Nanometer water-based paint with high antifouling performance, and preparation method and equipment thereof

Abstract

The invention discloses a nanometer water-based paint with high antifouling performance. The paint is prepared from the following components in parts by weight: 100 parts of a polyurethane-acrylic emulsion, 15-20 parts of rosin, 10-15 parts of nanometer silicon dioxide, 10-15 parts of nanometer titanium dioxide, 5-10 parts of xylene, 2-5 parts of butyl acetate, 10-15 parts of copper pyrithione, 0.5-1.0 part of a surfactant and 40-50 parts of deionized water. The invention further discloses a preparation method and preparation equipment of the nanometer water-based paint with high antifouling performance. According to key points in the invention, the components, the preparation method and the equipment of the high-antifouling nanometer water-based paint are improved at the same time, so theantifouling effect of the paint is improved, and the paint is non-toxic and environmentally friendly; and meanwhile, the equipment is used for feeding while stirring, so various processes and processing methods can be integrated in one piece of equipment. The paint provided by the invention has excellent hydrophobicity and rapid, balanced and continuous hydrophobicity migration, and presents goodantifouling performance; and a coating formed by the paint is high in strength and good in adhesive force.

Description

technical field [0001] The invention relates to the field of nano water-based paint, in particular to a high antifouling nano water-based paint, a preparation method and equipment. Background technique [0002] The nano antifouling paint in the prior art is composed of nano antifouling base material, paint base, poison, pigment, auxiliary agent and solvent. Asphalt, chlorinated rubber, acrylic resin and vinyl resin are generally used as nano-antifouling base materials and paint bases. The original poisons were compounds such as arsenic and mercury, which have been banned due to their high toxicity. At present, cuprous oxide, organotin compounds and their complexes are widely used. Auxiliaries include dispersants, anti-sedimentation agents and exudation regulators. Due to the toxicity of heavy metals and organotins, the International Marine Organization has completely banned the use of such antifouling coatings. The nanomaterials used have special properties such as surfa...

Problems solved by technology

However, it cannot realize the processing of various processes such as stirring while feeding, heating, and decompression according to the coating composition and preparation process.

[0005] In summary, there are some defects in the existing nano-water-based coatings, which cannot realize the material environmental protection, high-efficiency anti-fouling, and the anti-fouling effect is not good enough; at the same time, the dispersion equipment for preparing nano-water-based coatings cannot be fed while stirring during use, and at the same time realize Concentrate multiple processes and processing methods in one device to complete
