Abstract

The invention discloses a high-fluidity black masterbatch for PA engineering plastics. The high-fluidity black masterbatch comprises the following components by weight: 29.5-50% of polyolefin resin, 5-20% of maleic anhydride grafted polyolefin, 20-50% of carbon black, 5-20% of nigrosine, 5-20% of nanometer silicon carbide, 5-15% of a rheological agent and 0.5-2% of a silane coupling agent. The invention also discloses a preparation method of the high-fluidity black masterbatch for PA engineering plastics. The high-black masterbatch can effectively improve the flowability of PA plastic and thedispersity of pigment; and therefore, the blackness, glossiness and wear resistance of the surface of a product are improved, the problem of floating fibers on the surface of reinforced nylon is improved, and the problems that existing black masterbatch is hard to meet higher requirements on the processability and surface of high-filling nylon engineering plastics and the like are solved. The preparation method is simple in process and low in cost.

Description

Technical field: [0001] The invention relates to the technical field of polymer materials, in particular to a high-flow black masterbatch for PA engineering plastics and a preparation method thereof. Background technique: [0002] As a widely used engineering plastic, PA has excellent performance, and its performance can be further improved after modification such as filling, reinforcement, toughening, and flame retardancy. It is widely used in automobiles, electronics, packaging, machinery, furniture, Building materials, sports and leisure products, daily necessities, toys and other industries. The coloring of modified nylon materials is an indispensable part in the processing of nylon products, and the coloring of nylon products is mainly black. [0003] At present, the black masterbatches used for nylon coloring are mainly general-purpose black masterbatches, which are obtained by melt extrusion of polyolefin and carbon black. When general-purpose black masterbatches ar...
