Embodiment approach 1

[0062] (ribbed belt B)

[0063] figure 1 And 2 represents the V-ribbed belt B according to Embodiment 1. The V-ribbed belt B according to Embodiment 1 is, for example, an endless power transmission member used in an auxiliary drive belt transmission or the like installed in an engine room of an automobile. The V-ribbed belt B according to Embodiment 1 has, for example, a belt length of 700 to 3000 mm, a belt width of 10 to 36 mm, and a belt thickness of 4.0 to 5.0 mm.

[0064] The V-ribbed belt B according to Embodiment 1 includes a V-ribbed belt main body 10 made of rubber. An adhesive rubber layer 12 in the middle and a back rubber layer 13 on the outer peripheral side of the belt. A core wire 14 is embedded in a middle portion in the thickness direction of the adhesive rubber layer 12 of the V-ribbed belt main body 10 so as to form a helix having a pitch in the belt width direction. In addition, instead of the back rubber layer 13 , a back reinforcement cloth may be pro...

[0114] [Test Evaluation 1]

Embodiment 1-1

[0117] CR latex (trade name: Chloroprene 842A manufactured by Showa Denko Co., Ltd.) is mixed with an aqueous dispersion of cellulose microfibers (manufactured by Daio Paper Co., Ltd.) produced by mechanical defibration, and the water is vaporized to produce cellulose microfibers / CR masterbatch.

[0118] Then, CR (manufactured by Showa Denko Co., Ltd., trade name: Chloroprene GS) was masticated, and a masterbatch was put therein and kneaded. Regarding the input amount of the masterbatch, when the total amount of CR is 100 parts by mass, the content of the cellulose-based ultrafine fibers is 20 parts by mass.

[0119] Then, CR and cellulose microfibers were kneaded, and 20 parts by mass of carbon black HAF (trade name: SEAST3 manufactured by Tokai Carbon Co., Ltd.) , 5 parts by mass of aromatic polyamide staple fiber (Technora (registered trademark) produced by Teijin Corporation), 5 parts by mass of oil (trade name: SUNPAR2280 produced by Japan's SUN Petroleum Co., Ltd.), 5 ...

Abstract

This transmission belt simultaneously satisfies a plurality of prescribed characteristics. The belt B is a transmission belt that is wound around pulleys and transmits power. Said belt has a layer comprising a rubber composition that contains cellulose-based fine fibers, and short fibers (16) having an average diameter of 1[mu]m or greater.

Description

technical field [0001] The present invention relates to transmission belts. Background technique [0002] Short fibers are blended into the rubber composition constituting the rubber layer of the transmission belt. For example, Patent Document 1 discloses that at least the compression layer of the V-belt is made of a rubber composition containing carbon black and short fibers. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2014-167347 [0006] Transmission belts are required to have various characteristics such as wear resistance, coefficient of friction, and suppression of adhesive wear. When carbon black and short fibers are added to the rubber composition constituting the belt for reinforcement, if certain properties are satisfied by adjusting the compounding amount, other properties tend to be deteriorated. Contents of the invention [0007] Therefore, an object of the present invention is to provi...
