Abstract

The invention discloses an easily-degradable anti-shrinkage polypropylene master batch, wherein polypropylene serves as a base material, the types and the formula of the master batch are optimized, and a production process is improved. A complex antioxidant which contains a biologic antioxidant, modified nanocarbon which can obviously improve high temperature resistance, shrinkage resistance, relative tensile load, strength and toughness and elasticity modulus of the polypropylene master batch, calcium fruit fibers which can obviously improve shock resistance of the polypropylene master batch, are easily biodegradable and lower production cost, polyethylene / winter rye peptide complexes which can greatly improve low temperature resistance of the polypropylene master batch and bitter almond oil which can effectively improve lubricating property and oxidation resistance of the polypropylene master batch are scientifically compounded; the obtained compound has a synergistic effect with other processing aids; finally, the environment-friendly easily-degradable anti-shrinkage polypropylene master batch with good physical property is obtained.

Description

technical field

[0001] The invention relates to a polypropylene masterbatch, in particular to an easily degradable and shrink-resistant polypropylene masterbatch and a preparation method thereof. Background technique

[0002] Polypropylene is a general-purpose plastic with good comprehensive properties, and its total output has surpassed polyvinyl chloride to become the second largest general-purpose plastic after polyethylene. Main features: non-toxic, odorless, low density, strength, stiffness, hardness and heat resistance are superior to low-pressure polyethylene, high bending fatigue resistance, can be used at about 100 degrees. It has good electrical properties and high frequency Insulation is not affected by humidity, but becomes brittle at low temperature, not wear-resistant, and easy to age. Because of its notch sensitivity, low heat distortion temperature, large molding shrinkage, poor hardness and wear resistance, its application in product packaging, automobiles,...
