Problems solved by technology

All kinds of environmental protection paints, healthy paints, and odor-cleaning paints on the market are almost difficult to achieve zero pollution. They often cover up the defects of the paint itself that may volatilize harmful substances under the guise of purifying the air, releasing negative ions, and decomposing formaldehyde.

Embodiment 1

[0020] Add 0.75 parts of wetting and dispersing agent, 0.2 parts of defoamer, and 1.5 parts of propylene glycol into 15 parts of deionized water, mix well to form a premix; add 5 parts of titanium dioxide, 6.5 parts of kaolin, light carbonic acid 12.5 parts of calcium, 8 parts of talcum powder, 20 parts of heavy calcium carbonate, dispersed and ground into pigment slurry;

[0021] Mix 0.3 parts of bactericide, 0.7 parts of film-forming aids, 0.15 parts of pH regulator, and 0.4 parts of cellulose with the remaining 15 parts of deionized water, and then add them to 10 parts of modified acrylic emulsion together with the pigment slurry;

[0022] Finally, add 0.4 part of thickener to adjust the viscosity to 100KU to obtain the finished paint.

Embodiment 2

[0024] Add 1 part of wetting and dispersing agent, 0.1 part of defoamer, and 1 part of propylene glycol to 10 parts of deionized water, and mix well to form a premix; add 2 parts of titanium dioxide, 5 parts of kaolin, and light carbonate to the premix. 15 parts of calcium, 5 parts of talcum powder, and 15 parts of heavy calcium carbonate are dispersed and ground into a pigment slurry until the particle size is 1000-1250 mesh;

[0025] Mix 0.1 part of bactericide, 0.5 part of film-forming aid, 0.5 part of pH regulator, and 0.3 part of cellulose with the remaining 10 parts of deionized water, and then add them to 8 parts of modified acrylic emulsion together with the pigment slurry;

[0026] Finally, add 0.3 parts of thickener to adjust the viscosity to 105KU to obtain the finished paint.

Embodiment 3

[0028] Add 0.5 parts of wetting and dispersing agent, 0.3 parts of defoamer, and 2 parts of propylene glycol into 20 parts of deionized water, and mix well to form a premix; add 8 parts of titanium dioxide, 8 parts of kaolin, and light carbonic acid to the premix. 10 parts of calcium, 10 parts of talcum powder, and 25 parts of heavy calcium carbonate are dispersed and ground into a pigment slurry until the particle size is 1000-1250 mesh;

[0029] Mix 0.5 parts of bactericide, 1 part of film-forming aid, 0.1 part of pH regulator, and 0.5 part of cellulose with the remaining 20 parts of deionized water, and then add them to 12 parts of modified acrylic emulsion together with pigment paste;

[0030] Finally, add 0.5 part of thickener to adjust the viscosity to 95KU to obtain the finished paint.

Abstract

The invention discloses an environmental-friendly waterborne coating for building inner wall decoration. The environmental-friendly waterborne coating is prepared from the raw materials in parts by weight: 20-40 parts of deionized water, 0.3-0.5 part of cellulose, 0.5-1.0 part of a wetting dispersant, 0.1-0.3 part of a defoamer, 0.1-0.2 part of a pH regulator, 2-8 parts of titanium dioxide, 5-8 parts of kaolin, 10-15 parts of light calcium carbonate, 5-10 parts of talc, 15-25 parts of heavy calcium carbonate, 8-12 parts of acrylic emulsion, 0.1-0.5 part of a fungicide, 1-2 parts of propanediol, 0.5-1.0 part of a film-forming additive and 0.3-0.5 part of a thickener. The environmental-friendly waterborne coating has the characteristics of good coating effect, low harmful matter content, soft smell, low production cost, good stability and long service life.

Description

[0001] technical field [0002] The invention belongs to the field of building materials and relates to a water-based paint, in particular to an environment-friendly water-based paint for interior wall decoration of buildings and a preparation process thereof. Background technique [0003] About 70% to 90% of people's life is spent indoors. If there are too many harmful substances in the room, it may cause various diseases of the human body. A large number of facts have proved that many diseases of people, such as dizziness, Fatigue, lung disease, diarrhea, allergies, air-conditioning disease, obesity, etc., are all related to living conditions. More serious ones such as leukemia, cancer, neonatal deformities, and mental decline in children are also directly related to excessive harmful gases and substances in the residence. All kinds of environmental protection paint, healthy paint, and odor-cleaning paint on the market are almost difficult to achieve zero pollution. They ...
