Abstract

The invention provides a plant-derived polypropylene master batch. The plant-derived polypropylene master batch is prepared by mixing and melting polypropylene master batch and modified honeysuckle flower powder according to a mass ratio of 85:15. The invention also provides a preparation method of cellulose fiber. The prepared plant-derived polypropylene master batch has the advantages that the shape is regular, the connecting of particles is avoided, the crushed chips are avoided, the uniformity of particle size is 95.8 to 99.1%, and the OI (oxygen index) is 29 to 30. The prepared cellulosefiber has the advantages that the deviation rate of linear density is 0.7 to 1.2%, the deviation rate of length is 0.01 to 0.06%, the break strength is 7.9 to 8.3cN / dtex, the elongation rate at breakis 25.8 to 30.4%, the defect is 2.7 to 2.8mg / 100g, the combustion time of flame-retardant property is 9.4 to 8.5s, and the combustion class is V-1; after washing for multiple times, the flame-retardant effect is lasting and stable.

Description

technical field [0001] The invention relates to a plant-source polypropylene fiber masterbatch and a preparation method thereof, belonging to the field of fiber masterbatch preparation. Background technique [0002] Polypropylene masterbatch refers to the basic pellets for the manufacture of polypropylene fibers, which have certain physical and chemical properties such as shape and particle size. Polypropylene fiber is an important variety of synthetic fibers. It is the trade name of polyester fiber in my country. Polypropylene fiber has the advantages of low density, non-toxicity, corrosion resistance, good mechanical balance, and low price. It is a material with a wide range of applications. However, due to the poor flame retardancy of polypropylene itself, its application in motors, flexible circuit boards, electrical appliances and other fields is limited. [0003] Plants in nature, such as wormwood, Folium Folium, mint, honeysuckle, etc., are widely welcomed by technic...
