Abstract

The invention discloses an inorganic nonmetallic light fireproof thermal insulation board, which comprises raw material components in percentage by weight as follows: 45 to 55 percent of quartz sand, 12 to 16 percent of lime, 24 to 37 percent of cement, 5 percent of gypsum, 0.15 to 0.16 percent of aluminum powder and 0.1 to 0.3 percent of stabilized and enhanced type admixtures. According to the invention, an optimized basic formula is matched with the stabilized and enhanced type admixtures, so that products can be steadily produced and the strength of masonry blocks of the products reaches up to more than 1.8MPa, which is higher than the strength required by a class B03 product standard in the national standard. The inorganic nonmetallic light fireproof thermal insulation board has the advantages that the fireproof requirement is satisfied, the performance is steady, the construction cost is moderate, the outer thermal insulation manner of the prior building can be fundamentally changed from a sticky outer thermal insulation layer manner to a single material thermal insulation manner, and the occurrence of the phenomena of cracking is prevented; and the inorganic nonmetallic light fireproof thermal insulation board can have the same service life as the building.

Description

technical field [0001] The invention relates to an inorganic fire-proof and heat-insulating material, more specifically, the invention relates to a sand-entrained light-weight fire-proof concrete heat-insulating board conforming to the national standard GB / T11968-2006 and having a strength higher than B03 in the standard. Background technique [0002] In recent years, flammable and combustible external insulation materials for buildings have become a new type of fire hazard, and the fires caused by them have become frequent. Therefore, the Ministry of Public Security has put forward higher requirements for external insulation materials for civil buildings. With the development of science and technology and the enhancement of people's awareness of environmental protection, composite thermal insulation materials with high technological content, high performance and stability, and green environmental protection have become the focus and hot spot of domestic and foreign construct...
