[0134] Preparation of oil-resistant TPE cable material

[0135] The preparation method of oil-resistant TPE halogen-free flame-retardant cable material described in the present invention comprises:

[0136] (a) mix SEBS and plasticizer, obtain blend 1;

[0137] (b) mix polyphenylene ether, TPEE, polyolefin resin, composite halogen-free flame retardant, flame retardant aid, processing aid, composite antioxidant with the blend 1 obtained in step (a) to obtain a blend object 2; and

[0138] (c) granulating Blend 2;

[0139] Thus, the oil-resistant TPE cable material is obtained.

[0140] The amount of each component described in the method is as described above. Preferably, in step (a), the SEBS and the plasticizer are fully blended and left to stand for a period of time, such as 15 to 28 hours, such as about 24 hours. Then mix with other ingredients.

[0141] In a preferred embodiment, the polyphenylene ether, TPEE, and polyolefin resin are fully mixed with the blend 1 f...

Embodiment 1－6

[0151] The oil-resistant TPE cable materials of Examples 1-6 were prepared according to the composition in the table below.

[0152]

[0153]

[0154] Among them, the elastomer resin SEBS used in Examples 1-3 is TSRC 6151; the elastomer resin used in Examples 4-6 is Kraton G-1651.

[0155] Among them, the polyphenylene ether resin PPO used in Examples 1 to 6 is the PPO resin produced by Bluestar Chemical Industry.

[0156] Wherein, the elastomer resin TPEE used in Examples 1-6 is Taiwan Changchun CCP series TPEE resin with a hardness of 40D.

[0157] Wherein, the polyolefin resin used in Examples 1-3 is polypropylene resin, and the polyolefin resin in Examples 4-6 is LLDPE resin.

[0158] Among them, the plasticizer used in Examples 1-6 is Hanglian No. 36 white oil, and this type of white oil is paraffin-based white oil.

[0159] Wherein the flame retardant used in embodiment 1,3,5 is that RDP and mica powder are compounded according to 15:10 to make, and wherein the f...

Abstract

The invention relates to an oil-resistant TPE (thermoplastic elastomer) halogen-free flame-retardant cable material and a preparation method thereof. The cable material comprises the following components in parts by weight: 20-50 parts of SEBS (styrene-ethylene-butadiene-styrene), 20-40 parts of PPO (polypropylene oxide), 5-20 parts of TPEE (thermoplastic polyether ester elastomer), 10-25 parts of polyolefin resin, 20-50 parts of plasticizer, 20-60 parts of composite halogen-free flame retardant, 1-8 parts of flame-retardant assistant, 1-5 parts of processing assistant and 1-5 parts of antioxidant. The cable material can be used as an oil-resistant cable coating material, and overcomes the defect of poor oil resistance in the SEBS / PP (polypropylene) blend TPE elastomer system and the detects of poor oil resistance and poor crack resistance in the PPO system. The obtained product has very excellent comprehensive properties in the aspects of flexibility, thermal shock resistance, strength, elongation percentage and flame retardancy.

Description

technical field [0001] The invention relates to an oil-resistant TPE halogen-free flame-retardant cable material that can be used as an oil-resistant cable outer coating and a preparation method thereof. Background technique [0002] As people's requirements for cable softness and cable feel are increasing day by day, elastic system materials have gradually entered the cable material industry, and have huge development potential and market prospects. At the same time, in the process of dealing with the non-halogenation of cable materials to replace PVC materials, compared with traditional low-smoke non-halogen polyolefin materials with high hardness, elastomer materials have huge advantages due to their own characteristics. [0003] The industrialization of thermoplastic elastomers in cable materials has been a hot topic in the past ten years. At present, its application is limited due to its own defects, such as poor high temperature resistance, difficult flame resistance, ...
