Abstract

The invention relates to a method for preparing color glass fibers by on-line coating, which comprises the following steps: (1) diluting glacial acetic acid, a silane coupling agent, a dye-fixing agent and water-soluble epoxy respectively with deionized water at room temperature, then orderly mixing, uniformly stirring, adding an inorganic coloring material, finally adding the balance of water to obtain an impregnating agent containing the coloring material; (2) adding the impregnating agent containing the coloring material into equipment on a glass fiber production line, preparing glass fiber protofilaments by on-line wire drawing, and finally drying to obtain the color glass fibers. The method of the invention can realize dyeing directly in the glass fiber preparation process, is simple in process, convenient for operation, energy-saving, and suitable for industrial production; the method of the invention can prepare glass fibers with various colors; dyed samples have good sunning resistance and high temperature color fastness; the color does not diffuse when the glass fiber is combined with resin to prepare composite materials; and the color is bright and not indistinct.

Description

technical field [0001] The invention belongs to the field of preparation of colored glass fibers, in particular to a method for preparing colored glass fibers by online coating. Background technique [0002] Glass fiber has a series of advantages such as easy availability of raw materials, high strength, high modulus, and corrosion resistance. It is a commonly used reinforcing material with excellent performance. In recent years, glass fiber reinforced composite materials have been developed rapidly and widely used. A large number of glass fiber reinforced plastics are used in electronic products, and people have higher and higher requirements for product appearance and vision. Therefore, the development of colored glass fibers can expand the use of glass fibers and increase their economic value. [0003] The surface of glass fiber is dense and smooth and contains less active groups, which is not conducive to the absorption and diffusion of dye molecules, which seriously af...
