Method for preparing composite material from desulfurized gypsum
The invention relates to the technical field of building material processing, in particular to a method for preparing a composite material from desulfurized gypsum. The method mainly comprises the following steps: preprocessing waste desulfurized gypsum, preparing the preprocessed desulfurized gypsum into slurry, and carrying out surface modification; then preprocessing waste, mixing the waste with a coagulator and a composite additive, then adding surface-modified desulfurized gypsum, reacting for a period of time to prepare slurry, and finally treating the slurry to form the composite material. The waste desulfurized gypsum is combined with the waste, so that the advantages of the desulfurized gypsum and the waste are fully exerted, the production cost is reduced, and the problem of environmental pollution is effectively solved. Through surface modification and addition of various additives, the hardness, strength, impact strength, toughness, waterproof property and corrosion resistance of the composite material are improved, the comprehensive performance of the desulfurized gypsum composite material is improved, and the method has wide significance.
本发明涉及建筑材料加工技术领域，尤其涉及一种利用脱硫石膏制备复合材料的方法，该方法主要是先对废弃物脱硫石膏进行预处理，然后将预处理后的脱硫石膏制备成浆液并进行表面修饰；然后进行废料的预处理，并将废料与凝固剂、复合助剂混合，再加入表面修饰后的脱硫石膏，反应一段时间后制得浆料，最后再对浆料进行处理，以成型制得复合材料。本发明将废弃的脱硫石膏与废料结合，充分发挥了脱硫石膏与废料的优点，降低了生产的成本，有效地缓解了环境污染的问题；本发明通过表面修饰和添加各类添加剂，提高了复合材料的硬度、强度、抗冲击强度、韧性、防水性以及抗腐蚀性，提高了脱硫石膏复合材料综合的功能性，具有广泛的意义。
