Belonging to the technical field of autoclaved coal gangue bricks, the invention relates to a high strength autoclaved coal gangue brick based on industrial waste residue, which comprises the following raw materials: coal gangue, Portland cement, calcium oxide, diatomite, calcium sulfate, modified polypropylene fiber, sodium sulfate, rosin thermopolymer and water. Wherein the modified polypropylene fibers are polypropylene fibers grafted with phase-change capsule-shaped particles, and have the following effects: firstly, the grafted phase-change capsule-shaped particles not only improve the roughness of the surfaces of the polypropylene fibers and increase functional groups on the surfaces of the polypropylene fibers, so that the modified polypropylene fibers are more uniformly dispersed in a stone brick base material; the binding property of the modified polypropylene fiber and the stone brick base material is stronger, and the improvement of the breaking strength and the crack resistance of the coal gangue brick by the modified polypropylene fiber is promoted; and secondly, the phase-change capsular particles are good thermal insulation materials, so that the modified polypropylene fiber not only has an anti-cracking enhancing effect, but also has a thermal insulation enhancing effect.
本发明涉及一种基于工业废渣的高强度蒸压煤矸石砖，属于蒸压煤矸石砖技术领域，包括以下原料：煤矸石、硅酸盐水泥、氧化钙、硅藻土、硫酸钙、改性聚丙烯纤维、硫酸钠、松香热聚物和水。其中，改性聚丙纤维为接枝有相变囊状颗粒的聚丙纤维，具有以下作用：一是，接枝的相变囊状颗粒不但提高了聚丙烯纤维表面的粗糙程度，增加其表面的官能团，使得改性聚丙烯纤维在石砖基料中分散得更加均匀，使得改性聚丙烯纤维与石砖基料的结合性更强，促进改性聚丙烯纤维对煤矸石砖的抗折强度的增强，以及抗裂增强；二是，相变囊状颗粒为良好的保温材料，使得改性聚丙烯纤维不但具有抗裂增强作用，还具有保温增强作用。
