Problems solved by technology

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 adhesive, the glue includes: polyvinyl alcohol PVA, vinyl acetate VAC, acrylic acid AA, acrylamide AM, ammonium persulfate , anionic emulsifier A-102, alkyl polyoxyethylene ether LCN-287 nonionic emulsifier; corn starch, transparent powder, plasticizer, diethylene glycol dibenzoate DEDB, preservative KSG-201, hydroxide Sodium, 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 comprehensive performance in terms of use effect and cannot meet the stringent demands of the market.

Abstract

The invention provides a composite initiator and use of the composite initiator. The composite initiator comprises the following components in parts by weight: 3-4 parts of potassium persulfate, 1-2 parts of ammonium persulfate, 2-4 parts of sodium hydrogen sulfite, 1-2 parts of sodium persulfate and 1-3 parts of kaoline. The invention also relates to use of the composite initiator in preparation of an adhesive. The adhesive prepared by using the composite initiator is high in environmental friendliness, high in heat stability, quick in initial drying time, high in waterproof performance, high in bonding strength, quick in curing time and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of initiators, in particular to a composite initiator 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 processed and produced in th...
