Thermal insulation and heat preservation slurry composition and thermal insulation and heat preservation plate containing the same

Abstract

The invention provides a thermal insulation and heat preservation slurry composition, which comprises the following components, by weight, 20-60 parts of an inorganic powder binder, 15-40 parts of a lightweight aggregate, 10-25 parts of a magnesium-containing mineral, 10-15 parts of reinforcing fibers, and a proper amount of water. The present invention further provides a thermal insulation and heat preservation plate containing the thermal insulation and heat preservation slurry composition, wherein the thermal insulation and heat preservation plate comprises one or more than two thermal insulation and heat preservation material layers, and thermal insulation and heat preservation slurry layers covered on both surfaces of the thermal insulation and heat preservation material layer. The thermal insulation and heat preservation plate has the following characteristics that: a thermal insulation and heat preservation performance is excellent; non-combustible property is provided, or combustion is not generated when the plate contacts open fire; the plate is mainly prepared from inorganic materials, such that characteristics of no toxic or harmful gas release and the like during use are provided; and the plate can be widely used in cold northern regions, and is the best alternative of polyphenylene plates, polyurethane plates and other materials.

Description

【Technical field】 [0001] The invention relates to the field of building materials, in particular to a thermal insulation slurry composition and a thermal insulation board containing the composition. 【Background technique】 [0002] The essence of building energy conservation is to scientifically and rationally improve the thermal performance of the outer envelope according to the characteristics of different climate zones. my country has a vast territory and different climates, and the key points and countermeasures for energy conservation are also fundamentally different. Taking the two basic climate zones of hot summer and cold winter and cold in China as examples, the building energy-saving technologies and requirements of each region are different. [0003] For regions with hot summer and cold winter, the area is hot in summer and cold in winter. It is necessary to ensure that the outer envelope has good thermal insulation performance and meet the requirements for heat di...

AI Technical Summary

Problems solved by technology

At present, most of the buildings in this area adopt the structure of external thermal insulation. The thermal insulation materials mainly include the following types: polystyrene, extruded polystyrene, polyurethane, glass wool, rock wool, phenolic glass wool and inorganic thermal insulation mortar. Due to the above-mentioned types of external thermal insulation The fire-resistant grades of materials are different. Therefore, before the introduction of new external insulation materials for building exterior walls, according to relevant industry management regulations, only glass wool, rock wool, and phenolic glass wool can meet the requirements for the A-level fire resistance grade of building external insulation materials. Because of these The external thermal insulation materials that meet the requirements still have various defects such as high water absorption rate, unstable shape, easy chalking, and poor connection with the facing layer. Therefore, the external thermal insulation of buildings in this area has an embarrassing situation of front and rear disconnection. , at present, the manufacturers of these materials are seeking technological breakthroughs to solve the problem of popularization and application
