Embodiment Construction

[0040] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. In the following examples, the experimental methods without specific conditions are usually in accordance with conventional conditions, or in accordance with the conditions suggested by the manufacturer.

[0041] The specific preparation method is as follows:

[0042] Add nylon, calcium ricinoleate, toughening agent, black masterbatch, antioxidant and lubricant into the stirring pot, mix evenly for 7min, then add it to the twin-screw extruder from the main feeding hopper, and remove the glass fiber from the side. The feed hopper is added to the twin screw extruder. After being extruded by a twin-screw extruder at a specific temperature, water-cooled, pelletized and dried to obtain a polyamide composite material with high performa...

Abstract

The invention discloses a high-performance high-flow polyamide composite material. The high-performance high-flow polyamide composite material comprises the following raw materials: polyamide resin, an inorganic filler, and calcium ricinoleate. The invention also provides a preparation method for the high-performance high-flow polyamide composite material. The preparation method comprises the following steps: uniformly mixing all the raw materials except the inorganic filler, then feeding the formed mixture into a twin-screw extruder from a main feed hopper, then adding the inorganic filler into the twin-screw extruder from a side feed hopper, carrying out extrusion via the twin-screw extruder, and then performing water cooling, pelletizing and drying to obtain the high-performance high-flow polyamide composite material. According to the invention, the inorganic filler is utilized to enhance polyamide, and calcium ricinoleate is used for improving the fluidity of the material, so the fluidity of the material is greatly increased and the gloss of the surface of an injection molded part is improved under the premise of ensuring mechanical properties.

Description

technical field [0001] The invention relates to the technical field of polyamide composite materials, in particular to a high-performance high-flow polyamide composite material and a preparation method thereof. Background technique [0002] As an engineering plastic, polyamide has been widely used in automobiles, electronic appliances, etc., but its own water absorption results in the reduction of some mechanical properties and dimensional instability, which causes various problems in the use of parts, so it is necessary to pass Modification to maintain the stability of the material, and glass fiber reinforcement is the main way to solve this problem. However, due to the addition of glass fiber, the fluidity of the material is reduced, and the appearance of the part is prone to floating fibers. For parts with high surface gloss requirements, obviously such materials do not meet customer requirements. [0003] At present, the problem of material fluidity is mainly solved by...
