Abstract

The invention discloses an automobile environmental-friendly brake rubber pipe material. The automobile environmental-friendly brake rubber pipe material is prepared from following raw materials, by weight, 96 to 100 parts of EPDM 4770R, 1 to 2 parts of azodiisobutyronitrile, 1 to 2 parts of disodium octaborate tetrahydrate, 3 to 5 parts of dl-benzoin, 2 to 3 parts of iso-octyl methacrylate, 1 to 2 parts of 1H-benzotriazole, 10 to 15 parts of kaolin, 8 to 10 parts of nano brick slag powder, 10 to 14 parts of dibutyl phthalate, 1 to 2 parts of promoter PZ, 1 to 2 parts of anti-aging agent 4010NA, 0.7 to 1 part of sulphur, and 20 to 30 parts of a composite filling material. Production cycle of the automobile environmental-friendly brake rubber pipe material is short; energy consumption is low; and compared with existing brake rubber pipe materials, the automobile environmental-friendly brake rubber pipe material possesses relatively high hardness, and tensile strength, and excellent heat resistance, and oxidation aging resistance.

Description

[0001] technical field [0002] The invention mainly relates to the field of auto parts, in particular to an automobile environmental protection brake hose material. Background technique [0003] The mechanical steering device of the car can realize the steering of the car, but when the load on the steering shaft is large, it is difficult to turn smoothly only by the driver's physical strength as the steering energy. In order to reduce the force of the driver operating the steering wheel, people add a set of power steering assist device on the basis of the mechanical steering device, and the rubber hose in this device needs to have good resilience and strong pressure resistance. Guarantee the normal use of the device. Contents of the invention [0004] The purpose of the present invention is to provide an automobile environmental protection brake rubber hose material. [0005] The present invention is achieved through the following technical solutions: [0006] A...
