在地面涂料的选择上人们注重功能性强的地面施工材料，除此之外在安全性和环保性上也是非常重要的一项。特别是在一些绿色企业和家庭施工中尤为突出。因此，这类的客户比较在意环氧地坪漆的成分是否含有毒性？是否安全，是否环保？这里就来给大家介绍一下环氧地坪漆材料的组成成分。

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.

环氧地坪漆由多种不同物质经混合，溶解，分散等生产工艺而组成。按环氧地坪漆各组分的作用不同，一般可分主要膜物质，次要成膜物质和辅助成膜物质。

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.

我国环氧环氧地坪漆的主要基料以合成树脂为主：

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）环氧树脂：环氧树脂用于地坪涂料时，常采用低分子量的聚酰胺树脂固化，目前环氧树脂在地坪上用无缝地面涂布材料，水乳型外墙涂料的主要基料。

(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.

次要成膜物质：

Secondary film-forming material:

次要成膜物质也是构成涂膜的重要组成部分，但它不能离开主要成膜物质单独成涂膜。这种成分就是涂料中使用的颜料。在涂料中加入颜料，不仅能使涂膜性能得到改进，并且使涂料品种有所增多。

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.

辅助成膜物质：

Auxiliary film forming material:

辅助成膜物质不能构成涂膜或不是构成涂膜的主体，但对涂料的成膜过程（施工过程）有很大的影响，或对涂膜的性能起一些辅助作用。

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.

辅助成膜物质主要包括溶剂和辅助材料两大类 ：

The auxiliary film forming materials include two main categories: solvent and auxiliary material.

（1）溶剂：溶剂是能挥发的液体，具体溶解成膜物质的能力，可降低涂的粘度达到施工的要求，但它影响涂膜的形成质量和涂膜的成本。

(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）辅助材料：有了成膜物质，颜料和溶剂就构成了涂料，但一般为了改善性能，常使用一些辅助材料，涂料中所使的辅助材料很多，各具特长，但用量很少，一般是百分之几到千分之几或更少。用量虽少，但作用显著。根据辅助材料的功能可分为催干剂，增塑剂，润湿剂，紫外线吸收剂等。目前以催干剂，增塑剂使用数量较多。

(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.
