preparation example Construction
[0032] The present invention also provides a preparation method of the irradiation cross-linked self-adaptive permanent self-melting tape, comprising the following steps:
[0033] (1) Add the strength agent, flame retardant, colorant, tackifier and radiation cross-linking auxiliary agent into the kneader, knead at room temperature for 5 minutes, then add the silica gel, and then add the reinforcement in three times. After kneading at room temperature for 10 minutes, raise the temperature of the kneader to 130°C, and after heat treatment for 1.5 hours, the materials are completely mixed evenly to obtain a viscous base rubber;
[0034] (2) Add the coupling agent to the base glue, add the catalyst after airtight kneading for 5-10 minutes, and then take it out of the pot after airtight kneading for 5-10 minutes to prepare the mixed glue;
[0035] (3) Extrude the above-mentioned mixed rubber into a sample sheet through an extruder, and cover the sample sheet with a single layer of ...
Embodiment 1
[0039] (1) 50 parts of strength agent 30 degrees of silica gel and 5 parts of butyl rubber, 26 parts of flame retardant decabromodiphenylethane and 6.5 parts of antimony trioxide, 1.5 parts of red toner colorant, 1 part of boric acid as tackifier 1 part, 1 part of borate, 2 parts of polyisobutylene, 2 parts of radiation crosslinking auxiliary vinyl silicone oil were added to the kneader, kneaded at room temperature for 5 minutes and then added to the silica gel α, ω-terminated hydroxyl polydimethylsiloxane 25 parts of oxane, and then add 16 parts of the reinforcing agent white carbon black in three times, knead at room temperature for 10 minutes, then raise the temperature of the kneader to 130° C., and after heat treatment for 1.5 hours, the materials are completely mixed evenly to obtain a certain viscosity. Base glue;
[0040] (2) Add 4 parts of the coupling agent methyltrimethoxysilane and 1.4 parts of KH560 to the above rubber base, add 1 part of the titanate catalyst D20...
