Graphene high-performance stone-like paint and preparation method thereof

Abstract

The invention discloses graphene high-performance stone-like paint and a preparation method thereof. The graphene high-performance stone-like paint comprises a component A and a component B, wherein the component A comprises the following raw materials according to a mass permillage: 70-130%o of deionized water, 1-3%o of a defoamer, 4-7%o of a dispersant, 0.1-1%o of graphene, 3-8%o of a thickener,110-180%o of water-based resin, 5-10%o of a coalescing agent, 550-750%o of natural color sand and 0-200%o of a rock sheet; and the component B comprises the following raw materials according to the mass permillage: 700-800%o of a curing agent and 200-300%o of the coalescing agent. The preparation method comprises the following steps: (1) adding the deionized water to a dispersion tank, successively adding the defoamer, the dispersant, the graphene, the water-based resin, the coalescing agent and the thickener, after uniformly stirring, adding the color sand and/or the rock sheet; and (2) adding the curing agent and the coalescing agent to the dispersion tank, uniformly stirring to obtain the graphene high-performance stone-like paint. The graphene high-performance stone-like paint has theadvantages of excellent stain resistance, adhesive force, cracking resistance, water resistance, alkali resistance and temperature variation resistance and the like.

Description

technical field [0001] The invention relates to a coating for exterior wall decoration, in particular to a graphene high-performance real stone paint and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of natural stone sand of various colors, which is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. The buildings decorated with real stone paint have natural and real natural color, which gives people a sense of elegance, harmony and solemnity. It is suitable for indoor and outdoor decoration of all kinds of buildings, especially on curved buildings. It is vivid and lifelike. A return to nature effect. Graphene is a two-dimensional material with a thickness of only one carbon atom. It has a special honeycomb lattice structure. It is also the material with the highest mechanical strength known to mankind....

AI Technical Summary

Problems solved by technology

This difference is in the one-component resin paint, the paint film is prone to many defects, such as the large porosity of the paint film, low hardness, easy to cause microbial growth, decreased anti-fouling, and water resistance, alkali resistance and aging resistance are not as good as double Component paint film

Therefore, based on the shortcomings of one-component resin paint, it has seriously affected the decorative effect and service life of real stone paint as exterior wall paint.
