Abstract

The invention discloses a composite board adhesive for a carton. The composite board adhesive for the carton is prepared from the following raw materials in parts by weight: 65-75 parts of water, 18-24 parts of corn starch, 2-6 parts of calcium carbonate, 1-2 parts of sodium hydroxide, 3-4 parts of sepiolite powder, 0.12-0.16 part of a naphthalenesulfonate formaldehyde condensation compound, 0.15-0.18 part of sodium carboxymethylcellulose, 0.40-0.52 part of bisphenol A epoxy vinyl ester resin, 0.20-0.24 part of acrylic vinyl ester resin and 0.82-0.96 part of hydroxyethyl cellulose. The adhesive is prepared by the following steps: uniformly mixing sodium hydroxide, part of water and part of corn starch; adding residual water and the corn starch into a container; after uniformly stirring, adding the sepiolite powder, the naphthalenesulfonate formaldehyde condensation compound, sodium carboxymethylcellulose, the bisphenol A epoxy vinyl ester resin, the acrylic vinyl ester resin and hydroxyethyl cellulose and uniformly stirring; and adding a backing material and calcium carbonate and uniformly stirring. The composite board adhesive for the carton disclosed by the invention is strong in adhesive capacity, stable in performance and long in storage period.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a composite cardboard adhesive for cartons. 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 need to be improved. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a composite cardboard adhesive for cartons, which has strong adhesive ability, st...
