Abstract

The invention discloses an easy-to-coat carton adhesive. The easy-to-coat carton adhesive is prepared from the following raw materials in parts by weight: 100-120 parts of water, 20-30 parts of corn starch, 10-15 parts of calcium carbonate, 2-3 parts of alum, 2-3 parts of light magnesium oxide, 0.42-0.46 part of aluminum sulfate, 0.36-0.38 part of polyvinyl alcohol, 1-2 parts of sodium bicarbonate, 0.7-0.8 part of potassium permanganate and 0.6-0.8 part of borax. The easy-to-coat carton adhesive is prepared according to the following steps: pouring water into a container and adjusting water temperature to 56-64 DEG C; pouring corn starch into the water, continuously stirring to a viscous state, then adding calcium carbonate and potassium permanganate, and stirring for 15-18min to obtain an emulsion A; and adding alum and light magnesium oxide into the emulsion A, stirring for 6-8min, then adding aluminum sulfate, polyvinyl alcohol and sodium bicarbonate, uniformly stirring, then adding borax, stirring for 20-25min, standing and cooling. The easy-to-coat carton adhesive disclosed by the invention is strong in adhesive capacity and easy to coat, and can improve the compressive strength and flexural strength of carbons.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an easy-to-coat carton adhesive. Background technique [0002] Adhesive is an essential material for carton companies, and it is mainly used in the compounding process of face paper or cardboard. At present, starch glue is mainly used for the bonding of cardboard. However, due to the weak cohesive force of this type of adhesive, poor compression resistance and moisture resistance, the quality of products at the production site cannot be guaranteed. In the prior art, after the adhesive is used, the appearance of the carton is not smooth enough, and the compressive and flexural strengths are unsatisfactory, which needs to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an easy-to-coat carton adhesive, which has strong adhesive ability, is easy to coat, and can improve the compres...
