Nano-barite powder modified compound adhesive for packaging

Abstract

The invention discloses a nano-barite powder modified compound 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 ferrocene, 8-12 parts of epichlorohydrin rubber H75, 5-8 parts of nitrile rubber N220S, 2-3 parts of zinc oxide, 10-15 parts of nano-barite powder, and the like. The adhesive is excellent in heat resistance 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 a composite packaging adhesive modified by nano barite powder. Background technique [0002] Composite packaging adhesives have received more and more attention in the rapid development of the packaging industry today, and their performance and quality directly affect packaging and quality. At present, composite packaging adhesives generally have poor heat resistance and poor cold resistance. Good, 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 composite packaging adhesive was produced by improving the formula. Contents of the invention [0003] The purpose of the present invention is to provide a composite packaging adhesive modified by nano barite powder with good high and low temperature resistance, high bonding strength and good storage stability. [0004] Th...
