Problems solved by technology

For example, when aquatic organisms attach to the surface of aquaculture equipment, they block the mesh of the aquaculture equipment, causing a large number of fish and shrimp to suffocate and die; aquatic organisms attach to the surface of ships, underwater pipelines, drilling equipment and other equipment, and as they grow, they will gradually Penetrates into the interior of the coating, destroys the coating, and eventually causes these devices to corrode
[0003] In the past few decades, antifouling coatings containing organotins have been widely used, but because these substances are stable and accumulate in water, very small concentrations can cause some organisms to deform, affecting human health and ecological security

Embodiment 1

[0043] The material for inhibiting biological adhesion is prepared from polypropylene, fluorine-treated acidic antibacterial agent, potassium sorbate, salt, and polyglycerin fatty acid ester. The amount of polypropylene is 880g, the amount of fluorine-treated acid bacteriostatic agent is 40g, the amount of potassium sorbate is 20g, the amount of salt powder is 20g, and the amount of polyglycerin fatty acid ester powder is 40g.

[0044] The specific preparation steps of the material for inhibiting biological adhesion are as follows:

[0045] 1) Dry all materials at 60°C;

[0046] 2) Stir the dried polypropylene, fluorine-treated acidic antibacterial agent, potassium sorbate, salt and polyglycerol fatty acid ester;

[0047] 3) Extrude through a twin-screw granulator, and then cut it with a granulator to obtain granules of suitable size. The obtained granules were dried in an oven, and the temperature was set at 60°C;

[0048]4) The dried particles are extruded by a single-scr...

Embodiment 2

[0050] The material for inhibiting biological adhesion is prepared from polypropylene, fluorine-treated acidic antibacterial agent, potassium sorbate, salt, and polyglycerin fatty acid ester. The amount of polypropylene is 860g, the amount of fluorine-treated acid bacteriostatic agent is 20g, the amount of potassium sorbate is 60g, the amount of salt powder is 20g, and the amount of polyglycerin fatty acid ester powder is 40g.

[0051] The preparation method of the material for inhibiting biological adhesion is the same as in Example 1.

Embodiment 3

[0053] The material for inhibiting biological adhesion is prepared from polypropylene, fluorine-treated acidic antibacterial agent, potassium sorbate, salt, and polyglycerin fatty acid ester.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a material for inhibiting biological adhesion and a preparation method thereof. Background technique [0002] With the increase of people's water activities, the adverse consequences of biofouling in some lakes have also attracted people's attention. Accumulation and fouling of undesired aquatic organisms attached to any equipment such as aquaculture equipment, ship hulls or seawater circulation systems. For example, when aquatic organisms attach to the surface of aquaculture equipment, they block the mesh of the aquaculture equipment, causing a large number of fish and shrimp to suffocate and die; aquatic organisms attach to the surface of ships, underwater pipelines, drilling equipment and other equipment, and as they grow, they will gradually Penetrates into the interior of the coating, destroys the coating and eventually causes these devices to corrode. [0003] In the past few...
