Problems solved by technology

Batch-scratch type texture paint has high requirements for construction. It is required that the product should be smooth and smooth when scraping, and the knife should not be stuck. It is required to use textured sand particles that are as round as possible to facilitate construction. Shaped sand, the cost is too high, the energy consumption is too large, and the dust pollution is serious, which does not meet the requirements of energy conservation and environmental protection
In the production of paint or ink, in order to grind the pigments and fillers to the required particle size, a horizontal sand mill is used for grinding. The sand abrasive in the inner cavity of the horizontal sand mill is generally small glass beads or zirconia beads with high hardness. After a certain period of use, the wear will become smaller and the grinding efficiency will be reduced. It must be replaced. The replaced beads are mostly discarded because they are useless.

Abstract

The present invention relates to a scratch-type sand wall texture coating material and a preparation method thereof, wherein the raw materials comprise, by mass, 12.00-20.00% of a texture Lacquer emulsion, 2.00-4.00% of a pigment, 3.00-5.00% of a filler, 0.10-0.20% of a wetting agent, 0.20-0.40% of a dispersing agent, 0.02-0.05% of a PH value regulator, 0.10-0.30% of an anti-foaming agent, 0.10-0.20% of a preservative, 0.05-0.15% of hydroxyethyl cellulose, 0.2-0.5% of aqueous bentonite, 0.20-0.50% of a thickener, 0.60-1.00% of a film-forming aid, 0.30-0.60% of an anti-freezing agent, 0.00-35.00% of texture sand, 35.00-75.00% of fine beads, and 5.00-7.00% of water. According to the present invention, the scratchability of the existing scratch-type texture coating material is improved, the waste grinding medium glass beads and / or the zirconium oxide beads are re-utilized, and the scratchability is significantly improved; the waste glass beads or zirconium oxide fine beads are completely utilized so as to turn the waste into treasure; and the texture sand consumption is reduced, such that the energy source consumption and the dust pollution caused by the production of the texture sand are reduced.

Description

technical field [0001] The invention relates to the field of coatings, in particular to exterior wall coatings, in particular to a batch-scratch type sand wall texture coating and a preparation method thereof. Background technique [0002] In recent years, in the exterior wall decoration of our country, pattern texture paint decoration has gradually become the mainstream of building exterior wall decoration, accounting for more than 70% of exterior wall paint decoration. Textured coatings have a strong three-dimensional pattern and strong decorative properties. In addition, the thickness of the paint film is much larger than that of conventional flat-coated exterior wall products, and the anti-cracking effect is good. This is the reason why textured coatings are widely used in exterior wall decoration. Batch-scratch type texture paint has high requirements for construction. It is required that the product should be smooth and smooth when batch-scraping without stagnation of ...
