Abstract

The invention provides a preparation method of low-degradation tension glass fibers. The preparation method comprises the following steps: 1S, preparing an impregnating agent: controlling the mass ratio of a coupling agent and a film forming agent to be (1: 25) to (1: 7), and controlling the solid content of the impregnating agent to be 5 to 20wt%; 2S, coating the impregnating agent: placing the impregnating agent prepared in the step 1S in an oil coating box of an oil coater, coating the impregnating agent for glass fiber clusters through an oil coating roller of the oil coater to obtain theglass fiber clusters coated with the impregnating agent, wherein the rotational speed of the oil coating roller is controlled to be 8-13m / min; 3S, carrying out winding formation: winding the glass fiber clusters coated with the impregnating agent in the step 2S to be formed, and then forming molded glass fiber yarn groups, wherein the winding ratio is controlled to be 4 to 8. By adopting the preparation method of the glass fibers disclosed by the invention, glass fiber direct yarns with small degradation tension and excellent mechanical properties and suitable for a large-scale pultrusion andwinding process are prepared.

Description

technical field [0001] The invention belongs to the field of preparation of functional materials, and in particular relates to a preparation method and application of a glass fiber with low delysis tension. Background technique [0002] Since glass fiber was invented in the 1930s, it has received widespread attention and rapid development due to its excellent mechanical properties and good corrosion resistance. Especially in the past three decades, with the extensive application and research and development of polymer materials, glass fiber has become the first choice for reinforcing polymer materials, and the composite materials prepared by it have been widely used in daily life fields such as construction, automobiles, pipelines, and wind power generation. [0003] Direct yarn is a common variety in glass fiber, and its compounding with polymer materials has also developed rapidly. Many compounding technologies have emerged one after another, such as winding, pultrusion, e...
