Abstract

The invention provides a heat-insulating energy-saving flame-retardant material for an external wall, relating to the technical field of construction materials and aiming to solve the technical problems that the conventional external wall insulating materials have poor fireproof flame-retardant performance, and release mass toxic smoke after burnt, and the like. The insulating energy-saving flame-retardant material consists of the following components in parts by weight: 700 to 800 parts of spherical closed-pore expanded perlite, 600 to 700 parts of conventional silicate cement, 200 to 300 parts of heavy calcium carbonate, 3 to 5 parts of flame retardant, 6 to 8 parts of water-retaining thickener, 5 to 7 parts of dispersible emulsion powder, and 1 to 3 parts of polypropylene monofilament fibers.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation, energy saving and flame retardant material for exterior walls. Background technique [0002] According to statistics, more than 50% of the material materials obtained by humans from nature are used to build various buildings, and these buildings consume about 50% of the world's energy in the process of construction and use. After the global oil crisis in 1973, many developed countries realized the importance of building energy conservation, successively formulated and implemented special laws on energy conservation, and devoted themselves to the research and implementation of building energy conservation technologies. Now, while the comfort of buildings in these countries is constantly improving, the energy consumption per unit area of ​​new buildings has been reduced to one-third to one-fifth of what it was more than 30 years ago. In addition, t...
