High-performance glass fiber wetting agent and preparation method thereof

Abstract

The invention discloses a high-performance glass fiber wetting agent and a preparation method thereof. The high-performance glass fiber wetting agent is prepared from the following raw materials in parts by weight: 45-55 parts of epoxy resin, 30-40 parts of polyoxyethylene glycol, 5-10 parts of trimethylolethane, 10-20 parts of an acrylate emulsion, 5-7 parts of potato starch, 5-7 parts of corn starch, 4-6 parts of cotmar, 0.1-1.2 parts of a softening agent, 7-9 parts of grease paraffin, 3-5 parts of a coupling agent, 0.5-1 part of a lubricating agent, 0.5-1 part of a preservative, 0.1-0.5 part of an organic tin bactericide, 0.3-0.5 part of a de-foaming agent and 60-80 parts of water. According to the invention, the physical and chemical properties of an electronic spinning yarn of glass fiber are comprehensively improved, the stiffness is within 50-80, the tensile strength reaches up to 52CN / TEX or above and the problems of yarn break and fluffing in the spinning process can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of glass surface coating, in particular to a high-performance glass fiber sizing agent and a preparation method thereof. Background technique [0002] During the drawing production process of glass fiber electronic textile yarn, it is necessary to coat the surface of glass fiber monofilament with sizing agent to play the role of bonding, lubricating and protecting glass fiber, and at the same time improve the physical and chemical properties of glass fiber to make glass fiber electronic textile Yarn properties can be adapted to the needs of the textile process. [0003] At present, the general-purpose glass fiber electronic textile yarn sizing agent is not enough to improve the physical and chemical properties of glass fiber, and cannot protect the stress condition of glass fiber in the weaving process, resulting in the glass fiber electronic textile yarn under various tensions and frictions. Under such con...

Problems solved by technology

[0003] At present, the general-purpose glass fiber electronic textile yarn sizing agent is not enough to improve the physical and chemical properties of glass fiber, and cannot protect the stress condition of glass fiber in the weaving process, resulting in the glass fiber electronic textile yarn under various tensions and frictions. Under these conditions, single fiber breakage or even the whole bundle of yarn breakage often occurs, which seriously affects the smooth progress of the textile process, and brings serious defects to textile products, greatly reducing the quality level of textile products
