The invention belongs to the field of brick making, and particularly relates to a preparation method of a baking-free brick. The preparation method comprises the following steps of: firstly, taking corn straws as raw materials, chopping the corn straws by using a chopper, and then rolling the chopped corn straws by using a stone roller to obtain pretreated corn straws; mixing the obtained pretreated corn straws with pectinase and deionized water, then carrying out enzymolysis, and concentrating to obtain an enzymolysis concentrated solution; then mixing the enzymolysis concentrated solution with raw materials such as coal ash, cement and lime to prepare slurry, and carrying out high-temperature and high-pressure reaction on the obtained slurry; and finally, carrying out injection molding on the slurry subjected to the high-temperature and high-pressure reaction, and carrying out steam curing to finally obtain the baking-free brick. The baking-free brick prepared by the preparation method is relatively low in water absorption rate, relatively high in compactness and relatively high in mechanical strength, and has a wide application prospect.
本发明属于制砖领域，具体涉及一种免烧砖的制备方法。本发明首先以玉米秸秆为原料，用铡刀切碎后再用石磙碾压，得到预处理玉米秸秆，将得到的预处理玉米秸秆和果胶酶以及去离子水混合后酶解，并浓缩得到酶解浓缩液，随后将酶解浓缩液和粉煤灰、水泥、石灰等原料混合制浆，将得到的浆料并高温高压反应，最后将高温高压反应后的浆料注模并蒸汽养护，最终得到免烧砖，本发明制备的免烧砖，吸水率较低、密实度较高，机械强度较强，有广阔的应用前景。
