Embodiment 1

[0062] Embodiment 1: the manufacture method of RFL treating agent

[0063]Get 100 parts of vinylpyridine latex (trade name Nipol2518FS ZEON, 40% by weight, ZEON CORPORATION), 11.1 parts of chlorosulfonated polyethylene (commodity is [CSM450], 40% by weight, manufactured by Sumitomo Seika Chemicals), 6.7 parts RF polymer (INDSPEC company, 7% by weight), deionized water, and the above were mixed and reacted together to prepare an RFL treatment agent with a concentration of about 30%. (Note: the above components are parts by weight of solids)

Embodiment 2

[0064] Embodiment 2: the manufacture method of OVC treatment agent

[0065] 10 parts of chlorosulfonated polyethylene are used as halogenated compounds, 5 parts of polyisocyanate, 2 parts of p-, p'-bibenzoylbenzoquinone dioxime are used as vulcanizing agents, 5 parts of carbon black are used as inorganic filler materials, and toluene is used as Solvent, the OVC treatment agent with a concentration of 10% is prepared by mixing the above together. (Note: the above components are parts by weight of solids)

Embodiment 3-a

[0067] Take 600 strands of high-strength (S-grade glass fiber) glass fiber monofilaments with an average diameter of 7 microns, use the slurry mainly containing aminosilane coupling agent for sizing and assembly, and control the tension of the glass fiber bundles to 74g / strand. Through the wire winding device, after winding the wire, make it dry to obtain a fiber bundle silk cake with a mass of 3000g, then pull out the fiber bundle from the innermost side of the silk cake, remove about 100g of the part, and pull it from the remaining 2900g part 500M, through the impregnation tank filled with the RFL treatment agent prepared in Example 1, the drawn glass fiber bundles are continuously impregnated one by one. Make the RFL treatment agent adhere to the fiber bundle and penetrate into it. At this time, the tension of the glass fiber bundle was 70 g / strand.

[0068] Then pass the fiber bundle through an oven at 200-300° C. and continue heating for 1 minute to dry and solidify the ...

Abstract

The invention discloses a production process of fiberglass threads used for rubber reinforcement. The production process comprises the following steps: carrying out gum dipping of fiberglass bundles in turn by using RFL treating agent which uses rubber latex and the water-soluble condensation compound of resorcinol formaldehyde as main components; then, solidifying the fiberglass bundles to form fiberglass folded yarns containing inner gum dipped layers; carrying out primary twist of one or more than two fiberglass folded yarns containing the inner gum dipped layers; and finally, taking more than two fiberglass folded yarns after first twist to carry out stranding secondary twist, and the fiberglass folded yarns obtained after secondary twist are the fiberglass threads used for rubber reinforcement. The production process not only realizes effective gum dipping of fiberglass bundles, but also ensures the tensile strength of the fiberglass bundles, thereby increasing the eligible rate of the finished products of the fiberglass bundles.

Description

(1) Technical field [0001] The invention relates to a production process of a glass fiber rope for rubber reinforcement. The rope is used as a reinforcing material and is applied to the fields of various rubber products such as rubber conveyor belts and rubber tires mainly including synchronous belts. (2) Technical background [0002] Generally, glass fiber for reinforcement is used to improve the strength and durability of various rubber products such as rubber conveyor belts and rubber tires, mainly timing belts. Because the glass fiber for reinforcement has a dipping film formed by a rubber treatment agent, it not only improves the adhesion between the glass fiber and the rubber matrix of the rubber product, but also the dipping film protects the glass fiber itself. In turn, the durability of rubber products is improved. [0003] The rubber treatment agent used therein is an aqueous treatment agent mainly composed of resorcinol-formaldehyde condensate and rubber latex (h...
