Abstract

The invention belongs to the field of building materials, relates to a use of a nano-material in a building exterior wall heat-retaining system and provides a nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face brick. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face brick is characterized in that nano-particles are used so that compressive strength, tensile strength and bonding strength are improved. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face brick is prepared by adding a nano-material having a nanoscale particle size into a mixed system of cement, an auxiliary gel material, a polymer binder, an inorganic light heat-retaining material, fibers and water, uniformly mixing, carrying out pressing molding of the mixture, carrying out organic polymer crosslinking and cement hydration drying, and carrying out waterproof layer coating. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face brick has the advantages of excellent flame resistance, high compressive strength, high tensile strength, high bonding strength and good insulation effects.

Description

technical field [0001] The technology belongs to the field of building materials, in particular to the application of nanometer materials in building exterior wall insulation systems. Background technique [0002] The development of energy-saving buildings is an important way to solve resource and energy problems. Taking China as an example, there are 44 billion square meters of existing buildings in China, and energy consumption is generally high. Building energy consumption generally accounts for 30% of the total energy consumption of the society, plus the consumption of the production process of building materials, the proportion of the total energy consumption of the society reaches 46% to 47%. Among them, the heating energy consumption per unit area of ​​buildings in the northern region is 1.5 to 2 times higher than that of European countries with similar climate conditions. Among the nearly 2 billion square meters of completed area each year, only 50 to 60 million sq...
