Self-swim paint dressing technique

Abstract

The invention discloses an oil paint padding method. It uses the method of adopting automatic deposition to form a paint film on the surface of mental material by chemical reaction. The method comprises the following steps: degreasing, water cleaning, acid cleaning, hot water cleaning, pure water cleaning, oil paint self-padding, and water cleaning, post treating and dry treating and so on. Wherein the self-oil paint is prepared by AUTOPHORETIC866 type resin, AUTOPHORETIC300Sarter type resin and ion-free water by the ratio of AUTOPHORETIC866 type resin: AUTOPHORETIC300Sarter type resin: ion-free water=113:50:837.

Description

(1) Technical field [0001] The invention relates to a paint coating method. Specifically, it is a water-based coating method that uses automatic precipitation and forms a layer of paint film on the surface of metal materials through chemical reactions. (2) Background technology [0002] As we all know, there are mainly two traditional paint coating methods, one is spraying and the other is brushing. Regardless of spraying or brushing, the surface of the workpiece needs to be degreased and derusted, surface adjusted and phosphated, and the workpiece can be dried before the paint can be applied to the workpiece with a spray gun or paint brush. Since there is a large amount of phosphoric acid in the phosphating treatment of the workpiece, when the iron reacts with the phosphating solution, the iron will be dissolved, causing a large amount of phosphoric acid and iron ions to be discharged during cleaning, thereby polluting the environment. And because the workpiece needs to b...

Problems solved by technology

Since there is a large amount of phosphoric acid in the phosphating treatment of the workpiece, when the iron reacts with the phosphating solution, the iron will be dissolved, causing a large amount of phosphoric acid and iron ions to be discharged during cleaning, thereby polluting the environment

And because the workpiece needs to be dried before painting, the energy consumption is high and the production cost is high.

In addition, using the above two coating methods, it is necessary to add auxiliary materials such as diluent, drier, curing agent, moisture-proof agent, defoamer, plasticizer, stabilizer and leveling agent to the paint, and these auxiliary materials The materials are all solvents, and these solvents will generate a lot of harmful gases during operation

These harmful gases will not only pollute the environment, but also endanger the health of operators

On the other hand, when the spraying method is used for paint coating, the paint splashes, and the utilization rate is not high, usually only about 50%, which makes the production cost higher
