The vinyl acetate used in this glue is highly toxic and not environmentally friendly
[0007] 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
[0008] 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 high-strength glue for connection of wood window members. The high-strength glue comprises the following ingredients (by weight): 950 parts of polyvinyl acetate, 335 parts of vinyl acetate, 135 parts of polyvinyl alcohol, 90 parts of dibutyl phthalate, 35 parts of diethylene glycol dibenzoate, 14 parts of octanol, 40 parts of isopropanol, 22 parts of allyl methacrylate, 9 parts of glycol dimethacrylate, 6 parts of toluene diisocyanate, 45 parts of sodium bicarbonate, 1,480 parts of water, 48 parts of sodium dodecyl benzene sulfonate as an emulsifier, and 9 parts of potassium persulphate as an initiator. Content of vinyl acetate in the high-strength glue for connection of wood window members is greatly reduced, and there is no need to use solvents such as formaldehyde, etc. Thus, environment protection of the product is fundamentally enhanced. Meanwhile, the glue provided by the invention has excellent performance in indexes such as thermal stability, initial drying time, water resistance, bonding strength and curing time, etc., has superior comprehensive performance, and can meet strict requirements of high-end energy-saving wood door and window quality.

Description

[0001] This application is a divisional application with application number 201510045040.2, application date January 28, 2015, and invention name "high-strength glue". technical field [0002] The invention relates to the technical field of building materials, in particular to a high-strength glue for connecting wooden window parts. Background technique [0003] 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...
