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

The invention discloses an epoxy resin carton adhesive. The epoxy resin carton adhesive is characterized by being prepared from the following raw materials in parts by weight: 10-12 parts of E-42 epoxy resin, 3-4 parts of methylene bis-cyclohexaneamine, 4-5 parts of 2,4-toluene diisocynate, 2-3 parts of maleic anhydride, 40-45 parts of ethyl acetate, 3-4 parts of dibutyltin dilaurate, 5-6 parts of acrylic acid, 3-4 parts of butadiene, 4-5 parts of styrene, 6-8 parts of diglycol, 1-2 parts of morpholine, 4-5 parts of acetone, 4-5 parts of chloroform, 2-3 parts of cyclohexanone peroxide, 3-4 parts of neopentyl glycol, 1-2 parts of catechol, and 2-3 parts of polyisobutene. The epoxy resin carton adhesive disclosed by the invention is good in adhesive property, excellent in stretching performance, peel resistance and ageing resistance, high in adhesive strength, and better in the comprehensive performances of heat resistance, ageing resistance, and the like.

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 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. 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 ca...
