[0182] [Surface layer and compression rubber layer]

[0183] For the surface layer and compression rubber layer forming the drive surface (contact surface with the pulley) of the belt, the rubber composition for the surface layer and compression rubber layer of the formulation shown in Table 1 was kneaded at 140° C. using a Banbury mixer. , was rolled to a predetermined thickness with a calender roll, and the resulting sheet was used. The thickness of the sheet for the surface layer was adjusted so that the thickness of the surface layer was 500 μm. In addition, in Comparative Examples 1 and 5, no surface layer was formed, and in Comparative Example 8, a surface layer described later was formed.

Abstract

The present invention relates to a friction transmission belt comprising a compressed rubber layer formed from a cured product of a rubber composition, at least a portion of which has a friction transmission surface capable of coming into contact with a pulley, a surface layer containing a cured product of a rubber composition containing a polyvinylpyrrolidone resin and an elastomer component is laminated on the surface of the friction transmission surface.

Description

technical field [0001] The present invention relates to a friction transmission belt (particularly a V-ribbed belt) used in the driving of automobile engine auxiliary equipment, etc., and in particular relates to a belt capable of stabilizing the friction state of the friction transmission surface while maintaining the transmission capacity and fuel saving performance so as to improve the resistance to friction. Noise generating friction drive belt. Background technique [0002] In the field of the rubber industry, high functionality and high performance are desired especially for automotive parts. As one of the rubber products used in such automobile parts, there is a friction transmission belt widely used in power transmission for driving auxiliary machines such as air compressors and alternators of automobiles. As such a belt, a V-ribbed belt is known in which ribs are provided along the belt length direction. However, the V-ribbed belt requires noise resistance in addit...
