Abstract

The invention discloses a packaging box adhesive. The packaging box adhesive contains the following components in parts by weight: 30-50 parts of epoxy resin, 30-50 parts of maleic resin, 30-50 partsof 2-imidazolidone, 30-50 parts of an ethylene-acetate copolymer, 10-20 parts of butyl rubber, 20-40 parts of epoxidized soybean oil, 15-30 parts of a castor oil hydrogenated mixture, 10-20 parts of boiled wood oil, 8-12 parts of tripropargyl trimellitate, 8-12 parts of a water-soluble polyethylene acetylene alcohol wax, 8-12 parts of isopropanol, 8-12 parts of silicon resin, 0.8-1.2 parts of an antioxidant, 1-3 parts of a tackifier and 2-20 parts of deionized water. By utilizing the epoxy resin, the high temperature resistance and adhesion property of the adhesive can be improved, meanwhile,the prepared adhesive is non-toxic and harmless, and a water-glue separation phenomenon is unlikely to occur; and the preparation method is simple, low in process condition and stable in product quality, a paper board obtained through adhesion is high in compressive resistance and strong in puncture resistance, and the quality of a product packaging box can be guaranteed. The packaging box adhesive has the characteristics of strong adhesion force, compressive resistance, moisture resistance and high temperature resistance.

Description

technical field [0001] The invention relates to a packaging box adhesive and a preparation method thereof, belonging to the technical field of carton preparation. Background technique [0002] Among all kinds of packaging for industrial products, packing boxes have become the mainstream of the packaging industry, because they are light in weight, foldable, low in cost, environmentally friendly, easy to change in specifications, can be printed with high quality, and can be used as renewable materials after recycling. Resources, therefore, are used more and more widely. Adhesive is an essential material for packaging box enterprises, 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, this type of adhesive has weak cohesive force, poor compression resistance, moisture resistance and high temperature resistance, so the quality of the produced packaging box products cannot be...
