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 a composition for reinforcing binding power and use thereof. The composition for reinforcing binding power comprises the following components in parts by weight: 10-25 parts of allyl methacrylate, 5-10 parts of glycol dimethacrylate and 3-7 parts of toluene diisocynate. The invention further relates to use of the composition for reinforcing binding power in preparation of glue for connecting wood components. The composition for reinforcing binding power provided by the invention can be used for greatly improving the comprehensive performance of the glue for connecting wood components and ensuring that the glue has excellent performance and excellent comprehensive performance on such indexes as thermal stability, initial drying time, water resistance, bonding strength and curing time.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a composition for enhancing adhesion and its application. 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 proces...
