Embodiment 1

[0018] In the embodiment of the present invention, an epoxy resin cable material is composed of the following raw materials in parts by weight: 68 parts of epoxy resin, 33 parts of Wulingzhi, 10 parts of bentonite, 5 parts of titanate coupling agent, polypropylene 43 parts of resin, 10 parts of talcum powder, 3 parts of sodium bifluoride.

[0019] Add 15 times the mass of Wulingzhi to Wulingzhi with ethanol with a mass concentration of 90%, heat and reflux for extraction, let cool to room temperature, filter, collect the ethanol extract, and concentrate to 11% of the original volume; spray-dried to obtain Wulingzhi extract. Put the epoxy resin into 90% ethanol which is 13 times its mass, raise the temperature to 66°C at a speed of 100r / min, then add talcum powder and stir for 8min, then cool down to 45°C, then add sodium bifluoride and Bentonite, after stirring for 1 h, mixture A was prepared. Add polypropylene resin and titanate coupling agent to mixture A, raise the temper...

Embodiment 2

[0021] In the embodiment of the present invention, an epoxy resin cable material is composed of the following raw materials in parts by weight: 75 parts of epoxy resin, 39 parts of Wulingzhi, 16 parts of bentonite, 10 parts of titanate coupling agent, polypropylene 48 parts of resin, 16 parts of talcum powder, 8 parts of sodium bifluoride.

[0022] Add 95% ethanol with a mass concentration of 16 times the mass of Wulingzhi to Wulingzhi, heat and reflux for extraction, let cool to room temperature, filter, collect the ethanol extract, and concentrate to 13% of the original volume; spray-dried to obtain Wulingzhi extract. Put the epoxy resin into ethanol with a mass concentration of 95% that is 15 times its mass, raise the temperature to 68°C at a speed of 150r / min, then add talcum powder and stir for 10 minutes, then cool down to 48°C, then add sodium bifluoride and Bentonite, after stirring for 1.5h, mixture A was prepared. Add polypropylene resin and titanate coupling agent...

Embodiment 3

[0024] In the embodiment of the present invention, an epoxy resin cable material is composed of the following raw materials in parts by weight: 70 parts of epoxy resin, 35 parts of Wulingzhi, 12 parts of bentonite, 7 parts of titanate coupling agent, polypropylene 45 parts of resin, 12 parts of talcum powder, 5 parts of sodium bifluoride.

Abstract

The invention discloses an epoxy resin cable material and a preparing method and application thereof. The epoxy resin cable material is prepared from, by weight, 68-75 parts of epoxy resin, 33-39 parts of trogopterus dung, 10-16 parts of bentonite, 5-10 parts of titanate coupling agents, 43-48 parts of polypropylene resin, 10-16 parts of talcum powder and 3-8 parts of sodium hydrogenfluoride. The preparing method includes the steps that the trogopterus dung is treated to obtain trogopterus dung extrct; the epoxy resin is put in ethyl alcohol to be treated, then the talcum powder is added, temperature is lowered, sodium hydrogenfluoride and the bentonite are added, the polypropylene resin and the titanate coupling agents are added, the trogopterus dung extrct is added after treatment is carried out, and the epoxy resin cable material is obtained after mixing and pelleting. The preparing method is simple and convenient to operate, the composition raw material formula is reasonable, and the prepared cable material has the advantages of being high in mechanical property, resistant to cold, high temperature and abrasion, high in flame retardant property and soft, has an electric insulation function and is low in fume and nontoxic when being combusted.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an epoxy resin cable material and its preparation method and application. Background technique [0002] Cable (electriccable; powercable): usually consists of several or several groups of wires. With the rapid development of the economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which is a risk factor in a fire. It hinders people's safe evacuation and fire fighting work during a fire, causing serious loss of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wir...
