Problems solved by technology

Although the performance of the existing electrical tape has been greatly improved, there are still poor flame retardant, insulating and antistatic effects of the base material, which affects the overall effect of the electrical tape
Chinese patent CN1238456C, "polyvinyl chloride electrostatic film tape", although this patent proposes a self-adhesive PVC electrostatic film tape, but the flame retardant effect of its substrate is relatively poor; Chinese patent CN100532485C, "a high temperature resistant Insulating Tape", the patent uses silicone rubber and glass fiber composite base surface, so that it has the characteristics of high temperature resistance, its heat resistance temperature is high in a short time, but the normal heat resistance temperature is still low

Abstract

The invention relates to a flame-retardant PVC (polyvinyl chloride) electrical adhesive tape substrate which comprises the following raw materials in parts by mass: 80-100 parts of PVC resin powder, 20-30 parts of rubber powder, 40-90 parts of inorganic flame retardant, 30-45 parts of plasticizer, 1-4 parts of heat stabilizer and 0.1-0.5 part of lubricant, wherein the inorganic flame retardant is one or more of antimony trioxide, magnesium hydroxide and aluminum hydroxide; the plasticizer is phthalate, epoxide, aliphatic dibasic acid ester or citrate; the stabilizer is composite stabilizer; and the lubricant is one or more of calcium stearate, stearic acid or oxidized polyethylene wax. The electrical adhesive tape substrate provided by the invention has excellent high temperature resistance and favorable insulating property and flame retardancy, the heat-resistance temperature can be up to 320 DEG C, and the maximum LOI value can be up to 79; and compared with the common PVC electrical adhesive tape substrate, the heat-resistance temperature can be increased by 120 DEG C, and the LOI value can be increased by 49 at most.

Description

Technical field [0001] The invention belongs to the field of electrical tapes, and specifically relates to a flame-retardant PVC electrical tape substrate. Background technique [0002] At present, electrical tape is mainly made of soft polyvinyl chloride (PVC) film as the base material and coated with rubber-type pressure-sensitive adhesive. It has good insulation and is mainly suitable for the insulation of various electronic parts, automotive wiring, Wire winding, insulation protection, etc. Although the performance of the existing electrical tape has been greatly improved, the flame retardant, insulating and antistatic effects of the base material are still poor, which affects the overall effect of the electrical tape. Chinese patent CN1238456C, "Polyvinyl chloride electrostatic film tape", although this patent proposes a self-adhesive PVC electrostatic film tape, but its substrate has poor flame retardant effect; Chinese patent CN100532485C, "a kind of high temperature res...
