Abstract

The invention provides a preparation method of an inorganic polymer material based on industrial solid waste recycling, which comprises the following steps: step S01, putting industrial solid waste, active silicon oxide, active aluminum oxide powder, a corundum composite additive and a water reducing agent into a stirrer, uniformly mixing to form a dry mixed material, s02, adding a liquid exciting agent into the uniformly stirred dry mixing material, and uniformly mixing again to obtain a wet mixing material, and S03, molding: putting the wet mixing material into a mold, and standing by in a vibration and vacuumizing mode; s04, the formed material is subjected to standing; and step S05, drying to obtain the inorganic polymer material. According to the method provided by the invention, the cost caused by purification, enrichment and the like in the current industrial solid waste recycling process is effectively reduced.

Description

technical field [0001] The invention belongs to the field of inorganic polymer materials, and relates to a preparation method of inorganic polymer materials, in particular to a preparation method of inorganic polymer materials based on industrial solid waste recycling. Background technique [0002] Solid waste has the characteristics of scattered sources, large output, complex composition, and sluggishness. Some of them also have dangerous characteristics such as toxicity, flammability, explosion, radioactivity, and corrosion. In the process, it will cause harm to the water body, the atmosphere, and the soil system, destroy the ecological environment, and even hinder the physical and mental health of human beings and the development of the country's social economy. [0003] The utilization of industrial solid waste as a resource is one of the important ways to achieve the healthy development of China's economy. At present, the resource utilization of industrial solid waste ...
