Problems solved by technology

[0003] Spray-free products with metallic effects are generally realized by adding metallic effect pigments, but the orientation and accumulation of metallic pigments in the polymer matrix are prone to some surface problems, such as PA products with metallic luster are prone to leaving marks and welding marks on the surface , this type of product has a single structure and needs to be supplemented by special shape design and processing, but the problem of weld lines still exists and the cost is high

Abstract

The invention discloses a spray-free polyamide compound with metallic luster. The spray-free polyamide compound is prepared from the following raw materials in parts by weight: 100 parts of polyamide resin, 4-20 parts of acrylonitrile-styrol copolymer, 0.2-2 parts of metallic pigment, 2-10 parts of compatilizer, 0-25 parts of filler, 0.2-6 parts of flexibilizer, 0.2-2 parts of dispersing auxiliary and 0.2-2 parts of processing agent. According to the invention, the acrylonitrile-styrol copolymer used as a modifier and the polyamide resin are compounded as a matrix resin of the compound, and meanwhile, the other raw material components are adjusted and the compatilizer, the dispersing auxiliary and the flexibilizer at a specific ratio are supplemented, so that the processing performance of the polyamide compound and the mechanical property and appearance effect of the formed polyamide compound are optimized.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a spray-free polyamide composition with metallic luster and a preparation method thereof. Background technique [0002] As one of the widely used engineering plastics, polyamides (PA) have excellent comprehensive properties, such as good mechanical properties, chemical resistance and heat resistance, etc., but at the same time, polyamide resins also have low surface hardness and are easy to Not enough scratches etc. Through modification such as alloying or strengthening, etc., the performance of polyamide resin can be improved, so that it can meet different service conditions and expand the application field of polyamide. Acrylonitrile-styrene copolymer (acrylonitrile-styrene copolymer referred to as AS) has the advantages of transparency, chemical corrosion resistance, high modulus, and good processing fluidity. However, the impact performance of AS resin is poor, which limits ...
