Embodiment Construction

[0005] 1. Its composition ratio (weight ratio): use 42% deionized water, 24% butyl acrylate (BA), 23.6% methyl methacrylate (MMA), 2% non-ionic emulsifier (MS- 01), 1.8% nano ZnO, 1.2% nano TIO 2 ,,, 1% anionic emulsifier (DSB), 1% N-methylolacrylamide (N-MAM), 1% methacrylic acid (MAA), 0.6% tert-butyl hydroperoxide (TDHP), 0.6% Sodium formaldehyde sulfoxylate (SFS), 0.4% ammonium persulfate (APS), 0.4% polymeric emulsifier (AMPS), 0.2% baking soda (sodium bicarbonate), 0.2% AMP-95.

[0006] 2. Production method

[0007] (1) Add baking soda to deionized water to dissolve (1 part of baking soda to 10 parts of water), dissolve 1 part of initiator ammonium persulfate to 15 parts of water, and mix nano-ZnO and nano-TIO 2 The powder is dispersed with 1 part to 10 parts of water at a high speed of 3000-4000 rpm for 1-2 hours, 1 part of tert-butyl hydroperoxide to 10 parts of water is dissolved, and 1 part of formaldehyde sodium sulfoxylate (SFS) is dissolved. In 10 parts of wate...

Abstract

The invention is the antibacterial, waterproofing, anti-aging nano pure-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%, methyl methacrylate (MMA) 23.6%, non-ionic emulsifier (MS-01) 2%, nano-ZnO 1.8%, nano-TiO2 1.2%, anion emulsifier (DSB) 1%, N-methylolacrylamide (N-MAM) 1%, acrylic acid (AA) 0.8%, tert-butyl hydroperoxide (TDHP) 0.6%, sodium formaldehydesulfoxylate (SFS) 0.6%, ammonium persulfate (APS) 0.4%, polymerizable emulsifier (AMPS) 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...
