Problems solved by technology

However, PA and PC are two thermodynamically incompatible materials. The mechanical properties of the material obtained by direct blending are very poor and cannot be used. Due to the poor compatibility of the two, it is impossible to obtain the appearance of piano black.

Abstract

The invention relates to a high-gloss piano black polyamide (PA) / polycarbonate (PC) alloy resin composition and a preparation method thereof. The PA / PC alloy resin composition is prepared from the following components in parts by weight: 60-90 parts of PA resin, 10-40 parts of PC resin, 1-5 parts of a compatibilizer, 0.3-2.0 parts of black toner and 0.1-1.5 parts of an antioxidant. The preparationmethod of the high-gloss piano black PA / PC alloy resin composition comprises the following steps that the components in parts by weight are weighed and mixed evenly, thus a premix is obtained, the premix is added into a double-screw extruder to be subjected to melt extrusion, cooling granulation is conducted, and thus an objective product is obtained. The obtained PA / PC alloy resin has the high-gloss piano black appearance and meanwhile also combines the excellent toughness and dimensional stability of PC as well as the excellent abrasion resistance and chemical resistance of PA.

Description

technical field [0001] The invention relates to an alloy resin composition and a preparation method thereof, in particular to a high-gloss piano black PA / PC alloy resin composition and a preparation method thereof. Background technique [0002] In recent years, more and more high-gloss piano black effects have been used in auto parts, including automotive exterior parts (grille, pillar panels) and interior parts (navigation panels, gear panels). Using high-gloss paint-free piano black plastic is a low-cost and environmentally friendly way. However, because automotive interior parts have high requirements on the scratch resistance of materials, general piano black materials, such as piano black PC / ABS alloy, PC, PMMA / ABS alloy, etc., are difficult to meet the requirements. Piano black PA can meet the harsh scratch resistance requirements of the interior. However, because PA materials contain amide groups, this group is easy to absorb water, resulting in larger parts, and the...
