Abstract

The invention relates to a preparation method of an acetylene sludge foam glass thermal insulation material. The preparation method comprises the following steps of: taking industrial waste residue, namely acetylene sludge and waste glass cullet as main raw materials and sodium carbonate as a foaming agent, then mixing an appropriate amount of additives in the raw materials, carrying out ball-milling, preheating, sintering, foaming and annealing, thus obtaining the acetylene sludge foam glass thermal insulation material. The foam glass thermal insulation material prepared by the invention has the advantages of good pore structure, high mechanical strength, light weight, low water absorption, small coefficients of thermal conductivity and good thermal insulation effect. The preparation method has the advantages of realizing the resource utilization of solid wastes, improving the quality of the material while protecting the environment, saving cost and having good economic benefits.

Description

technical field [0001] The invention relates to an inorganic thermal insulation material, in particular to a calcium carbide slag foam glass thermal insulation material and a preparation method thereof. technical background [0002] With the rapid development of my country's economy, the contradiction between energy and environmental protection has become increasingly prominent. As the focus of energy-saving work, building energy conservation has been highly valued by people. Its purpose is to reduce building energy consumption and reduce environmental pollution at the same time. There are many ways to save energy in buildings, and the use of new thermal insulation materials is one of the most effective ways. [0003] Foam glass is a new type of green and environmentally friendly building material with excellent thermal insulation performance. It is based on waste glass, industrial waste or mine waste slag, mixed with appropriate foaming agent and other additives, and fire...
