Abstract

The invention provides an antibacterial hot melt adhesive and a preparation method thereof. The hot melt adhesive is prepared from the following components in parts by weight: 80-100 parts of EVA (Ethylene-Vinyl Acetate), 40-50 parts of a tackifying resin, 20-30 parts of a polyamide resin, 10-20 parts of N,N-dimethylformamide, 10-20 parts of vinyltriethylsilane, 15-20 parts of nanometer titania, 10-20 parts of zinc oxide, 5-10 parts of naphthenic oil, 5-10 parts of an antioxidant and 5-10 parts of a plasticizer. The composition and ratio of the raw materials are changed, N,N-dimethylformamide and vinyltriethylsilane are added to modify the adhesive in the preparation process, and zinc oxide and nanometer titania are added, so that the antibacterial ability of the adhesive is improved on the basis of guaranteeing the adhesiveness of the hot melt adhesive.

Description

technical field [0001] The invention belongs to the field of adhesives, and relates to an antibacterial hot-melt adhesive and a preparation method thereof. Background technique [0002] At present, hot melt adhesives can be widely used in the fields of footwear, clothing, leather goods and decorative materials due to the advantages of no solvent, no pollution, fast bonding speed, convenient compounding, simple use process, and high peel strength. They are also called green adhesives. [0003] The reason why hot melt adhesives develop rapidly is because of the stability and continuous improvement of the main material ethylene-vinyl acetate copolymer, and can be processed into film, rod, strip, and powder according to user requirements, especially different materials can be used Prepare different formulations to meet the needs of softening point, viscosity, embrittlement point and temperature. [0004] EVA hot melt adhesive is formulated from EVA resin, tackifier, plasticizer...
