film. This component is the pigment used in the paint. Adding pigments to coatings can not only improve the performance of coatings, but also increase the variety of coatings.
Auxiliary film forming material:
Auxiliary film-forming substances can not constitute the film or the main body of the film, but have a great impact on the film-forming process (construction process), or play some auxiliary role in the performance of the film.
The auxiliary film forming materials include two main categories: solvent and auxiliary material.
(1) Solvents: Solvents are volatile liquids. The specific ability to dissolve film-forming substances can reduce the viscosity of the coating to meet the requirements of construction, but it affects the quality of film formation and the cost of the coating.
(2) Auxiliary materials: With film-forming substances, pigments and solvents form coatings, but generally in order to improve performance, some auxiliary materials are often used. There are many auxiliary materials in coatings, each has its own advantages, but the dosage is very small, usually several to a few thousandths or less. Although the dosage is small, the effect is remarkable. According to the function of auxiliary materials, it can be divided into drier, plasticizer, wetting agent, ultraviolet absorber, etc. At present, the amount of plasticizer used is more.
