利用陶瓷抛光废料制备高强轻质建筑材料的研究

Study on Preparation of High-strength-lightweight Building Materials with Porcelain Polishing Waste

本研究以陶瓷抛光废料为主要原料,辅以长石、球土、石英等,通过大量的探索性实验,确定了制备轻质建筑材料的基础配方。在此基础上,通过正交实验优化原料配方和工艺参数制备了高强轻质建筑材料。在球磨时间42min、烧成温度1170℃、保温时间15 min、添加剂含量5.5wt%时,制备出体积密度0.81 g/cm3、抗压强度14.25MPa、吸水率9.30%、导热系数0.30 W/m.K的高强轻质建筑材料。

A fundamental formulation for preparing lightweight building material was ascertained through a lot of exploring experiments with porcelain polishing waste as main raw material and feldspar, ball clay and quartz etc. as minor raw materials. On this basis, high-strength-lightweight building materials were prepared by optimizing the formulation of raw materials and processing parameters with the orthogonal experiments. At the conditions of ball milling time 42 min, sintering temperature 1170 ℃, holding time 15 min, and the additive content 5.5wt%, the high-strength-lightweight building material reachs the sintered bulk density 0.81 g/cm3, compressive strength 14.25 MPa, water absorbing capacity 9.30% and thermal conductivity coefficient 0.30 W/m ·K.
