[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 object of the present invention is to provide a rubber-reinforcing polyester that has good adhesion to ethylene-α-olefin-non-conjugated diene copolymer rubber compounds and improves process passability in the manufacture of automotive hoses and other products Fiber cord. The solution is a polyester fiber cord for rubber reinforcement, which is characterized in that an adhesive is applied to the polyester fiber to which a polyepoxy compound has been applied in advance, and the adhesive contains at least isophthalic acid. The phenol-formaldehyde-rubber latex (A), the blocked polyisocyanate compound (B) and the halogenated phenol derivative (C), the rubber latex which is a component of the adhesive agent, contains in 100 parts by mass of the total solid content of the rubber latex The mixture of neoprene latex (D) and polybutadiene rubber latex (E) is 80-100 parts by mass, and the mixing ratio of (D) and (E) is (D) / (E)=80 / 20-20 / 80 (mass ratio of solid components).

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...
