[发明专利]透明弹性理疗罐及其制造方法

权利要求书

1、一种透明弹性理疗罐，其特征在于配方成份如下(以重量计)：

(1)高聚合度PVC(P=4000)        100份

MBS                                                                                    6～20份

DOP                                                                                    80～150份

DBP                                                                                    0～70份

透明稳定剂                                                        2～6份

加工助剂                                                                0～3份

润滑剂                                                                        0.5～2份

着色剂                                                                        0～0.1份

(2)SBS                                                                        100份

环烷油                                                                        0～50份

PS                                                                                        0～30份

抗氧剂                                                                        0～1份

润滑剂                                                                        0.1～1份

2、根据权利要求1所述的理疗罐，其特征在于透明稳定剂为有机锡和金属皂，润滑剂为EBS。

3、一种透明弹性理疗罐的制备方法，其特征在于工艺流程为：原料称量→混合→造粒→切粒、风冷→成型（中空吹塑、注塑）→检验→成品。

造粒温度一区80℃～100℃，二区130℃～150℃，三区170℃～180℃，四区170℃～185℃，机头170℃～180℃，造粒机转速15～50rpm;成型各区温度用PVC生产比造粒温度高20℃～30℃，用SBS生产比造粒温度高10℃。
