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 preparation method of high-strength glue. The method comprises the following steps: selecting water and polyvinyl alcohol; mixing water with polyvinyl alcohol; rising the temperature; selecting an emulsifying agent; adding the emulsifying agent and the surplus water into the solution under a stirring condition; slowly adding vinyl acetate and an initiating agent; rising the temperature and preserving the heat; cooling; then adding the surplus vinyl acetate and the surplus initiating agent; adding the emulsifying agent and polyvinyl acetate; adding sodium hydrogen carbonate, phthalic acid dibutyl ester, diethylene glycol dibenzoate, octanol and isopropanol; adding the surplus emulsifying agent, methacrylic acid allyl ester, ethyldiol methacrylate and toluene diisocynate to obtain the glue. In the glue prepared by using the method, the content of vinyl acetate is greatly reduced, so that the environmental protection performance of a product is radically improved; moreover, the glue is high in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a preparation method of high-strength glue. 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 produ...
