Problems solved by technology

However, on the other hand, polyester fibers have a disadvantage in that, compared with nylon fibers, their adhesion to rubber (which is the material of tires) is reduced, especially when exposed for a long time in a state of being embedded in a rubber composition. Adhesion loss at elevated temperatures is significant

Embodiment 1-1

[0160]A binder composition for organic fibers was prepared as a first treatment agent by the following method: While stirring water, 11.8 g of ETC-N615 (sorbitol polyglycidyl ether, chlorine content: 9.3% by weight) was added to 920 g of water , epoxy equivalent: 163, manufactured by Nagase ChemteX Corporation) as an epoxy compound, and 72.1 g of ε-caprolactam-blocked diphenylmethane diisocyanate aqueous dispersion (54% concentration) was added thereto as a blocked isocyanate.

[0161] Prepare the RFL liquid as rubber latex by the following method: Dilute 172g of Nipol 2518FS (manufactured by Nippon Zeon Co., Ltd., vinylpyridine-styrene-butadiene terpolymer water emulsion with 76g of water, total solid content concentration : 40.5%) and 73g of Nipol LX-112 (manufactured by Japan Zeon Co., Ltd., styrene-butadiene copolymer 41% water emulsion, total solid content concentration: 40.5%), and while slowly stirring the diluent , add 270g of resorcinol-formaldehyde initial condensati...

Embodiment 1-2

[0164] Process the organic fibers in the same manner as in Example 1-1, except that: use polyester-nylon hybrid cords (the composition of the cords: 1440-P / 1400-N (dtex), the twist of the cords: 34 (number of twists / 10 cm), cord diameter: 0.67 mm, number of warp yarns: 49 cords / 5 cm) as organic fibers. Initial adhesion and heat-resistant adhesion were measured on treated polyester-nylon hybrid cords (organic fibers). The results are shown in Table 1.

Embodiment 1-3

[0166] Treat organic fibers in the same manner as in Example 1-1, except that aramid cords are used (the composition of the cords: 1670 / 3 (dtex), the twist of the cords: 40 (number of twists / 10cm ), cord diameter: 0.85mm, number of warp yarns: 35 cords / 5cm) as organic fibers. Initial adhesion and heat-resistant adhesion were measured for the treated aramid cord (organic fiber). The results are shown in Table 1.

Abstract

An object of the present disclosure is to provide an adhesive composition for an organic fiber which has excellent heat-resistant adhesiveness that allows an organic fiber and a rubber composition tomaintain high adhesive force even when being exposed to high temperatures. The adhesive composition for an organic fiber contains: (a) an epoxy compound that is a sorbitol polyglycidyl ether and has achlorine content not greater than 9.6% by weight; and (b) a blocked isocyanate.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Japanese Patent Applications 2018-069803 and 2018-069807 filed in Japan on March 30, 2018. The entire contents of these Japanese patent applications are incorporated herein by reference. technical field [0003] The present invention relates to an adhesive composition for organic fibers, a treatment method for organic fibers, organic fibers and tires. Background technique [0004] Hitherto, various fibers such as polyester fibers, nylon fibers, and the like have been widely used as reinforcing materials for tires, and have been selectively used to suit required performance, various components, and the like. For example, polyester fibers have excellent dynamic properties (eg, high elastic modulus) and excellent dimensional stability. However, on the other hand, polyester fibers have a disadvantage in that, compared with nylon fibers, their adhesion to rubber (which is the materi...
