Abstract

The invention discloses a water-resistant carton adhesive, which is prepared from the following raw materials in parts by weight: 75-85 parts of water, 20-24 parts of tapioca, 12-16 parts of calcium carbonate, 2-3 parts of a hydrochloric acid, 3-4 parts of sepiolite powder, 0.12-0.16 part of a napsylate-formaldehyde condensate, 0.15-0.18 part of carboxymethyl cellulose, 0.40-0.60 parts of borax, and 0.40-0.60 part of urea formaldehyde resin. The water-resistant carton adhesive is prepared through the following steps: pouring water into a container, and adjusting the temperature of the water to 56-64 DEG C; adding tapioca, and constantly stirring until the obtained product is sticky; adding calcium carbonate, and stirring for 15-18 min; adding a hydrochloric acid, and stirring for 6-8 min; and adding borax and urea formaldehyde resin, uniformly stirring, adding sepiolite powder, a napsylate-formaldehyde condensate and carboxymethyl cellulose, uniformly stirring, standing, and cooling, so that the water-resistant carton adhesive is obtained. The water-resistant carton adhesive disclosed by the invention is strong in adhesive capacity, and is safe, and environmental-friendly.

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 and poor compression resistance of this type of adhesive, the quality of the produced products cannot be guaranteed. At the same time, since the main components of starch glue include corn starch, water, and caustic soda, the waterproof ability is insufficient. Improvements are needed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a water-resistant carton adhesive with strong adhesive ability, safety and environmental protection. [0004] The invention proposes a water-resistant carton ...
