Anti-freezing heat-preservation baking-free brick and preparation method thereof
The invention relates to an anti-freezing heat-preservation baking-free brick and a preparation method thereof, and belongs to the technical field of preparation of building materials. The preparationmethod comprises the following steps: by taking corncobs as a raw material, adding dilute sulfuric acid and a catalyst, hydrolyzing to prepare oily furfural, preparing a bacillus pasteurii liquid, pulping by using fly ash, cement, lime, gypsum and water, adding the bacillus pasteurii liquid, urea, calcium nitrate and the oily substance, carrying out injection molding and compaction molding to obtain the product, carrying out normal-temperature curing, then carrying out high-temperature and high-pressure curing, and finally removing the mold to obtain the anti-freezing heat-preservation baking-free brick. According to the invention, the high-temperature and high-pressure maintenance is carried out, and the added bacillus pasteurii liquid, urea, calcium nitrate and oily matter improve the frost resistance and thermal insulation property of the baking-free brick, so that the baking-free brick has a wide application prospect.
本发明涉及一种抗冻保温免烧砖及其制备方法，属于建筑材料制备技术领域。本发明首先以玉米芯为原料，加入稀硫酸和催化剂，水解制备油状物糠醛，接着再配制巴氏芽孢杆菌菌液，并以粉煤灰、水泥、石灰、石膏和水制浆，再加入巴氏芽孢杆菌菌液、尿素、硝酸钙和油状物后注模，振实成型，并常温养护后再进行高温高压养护，最终拆模，制得抗冻保温免烧砖；本发明进行的高温高压养护，以及加入的巴氏芽孢杆菌菌液、尿素和硝酸钙以及油状物提高了免烧砖的抗冻性和保温性能，具有广阔的应用前景。
