Abstract

The invention discloses external wall elastic emulsion with an antistatic effect and a method for preparing the external wall elastic emulsion. The external wall elastic emulsion comprises, by weight,90-120 parts of deionized water, 10-30 parts of iso-octyl acrylate, 60-80 parts of butyl acrylate, 20-35 parts of styrene, 5-15 parts of methyl methacrylate, 0.1-2 parts of acrylic acid, 0.1-1.5 parts of methacrylic acid, 0.1-1 part of acrylamide, 0-0.5 part of methacrylamide, 0-0.5 part of hydroxyethyl acrylate, 3-10 parts of acrylonitrile, 0.5-3 parts of acid anhydride functional monomers, 0.5-4 parts of diethanolamine, 0.1-3 parts of modified organophosphate high polymers, 1-8 parts of emulsifiers, 0.1-5 parts of initiators and 0.3-4.5 parts of ammonia water. The external wall elastic emulsion and the method have the advantages that the antistatic effect can be realized by the external wall elastic emulsion, the external wall elastic emulsion is excellent in stain resistance, and the excellent normal-temperature and low-temperature elasticity of the external wall elastic emulsion can be kept.

Description

technical field [0001] The invention relates to an exterior wall elastic emulsion with antistatic effect and a preparation method thereof, belonging to the technical field of latex paint. Background technique [0002] With the rapid growth of my country's economy, environmental pollution is also getting heavier, and various dusts and oily smog in the atmosphere are increasing. A considerable part of the exterior wall latex paint film loses its aesthetics and decoration due to the dirty surface. The service life of exterior wall latex paint is closely related to its stain resistance, and the quality of stain resistance has become the main obstacle for the application of exterior wall latex paint. At present, the adhesion pollution of exterior wall latex paint can be divided into two types: one is adhesion pollution; the other is inhalation pollution. Adhesive pollution means that pollutants are only physically adsorbed on the surface of the paint film; inhalation pollution m...
