Aluminum plate surface spraying process capable of preventing paint from falling off

Abstract

The invention relates to the technical field of production and processing of aluminum plates, in particular to an aluminum plate surface spraying process capable of preventing paint from falling off. The problems that in the prior art, the paint face of the surface of an existing aluminum plate is poor in corrosion resistance, so that the paint face falls off, the existing aluminum plate is not suitable for being used for a long time, the aluminum plate after paint falling off is not attractive enough, the aluminum plate is troublesome to replace, and unnecessary economic expenditure can be caused are solved. The aluminum plate surface spraying process capable of preventing paint from falling off comprises the steps of film pasting and punching on the aluminum plate. According to the aluminum plate surface spraying process capable of preventing paint from falling off, mixed spraying of an ED1000 epoxy primer is carried out, the ED1000 epoxy primer is a solvent type anti-corrosion paint, the ED1000 epoxy primer is suitable for coating various metal surfaces, the adhesive force is high, and it is guaranteed that a coating does not fall off; and the corrosion resistance of the surface of the aluminum plate is improved through the ED1000 epoxy primer, the situation that a finish paint falls off due to corrosion is avoided, and therefore the long-time use standard is met, the attractiveness of the surface of the aluminum plate is guaranteed, the problem that the aluminum plate is replaced after paint falling off and the problem that the attractiveness of a filter plate is reduced are solved, and unnecessary economic expenditure is avoided.

Description

technical field

[0001] The invention relates to the technical field of aluminum plate production and processing, in particular to an aluminum plate surface spraying process for preventing paint falling off. Background technique

[0002] Aluminum and aluminum alloys are currently one of the most economically applicable materials that are widely used. Since 1956, the world's aluminum output has surpassed that of copper, and it has always ranked first in non-ferrous metals. The current production and consumption of aluminum (calculated by ton) is second only to steel, and has become the second largest metal used by human beings; moreover, aluminum resources are very abundant. According to preliminary calculations, the mineral reserves of aluminum account for more than 8% of the earth's crustal constituents. , Aluminum plate refers to a rectangular plate processed by rolling aluminum ingots, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, m...
