Abstract

The invention discloses an antibacterial EVA (Ethylene-Vinyl Acetate) edge-sealing hot melt adhesive material, which is prepared from the following components in percentage by mass: 20 to 55 percent of EVA, 10 to 55 percent of tackifying resin, 2 to 10 percent of styrene-isoprene-styrene block copolymer (SIS), 0.1 to 5 percent of antibacterial agent, 5 to 60 percent of calcium carbonate, 1 to 10 percent of viscosity modifier, 0.1 to 0.2 percent of antioxidant and 3 to 18 percent of plasticizer, according to the invention, an inorganic antibacterial agent silver-loaded zeolite antibacterial agent is adopted as an antibacterial agent and is blended in an EVA hot melt adhesive material, so that on one hand, the hot melt adhesive can meet the use temperature requirements of viscosity, softening point, bonding force and the like, on the other hand, the EVA hot melt adhesive is endowed with relatively good antibacterial and mildew-proof functions, and the EVA hot melt adhesive is suitable for home edge sealing application of various base materials and plates; the EVA hot melt adhesive does not mildew when being used in various humid environments, prolongs the service life of the furniture, and expands the functionality of the EVA hot melt adhesive.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an antibacterial EVA edge-sealing hot-melt adhesive material and a preparation method thereof. Background technique [0002] EVA hot melt adhesive is a solvent-free, moisture-free, non-polluting 100% solid thermoplastic resin. It is solid at room temperature, and can soften and flow after heating and melting to a certain temperature. It can be used for adhesive bonding materials. The preparation method is simple, the bonding speed is fast, the peeling strength is high, and it can be processed into various shapes according to the needs, which can meet the needs of different equipment. It is widely used in the fields of furniture, clothing, shoes and leather goods. It is a kind of green environmental protection of hot melt adhesives. [0003] Conventional EVA hot melt adhesives are usually prepared by blending ethylene-vinyl acetate, tackifiers, antioxidants, etc., which can mee...
