Problems solved by technology

Due to their good mechanical properties, metal materials are often used in the shipbuilding industry, but their corrosion resistance is limited, and the hull is easily corroded after a period of use; non-metallic materials are used in the shipbuilding industry, such as the commonly used material FRP , which has the advantages of light weight, especially suitable for high-performance ships and racing boats with limited weight, corrosion resistance and resistance to marine growth, more suitable for use in marine environments than traditional shipbuilding materials, good dielectric properties and microwave penetration , It is also suitable for military ships, with good impact toughness, the ship is not easy to be damaged by general collision and extrusion, and the appearance is more beautiful, and the maintenance cost is low, but the elastic modulus of FRP is low, the performance is unstable and easy to aging. Limits its use on ships
[0003] In order to combine the advantages of metal materials and non-metal materials, the adhesives used to bond metal materials and non-metal materials in the prior art tend to make the composite materials obtained after bonding not fastened, due to the linear expansion coefficient of the two materials It is easy to cause shedding or cracking when the temperature difference occurs

Abstract

The invention relates to a coating and a preparation method and application thereof. The coating is characterized by comprising the following raw materials in parts by weight: 10-11 parts of metal powder and glass fiber powder in total, and 6-10 parts of glue components. The part between a metal plate and a fiberglass plate is coated with a plurality of layers of coatings at different raw material ratios, is solidified and formed into a composite board with the coefficient of linear expansion gradually varying to fiberglass coefficient of linear expansion from metal coefficient of linear expansion, so that the metal plate and the fiberglass plate are bonded more firmly and are not easy to shed, and the composite board is endowed with both good mechanical property and good corrosion resistance and impact resistance.

Description

technical field [0001] The invention relates to a paint, a preparation method and an application thereof. Background technique [0002] Shipbuilding materials are generally divided into two categories: metallic materials and non-metallic materials. Due to their good mechanical properties, metal materials are often used in the shipbuilding industry, but their corrosion resistance is limited, and the hull is easily corroded after a period of use; non-metallic materials are used in the shipbuilding industry, such as the commonly used material FRP , which has the advantages of light weight, especially suitable for high-performance ships and racing boats with limited weight, corrosion resistance and resistance to marine growth, more suitable for use in marine environments than traditional shipbuilding materials, good dielectric properties and microwave penetration , It is also suitable for military ships, with good impact toughness, the ship is not easy to be damaged by general ...
