Embodiment 1

[0126] Add resorcinol-formaldehyde initial condensate: "Sumicanol" 700 (S)" (registered trademark) (manufactured by Sumitomo Chemical Co., Ltd., 65% aqueous solution) to an aqueous solution of sodium hydroxide, and stir sufficiently to disperse it. Formaldehyde was added to the dispersion and mixed uniformly, and as a result, the molar ratio of resorcinol / formaldehyde was 1 / 2, aged at 25° C. for 4 hours to obtain a solution of resorcinol-formaldehyde condensate. Then , 60 parts by mass of neoprene latex ("ショウプレン" (registered trademark) 750 (produced by Showa Denko, surface tension 39mN / m, average particle diameter 120nm) and 40 parts by mass of polybutadiene rubber latex ("ニッポール " (registered trademark) LX-111A (manufactured by Nippon Zeon Co., Ltd., average particle diameter 300nm) was mixed to prepare a rubber latex mixed solution. The aforementioned rubber latex mixed solution was mixed with the aforementioned resorcinol-formaldehyde condensate solution , so that the solid c...

Abstract

The present invention addresses the problem of providing a polyester fiber cord for reinforcing rubber, said polyester fiber cord exhibiting good adhesion to an ethylene-alpha-olefin-unconjugated diene copolymer rubber blend and improving the processability during the production of a product such as an automotive hose. As a means for solving the above problem, provided is a polyester fiber cord for reinforcing rubber that is obtained by adding, to a polyester fiber to which a polyepoxide compound has been preliminarily added, an adhesive comprising at least a resorcin-formalin-rubber latex (A), a blocked polyisocyanate compound (B) and a halogenated phenol derivative (C), characterized in that: the rubber latex that is a component of the adhesive contains 80-100 parts by mass, per 100 parts by mass of the total solids of the rubber latex, of a mixture of a chloroprene rubber latex (D) with a polybutadiene rubber latex (E); and the mixing ratio of (D) to (E) [(D)/(E): solid content mass ratio] is from 80/20 to 20/80.

Description

technical field [0001] The present invention relates to a polyester fiber cord for rubber reinforcement. Specifically, it relates to a polyester fiber cord for rubber reinforcement having good adhesion to an ethylene-α-olefin-non-conjugated diene copolymer rubber compound (hereinafter referred to as "EPDM-based rubber"), Moreover, the process passability in the manufacture of products such as automobile hoses has been improved, that is, the resorcinol-formaldehyde-rubber latex (hereinafter referred to as "RFL") used as an adhesive on the surface of polyester fiber cords has been improved. situation.) of falling off. Background technique [0002] Polyester fibers represented by polyethylene terephthalate fibers have been used as rubber soft fibers in the past because of their physical properties such as high strength and modulus, low elongation and creep, and excellent fatigue resistance. The pipe is used with reinforcing fibers. However, since the surface of the polyester...
