Embodiment 1

[0016] Put the lithopone into a grinder and grind until the particle size is less than 50 microns, transfer 2.5 kg of water, 0.2 kg of paraffin, 0.15 kg of glycerol and 0.4 kg of ground lithopone into a high-speed disperser, and grind at 1800 rpm Disperse for 50 minutes under the speed of rotation; transfer the obtained material to the mixer, add 0.5 kg of nano silicon dioxide, 0.7 kg of silicon acrylic emulsion and 4 kg of film-forming material in turn while stirring, control the stirring speed to 550 rpm, and mix well Detect the viscosity of the solution, when the viscosity of the mixed solution is 96KU, filter to obtain the scrub-resistant wall paint.

Embodiment 2

[0018] Put the lithopone into a grinder and grind until the particle size is less than 50 microns, transfer 30 kg of water, 2.5 kg of paraffin, 2 kg of glycerin and 3 kg of ground lithopone into a high-speed disperser, at 1500 rpm Disperse for 45 minutes under the speed of rotation; transfer the resulting material to the mixer, add 4 kg of nano-silica, 5 kg of silicon-acrylic emulsion and 30 kg of film-forming material successively while stirring, control the stirring speed to 600 rpm, and mix evenly Detect the viscosity of the solution, when the viscosity of the mixed solution is 93KU, filter to obtain the scrub-resistant wall paint.

Embodiment 3

[0020] Put the lithopone into a grinding machine and grind until the particle size is less than 50 microns, transfer 200 kg of water, 22.5 kg of paraffin, 10 kg of glycerol and 50 kg of ground lithopone into a high-speed disperser, at 1500 rpm Disperse for 60 minutes under the speed of rotation; transfer the obtained material to the mixer, add 30 kg of nano silicon dioxide, 60 kg of silicon acrylic emulsion and 350 kg of film-forming material in turn while stirring, control the stirring speed to 500 rpm, and mix well Detect the viscosity of the solution, when the viscosity of the mixed solution is 100KU, filter to obtain the scrub-resistant wall paint.

Abstract

The invention discloses a wipe-wash-resisting wall paint, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of water, 2 to 2.5 parts of paraffin wax, 1 to 2 parts of glycerine, 3 to 5 parts of nano silicon dioxide, 5 to 7 parts of silicone-acrylic emulsion, 3 to 5 parts of lithopone and 30 to 40 parts of film forming matter, wherein the film forming matter is composed of 35% of maleic anhydride modified rosin glyceride and 65% of rosin modified alkyd resin. The preparation method comprises the following steps: adding water, paraffin wax, glycerine and grinded lithopone into a high-speed dispersion machine to be dispersed uniformly; adding nano silicon dioxide, silicone-acrylic emulsion and the film forming matter in a mixture to be mixed uniformly; filtering the mixture when the viscosity is measured 93 KU to 100 KU to obtain the wipe-wash-resisting wall paint. The wipe-wash-resisting wall paint is excellent in wipe-wash-resisting performance, low in cost, and high in price performance ratio.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a scrub-resistant wall paint and a preparation method thereof. Background technique [0002] At present, commercially available wall paint usually uses polyvinyl acetate as a film-forming substance. In order to improve the performance of the product, more pigments and ultra-fine and relatively large fillers are added. These fillers have large oil absorption and specific surface area. Makes the paint film of the product bright and feels good. However, due to the excessive addition of pigments and fillers, the particle size of polyvinyl acetate is large, which is not conducive to film formation, resulting in dense paint film, poor weather resistance, and poor scrub resistance. Contents of the invention [0003] The object of the present invention is to provide a scrub-resistant wall paint and a preparation method thereof, which can solve the problem of poor scrub-...
