Embodiment 1

[0027] ① Select an ordinary untwisted E glass fiber roving A and place it in a 400°C horse-boiling furnace for 3 hours to fully remove the surface sizing agent;

[0028] ② Prepare 1% concentration of A187 deionized water solution, soak this type of glass fiber roving A in which the sizing agent has been removed in 1% concentration of A187 solution for 1-2 minutes, take it out and dry it at room temperature for later use;

[0029] ③Modify nano-zirconia particles with A1100: Weigh 10 grams of nano-zirconia particles, ultrasonically disperse them in a three-necked flask with 500 ml of deionized water / ethanol solvent (volume ratio 1:1), stir until evenly mixed, and drop 5 g of A1100 coupling agent, keep the temperature at 80°C for reflux reaction for 12 hours after the dropwise addition, use a high-speed centrifuge to separate the nano-zirconia particles modified by the coupling agent from the solvent, and then disperse these particles in deionized water Dipping the roving treated...

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 ...
