一种阻燃型硬质聚氨酯结构保温环保泡沫塑料的制备方法
摘要：
本发明公开了一种阻燃型硬质聚氨酯结构保温环保泡沫塑料的制备方法，由以重量计算的聚醚多元醇80-150份、聚合物多元醇15-20份、多异氰酸酯15-20份、胶质碳酸钙3-6份、丙烯酸酯类共聚物10-14份、己内酰胺4-8份、无卤阻燃剂3-6份、扩链剂1-4份、匀泡剂3-5份、催化剂0.5-2份、复合发泡剂7-9份制备而成，应用到家具以及其他对硬度要求较高的泡沫塑料制品中去，不仅硬度高，阻燃性能好，且不含卤族元素和重金属，健康低碳，满足了对安全和环保的双重要求。
摘要（英）：

The invention discloses a preparation method of flame-retardant rigid-polyurethane structured thermal insulation foam plastics. The flame-retardant rigid-polyurethane structured thermal insulation foam plastics is prepared from, by weight, 80-150 parts of polyether polyol, 15-20 parts of polypolyols, 15-20 parts of polyisocyanates, 3-6 parts of calcene, 10-14 parts of acrylate copolymers, 4-8 parts of caprolactam, 3-6 parts of a halogen-free flame retardant, 1-4 parts of a chain extender, 3-5 parts of a foam stabilizer, 0.5-2 parts of a catalyst and 7-9 parts of a composite foaming agent. The flame-retardant rigid-polyurethane structured thermal insulation foam plastics applied to furniture and other foamed plastic products high in rigidity requirement is high in rigidity, good in flame retardance, free from halogen elements and heavy metals and healthy and low in carbon, and dual requirements in safety and environmental protection are met.
