Abstract
The invention discloses a low-temperature hot-seal adhesive, which consists of the following raw materials in percentage by weight: 10 to 30 percent of main resin, 5 to 15 percent of auxiliary resin, 0.2 to 3 percent of plasticizer, 0.2 to 1 percent of surface modifier and 60 to 80 percent of solvent. The main resin is one or two of a polyester resin, a plastic polyurethane resin and a plastic acrylic resin with the molecular size of between 15,000 and 25,000; and the auxiliary resin is one of a vinyl chloride copolymer resin, a plastic polyurethane resin and an epoxy resin with the molecular size of between 10,000 and 20,000. The low-temperature hot-seal adhesive has the advantages that: 1, the adhesive has low-temperature hot-seal property, and the hot-seal strength is not lower than that of a common hot-seal adhesive for an aluminum foil; and 2, the adhesive has hot-seal diversification, can seal PVC, PC and PS sheets, and meets the requirement on hot-seal strength.
