Synthesizing method for confecting inner-outer wall coating water-proof stain-resistant latex

Abstract

The invention discloses a method for synthesizing the water resistance antibiotic emulsion of inner or exterior wall paint, which comprises the following steps: dissolving sodium carbonate decahydrate in the water; dissolving the ammonium peroxodisulfate with the water; dispersing the nanometer powder with the water; dissolving the tert-butyl hydroperoxide with the water; dissolving sodium formaldehyde sulfoxylate in the water; adding various emulsifier in the deionized water; getting preemulsion by adding butyl acrylate, ethyl acrylate, methyl methacrylate and N-methylol acrylamide and mixing; adding the nanometer material after adding the rest water, emulsifier and sodium carbonate decahydrate solution in the bottle and mixing; heating; adding the preemulsion and initiating agent solution; dropping the rest preemulsion and initiating agent solution after reacting; keeping the temperature; reducing the temperature; adding tert-butyl hydroperoxide solution; adding formaldehyde sodium sulphoxylate solution; proceeding with the reaction; reducing the temperature; adjusting pH value with smmonia water; stopping mixing; getting the material by filtering. The invention has the water resistance, the environmental protection, the age resistance and the antibiosis.

Description

technical field

[0001] The invention relates to a synthesis method for preparing a waterproof and stain-resistant emulsion for 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. Contents of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcoming, provide a kind of preparation method for the synthesis of waterproof and stain-resistant emulsion of interior and exterior wall paint

[0004] The technical solution of the present invention is: a synthetic method for preparing the waterproof and stain-resistant emulsion of interior and exterior wall coatings, which is characterized in that: 42% deionized water, 22% butyl ac...
