Abstract
Official abstract text for this publication.
In a friction transmission belt including a rubber layer forming a pulley contact surface, the rubber layer includes a rubber composition containing hydrophilic inorganic filler and a sliding-resistant material. The sliding-resistant material protrudes from the pulley contact surface, and is at least one of hydrophobic resin particles and hydrophobic resin fibers having an official regain of 0.4% or below, and in the rubber composition, a content of the hydrophilic inorganic filler with respect to 100 parts by mass of the rubber component is 35 parts by mass or more.
First claim
Opening claim text (preview).
What is claimed is: 1. A friction transmission belt comprising a rubber layer forming a pulley contact surface, wherein the rubber layer includes a rubber composition containing hydrophilic inorganic filler, and a sliding-resistant material, the hydrophilic inorganic filler includes at least silica not receiving coupling treatment, the sliding-resistant material protrudes from the pulley contact surface, and is hydrophobic resin particles having an official regain of 0.4% or below, in the rubber composition, a content of the sliding-resistant material with respect to 100 parts by mass of the rubber component is 35 parts by mass or more and 100 parts by mass or less, and in the rubber composition, a content of the hydrophilic inorganic filler with respect to 100 parts by mass of a rubber component is 35 parts by mass or more and 85 parts by mass or less. 2. The friction transmission belt of claim 1 , wherein in the rubber composition, the content of the hydrophilic inorganic filler with respect to 100 parts by mass of the rubber component is 45 parts by mass or more and 85 parts by mass or less. 3. The friction transmission belt of claim 1 , wherein in the rubber composition, the content of the hydrophilic inorganic filler with respect to 100 parts by mass of the rubber component is 55 parts by mass or more and 85 parts by mass or less. 4. The friction transmission belt of claim 1 , wherein the sliding-resistant material is made of polyethylene or polyethylene terephthalate. 5. The friction transmission belt of claim 1 , wherein the hydrophilic inorganic filler further comprises at least one of, montmorillonite, clay, and calcium carbonate. 6. The friction transmission belt of claim 1 , wherein in the rubber composition, a content of the silica with respect to 100 parts by mass of the rubber component is 30 parts by mass or more and 85 parts by mass or less. 7. The friction transmission belt of claim 1 , wherein the rubber composition does not contain a coupling agent. 8. The friction transmission belt of claim 1 , wherein the hydrophilic inorganic filler further comprises at least Ca-montmorillonite.
