Abstract

The invention discloses a nano modified polyvinyl acetate-acrylic acid building exterior wall emulsion paint, which comprises the following ingredients by weight: 300-400 parts of nano sol modified vinyl acetate-acrylic acid emulsion, 3-6 parts of hydroxyethyl cellulose, 2-6 parts of sodium dodecyl sulfate, 10-20 parts of sodium silicate, 20-30 parts of glycol, 1-3 parts of dimethicone, 200-300 parts of rutile, 60-80 parts of zinc oxide, 10-20 parts of sodium potassium aluminosilicate, 100-120 parts of powdered steatile, 30-50 parts of kaolin and 300-400 parts of water. By using the characteristic of nano silica sol, the paint performance and latex film performance of the paint can be increased based on keeping the size and distribution of particle size of the emulsion.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a nano-modified polyvinyl acetate-acrylic acid latex paint for building exterior walls. Background technique [0002] Paint is a flowable or soluble mixture, which is painted on the surface of the object, can be well bonded with the base material and form a complete and tough protective film, latex paint is a kind of paint, it is based on synthetic resin emulsion The base material uses water as the dispersion medium, adds pigments, fillers and additives, and is made into latex-like substances through a certain process. The functions of latex paint can be summarized into three aspects: protection, decoration and special functions. Latex paint contains 4 basic substances: film-forming substances, pigments and fillers, solvents, and additives. [0003] Latex paint has the characteristics of fast drying speed, good alkali resistance, soft color, and hard paint film,...
