Problems solved by technology

Antibacterial by introducing metallic silver, and using chemical methods to maintain the antibacterial effect of silver, the operation is complicated and not conducive to environmental protection
[0006] PP has a large molecular weight, and the temperature is high during extrusion and granulation. Since plant extracts are easily carbonized in a high-temperature molten state, the content of active ingredients is greatly reduced, thus limiting the use of plants in PP products.

Abstract

The invention provides a preparation method of a plant-derived PP master batch. The preparation method comprises the following steps: S1, treating a porous nano-material; S2, preparing a plant extractsolution; S3, preparing a composite nano-material; and S4, preparing the plant-derived PP master batch. According to the invention, plant extract has good antibacterial and anti-inflammatory properties, and the porous nano-material is used as a skeleton and has a large specific surface area and a large loading capacity on the plant extract, and also has a slow release function, so effective sterilization, antibacterial and bacteriostatic time can be prolonged, prepared fibers, films and plastics have a long-acting bacteriostatic effect and a wide application range; and since the porous nano-material can be uniformly dispersed in PP slices due to small granularity, the mechanical properties of a prepared material are not influenced.

Description

technical field [0001] The invention relates to the technical field of PP materials, in particular to a plant-derived PP masterbatch and a preparation method thereof. Background technique [0002] Polypropylene, referred to as PP, is a thermoplastic resin prepared by propylene polymerization. It has high chemical stability, good heat resistance, chemical corrosion resistance and high wear resistance. It is widely used in fiber products, transportation Pipes and plastic products, etc. The polypropylene fiber prepared by it has the advantages of low density, non-toxicity, corrosion resistance, good mechanical balance and low price, and is the fourth largest variety of synthetic fibers. Masterbatch is a granular aggregate obtained by uniformly loading a super-normal amount of modified chemical additives in a carrier resin, which has certain physical and chemical properties such as shape and particle size. With the improvement of the quality of life, people are increasingly pu...
