Abstract

The invention discloses an anti-mildew carton adhesive, which is prepared from the following raw materials in parts by weight: 65-75 parts of water, 9-12 parts of rice starch, 22-30 parts of sticky rice starch, 12-16 parts of calcium carbonate, 1-2 parts of sodium hydroxide, 3-4 parts of epoxy resin, 0.12-0.16 part of a naphthalene sulfonate formaldehyde condensation compound, 1.5-1.8 parts of carboxymethyl cellulose, 0.3-0.5 part of borax, and 1.5-1.7 parts of a preservative. A preparation method comprises the following steps: pouring water into a container, and regulating the temperature of water to be 50-70DEG C; adding rice starch into water, then evenly stirring and adding sticky rice starch, and stirring to be thick, to obtain an emulsion A; adding calcium carbonate into the emulsion A, and stirring to obtain an emulsion B, wherein the stirring time lasts 10-20min; adding sodium hydroxide, epoxy resin, naphthalene sulfonate formaldehyde condensation compound, carboxymethyl cellulose, borax and preservatives into the emulsion B, evenly stirring, and then standing and cooling. The anti-mildew carton adhesive is strong in adhesion power and difficultly generates mildew.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a mildew-resistant 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, 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 mildew-proof carton adhesive, which has strong ad...
