Additive for thermal insulation material and application thereof
The invention discloses an additive for a thermal insulation material and application of the additive. The problem that in the prior art, an additive applied to a heat preservation material cannot remarkably improve the heat insulation effect under the high-temperature condition is solved. The additive provided by the invention comprises 30%-45% of polyacrylamide, 30%-45% of polyvinyl alcohol andthe balance of rare earth substances. The rare earth substances are cerium nitrate and lanthanum chloride. The heat conductivity coefficient of the heat preservation material under the high-temperature or low-temperature condition can be remarkably reduced, and the good heat insulation effect can still be effectively achieved in the high-temperature or low-temperature environment.
本发明公开了一种保温绝热材料用添加剂及其应用。本发明克服了现有技术中应用于保温材料中的添加剂并不能在显著提高高温条件下隔热效果的问题。本发明中的添加剂包括30％‑45％聚丙烯酰胺、30％‑45％的聚乙烯醇，以及剩余量的稀土物质；所述稀土物质为硝酸铈和氯化镧。本发明能够同时显著降低保温材料在高温或低温条件下的导热系数，在高温或低温环境中依然能有效达到很好的隔热效果。
