Embodiment 1

[0021] Clean the polymerization kettle with a high-pressure hot water gun, apply Italian yellow (TS0301) 150g on the wall of the kettle with an electric spray valve, and wash the kettle with tap water after 20 minutes. Add 340KG of pure water and 1KG of PVA (5%) suspending agent into the still, stir and mix. Then put 50KG of methyl acrylate, 112KG of butyl acrylate, 30KG of acrylonitrile, 4KG of acrylic acid, 4KG of hydroxyethyl methacrylate, and 0.7KG of initiator azobisisobutyronitrile into the polymerization kettle. React at 72±5°C for half an hour, then react at 70±5°C for 1.5-2 hours, raise the temperature to 80±5°C and continue to keep warm for 1.5-2 hours, then add 0.4KG of water-based initiator ammonium persulfate and continue to keep warm for 0.5-1 hour . Unreacted monomer was removed in vacuo for 0.5 hours. Cool down to 40°C, dehydrate by centrifugation, and wash three times with 1000KG water. Dry to obtain 198KG of acrylic resin, and there is very little resin st...

Embodiment 2

[0023] Rinse the polymerization kettle with a high-pressure hot water gun, apply 100g of British Blue (HYF-03) to the wall of the kettle with an electric spray valve, and wash the kettle with tap water after 20 minutes. Add 300KG of pure water and 2KG of PVA (5%) suspending agent into the still, stir and mix. Then put 40KG of ethyl acrylate, 133KG of isobutyl acrylate, 20KG of acrylonitrile, 3KG of acrylic acid, 4KG of hydroxyethyl methacrylate, and 0.6KG of benzoyl peroxide as an initiator into the polymerization kettle. React at 75±5°C for half an hour, then react at 73±3°C for 1.5-2 hours, raise the temperature to 85-90°C and keep warm for 1.5-2 hours, then add 0.4KG of aqueous initiator potassium persulfate and keep warm for 1 hour. Unreacted monomer was removed in vacuo for 0.5 hours. Cool down to 40°C, dehydrate by centrifugation, and wash three times with 1000KG water. Dry to obtain 198KG of acrylic resin, and there is very little resin sticking to the wall of the ket...

Abstract

This invention discloses a method for preparing a waterproof acrylate coating agent. The object coated with the waterproof acrylate coating agent has such advantages as soft touching sense, high water resistance, high waterproof effect, and high film -forming performance, and high wind, rain, gigging and cold resistance. The generated waste gases can be incinerated in a catalytic incinerator, thus the waterproof acrylate coating agent is environmentally friendly.

Description

technical field [0001] The invention belongs to textile finishing technology, and more specifically relates to an acrylate coating waterproofing agent and a preparation method thereof. Background technique [0002] Most of the previous acrylate coating waterproofing agents used the suspension method, and because of the heat transfer factor, stainless steel steam was used to heat the polymerization kettle, so there were many small acrylate particles stuck to the polymerization kettle wall during the polymerization process, which affected the product quality and quality. Product yield. It also affects the heat transfer effect of the kettle, and sometimes even because of the poor heat transfer effect during the polymerization process, the product detonates or even explodes. Secondly, it is more difficult to clean the acrylate particles sticking to the wall of the kettle. Most of them are manually cleaned in the kettle, and it is difficult for the operators to endure such worki...
