The polyamide composite material comprises the following raw materials in percentage by weight: 40-70 percent of polyamide 6, 1-10 percent of low-fusion point polyamide, 1-5 percent of compatilizer, 0.2-5 percent of composite heat stabilizer, 0.5-5 percent of lubricant and 20-40 percent of reinforcement component. Meanwhile, the invention discloses a preparation method of the polyamide composite material for the vehicle induction manifold. The composite material has good heat-resistant performance and heat fusion performance and is especially suitable for preparing workpieces of vehicle induction manifolds; moreover, the preparation method is simple, adopts traditional equipment, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polyamide composite material for a vehicle intake manifold and a preparation method thereof. Background technique [0002] Polyamides are collectively referred to as nylon (Nylon), and the English name is Polyamide (referred to as PA). Polyamide is a kind of semi-crystalline high polymer, which has the characteristics of light weight, high mechanical strength and good electrical insulation performance, and also has good wear resistance, oil resistance, self-lubrication and corrosion resistance. ideal material. [0003] The long-term service temperature of nylon is closely related to the thermo-oxidative aging of the material. During melt processing and use, nylon is prone to generate free radicals under the action of heat and oxygen, and continuous degradation reactions occur. Oxygen oxidizes nylon and turns it yellow, producing a cross-linked structure and other oxidation b...
