Problems solved by technology

Because the silver ion antibacterial agent is used in a large amount and has high hardness, after it is added to the compatibilizer masterbatch, it will be mechanically worn with the screw extruder equipment (such as extrusion screw) during the preparation process, resulting in discoloration of the compatibilizer masterbatch

Abstract

The invention provides an antimicrobial compatibilizer masterbatch suitable for the production of downstream inorganic filler modified PP and its preparation method and application. Through the adjustment of the preparation process parameters, the compatibility of inorganic fillers in the production of downstream filler modified PP plastics can be solved at the same time. The problem of antibacterial properties and the uniformity of antibacterial content, as well as the discoloration problem caused by the silver ion antibacterial agent in the compatibilizer masterbatch; the inorganic filler modified PP can be used in the production of vehicle plastic parts.

Description

technical field [0001] The invention belongs to the field of polypropylene macromolecular materials, in particular to an antibacterial compatibilizer masterbatch suitable for inorganic filler modified PP materials, and the inorganic filler modified PP can be used for the production of vehicle plastic parts. Background technique [0002] Polypropylene (PP) is a thermoplastic resin obtained by polymerizing propylene. Due to the regular molecular structure of PP, PP has many defects in terms of toughness, surface hardness, and scratch resistance. Filling modification is to add relatively cheap non-metallic mineral powder materials or other materials to plastics, thereby reducing the cost of raw materials for products, and at the same time improving certain properties of plastic materials. Poor compatibility between polypropylene and inorganic fillers leads to poor composite properties. Adding compatibilizer to inorganic material filled modified polypropylene is an effective w...
