Problems solved by technology

In order to ensure the safety of the cable, the temperature of the cable must be kept within a certain range, which also limits the ability of the cable to transmit current
The temperature of the cable is closely related to the heat dissipation capacity of each layer of the cable. The material that constitutes the cable insulation and sheath is often a polymer material, and its thermal conductivity is extremely poor, which greatly limits the heat dissipation capacity of the cable, thereby limiting the load capacity of the cable. Streamlined improvement

Abstract

The invention discloses a high-thermal-conductivity insulating rubber material for a cable of an electric vehicle charging pile. The high-thermal-conductivity insulating rubber material comprises a material body, wherein the material body is prepared mainly from the following raw materials of: in parts by weight, filler, a matrix, additives and a vulcanizing agent, and 45-50 parts, by mass, of a micro nano blend system is introduced and filled into the material body. The invention also discloses a preparation method, and the preparation method mainly comprises the steps of: first treating thefiller, then preheating double rollers, performing milling again, then performing vulcanization to obtain a rubber compound, conducting hot press forming, and finally cooling to room temperature. Microstructure design during which the adopted micro nano blend system is filled into the rubber is conducted on the rubber insulating material, and therefore the overall heat-conducting performance of the insulating rubber material is greatly improved.

Description

technical field [0001] The invention relates to a rubber cable material, in particular to a high thermal conductivity insulating rubber material for an electric vehicle charging pile cable and a preparation method thereof. Background technique [0002] With the depletion of traditional fossil energy and the deterioration of the ecological environment, the development of new energy has become a strategic means for countries to deal with energy and environmental issues. Compared with traditional fuel vehicles, electric vehicles (EV) have attracted more and more attention because of their advantages such as zero pollution emissions and high energy efficiency. According to the report given by the International Energy Agency (IEA) in 2017, by the end of 2016, the global stock of electric vehicles exceeded 2 million, of which China owns about 1 / 3 of the world's total electric vehicles. However, the further promotion of electric vehicles is limited by the range and charging time. ...
