Embodiment

[0051] 1. According to Example 1 in Table 1, add each component in turn and stir to form a mixed coating component A.

[0052] 2. According to Example 4 in Table 2, add each component in turn and stir to form the coating component B.

[0053] 3. According to Example 7 in Table 3, add each component in turn and stir to form a diluent.

[0054] 4. Fully mix Example 1 and Example 4 at a volume ratio of 1:1. Add 1 part of the mixed oil to 3 parts of Example 7 and stir evenly, put it into the metal zipper workpiece to be coated and soak for 10-30 seconds, take it out and let it dry naturally, then put it in a 120°C oven and bake for 30 minutes.

[0055] 5. Repeat steps 1-4 alternately according to the embodiment in Table 1, Table 2, and Table 3. The performance test conditions are shown in Table 4, and the test results are good, as shown in Table 5.

Abstract

The invention discloses a metal paint, and a preparation method and an application thereof. The metal paint is mainly composed of mixed components of a component A and a component B according to a volume ratio of 14:1. The component A comprises the components of, by weight: 40-60% of epoxy amino copolymer resin, 20-30% of amino resin, 5-10% of epoxy resin, 8-20% of an organic solvent, and 0.1-0.5% of a leveling agent. The component B comprises the components of, by weight: 30-50% of nitrocellulose, and 50-70% of an organic solvent. The metal paint provided by the invention has excellent chemical resistance and good enzyme washing resistance. The method for coating a metal workpiece by using the paint is simple and fast, and causes low pollution. An obtained paint film on the metal workpiece is smooth, and has high gloss and good resistance to enzyme solutions.

Description

technical field [0001] The invention relates to the field of metal coatings, in particular to a metal coating suitable for coating small metal workpieces and a preparation method and application thereof. Background technique [0002] In the prior art, there are three methods of painting zippers: one is production line spraying. Due to the special shape of zippers, when spraying on the production line, there are often problems such as uneven thickness of the surface paint film, lack of oil on parts, and easy scratches on the paint film. Moreover, the production efficiency of production line coating is relatively low; the second is rolling spraying. Although the rolling spraying technology has improved production efficiency, due to the surface gloss of the product, the surface of the paint film is not smooth enough, and the spraying effect is not satisfactory; the third is manual spraying. Manual spraying is not only efficient It is very low, and the coating film thickness of ...
