Embodiment Construction

[0040] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. For the experimental methods without specific conditions indicated in the following examples, the conventional conditions or the conditions suggested by the manufacturer are usually followed.

[0041] Concrete preparation method is as follows:

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

Abstract

The invention discloses a polyamide composite material with high performance and high flow. The raw material composition includes polyamide resin, inorganic filler and calcium ricinoleate. The present invention also provides a method for preparing the high-performance and high-fluidity polyamide composite material, comprising: uniformly mixing all raw materials except inorganic fillers, and then feeding them into a twin-screw extruder from a main feeding hopper, Then, the inorganic filler is added into the twin-screw extruder from the side feeding hopper, extruded by the twin-screw extruder, and then water-cooled, pelletized and dried to obtain the high-performance and high-fluidity polyamide composite material. The present invention utilizes inorganic fillers to reinforce polyamide, and simultaneously utilizes calcium ricinoleate to improve the fluidity of the material, thereby greatly increasing the fluidity of the material and improving the glossiness of the surface of injection molded parts 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 and 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 water absorption results in the reduction of some mechanical properties and dimensional instability, causing various problems in the use of parts, so it needs to be passed Modification is used 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, it is obvious that such materials do not meet customer requirements. [0003] At present, the problem of fluidity of materials is ma...
