Problems solved by technology

However, the existing interior wall paint has a cold and stiff texture, lacks aesthetic feeling, and is not outstanding enough in function
In the low temperature season, the texture of the wall surface is cold, which makes people feel uncomfortable when touched, and the hand feel is not smooth enough; in the rainy season, due to the high ambient humidity, the wall paint film is prone to condensation, which cannot help adjust the indoor humidity
In addition, due to the dense internal structure of the existing wall paint film, the thermal conductivity is relatively large, and the speed of sound propagation in it is fast, so it cannot play the role of sound insulation and heat insulation.

Abstract

The invention discloses a soft hand feel coating which comprises expandable microsphere pulp, styrene-acrylate emulsion, dispersant, wetting agent, film-forming additive, anti-freezing agent, defoaming agent, thickener, anti-mildew agent, preservative, titanium dioxide, kaolin, triple(concentrated) superphosphate and water, wherein, the expandable microsphere pulp consists of 10%-15% of expandable microspheres and 85%-90% of water by weight percent. The process comprises the steps of pre-mixing, grinding, dispersing, adding the emulsion, adding the additives and adding the expandable microsphere pulp. The expandable microspheres added in the coating change the structure and the texture of the surface of a paint film and soften the touch; additionally, the expandable microspheres in the paint film improve the porosity of the paint film and reduce the spread-ability of heat and sound in the paint film, pores of the paint film can play the regulating role on water in the air, the water is absorbed when the humidity is high, and the water is released when the humidity is low.

Description

technical field [0001] The invention relates to the technical field of coatings for interior wall decoration and protection and their preparation, in particular to a soft hand-feeling coating with a smooth hand feel and texture like supple fabrics, capable of adjusting indoor humidity, sound insulation and heat insulation, and a preparation method thereof . Background technique [0002] In recent years, people's demand for interior wall coatings has become more and more personalized and functional. However, the existing interior wall coatings have a cold and stiff texture, lack aesthetic feeling, and are not prominent enough in functionality. In the low temperature season, the texture of the wall surface is cold, which makes people feel uncomfortable when touched, and the hand feel is not smooth enough; in the rainy season, due to the high ambient humidity, the wall paint film is prone to condensation, which cannot help adjust the indoor humidity . In addition, because th...
