Abstract

The invention discloses an antistatic high-gloss polyketone material which comprises the following components in parts by weight: 100 parts of POK, 0.1-1 part of a single-walled carbon nanotube, 0.1-0.5 part of a main antioxidant, 0.1-0.5 part of an auxiliary antioxidant, 0.1-0.5 part of a light stabilizer and 0.1-0.5 part of a lubricant. The carbon nanotube CNT is added into the polyketone POK material, so that the modified polyketone material has the characteristics of highlight black and antistatic property. The invention also discloses a preparation method of the antistatic high-gloss polyketone material. The prepared antistatic high-gloss polyketone material is subjected to injection molding in a rapid cooling and rapid heating steam mold temperature controller control mode to obtain a part with a high-gloss black surface, and the antistatic high-gloss polyketone material can be applied to high-gloss parts in places easy to touch, such as automotive trim instrument panel decorative strips, center console decorative rings, keys, door panel decorative strips, and the antistatic high-gloss polyketone material can aslo applied the electronic and electric appliance high-gloss shells, such as television decorative frames, printer cover plates.

Description

technical field [0001] The invention relates to the field of polyketone materials, in particular to an antistatic high-gloss polyketone material and a preparation method. Background technique [0002] Polyketone material is referred to as POK or PK material. It has relatively high crystallinity, relatively regular structure, excellent wear resistance and scratch resistance, excellent chemical resistance, certain barrier and flame retardancy, good impact toughness, and easy processing. It is an ideal material for preparing automotive interior and exterior trims. In recent years, high-gloss materials have developed rapidly. The injection-molded parts of high-gloss materials do not need to be painted, which is energy-saving and environmentally friendly. At the same time, they are used in automotive interior parts and have an aesthetic function. At present, most of the high-gloss materials for automotive interiors are made of PC / ABS, PMMA and other materials. The surface has in...
