Embodiment 1

[0038] Example 1 A preparation of honeysuckle PP masterbatch

[0039] 1.1 Experimental Example 1 Preparation of modified honeysuckle extract

[0040] Honeysuckle extract powder was selected as the plant source material of this embodiment. Mix 50 parts of honeysuckle extract powder with 15 parts of chitin and 4 parts of starch, add 50 parts of deionized water, adjust the pH to 7.1 with sodium carbonate, and heat to 51°C and mix for 30 minutes. The resultant is shaken. Distill under reduced pressure for 0.5 hours, then dissolve in 40 parts of deionized water, filter through a semi-permeable membrane for 0.8 hours, add 10 parts of acrylic acid into the internal mixer and mix for 1.0 hour, then dry naturally. Crush to obtain a modified honeysuckle extract. The prepared modified honeysuckle extract has good compatibility, the mesh number is 10000 mesh, and the density is 1.08-1.25g / cm 3 , The apparent viscosity is 30-50mPa.s, the cellulose content of honeysuckle is 20.7-26.0%, and the...

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...
