Environment-friendly hot melt adhesive

Abstract

The present invention relates to an environment-friendly hot melt adhesive, the hot melt adhesive comprises the following components in part by weight: 80-95 parts of resin, 13-17 parts of dioctyl phthalate, 18-21 parts of attapulgite, 12-16 parts of pentaerythritol ester, 3-4 parts of ferrocene, 3-7 parts of antioxidant TBM-6, 1-4 parts of mica powder, 1-3 parts of benzoin, 6-9 parts of microcrystalline wax, 1-3 parts of paraffin oil, 2-6 parts of magnesium oxide powder, 3-6 parts of angelica oil, 15-18 parts of clay, 4-5 parts of glass powder, 6-8 parts of diatomite and 10-15 parts of precipitated barium sulfate. The hot melt adhesive has the advantages of less preparation materials, low preparation cost, no any environmental pollution components, no environmental pollution after peeling when in use, and good environmental protection performance.

Description

technical field [0001] The invention relates to a hot melt adhesive, in particular to an environment-friendly hot melt adhesive. Background technique [0002] Hot melt adhesive is a solid adhesive made of thermoplastic resin or elastomer as the base material, adding tackifier, plasticizer, antioxidant, flame retardant and filler, and melting and mixing. Compared with thermosetting, solvent-based and water-based adhesives, it has many advantages. Therefore, since the 1950s, hot-melt adhesives have developed rapidly in many fields and have been used in construction, aircraft, ships and automobiles. In interior decoration and other fields, especially in printing, packaging and other industries, hot melt adhesives have been used to replace nail binding and wire binding, but the most widely used one is hot melt adhesives for bookbinding. Most of the existing hot melt adhesives have many raw materials and cost High, and some components that pollute the environment have been added...
