Abstract
Disclosed is a low metal automobile brake block, which is characterized by being composed of components with following parts by weight: resin takes 5-8 parts, rubber powder takes 1-2 parts, friction powder takes 1-2 parts, steel fiber takes 7-9 parts, mineral fiber takes 13-15 parts, petroleum coke takes 11-14 parts, permanent white takes 36-38 parts, crystalline flake graphite takes 3-4 parts, aluminum oxide takes 2-3 parts, ferric sulfide takes 3-4 parts, and ferrous powder takes 8-9 parts, thereby the low metal automobile brake block can reduce pollution, is not easy to rust, reduces noise, and is particularly adaptable for automobiles.
Description
Technical field:
The present invention relates to a kind of brake block, particularly a kind of low-metal vehicle brake flat.
Background technique:
At present, automobile is as the main traffic tool, in people's life, bringing into play more and more important effect, development along with car industry, people are more and more higher to the requirement of vehicle safety, travelling comfort, the feature of environmental protection, the braking of this and automobile has confidential relation, and automobile brake sheet is the key position of braking, the performance direct relation of brake block the performance of braking, the brake block that China's automobile uses is divided into the asbestos friction material brake block by the friction material of its use, asbestos brake lining mainly contains asbestos, and asbestos content is about 30-45%, and is seriously polluted; Semi-metallic brake pad invar fiber equal size height gets rusty easily, produces noise.
Summary of the invention:
Purpose of the present invention is exactly that a kind of low-metal vehicle brake flat that can reduce pollution, be difficult for getting rusty, reducing noise will be provided.
The object of the present invention is achieved like this: a kind of low-metal vehicle brake flat, its feature is made up of following components in part by weight: resin 5-8 part, rubber powder 1-2 part, friction powder 1-2 part, Steel Fibre 7-9 part, mineral fibre 13-15 part, petroleum coke 11-14 part, barium sulphate 36-38 part, crystalline flake graphite 3-4 part, aluminium oxide 2-3 part, iron sulfide 3-4 part, iron powder 8-9 part.
The original material process of the present invention:
Resin is by phenol and formaldehyde condensation polymer and make;
Rubber powder is made from the rubbery chip that junked tire peels;
Mineral fibre is made by natural inorganic fiber;
Petroleum coke is to form the charcoal body thing that granular, column or needle-like constitute by small graphite crystallization, and the petroleum coke component is a hydrocarbon, carbon containing 90-97%, and hydrogeneous 1.5-8% also contains nitrogen, chlorine, sulphur and heavy metal compound;
Crystalline flake graphite is made by carbon.
The present invention compared with prior art has the following advantages:
Owing to adopt above various components, solved because of asbestos content height, seriously polluted and invar fiber equal size height gets rusty easily, produces problems such as noise, thereby can reduce pollution, is difficult for getting rusty, reducing noise.
Embodiment:
Mode of execution 1: get 5.5 parts of resins, 1 part of rubber powder, 1 part in powder of friction, 7 parts of Steel Fibres, 13 parts of mineral fibre, 11.5 parts of petroleum cokes, 36 parts in barium sulphate, 3 parts of crystalline flake graphites, 2 parts in aluminium oxide, 3 parts in iron sulfide, 8 parts of iron powders, use high speed mixer or plough type batch mixer, according to certain mixing time and weighing procedure operation.
Mode of execution 2: get 7 parts of resins, 1.5 parts of rubber powders, 1.5 parts in powder of friction, 8 parts of Steel Fibres, 14 parts of mineral fibre, 13 parts of petroleum cokes, 37 parts in barium sulphate, 3.5 parts of crystalline flake graphites, 2.5 parts in aluminium oxide, 3.5 parts in iron sulfide, 8.5 parts of iron powders, making method is with real mode 1.
Mode of execution 3: get 8 parts of resins, 2 parts of rubber powders, 2 parts in powder of friction, 9 parts of Steel Fibres, 15 parts of mineral fibre, 14 parts of petroleum cokes, 38 parts in barium sulphate, 4 parts of crystalline flake graphites, 3 parts in aluminium oxide, 4 parts in iron sulfide, 9 parts of iron powders, making method is with mode of execution 1.
