AI Technical Summary

Technical Problem

The existing double-sided adhesive is problematic of weak initial adhesion and insufficient strength during peeling, especially when meeting the needs of high-performance electronic equipment.

Method used

Hot melt double-sided adhesive is prepared using SEBS thermoplastic elastomer, polyisobutylene, modified polyurethane, modified tackifier, modified nano-silica and other materials. It is not sticky at the beginning, but it can be closely bonded to aluminum foil, nylon and other materials under high temperature and high pressure conditions.

Benefits of technology

It achieves the effect of tight bonding with aluminum foil, nylon and other materials under high temperature and high pressure conditions, and has excellent electrolyte resistance, which is suitable for polymer lithium batteries.

Abstract

The invention provides a hot-melt double-faced adhesive tape and a preparation method thereof, and the hot-melt double-faced adhesive tape comprises the following components in parts by weight: 40-60 parts of SEBS thermoplastic elastomer, 10-20 parts of polyisobutene, 5-10 parts of modified polyurethane, 3-7 parts of modified tackifier, 6-12 parts of mineral oil, 1-3 parts of modified nano silicon dioxide and 0.5-1.5 parts of antioxidant. The modified polyurethane is polyurethane modified by polydimethylsiloxane and a silane coupling agent; the modified tackifier is obtained by carrying out dehydration reaction on triethyl borate, boric acid glycerin, borate and silicon hydroxyl; the modified nano silicon dioxide is chitosan modified nano silicon dioxide; and the antioxidant is dilauryl thiodipropionate. The hot-melt double-sided adhesive tape has no viscosity initially, can be tightly bonded with materials such as aluminum foil and nylon under high-temperature and high-pressure conditions, and has excellent electrolyte resistance.
