Calcium sulfate crystal whisker modified adhesive for packaging

Abstract

The invention discloses a calcium sulfate crystal whisker modified adhesive for packaging. The adhesive is prepared from the following raw materials in parts by weight: 100-120 parts of styrene, 100-150 parts of ethyl acetate, 20-25 parts of duprene rubber CR121, 15-20 parts of xylene, 1-2 parts of 4,4'-diphenyl methane diisocyanate, 8-12 parts of polyisobutylene, 2-3 parts of (3-aminopropyl)trimethoxysilane, 2-3 parts of polytetramethylene ether glycol, 3-5 parts of SG-2 PVC (polyvinyl chloride) resin, 1-2 parts of ferrocenem, 10-15 parts of styrene-butadiene rubber 1502, 5-8 parts of butyl rubber BBK232, 2-3 parts of zinc oxide, 2-3 parts of magnesium oxide, 20-25 parts of calcium sulfate crystal whisker, 10-15 parts of silica flour, and the like. The adhesive is excellent in heat resistance and cold resistance, high in cohesive strength, water-resistant, moisture-proof, good in storage stability, good in environment friendliness, good in using effect and convenient.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for packaging modified by calcium sulfate whiskers. Background technique [0002] Packaging adhesives are produced and developed on the basis of the rapid development of the packaging industry. The performance and quality of packaging adhesives directly affect the packaging effect and quality. At present, packaging adhesives generally have poor heat resistance. Poor, poor cold resistance, poor storage stability. In order to overcome the shortcomings of traditional adhesives such as poor heat resistance, poor cold resistance, and poor storage stability, a new type of packaging adhesive is produced by improving the formula. Contents of the invention [0003] The object of the present invention is to provide a calcium sulfate whisker-modified neoprene adhesive with good temperature resistance, good wear resistance, high bonding strength and good storage stability. [0004] The technica...
