Building thermal insulation mortar material taking gold tailings and oil sand tailings as raw materials as well as preparation method and application thereof

Abstract

The invention discloses a building thermal insulation mortar material taking gold tailings and oil sand tailings as raw materials as well as a preparation method and application of the building thermal insulation mortar material. The building thermal insulation mortar material is prepared from the following raw materials in parts by weight: 40-50 parts of gold tailings, 100-130 parts of cement, 20-30 parts of oil sand tailings, 20-30 parts of expanded perlite, 20-25 parts of gypsum, 2-5 parts of octenyl succinic acid aluminum starch, 6-10 parts of 2, 4-pentanediol, 3-6 parts of tridecyl trimellitate, 2-4 parts of lithium hydroxide, 7-9 parts of sodium hydroxide, 6-10 parts of kanuma soil, 1-2 parts of water glass and 10-15 parts of an air entraining agent. According to the invention, through reasonable design of the raw materials and the ratio thereof and synergistic effect of the raw materials, the thermal insulation mortar can be ensured to have good thermal insulation performance, waterproof performance and fireproof performance, and the workability and crack resistance of the thermal insulation mortar can be improved, so that the use effect of the thermal insulation mortar is improved; therefore, the thermal insulation mortar is more suitable for internal and external wall thermal insulation systems of buildings and has good social and economic benefits.

Description

technical field [0001] The invention relates to a building thermal insulation mortar material using gold tailings and oil sand tailings as raw materials, a preparation method and application thereof, and belongs to the technical field of building materials. Background technique [0002] In recent years, with the rapid development of my country's infrastructure construction and increasing energy consumption, building energy conservation has become an important topic in the construction industry. Since 2005, the state has issued a number of documents, putting forward new requirements for energy conservation. The document clearly requires new buildings to strictly implement the design standard of 50% energy saving, and cities with conditions are the first to implement the 65% energy saving standard. Therefore, under the premise of ensuring the use function and building quality, it has become a consensus in the industry to adopt various effective energy-saving technologies and ...
