When the existing reflective thermal insulation coating for buildings is applied to the building energy-saving engineering in hot summer and cold winter areas, a thermal insulation layer needs to be configured to meet the requirements of thermal insulation. For example, expanded polystyrene board, extruded polystyrene board, or conventional building insulation mortar is used as the insulation layer. The formed external thermal insulation system of the external wall often causes cracking and water seepage of the external thermal insulation system of the external wall due to poor anti-cracking performance of the anti-cracking protective layer or poor dimensional stability of the thermal insulation layer.
In recent years, a plurality of experts and scholars research the influence of various components of the inorganic thermal mortar on the performance of the thermal mortar so as to improve the performance index of the inorganic lightweight aggregate polymer thermal mortar. Researches show that the strength of the thermal insulation mortar can be improved and the heat conductivity coefficient can be reduced by replacing traditional aggregates such as expanded perlite and the like with aggregates with better performances such as vitrified micro bubbles and the like, the bonding tensile property of the mortar can be greatly improved by means of adding high molecular compounds such as polymers and the like, and the polymers have great influence on the performance of the freshly mixed thermal insulation mortar.
Silica aerogel is a new type of light nano-porous material which appears in recent years, is the lightest and best-performing heat insulator in the currently known solid substances, has hydrophobicity, and more than 90 percent of the volume of the silica aerogel is formed by tiny nano-pores. The silica aerogel and the vitrified micro bubbles are compounded to form reasonable grain composition, so that the comprehensive performance of the mortar is optimized. Therefore, the novel composite aggregate thermal insulation mortar which meets the performance requirements of relevant mechanics and durability and also meets the requirement of low thermal conductivity coefficient can be developed.
The related engineering examples show that the reflective heat-insulating coating is easy to fall off in a large area under the long-term scouring action of rainwater. The silicon dioxide epoxy resin composite material is a hybrid material with excellent properties, integrates the dual advantages of inorganic materials and organic materials, and has the advantages of high rigidity, good thermal stability, good toughness, plasticity, easy processability and the like. Meanwhile, when the mass fraction of the silicon dioxide is increased to a certain amount, the prepared silicon dioxide epoxy resin composite coating has good hydrophobicity.
