Epoxy resin has a certain degree of thermoplasticity, which needs to react with curing agent or fatty acid to form a network structure of macromolecules, from its thermoplasticity to thermosetting, thus showing a variety of excellent properties. Among them, epoxy resin floor paint has many properties, and each has its own characteristics. Nowadays, epoxy floor paint has been widely used in cement or terrazzo floor of electrical appliances, food, medicine, clothing, stationery, printing and dyeing, hardware and plastic factories. It can also be used in schools, libraries, indoor parking lots, etc. Let's learn about the composition and advantages of epoxy floor paint.
Two. Epoxy resin floor paint raw material composition and Description:
1. epoxy resin and curing agent: after reaction, non-toxic, in line with FDA non-toxic requirements. FDA is the United States Food and drug administration.
2. Solvent: In the process of construction and film drying, solvent volatilization is harmful to the environment and human body, should try to choose the solvent with little harm to human body and strengthen ventilation to reduce the concentration. After drying the coating, the solvent volatilization will not damage the environment and human body.
3. auxiliaries: the amount of auxiliaries in the coating is very small, and has little effect on the toxicity of the coating.
Three. Main components and instructions for epoxy floor paint.
1. Epoxy resin sealing primer: The cured substance after the reaction of epoxy resin and curing agent is non-toxic, which meets the requirements of non-toxicity of FDA.
2. Epoxy medium-coated mortar: epoxy resin and curing agent and quartz sand and quartz powder composition, the cured product after reaction is non-toxic, in line with the non-toxic requirements of FDA;
3. quartz powder and quartz sand: the product after crushing and screening for natural minerals is non-toxic.
Four. The advantages of epoxy floor paint are:
1. Excellent adhesion: Epoxy floor coating has many hydroxyl and ether bonds, so it can be adsorbed with the substrate material. And the volume shrinkage of epoxy resin curing is low, so the film has excellent adhesion to metal, ceramics, glass, concrete, wood and other polar substrates.
2. Epoxy resin floor has a certain wetting force on the wet surface. Especially when polyamide resin is used as curing agent, it can be made into underwater coating, which can expel water from the surface of the object and be used for rush repair of underwater structures and anti-corrosion construction of underwater structures.
3. Epoxy floor itself is not high in molecule, can be used with a variety of curing agents to produce solvent-free, high solid powder coatings and water-based coatings, in line with environmental requirements, and can obtain thick film coating.
4. Epoxy resin floor contains epoxy group and hydroxyl group. It can be combined with polyamine, polyamide resin, phenolic resin, amino resin, polyisocyanate and so on to make a variety of coatings. It can be dried at room temperature and baked at high temperature to meet different construction requirements.
