Abstract

The invention discloses a water resistant carton adhesive which is prepared from the following raw materials in parts by weight: 65-75 parts of water, 28-34 parts of sweet potato powder, 12-16 parts of calcium carbonate, 1-2 parts of sodium hydroxide, 2-3 parts of keto-aldehyde polyvinyl alcohol compound, 3-4 parts of sepiolite powder, 1.2-1.6 parts of bridging agent, 0.15-0.18 part of sodium carboxymethyl cellulose, 0.10-0.12 part of water quality stabilizer and 0.26-0.36 parts of borax; the water resistant carton adhesive is prepared according to the following steps: pouring water into a container, regulating the temperature of the water to 33-45 DEG C, adding sodium hydroxide and uniformly stirring; then adding the sweet potato powder, and continuously stirring to be sticky; adding calcium carbonate and borax and stirring for 13-20 min; adding the water quality stabilizer and stirring for 5-10min; adding the sepiolite powder, the keto-aldehyde polyvinyl alcohol compound, the bridging agent and sodium carboxymethyl cellulose, uniformly stirring, standing and cooling. The water resistant carton adhesive disclosed by the invention has strong adhesive ability and good waterproof performance.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a water-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 water-resistant carton adhesive with strong adhesiv...
