Abstract

The invention discloses an environment-friendly soft polyvinyl chloride hot melt pressure-sensitive adhesive tape and a manufacturing method thereof. The environment-friendly soft polyvinyl chloride hot melt pressure-sensitive adhesive tape consists of an inner polyvinyl chloride calendering thin film and an outer hot melt pressure-sensitive adhesive, wherein the outer hot melt pressure-sensitive adhesive is applied to the surface of the polyvinyl chloride calendering thin film. The manufacturing method comprises the following steps of mixing ethylene-type polyvinyl chloride resin powder, trioctyl trimellitate, powdered barium and zinc heat stabilizer, high-temperature color cake and nanometer calcium carbonate to form a polyvinyl chloride thin film; adding butyl rubber slices, hydrogenated styrene-butadiene block polymer, naphthenic oil, an antioxidant and an anti-aging agent into a reaction kettle, smelting, adding low-molecular weight polyisobutene and hydrogenated petroleum resin, and finally adding polyethylene wax and pigment; smelting, so as to obtain the hot melt pressure-sensitive adhesive; covering the prepared hot melt pressure-sensitive adhesive to the surface of the polyvinyl chloride thin film, so as to obtain the environment-friendly soft polyvinyl chloride hot melt pressure-sensitive adhesive tape. The preparation method has the advantages that the smelting energy consumption is decreased, the cost is effectively reduced, the obtaining of materials is easy, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an environment-friendly soft polyvinyl chloride hot-melt pressure-sensitive adhesive tape and a production method thereof. Background technique [0002] At present, no matter the polyvinyl chloride electrical tape used in the industrial field or the civilian field is a solvent-based rubber pressure-sensitive adhesive and an ordinary soft polyvinyl chloride (SPVC) film, the tape contains organic solvents, which pollutes the environment, and Ordinary polyvinyl chloride will also release some harmful substances, which will cause harm to the environment and human body. The industry and manufacturers are also actively looking for effective solutions, but with little success. Because, the environmentally friendly hot-melt pressure-sensitive adhesive recognized by the industry at present, after being combined with ordinary PVC coating, it is easy for the plasticizer...
