Embodiment 1

[0021] A new type of rock wool is composed of the following raw materials in parts by weight: 55 parts of basalt, 30 parts of limestone, 15 parts of aluminum silicate, and 5 parts of fluorite.

Embodiment 2

[0023] A new type of rock wool is composed of the following raw materials in parts by weight: 60 parts of basalt, 20 parts of limestone, 10 parts of aluminum silicate, 5 parts of shale, and 5 parts of diatomite.

Embodiment 3

[0025] A new type of rock wool is composed of the following raw materials in parts by weight: 60 parts of basalt, 25 parts of limestone, 10 parts of aluminum silicate, 3 parts of fluorite, 3 parts of shale, and 4 parts of diatomite.

[0026] Compared with the prior art, the novel rock wool of the present invention has the following advantages:

[0027] (1) The product has low hardness and good wear resistance, which can reduce the wear of friction materials;

[0028] (2) It has good high temperature resistance and extremely low thermal conductivity. It can effectively reduce the thermal decay and expansion of other low-temperature materials in the friction material when it is attached to the surface of the friction material, and improve the resistance of the friction material in the process of manufacture and use. stability;

[0029] (3) Strong adsorption, can absorb various powdery materials, and enhance the firmness of friction materials;

[0030] (4) Easy to disperse, les...

Abstract

The invention discloses a novel rock wool, which consists of the following raw materials according to parts by weight: 55-65 parts of basalt, 20-30 parts of limestone, 10-15 parts of aluminum silicate and 5-10 parts of auxiliary material. The novel rock wool product is low in hardness, good in abrasion resistance, capable of reducing abrasion of the friction material, excellent in high-temperature resistant performance and quite low in heat conductivity coefficient; the novel rock wool, attached on the surface of the friction material, can effectively reduce heat fading property and expansibility of other low-temperature materials in the friction material and improve the stability of the friction material in the processes of manufacturing and using; with comparatively strong adsorbability, the novel rock wool can adsorb various powdery materials, so the stability of the friction material is enhanced; and the novel rock wool is easy to disperse so as to reduce the dust which is irritative to the skin and is favorable for the body health.

Description

technical field [0001] The invention relates to the field of friction materials, in particular to a novel rock wool. Background technique [0002] Rock wool, also known as rock wool, is a type of mineral wool. Fluffy short fibers made from natural rocks and minerals. Rock wool is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc., which are melted and fiberized at high temperature. In the 1970s, it was widely used in metallurgy, machinery, building materials, petroleum, and chemical industries. The natural rock, ore and other raw materials are melted in a cupola or other pool kiln (temperature below 2000 ℃), blown and quenched into a fibrous shape with a pressure of 50 atmospheres. Or use the silk spinning method to drop the molten liquid flow on the multi-stage rotary rotor, and spin it into fibers by centrifugal force, with a diameter of generally 3-9 microns and a bulk density of 50-200 kg / m 3 , the thermal conductivit...
