Epoxy floor is a kind of high-strength, abrasion-resistant and beautiful floor. It has the advantages of no joints, solid texture, good chemical resistance, anti-corrosion, waterproof, dustproof, convenient maintenance, and low maintenance costs. Epoxy floors were initially used for functional floors: such as anti-corrosion, wear resistance, and non-slip, developed to general industrial floors; in addition to functional requirements, they also have decorative effects. On the basis of the widespread application of industrial floors, with the continuous improvement of people's living standards, it has now been promoted and applied in home decoration. Epoxy flooring has become one of the fastest-growing industries in my country, attracting everyone's attention. It can realize factory production like cement products, and the prospect is even more impressive!

　　Commonly used curing agents and their effects on the performance of epoxy coatings. There are many types of curing agents for epoxy resins, reaching dozens of them. Commonly used are various amines (such as aliphatic amines and alicyclic amines) and resin curing agents. According to the curing agent curing mechanism of epoxy resin, it can be divided into three categories: curing agent which reacts with epoxy group of epoxy resin, curing agent which reacts with epoxy group and curing agent which reacts with hydroxyl group of epoxy resin. The last category is mainly some resins that can react with epoxy resins, such as phenolic resins containing methylol or alkoxy groups, melamine resins and polyisocyanates. Among the amine curing agents, alicyclic amines and their adducts have light color, good leveling, high gloss, no whitening, and no induction period, but their glass transition temperature is higher and their flexibility is poor. They are mainly used As the curing agent for solvent-free epoxy floors, it is necessary to add toughening agents such as polysulfide rubber, long-chain alkyl hydroglyceride, and elastic polyurethane at the same time. Fatty amine amino-terminated polyether has a fast curing speed, and the curing temperature is close to room temperature, which greatly improves the flexibility, toughness and chemical resistance of epoxy resin products. It is a new type of curing agent.
