Problems solved by technology

Some adhesives will release free formaldehyde in the process of production and application, which is seriously harmful to the human body and the environment; some adhesives have poor water resistance and moisture resistance, are easy to absorb moisture in humid air, and have low bonding strength; Creep phenomenon occurs, which reduces the bonding strength, and it is easy to freeze when stored below -5°C, which damages the emulsion, thus greatly limiting its application

Abstract

An epoxy resin carton adhesive is characterized in that it is made of the following raw materials in parts by weight: E-42 epoxy resin 10-12, Methylenebicyclohexylamine 3-4 、 2,4-toluene diisocyanate 4-5, maleic anhydride 2-3, ethyl acetate 40-45, dibutyltin dilaurate 3-4, acrylic acid 5-6, butadiene 3-4, Styrene 4-5, diethylene glycol 6-8, morpholine 1-2, acetone 4-5, chloroform 4-5, cyclohexanone peroxide 2-3, neopentyl glycol 3-4, catechol 1 -2. Polyisobutylene 2-3; the present invention has good adhesive properties, excellent stretching, peeling resistance, and anti-aging properties. The adhesive not only has high bonding strength, but also has heat resistance and aging resistance, etc. The overall performance is also better.

Description

technical field [0001] The invention relates to a chemical material, more specifically to an adhesive. Background technique [0002] At present, there are many kinds of adhesives used in cartons, such as trialdehyde glue and white latex. Some adhesives will release free formaldehyde during production and application, which is seriously harmful to human body and environment; some adhesives have poor water resistance and moisture resistance, are easy to absorb moisture in humid air, and have low bonding strength; Creep phenomenon occurs, which reduces the bonding strength, and it is easy to freeze when stored below -5°C, which damages the emulsion, thus greatly limiting its application. It is necessary to develop new adhesives with high bonding strength, safety, environmental protection and good stability. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an epoxy resin carton adhesive and a...
