Abstract

The invention discloses a method for manufacturing a magnesium alloy colorless transparent film and a product with the same. The method includes the following steps: providing a magnesium alloy product, and finishing the product surface; degreasing the finished magnesium alloy product in an alkalescent degreasant and removing surface grease; carrying out surface conditioning on the degreased magnesium alloy product in strong aqueous alkali; carrying out brushed treatment on the surface-conditioned magnesium alloy product, cleaning the surface, removing surface dust, and showing metal texture of the product; dip-coating the brushed magnesium alloy product in aqueous solution of polyvinylpyrrolidone with the mass fraction of 0.5-2%, generating the colorless transparent film on the product surface, taking out the film and then drying and warming the film by the fire. The product with is the one obtained after being processed with the method. Therefore, metal texture of the brushed magnesium alloy workpiece can be shown, and the requirement for corrosion resistance is also met.

Description

【Technical field】 [0001] The invention relates to a method for making a film and a product thereof, in particular to a method for making a colorless and transparent film of a magnesium alloy and a product thereof. 【Background technique】 [0002] Because magnesium alloy material is a light structural material, the quality is 2 / 3 of aluminum and 1 / 4 of steel. Compared with steel, aluminum, plastic and other engineering materials, magnesium alloy has good strength and rigidity, and good electromagnetic shielding performance , non-magnetic; good shock absorption; non-toxic, recyclable; excellent machinability, high die-casting productivity, small size shrinkage, and has excellent low temperature performance and high thermal conductivity and is widely used. [0003] The traditional surface decoration of magnesium alloys is generally done by spraying paint, and the metallic luster on the surface of magnesium alloy products is difficult to show. The wire drawing process can make t...
