A special nylon material used in an automobile intake manifold and a processing method thereof relate to a special nylon material used in an automobile intake manifold, and aims to overcome the disadvantages of the prior binary-system nylon material including poor processing liquidity and rough surface and internal wall. The special nylon material consists of 30 to 70 wt percent of nylon, 5 to 35wt percent of short fiber, 5 to 35 wt percent of thermotropic liquor polyamide and 0.1 to 5 wt percent of processing agent, wherein the nylon is aliphatic polyamide; the short fiber is glass fiber GFor carbon fiber CF; the thermotropic liquor polyamide is main chain type aromatic polyamide with the fusion scope ranging between 180 and 300 DEG C; and the processing agent is one or a plurality of lubricant, heat stabilizer, nucleater, antioxidant and colorant. According to the processing method, all components of the nylon material are fully mixed and are extruded through a double screw extruder to carry out granulation, thereby obtaining the special nylon material after drying. The special nylon material has the advantages of smooth surface, excellent processing liquidity and thermal stability, high mechanical property and low vibration noise, etc.

This invention discloses a complex material contg. granular packing and thermal liquid polymer (TCLP), mfg. method and use thereof. Said complex material is composed of (by wt. portion): 30-85 nylon 6, 5-70 granular packing and 1-20 TLCP, where-in, granular packing being hollow glass micro-balls (GB), solid glass micro-balls, SiO2 or CaCO3 with granularity of 1-100 mum; TLCP being main-chain type aromatic copolymer with its molten-range of 190-360 deg.C. Said complex material is made by molen-blending method. This product has excellent flow-ability and dimension-stability. It has potential superiority in mfg. thin-wall plastic products of fine-structure plastic products.
