Problems solved by technology

[0004] Patent CN104650441A discloses a ceramizable flame-retardant polymer composite material, which is made of polyolefin resin or thermoplastic polyurethane elastomer and ceramic filler in a ratio of almost 1:1, and the ceramic filler also has low softening Point glass powder, because the fusion of low softening point glass powder and organic polymer is poor, although it can increase the refractory temperature, but the fracture strength is significantly reduced, which affects its service life

Embodiment 1

[0013] A porcelain-forming low-smoke halogen-free polyolefin cable material, based on parts by weight, composed of the following components: 82 parts of polyolefin resin, 10.5 parts of aryl epoxy resin, 4 parts of silane coupling agent, diatom 25 parts of soil, 8.5 parts of titanium dioxide, 0.8 parts of N-aminoethylpiperazine, 0.8 parts of hexamethylene diamine ketimine, 10 parts of alumina, 5.5 parts of epoxy-terminated liquid nitrile rubber, 7.5 parts of nano magnesium oxide whiskers , 3.5 parts of paraffin oil. The specific preparation process is as follows: first fully mix the silane coupling agent with diatomaceous earth, titanium dioxide and alumina, and then send it to the internal mixer in proportion with other raw materials, mix at 135°C for 28 minutes, and then extrude it by the granulator After granulating, the product is obtained. The cable sheath prepared by using the cable material can realize porcelain formation when exposed to an open flame at a high temperatu...

Abstract

The invention discloses a porcelain-formable low-smoke halogen-free polyolefin cable material and a preparation method thereof. The porcelain-formable low-smoke halogen-free polyolefin cable materialis prepared from, by weight, 80-85 parts of polyolefin resin, 10-12 parts of aryl epoxy resin, 3-5 parts of silane coupling agents, 20-40 parts of diatomite, 8-10 parts of titanium dioxide, 0.5-2 parts of N-aminoethylpiperazine, 0.5-2 parts of hexamethylenediamine ketimine, 8-12 parts of aluminium oxide, 5-8 parts of epoxy-terminated liquid nitrile rubber, 2-10 parts of nanometer magnesium oxide whiskers and 3-5 parts of paraffin oil. The porcelain-formable low-smoke halogen-free polyolefin cable material can form porcelain with flame at 600 DEG C or above and form a protection layer, and hasa high extension rate and good mechanical performance.

Description

Technical field [0001] The invention belongs to the technical field of organic materials, and specifically relates to a ceramic-forming low-smoke halogen-free polyolefin cable material. Background technique [0002] With the rapid development of my country's electronics industry, wires and cables have been widely used in many fields. In ordinary environments, general cables can be used normally, but in some extreme environments, especially in some unexpected situations, this This kind of ordinary cable has great disadvantages. The cable wire covered with the ceramic-forming cable material has the performance of high temperature resistance. After being burned in the fire, it can quickly form a high temperature resistant ceramic, which blocks the flame from the inner conductor of the cable and ensures the cable's operation under extreme conditions. . [0003] CN104497404A discloses a porcelainizable polyolefin composite material, which is prepared by mixing polyolefin resin and porc...
