Material of automobile brake pedal and preparation method thereof

Abstract

The invention discloses a material of an automobile brake pedal. The material is prepared from the following materials in parts by weight: 66-70 parts of polyamide, 12-14 parts of polyphenylene sulfide, 22-24 parts of glass fiber, 15-20 parts of carbon black, 11-14 parts of aluminum hydroxide, 7-12 parts of methylaluminoxane, 3-5 parts of zirconocene dichloride, 22-24 parts of p-phenylenediamine, 6-9 parts of ethoxyquinoline, 6-12 parts of maleic anhydride, 12-18 parts of polybutadiene latex, 1-2 parts of styrene-butadiene latex, 14-18 parts of borax, 3-8 parts of epoxidized soybean oil, 7-8 parts of ammonium polyphosphate, 11-14 parts of zinc borate, 20-22 parts of dioctyl phthalate, 7-10 parts of potassium titanate whisker and 11-16 parts of benzoyl peroxide. The material of an automobile brake pedal disclosed by the invention has the advantages of high structural strength, wear resistance, aging resistance and long service life.

Description

technical field [0001] The invention relates to a material of an automobile brake pedal and a preparation method thereof. Background technique [0002] my country's latest national standard "Terms and Definitions of Vehicles and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-loaded vehicle driven by power with 4 or more wheels, mainly used Used for: carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. Of course, the low-end technology and meager profits of commercial vehicle parts companies are also related to the characteristics of commercial vehicles. A commercial vehicle is different from a passenger vehicle. A commercial vehicle is an investment tool, and customers pay more attention to its cost performance when purchasing. As long as it is durable, it is enough that the cost of acquisition is effectively offset by the value created in use. Therefore, commercial vehicles have fewer re...

Problems solved by technology

For a certain period of time, auto parts companies have fallen into two vicious circles that are difficult to get rid of: one is that local protectionism has seriously caused one-to-one marketing by parts companies, and their market development capabilities are insufficient to form a scale effect. There is no decision-making power in the industrial chain, and it is completely reduced to a foundry; enterprises indulge in low-price competition and do not pay attention to intellectual property protection, which in turn increases local protectionism

The second vicious circle is that low technical content leads to low profits, which in turn makes R&D funds unsustainable, which in turn leads to low technical content

[0003] The existing automobile brake pedal is not high in structural strength as an automobile part and needs to be used in conjunction with metals. It is not resistant to wear and aging and has a short service life.
