Problems solved by technology

[0006] The RFL treatment agents described in the above-mentioned Patent Document 1 and Patent Document 2 still have the following problems: the drive belts such as synchronous belts on automobile engines need to be used in high-humidity environments in addition to heat resistance when used in high-temperature environments water resistance
[0010] However, the above weight ratio makes the content of heat-resistant chlorosulfonated polyethylene latex smaller, resulting in insufficient heat resistance of the glass fiber cord for reinforcement, and the durability of the final synchronous belt when used in a high-temperature environment not enough
Moreover, according to the above weight ratio, the proportion of vinylpyridine-styrene-butadiene terpolymer is significantly larger, and the viscosity of the reinforced glass fiber cord is too high, which is not conducive to production.

Embodiment 1

[0062] Concentration is the preparation of the RFL treating agent of 30%wt: with 100 parts of terpolymer latex (trade name [Pyratex], 40wt%, NIPPONA A&L company produces), 40 parts of chlorosulfonated polyethylene latex (trade name [CSM450], 40 wt%, manufactured by Sumitomo Seika Chemicals), 8 parts of RF condensate (manufactured by INDSPEC, 7 wt%) and deionized water were mixed. In addition, the above-mentioned parts of each component are parts by weight of solid content.

[0063] Concentration is the preparation of the OVC treating agent of 10wt%: 10 parts of chlorosulfonated polyethylene (trade name [Hypalon], manufactured by DuPont Co.), 5 parts of polyisocyanate (trade name [MR-200], manufactured by NIPPON POLYUERTHANE), p, 2 parts of p'-bibenzoylbenzoquinone dioxime is used as vulcanizing agent, 5 parts of carbon black is used as inorganic filler, and mixed together with toluene as solvent. The above parts are parts by weight of solid content.

Embodiment 2

[0068] 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.

[0069] The formula of described RFL treatment agent consists of: 100 parts of terpolymer latex (trade name "Pyratex", manufactured by NIPPONA & LINC.), 36 parts of chlorosulfonated polyethylene latex (trade name "CSM450", SUMITOMO SEIKA CHEMICAL CO.LTD), 8 parts of RF polycondensate (INDSPEC company, 7wt%) and deionized water were stirred to obtain a 30% concentration of the first treatment agent. The above-mentioned parts are parts by weight of solid content.

Embodiment 3

[0071] 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.

[0072] The formula of described RFL treatment agent consists of: 100 parts of terpolymer latex (trade name "Pyratex", manufactured by NIPPONA & LINC.), 45 parts of chlorosulfonated polyethylene latex (trade name "CSM450", SUMITOMO SEIKA CHEMICAL CO.LTD), 8 parts of RF polycondensate (INDSPEC company, 7wt%) and deionized water were stirred to obtain a 30% concentration of the first treatment agent. The above-mentioned parts are parts by weight of the solid content of each component.

Abstract

The invention discloses an RFL treatment agent and application thereof. The RFL treatment agent at least comprises vinylpyridine-styrene-butadiene copolymer latex, halogenated polymer latex and water-soluble condensate of resorcinol and formaldehyde; and by taking the solid content of the vinylpyridine-styrene-butadiene copolymer latex as 100 portions, the solid content of the halogenated polymerlatex is 36 to 45 portions and the solid content of the water-soluble condensate of resorcinol and formaldehyde is 4 to 12 portions. When the RFL treatment agent is used for preparing rubber product reinforcing glass cords, the prepared rubber product reinforcing glass cords have good heat and water resistance, and the durability and water resistance of various rubber products such as rubber conveyor belts giving priority to synchronous belts, rubber tyres and the like which are prepared from the glass cords serving as a reinforcing material are greatly improved when the rubber products are used in the environment of high temperature and high humidity.

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 ...
