Wall body placing heat-insulating mortar dry material and preparing method thereof

Abstract

The invention relates to thermal insulation mortar dry material for wall masonry, which is prepared by the following materials by weight proportion: 40-80 portion of silicon ore sintered material, 10-30 portion of shell-enwrapped aggregate, 18-20 portion of cement and 3-6 portion of additive. The thermal insulation mortar dry material has low thermal conductivity which is below 0.25W / (m.k) and can avoid the produce of cold-hot bridge on block joint, thus effectively forming a self-thermal insulation effect of building wall. At the same time, the thermal insulation mortar dry material had good cohesiveness and well anti-aging performance and can have the same life with the building; furthermore, the thermal insulation mortar dry material has the advantages of no poison, no pollution, no harm to human body, wide material source, low construction cost and simple construction which is ideal material for wall masonry.

Description

technical field [0001] The invention belongs to the technical field of building wall thermal insulation materials, and relates to an energy-saving wall masonry thermal insulation dry mortar material and a preparation method thereof. Background technique [0002] Insulation mortar is an important functional material in the field of building energy conservation. In recent years, with the implementation of "standards" for energy-saving design of civil buildings and the adjustment of national energy policies, people have higher requirements for the application and development of new insulation materials. One of the keys to realize building energy saving 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, in order to realize the thermal insulation of energy-saving building walls, not only lightweight thermal insu...

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) or more, 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 loss of thermal insulation energy of the wall caused by this is 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 attracted people's great attention, and has not been effectively solved. Therefore, it is very necessary to develop thermal insulation and energy-saving masonry mortar.
