Problems solved by technology

However, due to the high specific surface area of ​​graphene, there is van der Waals force between layers of graphene materials, so it is easy to agglomerate; in practical applications, graphene materials need to be dispersed in the medium, but graphene materials are hydrophobic and oleophobic, and easily Agglomeration, making it difficult to disperse in various media, greatly limiting its application

Abstract

The invention provides an epoxy floor coating, which comprises the following raw materials in parts by weight: 100 parts of a bisphenol A epoxy resin solution, 10-15 parts of a graphene microchip, 2-6parts of zinc powder, 0.5-1 part of polyamide wax slurry, 3-8 parts of n-butanol, 25-60 parts of xylene, 0.08-0.2 part of dibutyl phthalate and 0.1-0.2 part of polydimethylsiloxane. The graphene of the epoxy floor coating is uniformly dispersed and highly dispersed, so that the mechanical property of the graphene is brought into play, the impact resistance of the epoxy floor coating is effectively improved, the problem of electrical corrosion of the graphene is avoided, and the service life of the floor coating layer is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of epoxy coatings, and relates to a formula and a preparation method of epoxy floor coatings. Background technique [0002] Floor coatings are ground decoration materials that use epoxy resin raw materials as the main agent, adding pigments, solvents, and auxiliary curing agents. The research and production of epoxy oily floor paints all become floor coatings. Since the epoxy floor coating entered the Chinese market in the late 1980s, it has shown advantages that other types of coatings cannot achieve due to its excellent adhesion, mechanical strength and anti-corrosion performance, so it has won the welcome of the majority of users. with recognition. Epoxy floor coatings are one of the fastest growing areas of epoxy resin application technology in recent years. The modern industrial environment has various requirements for floor coatings (materials). For example, electronics, food, medicine and other industrial fie...
