Method for preparing multifunctional inner wall paint

Abstract

A preparation method for multifunctional interior wall coating material comprises the following steps: nanometer zinc oxide, titanium dioxide and silicon dioxide are weighed and put into a mixing tank to be stirred; dispersing agent which is weighed and is added into water to be mixed uniformly is sprinkled into a mixing tank containing nanometer powder to be evenly mixed with the nanometer components and is under closed standing 6 hours to 7 hours for further use; water, nanometer components, sodium hexametaphosphate and dispersing agent are added into a dispersing kettle in turn to be stirred at high speed for 20 minutes till the materials are fully dispersed; then, stirring speed is slowed down and superfine calcium carbonate powder, titanium pigment wollastonite powder, talcum powder, preservative, light ethyl cellulose and antifoaming agent are added in turn to be stirred at high speed for 60 minutes till the materials are fully dispersed; and then, stirring speed is slowed down again and pure acrylic emulsion, antifoaming agent, film-forming auxiliary agent, rheological agent and propylene glycol are added in turn to be stirred slowly; finally, coating material viscosity is adjusted through thickening agent, and finished product can be obtained after canning. The invention has the advantages that: the invention guarantees full dispersing of the nanometer components; meanwhile, the coating material possesses super-strong scrubbing resistance, weathering resistance and antibacterial performance and self-cleaning.

Description

technical field [0001] The invention relates to a preparation method of a multifunctional interior wall paint. Background technique [0002] Most of the interior wall coatings still have weak coatings, weak adhesion, easy peeling off coatings, poor scrubbing resistance, poor stain resistance, and excessive harmful substances. Adding nano-antibacterial powder and nano-silicon-based oxides to prepare the interior wall coating process cannot ensure that the nano-components are fully dispersed, and the due effect of the nano-components is not fully exerted. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned defective, a kind of preparation method of multifunctional interior wall paint is provided. [0004] The technical solution of the present invention is: a preparation method of multifunctional interior wall paint, characterized in that: pure acrylic emulsion 15-40; water 10-30; sodium hexametaphosphate 0.10-0.8; dispersan...
