Problems solved by technology

This will limit the application of epoxy floor coatings in factories with heating equipment, such as food factories with ovens, electronics factories that require heating and baking, etc. Some public entertainment places also require epoxy floor coatings to have a certain Excellent high temperature resistance and fire resistance performance, placing cigarette butts and other fire sources will burn the ground, causing the ground to appear brown and discolored
[0004] In order to prepare high-performance epoxy floor coatings, people often choose to add fillers such as glass fiber and mica powder to epoxy floor coatings to fill epoxy floor coatings. Although these materials have strong mechanical properties And better thermal insulation effect, can improve the wear resistance, compressive strength and high temperature resistance of epoxy floor coating to a certain extent, but the surface of these fillers is inert. It is prone to problems such as uneven dispersion and insufficient interfacial bonding with epoxy floor coatings, which has certain limitations on the improvement of the mechanical properties of epoxy floor coatings. At the same time, in the long-term use process, the filler also There will be peeling off, which will increase the difficulty of cleaning epoxy floor coatings
[0005] In order to further improve the fire resistance of epoxy floor coatings, people often choose to add some flame retardants to epoxy floor coatings. There will also be the problem of weak interfacial bonding between them, and the dispersion effect of the flame retardant is also difficult to be guaranteed. In the long-term frictional use process, there will inevitably be the problem of loss of flame retardant molecules, which reduces the durability of epoxy floor coatings. Flame retardant effect and long-term performance
