Problems solved by technology

Polyester electrical tape, also known as Mylar tape, is made of polyester film and solvent-based pressure-sensitive adhesive. It has high tensile strength and high temperature resistance. It is used in the manufacture of various transformers. Some existing tapes have flame retardant effects. Poor, it is easy to produce harmful substances under high temperature or burning. Some existing substrates will greatly increase the aging speed when exposed to strong light, and the service life is low. Moreover, leather absorbs heat relatively strongly at high temperatures, and the temperature rises quickly. , aging faster

Embodiment Construction

[0022] The present invention is further illustrated below by way of examples.

[0023] A PVC electrical tape base material for sun protection, comprising the following components in parts by weight: 90-110 parts of PVC resin, 60-80 parts of filler, 20-40 parts of plasticizer, 4-5 parts of stabilizer, and 1 part of lubricant ~2 parts, 3~4 parts of flame retardant and 4~5 parts of sunscreen agent; The flame retardant comprises the following components by weight: 3~4 parts of perchlorocyclopentane, 1~2 parts of chlorendic acid, and 3 to 4 parts of gold potassium chloride; the sunscreen comprises the following components by weight: 1 to 2 parts of oblique zeolite, 3 to 4 parts of lauryl acrylate, and 1 to 2 parts of sodium polydithiodipropane sulfonate.

[0024] The plasticizer is a mixture of DIOP and DOS in a ratio of 1:2.

[0025] The filler is a mixture of calcium carbonate and mica powder in a ratio of 1:1. Helps increase the strength of the leather.

[0026] A kind of cal...

Abstract

The invention discloses a sun-proof PVC electrical tape base material and a calendering method thereof, and relates to the technical field of adhesive tapes. The base material is characterized by comprising the following components in parts by weight: 90 to 110 parts of PVC resin, 60 to 80 parts of filler, 20 to 40 parts of plasticizer, 4 to 5 parts of stabilizer, 1 to 2 parts of lubricant, 3 to 4 parts of flame retardant, and 4 to 5 parts of sun-screening agent. The flame retardant comprises the following components in parts by weight: 1 to 2 parts of clinoptilolite, 3 to 4 parts of lauryl acrylate, and 1 to 2 parts of sodium 3,3'-dithiodipropane sulfonate. The base material has the advantages of good flame retardant effect, good environment-friendly property, and good sun-screening effect, and can reduce the aging speed, the service life is prolonged, and the base material is uniform.

Description

[0001] Technical field: [0002] The invention relates to the technical field of adhesive tapes, in particular to a sun-proof PVC electrical adhesive tape base material and a calendering molding method thereof. [0003] Background technique: [0004] Electrical tape is made of film as the base material and rubber-coated pressure-sensitive adhesive. It has good insulation, flame resistance, voltage resistance, and cold resistance. It is suitable for automotive wiring, wire winding, and insulation protection. Polyester electrical tape, also known as Mylar tape, is made of polyester film and solvent-based pressure-sensitive adhesive. It has high tensile strength and high temperature resistance. It is used in the manufacture of various transformers. Some existing tapes have flame retardant effects. Poor, it is easy to produce harmful substances under high temperature or burning. Some existing substrates will greatly increase the aging speed when exposed to strong light, and the ser...
