Problems solved by technology

In the nylon-copper composite material, since the copper is wrapped by nylon and does not contact with seawater, it is difficult to reach the critical exudation rate.
To achieve anti-biofouling, it is nec

preparation example Construction

[0029] In addition, if figure 1 As shown, the present invention also proposes a preparation method of an anti-biofouling nylon-copper composite material, which is used to prepare the above-mentioned anti-biofouling nylon-copper composite material, comprising the following steps:

[0030] Step 1: Place the powdered nylon and copper components in a drying oven for drying;

[0031] Step 2: Put the dried nylon and copper components and the coupling agent in the mass proportion: 0.5%-10% copper component, 0.1-1% coupling agent and 89%-99.4% nylon Take out after mixing evenly in a high-speed mixer to obtain nylon-copper composite powder;

[0032] Step 3: adding nylon-copper composite powder into the extruder, extruding after melt blending, and then passing through water cooling and pelletizing to form nylon-copper composite particles;

[0033] Step 4: Drying the nylon-copper composite particles and injecting them with an injection molding machine.

[0034] In this embodiment, the...

Embodiment 1

[0041] A nylon-copper composite material comprises the following components: copper oxide, with a mass fraction of 10%; a silane coupling agent, with a mass fraction of 1%; and the balance of nylon 6. Copper oxide is added in powder form with an average particle size of 100 mesh. The ingredients in the formula are dried, mixed uniformly, then extruded with a twin-screw extruder, granulated and then injection-molded to obtain a nylon-copper composite material. The strength of the prepared nylon-copper composite material is 65MPa, and it has been used in seawater for 2 years without marine biofouling.

Abstract

The invention provides a biofouling-proof nylon copper composite material and a preparation method thereof. The biofouling-proof nylon copper composite material comprises, in percent by mass, 0.5-10%of a copper component, 0.1-1% of a coupling agent and 89-99.4% of nylon. The biofouling-proof nylon copper composite material includes the copper component, coupling agent and nylon which are common,and has simple compositions, no toxic substances and no pollution to the environment; the content of the copper component in the material is low, so that the cost of the material is low; when the copper compound in the copper component is compared with metallic copper, the copper compound can be dissolved out in seawater easily, and a minimum seepage concentration of antifouling organisms can be ensured.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anti-biological fouling nylon-copper composite material and a preparation method thereof. Background technique [0002] The surface of ships, drilling platforms, harbor buildings and other underwater facilities in contact with seawater is prone to adhere to marine organisms and suffer from fouling by marine deposits. For ships, due to the attachment of marine organisms, the surface frictional resistance will be significantly increased, which will increase the fuel consumption of the ship and reduce the speed of the ship. In addition, the underwater sonar devices of ships, such as the outer surface of sonar dome, anechoic tile and acoustic baffle, and the acoustic window of the mine, will be damaged by accelerated corrosion due to the adhesion and growth of marine organisms, and the sensitivity, acoustics and so on will be damaged due to fouling. The char...
