Abstract

The invention provides a preparation method of a flame-retardant isatis root PET master batch. The preparation method comprises the following steps: preparing an isatis root extract, preparing a modified isatis root extract, loading a modified substance, and preparing the isatis root PET master batch. The modified substance loading comprises the steps of preparing a loading agent, mixing the loading agent with a modified substance, carrying out heat treatment and carrying out reduced pressure distillation; in the step of preparing the loading agent, the adopted raw materials comprise diatomite, superfine bamboo charcoal powder, zinc stearate and sodium di-sec-octyl maleate sulfonate. According to the flame-retardant isatis root PET master batch prepared by the method, the isatis root extract is good in loading effect and good in antibacterial effect, and meanwhile, the flame-retardant isatis root PET master batch has flame-retardant and washable properties.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacture, and in particular relates to a flame-retardant isatis root PET masterbatch and a preparation method thereof. Background technique [0002] PET is a synthetic fiber, which is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. High polymer—polyethylene terephthalate (PET), a fiber made by spinning and post-processing. PET is widely used in various aspects such as clothing, decoration, home textiles, industrial textiles, national defense, and industrial engineering. Polyester fiber can be purely woven, or blended with cotton, wool, silk, hemp and other natural fibers and other chemical fibers, and can be processed into wool-like and cotton-like fabrics with various colors, easy to wash and dry, and non-ironing. , imitation silk and imitation linen and other fabri...
