preparation example Construction

[0041] The preparation method of children's paint provided by the invention comprises the following steps:

[0042] Pre-mixing: Add dispersant, wetting agent, 0.1-0.2 parts by weight of defoamer and cellulose thickener to 17-20 parts by weight of water, and mix thoroughly to form a gel-like substance to facilitate the dispersion of pigments and fillers. The stirring speed can be controlled at 300-500RPM;

[0043]Grinding and dispersing: Add titanium dioxide, diatomaceous earth, and heavy calcium powder to the mixture, and control the speed at 2000-3000RPM for beating and grinding for 20-25 minutes. Check the beating and grinding until the fineness is ≤60um. Under the high shear rate of high-speed stirring, it is dispersed into primary particles, and a stable state of dispersion is obtained under the action of the dispersion aid system;

[0044] Add emulsion: After high-speed grinding and dispersing, add 3-5 parts by weight of water, preservatives, and anti-fungal agents to th...

Abstract

The invention provides a coating for children, which comprises the following components in parts by weight: 30-40 parts of volatile organic compounds (VOC)-free odorless emulsion, 6-10 parts of kieselguhr, 0.4-0.6 part of negative ion additive, 20-23 parts of titanium dioxide, 6-14 parts of heavy calcium powder, 0.4-0.7 part of dispersing agent, 0.1-0.3 part of wetting agent, 0.3-0.6 part of defoaming agent, 0.1-0.3 part of anti-freezing agent, 0.4-0.9 part of thickening agent, 0.1-0.2 part of preservative, 0.1-0.2 part of mildew preventive and 20-30 parts of tap water, wherein the thickening agent comprises 0.2-0.4 part of cellulose thickening agent and 0.2-0.5 part of acrylic acid thickening agent. The VOC content in the coating tends to zero. The coating is capable of adsorbing and removing harmful gases released from furniture and finishing materials and various indoor foreign odors, is capable of purifying indoor air and inhibiting bacterium and mould propagate, and has the effects of thermal insulation and noise reduction.

Description

technical field [0001] The invention relates to the field of coatings for interior wall protection and decoration, in particular to a children's coating and a preparation method thereof. Background technique [0002] At present, in view of the immature skin of newborns or children under 10 years old and the high requirements for the growth environment, young parents pay more and more attention to the environmental protection of home decoration materials. [0003] According to statistics from relevant departments, at present, about 800,000 children die each year in my country from upper respiratory tract infections caused by decoration pollution, of which more than 300,000 children under the age of 5 die because of indoor air pollution, especially in some newly built and newly renovated buildings. The indoor environmental pollution of kindergartens and families is very serious. Among the decoration and decoration materials for children's rooms, paints and paints have the grea...
