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

Embodiment Construction

[0009] A corrugated cardboard box adhesive, made of the following raw materials in parts by weight (kg): 10 butyl acrylate, 1 tert-butyl peroxybenzoate, 40 ethyl acetate, 7 butadiene, 4 polyoxyethylene abietic acid , Acrylic acid 4, Acrylonitrile 2, Ethanol 10, Methyltriethoxysilane 4, Polyethylene glycol dimethacrylate 2, Morpholine 1, Urea 3, Polyisobutylene 3.

[0010] The preparation method of corrugated carton adhesive comprises the following steps:

[0011] (1) Add urea into ethanol and heat until dissolved; then add acrylic acid, acrylonitrile and methyltriethoxysilane, stir for 30-45 minutes, then add butadiene, and continue stirring for 30-45 minutes;

[0012] (2) Mix the materials in step (1) with other remaining ingredients, heat to 60-70°C, and stir for 1-2 hours to obtain.

[0013] The adhesive prepared by the invention is tested: after 4 hours, the bonding strength reaches 19Mpa, and the water resistance is good. After bonding, soak in water at 40°C for 2 hours...

Abstract

The invention relates to a corrugated carton bonding agent. The corrugated carton bonding agent is prepared from the following raw materials in parts by weight: 10-12 parts of butyl acrylate, 1-1.2 parts of tert-butyl peroxide, 40-45 parts of ethyl acetate, 5-7 parts of butadiene, 3-4 parts of polyoxyethylene rosin ester, 4-5 parts of acrylic acid, 1-2 parts of acrylonitrile, 10-12 parts of ethanol, 3-4 parts of methyl triethoxysilane, 2-3 parts of polyethylene glycol dimethacrylate, 1-2 parts of morpholine, 2-3 parts of urea and 3-4 parts of polyisobutene. The corrugated carton bonding agent is used for bonding corrugated cartons and has the advantages of high bonding strength, good waterproof performance, simple and convenient preparation process, good performance, no environmental pollution 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 a corrugated cart...
