摘要
Abstract
Homemade agent-tetrahydrofuran polyether (PTHF) was used to treat the surface of the precipitated calcium carbonate.The impacts of surface modified CaCO3 with coupling agent of PTHF on CaCO3/PP mechanical properties of composite material were studied.The result showed that tetrahydrofuran polyether was able to make the oil absorption of calcium carbonate reduced to 22％ and the contact angle decreased to 68.6°.CaCO3 with PTHF filling in the polypropylene can also alleviate the downward trend of the tensile strength to a certain extent,making the elongation at break of composites reached 28.47％ and the impact strength of the composites reached 6.7 kJ/m2.Calcium carbonate with PTHF dispersed better in polypropylene than calcium carbonate by scanning electron microscopy (SEM).关键词
