Abstract

The invention discloses a hot melt adhesive for glass fiber adhesive tapes, and a preparation method thereof, wherein the hot melt adhesive comprises polyethylene terephthalate, hydrogenated rosin pentaerythritol ester, triacetin, an antioxidant and a plasticizer. The preparation method comprises: adding polyethylene terephthalate, hydrogenated rosin pentaerythritol ester, triacetin, an antioxidant and a plasticizer into a twin-screw extruder, mixing, extruding, cooling, and pelletizing to obtain the hot melt adhesive for glass fiber adhesive tapes. According to the present invention, the obtained hot melt adhesive has advantages of high softening point, high peeling strength, excellent high-temperature resistance, excellent low-temperature resistance and the like; and the preparation method has characteristics of simple preparation process and low production cost.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a hot-melt adhesive for glass fiber adhesive tapes and a preparation method thereof. Background technique [0002] Glass fiber adhesive tape is a glass fiber reinforced tape, mainly used for interlayer insulation and bundling of transformers (especially high-frequency transformers, microwave oven transformers), fixing of local components in ovens, bundling and fixing of metal strips, and heating of ceramics. Winding and fixing of devices and quartz tubes, etc. At present, most of the glass fiber adhesive tapes on the market have problems such as poor high and low temperature resistance and low peel strength, and the hot melt adhesive on the surface of the glass fiber adhesive tape will have an adverse effect on the glass fiber under high temperature conditions, resulting in tape The tensile strength itself is reduced, which eventually leads to a less than ...
