ZL02133295.5 announces a kind of "external wall masonry insulation brick", which uses perlite and fly ash as insulation materials, and cement as bonding and coagulant to make external wall blocks, so that the external wall body does not need Then make another inner and outer insulation layer, so that the masonry and insulation can be completed at one time, without adding another process, but the insulation performance of the insulation brick is not high enough, and its thermal conductivity only reaches 0.103w / (m·k)
[0003] In addition, according to the characteristics of building materials, while improving the thermal insulation performance of the material, the performance and indicators of the material in terms of strength, light weight, fire resistance, service life, and convenient construction cannot be reduced. This poses a severe challenge to the development of external wall insulation. challenges because wall insulation is often at odds with its strength, light weight, fire performance, longevity and construction performance

Abstract

The invention discloses a cement-based composite self-heat-insulation high-strength energy-saving building block. The building block comprises a building block body which is provided with a heat-insulation cavity, wherein the width of an upper cavity of the heat-insulation cavity is greater than or equal to the width of a lower cavity of the heat-insulation cavity; the building block is prepared from ordinary silicate cement, industrial waste residues, high-strength heat-insulation materials and a multifunctional additive. The building block has the beneficial effect that the heat insulation effect is good, other heat insulation measures are not additionally carried out in a construction process, meanwhile, the fireproof performance is good, and the compressive strength is high; furthermore, the bonding strength is high in a mounting process, the hollowing and the falling are less easily to occur, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of new green building materials, in particular to a self-insulating high-strength energy-saving block. Background technique [0002] In recent years, building energy conservation has become an important aspect of my country's implementation of energy conservation and emission reduction measures. At present, the exterior wall building materials used in northern China require their energy-saving effect to reach 65%, which puts forward higher requirements for the thermal insulation performance of exterior wall building materials. ZL02133295.5 announces a kind of "external wall masonry insulation brick", which uses perlite and fly ash as insulation materials, and cement as bonding and coagulant to make external wall blocks, so that the external wall body does not need Then make another inner and outer insulation layer, so that the masonry and insulation can be completed at one time, without adding another proce...
