Problems solved by technology
This type of product is generally only applicable to ordinary occasions. If it is used in special environments such as high-rise buildings, chemical plants, and nuclear power plants, there will be potential safety hazards. Since the cables are densely laid and criss-crossed, once a catastrophe occurs, the rescue work will be extremely difficult. difficulty
Because the heat resistance of such products is relatively low, and the second is that the PVC resin burns in case of fire after adding plasticizers. Even if some products add a certain amount of flame retardants, they will release a large amount of harmful, choking smoke

Embodiment Construction
[0007] A pvc cable material, the innovation of which is: the polymer material is composed of the following components in parts by mass: pvc resin: 100 parts by weight; plasticizer: 50-55 parts by weight; heat stabilizer: 6-8 parts by weight parts; flame retardant and smoke suppressant: 20-30 parts by weight; filler: 10-20 parts by weight. In the present invention, the plasticizer requires higher heat resistance, low volatility, and larger molecular weight. This type of plasticizer has trioctyl trimellitate (TOTM), tetraoctyl pyromellitate (TOPM), Dipentaerythritol ester, polyester, etc. The plasticizer selected in the present invention is trioctyl trimellitate and ditridecyl; the heat stabilizer is a lead salt heat stabilizer; the flame retardant and smoke suppressant is Sb2O3, zinc borate, aluminum hydroxide, hydrogen Magnesium oxide, Sb 2 O 3 is 3 parts by weight, zinc borate is 4 parts by weight, aluminum hydroxide and magnesium hydroxide are 30 parts by weight.

Abstract
The invention discloses a PVC cable material, which is characterized in that: the polymer material is composed of the following components in parts by mass: based on 100 parts by weight of pvc resin, plasticizers are required: 50-55 parts by weight; thermally stable Agent: 6-8 parts by weight; flame retardant and smoke suppressant: 20-30 parts by weight; filler: 10-20 parts by weight. The advantages of the present invention are: as can be seen from the above table, the present invention has good mechanical properties, which reflects the good heat resistance of a PVC cable material of the present invention; its oxygen index is greater than 30, indicating that the present invention is a kind of flame retardant material; due to the addition of a certain amount of flame retardant smoke suppressant and trapping agent, the present invention generates less smoke and less harmful gas when burning.
Description
[0001] technical background [0002] The invention relates to a PVC cable material, in particular to a heat-resistant and flame-retardant low-smoke and low-halogen PVC cable material. Background technique [0003] PVC cable material is a kind of plastic particle which is made of polyvinyl chloride resin as the main body, adding necessary additives such as plasticizer, thermal stability, lubricant and filler through mixing, plasticizing and pelletizing. It is mainly used for the outer leather shoes of wires and cables, and has good mechanical properties and electrical insulation properties. This type of product is generally only applicable to ordinary occasions. If it is used in special environments such as high-rise buildings, chemical plants, and nuclear power plants, there will be potential safety hazards. Since the cables are densely laid and criss-crossed, once a catastrophe occurs, the rescue work will be extremely difficult. difficulty. Because the heat resistance of s...
