The antifouling paint is mainly composed of five parts, namely film-forming resin, antifouling agent, pigment and filler, solvent and auxiliary agent, wherein the antifouling agent is a main disinfectant playing a poisoning role on the attached marine organisms, the resin is a carrier for adhering and dispersing the antifouling agent and is a main film-forming substance, and the antifouling period of the antifouling paint can reach 5 years. However, as the growth of marine organisms in the pacific ocean area was investigated, low concentrations (20 ugL) were noted -1 ) The TBT solution of (a) can lead to oyster growth malformations and defects, and also to feminization of other marine organisms. When the tributyltin content reaches 1ppm, shells in the sea grow to be deformed, especially for residents living near seasides of shipyards, so that the damage affects not only marine organisms but also the normal life of human beings, therefore, the resin and the antifouling agent are main components determining the antifouling performance of the antifouling paint, and the novel waterproof and antifouling coating resin is provided for overcoming the technical defects.

2) Diluting 80% hydrazine hydrate to a certain concentration, putting the diluted hydrazine hydrate solution into a constant-pressure funnel, adjusting the dropping speed to enable the hydrazine hydrate solution to be dropped into the dissolved copper acetate solution by about 5s one drop, accelerating stirring, and keeping the reaction temperature constant;
3) After the reaction is finished, continuously stirring for 30min at constant temperature to ensure that the reaction is completely carried out, bottling the product, sealing, and observing the stability condition;
further, the nano Cu is prepared by reducing copper acetate solution by using hydrazine hydrate as a reducing agent 2 O sol, the reaction formula of which is as follows: 4Cu (OOCH) 3 ) 2 +N 2 H 4 +2H 2 O→Cu 2 O+N 2 +8CH 3 COOH
4) Then placing the prepared cuprous oxide sol for one day, and then placing the cuprous oxide sol into a conical flask for heating and stirring to keep the temperature constant;
furthermore, when the cuprous oxide content exceeds 2%, the hybrid resin system becomes cloudy, the system is not transparent, and the viscosity of the system begins to decrease, so that the addition amount of the fat-based coating agent for coating the cuprous oxide sol cannot be too large, and too much fat-based coating agent can cause the acrylic acid monomers and the cuprous oxide sol to react with each other. Therefore, the upper limit of the copper content in the hybrid resin is 2% when the cuprous oxide is contained;
5) Dripping fat coating agent into the system, slowly adding the fat coating agent, violently stirring to ensure smooth reaction and constant temperature, continuously stirring for 30min at constant temperature after the reaction to ensure complete coating reaction, and finally generating the fat coating agent to coat Cu 2 O sol;

wherein, the decomposition temperature of Azobisisobutyronitrile (AIBN) is 68 ℃, the half-life period is 0.1h (101 ℃), the half-life period is 1.0h (82 ℃), the consumed initiator can be supplemented in time by adopting the method of slowly dripping the initiator and the monomer into the reactor at the same time, the dripping time is generally longer, the monomer conversion rate can be increased, and the conversion rate is improved;
the mechanism by which AIBN initiates free radical polymerization is as follows:
initiation of AIBN:
radical polymerization of acrylic monomers:
acrylic acid and fat coating agent coated Cu 2 Polymerization of O System:
