Abstract

A carton adhesive with a good waterproof effect is formed by, by weight, corn starch, potassium permanganate, borax, sodium hydroxide, a ketoaldehyde polyvinyl alcohol compound, a bridging agent, a water quality stabilizer, a catalyst, carboxymethylcellulose sodium, an antifoaming agent, a curing agent and deionized water. The weights of the waterproof carton adhesive are reasonably selected, and proper steps are adopted to blend, so the structure of the adhesive is improved, the fluidity and the permeability of the adhesive are enhanced, and the endophilicity of the adhesive with paper fibers is improved, thereby the adhesive has high adhesion strength, good waterproof property, good toughness of an adhesive film, and difficult appearing of the water-adhesive separation phenomenon; and the adhesive prepared in the invention is nontoxic and harmless, and has the advantages of simple process due to stirring being a main step in the whole blending process, low technological conditions, stable product quality, and large compressive resistance and strong puncturing resistance of cardboards obtained after adhering by using the adhesive.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a carton adhesive with good water resistance. 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, the pressure resistance and moisture resistance are poor, so the quality of the produced products cannot be guaranteed. In the prior art, there are other ingredients added to starch glue to improve its performance, but such added ingredients often contain ingredients that are irritating to the human body and increase chemical pollution, which needs to be improved, and its waterproof performance needs to be improved. Contents of the invention [0003] The present invention aims to provide a carton adhesive with good water resistance. ...
