Problems solved by technology

Once the material degrades, the performance will change and the insulation effect cannot be guaranteed
The third is the cost of organic insulation materials
However, its thermal insulation performance is not very good, and it cannot be directly used as building exterior wall bricks. Therefore, it is very realistic to study and explore building insulation exterior wall bricks that are light, high-strength, safe, cheap, simple in construction, and meet national requirements. significance

Abstract

The invention discloses a coal gangue building thermal insulation exterior wall brick, which is prepared by the following raw materials, by weight, 50-70% of coal gangue, 3-12% of a plasticizing agent, 3-12% of a binder, 10-30% of a vitrifying agent, 2-5% of a foaming agent, and 0.1-0.3% of a pore adjusting agent. In addition, the present invention further provides a production method for the coal gangue building thermal insulation exterior wall brick. The thermal insulation exterior wall brick of the present invention has advantages of light weight, high strength, safety, aging resistance, low cost and the like, can be directly used for beautifying modification of the building, and has a certain bearing capacity. With the present invention, the harm to the environmental and the safety due to the coal gangue is eliminated, and the performances of the building thermal insulation material in our country can be improved. Compared to the organic thermal insulation material, the thermal insulation exterior wall brick of the present invention has advantages of good safety performance, low cost, simple construction, and good durability, and the industrial waste residue is utilized by thethermal insulation exterior wall brick of the present invention so as to reduce the land occupation and the environment pollution.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a coal gangue building thermal insulation exterior wall brick and a production method thereof. Background technique [0002] At present, our country's dependence on overseas energy is more than 50%, and the tense situation of energy is already very serious in our country. In such a tight resource situation, the energy consumption of residential buildings accounts for 32% of the national energy consumption. On November 1, 1997, the state promulgated the original "Energy Conservation Law". It is stipulated that the design and construction of buildings shall be in accordance with relevant laws and administrative regulations, adopt energy-saving building structures, materials, appliances and products, improve thermal insulation performance, and reduce energy consumption for heating, cooling and lighting. [0003] At present, my country's building insulation m...
