Problems solved by technology

However, due to the addition of silicon dioxide and silicone powder, the density and blackness of high-gloss black nylon are respectively affected.
In addition, compared with conventional nylon materials, transparent nylon materials are expensive, which makes them encounter greater resistance in the promotion and application of high-gloss black materials in automobiles and in the process of domestic marketization

Embodiment 11

[0072] The high-brightness black composite nylon material of Example 3 is used to make a sample plate, and the performance test is carried out. The results are: the blackness value is 24, the appearance has no pitting, and the linear wear resistance is 88%. It can be shown that the high-gloss black composite nylon material provided by the present invention can be suitable for preparing vehicle exterior parts with high requirements on appearance and wear resistance.

Abstract

The invention discloses a high-brightness black composite nylon material and a preparation method thereof. The high-brightness black composite nylon material is prepared from the following raw materials in parts by weight: 65-90 parts of nylon 6, 10-35 parts of nylon 56, 0.1-1 part of a functional nucleating agent, 0.15-0.6 part of carbon black and 0.4-1 part of an auxiliary agent, the functional nucleating agent is a polyamide-amine dendrimer grafted carboxylated carbon nano tube. The high-brightness black composite nylon material prepared by the invention has the advantages of low cost, good appearance and scratch resistance, meets the performance requirements of good appearance and scratch resistance when the high-brightness black composite nylon material is applied to automobile exterior trimming, and meanwhile, compared with a high-brightness black material which takes special nylon as a matrix in the market at present, the high-brightness black composite nylon material has the advantages of low cost, good appearance and scratch resistance. The obvious price advantage is realized.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-brightness black composite nylon material and a preparation method and application thereof. Background technique [0002] As we all know, the quality of the car is reduced by half, and the fuel consumption is also reduced by nearly half. Therefore, with the increasing demand for environmental protection and energy saving, the lightweight of automobiles, that is, reducing the curb weight of automobiles as much as possible on the premise of ensuring the strength and safety performance of automobiles has become the main theme of global automobile development. Therefore, in recent years, the proportion of plastic parts in auto parts has continued to expand, and a large number of plastic parts have been used for exterior parts. At present, parts with a high-gloss black appearance similar to piano black are more and more recognized by consumers, and the exterior parts...
