Self-thermal-insulating energy-saving wall body material based on iron tailings powder and preparation method of wall body material

Abstract

The invention discloses a novel self-thermal insulating energy-saving wall body material mainly made from iron tailings powder, as well as a preparation method of the wall body material, belonging to the technical field of the novel wall body material and building energy saving. The novel iron tailings powder self-thermal-insulating energy-saving wall body material is mainly prepared from the iron tailings powder in the presence of cement serving as a gelatinization material by using a foaming technology, straw cutting, super-light weight aggregate, an interface treatment technology and various admixtures. The wall body material has the beneficial effects that the requirement of saving 65% of energy in severe cold areas is reached without being adhered with a polystyrene board outside, a wall body and the thermal insulating function are formed at one time, effect of no self ignition is achieved, A-grade fire resistance requirement is reached, the inflammable problem of the current high-molecule outer wall thermal-insulating material is solved, and the service life of the wall body material is as long as the service life of a building. A great quantity of iron tailings powder is used for saving energy and utilizing waste and the industrial policy of national building energy saving and wall body innovation is met; and compared with the similar products, the wall body material has remarkable technological and economic advantages, can be widely used in the field of buildings and can generate enormous economic and social benefits.

Description

Technical field: [0001] The invention discloses a new energy-saving wall material with self-insulation function, which uses iron tailings powder as the main raw material, and also discloses a manufacturing method of the self-insulation and energy-saving wall material, which belongs to new wall materials and building energy-saving materials Production and building energy-saving technologies. Background technique: [0002] Building energy conservation is an important part of the national energy conservation and emission reduction development strategy. About 1 billion square meters of civil buildings are put into use in my country every year, and building energy consumption accounts for about 30% of the total energy consumption. In the heat loss of the entire building, the heat loss of the heat transfer of the enclosure structure is as high as 70% to 80%. At present, the actual use of my country's construction projects is mainly the external wall insulation system, and most of ...

Problems solved by technology

In the heat loss of the entire building, the heat loss of the heat transfer of the enclosure structure is as high as 70% to 80%. At present, the actual use of my country's construction projects is mainly the external wall insulation system, and most of the materials used for external insulation are Foam plastic products, such as molded polystyrene foam (EPS) board, extruded polystyrene (XPS) board, polyurethane (PU) rigid foam, etc., but there are many problems, such as, cracking, falling off, use The service life is short, especially the fire-resistant performance is poor. The selected external insulation material is a polymer material, so it is difficult to avoid the problem of flammability. Casualties and material damage incidents occurred

It is difficult to meet the A-level fire protection requirements required by the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development
