Polysilane modified insulating tape and preparation method thereof

Abstract

The invention discloses a polysilane modified insulating tape and a preparation method thereof, and relates to the technical field of communication materials. The polysilane modified insulating tape is prepared from the following components: a silane coupling agent, dimethylacetamide, polyvinyl alcohol, polyvinyl chloride, activated alumina balls, polyethyleneimine, sodium lauryl sulfate, maleic anhydride, octamethylcyclotetrasiloxane, octaphenyl-POSS, tetramethylammonium hydroxide, octaphenylcyclotetrasiloxane, 4,4'-diaminodiphenyl ether, pyromellitic dianhydride, 1-methyl-2-pyrrolidinone, calcium aluminate, butylmercaptooxo-stannane, methylene bisacrylamide, chlorinated paraffin and an acetic acid solution. The prepared polysilane modified insulating tape has thermal stability and radiation stability, surface strength of the insulating tape is effectively improved, the insulating tape has efficient waterproofness, aging resistance, permeation resistance and high-temperature resistance, the service life of the tape is prolonged with processes of substrate preparation, aging and the like, and use safety and stability of the tape are improved.

Description

Technical field: [0001] The invention relates to the field of communication materials, in particular to a polysilane modified insulating tape and a preparation method. Background technique: [0002] Insulating tape refers to the tape used by electricians to prevent leakage and provide insulation. Also known as insulating tape, tape, composed of base tape and pressure-sensitive 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 plus tackifying resin and other compounding agents, which has good viscosity and excellent insulation performance. Insulating tape has good insulation and pressure resistance, flame retardant, weather resistance, etc., and is suitable for wire connection, electrical insulation, and heat insulation protection. [0003] Direct use of plastic tape has many disadvantages: plastic tape is easy to misalign and open after a long time; when the electrical load is heavy,...

AI Technical Summary

Problems solved by technology

Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break, so it is necessary to wrap two layers of plastic tape as a protective layer at the end. The joint and the insulating self-adhesive tape of the joint do not stick to each other, and the performance is better.
