Formula for low-smoke environment-friendly oil-resistant insulating cable

Abstract

The invention discloses a formula for a low-smoke environment-friendly oil-resistant insulating cable. The low-smoke environment-friendly oil-resistant insulating cable is prepared from, by weight, 40-50 parts of SG-1 type resin, 30-38 parts of plasticizer, 35-40 parts of an antioxidant, 20-30 parts of hydrous zinc borate, 40-60 parts of magnesium hydrate, 9-20 parts of TCP, 1.9-2.6 parts of an antioxidant, 33-39 parts of a stabilizer, 40-46 parts of DOP, 30-60 parts of chlorinated paraffin, 38-40 parts of dioctyl phthalate, 20.6-30.9 parts of dioctyl terephthalate, 28-32 parts of epoxidized soybean oil, 10.8-26 parts of vinyl acetate, 20-36 parts of light calcium carbonate and 30-50 parts of heavy calcium carbonate. The formula is reasonable and scientific, the cable is good in radiation resistance, good in waterproofness and excellent in mechanical property, mechanical physical performance of the produced finished product cable is higher than that of a common rubber cable, and the cable has flame resistance and abrasion resistance and is high in use safety and long in service life.

Description

technical field [0001] The invention relates to a low-smoke, environment-friendly and oil-resistant insulating cable formula. Background technique [0002] Cable sheath is widely used in the cable manufacturing process. Its withstand voltage and insulation resistance are relatively high, but its dielectric constant and dielectric loss are relatively large. Generally, it is mainly used as insulation for low-voltage (≤1KV) and medium-high voltage (6~10KV) cables. Floor. The heat resistance and oil resistance of the cable sheath prepared by traditional methods are difficult to have at the same time, especially when the cable sheath has heat resistance, the content of organic matter contained in the material is high, it is easy to expand and deform when exposed to hot oil, and it is easy to soften after long-term soaking. Rotten, oil resistance is difficult to guarantee. At the same time, the traditional method for preparing cable sheaths is complicated and not environmentally...

Problems solved by technology

The heat resistance and oil resistance of the cable sheath prepared by traditional methods are difficult to have at the same time, especially when the cable sheath has heat resistance, the content of organic matter contained in the material is high, it is easy to expand and deform when exposed to hot oil, and it is easy to soften after long-term soaking. Rotten, oil resistance is difficult to guarantee

At the same time, the traditional cable skin preparation method is complex and not environmentally friendly, and the prepared cable skin is prone to odor when exposed to heat and oil.
