Embodiment Construction
[0032] Below in conjunction with embodiment the present invention is described in further detail.
[0033] Implementation Example 1
[0034] A method for producing a flame-retardant super-tough composite modified nylon masterbatch, the steps of which are as follows:
[0035] (1) Preparation of nylon toughening compatibilizer, weigh maleic anhydride MAH, vulcanizing agent DTBH, and grafting aid CB at 1.5:0.1:0.2, stir evenly at 65°C, and then add 20 parts of The diluent butanone, stirred evenly and cooled to normal temperature, is made into a mixed liquid, wherein the maleic anhydride MAH is commercially available, the vulcanizing agent double 2,5 DTBH is commercially available, and the grafting aid CB is commercially available styrene, caprolactam or monomaleic acid A kind of ester; according to the ratio of 85:15:15, the ethylene-octene copolymerized metallocene elastomer polymer POE, polypropylene PP, and the mixed solution are extruded and granulated with a twin-screw extr...
