High-performance polyvinyl alcohol layered fiber cement board and preparation method thereof
The invention discloses a high-performance polyvinyl alcohol layered fiber cement board and a preparation method thereof, the polyvinyl alcohol layered fiber cement board comprises a lower layer, a middle layer and an upper layer, the lower layer is a PVA fiber concrete layer, the middle layer is a low-density heat insulation concrete layer, and the upper layer is a waterproof concrete thin layer. Compared with a traditional fiber cement board, the polyvinyl alcohol layered fiber cement board has the layering and lower layer tensile stress effects conforming to the mechanical principle, the PVA fiber concrete face board with excellent tensile and deformation performance is used, the light low-density heat insulation concrete face board is adopted when the middle layer is pressed, and the mechanical property targets of light weight and high strength are achieved; and the use of fibers and high-grade cement is reduced, so that the material cost of the product is reduced. The whole product has the functions of heat preservation, heat insulation, water resistance, sound insulation and the like, so that the comprehensive performance of the cement board is improved.
本发明公开了一种高性能聚乙烯醇分层纤维水泥板及其制备方法，所述聚乙烯醇分层纤维水泥板包括下层、中层、上层结构，其中下层为PVA纤维混凝土层，中层为低密隔热混凝土层，上层为防水混凝土薄层。本发明聚乙烯醇分层纤维水泥板相较于传统的纤维水泥板，具有符合力学原理的分层，下层受拉应力作用，使用具有优异抗拉和变形性能的PVA纤维混凝土面板，中层受压则采用轻质的低密隔热混凝土面板，实现了轻质高强的力学性能目标，并减少了纤维和高标号水泥的使用，从而降低了产品的材料成本。整个产品兼具了保温隔热、防水、隔音等功能，进而提升了水泥板的综合性能。
