Abstract
The invention provides PA (polyamide) resin composition used for an NMT (nano molding technology) and having an LDS (laser direct structuring) function. The PA resin composition used for the NMT is mainly prepared from raw materials in parts by mass as follows: 30-90 parts of PA resin, 10-40 parts of glass fibers, 3-25 parts of inorganic whiskers, 3-10 parts of an LDS auxiliary, 0.3-5 parts of a stabilizer, 3-15 parts of a toughening agent and 0.5-3 parts of a lubricant, wherein PA resin is PA66 resin and / or PA6 resin. The glass fibers are partially replaced with inorganic whiskers, so that the sensitivity of an electromagnetic wave signal is improved, and the laser etching precision and accuracy of a material surface are improved; the defects that ordinary LDS special materials have poor binding force with metals, the molding shrinkage is large, the acid and alkali resistance is poor and LDS cannot be performed are overcome, the PA resin composition has strong binding force with metals, the binding strength is higher than 180 kgf / cm<2>, and the laser etching and chemical plating effects are good; besides, the requirements of LDS and NMT are met; material has excellent mechanical performance, good heat resistance and excellent molding machining performance.
Description
technical field [0001] The invention relates to the technical field of polyester compositions, in particular to a polyamide resin composition for NMT with LDS function. Background technique [0002] With the development of science and technology and the improvement of living standards, many mainstream high-end products in the communication field such as mobile phones are increasingly made of metal materials, such as portable video player shells, audio player shells, display cabinets, car computer panels, and mobile communication products. High-end products in fields such as casings, projector casings, front and back covers of laptops, etc. are all made of metal. NMT (NanoMolding Technology) technology is a nano-molding technology that combines metal and plastic nanotechnology. Although the industrialization of NMT technology has realized the integrated molding of metal-plastic materials, it simplifies the design and manufacturing process of product mechanism components, imp...
