Abstract

The invention discloses a water-resistant quick-drying carton adhesive which is prepared from the following raw materials: water, modified starch, nano meerschaum powder, vinyl-acetate-base emulsion, potassium permanganate, sodium hydroxide, alum, borax and a reinforcing agent. The water-resistant quick-drying carton adhesive is prepared by the following steps: adding the modified starch and water, mixing, adding the potassium permanganate, sufficiently reacting at normal temperature for 80-120 minutes to gelatinize starch; adding the vinyl-acetate-base emulsion into the gelatinization product to terminate gelatinization; adding the sodium hydroxide and alum into the viscous solution, and stirring for 15-18 minutes; and adding the nano meerschaum powder, borax and reinforcing agent into the obtained solution, stirring uniformly, and cooling the solution by standing, thereby obtaining the adhesive.

Description

technical field [0001] The invention belongs to the technical field of carton production, in particular to a water-resistant and quick-drying carton adhesive. Background technique [0002] At present, the quality requirements for paper packaging products such as household appliances, precision electronic and electromechanical products, food and medicine are getting higher and higher. Ordinary paper packaging boxes, wood packaging, and EPS packaging can no longer adapt to the market and customers due to the quality, grade and environmental protection factors of packaging. It does not meet the environmental protection requirements of the country, the United States, Japan, South Korea, the European Union and other countries for green packaging. [0003] The demand for paper packaging in our province (with Hefei as the center) and in parts of the surrounding provinces and cities such as Jiangsu, Zhejiang, and Shanghai exceeds 10 billion yuan, and it grows at an annual rate of 25...
