Embodiment

[0006] Example: An antifouling paint, magnesium complex is synthesized according to the molar ratio of specific acrylic resin and soy oil 5:1, feeding, the reaction temperature is controlled at about 70°C, and the heat preservation reaction is 1.5-3h, then the material can be unloaded, and the obtained Magnesium complex products: 360kg of magnesium complex, 45kg of zinc oxide, 48kg of iron red, 48kg of titanium dioxide, 75kg of talcum powder, 75kg of barite, 4kg of modified montmorillonite, 1kg of capsaicin. Each 330 liters of base and n-butanol, after stirring, add 360kg of magnesium complex and stir to dissolve, under stirring, add zinc oxide, iron red, titanium dioxide, talcum powder and barite in the order of formula dosage, after stirring for 10 minutes, Add modified montmorillonite, stir for 30 minutes, put all the materials into a sand mill and sand in the sand mill for 30 minutes, then add capsaicin and continue stirring for 10 minutes, then discharge to obtain an antif...

Abstract

The present invention relates to an antifouling paint which consists of 360kg of magnesium complex, 45 kg of zinc oxide, 48 kg of gulf red, 48kg of titanium white, 75kg of French chalk, 75kg of barite,4kg of modified turface and 1kg of capsaicin. Firstly, 330L of dimethyl and 330L of normal butanol are added in a reaction kettle; after the 360kg of magnesium complex is added with stirring to dissolve, the zinc oxide, the gulf red, the titanium white, the French chalk and the barite are added according to a sequence of compounding dosage; after stirring for 10 minutes, the modified turface is added; after stirring for 30 minutes, all materials are put in a sand mill for sand grinding for 30 minutes, and then the capsaicin is added, stirred continuously for 10 minutes and discharged, thereby achieving the antifouling paint. The present invention has the advantages of being difficult for marine organism to attach, driving the marine organism away from a coating surface to achieve high-efficient antifouling effect and having lasting and stable antifouling effect and innocuity.

Description

technical field [0001] The invention relates to an antifouling paint. Background technique [0002] Silicone resin self-polishing antifouling paint film is prone to cracks and dissolves too quickly. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defective, a kind of antifouling paint is provided. [0004] The technical solution of the present invention is: an antifouling coating, characterized in that: add xylene and n-butanol into the reaction kettle, add the magnesium complex under stirring and stir to dissolve, then add pigment, filler and dispersant in sequence under stirring , after mixing evenly, put it into a sand mill and carry out sand milling for 30 minutes, add capsaicin and continue sand milling for 10 minutes, discharge the material, and obtain the product. [0005] The invention has the following advantages: marine organisms are difficult to attach and are driven away from the surface of the coating to ...
