Description

Acid-resistant glass fiber composition, acid-resistant glass fiber and preparation method thereof
Technical Field

At present, the glass fiber is widely applied to alkali-free glass fiber and medium-alkali glass fiber. The alkali-free glass fiber belongs to aluminoborosilicate glass fiber, has good tensile strength and electrical insulation performance, but has loose structural framework, incomplete structure and poor acid corrosion resistance because the glass components contain a certain amount of boron and fluorine, and the composite material prepared by the glass fiber is easy to be corroded by acid in an acid environment and is peeled from a resin matrix, so that the strength is rapidly lost. The medium alkali glass fiber belongs to a soda-lime silicate component, has good chemical stability, but cannot be used as an electrical insulating material due to high alkali content, and has relatively poor physical indexes such as tensile strength and the like.
