Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the poor adhesion of the existing textured paint, cracking or peeling is easy to occur after use, causing rainwater to penetrate into the wall surface, corrode the wall surface, affect the appearance, and greatly reduce the decorative effect. First, distilled water, propyl trichlorosilane and other substances are stirred and mixed, then placed in a high-pressure reactor, and then butyl acrylate, methyl methacrylate and other substances are added for heating reaction. After natural cooling, hydroxymethyl Sodium cellulose and methyl salicylate continue to mix and react to obtain a high-adhesion texture paint base material, and finally mix it with quartz sand, propylene glycol butyl ether and other substances to obtain a high-adhesion texture paint

Abstract

The invention relates to a preparation method for a textured paint with high adhesion, which belongs to the technical field of preparation of textured paints. The preparation method comprises the following steps: mixing distilled water, propyltrichlorosilane and other substances under stirring and placing the obtained mixture in a high-pressure reaction vessel; then adding butyl acrylate, methyl methacrylate and other substances and carrying out a heating reaction; after natural cooling, adding sodium hydroxymethyl cellulose and methyl salicylate and continuing a mixing reaction so as to obtain a base material for the textured paint with high adhesion; and mixing the base material, quartz sand, propylene glycol butyl ether and other substances under stirring so as to obtain the textured paint with high adhesion. The textured paint prepared in the invention has high adhesion; after usage, the bonding strength of the textured paint reaches 1.3 MPa or above in a standard state; after soaking in water, the bonding strength of the textured paint reaches 0.9 MPa or above, and the phenomena of shedding and peeling hardly occur; and the textured paint has good pollution resistibility and stain resistance of grade 2 or above.

Description

technical field [0001] The invention relates to a method for preparing a high-adhesion texture paint, which belongs to the technical field of texture paint preparation. Background technique [0002] Texture paint is made of acrylic acid polymer, high-quality additives and natural sand. It is a thick-build paint for interior and exterior walls, with a variety of natural decorative effects; good flexibility, impact resistance, waterproof and breathable, stain resistance, etc.; simple construction , Through different construction methods, it can create a decorative effect with strong texture and different styles. The current texture paint is mainly composed of emulsion, additives, and natural sand. The emulsion is a polymer material with the characteristics of elasticity, water resistance, and weather resistance. The texture paint prepared by emulsion and natural sand material fully embodies the comprehensive advantages of mineral system paint and synthetic resin system paint:...
