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 discloses an environment-friendly white latex. The white latex comprises the following components in parts by weight: 700-1050 parts of polyvinyl acetate, 300-350 parts of vinyl acetate, 120-145 parts of polyvinyl alcohol, 60-100 parts of dibutyl phthalate, 20-40 parts of diethylene glycol dibenzoate, 10-15 parts of octanol, 30-45 parts of isopropanol, 10-25 parts of allyl methacrylate, 5-10 parts of ethylene glycol dimethacrylate, 3-7 parts of toluene diisocynate, 35-50 parts of sodium bicarbonate, 1400-1500 parts of water, 40-50 parts of emulsifier, 5-10 parts of initiator, 20-32 parts of hydroxymethyl acrylamide, 10-15 parts of waxy corn starch and 2-7 parts of sodium hypochlorite. By adopting the white latex, the environmental protection property of the product is fundamentally improved, the indexes such as the thermal stability, the initial drying time, the hydrolytic resistance, the bonding strength and the curing time are excellent and the comprehensive performance is superior.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environmentally friendly white latex. Background technique [0002] At present, the threshold industry of doors and windows is relatively low, and the competition in the industry is relatively chaotic. In order to improve product quality and market competitiveness, continuous improvement is required. High-grade energy-saving wooden doors and windows widely used in building exterior windows include: pure wood doors and windows, aluminum-clad wood 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 climate conditions in the south because the outer side is made of heat-insulating aluminum alloy profiles and the inner side is made of wood decorative profiles. At present, the structure of wood-aluminum composite doors and windows processed and produced...
