[0021] (2) Add 12 parts of decabromodiphenyl ether, 1 part of ethylenethiourea, 5 parts of benzoyl peroxide, 8 parts of aluminum hydroxide, and 1 part of epoxy tetrahydrophthalic acid to the mixture 1 obtained in step (1). Dioctyl diformate and 4 parts of polyvinyl butyral were mixed at 110°C for 3 minutes, then 3 parts of magnesium stearate and 3 parts of antioxidant 1010 were added, and mixed at 95°C for 2 minutes to obtain a mixture two;

[0022] (3) Put the mixture 2 obtained in step (2) into the mill for thin pass twice, and then extrude it into the twin-screw extrud...

Embodiment 2

[0024] A preparation method of an oil-resistant cable sheath material, comprising the following steps:

[0025] (1) In parts by weight, put 67 parts of chloroprene rubber and 23 parts of polyvinyl chloride in an internal mixer and knead for 5 minutes. The temperature in the internal mixer is controlled at 140 ° C, kept for 20 minutes, and cooled to room temperature within 50 seconds. to obtain mixture one;

[0026] (2) Add 20 parts of decabromodiphenyl ether, 9 parts of ethylenethiourea, 15 parts of benzoyl peroxide, 21 parts of aluminum hydroxide, 13 parts of epoxy tetrahydro-phthalate to the mixture 1 obtained in step (1). Dioctyl diformate and 17 parts of polyvinyl butyral were kneaded at 135°C for 5 minutes, then 14 parts of zinc stearate and 16 parts of antioxidant 1010 were added, and kneaded at 110°C for 4 minutes to obtain a mixture two;

[0027] (3) Put the mixture 2 obtained in step (2) into the mill and pass through it for 5 times, and then extrude it into the twi...

Embodiment 3

[0029] A preparation method of an oil-resistant cable sheath material, comprising the following steps:

[0030] (1) In parts by weight, put 47 parts of chloroprene rubber and 11 parts of polyvinyl chloride in an internal mixer and knead for 4 minutes. The temperature in the internal mixer is controlled at 110 ° C, kept for 12 minutes, and cooled to room temperature within 35 seconds. to obtain mixture one;

[0031] (2) Add 13 parts of decabromodiphenyl ether, 2 parts of ethylene thiourea, 7 parts of benzoyl peroxide, 11 parts of aluminum hydroxide, 3 parts of epoxy tetrahydro-phthalate to the mixture 1 obtained in step (1). Dioctyl diformate and 5 parts of polyvinyl butyral were mixed at 115°C for 4 minutes, then 6 parts of polyethylene wax and 7 parts of antioxidant 1010 were added, and mixed at 100°C for 3 minutes to obtain the mixture ;

[0032] (3) Put the mixture 2 obtained in step (2) into an open mill and pass through it for 3 times, and then put it into a twin-screw ...

Abstract

The invention discloses a preparation method of an oil-resistant cable sheath material, which comprises the following steps: compounding 45-67 parts by weight of chloroprene rubber and 8-23 parts by weight of polyvinyl chloride in a Banbury mixer, keeping the temperature, and cooling to room temperature; adding 12-20 parts of decabromodiphenyl oxide, 1-9 parts of ethylene thiourea, 5-15 parts of benzoperoxide, 8-21 parts of aluminum hydroxide, 1-13 parts of dioctyl epoxytetrahydrophthalate and 4-17 parts of polyvinyl butyral, compounding for 3-5 minutes adding 3-14 parts of lubricant and 3-16 parts of antioxidant 1010, and compounding for 2-4 minutes; and carrying out thin passing in an open mill, and extruding through a double screw extruder. The cable sheath material has the advantages of higher volume resistivity, higher vertical burning grade and higher oil resistance. The method has the advantages of simple preparation technique and reasonable time and temperature control settings, and can be widely used in industrial production.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a preparation method of an oil-resistant cable sheath material. Background technique [0002] Cables are widely used, involving industries such as electric power, construction, communication, and manufacturing, and are closely related to all aspects of the national economy. [0003] CN104119681A discloses a method for preparing fire-resistant cable insulation materials. The raw materials of fire-resistant cable insulation materials are composed of the following mass components: 70%-85% of aluminum hydroxide, 10%-20% of silicone rubber, and 5-10% of additives. The additives include 96-grade SiO2 micropowder, explosion-proof fiber and composite resin; aluminum hydroxide, silicone rubber and additives are mixed evenly according to the mass ratio, and then a binding agent is added, which is composed of anhydrous glucose, borax, tropin and industrial It is composed of salt, and ...
