Abstract

The invention discloses a low-cost rapid wireless binding hot melt adhesive and a preparation method thereof, and relates to the technical field of hot melt adhesives, the hot melt adhesive comprisesthe following components by weight: 35-55% of an olefin polymer, 1-8% of EVA resin, 2-10% of a reinforced rubber chain segment polymer, 30-55% of tackifying resin, 0-10% of microcrystalline wax, 3-10%of Fischer-Tropsch wax, 1-5% of an antioxidant and 0-5% of a filler.The Brinell viscosity of the hot melt adhesive is 6800+ / -500 / 160 DEG C, the softening point is 125+ / -10 DEG C, and the curing timeis 2.5-4s. The hot melt adhesive is suitable for automatic production of various books and magazines, and has the advantages of short curing time, excellent bonding performance, low hot melt odor, good temperature resistance, low production cost, simple preparation method, stable physical and chemical properties and suitability for roll coating and sizing modes. The adhesive has an excellent bonding effect on offset paper, coated paper, film-coated paper and the like.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a low-cost fast wireless binding hot-melt adhesive and a preparation method thereof. Background technique [0002] Books can be bound in a variety of ways: wired, wireless, stapled, and more. With the development of automated production, wireless binding has become the mainstream method of book binding. Wireless binding hot melt adhesives have developed rapidly in response to this binding method. From polyvinyl alcohol type to EVA type to PUR type, wireless binding hot melt adhesives have also developed to the third generation, of which EVA type wireless binding hot melt Glue is still the most widely used. [0003] Compared with polyvinyl alcohol, EVA type wireless binding hot melt adhesive has obvious advantages in bonding strength, curing speed and high and low temperature resistance, but compared with PUR type, except for a slight advantage in curing speed, bondin...
