Solid waste-based sulfur-aluminum cementing material/phenolic resin composite material and preparation method thereof
The present invention discloses a solid waste-based sulfur-aluminum cementing material/phenolic resin composite material and a preparation method thereof. The preparation method comprises the following steps: mixing the solid waste-based sulfur-aluminum cementing material with an absolute ethyl alcohol solution of phenolic resin, adding a plasticizer in the mixing process to obtain a mixture, carrying out hot press molding on the mixture to obtain a primary product material, and carrying out high-temperature curing on the primary product material to obtain the solid waste-based sulfur-aluminum cementing material/phenolic resin composite material. The hot press molding temperature is 140-200 DEG C, the high-temperature curing temperature is 140-200 DEG C, and the solid waste-based sulfur-aluminum cementing material is prepared by calcining desulfurized gypsum, aluminum ash, carbide slag and coal gangue. The composite material provided by the invention is compact in structure, low in porosity, small in aperture, excellent in mechanical property, particularly excellent in compressive strength, and relatively good in low-temperature property, and can be applied at a low temperature.
本发明公开了固废基硫铝系胶凝材料/酚醛树脂复合材料及制备方法，将固废基硫铝系胶凝材料与酚醛树脂的无水乙醇溶液进行混合，混合过程中添加增塑剂获得混合料，将混合料热压成型获得初品材料，将初品材料进行高温固化即得；其中，热压成型的温度为140～200℃，高温固化的温度为140～200℃，所述固废基硫铝系胶凝材料为脱硫石膏、铝灰、电石渣、煤矸石经煅烧制备获得。本发明提供的复合材料结构致密、孔隙率低且孔径小，具有优良的力学性能，尤其抗压强度优异，同时具有较好的低温性能，可以在低温下应用。
