Problems solved by technology

The vinyl acetate used in this glue is highly toxic and not environmentally friendly
[0006] Chinese invention patent application 201410004735.1 (public date: April 16, 2014) discloses an environmentally friendly white latex, the glue includes: polyvinyl alcohol PVA, vinyl acetate VAC, acrylic acid AA, acrylamide AM, persulfuric acid Ammonium, anionic emulsifier A-102, alkyl polyoxyethylene ether LCN-287 nonionic emulsifier; corn starch, transparent powder, plasticizer, diethylene glycol dibenzoate DEDB, preservative KSG-201, hydrogen Sodium oxide, and methanol; but this glue still uses toxic vinyl acetate, which has poor environmental performance
[0007] At the same time, the related glue disclosed in the prior art has poor overall performance in terms of use effect, and cannot yet meet the relevant requirements for the quality of high-grade energy-saving wooden doors and windows.

Abstract

The invention provides strong white latex. The strong white latex comprises the following components in parts by weight: 900 parts of polyvinyl acetate, 330 parts of vinyl acetate, 130 parts of polyvinyl alcohol, 85 parts of dibutyl phthalate, 30 parts diethylene glycol dibenzoate, 13 parts of octanol, 37 parts of isopropanol, 19 parts of allyl methacrylate, 8 parts of glycol dimethacrylate, 5 parts of toluene diisocynate, 41 parts of sodium bicarbonate, 1460 parts of water, 46 parts of an emulsifying agent, 8 parts of an initiator, 27 parts of hydroxymethyl acrylamide, 13 parts of waxy corn starch and 5 parts of sodium hypochlorite. The environmental-friendly performance of the strong white latex is fundamentally improved; meanwhile, the strong white latex has excellent representation on indexes of thermal stability, initial drying time, water resistance, bonding strength and curing time and has excellent overall performance.

Description

Technical field [0001] The invention relates to the technical field of chemical raw materials, in particular to a strong white latex. Background technique [0002] At present, the door and window industry is relatively low, and industry competition is chaotic. In order to improve product quality and market competitiveness, continuous improvement is needed. The high-grade energy-saving wooden doors and windows widely used in building exterior window projects include three types: pure wooden doors and windows, aluminum-clad wooden doors and windows, and wood-aluminum composite doors and windows. The wood-aluminum composite doors and windows are more suitable for the rainy, high temperature, and humid weather conditions in the south because of the heat-insulating aluminum alloy profile on the outside and the wooden decorative profile on the inside. At present, the structure of processing wood-aluminum composite doors and windows in the domestic market is unreasonable. The assembly ...
