Abstract

The invention is the synthesizing method of nano compound 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) 22%, methyl methacrylate (MMA) 22%, organosilicon monomer (ethylene triethoxy silicon hydride A-151) 4.1%, non-ionic emulsifier (OP-10) 1.5%, nano-SiO2 1.5%, nano-TiO2 1.2%, anion emulsifier (DSB) 1%, N-methylolacrylamide (N-MAM) 1%, methylacrylic acid (MAA) 1%, polymerizable emulsifier AMPS 0.5%, ammonia 0.5%, tert-butyl hydroperoxide (TDHP) 0.5úÑ, sodium formaldehydesulfoxylate (SFS) 0.5%, ammonium persulfate (APS) 0.4%, and NaHCO3 0.3%. According to the said weight proportions, prepare the emulsion through emulsifying, milling, drop adding 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 stain-resistant emulsion 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 poor in water and stain resistance. 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 disadvantages, and the architectural coating prepared by using the emulsion has various good properties. It is improved by adding na...
