Abstract

The invention relates to a high-grammage coated paper bonding weather-proofing sealant, belonging to the field of hot melt adhesive production. Existing paper bonding adhesives are low in initial adhesiveness. The high-grammage coated paper bonding weather-proofing sealant provided by the invention comprises the following components in parts by mass: 0.3-1 part of an antioxidant, 10-15 parts of paraffin, 1-2 parts of microcrystalline wax, 6-10 parts of Fischer-Tropsch wax, 5-10 parts of hydrogenated rosin, 5-10 parts of C9 petroleum resin, 15-25 parts of rosin resin, 15-25 parts of EVA 2825 and 17-22 parts of EVA 28800. The EVA 2825 with a melt index of 25 and a VA content of 28 and the EVA 28800 with a melt index of 800 and a VA content of 28 are taken as main materials, which are compatible with the tackifying resin and the antioxidant, and the microcrystalline wax, the C9 petroleum resin and the rosin resin are added simultaneously, so that the sealant has the advantages of high cohesive strength, strong adhesive force and stable performance.

Description

technical field [0001] The invention relates to a high grammage coated paper bonding weather-resistant adhesive, which belongs to the field of hot-melt adhesive production. Background technique [0002] With the continuous development of the economy and the improvement of humanistic accomplishment, more and more people like to read and collect books. Therefore, higher requirements are put forward for the quality of book binding. It is necessary to make the paper of books smooth and beautiful, and the bound books have Strong bond strength, books have a long storage time. This puts higher requirements on the bond strength, weather resistance and shelf life of our bookbinding hot melt adhesives. In 2016, major publishing houses across the country conducted strict quality inspections on major Xinhua printing factories. The performance of hot melt adhesives cannot meet the requirements. [0003] In view of the above deficiencies, it is necessary to develop a high grammage coate...
