Problems solved by technology

[0003] Among inorganic insulation boards, foam glass boards and foam ceramic boards consume a lot of energy in the early stage of production and the price of finished products is high; expanded perlite boards and expanded vermiculite boards have defects such as high water absorption and poor frost resistance; rock wool boards, Mineral wool boards, glass wool boards and other fiber boards are seriously polluted during the production and construction process, causing great harm to the human body
[0004] The quality of traditional cement foam boards in the market is mixed. Because of the influence of raw materials, formula ratio, production process, production equipment, production environment and many other conditions, there are many shortcomings: poor board strength, easy to collapse, low closed cell rate, frost resistance Poor performance, large drying shrinkage, easy cracking and other defects, the product quality cannot meet the requirements of construction acceptance, so it has not been well popularized and developed in my country's construction applications

Description

technical field [0001] The invention relates to the field of building energy-saving materials and construction technology, in particular to a preparation method of an inorganic foamed fireproof and thermal insulation board. Background technique [0002] In recent years, fires caused by thermal insulation materials have occurred frequently in our country, and the frequency and the huge loss of personnel and property are shocking. At present, the insulation materials used in the market mainly include organic foaming materials such as molded polystyrene board, extruded polystyrene board, and polyurethane foam. The biggest problem with these insulation materials is their poor fireproof performance. Even the sparks generated by electric welding can make these insulation materials catch fire and produce a large amount of toxic and harmful smoke. From this point of view, it has become a general trend to replace organic foam materials with inorganic non-combustible thermal insulati...
