Abstract

The invention discloses a pressure-sensitive adhesive for metals and a preparation method thereof. The pressure-sensitive adhesive for metals comprises the following components in parts by weight: 60-70 parts of polyisobutylene rubber, 10-20 parts of soft butadiene styrene rubber, 40-50 parts of rubber smoked sheet, 0.5-2 parts of stearic acid, 0.5-2 parts of anti-aging agent, 0.5-2 parts of accelerator, 10-20 parts of tert-butyl phenol-formaldehyde resin and 3-8 parts of chlorosulfonated polyethylene. The preparation method comprises the following steps: mixing and heating the components to 70-80 DEG C, keeping the temperature for 30-60 minutes while stirring, and cooling to room temperature. The performance test indicates that the holding power of the pressure-sensitive adhesive for metals is more than 8 hours, the stripping force is greater than 12N, and thus, the pressure-sensitive adhesive for metals is much superior to the commercially available common organic silicon pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to an adhesive for metal, in particular to a pressure-sensitive adhesive for metal and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesives are referred to as pressure-sensitive adhesives for short. They are adhesive at room temperature and can be bonded with a little pressure. Pressure-sensitive adhesives and their products have developed into an independent branch of adhesives. There are two types of pressure-sensitive adhesives: rubber type and resin type. The rubber type can be natural rubber or synthetic rubber, and the largest amount is natural rubber. Resin-type acrylate pressure-sensitive adhesives are the most important. In terms of form, pressure sensitive adhesives are divided into solvent type, emulsion type, hot melt type and liquid curing type. The output of solvent-based pressure-sensitive adhesives is gradually decreasing due to high solvent prices, toxicity and flammability, ...
