Detailed Product Description: | In this paper, a situ polymerization filler / ultrahigh molecular weight polyethylene (UHMWPE) composites of high stiffness and high heat resistance; by intercalation polymerization processing montmorillonite (MMT), and then through the melt intercalation mixed system have a good overall performance of MMT / UHMWPE nanocomposites, and UHMWPE processing the modification of the exploration and study. The project is part of the project of Sinopec development purposes by filling Modification of lower material costs, an appropriate increase in the strength of the material. The study to the following aspects: First, by in situ polymerization on the filler of choice mineralization processing, to make their own polymerization active center or through the load so that the polymerization activity center, olefin monomers on aggregate required to fill and polyethylene molecular weight of the composite. The composite structure, crystallization behavior observed, to find the intrinsic relationship between structure and properties and characteristics, to establish the relationship between morphology and macro-mechanical properties is where the significance of our study. The results show that: in situ polymerization filling composite rigid than pure UHMWPE increased tensile strength than pure UHMWPE increased by more than 60% molybdenum disulfide and kaolin composites when the filler content of 10%, filling, glass bead content of 50%, 30% of the kaolin and diatomaceous earth content, the composite thermal deformation temperature has increased about 30 ℃. Second, by intercalation poly legitimate development of MMT / UHMWPE nanocomposites, the study found that: the distance between different layers of the structure of montmorillonite Montmorillonite with different monomer; intercalating agent processing can improve the monomer-rich The set of polymerization of the intercalated montmorillonite and ultra-high molecular weight polyethylene nanocomposites by melt blending can be obtained with excellent performance composites, the dry friction coefficient is less than pure of UHMWPE; zero shear viscosity of the composite material is significantly reduced. Again, modification of the processing of ultrahigh molecular weight polyethylene, low molecular weight processing modifier, such as polyethylene wax and stearic acid and calcium can significantly improve the processing performance of the UHMWPE; and low molecular weight LLDPE blends to improve its liquidity, but at the same time the mechanical properties are lower. |
