Abstract

The invention discloses a sealing part for an automobile LED instrument panel. The sealing part is prepared from raw materials in parts by weight as follows: 50-60 parts of a main material, 0.5-1.2 parts of disproportionated rosin, 1-2 parts of polyphenylene sulfide, 0.4-1 part of polybenzoate, 55-65 parts of filler, 0.2-1 part of di-tert-butyl peroxide, 1-2 parts of 2,4-dichlorobenzoyl peroxide, 0.4-1 part of maleic anhydride, 0.2-0.8 parts of 3-(2-aminoethylamino)propyl-dimethoxymethylsilane, 0.4-1 part of butyl titanate, 1-3 parts of magnesium stearate, 1-2 parts of coal tar and 1-3 parts of an anti-aging agent. The sealing part for the automobile LED instrument panel has high density, good toughness, extremely high waterproof performance and excellent tearing resistance.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a seal for an automobile LED instrument panel. Background technique [0002] The instruments on the LED dashboard of different cars are not the same, but the conventional instruments of a general car include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. In modern cars, automotive LED meters also need to be equipped with voltage regulators, which are specially used to stabilize the voltage of the instrument power supply and suppress fluctuations to ensure the accuracy of automotive LED meters. However, there are still problems in the toughness and tear resistance of the shock-absorbing rubber of automotive LED instruments, which need to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a sealing member for automotive L...
