Low-thermal-conductivity thermal insulation material as well as preparation method and application thereof
The invention provides a low-heat-conductivity thermal insulation material as well as a preparation method and application thereof. Relates to the field of building wall insulation boards. The preparation method comprises the following steps: compounding tetraethoxysilane and barium sulfate to prepare an infrared-visible light reflecting agent, and preparing the infrared-visible light reflecting agent into steeping liquor with an infrared-visible light reflecting function; then, the impregnation liquid with the infrared-visible light reflection function is permeated into the polystyrene foam thermal insulation material through an impregnation production process to prepare the low-thermal-conductivity thermal insulation material, so that the thermal conductivity coefficient of the polystyrene foam board is greatly reduced and is controlled to be 0.03 W/(m.K) or below, and the thermal conductivity coefficient of the polystyrene foam board is controlled to be 0.03 W/(m.K) or below. The problems that when an ultra-low energy consumption building is built, walls are too thick, and the housing area is reduced are solved.
本发明提供了一种低导热保温材料、制备方法及应用。涉及建筑墙体保温板领域。将正硅酸乙酯与硫酸钡复合制备出一种红外‑可见光反射剂，并将其配制成具有红外‑可见光反射功能的浸渍液。然后通过浸渍的生产工艺，在聚苯乙烯泡沫保温材料内部渗透入这种具有红外‑可见光反射功能的浸渍液，制备得到低导热保温材料，从而大幅降低聚苯乙烯泡沫板的导热系数，将其导热系数控制在0.03W/(m·K)以下，来解决超低能耗建筑在建造时墙体太厚，住房面积减小的问题。
