Problems solved by technology

[0002] During ship navigation, seawater, sewage and petrochemical pipeline transportation, fouling organisms will quickly multiply on the solid surface and reproduce on the surface, thus forming biofouling. In order to reduce fouling, it is necessary to apply anti-corrosion and drag-reducing coatings. At present Most of the anti-corrosion and drag-reducing coatings used are solvent-based coatings, which not only waste energy, but also pollute the environment, harm human health, and have potential safety hazards. Therefore, environmentally friendly coatings such as solvent-free, water-based, and powder have become a substitute for solvent-based coatings. trend

Abstract

The invention provides a ceramic antifouling material and a preparation method thereof. The ceramic antifouling material comprises the components of, by weight, 9-20 parts of Al2O3, 50-90 parts of Al,29-30 parts of AlN and 30-50 parts of ZrO2. The invention further discloses a preparation method of the ceramic antifouling material. The preparation method comprises the steps that a proper amount of Al2O3, Al, AlN, ZrO2 and a sintering aid are weighed and taken and then put into a nylon ball mill tank, the mass ratio of corundum grinding balls to the raw materials is 5:1, and the ball milling medium is absolute ethyl alcohol; and after ball milling is carried out for 48 hours, drying, grinding, sieving, granulating, forming (200MPa) and sintering are carried out. After the ceramic antifouling material is coated on the wall surface of conveying pipelines for seawater, sewage and petrochemical engineering, the conveying efficiency can be remarkably increased, and the adhesion area of thebiological compound dirt can be reduced.

Description

technical field [0001] The invention relates to material technology, in particular to a ceramic antifouling material and a preparation method thereof. Background technique [0002] In ship navigation and transportation of seawater, sewage and petrochemical pipelines, fouling organisms will quickly multiply on the solid surface and multiply on the surface, thereby forming biofouling. In order to reduce fouling, it is necessary to apply anti-corrosion and drag-reducing coatings. Most of the anti-corrosion and drag-reducing coatings used are solvent-based coatings, which not only waste energy, but also pollute the environment, harm human health, and have potential safety hazards. Therefore, solvent-free, water-based, powder and other environmentally friendly coatings have become a substitute for solvent-based coatings. trend. [0003] Due to its high strength and chemical stability, ceramic materials are widely used in various harsh environments such as wear resistance, corros...
