The invention relates to a polyurethane foam-PMI foam composite missile adapter and a preparation method thereof. The method comprises the preparation steps that a rib plate mounting groove is formed in one face of a PMI foam thin plate, a rib plate is bonded in the rib plate mounting groove, a guide rail connecting groove is formed in the other face of the PMI foam thin plate, a PMI foam thick plate is bonded to the face, provided with the rib plate mounting groove, of the PMI foam thin plate, and machining forming is conducted according to the shape of the adapter. A missile separation device mounting groove communicating with the rib plate is formed at the top of the PMI foam thick plate, and PMI foam embedded with the rib plate is obtained; and the inner wall of a mold is coated with a release agent, the position, corresponding to a guide rail mounting groove, of the mold is paved with an antifriction film, the PMI foam embedded with the rib plate is loaded into the mold, a glue injection gap is formed between the outer wall of the PMI foam embedded with the rib plate and the inner wall of the mold, polyurethane foam materials are injected into the glue injection gap, and the missile adapter is obtained after curing and demolding. The obtained adapter is light in weight, good in creep resistance and good in damping effect.
本发明涉及一种聚氨酯泡沫‑PMI泡沫复合型导弹适配器及其制备方法;包括制备步骤:在PMI泡沫薄板一面开设筋板安装槽,将筋板粘结于筋板安装槽内,在PMI泡沫薄板另一面开设导轨连接槽,在设有筋板安装槽一面的PMI泡沫薄板上粘结PMI泡沫厚板,按照适配器形状加工成型,在PMI泡沫厚板顶部开设与筋板连通的导弹分离装置安装槽,获得内嵌筋板的PMI泡沫;模具的内壁涂覆脱模剂,在模具对应导轨安装槽的位置铺设减摩薄膜,将内嵌筋板的PMI泡沫装入模具中,内嵌筋板的PMI泡沫外壁和模具内壁间设有注胶间隙,将聚氨酯泡沫料注入注胶间隙内,固化,脱模后获得导弹适配器;获得的适配器质量轻,抗蠕变性好,具有较好的减震效果。
