Embodiment 1
[0029] The hot-melt pressure-sensitive adhesive for the high-temperature hook and loop tape of this embodiment is prepared from raw materials including the following components and parts by weight: 48 parts of thermoplastic elastomer, 12 parts of functionalized graphene-modified fluororesin, tackifying resin 30 parts, 4 parts of antioxidant and 5 parts of crosslinking agent.
[0030] The functionalized graphene-modified fluororesin used in this example is prepared by grafting functionalized graphene onto the fluororesin. The specific preparation method is as follows:
[0031] Step A): Mix 24 parts by weight of fluorine-containing monomer and 100 parts by weight of water evenly, while stirring, add fluorosurfactant and dispersion liquid containing functionalized graphene in turn, mix well, and then place in a vacuum environment Add an initiator, raise the temperature to 75°C for reaction, wait until the solid content of the system reaches 35%, and prepare a functionalized graph...
