Abstract

The invention relates to a preparation method of maleic anhydride graft polypropylene wax, which is characterized by comprising the following steps: heating and melting polypropylene wax in a kettle by using a heating system and a mixer of a reaction kettle; mixing a maleic anhydride graft monomer with the addition of 1.5 to 8.0 of polypropylene in percentage by weight by controlling the mixing rate from 120 r / min to 250 r / min at reaction temperature from 100 DEG C to 250 DEG C; adding an initiating agent with the addition of 1 / 30 to 1 / 10 of the adding quantity of maleic anhydride and a graft active agent with the addition of 1:3 to 2:1 of the weight of the maleic anhydride at reaction time from 0.5 hour to 10 hours, thereby completing the graft reaction of the maleic anhydride; and then cooling, pelleting or crushing maleic anhydride graft polypropylene wax so as to complete the preparing process of the maleic anhydride graft polypropylene wax. The invention also discloses a relative device. The preparation method of maleic anhydride graft polypropylene wax has the advantages of simple and reasonable technology, easy manufacture, low production cost, simplified product formula, and the like.

Description

technical field [0001] The invention relates to a production and preparation method of maleic anhydride grafted polypropylene wax and a related production and preparation device. Background technique [0002] Plastic products often need to add a variety of additives to achieve multiple functions during the processing process, but this often reduces the processing performance of the plastic and complicates the processing procedure. Therefore, the development of additives with multiple composite functions has become a research hotspot in the industry. By adding the functions of multiple additives to a "comprehensive additive", or combining multiple additives into a "composite package" with an appropriate ratio, the additives can achieve antioxidant, stability, Anti-aging and aging resistance are equal to one comprehensive performance, and it is very convenient to use. Therefore, it is the most popular variety in the market and has become a research hotspot for major foreign a...
