Abstract

The invention discloses a corrugated carton adhesive which is prepared from the following raw materials in parts by weight: 45-55 parts of water, 28-34 parts of sweet potato powder, 12-16 parts of calcium carbonate, 2-3 parts of hydrochloric acid, 3-4 parts of meerschaum powder, 0.12-0.16 part of naphthalene sulfonate formaldehyde condensate, 0.15-0.18 part of sodium carboxymethyl cellulose and 0.10-0.12 part of white granulated sugar. The corrugated carton adhesive is prepared from the following steps: pouring water into a container, and regulating the water temperature to 56-64 DEG C; adding the sweet potato powder, and stirring to a viscous state; adding the calcium carbonate, and stirring for 15-18 minutes; adding the hydrochloric acid, and stirring for 6-8 minutes; and adding the meerschaum powder, naphthalene sulfonate formaldehyde condensate, sodium carboxymethyl cellulose and white granulated sugar, stirring uniformly, standing and cooling. The corrugated carton adhesive has the advantages of high adhesive capacity, high safety and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an adhesive for corrugated 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, which increases chemical pollution and needs 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 corrugated box adhesive, which has strong adhesiv...
