Abstract

The invention relates to an antibacterial latex paint containing natural jade powder and a preparation method for the same. The antibacterial latex paint contains the following ingredients in parts by weight: 50-150 parts of natural jade powder, and 5-15 parts of nanometre inorganic anionic auxiliary, wherein the grain diameter of the natural jade powder is 3000-6000 meshes. The latex paint provided by the invention can be coated on a wall surface or wood, and the paint film has the advantages of being weak in smell, low in VOC (volatile organic compound), good in covering power, good in adhesion power, resistant to scrub and the like, and can effectively kill the harmful bacteria contacted with the painted wall surface in a room simultaneously; and moreover, the latex paint is low in cost, good in construction performance and great in environmental protection performance, and is mainly applied to decoration and protection for the surfaces of wall body, wood, etc.

Description

technical field [0001] The invention relates to the field of functional environmental protection coatings, in particular to an antibacterial latex paint containing natural jade powder and a preparation method thereof.
