Dry-mixed mortar and preparation method thereof
The invention relates to the field of building materials, and particularly discloses dry-mixed mortar. The dry-mixed mortar is prepared from the following raw materials: cement, sand, fly ash, thickening powder, modified waste rubber particles and silicon dioxide aerogel; the modified waste rubber particles are obtained by performing surface oxidation modification on waste rubber particles through strong oxidizing acid, and the waste rubber particles are obtained by crushing waste tires; the preparation method comprises the following steps: mixing the modified waste rubber particles with the silicon dioxide aerogel, and continuously stirring to obtain a first mixture; mixing the rest raw materials, and continuously stirring to obtain a second mixture; and adding the first mixture into the second mixture while stirring, and continuously stirring to obtain the dry-mixed mortar. The dry-mixed mortar has the advantage of improving the thermal insulation performance of the dry-mixed mortar.
本申请涉及建筑材料领域，具体公开了一种干混砂浆。干混砂浆由包括以下原料制备得到：水泥，砂，粉煤灰，稠化粉，改性废旧橡胶颗粒，二氧化硅气凝胶；改性废旧橡胶颗粒由废旧橡胶颗粒经强氧化性酸表面氧化改性得到，废旧橡胶颗粒由废旧轮胎破碎得到；其制备方法为：将改性废旧橡胶颗粒与二氧化硅气凝胶混合并持续搅拌得到第一混合物；将剩余原料混合，持续搅拌得到第二混合物；边搅拌边向第二混合物中加入第一混合物，持续搅拌得到干混砂浆。本申请的一种干混砂浆具有提高干混砂浆保温性能的优点。
