Problems solved by technology

According to JC / T 909-2003, the thermal conductivity of inorganic fiber spraying is ≤0.045W / (m K). high
In addition, the fire performance of domestic products is also worse than that of foreign products.
Therefore, the current applications on the hull are all foreign products, and there are no domestic applications. There is an urgent need for a domestic product that can be promoted and applied.

Abstract

The invention belongs to the technical field of inorganic fiber spraying materials, and particularly relates to an aerogel inorganic fiber spraying material and a preparation method and application thereof. The aerogel inorganic fiber spraying material comprises cellucotton and glue, the weight ratio of the cellucotton to the glue is 1: (0.1-20), and the glue comprises the following components in parts by weight: 1-55 parts of water, 10-60 parts of a binder, 10-60 parts of aerogel slurry with the mass fraction of 5%-15%, 0.1-1 part of an anionic dispersant, 0.2-1 part of polyacrylamide and 0-0.1 part of sodium alginate. The material has the advantages of a common thick coating and also has the advantages of inorganic fiber spraying, and the heat conductivity coefficient and the strength of the material can be simply regulated and controlled. The material is simple in preparation method and short in construction period.

Description

technical field [0001] The invention belongs to the technical field of inorganic fiber spraying materials, and particularly relates to an aerogel inorganic fiber spraying material and a preparation method and application thereof. Background technique [0002] With the continuous development of urban modernization, various high-rise building curtain wall decoration projects have gradually increased, and the external wall thermal insulation construction technology has been continuously updated with the change of thermal insulation materials. Traditional insulation materials such as panels) have many disadvantages, such as many seams, poor sealing, complicated installation procedures, and easy to fall off and deform. It is easy to damage the integrity, stability and durability of external wall insulation, resulting in water seepage channels, which has not met the construction requirements of high efficiency, energy saving, low carbon and environmental protection. In order to s...
