Example Embodiment

[0017] This embodiment provides a high-strength metal product. The metal product is coated with a protective layer. The chemical composition and mass percentage of the protective layer are as follows: silica: 12-14%, Zr: 2-4%, alumina: 2 —3%, Ta: 1-2%, Hf: 1.9-3.1%, cross-linking agent: 4-5%, acrylic adhesive: 1-2%, Al: 2-5%, Si: 2.1-3.5% , Styrene-butadiene-styrene block copolymer: 2.3-4.3%, rare earth: 3-4.5%, emulsifier: 2-2.5%, the balance is additives and fillers.

[0018] The filler is selected from a mixture of carbon black particles, polyethylene particles, acrylic particles and polyester particles.

[0019] The crosslinking agent is selected from one of isocyanate crosslinking agents, epoxy crosslinking agents or peroxide crosslinking agents. The emulsifier is composed of reactive emulsifier V-2 and anionic emulsifier A-6830.

[0020] A method for preparing high-strength metal products includes the following steps:

[0021] a. Prepare metal product blanks. Use shot blasting ...

Abstract

The invention discloses a high-strength metal product and a preparation method thereof, belonging to the technical field of metal products. The metal product is coated with a protective layer. The chemical composition and mass percentage of the protective layer are as follows: silicon dioxide: 12-14%, Zr: 2-4%, alumina: 2-3%, Ta: 1-2%, Hf: 1.9-3.1%, crosslinking agent: 4-5%, acrylate adhesive: 1-2%, Al: 2-5%, Si: 2.1-3.5%, styrene-butadiene-styrene block copolymer: 2.3-4.3%, rare earth: 3-4.5%, emulsifier: 2-2.5%, and the balance is auxiliary agents and fillers.

Description

technical field [0001] The invention relates to the technical field of metal products, in particular to a high-strength metal product and a preparation method thereof. Background technique [0002] With the progress of society and the development of science and technology, metal products are used more and more widely in various fields of industry, agriculture and people's life, and they also create more and more value for society. Although the existing metal products have a good appearance, their surface strength is relatively low. During daily use, the metal products themselves will wear out quickly, thereby reducing the service life. Contents of the invention [0003] The technical problem to be solved by the present invention is how to make metal products have stronger wear resistance so as to increase their service life. [0004] In order to solve the above technical problems, the present invention provides a high-strength metal product, the metal product is coated wi...
