Problems solved by technology

[0003] The present invention aims at the existing problems: the natural stone powder added in the real stone paint is mainly composed of calcium carbonate, which is directly used without processing, and the natural stone powder has a high shrinkage rate, which will cause the appearance of the real stone paint Bubbling, dry cracking and other phenomena lead to quality decline; and natural stone powder is used as the main raw material, which has strong alkali resistance, but its calcium component is decomposed by acid, and the acid resistance is relatively poor, and the surface is prone to pits and discoloration. , affect the practical aesthetics of real stone paint

Abstract

The invention discloses low-shrinkage-rate real stone paint. The low-shrinkage-rate real stone paint is characterized in that the real stone paint is prepared from the following main preparation components: pure acrylic emulsion, castor oil emulsion, silicone acrylic resin emulsion, modified real stone powder, modified bamboo fiber powder, a film-forming agent, butyl acetate, a dispersant, a stabilizer and titanium white; a processing method of the modified real stone powder comprises the steps of crushing and filtering, heating and cracking, carrying out degradation and carrying out siliconization treatment; a processing method of the modified bamboo fiber powder comprises the steps of carrying out acidizing treatment, steaming and carrying out ammonization reaction.

Description

technical field [0001] The invention belongs to the technical field of real stone paint processing, and in particular relates to a low shrinkage real stone paint product. Background technique [0002] Real stone lacquer is a kind of paint with decorative effect similar to marble and granite texture. It is mainly made of various natural stone powder and paint ingredients; it has natural and real natural color, giving people a sense of elegance, harmony and solemnity. Suitable for indoor and outdoor decoration of various buildings; real stone paint has the characteristics of fire prevention, waterproof, non-toxic, tasteless, strong adhesion, and never fades. It has excellent cold resistance and is often used in cold regions. However, the natural stone powder added to the real stone paint is mainly composed of calcium carbonate, which is used directly without processing. The natural stone powder has a high shrinkage rate, which will cause blistering and dry cracking on the sur...
