Abstract

The invention discloses a spraying method for an aluminum alloy profile frame used for an automobile. The spraying method is characterized by comprising the following steps that (1) an aluminum alloy profile frame blank is manufactured; (2) the surface of the aluminum alloy profile frame is subjected to deoiling; (3) moisture on the surface of the aluminum alloy profile frame is removed by hot wind; (4) atomized liquid is sprayed onto the surface of the aluminum alloy profile frame; and (5) electrostatic powder is sprayed. According to the spraying method, after the aluminum alloy profile frame blank is manufactured, the surface of the aluminum alloy profile frame is subjected to deoiling, and then the electrostatic powder is sprayed; the thickness of a powder coating is controlled reasonably according to the corrosion resistance quality requirements and the surface roughness of a coated piece, and the energy consumption, the waste water draining amount and waste residue discharge amount are reduced; meanwhile, the problem that the electrical conductivity of weld joints of parts is poor, and consequently the coating quality is influenced is solved, so that a light abrasion-resistant aluminum-based composite which is completely suitable for automobile parts is obtained; and the friction coefficient of the composite is 0.35-0.45, and the abrasion amount is smaller than 0.3 g / MJ.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a spraying method for an aluminum alloy profile frame for an automobile. Background technique [0002] Due to the continuous improvement of users' requirements for automotive coatings, especially the general requirement for the salt spray resistance of hot-rolled plate parts coatings to reach more than 504h, the coating process of spraying or dipping paint used in the past has made the product coating The quality cannot meet the anti-corrosion requirements, so the use of powder coating has become the development trend of hot-rolled plate parts coating. [0003] Injection technology was first developed based on the purpose of energy saving, low consumption, and low cost. It is a new technology for rapid solidification of materials near-formation. Its basic principle is to atomize molten metal or alloy in an inert atmosphere to form a droplet jet stream. , directly ...
