Abstract

The invention belongs to the technical field of paints, and particularly relates to a granite-like paint which is prepared by the following steps: adding 15 parts by weight of ethylene glycol, 2-4 parts by weight of dispersing agent, 40-50 parts by weight of 3% hydroxyethyl cellulose solution, 30-40 parts by weight of 10% inorganic gel, 1-2 parts by weight of wetting agent and 100-160 parts by weight of water into a dispersion kettle, dispersing uniformly, adjusting the rotation speed to 600 r / min, adding 500-550 parts by weight of granite powder, dispersing for 3-5 minutes, sequentially adding 3-4 parts by weight of defoaming agent, 50-70 parts by weight of rigid polymer emulsion, 50-60 parts by weight of elastic polymer emulsion and 5-6 parts by weight of film-forming assistant, stirring for 5 minutes, adding 10-15 parts by weight of thickener and 20 parts by weight of water, and dispersing for 30 minutes to obtain the granite-like paint. The granite-like paint has the stone sensation of the traditional natural stone paint. The coated film has comparable textures with the external wall ceramic tile, and has high simulation effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a granite imitation coating. Background technique [0002] As an important decorative material for building exterior walls, ceramic tiles have the characteristics of good durability, strong stain resistance and elegant appearance, but due to their excessive weight, it is difficult to firmly bond them to buildings, and they are often injured due to falling off. People (objects), and the bearing capacity of the surface of the external thermal insulation system is limited, which will cause unnecessary losses and dangers due to easy peeling off. [0003] At present, the mainstream method of replacing ceramic tiles is to achieve by spraying real stone paint. The realization method is to use granite stone powder and organic polymer emulsion to compound, and spray it on the wall through a pressure spray gun. However, due to the need for relatively large air pressure during spraying, t...
