Another aspect of the present invention provides a kind of preparation method of polyamide compoiste material and is somebody's turn to do, and the preparation method includes following step
Suddenly：
Each component materials are weighed respectively according to the composition and its content contained by above-mentioned polyamide compoiste material；
By the polyamide, the antioxidant, the grinding assistant modifier, the lubricant, the anti-glass emergence on the surface agent and
Mixed material is obtained after the compatilizer mixed processing；
In the main feed hopper that the mixed material is put into double screw extruder, the reinforcing agent is put into described pair of spiral shell
In the side spout of bar extruder, granulated through melting extrusion.
In the polyamide compoiste material that the present invention is provided, reinforcing agent increases the mechanical strength of polyamide compoiste material, grinding aid
Modifying agent improves its surface gloss, and antioxidant improves the ability that the heat resistanceheat resistant in its process is decomposed, and lubricant improves material
Between mobility, anti-glass emergence on the surface agent further prevents glass emergence on the surface, and compatilizer improves the toughness of polyamide compoiste material, should
By synergy between the composition and content of polyamide compoiste material, polyamide compoiste material is set to have high fluidity poor, high
The advantage of glossiness, and its good mechanical performance, glass are not easy exposed, can be widely applied to household electrical appliances accessory, electric match somebody with somebody
