Problems solved by technology

[0003] Domestic researches on marine coatings have been reported successively in recent years, such as the capsaicin antifouling primer of the China Ocean Second Institute. The amount is too large, making the net very thick, which is not conducive to the operation of the cage

example 1

[0018] Example 1: 5g of 50% pure tea saponin, 0.5g of 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethanol and 0.5g of 1-(6-chloro-3-pyridyl- After N-nitroimidazolidine)-2-ethylamine is fully ground together, it is added to 10 liters of phenolic resin paint primer and stirred for 1 hour, and after 3 days, it is stirred for the second time at high speed for 1 hour to make all the Ingredients are well mixed. Take a net cage made of nylon netting with a perimeter of 30m and a depth of 6m, and then use a paint brush to coat the mixed paint on the net body three times. The net body is naturally dried after 5 days, and is directly put into seawater to cultivate seafood for use. After the net cage is used for one year, the control rate of barnacles is above 96%, and the control rate of algae and shellfish is above 95%.

example 2

[0019] Example 2: 3.5g of 60% pure tea saponin, 0.7g of 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethanol and 0.7g of 1-(6-chloro-3-pyridyl -N-Nitroimidazolidine)-2-Ethylamine is fully ground together, added to 10 liters of phenolic resin paint base paint and fully stirred for 2 hours, placed for 2 days and then carried out the second high-speed stirring for 1 hour, so that all Ingredients are well mixed. Take a cage made of high-density polyethylene netting with a perimeter of 60m and a depth of 10m, and then use a paint brush to paint the mixed paint on the net body three times. After the net body is blown dry with a fan, it is directly put into the seawater to cultivate marine organisms. After the net cage is used for one year, the control rate of barnacles is above 98%, and the control rate of algae and shellfish is above 99%.

example 3

[0020] Example 3: 10 g of 30% pure tea saponin, 0.2 g of 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethanol and 0.2 g of 1-(6-chloro-3-pyridyl -N-Nitroimidazolidine)-2-Ethylamine are fully ground together, added to 10 liters of polyurethane paint base paint and stirred for 2 hours, after 1.5 days, the second high-speed stirring is carried out for 1 hour to make all the ingredients Mix well. Take a cage made of high-density polyethylene netting with a perimeter of 60m and a depth of 10m, and then use a paint brush to paint the mixed paint on the net body three times. After the net body is blown dry with a fan, it is directly put into the seawater to cultivate marine organisms. After the net cage is used for one year, the control rate of barnacles is above 95%, and the control rate of algae and shellfish is above 97%.

Abstract

The invention discloses sea deep water live box anti-soil paint. Its main component is plant extractive tea saponin. Its formula component is 100-1000mg 30-70% purity tea saponin per 1L base coating. The base coating can be any one of phenol resin paint, silicone adhesive, polyurethane paint. Auxiliary agent is 1,1-bi-(4- chlorphenyl)-2,2,2-ethapon and 1-(6-chlorine-3-pyridyl-N-nitro ous meter azole alkyl)-2-ethyl amine. It includes the following steps: high speed stirring for tea saponin and auxiliary agent and base coating; laying 1-3 days; second high speed stirring; coating on mesh body; and drying. The formed anti-soil paint is high efficiency, asepsis, low pollution, and low cost. And its prevention and cure rate for barnacle, algae, and seashell is more than 75%. The mash body is increased weight by 10% after coating. Thus this is not influence on its pliability. And it can repeatedly be used after cleaning.

Description

technical field [0001] The invention belongs to the technical field of marine deep-water cage culture, and relates to an antifouling paint for marine deep-water cages and its preparation and use methods. Background technique [0002] So far, many countries have reported that the method of coating anti-pollution paint on the cages is used to prevent the cages from being attached by filamentous algae or other organisms. Generally, the cages can be kept without cleaning for more than two months. For example, the World Wide Fund for Nature conducted a non-polluting primer experiment on ships in the waters of eastern Germany, and the results showed that there are 6 primers that have good effects and have been sold in some countries. Port of Sutton in the UK uses Irgarol 1051 compound as an algicide, and Germany uses TPT as an antifouling agent, and the antifouling effect is good. For example, Japan uses organotin compounds to carry out the anti-fouling test of cages in KITAURA B...
