Problems solved by technology

[0003] At present, most of the wall insulation materials used are foam boards made of polymer materials. Although these materials can meet the requirements of building energy conservation, they are generally flammable and have certain pollution to the environment during the production process. , therefore, this type of material has been classified as a strictly restricted use material

Description

technical field [0001] The invention relates to building wall materials, in particular to a non-asbestos fiber oil-resistant and high-temperature-resistant calcium silicate board. Background technique [0002] In recent years, with the rapid development of the real estate industry, people pay more and more attention to the construction industry closely related to it. Therefore, people's requirements for wall materials, which are an important part of building materials, are also getting higher and higher. And because in recent years, people pay more and more attention to environmental protection and energy saving, so integrating the concepts of environmental protection and energy saving into wall materials is the development trend of wall materials in the future. [0003] At present, most of the wall insulation materials used are foam boards made of polymer materials. Although these materials can meet the requirements of building energy conservation, they are generally flamma...
