Problems solved by technology

[0002] The fouling problem of marine organisms has always restricted people's development and utilization of marine resources. The attachment of various marine organisms will increase the ship's navigation resistance and fuel consumption. The metabolites of marine organisms will corrode the ship and increase the ship's life. Maintenance costs will reduce the voyage rate of ships, and marine organisms will also block various pipelines, valves and meshes of breeding cages on the seabed, causing economic losses that are difficult to estimate
However, the continuous release of cuprous oxide and other substances into seawater will lead to the accumulation of heavy metal ions in harbors and marine organisms, causing environmental pollution and endangering human health and safety.

Embodiment 1

[0026] Add 1 part of synthetic capsaicin into a four-neck flask, add 200mL of sterilized deionized water, make the liquid surface submerge the stirring paddle, place the four-necked flask on a constant temperature water bath for heating and stirring, and set the initial temperature of the constant temperature water bath The temperature is 85°C, and the stirring rod speed is set to 300r / min. After half an hour, the stirring paddle speed is reduced, and 2 parts of diatomite are weighed and slowly added to the four-necked flask, and the speed is increased to 450r / min to make the diatomite evenly Disperse in the capsaicin suspension, remove the water bath after 10 minutes, reduce the speed to 300r / min, and at the same time pass cooling water to the surface of the four-necked flask until the liquid in the four-necked flask drops to room temperature, so that the capsaicin crystals are precipitated and deposited On the diatomite, reduce the speed after 30 minutes, add acrylic acid sel...

Abstract

The invention provides an acrylic resin embedding capsaicin antifouling agent and its preparation method and application. The embedding capsaicin antifouling agent includes capsaicin, porous powder and acrylic self-polishing resin; the capsaicin is loaded on A carrier is formed on the porous powder; the acrylic self-polishing resin covers the carrier; the mass ratio of the antifouling agent is capsaicin: porous powder: acrylic self-polishing resin=1:2~4:0.05~0.15 . On the one hand, the present invention can realize the surface protection of capsaicin, prevent its continuous release and dispersion in the air during the manufacturing process of antifouling paint and the application process of antifouling paint, causing skin irritation of production and painting workers and allergies and other health hazards, prevent the continuous release of capsaicin in the air and reduce the antifouling effect.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling paint and underwater paint. Specifically, it is an acrylic resin embedding treatment capsaicin antifouling agent and its preparation method and application. Background technique [0002] The fouling problem of marine organisms has always restricted people's development and utilization of marine resources. The attachment of various marine organisms will increase the ship's navigation resistance and fuel consumption. The metabolites of marine organisms will corrode the ship and increase the ship's life. Maintenance costs will reduce the voyage rate of ships, and marine organisms will also block various pipelines, valves and meshes of culture cages on the seabed, causing economic losses that are difficult to estimate. 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 f...
