Example Embodiment

[0022] A low-smoke stable cable material, which is composed of the following parts by weight:

[0023] Methyl tin thiol 3, polydimethylsiloxane 1, polyethyleneimine 4, ethyl paraben 6, polyvinyl chloride 570, yellow humic acid 17, calcium hydrogen phosphate 3, sodium iodide 0.06, iso Propanol 80, soapstone 70, sp802, epichlorohydrin 0.8, lactide 20, L arginine 0.2, mercaptobenzothiazole sodium 1, lanolin 3, castor oil polyoxyethylene ether 1, chlorinated paraffin 3 .

[0024] A method for preparing said low-smoke stable cable material includes the following steps:

[0025] (1) Add castor oil polyoxyethylene ether to 7 times water, add ethyl paraben, raise the temperature to 70°C, add calcium hydrogen phosphate, keep warm and stir for 5 minutes to obtain a calcium ester emulsion;

[0026] (2) Take 20% of the weight of the above isopropanol, add methyl tin mercaptide and 5% of the weight of the above polyvinyl chloride, and put it into an oil bath at 130°C, keep warm and stir for 10 mi...

Abstract

The invention discloses a low-smoke stable cable material. The material comprises, by weight, 3-4 parts of methyl tin mercaptide, 1-2 parts of solydimethyl siloxane, 4-7 parts of polyethyleneimine, 6-9 parts of ethylparaben, 570-600 parts of polyvinyl chloride, 17-20 parts of fulvic acid, 3-5 parts of calcium hydrophosphate, 0.06-0.1 part of sodium iodide, 80-100 parts of isopropanol, 70-100 parts of soapstone, 2-3 parts of sp80, 0.8-2 parts of epoxy chloropropane, 20-30 parts of lactide, 0.2-0.25 part of L-arginine, 1-2 parts of sodium mercaptobenzothiazole, 3-4 parts of lanolin, 1-2 parts of polyoxyethylene castor oil and 3-5 parts of chlorinated paraffin. According to the cable sheath material, the polyvinyl chloride modified by the methyl tin mercaptide is adopted so that the stability of a finished product can be well improved. The finished material is good in high and low temperature resistance, high in flame redardance and high in safety, and can effectively reduce fire risks.
