Lightweight and high-strength thermal insulation material and preparation method thereof

Abstract

The invention discloses a light high-strength heat preservation material .The light high-strength heat preservation material is prepared from, by weight, 100 parts of cement, 10-20 parts of vermiculite, 25-50 parts of coal ash, 25-50 parts of pelletized ferrochromium slag, 0.25-1.5 parts of activator, 10-22 parts of additive and 110-180 parts of water .The invention further provides a preparation method of the heat preservation material .According to the heat preservation material, a large amount of pelletized ferrochromium slag is utilized, the production cost can be reduced, the ecological environment can be improved, waste is turned into wealth, and remarkable economic benefits and social benefits are achieved .The activator has a very good activating function on the pelletized ferrochromium slag, and the prepared heat preservation material has the advantages of being light, high in strength and good in heat preservation and insulation performance, is a currently ideal novel building heat preservation material, can be directly used as a heat preservation material, can also be used as a structural filling core material, and is very wide in application prospect.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a light-weight, high-strength thermal insulation material and a preparation method thereof. Background technique [0002] Thermal insulation is an important performance of building walls. In the cold northern regions, the requirements for this index are more stringent. From the perspective of social energy consumption structure, the world's building energy consumption has reached about 1 / 3 of the total energy consumption; it will gradually increase with the improvement of people's living standards. With the continuous deepening of wall material innovation and building energy-saving work in our country, the requirements of new building energy-saving design standards have also been increased. In order to improve the thermal insulation function of buildings, more and more building thermal insulation blocks have appeared in China today. product. Most of the products on the market st...

Problems solved by technology

[0003] Ferrochrome slag is chromium-containing waste slag produced during pyrochrome smelting of ferrochromium alloys. At present, the utilization rate of ferrochrome slag is low, resulting in a large amount of accumulation in the slag yard, which not only encroached on a large number of fertile fields, but also polluted groundwater and soil, endangering people and livestock in runoff areas. Safety, but also caused a lot of waste of waste resources
