Embodiment 1

[0049] Embodiment 1 raw material preparation

[0050] 1. Preparation of calcium fruit fiber:

[0051] The preparation method of the calcium fruit fiber comprises the following steps: uniformly mixing fresh calcium fruit stems, calcium fruit leaves and waste sawdust at a mass ratio of 7:4:1.5, placing them in an ultrasonic cleaning machine at 200W and 30KHz for cleaning for 4 minutes, draining Drying, crushing, adding water with 1 times the amount of the crushed material, ultrasonic extraction at room temperature 300W, 40KHz for 12min, and then performing high-voltage pulse electric field treatment for 12min under the conditions of electric field strength 30kV / cm, pulse time 500μs, and pulse frequency 300Hz; adjust the pH value 8. Add biological enzyme with 0.2% mass of the mixture, and enzymatically hydrolyze at 55°C for 12 minutes; the enzymolyzed solution is concentrated under reduced pressure to a solid content of 50%, and placed in a microwave dryer at 2000W and 140°C for ...

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,...
