Abstract
Official abstract text for this publication.
Provided by the present invention are: a non-asbestos frictional material composition containing a binder, an organic filler, an inorganic filler, and a fiber substrate, wherein, in the non-asbestos frictional material composition, content of a copper is 5% or less by mass as a copper element, content of a metal fiber other than a copper fiber and a copper alloy fiber is 0.5% or less by mass, and a titanate salt is contained therein with antimony trisulfide or zinc powders, with content of the titanate salt being in the range of 10 to 35% by mass; and a frictional material and a friction member that use the said non-asbestos frictional material composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A non-asbestos frictional material composition comprising a binder, an organic filler, an inorganic filler, and a fiber substrate, wherein, in the non-asbestos frictional material composition, content of a copper is 5% or less by mass as a copper element, content of a metal fiber other than a copper fiber and a copper alloy fiber is 0.5% or less by mass, and a titanate salt and antimony trisulfide are comprised therein with content of the titanate salt being in the range of 13 to 35% by mass. 2. The non-asbestos frictional material composition according to claim 1 , wherein content of the antimony trisulfide is in the range of 1 to 10% by mass. 3. The non-asbestos frictional material composition according to claim 1 , wherein the titanate salt is in the form of a scale, a plate, or a pillar. 4. The non-asbestos frictional material composition according to claim 1 , wherein the titanate salt is a lithium potassium titanate or a magnesium potassium titanate. 5. A frictional material formed by molding the non-asbestos frictional material composition according to claim 1 . 6. A friction member formed by using a backing plate and the frictional material formed by molding the non-asbestos frictional material composition according to claim 1 . 7. The non-asbestos frictional material composition according to claim 1 , wherein content of the titanate salt being in the range of 13 to 24% by mass. 8. A frictional material formed by molding the non-asbestos frictional material composition according to claim 7 . 9. A friction member formed by using a backing plate and the frictional material formed by molding the non-asbestos frictional material composition according to claim 7 . 10. The non-asbestos frictional material composition according to claim 1 , wherein content of the titanate salt being in the range of 14 to 20% by mass.
