Preparation method of high-strength damp-proof rock wool board
The invention belongs to the field of rock wool board materials, and particularly relates to a preparation method of a high-strength damp-proof rock wool board. The method comprises the following steps: with cotton straw as a raw material, chopping the cotton straw by using a fodder chopper and then conducting grinding and mashing by using a stone mortar to obtain pretreated cotton straw; mixing the obtained pretreated cotton straw with pectinase and deionized water and then carrying out enzymolysis; performing concentrating to obtain an enzymolysis concentrate; oxidizing the concentrate withpotassium permanganate to obtain filter residues; subjecting the filter residues, a sodium silicate solution and hydrochloric acid to mixing, heating and reacting to obtain self-made functional filler; and finally, blending the self-made functional filler and other raw materials, and conducting pressing and dehydration to obtain the high-strength damp-proof rock wool board. The rock wool board prepared through the method is good in damp-proof performance, high in mechanical strength and wide in application prospect.
本发明属于岩棉板材料领域，具体涉及一种高强度防潮岩棉板的制备方法。本发明首先以棉花秸秆为原料，用铡刀切碎后再用石臼碾压捣碎，得到预处理棉花秸秆，将得到的预处理棉花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物，再用高锰酸钾氧化酶解浓缩物后得到滤渣，将滤渣和硅酸钠溶液以及盐酸混合加热反应制得自制功能填料，最后将自制功能填料和其他原料共混后压制脱水即得高强度防潮岩棉板，本发明制备的岩棉板，防潮性能较好，机械强度较高，有广阔的应用前景。
