Flame-retardant polyurethane foam thermal insulation material as well as preparation method and application thereof
The invention provides a flame-retardant polyurethane foam thermal insulation material and a preparation method and application thereof.The flame-retardant polyurethane foam thermal insulation material is prepared from a component A and a component B according to the volume ratio of 1: 1-1: 1.3, and the component A is prepared from, by mass, 65-88 parts of polyether polyol; 0.2 to 1.0 part of a catalyst; 7 to 15 parts of a first flame retardant; the component B is prepared from the following components in parts by weight: 65 to 80 parts of polyphenyl polymethylene polyisocyanate; 15 to 35 parts of a second flame retardant; the composite foaming agent comprises fly ash and water in a mass ratio of (6-8): 1, and the composite foaming agent mainly composed of fly ash and water is adopted to cooperate with other components in a specific ratio, so that internal holes are uniform, excellent mechanical properties are achieved, the limit oxygen index is increased, the flame retardance is improved, meanwhile, excellent heat-conducting property is achieved, and the service life of the composite foaming agent is prolonged. The requirements of building thermal insulation materials can be effectively met.
本申请提供了一种阻燃聚氨酯泡沫保温材料及其制备方法和应用，该阻燃聚氨酯泡沫保温材料包括体积比为1:1～1:1.3的A组份和B组份，A组份按照质量份数计包括：聚醚多元醇：65～88份；催化剂：0.2～1.0份；第一阻燃剂：7～15份；复合发泡剂：5～20份，B组份包括：多苯基多亚甲基多异氰酸酯：65～80份；第二阻燃剂：15～35份；复合发泡剂包括粉煤灰和水，两者的质量比为6～8:1，通过采用主要由粉煤灰和水组成的复合发泡剂与特定配比的其他组分相互协同，不仅内部孔洞均匀，具有优异的力学性能，而且，提高了极限氧指数，改善了阻燃性，同时还具备优异的导热性能，能够有效满足建筑保温材料的要求。
