Abstract

The invention discloses a preparation process of a low-cost environment-friendly inner wall coating, which comprises three steps: preparation of straw powder, preparation of mixtures and preparation of the coating. The preparation process is simple, the preparation condition scope is wider, and the operation is easy. As adopted raw material has a wide source, the cost is low, and particularly a large proportion of reproducible straw powder is used, the cost of the coating can be greatly reduced, and the coating is environment friendly.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a preparation process of a low-cost environment-friendly interior wall paint. Background technique [0002] There are two main types of architectural coatings currently produced in my country: one is synthetic resin latex, including ethylene-propylene latex paint, styrene-acrylic latex paint, vinyl chloride-vinylidene chloride latex paint, polyvinyl acetate latex paint, epoxy-acrylic latex paint The second is inorganic polymers, mainly including various inorganic architectural coatings formulated on the basis of silicate and silica sol. [0003] With the application of interior decoration materials more and more widely, human beings are beginning to enter the third generation of pollution period marked by indoor pollution. It is internationally recognized that indoor pollution is the most harmful place to public health. The characteristics of indoor air pollution are...
