AI Technical Summary

Problems solved by technology

The volatilization of these organic solvents into the air during the production process not only causes a waste of resources, but also causes serious environmental pollution, and a very small amount of organic solvents will inevitably remain in the adhesive layer of the adhesive tape product. It will be released slowly during use, which will pollute the use environment

Abstract

The invention provides a pressure sensitive adhesive for producing SPVC (soft polyvinyl chloride) electrical adhesive tapes and a processing method of the pressure sensitive adhesive. The pressure-sensitive adhesive is prepared from components as follows: 30-40 parts by weight of a tackifying copolymer emulsion, 65-75 parts by weight of rubber latex and 5-10 parts by weight of an aid; the tackifying copolymer emulsion comprises components as follows: 85 parts by weight of isooctyl acrylate, 12 parts by weight of butyl acrylate, 3 parts by weight of acrylic acid, 10 parts by weight of vinyl acetate, 1.5 parts by weight of hydroxyethyl methylacrylate, 0.15 parts by weight of benzoyl peroxide and 100 parts by weight of toluene. The tackifying copolymer emulsion in the pressure sensitive adhesive improves holding power of the product, the use amount of organic solvent toluene is reduced in the overall formula, and energy saving, emission reduction and environmental protection are facilitated.

Description

technical field [0001] The invention belongs to the technical field of light industry, and in particular relates to a pressure-sensitive adhesive and a processing method thereof. Background technique [0002] Electrical pressure-sensitive adhesive tapes based on soft polyvinyl chloride (SPVC) film have excellent mechanical properties (especially flexibility and stretchability), flame retardancy, electrical insulation, heat deformation resistance and processing applications Therefore, it is widely used in the insulation coating and bundling of various electrical components and wires in the fields of automobiles, machinery manufacturing, instrumentation and household appliances. Soft polyvinyl chloride (SPVC) electrical adhesive tape is a larger category of pressure-sensitive tape products. [0003] At present, the soft polyvinyl chloride tape products in industry are all made by coating a soft polyvinyl chloride film substrate with a solvent-based rubber pressure-sensitive a...
