Abstract

The invention relates to a powerful metal adhesive. The powerful metal adhesive is prepared from the following components: chloroprene rubber, styrene, waterborne polyurethane resin, liquid paraffin, methylbenzene, dimethyl carbonate, propylene dichloride, methyl methacrylate, alkylphenol polyoxyethylene ether sodium sulfate and organic tin catalysts. Through experiments, the special waterborne polyurethane resin can be replaced, so that the adhesion properties such as viscosity and peeling strength and the like of the adhesive are greatly improved; the powerful metal adhesive has obvious effect and broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a strong metal adhesive. Background technique [0002] Metal adhesives are usually a strong adhesive glue with ethyl cyanoacrylate as the main component, and are mainly used for rapid bonding between various metals, plastics, rubber, jewelry, electronics and other products. As a kind of adhesive, metal adhesive needs to continuously improve its performance indicators such as viscosity and peel strength. In the existing technology, technical adhesives have strong odor and high toxicity, which can no longer meet the current demand for environmentally friendly adhesives. . Contents of the invention [0003] In order to solve the above problems, the present invention provides a strong metal adhesive. [0004] The present invention is realized through the following technical solutions: [0005] A strong metal adhesive, specifically prepared by the following ...
