Preparation method for alkali-resistant fiberglass

Abstract

The invention discloses a preparation method for alkali-resistant fiberglass. The preparation method comprises the following steps: (1) removing an impregnating compound from the surface of E fiberglass in a roasting way; (2) performing surface treatment on the E fiberglass treated in the step (1) by using a silane coupling agent A187; (3) performing surface modification on zirconium oxide nanoparticles by using a silane coupling agent A1100; (4) attaching the zirconium oxide nanoparticles treated in the step (3) to the surface of the E fiberglass treated in the step (2), and performing reaction at 80-130 DEG C for 1-4 hours to obtain the alkali-resistant fiberglass. According to the method, the alkali resistance of the E fiberglass can be improved by chemically modifying the surface of the fiberglass on the basis of preserving the original high physical properties of the E fiberglass.

Description

technical field [0001] The invention relates to a preparation method of alkali-resistant glass fiber. Background technique [0002] Alkali-free glass fiber (E-glass fiber) is a very good lightweight, high-strength, multi-functional reinforcement material. The characteristic of alkali-free glass fiber is that its alkaline metal oxide content is less than 1%. Compared with medium-alkali or alkali-resistant glass fiber, its physical properties are excellent but its alkali resistance is poor. The application in alkali-resistant fields such as packaging materials has great limitations. In recent years, a lot of work has been done on the research of alkali-resistant glass fibers at home and abroad, but their research results are mainly based on the adjustment of the metal oxide components in the glass formula, that is, by adjusting the ZrO 2 and TiO 2 The content in the glass formula can achieve the purpose of improving the alkali resistance of the glass fiber, but this method ...

In recent years, a lot of work has been done on the research of alkali-resistant glass fibers at home and abroad, but their research results are mainly based on the adjustment of the metal oxide components in the glass formula, that is, by adjusting the ZrO 2 and TiO 2 The content in the glass formula can achieve the purpose of improving the alkali resistance of the glass fiber, but this method is costly, and at the same time, the change of the glass formula will also affect the entire drawing process of the glass fiber, resulting in fluctuations in product performance, and when adjusting the glass After the metal oxide component in the fiber content, the mechanical properties and other physical properties of the glass fiber will be greatly affected, so a new method for the preparation of alkali-resistant glass fiber is found, while retaining the excellent physical properties of the original E glass fiber It is particularly important to improve the alkali resistance of E glass fiber on the basis of E glass fiber, but so far there is no report on the invention content of this type of alkali resistant glass fiber
