Abstract

The invention provides a drag-reducing anti-fouling paint free of any copper antifouling agent and a preparation method thereof. The drag-reducing anti-fouling paint free of any copper antifouling agent uses silane polyacrylate resin with a degradable main chain as a main base material and a rosin derivative as an auxiliary base material; an antifouling agent having high antifouling activity to hard shell fouling organisms and an antifouling agent having high antifouling activity to botanical and microbial fouling organisms are compounded and used as the antifouling agent of the paint; composite zinc oxide obtained by mixing of zinc oxide with different particle sizes is used for adjusting the dissolving speed of a paint film; a variety of colors are obtained in virtue of usage of filling materials like talcum powder, iron oxide red, iron oxide black, iron oxide yellow, carbon black, toluidine red, phthalocyanine blue, phthalocyanine green and titanium dioxide and pigments; and the particle sizes of the used anti-fouling agents, filling materials and coloring pigments are all not more than 30 [mu]m. A paint film formed after drying of the paint has a smooth surface and excellent anti-fouling and drag-reducing performance. The invention further provides the preparation method for the drag-reducing anti-fouling paint. The preparation process is practical and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a drag-reducing antifouling coating without copper antifouling agent and a preparation method thereof. Background technique [0002] Due to its high strength and light weight, aluminum alloy is often used as the main material of small ships, yachts and water equipment. Since ships and underwater equipment serve in the marine environment all year round, the problem of marine fouling adhesion and growth often occurs. Marine fouling not only increases the weight of ships and equipment in the water, but also changes the streamlined structure of the hull and increases the sailing resistance of the hull. [0003] Aluminum alloy ships operating in the marine environment used antifouling paints containing organotin compounds in the early days. With the increasingly stringent environmental protection regulations of various countries, the International Maritime Organization has banned th...
