Abstract

The invention is the antibacterial, waterproofing, anti-aging nanometer benzene-acrylic emulsion relating to a kind of constructing emulsion used for preparing inside and outside wall dope. The component proportions of the invention are: deionized water 42%, n-butyl acrylate (BA) 24.4%, styrene (St) 24%, non-ionic emulsifier (MS-01) 1.8%, nano-ZnO 1.8%, nano-TiO2 1.2%, anion emulsifier (DSB) 1%, N-methylolacrylamide (N-MAM) 1%, methylacrylic acid (MAA) 1%, tert-butyl hydroperoxide (TDHP) 0.6%, sodium formaldehydesulfoxylate (SFS) 0.6%, ammonium persulfate (APS) 0.4%, NaHCO3 0.2%, and AMP-95 0.2%. According to the said weight proportions, prepare the emulsion through pre-emulsifying, milling, and polymerizing at high temperature.

Description

technical field [0001] The present invention relates to a synthesis method of architectural emulsion, more specifically the present invention relates to a novel waterproof and antibacterial emulsion used for preparing interior and exterior wall coatings. Background technique [0002] At present, the emulsion used in the preparation of interior and exterior wall architectural coatings, its oily emulsion has good waterproof and stain resistance, but it is not environmentally friendly. Water-based emulsions are environmentally friendly, but have poor waterproof and anti-aging properties, and are not antibacterial. In view of this situation, we have developed this new type of emulsion that is environmentally friendly, waterproof, stain-resistant, antibacterial, and aging-resistant. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and the architectural paint prepared by using the emulsion not only has funct...
