Abstract

The invention discloses a modified pure acrylic emulsion and a preparation method thereof. The emulsion comprises the following components by mass percent: 42-56% of water, 1-3% of propylene glycol, 20-30% of methyl methacrylate, 15-25% of butyl acrylate, 0.8-1.2% of methacrylic acid, 1.0-1.4% of emulsifier OP-10, 1.2-1.6% of sodium dodecyl benzene sulfonate, 0.4-0.6% of sodium bicarbonate, 0.4-0.6% of potassium persulfate, 0.23-0.66% of nano ZrO2, 0.5-1.2% of ammonia water and 0.04-0.17% of mixture of silane coupling agent and oleic acid (5:1). The nano ZrO2 modified pure acrylic emulsion has the advantages of environment friendliness, aging resistance, washability, water resistance, alkali resistance, good emulsion stability, high film hardness and the like.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and relates to a coating base material, in particular to a pure acrylic emulsion and a preparation method thereof. Background technique [0002] As a base material, pure acrylic emulsion is widely used in the fields of exterior wall latex paint, color paint, high-grade interior wall paint, high-grade real stone paint, and exterior wall cement paint. In recent years, the research on the preparation of pure acrylic emulsion at home and abroad has achieved certain results, but there are still problems to be solved. Pure acrylic emulsion has defects such as low coating film hardness, high film forming temperature, low emulsion stability, aging resistance, scrub resistance, water resistance, and alkali resistance, which affect the application of pure acrylic emulsion. [0003] Through research and experiments, it was found that the use of silane coupling agent and oleic acid mixed modi...
