Description
Technical Field
The invention relates to the technical field of heat insulation materials, in particular to a polyphenyl particle-aerogel composite cement-based heat insulation material.
Background
With the rapid development of productivity, the global consumption of energy resources is higher and higher. China is in the rush hour of urban construction, and building energy conservation becomes one of the important fields of energy conservation and emission reduction in China. At present, the energy consumption of buildings is mainly reduced by the following four ways: firstly, the heat preservation and heat insulation performance of the building is improved; secondly, the efficiency of energy utilization systems such as heating, air conditioning, illumination and the like is improved; thirdly, new energy and renewable energy are reasonably utilized; fourthly, operation management of the enhanced energy utilization equipment system. Among them, it is the most effective way to enhance the thermal insulation of a building to reduce the heat consumption of the building.
The related data show that the heat dissipation loss of the enclosure structure in the building energy consumption reaches 40-50%, and the heat dissipation loss of the wall body accounts for about 70% of the heat dissipation loss of the enclosure structure, so that the heat insulation performance of the wall body is improved, the building energy consumption is reduced, and the building energy saving work is completed. For buildings in hot summer and cold winter regions, in order to achieve the aim of building energy conservation, the maintenance structure of the building needs to take heat preservation measures and also needs to implement heat insulation measures, and the heat preservation measures are usually realized by matching building reflective heat insulation coatings with proper heat preservation layers. However, when the system of the outer wall outer insulation layer and the building reflective insulation coating is adopted, the traditional insulation mortar has insufficient insulation performance, so that the building energy-saving requirement is difficult to meet, or when the system is applied to high-rise buildings, the insulation layer is unsafe when the system can meet the building energy-saving requirement. Therefore, there is a need to develop a new external wall thermal insulation material with more advanced performance and better thermal insulation effect, which can be used with reflective thermal insulation coating of buildings.
The aerogel has a three-dimensional nano porous structure, high porosity, light weight, extremely low density, high heat insulation and non-inflammability, and is a novel building heat-insulating material. The proper amount of aerogel is introduced into the traditional cement-based polyphenyl particle heat insulation material system, so that the heat insulation performance, the mechanical property and the like of the heat insulation material can be obviously improved. However, the aerogel has poor dispersibility and compatibility in a cement-based polyphenyl particle heat insulation material system, so that the improvement effect of the aerogel on the performance of the heat insulation material is limited, and the cost is increased.
