Aerated building block composite material and preparation method thereof
The invention discloses an aerated building block composite material and a preparation method thereof, and belongs to the technical field of building materials, the aerated building block composite material comprises the following components by weight: 80-90 parts of Portland cement, 20-30 parts of quartz sand, 13-15 parts of modified cellulose, 12-13 parts of modified rubber powder, 6-8 parts of a water repellent, 3-5 parts of an antifoaming agent and 1-3 parts of a water reducer. The preparation method of the modified cellulose comprises the step of taking lignocellulose extracted from pulping and papermaking black liquor powder as a raw material. According to the invention, the modified rubber powder is doped, so that the cohesion of the aerated building block composite material can be improved, the tensile bonding strength of particle bonds of the aerated building block composite material can be enhanced, and meanwhile, certain bubbles can be introduced, so that the compression-bending ratio of the aerated building block composite material is effectively weakened, and the toughness of the aerated building block composite material is improved; due to the doping of the modified cellulose, the compressive strength and the breaking strength of the aerated building block composite material are effectively compensated, and the modified cellulose has relatively high thermal stability and viscosity.
本发明公开了一种加气砌块复合材料及其制备方法，属于建筑材料技术领域，所述加气砌块复合材料由以下重量份数的组份：硅酸盐水泥80‑90份、石英砂20‑30份、改性纤维素13‑15份、改性胶粉12‑13份、憎水剂6‑8份、消泡剂3‑5份和减水剂1‑3份，所述改性纤维素的制备方法包括：以制浆造纸黑液粉末中提取的木质纤维素为原料。本发明中，改性胶粉的掺入，能够提升加气砌块复合材料的内聚力，增强加气砌块复合材料粒子键的拉伸黏结强度，同时还能够引入一定的气泡，有效削弱了加气砌块复合材料的压折比，从而提高了加气砌块复合材料的韧性，改性纤维素的掺入，有效弥补了加气砌块复合材料的抗压抗折强度，改性后的改性纤维素具有较高的热稳定性和黏度。
