Problems solved by technology

[0003] Among the existing inorganic thermal insulation materials, fiber thermal insulation materials such as foam glass, aluminum foam, ceramic foam, rock wool and mineral wool can meet the requirements of fire prevention performance, but considering the factors such as price, construction operability, environmental protection and energy saving, they cannot become thermal insulation materials. Mainstream products in the material market
Among them, the foamed cement insulation board has the advantages of low thermal conductivity, good heat preservation effect, non-combustible, waterproof, etc. Its disadvantages are: easy hollowing, low strength, and high water absorption rate. Although it has been develop...

Abstract

The invention provides an inorganic composite insulation board and a preparation method thereof, belonging to the technical field of novel building insulation materials. The inorganic composite insulation board is characterized by comprising the following components by weight parts: 40-48 parts of expanded perlite, 5-15 parts of phenolic foam particles, 32-36 parts of an inorganic binder, 2-6 parts of an organic reinforcing agent, 2-3 parts of a waterproof agent, 2-3 parts of inorganic enhance fibers, 1-2 parts of a hardening agent, and 1-2 parts of a fire retardant. The above raw materials are fully stirred, compressed, molded, and dried under a constant temperature to prepare the inorganic composite insulation board, and the board has advantages of good thermal insulation performance, light weight, small thermal conductivity coefficient, good stability, high intensity, convenient construction, etc., and can be widely applied in roofs and walls of various industrial and civil buildings, waterproofing and insulation of cold storages, barns and basements, as well as various cold insulation engineering.

Description

technical field [0001] The invention belongs to the technical field of new building thermal insulation materials, and in particular relates to an inorganic composite thermal insulation board and a preparation method thereof. Background technique [0002] With the advent of low-carbon economy, my country's requirements for building energy conservation are getting higher and higher. At present, there are as many as dozens of various building insulation materials, which can be described as a hundred flowers blooming. Organic insulation panels, mainly polystyrene panels (EPS), extruded panels (XPS), and polyurethane (PU), account for more than 90% of the entire insulation material market. Although the thermal insulation performance of the organic thermal insulation board is outstanding, its flame retardant and fireproof performance is slightly inferior. In recent years, fires caused by organic insulation panels in Shanghai, Beijing, Shenyang and other places have aroused wides...
