Abstract

The invention discloses a sealing strip for a cab instrument desk. The sealing strip comprises the following raw materials in parts by weight: 20-50 parts of butadiene styrene rubber, 2-8 parts of tert-butyldimethylsilyl chloride, 5-12 parts of chlorosulfonated polyethylene, 1.5-3.5 parts of a cross-linking agent, 30-50 parts of a black mica compound, 5-15 parts of vermiculite power, 20-30 parts of talcum powder, 2-10 parts of expanded perlite, 2-8 parts of a multi-walled carbon nano tube, 3.5-4.5 parts of a compatilizer, 1-2 parts of ethylene glycol dimethacrylate, 0.5-1.5 parts of hydroquinone, 1-2 parts of p-phenylenediamine and 2-3 parts of magnesium stearate. The sealing strip for the cab instrument desk has excellent high temperature resistance, anti-aging property, excellent sealing effect, promoted comfortable sensation of the passenger, difficulty in falling off, easily available raw materials and low cost.

Description

Technical field [0001] The invention relates to the technical field of sealing strips, in particular to a sealing strip for a cab instrument panel. Background technique [0002] In the existing cab instrument panel sealing structure, the sealing strip is laid between the instrument panel and the front windshield. The sealing strip is easy to slide and fall off due to long-term exposure to the sun, resulting in a loose seal between the instrument panel and the front windshield and easy dust The bottom of the cab enters the cab, which seriously affects the driver’s ride comfort; at the same time, it affects the aesthetics of the cab and affects the driver’s subjective evaluation of the car. How to improve the high temperature and aging resistance of the sealing strip needs to be solved urgently. Summary of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a cab instrument panel sealing strip, which has excell...
