Embodiment Construction

[0014] A method for preparing a metal-plastic composite material, characterized in that it comprises the steps of:

[0015] (1) Use a vacuum drying oven to treat PES65%~75%, PTFE15%~25%, LCP4%~8%, graphite 3%~5%, MoS 2 0.8% ~ 1% dry, using a vortex type high-efficiency mixer for 5 ~ 6 hours;

[0016] (2) Metal surface treatment: Alkaline cleaning and degreasing → water washing → pickling and rust removal → neutralization → water washing → surface adjustment → phosphating → water washing → drying → standby; this process can remove surface oxides, oil stains, and dust; and The steel plate after phosphating treatment can form an insoluble layer of phosphate protective film on its surface, which has good antirust ability and adhesion;

[0017] (3) Coarse the metal surface with injection-suction shot peening; the pressure is 0.4-0.6MPa, the hardness of cast steel shot is generally 40-50HRC, the shot-peening speed is 60m / s, and the shot-peening distance is controlled at 200-400mm ...

Abstract

The invention provides a preparation method for a metal-plastic composite material, which belongs to the field of material preparation. The preparation method is characterized by comprising the following steps: mixing and drying of raw materials; surface treatment; roughening; and compression molding of a sprayed metal matrix and plastic layer blended powder at high temperature. The prepared metal-plastic composite material has good binding performance. Through improvement of the preparation method, the metal-plastic composite material with good nucleating performance is obtained, the problem of untight pore structure of the material is effectively overcome, and the binding strength of the material is greatly improved; and the preparation method for the composite material is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a method for preparing a metal-plastic composite material. Background technique [0002] In recent years, with the rapid progress of science and technology, along with the increase of investment in research and development of materials science, researchers have found that compared with traditional single materials, polymer / metal composite materials have outstanding advantages such as high specific strength, high hardness, and wear resistance. Advantages, some even have excellent properties beyond the characteristics of metals and polymers. However, the poor bonding properties of metals and polymers has been hindering the application of polymer / metal composites. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a method for preparing a metal-plastic composite material. [0004] A method for preparing a metal-plastic comp...
