Watersoluble pure acrylic emulsion for construction and method of producing the same

Abstract

The invention discloses aqueous building pure acrylic emulsion and a preparation method thereof, which belongs to the technical field of paint and is improved based on the prior art. The emulsion is synthesized with the materials by the following weight percent: 65 to 75 percent of de-ionized water; 10 to 15 percent of methyl methacrylate; 10 to 20 percent of butyl acrylate; 1 to 5 percent of methacrylic acid; 0.4 to 1 percent of OP-10; 0.1 to 0.5 percent of sodium dodecyl benzene sulfonate; 0.1 to 0.6 percent of potassium persulfate; 0.1 to 0.5 percent of sodium bicarbonate; 0.1 to 0.5 percent of reactive emulsifying agent; and 0.1 to 0.2 percent of ammonia. The aqueous building pure acrylic emulsion has the advantages of acid resistance, alkali resistance, excellent imperviousness, excellent low temperature flexibility, weatherability and ageing resistance, proper viscosity of pure acrylic emulsion, high stability, simple synthetic process, low price, no environmental pollution and meeting the technical requirement of aqueous building pure acrylic emulsion, thus being very promising in application in market.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a water-based architectural pure acrylic emulsion and a preparation method thereof. Background technique [0002] Pure acrylic emulsion has been developed and produced at home and abroad for a long time, but compared with the actual application requirements of pure acrylic emulsion, there are still some problems, mainly the minimum film forming temperature is too high, and the rheology of the emulsion, especially the viscosity, cannot be effectively adjusted. In order to solve the problems existing in the existing pure acrylic emulsion and develop a pure acrylic emulsion for construction with excellent performance, it is a hot topic of research by researchers at home and abroad. The traditional pure acrylic emulsion is mainly formed by the copolymerization of methyl methacrylate, butyl acrylate and a small amount of acrylic acid. The pure acrylic emulsion formed by the poly...
