Glass fiber modified composite material, preparation method and application
The invention discloses a glass fiber modified composite material, a preparation method and application, and the preparation method of the glass fiber modified composite material comprises the following steps: dissolving a surfactant in deionized water, then adding glass fiber for reaction, cooling to room temperature after the reaction, and filtering to obtain the glass fiber modified composite material. Wherein the surfactant can generate ion induction and interface fusion effects with the glass fibers; the preparation method of the surfactant comprises the following steps: dissolving polyvinyl alcohol in deionized water, then sequentially adding sodium chloride and n-butyraldehyde, adjusting the pH value for reaction, and after the reaction, filtering, washing and drying to obtain the surfactant. The surfactant prepared by taking sodium chloride as a raw material can generate ion induction and interface fusion effects with the glass fibers, so that the prepared glass fiber modified composite material has good dispersity in cement, and the breaking strength of the cement can be remarkably improved.
本发明公开了玻璃纤维改性复合材料、制备方法及应用，玻璃纤维改性复合材料制备的方法步骤如下：将表面活性剂溶于去离子水中，然后加入玻璃纤维进行反应，反应后降至室温，过滤后即得玻璃纤维改性复合材料；其中表面活性剂可与玻璃纤维发生离子诱导和界面融合效应；表面活性剂的制备方法步骤如下：将聚乙烯醇溶解在去离子水中，然后再依次加入氯化钠和正丁醛，调节pH进行反应，反应后经过滤、洗涤和烘干即得表面活性剂。本发明以氯化钠为原料制备的表面活性剂能够与玻璃纤维发生离子诱导和界面融合效应，使得制备的玻璃纤维改性复合材料在水泥中的分散性好，能够显著提高水泥的抗折强度。
