Problems solved by technology

[0005] However, unilaterally increasing the hardness of ethylene-propylene rubber and reducing costs by filling a large amount of low-cost filler materials will inevitably affect factors such as insulation strength and electrical properties. Even if the product can be successfully handed over to the customer, the cable cannot be guaranteed. Can have a long service life

specific Embodiment 1

[0025] A low-cost high-performance insulating rubber material disclosed by the present invention is selected from 60 parts of EPDM rubber, 40 parts of POE, 2 parts of dicumyl peroxide, 1 part of TAIC, 15 parts of plasticizer, and 2 parts of anti-aging agent. 150 parts, 150 parts of talcum powder, 50 parts of pottery clay, 4 parts of white carbon black.

[0026] Put the above materials (except dicumyl peroxide and TAIC) into the internal mixer and knead for 2~3 minutes, lift the top bolt to sweep the material, repeat twice, and then continue kneading until the temperature shows 120°C. The rubber is discharged to the open mill and mixed by turning over the bag, and the rubber is filtered by the rubber filter, and then the strips are not opened, and then put into the internal mixer after cooling, adding dicumyl peroxide and TAIC, and the mixing time is 1~2min. The strips are cut out on the three-roller laminator, and the finished product is put into the continuous sulfur workshop...

Abstract

The invention discloses a low-cost high-performance insulating rubber material which is prepared from the following raw materials in parts by weight: 60-80 parts of ethylene propylene diene monomer, 20-40 parts of elastomer, 2-5 parts of crosslinking agent, 1-2 parts of auxiliary crosslinking agent, 10-15 parts of plasticizer, 1-5 parts of anti-aging agent, 120-150 parts of talcum powder, 50-80 parts of argil and 4-6 parts of silica white. The low-cost high-performance insulating rubber material can be used for preparing various cable insulation core insulation layers, and is especially suitable for multi-core cables to prevent the cores from being flattening by the adjacent cores in the cable formation and jacket extrusion process.

Description

technical field [0001] The invention relates to an insulating material, in particular to a low-cost and high-performance insulating rubber material with high hardness, high strength and good insulating performance. Background technique [0002] Insulation materials are an essential part of the wire and cable industry, and the quality of insulation performance is a key factor to measure the quality of cables. With the price drop in recent years, ethylene propylene rubber has become the best choice for insulating materials, and it has also become a research hotspot in the cable industry. [0003] The ethylene-propylene rubber obtained in the prior art needs to ensure sufficient strength, and its hardness is generally low. Therefore, during the process of cabling and extruding the outer sheath of the insulated core, the insulating layer is subjected to the extrusion force from the adjacent core. It is very easy to be flattened, resulting in unqualified local insulation thickne...
