Abstract

The invention discloses a ceramic-imitated plastic composite material and a preparation method thereof, relates to a high molecular composite material, and provides the imitative ceramic plastic composite material which has the combined advantages of plastic and ceramic, is impact-resistant, easy to form and recover and has high surface glossiness and the preparation method thereof. The imitative ceramic plastic composite material comprises the following components: a plastic material, zinc oxide, a coupling agent, a lubricant, a weighing filler, a toughening agent and fiber. The preparation method comprises the following steps of: adding the zinc oxide and the weighing filler into a mixer; spraying the coupling agent; adding the lubricant, the toughening agent and the plastic material into the mixer to obtain mixed raw materials; throwing the obtained mixed raw materials into a double-screw extrusion granulator; performing melt extrusion to form wires; cooling; and granulating to obtain the imitative ceramic plastic composite material. If the fiber is available in the formula, the fiber is fed from a side feed port of the double-screw granulator during extrusion granulation.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a ceramic-like polymer composite material and a preparation method thereof. Background technique [0002] Ceramic products are deeply loved by people because of their natural, beautiful, durable, and low-cost characteristics, and can be seen everywhere in life. However, ceramics also have disadvantages such as high firing energy consumption, poor toughness and brittleness. It has become a trend to develop new materials with simple production process, easy recycling, and superior mechanical properties to replace existing ceramic materials. [0003] Because ceramics have the above advantages, people have long hoped to use plastics with better processing properties to imitate the appearance of ceramics. For example, adding a few percent of toner to the plastic material can adjust the appearance of the plastic material to various The appearance of ceramics, or the appearance of ceram...
