Problems solved by technology

[0002] The problem of fouling of marine organisms has always restricted people's development and utilization of marine resources. The attachment and fouling of marine organisms will increase the resistance of ships to sail, increase fuel consumption, increase ship maintenance costs, and reduce the ship's voyage rate. cause huge economic losses
CN1810903A discloses a biological low surface energy antifouling coating for ships, which is composed of low surface energy resin, biological extract (capsaicin, chitin) microcapsules, nano-titanium dioxide, microporous silicon dioxide and solvent. The coating of this invention has Advantages such as self-cleaning property, corrosion resistance, high temperature resistance and weather resistance, but what use in this invention is biological extract (capsaicin, chitin) microcapsules, will first carry out single-layer wall building and then carry out double-layer in the preparation process. The wall is built in layers, and the preparation process is cumbersome

Abstract

The invention belongs to the technical fields of antifouling coatings and underwater coatings, and discloses a self-polishing antifouling coating excluding cuprous oxide and organic tin and a preparation method thereof. Problems that an existing antifouling coating is not environment-friendly, and the like, are solved. The coating provided by the invention is prepared from a film-forming substance, a capsaicin raw material, an environment-friendly antifouling agent, porous powder, a pigment, a filling material, an additive and a solvent. The preparation method comprises the following steps ofdispersing through multiple-time agitation. According to the antifouling coating provided by the invention, a compound antifouling agent is stored by utilizing the micron, the nanometer and a hole ofthe porous powder; afterwards, the porous powder and the compound antifouling agent are wrapped and isolated by utilizing silica and the compound antifouling agent; the irritation action, on production and construction personnel, of the compound antifouling agent can be decreased to some extent; the rate that capsaicin and the environment-friendly antifouling agent are released into seawater is effectively controlled; thus, the long-time and continuous favorable antifouling effect is more easily obtained; the self-polishing antifouling coating is safe and friendly to a marine environment. Thepreparation method provided by the invention is simple in process and practical and basic raw materials to which the preparation method relates can be all purchased on the market.

Description

technical field [0001] The invention belongs to the technical field of antifouling paint and underwater paint, and in particular relates to a self-polishing antifouling paint without cuprous oxide and organic tin and a preparation method thereof. Background technique [0002] The problem of fouling of marine organisms has always restricted people's development and utilization of marine resources. The attachment and fouling of marine organisms will increase the resistance of ships to sail, increase fuel consumption, increase ship maintenance costs, and reduce the ship's voyage rate. cause huge economic losses. In order to achieve the prevention and control of marine organisms, anti-fouling coatings are the only widely used and economical and efficient way to solve the problem of fouling. However, many antifouling coatings currently used contain releasable antifouling agents (such as cuprous oxide) that may cause seawater pollution and heavy metal enrichment, cause biological...
