Abstract

The invention discloses a master batch used for preparing high heat-resisting polypropylene plastic as well as a preparation method and an application thereof. The master batch is prepared by polypropylene and pulverized fodder with the proportion by weight of 100:30-45; the pulverized fodder is prepared by the following components according to parts by weight of: 11-30 parts of laminal filter, 1-3 parts of nano filter and 0.1-0.3 parts of polypropylene nucleating agent; the laminal filter is white mica or sericite. The preparation method of the master batch used for preparing high heat-resisting polypropylene plastic comprises the following steps: mixing the laminal filter and the nano filter; dissolving the nucleating agent by acetone and then evenly spraying into the mixed filter; mixing evenly and drying; mixing the dried pulverized fodder with the polypropylene fusion to prepare the master batch used for preparing high heat-resisting polypropylene plastic. The application of the master batch used for preparing high heat-resisting polypropylene plastic is as follows: 5-10 parts by weight of master batch are shattered, and are then extruded with 50-100 parts of polypropylene fusion to prepare high heat-resisting polypropylene plastic. The invention improves the heat resistance of polypropylene by the synergy of each component, and has wide market prospect.

Description

technical field [0001] The invention relates to a masterbatch for preparing high heat-resistant polypropylene plastic, a preparation method and application thereof, and belongs to the technical field of plastic processing. Background technique [0002] Compared with polyethylene, polypropylene (PP) is a plastic variety with great potential for application and development among the existing polyolefin plastic materials. It is light in weight, high in tensile and bending strength and modulus, good in comprehensive performance, cheap and easy to obtain, and easy to process. After modification, it has now replaced engineering plastics in many applications. Therefore, it has become one of the largest and most widely used plastic varieties in the world today. [0003] With the expansion and deepening of market applications, the performance requirements for polypropylene are also getting higher and higher. Among them, the heat-resistant temperature of polypropylene is increased ...
