Composite cable for igniter motor and preparation method of composite cable

Abstract

The invention relates to a cable rubber, and particularly discloses a composite cable for an igniter motor and a preparation method of the composite cable. The preparation method reduces the phenomenon of adhesion on a roller in the mixing process of the preparation of a seal sheath, the actual operation time is shortened, the risk of ageing of the raw material is reduced on the basis of improvingthe preparation efficiency, and the obtained seal sheath material of the composite cable has the advantages of high temperature resistance and high strength. The composite cable for the igniter motoris prepared by sequentially assembling an inner conductor, an insulating layer, a waterproof layer and the sheath from inside out, and the cable has the advantages of high temperature resistance andhigh strength. The preparation method is strong in operability, has obvious effects, and has a very high promotion and application value.

Description

technical field [0001] The invention relates to cables, in particular to a composite cable for an ignition engine and a preparation method thereof. Background technique [0002] With the development of science and technology, the improvement of engine performance, the increase of local temperature of the fuselage, and the enhancement of vibration intensity, the requirements for high temperature resistance of cable sealing sheaths are getting higher and higher. [0003] The existing cable sealing sheath not only fails to meet the increasingly stringent electrical safety requirements of today, but also has poor bonding strength with the metal casing, is prone to aging, blistering and delamination, loss of elasticity, and even detachment from the metal casing , In serious cases, it will cause a fire accident, which cannot meet the requirements of long-term safe and effective continuous work. The short service life of the ignition engine cable sealing sheath, poor electrical pe...

Problems solved by technology

[0005] However, due to the addition of a large amount of additives and fillers during the preparation process, the sticky roll phenomenon occurs during the preparation process, and the sticky roll further leads to uneven mixing and uneven performance of rubber products. In addition, the preparation process requires multiple Cleaning the sticky rollers will lead to a long preparation time, and the extension of the mixing time will further cause the aging of the rubber raw materials, increasing the risk of the strength and performance of the prepared rubber products decreasing

However, if the addition of fillers is greatly reduced, although the sticking phenomenon will be reduced, the performance of the rubber will be reduced, which does not meet the requirements of rubber for ignition engines, such as high temperature resistance and high strength.
