Special mineral filler for polypropylene bumper as well as preparation method and application of special mineral filler
The invention provides a special mineral filler for a polypropylene bumper as well as a preparation method and application of the special mineral filler. The particle size and the crystal structure of the byproduct gypsum are accurately regulated and controlled through a ball milling-calcination combined method, a filler powder raw material is obtained, then the filler powder raw material is modified through an organic modifier, modified superfine powder is obtained, and the special mineral filler for the polypropylene bumper is obtained. The special mineral filler for the polypropylene bumper is mixed with polypropylene, and the mixture is extruded and granulated by an extruder to obtain the special material for the polypropylene bumper. The polypropylene bumper special material provided by the invention has excellent tensile fracture strain and impact strength and excellent comprehensive mechanical properties, and meets national standard requirements. The preparation process disclosed by the invention is simple and easy to implement, has low requirements on equipment and is easy for industrial production. Special protection is not needed in the preparation process, and the method is environment-friendly, so that technical support is provided for comprehensive utilization and high-value utilization of the byproduct gypsum.
本发明提供了一种聚丙烯保险杠专用矿物填料及其制备方法与应用。通过球磨‑煅烧联合法精准调控副产石膏粒径大小和晶体结构，得到填料粉体原料，然后通过有机改性剂对填料粉体原料改性得到改性超细粉体，即得到聚丙烯保险杠专用矿物填料；将聚丙烯保险杠专用矿物填料与聚丙烯混合，经挤出机挤出造粒，得到聚丙烯保险杠专用料。本发明提供的聚丙烯保险杠专用料呈现极佳的断裂拉伸应变和冲击强度，综合力学性能优异，满足国标要求。本发明的制备工艺简单易行，对于设备的要求不高，易于工业化生产。制备过程中不需要特殊的保护，且对环境友好，这为副产石膏的综合化利用和高值化利用提供技术支持。
