Embodiment 1

[0022] The present invention proposes a kind of preparation method of green environmental protection inner wall latex, comprises the following steps:

[0023] S1. Weigh water, dispersant, surfactant, film-forming aid, defoamer, thickener, and fungicide into the batching tank according to the proportion, and stir at a low speed for 5-10 minutes;

[0024] S2, then add fillers and pigments, disperse at high speed for about 30 minutes, and enter the sand mill (or other grinding equipment) to grind to a fineness below 50 μm;

[0025] S3, add the solution obtained in S2 into the paint tank, then add the emulsion, and start stirring at a low speed for 10-13 minutes;

[0026] S4, adding defoamer and preservative, here the defoamer adopts SPA-102 compound defoamer composed of ether ester compound and organic phosphate; preservatives are sodium pentachlorophenate, phenylmercury acetate and tributyltin, etc. , the efficiency of phenolic compounds is low, the dosage is generally 0.2%, th...

Abstract

The invention discloses a raw material composition of green and environment-friendly interior wall latex. The raw material composition is prepared from the following raw materials in parts by weight:20 to 40 parts of water, 0.05 to 0.07 part of a microorganism killing agent, 0.02 to 0.04 part of a film-forming auxiliary agent, 0.03 to 0.05 part of a thickening agent, 0.004 to 0.006 part of a pigment dispersant, 0.04 to 0.06 part of a de-foaming agent, 0.008 to 0.01 part of a wetting agent, 35 to 55 parts of emulsion, 0.06 to 0.08 part of a neutralizing agent and 0.002 to 0.04 part of a preservative. According to the raw material composition, the water, the microorganism killing agent, the film-forming auxiliary agent, the thickening agent, the pigment dispersant, the de-foaming agent, thewetting agent, the emulsion, the neutralizing agent and the preservative and the like are added, and the raw material composition does not contain any substance, so that body health of a user is protected; meanwhile, the raw material composition has relatively good film forming performance, water resistance and pollution resistance.

Description

technical field [0001] The invention relates to the technical field of decoration, in particular to a preparation method of green and environment-friendly interior wall latex. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to their own health. In recent years, reports on the relationship between newly renovated indoor air pollution and the incidence of leukemia have also been seen in the media. Therefore, people pay more and more attention to the environmental protection of decoration materials when decorating. In the interior decoration process, the materials contain more or less harmful substances such as formaldehyde and benzene series, which will gradually emit in the years or even decades after the decoration, thus affecting the health of the human body. The materials used in the current interior wall latex are not Environmental protection, easy to cause damage to the human body. [0003] For this r...
