AI Technical Summary

Problems solved by technology

The carrier resin usually chooses non-polar polyolefin materials such as PE and polypropylene, and the filler often chooses polar inorganic fillers such as calcium carbonate and kaolin, but the compatibility between the two is poor, and it is difficult to form a good bond at the interface

The preparing method comprises the following steps: placing 6000-order inorganic material powder in the high-blender to stir and dehumidify; adding surface disposer in the cooling machine to cool; placing PE, polyethylene wax, paraffine and manufacturing adjuvant in the high-blender with modified 6000-order inorganic powder to cool; discharging; graining through squeezer.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a 6000-mesh inorganic powder-filled modified PE masterbatch and a preparation method thereof. Background technique [0002] With the rapid development of the plastics industry and the wide application of plastic products, people pay more and more attention to the technology of filling and modifying plastics. Adding various inorganic fillers to the resin and then mixing and molding can not only greatly reduce the cost of the product, but also significantly reduce the cost of the product. Improve certain properties of plastics, such as mechanical energy, thermal properties, wear resistance and aging resistance, so as to endow materials with new characteristics to meet the needs of different uses. [0003] PE (polyethylene) filler masterbatch includes three parts: carrier resin, filler and additives. The carrier resin usually chooses non-polar polyolefin materials such as...
