Description
Technical field
The present invention relates to a kind of friction material, more particularly to a kind of ceramet friction material.
Background technology
At present, ceramic metallic material is increasingly used in our life, because ceramic metallic material has pottery concurrently
A variety of advantages of porcelain and metal and favored by user.But the ceramic metallic material of prior art is due to formula and selection
Material etc. easily limits, and the performance of its manufactured ceramic metallic material is general, it is impossible to high temperature resistant, corrosion-resistant, water-impervious and strong
Deficiency etc. is spent, because its development also receives certain restriction, is particularly applied on the brake block of automobile.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of ceramet friction material.
The technical solution adopted by the present invention is:
A kind of ceramet friction material, by weight, it is made up of the raw material of following number:The iron oxide of 15-20 parts, 50-
80 parts of kaolin, the nano silicon of 8-15 parts, the quartz of 5-6 parts, the paraffin of 8-10 parts, the boron glass of 0.5-1.5 parts,
The magnetite of 3-5 parts, the barium hydroxide of 3-5 parts, the zinc oxide of 6-8 parts, the aluminium nitride of 4-6 parts.
Further, by weight, it is made up of the raw material of following number:The iron oxide of 18-20 parts, the height of 60-70 parts
Ridge soil, the nano silicon of 10-15 parts, 5.5 parts of quartz, 9 parts of paraffin, 1 part of boron glass, the magnetite of 3-5 parts, 3-4
