Abstract
The invention relates to a preparation method of a water-soluble polishing varnish liquid, which comprises the following two steps: firstly synthesizing polyvinyl acetate varnish liquid by utilizing vinyl acetate, polyvinyl alcohol, dibutyl phthalate, ammonium persulfate, alkylphenol ethoxylate, sodium bicarbonate and water; and then preparing the water-soluble polishing varnish liquid from the polyvinyl acetate varnish liquid, titanium dioxide, talcum powder, carboxymethyl cellulose, sodium polymet, sodium nitrite, phenylmercuric acetate, sodium hexametaphosphate and water. The water-soluble polishing varnish liquid has favorable adhesion to the surfaces of metal, plastic, woodware and the like; the varnish film has good water resistance, brushing resistance, wear resistance and better covering power after being dried; and the varnish film is clear and clean, can maintain the full and excellent effect for a long time, and takes water in stead of organic solvent which is expensive, toxic and smelly and can cause environmental pollution as the solvent, thereby being a green environment-friendly product. The invention is applicable to coating and polishing of the surfaces of the metal, the plastic, the woodware and the like in houses and public buildings.
