Abstract
Fiber for reinforcing rubber products, which comprises fiber coated with a coating film formed by a treating agent, wherein the treating agent comprises a rubber latex containing at least a vinylpyridine/styrene/butadiene terpolymer, a latex of an acrylonitrile/butadiene/styrene terpolymer, and a water-soluble condensate of resorcinol and formaldehyde.
Claims24
A reinforced rubber product comprising:
- a hydrogenated nitrile rubber composition;
- and
- at least one reinforcing fiber coated with first and second treating agents;
- wherein said hydrogenated nitrile rubber composition is reinforced with said at least one reinforcing fiber,
- wherein said first treating agent comprises:
- 100 parts by mass of a rubber latex containing at least a vinylpyridine/styrene/butadiene terpolymer,
- 15 to 70 parts by mass of a latex of an acrylonitrile/butadiene/styrene terpolymer, wherein, when the total of the copolymerized ratios of the respective comonomers is 100 mass %, acrylonitrile is from 20 to 40 mass %, butadiene is from 25 to 50 mass %, and styrene is from 30 to 40 mass %, and
- 5 to 15 parts by mass of a water-soluble condensate of resorcinol and formaldehyde,
- wherein said second treating agent comprises an uncured phenol resin and a rubber, and
- wherein said at least one reinforcing fiber is coated with a first coating film formed from said first treating agent, and wherein said first coating film is covered by a second coating film formed from said second treating agent, and
- wherein said uncured phenol resin is selected from the group consisting of a novolak, a resol and mixtures thereof.
