Problems solved by technology

[0002] There are many types of interior wall paints on the market, most of which are composed of base materials, additives and fillers. The amount of fillers added is generally about one-third, because most of the interior wall paints on the market contain formaldehyde and benzene Exceeding the standard, it has a pungent smell that is poisonous and harmful to the human body, and it will greatly affect people's physical and mental health when painted on indoor walls, while imported paints are expensive and often have problems such as mildew, curling, and cracks, which affect people's normal use

Abstract

The invention discloses high calcium chemical paint, and belongs to a polymer compound category. The paint is suitable for interior decoration of homes and offices. The paint is characterized in thatthe paint consists of (wt%) 30-40 wt% of a base-material and an auxiliary agent and 60-70 wt% of a filling material, wherein the base-material consists of polyvinyl alcohol, a thickener solution (protective glue), an acrylic emulsion and water (substituting an organic solvent), the auxiliary agent consists of a fluorescent whitening agent and an antifoaming agent, and the filling material consistsof ultrafine ground calcium carbonate, and also can consist of ultrafine ground calcium carbonate and light calcium carbonate or ash calcium. The paint does not contain the organic solvent like formaldehyde and benzene; the adding amount of the cheap filling material accounts for 60-70% of the total amount of the paint; the paint is non-toxic and tasteless, has no radioactivity, good waterproofness and strong adhesion; and the paint is suitable for various walls, and has characteristics of non-cracking, non-peeling and non-moulding.

Description

technical field [0001] The invention relates to a coating, in particular to a high-calcium chemical coating, which belongs to the category of polymer compounds and is suitable for use in decoration of homes and offices. Background technique [0002] There are many types of interior wall paints on the market, most of which are composed of base materials, additives and fillers. The amount of fillers added is generally about one-third, because most of the interior wall paints on the market contain formaldehyde and benzene Exceeding the standard, it has a pungent smell that is poisonous and harmful to the human body. It will greatly affect people's physical and mental health when painted on indoor walls. However, imported paint is expensive and often has problems such as mold, curling, and cracks, which affect people's normal use. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provid...
