一种提高超声波焊接强度的聚丙烯材料及其制备方法
摘要：
本发明公开了一种提高超声波焊接强度的聚丙烯材料及其制备方法，按重量百分计，由以下组分制成：聚丙烯43～95％；弹性体2～20％；滑石粉1～30％；抗氧剂0.1-2％；活化剂氧化镁1～3％；色粉1～2％。本发明通过在配方中添加一种活化剂氧化镁，该物质在焊接面能够促进超声波能量的传导及热量的吸收，进而提高焊接面焊接强度。
摘要（英）：

The invention discloses a polypropylene material for improving ultrasonic welding strength and a preparation method of the polypropylene material. The polypropylene material is prepared from the following ingredients by weight percentage: 43-95% of polypropylene, 2-20% of elastomer, 1-30% of talcum powder, 0.1-2% of antioxidant, 1-3% of magnesium oxide activator and 1-2% of toner. The magnesium oxide activator is added in a formula and can promote ultrasonic energy conduction and heat absorption on a welding face, and the welding strength of the welding face is improved.
