However, in this kind of material, the compatibility between rubber material and polyolefin resin is poor. Although the weather resistance is improved, the high temperature resistance of the base material is relatively insufficient, and the thermal stability is poor. It is easy to use in high temperature and strong corrosive environments. Oxidative denaturation
Moreover, the elastic recovery effect of this type of base tape is poor. When the tape is wound, the deformation of the base material caused by the tearing process cannot be recovered quickly, which will make it difficult for the local resistivity of the insulating tape to meet the corresponding protection requirements, which will cause serious damage. security risks

Abstract
The invention relates to the technical field of an electric material, in particular to a heat-resistant oil-resistant insulation adhesive tape with prominent stretch performance. The insulation adhesive tape is prepared from the following ingredients including polyolefin resin, reinforced elastomers, vinyl silane, a crosslinking agent, dibutyltin dilaurate, stearic acid, anti-aging agents, an organic pigment and hot meltadhesive, wherein the reinforced elastomers are a kind of elastic materials prepared by compounding inorganic filling materials and organic high-molecular polymers; the polyolefin resin is a compound prepared from polyethylene resin, polyethylene-vinyl acrylate resin and maleic anhydride grafted polypropylene according to the mass ratio of 3:5:1; the crosslinking agent selects one kind of materials from dual solvents 25, BPO, DCP and DTBP; the organic pigment selects quinacridone series pigments, benzimidazolone series pigments or thioindigo series pigments. The insulation adhesive tape has the advantages that the stretch performance is prominent; the rebounding performance is good; the deformation cannot easily occur; very excellent heat resistant, oil resistant and anti-corrosion performance is realized.
Description
technical field [0001] The invention relates to the technical field of electrical materials, in particular to a heat-resistant and oil-resistant insulating tape with outstanding tensile properties. Background technique [0002] Electrical tape refers to the tape used by electricians to insulate and prevent leakage. It is composed of a base belt and an adhesive layer. The base belt is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber and tackifying resin and other compounding agents. It has good viscosity and excellent insulation performance. It also has good characteristics of pressure resistance, flame retardancy, and weather resistance, and is suitable for wire connection, wire winding, electrical insulation protection, etc. [0003] At present, insulating tapes on the market are mainly made of soft polyvinyl chloride film as the base material and coated with rubber-type pressure-sensitive adhesive. This ki...
