Problems solved by technology

[0012] Most of the high temperature and low temperature resistant patents disclosed above are modified high temperature resistant polypropylene. It is less than the requirements for the use of raw materials, which limits the application field. At the same time, inorganic salts such as calcium carbonate, nano-calcium carbonate and silicate (clay, actinolite, etc.) are used as fillers, which are not easy to biodegrade and easily alkalize the soil. cause serious environmental pollution

Abstract

The invention discloses a polypropylene master batch, and belongs to the technical field of polypropylene materials. The polypropylene master batch is characterized in that polypropylene is used as the base material; the types of the raw materials of the master batch and the formula are optimized; the production technology is improved; calcium fruit fibers which are capable of obviously improvingthe impact resistance of the polypropylene master batch and are easily biodegraded and are low in production cost, a modified nanotube which is capable of obviously improving the high temperature resistance, the relative stretching load, the strength, the toughness and the elastic modulus of the polypropylene master batch, a polyethylene / fall rye peptide compound which is capable of greatly improving the low temperature resistance of the polypropylene master batch, and bitter almond oil and a composite antioxidant which are capable of effectively improving the lubricating performance and theoxidation resistance of the polypropylene master batch are scientifically compounded; and other processing additives synergize to prepare the environmentally-friendly polypropylene master batch with high physical performance.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a 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, household appliances, construction and oth...
