Embodiment 1

[0030] Embodiment 1: A kind of high oil resistant cable material, the material formula is as follows:

[0031]

[0032] The preparation method of above-mentioned high oil resistance cable material is as follows:

[0033] The first step: the copolymer of ethylene-vinyl acetate copolymer, metallocene polyethylene, linear low density polyethylene, ethylene-octene copolymer and polyethylene grafted maleic anhydride, and 2.5wt% of silicone and 2.5 Wt% of the halogen-free flame retardant was mixed in a high-speed mixer at a speed of 800rpm for 300 seconds, and then mixed and plasticized and granulated by a twin-screw granulator to obtain a masterbatch;

[0034] The second step: the masterbatch obtained in the first step, nitrogen and phosphorus flame retardants, silane coupling agents, crosslinking sensitizers, antioxidants, other processing aids, the remaining amount of halogen-free flame retardants and the remaining amount of Silicone, mixed in a high-speed mixer at a speed of...

Embodiment 2

[0040] Embodiment 2: A kind of high oil resistant cable material, the material formula is as follows:

[0041]

[0042] The preparation method of the above-mentioned high oil-resistant cable material is the same as in Example 1.

[0043] The performance index of embodiment 2 gained material is as follows:

[0044]

[0045]As can be seen from the above examples, the present invention increases the amount of EVA with high VA content in the material formulation and the synergistic effect between the various raw material components, so that the oil resistance of the material is significantly improved, and it has higher oil resistance and oil resistance. Flammability;.

Abstract

The invention discloses a cable material with high oil resistance and a preparing method thereof. The cable material is prepared from the following ingredients: 30-60 parts by weight of an ethylene-vinyl acetate copolymer, 10-20 parts by weight of metallocene polyethylene, 8-30 parts by weight of linear low-density polyethylene, 5-20 parts by weight of a polyethylene-octene elastomer, 5-15 parts by weight of a polyethylene grafted maleic anhydride copolymer, 120-160 parts by weight of a halogen-free flame retardant, 15-30 parts by weight of a nitrogen-phosphorus flame retardant, 0.5-2 parts by weight of a silane coupling agent, 1.5-3 parts of a crosslinking sensitizer, 1.8-3 parts of an antioxidant, 2-4 parts of silicone, and 0.5-1.2 parts of other additives. No halogen-containing materials are applied to the cable material, and thus the cable material has the characteristics of low fume, and high oil resistance, abrasion resistance and flame-retardant property without toxicity during burning.

Description

technical field [0001] The invention relates to a high oil-resistant cable material and a preparation method thereof, belonging to the field of oil-resistant cable materials. Background technique [0002] Due to the increasing use of electrification technology, cables are used in many industries. Some emerging use environments are quite special, not only requiring cables to be safe, environmentally friendly, halogen-free, low-smoke, high-temperature resistance, etc., but also require scratch resistance, high flame retardancy, and high oil resistance. Therefore, the preparation of high oil-resistant, scratch-resistant and highly flame-resistant cable materials for locomotive cables has always been a major problem to be solved in the cable material industry. Performance is very unstable. Contents of the invention [0003] The purpose of the invention is to provide a high oil-resistant cable material, which is low-smoke, halogen-free, non-toxic, easy to process, low in inpu...
