Abstract

The invention belongs to the technical field of novel wall materials and relates to a lightweight heat-preserving plate produced by using red mud as a main raw material. The red mud foaming lightweight heat-preserving plate is prepared from the following raw materials in part by weight: 100 parts of red mud, 2 to 5 parts of sulfate exciting agent, 1.0 to 1.4 parts of sulphate aluminium cement, 0.2 to 1.4 parts of polycarboxylic acid water reducing agent, foam and 21 to 28 parts of water, wherein the volume (liter) of the foam is 60 to 100 percent of the weight (kilogram) of the red mud. The red mud foaming lightweight heat-preserving plate comprises a large number of sealed holes, has light weight and small heat conductivity coefficient, is applicable to heat preservation and heat insulation of building walls, and is a lightweight heat-preserving material with a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to a light-weight thermal insulation board produced from red mud as a main raw material. Background technique [0002] Building energy conservation and comprehensive utilization of industrial waste have become the basic national policy of our country. Using industrial waste to develop new building materials that meet the national building energy conservation standards has become the mission of material researchers. [0003] The implementation of building energy-saving policies has promoted the development of wall thermal insulation materials. Organic thermal insulation materials such as foam plastics are widely used in wall materials. However, organic thermal insulation materials have poor fire resistance, aging resistance, and large deformation coefficients, which restrict their rapid development as thermal insulation materials. Compared with organic thermal insulation ma...
