Problems solved by technology

[0003] In order to further improve the wear resistance and compressive strength of epoxy floor paint, people often choose to add some fillers (such as mica powder, glass powder, etc.) to epoxy floor paint to reinforce epoxy floor paint. , but these fillers themselves have a certain degree of inertness, and their compatibility with epoxy floor paint systems is poor. Too much filler content will affect the overall performance of epoxy floors, and too little addition will not achieve the desired effect. good reinforcing effect
At the same time, due to the long-term use of epoxy floor paint, chemical bonds will break due to factors such as friction, light, heat, and oxygen, resulting in aging and yellowing of the epoxy floor, which will affect the appearance and use experience of the epoxy floor. , the fillers in the epoxy floor will also gradually detach with the aging of the epoxy floor paint, which will affect the comfort of use

Abstract

The invention discloses wear-resistant impact-resistant waterborne epoxy floor paint and a preparation method thereof. The preparation method comprises the following steps: S1, preparing an allyltriphenylphosphonium bromide / graphene oxide compound; s2, preparing a quaternary ammonium salt polymer intermediate; and S3, preparing the wear-resistant impact-resistant waterborne epoxy floor paint. According to the invention, allyltriphenylphosphonium bromide is introduced into a graphene oxide sheet layer, and an allyltriphenylphosphonium bromide molecular chain can be utilized to expand the sheet layer structure of the graphene oxide, so that the interface bonding force between the allyltriphenylphosphonium bromide / graphene oxide compound and an epoxy floor paint system is increased; the wear resistance and the impact resistance of the epoxy floor are optimized; and the special phenylphosphine structure of the allyl triphenyl phosphonium bromide has high thermal stability, so that the weather resistance of the epoxy floor paint can be greatly improved, the aging of the epoxy floor paint is prevented, and the service life of the epoxy floor paint is greatly prolonged.
