Abstract

The invention relates to a reinforced impregnating agent for alkali-free glass fibers, which is prepared by combining tetraethoxysilane, water-soluble polyester, polyurethane, 3-aminopropyltrimethoxysilane, water and paraffin emulsion in percentage by weight. The tetraethoxysilane, the water-soluble polyester and the polyurethane play a film-forming role, the 3-aminopropyltrimethoxysilane is used as a coupling agent to improve the compatibility of the mixed solution, and the paraffin serving as the emulsion has good lubricating effect. By adopting the impregnating agent of the formula, the tension of the alkali-free glass fibers can be improved, and raw material guarantee is provided for alkali-free glass fiber textile products with high strength.

Description

technical field [0001] The invention relates to a sizing agent, in particular to a reinforcing sizing agent for non-alkali glass fiber. Background technique [0002] E-glass fiber R 2 The O content is less than 0.8%, which is an aluminoborosilicate component. Its chemical stability, electrical insulation performance and strength are all very good. It is mainly used as electrical insulation material, reinforcement material of FRP and tire cord. [0003] At present, the common method of alkali-free glass fiber production is the pool kiln wire drawing method. In the production process of alkali-free glass fiber, the sizing agent plays a key role, which is used to enhance the adhesion and coating of the fiber bundle, smooth the fiber surface, increase the softness, and facilitate winding. However, the sizing agent currently used in the production process of alkali-free glass results in less strength of the fiber. Contents of the invention [0004] The purpose of the prese...
