Modified carbon fiber reinforced inorganic composite material and preparation method thereof
The invention provides a modified carbon fiber reinforced inorganic composite material and a preparation method thereof. The preparation method comprises the following steps: providing cement-based slurry; providing a carbon fiber bundle with a sizing agent on the surface, placing the cement-based slurry in a slurry tank, and enabling the carbon fiber bundle to alternately pass through rollers in the slurry tank up and down to obtain a carbon fiber bundle impregnated with the cement-based slurry; a conical nozzle is arranged at the outlet end of the slurry tank; enabling the carbon fiber bundles impregnated with the cement-based slurry to pass through a conical nozzle to form rod-shaped carbon fibers; and vertically hanging the rod-shaped carbon fibers in air for air drying, after the rod-shaped carbon fibers are hardened into carbon fiber rods, covering the carbon fiber rods with a film for constant-temperature maintenance, and then putting the carbon fiber rods into a sealing bag for constant-temperature maintenance to obtain the modified carbon fiber reinforced inorganic composite material. The method can effectively improve the combination degree of the carbon fibers and the cement dipping matrix, and improves the dipping effect of the cement coating.
本发明提供一种改性碳纤维增强无机复合材料及其制备方法，制备方法包括：提供水泥基浆液；提供表面具有上浆剂的碳纤维束，将水泥基浆液盛放于浆液槽中，将碳纤维束上下交替地穿过浆液槽中的辊，得到浸渍水泥基浆液的碳纤维束；浆液槽出口端设有锥形喷嘴；将浸渍水泥基浆液的碳纤维束穿过锥形喷嘴，形成棒状碳纤维；将棒状碳纤维垂直悬挂在空气中风干，待其变硬成为碳纤维棒后，覆盖薄膜恒温养护，再放入密封袋中恒温养护，得到改性碳纤维增强无机复合材料。本发明能够有效提高碳纤维与水泥浸渍基质的结合程度，提升水泥涂层的浸渍效果。
