Problems solved by technology

However, when the existing vitrification agent is used for vitrification treatment, it is necessary to adjust the vitrification agent to be acidic. After the treatment, the workpiece needs to be cleaned, which is cumbersome to operate. Coating will cause rust. Even after washing, the corrosion resistance of bare parts cannot be extended too much. For workpieces that are not as good as coating after vitrification treatment, they will be rusted and scrapped, which is not conducive to mass production. Reduce subsequent coating efficiency

Abstract

The invention provides a washing-free vitrification agent. The washing-free vitrification agent comprises the following components in percentage by mass: 5%-10% of silica sol, 5%-10% of alumina sol, 10%-30% of zirconium salt, 5%-10% of nitrate, and 40%-75% of water. According to the invention, the added zirconium salt is converted into zirconium dioxide as a main metal passivation layer; the nitrate is used for promoting the generation of a passivation film layer; and the silica sol and the alumina sol are compounded to form a covering layer which is attached to the surface of the metal passivation layer and fills gaps of the passivation layer, so that the metal passivation layer can be prevented from being too thick, and meanwhile, the corrosion resistance of the passivation layer can be better improved. The invention further discloses a use method of the washing-free vitrification agent. According to the use method, after the pH is adjusted through dilution, a workpiece is soaked or sprayed, washing is not needed, and simple operation, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of metal surface treatment agents, in particular to a water-free vitrifying agent and a use method thereof. Background technique [0002] When spraying steel-like metal workpieces, in order to improve the performance of the paint film, it is usually necessary to treat the metal surface before spraying. The existing metal surface treatment process includes ceramic treatment, which is to form a layer of ceramic film on the metal surface to increase the adhesion of paint and improve the corrosion resistance of the painted metal. However, when the existing vitrification agent is used for vitrification treatment, it is necessary to adjust the vitrification agent to be acidic. After the treatment, the workpiece needs to be cleaned, which is cumbersome to operate. Coating will cause rust. Even after washing, the corrosion resistance of bare parts cannot be extended too much. For workpieces that are not as good as coating af...
