Abstract

The invention provides a high-temperature-aging-resistant adhesive for magic tapes and a manufacturing method thereof. The manufacturing method includes the steps that double-shell hollow nano-zinc oxide is modified through N-(beta-aminoethyl)-gamma-aminopropyl methyl dimethoxy silane to obtain modified double-shell hollow nano-zinc oxide; then, adipic acid, 1, 4-cyclohexanediamine, the modified double-shell hollow nano zinc oxide and multi-amino nano silicon dioxide used as raw materials are subjected to a polymerization reaction to obtain modified low-molecular polyamide; and finally, polyethersulfone resin, the modified low-molecular polyamide, rosin resin and hydrogenated DCPD resin are mixed, melted and cooled, dibutyl phthalate is added, and heating and stirring are conducted. The adhesive for magic tapes has excellent high-temperature aging resistance and ultraviolet aging resistance, and is wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a high-temperature aging-resistant Velcro glue and a manufacturing method thereof. Background technique [0002] Velcro is a commonly used connecting accessory, one side is small and soft fibers, and the other side is hard bristles with hooks. It is used in many fields such as clothing, shoes, sofas, car cushions, curtains, tents, and various military products. There are a wide range of applications. [0003] On the basis of ordinary Velcro, hot melt adhesive can be applied on the back of the Velcro tape, and then a layer of oily release paper can be pasted to obtain the adhesive Velcro. Hot melt adhesive is a solid soluble polymer that does not require solvents and does not contain moisture. It is solid at room temperature, and when heated to a certain temperature, it becomes a fluid and viscous liquid, which can be conveniently used for back adhesive Velcro manufacturin...
