Abstract

The invention provides graphene waterborne super-wear-resisting floor paint and a preparation method thereof. The floor paint is prepared from the following components in parts by weight: 60 to 75 parts of polyurethane resin, 8 to 11 parts of modified graphene, 7 to 11 parts of hydroxyethyl cellulose, 15 to 20 parts of dimethylaminoethyl acrylate, 5 to 9 parts of nano zinc oxide, 9 to 17 parts ofnano silicon dioxide, 15 to 26 parts of curing agent, 0.5 to 1.5 part of dispersant, 0.9 to 1.8 parts of flatting agent, 0.4 to 0.8 part of de-foaming agent, 3 to 5 parts of active diluting agent, 30to 60 parts of pigment and filler and 15 to 30 parts of water. According to the graphene waterborne super-wear-resisting floor paint provided by the invention, the wear-resisting performance and mechanical performance of a coating paint film are enhanced; a preparation technology is simple and a prepared product meets the environment-friendly requirements; the graphene waterborne super-wear-resisting floor paint is safe and environmentally friendly and has a wide applicable range.

Description

technical field [0001] The invention relates to the technical field of floor paint, in particular to a graphene water-based super wear-resistant floor paint and a preparation method thereof. Background technique [0002] Graphene is a single layer of carbon atoms tightly packed into a two-dimensional hexagonal honeycomb lattice structure, with sp 2 connected in a hybrid manner. 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-dimensional graphite. The existence of stable carbon six-membered rings in graphene's unique two-dimensional periodic honeycomb lattice structure endows it with excellent performance: the thickness of single-layer graphene is ...
