Problems solved by technology

However, the rubber composition prepared by mixing H-NBR with excellent heat resistance and high saturation as the main component with a peroxide vulcanizing agent will result in insufficient adhesion
Therefore, when the conventional glass fiber cord for reinforcing rubber products is used in combination with a rubber composition whose main component is highly saturated H-NBR, the final rubber products such as synchronous belts have insufficient heat resistance and bending fatigue resistance. question
[0006] In addition, when the above-mentioned reinforced rubber products are bonded to the H-NBR rubber composition with glass fiber cords, because the adhesion is easily reduced in a water-contact environment, the final rubber products such as synchronous belts have poor water resistance. question

Embodiment 1

[0045] Concentration is the preparation of the 1st treatment agent (RFL treatment agent) of 30%wt: with 100 parts of ternary copolymer latex (trade name [Pyratex], 40wt%, NIPPONAA&L company produces), 50 parts of styrene-butadiene Diene latex (trade name [NIPOL 2570X5], 40 wt%, Japan ZEON Co.), 10 parts of RF condensate (manufactured by INDSPEC Co., 7 wt%) and deionized water were mixed. In addition, the above-mentioned parts of each component are parts by weight of solid content.

[0046] Concentration is the preparation of the 2nd treatment agent (OVC treatment agent) of 10wt%: Chlorosulfonated polyethylene (trade name [Hypalon], manufactured by Du Pont Company) 10 parts, polyisocyanate (trade name [MR-200], manufactured by NIPPON POLYUERTHANE ) 5 parts, p, p'-bibenzoylbenzoquinone dioxime 2 parts as a vulcanizing agent, 5 parts of carbon black as an inorganic filler, and mixed together with toluene as a solvent. The above parts are parts by weight of solid content.

Embodiment 2

[0051] According to the process described in Example 1, the difference is that the RFL treatment agent of the following formula is used instead of the RFL treatment agent in Example 1 for preparation, and the glass fiber cord for rubber reinforcement of the present invention can be obtained.

[0052] The prescription of the RFL treatment agent of described concentration 30% consists of: with 100 parts of terpolymer latex (trade name [Pyratex], 40wt%, NIPPONA A&L company produces), 50 parts of styrene-butadiene latex (trade name [NIPOL 2570X5], 40 wt%, Japan ZEON Co.), 5 parts of RF condensate (manufactured by INDSPEC Co., 7 wt%) and deionized water were mixed. In addition, the above-mentioned parts of each component are parts by weight of solid content.

Embodiment 3

[0054] According to the process described in Example 1, the difference is that the RFL solution of the following formula is used instead of the RFL solution in Example 1 for preparation, and the glass fiber cord for rubber reinforcement of the present invention can be obtained.

[0055] The prescription of the RFL treatment agent of described concentration 30% consists of: with 100 parts of terpolymer latex (trade name [Pyratex], 40wt%, NIPPONA A&L company produces), 50 parts of styrene-butadiene latex (trade name [NIPOL 2570X5], 40 wt%, Japan ZEON Co.), 15 parts of RF condensate (manufactured by INDSPEC Co., 7 wt%) and deionized water were mixed. In addition, the above-mentioned parts of each component are parts by weight of solid content.

Abstract

The invention discloses an RFL treating agent and application thereof. The RFL treating agent at least contains vinyl pyridine-styrene-butadiene terpolymer rubber latex, styrene-butadiene copolymer rubber latex and resorcinol-formaldehyde condensate; and based on 100 portions of the solid content of the vinyl pyridine-styrene-butadiene terpolymer rubber latex, the solid content of the styrene-butadiene copolymer rubber latex is 40 to 60 portions, and the solid content of the resorcinol-formaldehyde condensate is 5 to 15 portions. The RFL treating agent can be used for preparing a rubber reinforcing glass fiber cord; and because the RFL treating agent contains the resorcinol-formaldehyde condensate in a specific ratio, the rubber reinforcing glass fiber cord has both heat resistance and water resistance, can be used as a reinforcing material, is applied to rubber products such as synchronous belts for automobile engines and the like, and can further improve the durability when used under high-temperature and high-humidity environments.

Description

(1) Technical field [0001] The invention relates to an RFL treatment agent, which is mainly used for preparing glass fiber cords for reinforcing rubber products, and the cords are especially suitable as reinforcing materials for various rubber products such as rubber conveyor belts and rubber tires based on synchronous belts. (2) Background technology [0002] As far as the industry knows, the general use of glass fibers for reinforcement can improve the strength and durability of various rubber products such as rubber conveyor belts and rubber tires, mainly synchronous belts. Since the glass fiber cord for reinforcement has a dipping film formed by a rubber treatment agent, it not only improves the adhesion between the fiber and the rubber matrix of the rubber product, but also the dipping film protects the glass fiber itself. , thereby improving the durability of rubber products. And the main component of this treating agent is that resorcinol formaldehyde condensate and ...
