Problems solved by technology

Although glass fiber has a series of excellent characteristics that meet the requirements of rubber skeleton materials such as high tensile strength, low elongation, heat resistance and dimensional stability, but because of its smooth surface and almost complete circular cross-section, the gap between fibers The cohesion force is small, and it is not easy to combine with the matrix. In addition, the wear resistance and kink resistance of the glass fiberboard are very poor. During the reciprocating motion, the fiber will break, fluff, or even peel off the matrix due to friction, resulting in product strength and life. reduce
Therefore, it is very difficult to directly use glass fiber as rubber reinforcement

Abstract

The invention discloses a glass fiber thread rope for reinforcing rubber, which can perform fiber drawing on raw materials, coating a treating compound, making fibrilla and combining strands into a rope. A single filament isolation step is added between the steps of fiber drawing and making the fibrilla; and a fibrilla gum dipping processing step is added on the fibrilla: controlling the tensile force of the fibrilla by a creel tension controller, putting the fibrilla into a rubber reinforcing pre-dipping gum groove at certain speed, coating rubber reinforcing pre-dipping gum in the rubber reinforcing pre-dipping gum groove on the surface of the fibrilla, and drying and rolling the fibrilla. The method provides a layer of protecting film on the surface of each fiber so that the fibers are isolated from one another, and can give play to the excellent characteristics of high tensile strength, large modulus of elasticity and low extensibility of the glass fiber.

Description

technical field [0001] The invention relates to a glass fiber cord for reinforcing rubber, in particular to a glass fiber cord for reinforcing rubber with high tensile strength and elastic modulus and low elongation. Background technique [0002] Rubber is a kind of polymer elastic material. Pure rubber products have low strength, so they must have fiber skeleton materials to play their functional roles. The role of these fiber skeleton materials in rubber products is to ① bear the load and ② maintain the dimensional stability of rubber products. . So far, it can be used as fiber skeleton material for rubber products. Its development history: cotton fiber - rayon - nylon fiber - polyester fiber - glass fiber, metal fiber and laborer fiber. [0003] Glass fiber has the characteristics of high strength, high modulus, low elongation, good dimensional stability, good temperature resistance, and excellent chemical stability. It is widely used in rubber products, especially rein...
