Problems solved by technology

The floor paint with a large amount of conductive mica powder as the conductive medium has a high cost and is difficult to promote on a large scale; the floor paint with conductive zinc oxide, carbon black, etc. as the conductive medium has a darker color, which affects the aesthetics of the floor paint. In addition, the processing is difficult; the floor paint products with conductive fibers as the conductive medium have poor dispersion, difficult to control the resistance value, and poor practicability

Abstract

The invention provides a coating of a water-based floor paint. In the paint film, graphene materials are flatly and uniformly distributed in the coating structure to form a graphene layer; and the graphene layer is positioned in the coating structure. E51 resin is adopted; several special auxiliary agents are used; particularly, rheology modified wax emulsion is adopted; graphene can be more orderly arranged during film formation of the paint by properly adjusting the use ratio, so that graphene can be more orderly arranged in the coating under the condition of less use amount, the formation of a continuous conductive net is facilitated, the conductivity is very good, and the anti-static capability of the paint is enhanced. The provided graphene static-conducting floor paint is an environment-friendly water-based paint, has extremely low VOC, also has the advantages of good adhesion, good corrosion resistance, good water resistance, good chemical resistance and the like, is simple in preparation process and strong in controllability, and is suitable for industrial mass production, popularization and application.

Description

technical field [0001] The invention belongs to the technical field of water-based floor paint, and relates to a paint film of a water-based floor paint, a water-based floor paint and a preparation method thereof, in particular to a paint film of a water-based graphene conductive static floor paint, a water-based graphene conductive Electrostatic floor paint and preparation method thereof. Background technique [0002] Graphene is a single layer of carbon atoms tightly packed into a two-dimensional hexagonal honeycomb lattice structure, and each carbon atom is connected by sp2 hybridization. Microscopically, the single-layer graphene film is not a two-dimensional flat structure, but has a "nanoscale" stable microwave-like single-layer structure, which is the only two-dimensional free-state atomic crystal found so far; macroscopically, graphite Alkenes can be warped into zero-dimensional fullerenes, rolled into one-dimensional carbon nanotubes or stacked into three-dimension...
