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, capsaicin is directly mixed into the paint, and the inventor's related experimental research shows that, on the one hand, during the production and coating application of capsaicin antifouling paint, capsaicin is easy to volatilize into the air, which will cause production and construction personnel Respiratory tract and skin produce allergic reactions. On the other hand, the release rate of capsaicin in the cured coating is also difficult to effectively control, which sometimes causes defects such as blistering, peeling, and falling off of the antifouling coating.

Embodiment 1

[0027] 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 rotating speed after 30 minutes, add a rosin...

Abstract

The present invention provides a rosin buried treatment of capsules and its preparation methods and applications, which include the pollutants include capsules, porous powder and rosin resin;; The carrier of the rosin resin is covered; the composition of the pollutant -proof agent is capsules: porous powder: rosin resin = 1: 2 ~ 4: 0.05 ~ 0.15.The present invention uses the solubility of rosin in the seawater and the good compatibility of organic solvents and resins, and the mosin is used for embedding of capsules. On the one handDuring the production of the production process and the painting application of polluting anti -coating, it continues to be dispersed in the air, causing health hazards such as the skin stimulation and allergies of production and coating workers, and preventing the effect of continuously releasing and reducing the effect of anti -dirty protection in the air.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling paint and underwater paint. In particular, it relates to a rosin-embedded capsaicin antifouling agent and a preparation method and application thereof. 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 foulin...
