Abstract
Official abstract text for this publication.
A power transmission belt at least includes a bottom rubber layer. A rubber composition for forming the bottom rubber layer contains a rubber component, cellulose fine fibers, and short fibers. The cellulose fine fibers have an average diameter from 1 nm to 200 nm, and the rubber composition contains 0.5 parts by mass or more of the cellulose fine fibers relative to 100 parts by mass of the rubber component. The short fibers have an average diameter from 5 μm to 30 μm, and the rubber composition contains 1 part by mass or more of the short fibers relative to 100 parts by mass the rubber component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A power transmission belt at least comprising a bottom rubber layer, wherein a rubber composition for forming the bottom rubber layer contains a rubber component, cellulose fine fibers, and short fibers, the cellulose fine fibers have an average diameter from 1 nm to 200 nm, and the rubber composition comprises from 1 part by to 20 parts by mass of the cellulose fine fibers relative to 100 parts by mass of the rubber component, and the short fibers have fiber lengths from 0.5 mm to 5.0 mm and an average diameter from 8 μm to 25 μm, and the rubber composition comprises from 5 parts by mass to 30 parts by mass of the short fibers relative to 100 parts by mass the rubber component. 2. The power transmission belt of claim 1 , wherein the cellulose fine fibers have an average diameter from 2 nm to 50 nm. 3. The power transmission belt of claim 1 , wherein the cellulose fine fibers are produced by chemical defibration. 4. The power transmission belt of claim 1 , wherein the rubber component is at least one of an ethylene propylene copolymer, an ethylene-propylene-diene terpolymer, an ethylene-octene copolymer, and ethylene-butene copolymer, a chloroprene rubber, a chlorosulfonated polyethylene rubber, or a hydrogenated acrylonitrile rubber.
