The invention discloses a light coal gangue brick and a preparation method thereof, and belongs to the technical field of building materials. The light coal gangue brick comprises the following raw materials by weight: 10-15 parts of modified nanoparticles, 75-85 parts of coal gangue, 5-10 parts of clay, 20-25 parts of fly ash, 5-6.5 parts of a reinforcing agent, 3-5 parts of blast furnace slag, and 2.5-5.5 parts of bentonite. Polylactic acid and an intermediate 2 are mixed and react in a solvent 1, 4-dioxane. The intermediate 2 serves as a modifier and amino groups thereon can attack ester bonds in the polylactic acid to form amido bonds, hydrophilic ether bonds are introduced, and the hydrophilic performance of the polylactic acid is improved. The intermediate 2 is introduced as a side chain, a sample is formed through hot pressing, and the modified nanoparticles are prepared. The modified polylactic acid nanoparticles are heated and decomposed to form pores in the brick, but the raw materials dispersed in the brick are sintered into a brick body, so that the weight of the brick is reduced without influencing the mechanical strength of the coal gangue brick, and the usability of the coal gangue brick is improved.
本发明公开一种轻质煤矸石砖及其制备方法，属于建筑材料技术领域，包括如下重量份原料:10‑15份改性纳米微球，75‑85份煤矸石，5‑10份黏土，20‑25份粉煤灰，5‑6.5份增强剂，3‑5份高炉渣，2.5‑5.5份膨润土；将聚乳酸和中间体2在溶剂1,4‑二氧六环中混合反应，中间体2作为改性剂，其上的氨基能够进攻聚乳酸中的酯键形成酰胺键，并且引入亲水的醚键，增加聚乳酸的亲水性能，而且通过引入中间体2作为侧链，热压成样品，制备出改性纳米微球，改性聚乳酸纳米粒子受热分解，在砖内形成孔隙，但是分散在内部的原料烧结成砖体，在不影响煤矸石砖力学强度的前提下减轻其重量，提高煤矸石砖的使用性能。
