Embodiment 1

[0016] Embodiment 1, this product is by 25% brucite fiber; 5% metal fiber; 20% plant fiber; 20% phenolic resin; 12% barium sulfate; 5% feldspar; 6% tire powder; 5% fluorite; 1% alumina; 1% zinc stearate.

Embodiment 2

[0017] Embodiment 2, this product is by 45% brucite fiber; 5% metal fiber; 15% modified phenolic resin; 14% barium sulfate; 5% feldspar; 8% tire powder; 6% Fluorite; 1% aluminum oxide; 1% zinc stearate.

Embodiment 3

[0018] Embodiment 3, this product is by 37% brucite fiber; 5% metal fiber; 8% plant fiber; 17% modified phenolic resin; 13% barium sulfate; 6% feldspar; 7% tire powder; 5% fluorite; 1% aluminum oxide; 1% zinc stearate. This embodiment is a preferred example.

[0019] see figure 1 , The technological process in the prior art is: sequentially including raw material preparation, batching, mixing, thermoforming, semi-finished product inspection, heat treatment, grinding, appearance inspection, and packaging procedures.

[0020] see figure 2 , the present invention adds a normal-temperature billet-making process between mixing and hot-pressing forming, that is, the mixture is made into a parison at normal temperature, and hot-pressing is performed when the parison is uniform in thickness and meets the requirements.

[0021] During specific implementation, the materials prepared according to the weight percentage are sequentially completed through raw material preparation, batch...

Abstract

The present invention relates to pollution-less non-metal friction material and its preparing process. The pollution-less non-metal friction material consists of brucite fiber 25-45 wt%, reinforcing fiber 5-25 wt%, adhesive 15-20 wt% and friction performance regulator 25-35 wt%. The preparing process features the normal temperature blank producing step increased between the mixing and hot pressing steps. The friction material may be used as the foundation material for clutch plate and brake lining plate.

Description

Technical field: [0001] The invention belongs to a pollution-free non-metallic friction material and a preparation process thereof. Background technique: [0002] Friction material is the basic material for manufacturing various clutch faces and brake linings. In the prior art, asbestos friction material is made of asbestos fiber as the base material, and is compounded by adding adhesive and friction performance modifier. High, not wear-resistant. Because asbestos is recognized as a carcinogen in the world and has great harm to the human body, it was approved by the State Bureau of Quality and Technical Supervision on January 8, 1999, and stipulated in the national standard GB12676-1999 of the People's Republic of China. From October 1, 2003 Asbestos is prohibited in automobile brake linings. Another semi-metallic friction material in the prior art has the defects of scratching the counterpart and generating noise pollution. At present, there are no related reports and pr...
