Description

A kind of resistant to elevated temperatures automobile disc brake pad

Technical field

The present invention relates to a kind of resistant to elevated temperatures automobile disc brake pad.

Background technique

Disk type brake has one to fix with tire and synchronizedly rotates to obtain circular disc, uses oil pressure to promote brake block clamping roudnel, produce frictional force is braked by contact during brake.Disc brake pad (dish) is divided into ordinary disc-type and ventilated disc.At present, automobile brake friction plate uses antimonous sulfide in a large number, also exists containing heavy metal, to environment; Simultaneously common brake block, when high temperature friction, there will be slight ruckbildung, sometimes because friction is comparatively frequent, occurs the taste burnt, well can not play braking action.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of automobile disc brake pad, has good resistance to high temperature, and heat radiation is very fast simultaneously, and wear resistance is better, long service life.

For solving prior art problem, technological scheme provided by the invention is, a kind of resistant to elevated temperatures automobile disc brake pad, and it is made up of the raw material of following parts by weight:

Attapulgite 9-16 part, rutile type titanium white 5-8 part, cross-linked modifier 1-5 part, methyl phenyl siloxane branched chain type prepolymer 6-11 part, barite 4-8 part, steel wool fiber 2-6 part, Nitrile Rubber phenol 3-9 part, thermosetting resin 6-10 part, carbon fiber 2-6 part, barium sulphate 5-10 part, potassium titanate fibre 7-10 part, mica 1-4 part, copper powder 4-6 part, resin 1-4 part, cashew nut shell oil Frication powder 6-14 part.

The invention has the beneficial effects as follows: automobile disc brake pad of the present invention, have good resistance to high temperature, heat radiation is very fast simultaneously, and wear resistance is better, long service life.
