Abstract

The invention provides a non-toxic biological anti-fouling resistance reducing composite coating, which sequentially comprises a priming paint coating, a luminous powder coating and a protective coating. The protective coating is positioned on a surface layer, the priming paint coating is positioned on a bottom layer, the luminous powder coating is positioned between the protective coating and the priming paint coating, and the surface of the non-toxic biological anti-fouling resistance reducing composite coating is provided with a micron-sized pit structure. The invention further provides a preparation method for the composite coating and an anti-fouling resistance reducing treatment method for the surface of a base material. According to the non-toxic biological anti-fouling resistance reducing composite coating prepared by the preparation method, as luminous powder is capable of illuminating environments, attachment of marine organisms is reduced by means of the photoinhibition effect. On one hand, the luminous powder is non-toxic and radiation-free, and negative effects on the environments are decreased. On the other hand, as the surface of the composite coating is provided with the micron-sized pit structure, the flow field of a near wall can be changed, resistance reduction is realized and coupled with an anti-fouling method, and anti-fouling and resistance reducing functions are realized.

Description

technical field [0001] The invention relates to a biological antifouling and drag reducing coating, a preparation method of the biological antifouling and drag reducing coating, and a surface antifouling and drag reducing treatment method, more specifically, to a non-toxic biological antifouling containing luminous powder Drag-reducing composite coating, preparation method of the non-toxic biological anti-fouling and drag-reducing composite coating containing luminous powder, and antifouling of substrate surface by using the non-toxic biological anti-fouling and drag-reducing composite coating containing luminous powder Method of drag reduction treatment. Background technique [0002] Under water, on the bottom surface of various substrates, the attachment, growth and reproduction of various organic life forms (such as microorganisms, Ulva, barnacles, etc.) have brought many disadvantages, and this phenomenon is collectively called biofouling. For example, biofouling in the...
