Problems solved by technology

[0002] The brake line of a car is prone to aging and breakage after being used for a period of time, resulting in brake failure and a certain potential safety hazard. The existing brake line body is composed of a hollow tube and a steel wire located in the hollow tube. Between the hollow tube and the steel wire There are lining pipes, and the hollow pipes are generally made of rubber materials. The existing rubber materials are easy to age and have a short service life; during use, due to frictional heat generation, the outer coating of the brake line is easy to soften or catch fire, and there are certain safety hazards.
[0003] The friction and supporting force between the existing inner liner and the hollow tube are not good, and the relative sliding between the inner liner and the hollow tube is easy to occur, which will cause insufficient braking force when braking, thereby affecting the braking system. Effect

Abstract

The invention relates to the technical field of brake cables, and particularly relates to an oxidation-resistant flame-retardant brake cable. The oxidation-resistant flame-retardant brake cable comprises an outer cladding layer and a steel wire, wherein a lining layer is arranged between the outer cladding layer and the steel wire; modified rubber is used as the main body of the outer cladding layer, and 1.8-3.6% of oxidation-resistant flame-retardant material is added; and the oxidation-resistant flame-retardant material comprises the following components in parts by mass: 8-12 parts of nickel-chromium-aluminium composite powder, 2-5 parts of high-temperature-resistant and oxidation-resistant graphite, 12-20 parts of modified emulsion, 1.2-2.4 parts of ceramic microbeads, 1.6-4.8 parts ofpotassium silicate and 12-24 parts of hydroxyethyl cellulose. According to the oxidation-resistant flame-retardant brake cable disclosed by the invention, an oxidation-resistant layer is arranged outside the outer cladding layer; the material structure of the oxidation-resistant layer is nanometer-scale-shaped; and the nanometer-scale-shaped structure is high in compactness and capable of effectively preventing oxygen from being diffused at a high temperature, solves the problem that an oxidizing gas makes contact with a collective material, improves the oxidation resistance, and increases the tensile strength and hardness of the outer cladding layer of the brake cable.
