Flame-retardant thermal insulation wall material mixed with alumina tailings and preparation method thereof

Abstract

The invention discloses a flame-retardant thermal insulation wall material mixed with alumina tailings and a preparation method thereof. The flame-retardant thermal insulation wall material mixed with alumina tailings is prepared according to the following ratio of raw materials by weight: cement 25-55 16-45 parts of alumina tailings, 12-28 parts of cinder, 14-32 parts of yellow sand, 6-16 parts of superplasticizer, 25-55 parts of water, 12-35 parts of ammonium polyphosphate, 8- 25 parts, 5-28 parts of flame retardant, 2-14 parts of reinforcing agent, 2-14 parts of waterproofing agent, 2-14 parts of retention aid. The preparation method is to pulverize the above solid raw materials and stir evenly, then add water, high-efficiency water reducer, ammonium polyphosphate, flame retardant, reinforcing agent, water repellent, retention aid, foam and stir to prepare a mixture, and the mixture is extruded Forming, calcining, and cooling out of the kiln can obtain the flame-retardant thermal insulation wall material mixed with alumina tailings.

Description

technical field [0001] The invention relates to wall materials, in particular to a flame-retardant thermal insulation wall material mixed with alumina tailings and a preparation method thereof. Background technique [0002] With the rapid development of society, people's demand for energy is increasing day by day, and the long-term excessive consumption of energy has led to the extreme shortage of energy. High energy consumption has always been an urgent problem for researchers to solve, and building energy consumption accounts for a very large proportion of all energy consumption. The high thermal conductivity of traditional thermal insulation materials can no longer meet people's needs to solve energy problems. To develop a low-cost , ultra-efficient, and flame-retardant wall insulation materials have become the focus of current research. [0003] According to literature reports, the tailings produced by the mining and utilization of mineral resources have seriously pollu...

Problems solved by technology

At present, there are also wall materials prepared by using iron tailings, alumina tailings, etc., but the components of the wall materials and the addition ratio of the components are not designed reasonably, and the activity of the tailings cannot be effectively stimulated. In order to consider the flame retardancy of the product, the preparation process is complicated and the utilization rate of tailings is not high. The prepared wall material has poor flame retardancy and low strength, which cannot meet the current requirements of light weight, flame retardancy and heat preservation of buildings.
