Heat insulation mortar drier for wall masonry

Abstract

The invention relates to a heat insulation mortar drier for wall masonry. The heat insulation mortar drier is prepared from the following raw materials in part by weight: 15 to 20 parts of pottery sand, 5 to 8 parts of bentonite, 40 to 60 parts of converter slag granular material, 10 to 30 parts of shell expanded perlite heat insulation aggregate, 18 to 20 parts of cement, 20 to 50 parts of riversand, and 3 to 6 parts of redispersible emulsion powder. The heat insulation mortar drier has a low thermal conductivity coefficient and can avoid the cold and thermal bridge at the seam of a building stock at the thermal conductivity coefficient of less than 0.25W / (m.k), so that the self-insulation effect of the masonry wall is achieved. Meanwhile, the heat insulation mortar drier has high adhesion performance, high ageing resistance, the same service life as a building, and the advantages of nontoxicity, environment-friendliness, no harm to a human body, wide resource of raw material, low construction cost, convenience in construction and the like and is a very ideal wall masonry material.

Description

Technical field [0001] The invention belongs to the technical field of building wall thermal insulation materials, and is an energy-saving wall masonry thermal insulation mortar dry material. Background technique [0002] Insulation mortar is an important functional material in the field of building energy conservation. In recent years, with the implementation of civil building energy conservation design "standards" and the country's adjustment of energy policies, people have higher requirements for the application and development of new thermal insulation materials. One of the keys to achieving building energy conservation is to reduce the overall thermal conductivity of the wall, greatly improve the self-insulation performance of the masonry wall, and continuously develop and improve the self-insulation system of the masonry wall. However, to realize the insulation of energy-saving building walls, not only light-weight insulation blocks, but also masonry mortar with good insula...

Problems solved by technology

However, in the prior art, most of the bonding materials used for building heat-insulating lightweight walls are masonry mortars mixed with ordinary cement and engineering sand, which has the disadvantages of high density and poor heat preservation, and the general thermal conductivity is 0.93W / ( m.k) and above, due to the large gap between the thermal conductivity of this type of mortar and the lightweight thermal insulation block, a thermal bridge is formed in the masonry wall, and the resulting loss of wall thermal insulation energy reaches about 25%, which seriously affects The overall thermal insulation effect of the wall makes it difficult for the building to meet the thermal insulation and energy saving standards.

At present, this problem has not aroused people's great attention, and it has not been effectively solved. Therefore, it is very necessary to develop thermal insulation and energy-saving masonry mortar.
