Cooling adhesive tape

Abstract

The invention discloses a cooling adhesive tape, which consists of a PET (polyethylene terephthalate) substrate layer and a cooling adhesive layer applied on one surface of the PET substrate layer, and the cooling adhesive layer is prepared from the following components in parts by weight: 0.5 to 1.3 parts of heat-conducting silicone oil, 80 to 100 parts of methyl methacrylate, 2 to 10 parts of methacrylic acid, 15 to 30 parts of polymethyl methacrylate, 0.05 to 0.5 part of diethyl aniline, 0.07 to 0.9 part of methyl ethyl ketone peroxide, 0.03 to 0.09 part of cobalt naphthenate, 2 to 15 partsof crylic acid, 10 to 40 parts of ethyl acetate, 3 to 6 parts of titanium dioxide, 2 to 15 parts of pigment, 0.3 to 3 parts of halogen-free flame-retardant curing agent and 2 to 11 parts of graphene.The toughness of the adhesive layer is high, the viscosity is high, the insulativity is good, high temperature can be resisted, cooling is fast, the risk of fire and explosion of electric appliancesor batteries is reduced, and the invention is applicable to adhesive tapes for lithium batteries.

Problems solved by technology

[0004] Lithium battery tape needs to have high-quality and stable working properties due to the application environment, such as electrolyte resistance, moderate peeling force and unwinding force, high temperature resistance, aging resistance, and excellent tensile strength. Lithium batteries in current technology exist due to limitations. There is a risk of explosion, and the aging damage of lithium battery tape due to lack of high temperature resistance is also one of the risk factors
