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

[0010] Adhesive for wrapping paper, made of the following raw materials in parts by weight (kg): polyvinyl alcohol 5, hydroxymethyl cellulose 2, starch 4, silicon acrylic emulsion 7, Silane coupling agent KH5502, Chitosan 4, styrene-acrylic emulsion 8, white latex 2, morpholine 1, ammonium persulfate 2, water 90.

[0011] The preparation method of the wrapping paper adhesive includes the following steps: (1), adding polyvinyl alcohol into water, heating to 85-95°C, then adding starch, stirring to dissolve, then adding chitosan and morpholine, and stirring for 30- 45 minutes, then add ammonium persulfate, stirring and reacting for 45-60 minutes;

[0012] (2) Mix other remaining materials;

[0013] (3) Mix the materials in step (1) and (2), heat to 85-90°C, stir and react for 1-2 hours.

[0014] The adhesive prepared by the invention is tested: after 4 hours, the bonding strength reaches 6Mpa, and the water resistance is good. After bonding, soak in water at 40°C for 2 hours...

Abstract

The invention relates to a packaging paper adhesive. The packaging paper adhesive is characterized by being prepared from the following raw materials: 4-5 parts of polyvinyl alcohol, 2-3 parts of hydroxymethyl cellulose, 4-5 parts of starch, 6-7 parts of silicone acrylic emulsion, 2-3 parts of silane coupling agent KH550, 3-4 parts of chitosan, 8-9 parts of styrene-acrylic emulsion, 2-3 parts of white emulsion, 1-2 parts of morpholine, 1-2 parts of ammonium persulfate and 90-100 parts of water. Compared with the prior art, the packaging paper adhesive has the beneficial effects of good adhesive property, high curing speed, no any chemical residue 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 wrapping paper ...
