Weathering-resistant natural composite material and preparation method thereof

Abstract

The invention relates to a weathering-resistant natural composite material and a preparation method thereof. The composite material consists of the following components in parts by weight: 50-75 partsof natural stone powder, 5-8 parts of styrene-acrylic emulsion, 3-6 parts of a propylene glycol auxiliary agent, 3-6 parts of an AMP-95 multifunctional auxiliary agent, 5-8 parts of an HT-608 thick slurry defoaming agent, 0.5-1 part of nickel sulfate hexahydrate, 3-6 parts of a 2-3% sodium hydroxide solution, 6-8 parts of polyoxyethylene ether lauryl sulfate sodium, 5-8 parts of cross-linked polyvinylpyrrolidone, 3-6 parts of tridefluxintriethoxysilane, 3-5 parts of bleaching powder, 0.2-0.6 part of sodium thiosulfate, 3-8 parts of a PP toughener, and a proper amount of pigment. The weathering-resistant natural composite material provided by the invention is not only mildew-proof and waterproof but also increases the elasticity and plasticity of a wall surface, and the effect after construction is uniform and beautiful, and the brightness is obviously improved. The raw materials are mostly wastes, the price is low, the secondary utilization of the wastes is achieved, the environment is protected, and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to a weather-resistant natural composite material and a preparation method thereof. Background technique [0002] At present, expensive organic coating materials such as polyvinyl alcohol, titanium dioxide, and lithopone are commonly used in interior wall coatings for general buildings in China, which are easy to fall off, are not washable and moisture-proof, and are likely to cause secondary pollution. In addition, the mortar of lime powder and lime paste has low viscosity, low hardness and wall crack resistance, high cement consumption, and poor moisture-proof and air-permeable properties. Ceramic tiles are widely favored by developers and owners for their solemn texture, durable quality and diverse colors. However, the disadvantages of this material are also obvious: one is expensive, the other is complicated construction, the third is difficult to combine with thermal insulation materials, the fourth is low safety factor, and...
