Abstract

The invention provides an enhanced plastic filling lubrication master batch and a preparation method thereof. The preparation method comprises the following steps: utilizing selected specially salt as intercalator to carry out embrittlement on a laminated silicate intercalation, and weakening the interlamellar Van der Waals force of the laminated silicate so as to be easy in hierarchical refinement; then, through ultra-fine grinding equipment, smashing peeling energy, and carrying out layer-by-layer peeling refining on the laminated silicate of which the intercalation is modified; especially, through salt embrittlement, enabling a layer interface to own reaction activity, enabling the layer of the laminated silicate to own good dispersibility, sliding performance and compatibility with polyethylene through further graft modification of styrene monomer and maleic anhydride, and carrying out extrusion palletization to obtain the enhanced plastic filling lubrication master batch. As the master batch in plastic processing, the silicate layer with good dispersion can accelerate the machining lubricity of a plastic product, in addition, a compact connection surface can be extremely formed, and the master batch shows excellent wearproof enhancement in the plastic product. The defects that lubrication and enhancement can not be both given consideration in plastic product machining are solved.

Description

technical field [0001] The invention relates to the field of plastic materials, in particular to a reinforced plastic filling lubricating masterbatch and a preparation method thereof. Background technique [0002] With the rapid development of the plastics industry and the wide application of plastic products, more and more people pay attention to plastic filling technology.
