Plant-derived PP master batch, preparation method and application thereof

Abstract

The invention provides a plant-derived PP master batch, a preparation method and application thereof. According to the method, anti-carbonization additives chitin and starch are added into plant extract powder, and a modified plant extract is obtained after internal mixing of an internal mixer, so that carbonization in the subsequent high-temperature melting process is reduced; and the modified plant extract and PP slices are blended and melted to prepare plant-derived PP master batches, and products containing the modified plant extract, such as polypropylene fibers, films or plastics, are prepared through spinning, injection molding, extrusion, blow molding, thermal forming and other methods. According to the invention, the plant-derived PP master batch is uniform in particle and smoothin surface; the prepared product has the advantages that the mechanical property is reduced, the normal use is not influenced, the functions of fragrance, antisepsis, anti-inflammation, cooling, health care and the like of plants can be realized, the moisture regain of the prepared polypropylene fiber is improved, and the comfort is enhanced.

Description

Technical field [0001] The invention relates to the field of resins, in particular to a plant-derived PP master batch and a preparation method and application thereof. Background technique [0002] Polypropylene is abbreviated as PP. It is a thermoplastic resin made by polymerization of propylene. It has high chemical stability, good heat resistance, chemical corrosion resistance, and high wear resistance. It is widely used in fiber products and 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. The masterbatch is a granular aggregate obtained by uniformly loading an ultra-constant amount of modified chemical additives in the carrier resin, which has certain physical and chemical properties such as a certain shape and particle size. With the improvement of the quality of life, pe...

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

[0005] 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.
