Metal adhesive glue used for high temperature

Abstract

The invention application discloses metal adhesive glue used for high temperature. The metal adhesive glue consists of the following components in parts by weight: 83 to 106 parts of polyvinyl acetate, 5 to 10 parts of volcanic, 0.5 to 0.8 parts of methylhexahydrophthalic anhydride, 41 to 53 parts of vinyl acetate, 25 to 35 parts of cycloaliphatic epoxide resin, 0.2 to 0.4 parts of antioxygen and 0.1 to 0.3 parts of accelerant, wherein the accelerant is prepared from the composition of 4 parts to 8 parts of Iodonitrotetrazolium and 15 parts to 23 parts of ethylene glycol solution. As an epoxy group of the cycloaliphatic epoxide resin is directly connected onto an alicyclic ring, and a compact rigid molecular structure can be formed, the heat stability of the glue can be enhanced; furthermore, by performing reasonable mass fraction preparation on the polyvinyl acetate and the vinyl acetate, the content of free formaldehyde in the scheme is reduced; as the volcanic is of a porous structure, molecules of the volcanic are compact and porous, have very powerful adsorption capacity, and are capable of adsorbing part of hazardous substances, therefore the environmental protective performance of the formula of the metal adhesive glue is further improved.

Description

technical field [0001] The invention relates to the field of decoration, in particular to a metal bonding glue used at high temperature. Background technique [0002] Aluminum alloy is usually used as the preparation material in the existing doors and windows, and the connection method of the steel plates is as follows: Among the two adjacent steel plates, one of the steel plates is provided with a slot, and the other steel plate is provided with a buckle that matches the slot. The steel plates are connected and fixed through the cooperation of slots and buckles; in order to further enhance the firmness of the fixation, glue is usually applied between adjacent steel plates; windows must withstand high temperature and rain erosion during use, especially in summer , the maximum temperature can reach 40°C, and the steel plate releases heat quickly, so that the glue can withstand a temperature of 60°C-70°C, while the existing glue will open after 5-6 months of use. Therefore, w...
