Special paint for internal walls and preparation method thereof

Abstract

The invention discloses a special paint for internal walls, which is composed of the following components in parts by weight: 200-300 parts of water, 1-3 parts of alkaloid, 1-3 parts of wetting agent, 2-5 parts of dispersant, 2-4 parts of defoaming agent, 150-250 parts of titanium white, 50-100 parts of calcium carbonate powder, 50-100 parts of cattle bone meal, 150-250 parts of acrylic acid emulsion, 20-50 parts of vegetable jelly composition, 2-4 parts of ethanol and 3-5 parts of plant extract. The paint has the advantages of simple preparation technique and low cost, has favorable moldproof, insect expelling and sterilization effects by the combination of the cattle bone meal, plant extract and vegetable jelly, and smells fresh. The paint is free of formaldehyde, benzene, ammonia and other toxic substances, can achieve zero emission of volatile toxic substances, and can absorb formaldehyde and other harmful substances emitted by indoor floor, furniture and the like. The paint has favorable air permeability, enables the wall surface to have the function of ventilation, and automatically regulates the indoor air humidity.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a special coating for interior walls and a preparation method. Background technique

[0002] With the rapid development of the paint industry, various special paints for interior walls emerge in endlessly. Manufacturers attract the attention of consumers in terms of color, material and safety. , usually prone to the following problems: the wall is prone to mildew or oxidation, causing the paint to fall off, especially during the rainy season in the south, when the air is humid, it is more likely to have mildew on the interior wall, and the water resistance is poor. Bring a lot of inconvenience; Most of the existing paint products contain certain harmful substances such as formaldehyde and volatile organic compounds, which usually emit an unpleasant smell for a long time, and the environmental protection performance is poor, which brings lasting damage to people's bod...
