Problems solved by technology

Commonly used in rubber insulation is EPDM as the base material, using the vulcanizing agent DCP and the vulcanization accelerator TAC. The disadvantages of the compound rubber are: the elongation at break is low, and the process range is narrow during the vulcanization process. If extruded When the temperature is too high, it is easy to break and the elongation rate is unqualified

Embodiment 1

[0021] Embodiment 1. A kind of manufacture method of aging-resistant insulating rubber cable material, comprises the following steps:

[0022] Step 1. First mix 8-14 parts of chlorinated polyethylene and 19-21 parts of ethylene-octene copolymer elastomer in an internal mixer by weight percentage;

[0023] Step 2. Add 5 to 8 parts of 800# paraffin-based rubber oil, 0.8 to 1 part of activated magnesium oxide, 1 to 2 parts of activated zinc oxide, 0.3 to 0.6 parts of environmental stabilizer, and microcrystalline wax to the internal mixer. 1~2 parts, 0.7~0.9 parts of titanium dioxide, 0.5~0.6 parts of 4,4′bis(α,αdimethylbenzyl)diphenylamine, mixing for 2~3 minutes;

[0024] Step 3. Then, add 25 to 31 parts of modified calcined clay and 5 to 7 parts of superfine talcum powder into the internal mixer and mix for 3 to 5 minutes, and the internal mixer discharges the mixed rubber material;

[0025] Step 4. Pass the mixed rubber material on the mill for 1 to 2 times, put the rubber 2...

Embodiment 2

[0035] Example 2. A manufacturing method of aging-resistant insulating rubber cable material. The formula of each component of the material is: chlorinated polyethylene (CPE) 12 kg, ethylene-octene copolymer elastomer (POE) 19 kg, 800# paraffin 7 kg of base rubber oil, 0.8 kg of activated magnesium oxide, 1.5 kg of zinc oxide, 7 kg of superfine talcum powder, 0.5 kg of environmental stabilizer, 1.5 kg of microcrystalline wax, 0.8 kg of titanium dioxide, 30 kg of modified calcined clay, 4, 0.6 kg of 4' bis(α,α dimethylbenzyl) diphenylamine, 1.5 kg of dicumyl peroxide, and 1.2 kg of triallyl cyanurate.

Abstract

The present invention discloses a method for producing an anti-aging rubber insulated cable material, and the method comprises the following steps: first chlorinated polyethylene and an ethylene-octene copolymer elastomer are mixed in a mixer in weight ratio; then 800 # paraffinic base rubber oil, active magnesium oxide, active zinc oxide, an environmental protection stabilizer, microcrystalline wax, titanium dioxide and 4,4 'bis (alpha, alpha-dimethylbenzyl) diphenylamine are added into the mixer for blending; then modified calcined clay and superfine talc powder are added into the mixer for blending, and a blended rubber material is discharged from the mixer; after filtered rubber is stored for 24 hours, the rubber material is again put into the mixer for blending, vulcanizing agent dicumyl peroxide and triallyl cyanurate are added for blending for about 2-3min, and the material is discharged. Mooney viscosity of the anti-aging rubber insulated cable material is low, when a same filling material is added, a plasticizer needed for achievement of same Mooney viscosity is less, and the heat resistance and the weather resistance of the blended rubber material are improved.

Description

technical field [0001] The invention relates to a manufacturing method of a cable material, in particular to a manufacturing method of an aging-resistant insulating rubber cable material. Background technique [0002] The cable sheath is the outermost layer of the cable. The cable sheath material not only needs to have excellent physical properties, such as tensile strength, elongation at break, etc., but also needs to have good flame retardancy. Commonly used in rubber insulation is EPDM as the base material, using the vulcanizing agent DCP and the vulcanization accelerator TAC. The disadvantages of the compound rubber are: the elongation at break is low, and the process range is narrow during the vulcanization process. If extruded When the temperature is too high, it is easy to fail the elongation at break. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of aging-resistant insulating rubber cable material. The ...
