Problems solved by technology

This kind of fireproof board is applied to xonotlite. The quality problems that are prone to occur in xonotlite insulation products are mainly high damage rate and low recovery rate. The maximum heat-resistant temperature of some products does not meet the requirements, and cracks and shrinkage are prone to occur when heated. etc.; In addition, one of the biggest disadvantages of xonotlite is its high water absorption rate and it is not waterproof
[0008] At present, although the fireproof performance of inorganic thermal insulation materials can be guaranteed, their high density, low mechanical strength, and high water absorption rate cannot meet the construction requirements of thin plaster external thermal insulation, and their application fields are limited.

Description

technical field [0001] The invention relates to a fireproof heat preservation board, in particular to an inorganic fireproof heat preservation board and its manufacturing method and application, belonging to the technical field of construction engineering. Background technique [0002] With the intensification of the world's energy crisis and the further deterioration of the ecological environment, the contradiction between my country's energy and environmental protection issues has become more prominent due to the continued rapid economic development. The impact of building insulation and energy conservation on the ecological environment has attracted the attention of the industry, requiring building exterior walls to be done For the insulation layer, the amount of insulation materials used will be surprisingly large, which will not only consume a lot of resources, but may also cause new environmental problems. Therefore, thermal insulation and energy saving work must be ori...
