液体石蜡与凹凸棒土对聚丙烯力学性能影响的研究

以液体石蜡与凹凸棒土加入到聚丙烯并对力学性能的影响进行研究。将凹土与液体石蜡和聚丙烯在高速混合机中进行混合,再在挤出机中熔融挤出,注塑成型,研究液体石蜡与凹凸棒土对聚丙烯力学性能的影响。研究结果表明：液体石蜡和经硅烷偶联剂处理过的凹土能比较显著的提高PP的综合力学性能,当PP的用量为100份,凹土的用量为20份,LP为10份时拉伸强度及硬度性能最好。此时,拉伸强度为34.63 MPa,硬度为63.30。当PP的用量为100份,凹土的用量为20份,LP为20份时冲击强度最好,为11.11 kJ/m^2。

Research on the Influence of Liquid Paraffin and Attapulgite to Mechanical Properties of Polypropylene

In this paper, liquid paraffin and attapulgite clay are added to affect the mechanical properties of polypropylene. The attapulgite clay and liquid paraffin and polypropylene were mixed in a high speed mixer, and then in the extruder melt extrusion, injection molding, and study the impact on the mechanical properties of polypropylene. The results show that：liquid paraffin and attapulgite treated by a silane coupling agent can significantly improve the overall mechanical properties of PP, when the PP amount of 100 parts, the amount is 20 parts attapulgite, LP is 10 parts , tensile strength and hardness is the best performance. At this time, the tensile strength is 34. 63 MPa, and hardness of 63. 30. The impact strength is 11. 11kJ/m^2 when the PP in an amount of 100 parts, the amount of at-tapulgite is 20 parts and the amount of LP is 20 parts.
