The invention relates to a preparation method of a super-hydrophobic composite coating based on magnetically-induced fluorinated graphene, which comprises the following steps: loading magnetic nanoparticles among fluorinated graphene sheets subjected to low-temperature ultrasonic dispersion by adopting a thermal solvent method to obtain a magnetic nanoparticle-fluorinated graphene composite material; coating the surface of a base material with a coating containing the magnetic nanoparticle-fluorinated graphene composite material, and then applying a directional magnetic field with a certain magnetic field intensity on the coating base material, so that the magnetic nanoparticle-fluorinated graphene composite material is directionally moved to the surface of the coating; the surface of the super-hydrophobic composite coating is provided with a microcosmic rough structure, and the super-hydrophobic composite coating has the characteristic of low surface energy. According to the preparation method, the dispersity of the fluorinated graphene in an organic resin matrix is improved, and the preparation process is simple, environmentally friendly, free of pollution and low in cost and can be used for large-scale production; according to the coating prepared by the preparation method, the corrosion resistance of the coating can be enhanced, multiple functions of hydrophobicity, corrosion prevention, antifouling and the like can be integrated, and the requirements of different application scenes are met.

The utility model relates to the technical field of plastics processing especially is a kind of plastic powder colouring biaxial colour mixing device, including plastic powder colouring biaxial colour mixing device main part, in the utility model, by designing a kind of plastic powder colouring biaxial colour mixing device, utilize the design of first spiral roller and second spiral roller biaxial spiral roller, so that plastic particles and colouring powder can be fully stirred and mixed, compared with the mixing effect of traditional single-shaft colour mixer, it is better, more uniform, production efficiency is also higher, the design of electric telescopic link controls the design of unloading, so that unloading operation is very convenient, and can be controlled by adjusting the moving range of moving plate to unloading speed, meets different production needs, the setting of dust collector, effectively collected the dust generated in the process of unloading, avoids dust pollution, improves working environment, protects the health of operator, the setting of dust collecting box also facilitates the centralized processing of dust, greatly improves the quality and efficiency of plastic powder colouring.
