氯丁橡胶和三元乙丙橡胶并用可以制得烧蚀性能优良的橡胶绝热层,并在型号为MX的地地战略导弹的第三级发动机内绝热层中获得应用。美国专利公布的火箭发动机低密度热塑弹性体耐烧蚀绝热层也是采用Phos2Chek.RTM.P240(氨基聚磷酸盐)作为阻燃剂,并配合Crilamid.RTM.EL Y2742(尼龙12),采用传统的密炼机将组分混合均匀,最后绝热层在350℉进行模压所得绝热层的密度为1.03 g/cm~3。国外Thikol
The combination of neoprene and EPDM results in a rubber ablative layer with excellent ablation properties and is used in the third engine internal insulation for the MX-based surface to air missile. The rocket engine low-density thermoplastic elastomer ablative insulation disclosed in the U.S. patent also uses Phos2Chek.RTM.P240 (aminopolyphosphate) as a flame retardant in combination with Crilamid.RTM.EL Y2742 (nylon 12) Of the mixer to mix the components evenly, and finally the insulation layer is molded at 350 ° F to obtain a density of 1.03 g / cm ~ 3.
