[0051] 1. Preparation of mixed olefin grafted microspheres:

[0052] Mixed olefin grafted microspheres A

[0053] It is a copolymer microsphere of maleic anhydride, n-butene and isobutene, prepared by copolymerization of maleic anhydride, n-butene and isobutene in the presence of nitrogen, azobisisobutyronitrile (AIBN) initiator and organic solvent Mixed olefin graft copolymer microspheres A; the ratio of n-butene and isobutene is 1:1.

[0054] The weight ratio of mixed carbon four and maleic anhydride is 3:1.

[0055] The concentration of maleic anhydride in the organic solvent isoamyl acetate is 20wt%;

[0056] Initiator consumption is 1% of maleic anhydride weight;

[0057] The copolymerization reaction temperature is 80° C.; the copolymerization reaction pressure is 1 MPa; the copolymerization reaction time is 6 hours.

[0058] The particle size range of the microspheres is 5-8 microns.

Abstract

The invention discloses a mixed olefin grafted microsphere reinforced flame-retardant nylon 6 composition and a preparation method thereof. The nylon 6 composition is prepared by blending the following raw materials in parts by weight: 100 parts of nylon 6, 1-10 parts of polyethylene glycol; and 1-20 parts of mixed olefin grafted microspheres. The preparation method comprises the following steps: melting and blending the components according to the dosage to obtain the nylon 6 composition. According to the invention, the dispersity of glass fibers, flame retardants and other materials and polyolefin matrix affinity fillers can be greatly improved. Therefore, the dispersion of the flame-retardant material and the glass fiber in the polyolefin can be effectively enhanced, and the mechanical property and the flame-retardant effect of the material are improved.

Description

technical field [0001] The invention relates to the technical field of nylon, and more specifically relates to a mixed olefin grafted microsphere reinforced flame-retardant nylon 6 composition and a preparation method. Background technique [0002] 3D technology was born in the late 1990s. It is based on digital models and is a high-tech manufacturing technology based on material accumulation. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After being connected to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. [0003] 3D three-dimensional printing technology uses powdered metal or plastic and other bondable materials. It integrates mechanical engineering, CAD, reverse public technology, layered manufacturing technology, numerical control technology,...
