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

[0011] A high-strength waterproof adhesive, made of the following raw materials in parts by weight (kg): E-44 epoxy resin 10, diethylenetriamine 3, polystyrene 4, coumarone 4, titanium dioxide 2, acrylic acid 4, ethyl Glycol ether acetate 5, butylene glycol 4, tert-butyl peroxybenzoate 2, attapulgite powder 4, silane coupling agent KH560 2, morpholine 1, acetone 17, ethyl acetate 8.

[0012] The preparation method of described high-strength waterproof adhesive comprises the following steps:

[0013] (1) Add polystyrene into ethyl acetate, heat to dissolve, then add acrylic acid, ethylene glycol ether acetate, coumarone, stir evenly, then add silane coupling agent KH560, and stir for 1-2 hours;

[0014] (2) Combine and mix other remaining ingredients, stir and react for 40-60 minutes;

[0015] (3) Mix steps (1) and (2), heat to 60-70°C, stir and react for 2-3 hours to obtain the product.

[0016] The adhesive prepared by the invention is tested: after 4 hours, the bonding str...

Abstract

The invention discloses a high-strength waterproof adhesive. The high-strength waterproof adhesive is prepared from the following materials in parts by weight: 10-12 parts of E-44 epoxy resin, 3-4 parts of diethylenetriamine, 3-4 parts of polystyrene, 3-4 parts of coumarone, 2-3 parts of titanium dioxide, 3-4 parts of acrylic acid, 4-5 parts of ethylene glycol monoethyl ether acetate, 3-4 parts of butanediol, 2-3 parts of tert-butyl peroxybenzoate, 4-5 parts of attapulgite powder, 2-3 parts of silane coupling agent KH560, 1-2 parts of morpholine, 15-17 parts of acetone and 8-10 parts of ethyl acetate. The high-strength water-absorbing adhesive disclosed by the invention is simple in material, low in price, high in adhesion strength and long in service life.

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 high-strength w...
