Problems solved by technology

The carrier resin is PA6, and the filler often uses 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
In order to improve the interfacial bonding between the resin and the inorganic filler, and form a good interfacial adhesion between the resin and the inorganic filler, the mechanical and dimensional stability of the whole system after the masterbatch is mixed with the matrix resin cannot meet the ideal requirements.

Abstract

The invention discloses a 6000-mesh inorganic powder-filled modified PA (Polyamide)6 master batch and a preparation method thereof and belongs to the technical field of high-molecular materials. The PA6 master batch comprises the following main raw materials: PA6, a surface treating agent, polyethylene wax, paraffin wax and 6000-mesh inorganic powder, and the preparation method of the PA6 master batch comprises the following steps of: putting the 6000-mesh inorganic powder into a high-speed mixer for agitation and dehumidification, adding the surface treating agent for mixing and agitation and putting in a cold mixer for cooling, putting the PA6, the polyethylene wax and the paraffin wax into the high-speed mixer in sequence for mixing and agitation, adding the modified 6000-mesh inorganic powder for mixing and agitation, putting in the cold mixer for cooling and discharging and pelleting with an extruder to prepare the 6000-mesh inorganic powder-filled modified PA6 master batch. The 6000-mesh inorganic powder-filled modified PA6 master batch and the preparation method thereof have the beneficial effects that after the 6000-mesh inorganic powder-filled modified PA6 master batch is mixed with matrix resin, a whole system has good compatibility, dispersibility, flowability and processing performance, and a produced product has good mechanical property, dimension stability, toughness and impact resistance and the 6000-mesh inorganic powder-filled modified PA6 master batch is particularly suitable for manufacturing PA6 water supply pipes, PA6 double-walled corrugated tubes, plastic turnover boxes and automotive interior products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a 6000-mesh inorganic powder filled modified PA6 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] PA6 (Nylon 6) filler masterbatch includes three parts: carrier resin, filler and additives. The carrier resin is PA6, and the filler often uses polar inorganic fillers...
