Problems solved by technology

[0003] Of course, PP plastic products have poor thermal stability and are prone to aging. The main reason is that the structure of PP is very sensitive to oxygen. Under the multiple effects of heat and ultraviolet rays, oxidative decomposition and photodecomposition occur, which eventually leads to PP products becoming brittle and discolored. Changes, in summary, in the prior art, the prepared PP masterbatch has the following deficiencies:
[0004] 1. In the process of preparing PP masterbatch, the functional substances added have poor heat resistance, and are easy to react under high temperature, generate bubbles, and affect the quality of the masterbatch
[0005] 2. Poor thermal stability, sensitive to light and ultraviolet rays, yellowing and reduced strength after long-term use

Description

technical field [0001] The invention relates to the technical field of PP master batches, in particular to a wormwood PP functional master batch and its application in plastic products. 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 functional substances in a carrier resin, which has certain physical and chemical properties such as shape and particle size. [0003] Of course, PP plastic products have poor thermal stability and are prone t...
