Nano-based polyester heat insulation paste and preparation method thereof

The invention discloses nano-based polyester heat insulation paste and a preparation method thereof. The raw materials comprise a component A and a component B in equal proportions, wherein the component A is a mixture of nano-sized vitrified microbeads and combined polyether in a ratio of 10-14:100; the component B is a mixture of nano-sized vitrified microbeads and isocyanate in a ratio of 10-14:100. The nano-based polyester heat insulation paste has the beneficial effects that the applicable temperature is subzero 100DEG C-200 DEG C, fire prevention grade is B1, no pollution is produced during construction, thermal conductivity is lower than or equal to 0.027 w/m.k, and thermal insulation can be achieved for any special-shaped structure in industry. 本发明公开了一种纳基聚酯隔热膏及其制备方法，原料包括等比例的组分A和组分B，其中：组分A为纳米级的玻化微珠与组合聚醚按比例混合，组合聚醚：玻化微珠=100:10-14；组分B为纳米级的玻化微珠和异氰酸酯按比例混合，异氰酸酯：纳米材料=100:10-14。本发明的有益效果为：本发明的纳基聚酯超级隔热膏，适用温度：-100-200℃，防火等级B1级，施工时无污染，导热系数小于等于0.027 w/m·k，可做到工业任何异形结构保温。
