Sand wall-shaped texture paint and preparation method thereof

Abstract

The invention discloses sand wall-shaped texture paint and a preparation method thereof. The method includes preparation of pigment and filler dispersing paste and preparation of paint. According to a preparation formula of the pigment and filler dispersing paste, the pigment and filler dispersing paste includes 0.8% of hydroxyethyl cellulose, 40% of deionized water, 5% of ethylene glycol, 1.5% of alcohol ester, 0.3% of defoaming agent, 0.3% of wetting agent, 0.6% of dispersing agent, 20% of titanium dioxide, 18% of iron oxide red, 20.8% of talcum powder, 21.6% of calcium carbonate and 58.4% of river sand; after the pigment and filler dispersing paste is prepared, other ingredients are added to prepare the paint, wherein the ingredients include 65-75% of pigment and filler dispersing paste, 20-30% of emulsion, 0.5% of leveling agent, 0.3% of defoaming agent, 1-10% of alcohol ester and 0-1% of thickening agent. With the low-cost river sand easy to take being the main filler, the sand wall-shaped external wall brick-imitating paint is prepared; the preparation method is simple in technology, and the paint is healthy, environmentally friendly, excellent in performance, free of bulging, cracking, peeling or other problems, and good in stability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sand wall texture coating and a preparation method thereof. Background technique [0002] Exterior wall decoration is an important part of modern building design and construction, and modern building exterior wall decoration is developing towards the direction of ecological environmental protection and energy saving. Building exterior wall decoration materials mainly include the following types: ceramic tiles, stone materials, curtain walls, panels and exterior wall coatings. The production of ceramic face bricks needs to consume land resources, high-temperature roasting consumes a lot of energy, the process is complicated, and the cost is relatively high; stones such as granite and marble have rich textures, but they are heavy and easy to peel off; glass curtain walls are light in weight and beautiful, but there are light pollution, Easy to stain, poor self-cleanin...
