Abstract

The invention discloses a halogen-free flame retardant acetate fiber cloth adhesive tape which comprises an acetate fiber cloth substrate and a pressure-sensitive adhesive layer coated on the acetate fiber cloth substrate; wherein, the pressure-sensitive adhesive comprises the components based on the weight percentage: 6.0-10.0% of thermoplastic elastomer SIS, 4.5-8.0% of natural rubber, 1.0-3.0%of styrene-butadiene rubber, 0.3-0.6% of nitrile rubber, 1.5-3.0% of abietic resin, 0.6-1.5% of phenolic resin, 8.5-16.0% of terpine resin, 2.0-7.0% of petroleum resin, 1.5-2.5% of polyisobutene, 0.4-0.6% of antioxidizer, 8.0-10.0% of halogen-free flame retardant, 0.0-1.95% of titanium pigment and 45.0-50.0% of toluene. The experiment proves that the halogen-free flame retardant acetate fiber cloth adhesive tape has good viscosity, moderate racking strength as well as good flame retardance, weather resisting property, electric property and mechanical property, and is applicable to various adhesive bonding in electronic apparatus industry.

Description

technical field [0001] The invention relates to a cellulose acetate cloth tape and a preparation method thereof, more specifically, the invention relates to a halogen-free flame-retardant cellulose acetate cloth tape and a preparation method thereof. Background technique [0002] Acetate cloth tape is an insulating tape widely used in the electronic and electrical industry, such as transformers, motors, coil capacitors and wiring harnesses, frequency conversion power supplies, etc., for fixed winding. Because the electrical and electronic industry has a particularly prominent demand for the flame retardant properties of insulating tapes, for this reason, flame retardants need to be added to acetate cloth tapes to obtain good flame retardant properties. Commonly used flame retardants are flame retardants containing halogens, including chlorine-based flame retardants, such as chlorinated paraffin, chlorinated polyethylene, tetrachlorophthalic anhydride, etc., and brominated fl...
