Problems solved by technology

[0004] The main defect of the above-mentioned method is: when high-gloss aluminum powder, copper-gold powder, pearl powder, etc. are blended with thermoplastic resins, the inorganic rigid pigments are not uniformly dispersed in the plastic matrix, and the bonding force with the plastic matrix interface is relatively weakened, especially Agglomeration occurs at the weld line
It not only reduces the mechanical properties of the product, but also affects the metal flash effect

Abstract

The invention discloses a device and method for manufacturing metal flashing plastic through ultrasonic treatment. The device comprises an extrusion die. An extrusion die cavity and a discharge outlet are arranged in the extrusion die. A supporting frame is arranged on one side of the extrusion die, and a temperature sensor is arranged on the other side of the extrusion die. An ultrasonic vibration control device composed of an ultrasonic generator, an amplitude-change pole and a transducer is installed on the supporting frame. One end of the transducer is connected with the ultrasonic generator, and the other end of the transducer is connected with one end of the amplitude-change pole. The other end of the amplitude-change pole is inserted into the extrusion die cavity in the extrusion die. The amplitude-change pole can make direct contact with blending plastic in the extrusion die and can be used for performing ultrasonic treatment on the blending plastic. The temperature sensor can detect the temperature of the blending plastic in the extrusion die, and is connected with a temperature controller. By means of the device and method, the mobility of mixtures of metal powder and plastic is improved; the processing temperature is reduced; the mechanical and high-temperature destructive power of an extrusion process is reduced; protection on the color effect is enhanced; the mechanical properties of materials are improved.

Description

technical field [0001] The invention relates to a device and method for ultrasonic treatment of plastics with metallic glitter effects, and belongs to the innovative technology of ultrasonic treatment for devices and methods for preparation of plastics with metallic glitter effects. Background technique [0002] At present, the manufacture of plastic products with aesthetic appearance has attracted more and more attention, because consumers' aesthetic perception of product appearance is becoming stronger and stronger. High-gloss aluminum powder, copper gold powder, pearl powder, fluorescent powder, luminous powder, reflective powder, etc., have been widely used in industrial fields. However, the main application is in coatings, accounting for about 85%, ink applications account for about 9%, plastic applications account for about 4%, and other applications account for about 2%. The composite of high-gloss aluminum powder and thermoplastic resin is a typical composite mater...
