Problems solved by technology

The color is mainly white, and there are also black, red, yellow, blue, etc. At present, the elasticity of colored resin microspheres is not high, the recovery, softness and toughness are poor, and the particle size is difficult to be consistent, resulting in the abrasion resistance of the coating surface. Injury is not good

Embodiment 1

[0009] Suede paint, according to the mass ratio: 25 parts of fluff powder, 30 parts of acrylic resin, 40 parts of cellulose acetate butyl solution, 2 parts of castor oil, 2 parts of dioctyl phthalate, 3 parts of defoamer, 3 parts of anti-settling agent, 8 parts of diluent, 6 parts of diphenylguanidine curing agent, 20 parts of sodium hydroxymethyl cellulose. The preparation method is as follows: first mix the fluff powder with resin and solvent, soak for 24 hours, disperse on a 3000rpm disperser, and then add the remaining components into the reaction kettle for mixing reaction. The coated suede paint was wiped 200 times by pressure-sensitive adhesive, and the gloss retention rate reached 77%. It was placed in an environment with a humidity of 80% for 15 days, and no obvious mildew was found.

Abstract

The invention relates to a suede-like coating which is prepared from the following raw materials in parts by mass: 25 parts of polymeric microsphere powder, 30 parts of acrylic resin, 40 parts of a cellulose acetate-butyrate solution, 2 parts of castor oil, 2 parts of dioctyl phthalate, 3 parts of a defoamer, 3 parts of an anti-settling agent, 8 parts of a diluent, 6 parts of a diphenyl guanidine curing agent and 20 parts of carboxymethyl cellulose sodium. Compared with the prior art, the suede-like coating has the characteristics that the process formula of the suede-like coating is obtained by exploration and the scratch resistance of the suede-like coating is better than that of the existing marketed product and the suede-like coating has a certain anti-mould property.

Description

technical field [0001] The invention belongs to the technical field of textile coatings, in particular to a suede coating. Background technique [0002] The suede coating is mainly composed of colored resin microspheres (or colored polymer microspheres, commonly known as fluff powder), base resin, solvents and additives. Its coloring is different from general paints in that it is colored with true spherical colored resin microspheres, while general paints are colored with inorganic or organic pigments. the [0003] The resin microspheres used in suede coatings are hollow, and the coloring pigments are encapsulated in the balls, so they are also called encapsulated pigments. The particle size of colored resin microspheres is generally 10~90um, preferably 10~30um. The color is mainly white, and there are also black, red, yellow, blue, etc. At present, the elasticity of colored resin microspheres is not high, the recovery, softness and toughness are poor, and the particle si...
