Abstract
The utility model discloses a corrosion-resistant double-layer coating structure for steel surface, including basement steel, basement steel upper berth is equipped with first coating, first coating upper berth is equipped with the second coating, first coating is polysilazane resin, the second coating is epoxy aramid coating, basement steel surface forms the roughened layer through handling. The device is connected by curing the upper and lower coatings formed by the reaction of polysilazane resin and epoxy resin in the epoxy aramid coating, and compared with the conventional coating, the device has the advantages that the connection structure is firmer by the adhesion between the middle layers; the roughened layer is arranged on the surface of the base steel material, so that the connection strength of the first coating can be increased.
Description
Technical Field
The utility model relates to a metal surface treatment technical field, concretely relates to corrosion-resistant double-layer coating structure for steel surface.
Background
Along with the wide application of steel products, the corrosion prevention of steel structures is continuously paid attention, according to incomplete statistics of developed countries, the economic loss caused by corrosion accounts for about 1% -4% of the total value of national economy every year, the corroded steel products account for 20% of the total production amount of China every year, and 30% of steel equipment and tools are scrapped due to corrosion. The economic loss caused by corrosion is more than 300 million yuan per year, and accounts for 4 percent of the total value of national production. Especially in high-temperature and humid working environments, the corrosion of steel is more serious. The corrosion of steel not only causes economic loss, but also brings potential safety hazard to the safety of the structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a corrosion-resistant double-deck coating structure for steel surface to solve the problem that mentions in the background art. In order to achieve the above object, the utility model provides a following technical scheme: the corrosion-resistant double-layer coating structure for the steel surface comprises base steel, wherein a first coating is laid on the base steel, a second coating is laid on the first coating, the first coating is polysilazane resin, the second coating is an epoxy aramid coating, and a roughened layer is formed on the surface of the base steel through treatment.
Preferably, the polysilazane resin of the first coating layer is connected by forming upper and lower coating layers by reaction with the epoxy resin in the epoxy aramid coating layer and curing.
Preferably, the upper surface of the first coating is provided with a reticular structure seam.
Preferably, the first coating layer is connected to the base steel material by a curing agent.
The utility model discloses a technological effect and advantage: the device is connected by curing the upper and lower coatings formed by the reaction of polysilazane resin and epoxy resin in the epoxy aramid coating, and compared with the conventional coating, the connection structure between the middle layers is firmer through adhesive force; the roughened layer is arranged on the surface of the base steel material, so that the connection strength of the first coating can be increased.
