Embodiment 1
[0013] This embodiment is a method for processing single-component self-drying anti-corrosion enamel. The steps are: soak the paint residue with xylene or / and butanol solvent in which the paint residue accounts for 1 / 2 of the volume, filter the paint residue, and remove larger impurities , and then dehydrate the paint slag in a vacuum low temperature environment with a vacuum degree of 0.5-0.8MPa and a temperature of 60-80°C, and then add 566 alkyd resin at a ratio of 10% to 20%, and disperse at a ratio of 0.2-0.5%. Agent, wetting agent in the proportion of 0.1-0.3%, adding pigments as needed, and then grind the mixture to the required fineness, generally 30μm. Afterwards, add reactive groups at a ratio of 10 to 20%, modify the resin to improve its performance, add a leveling agent at a ratio of 0.1 to 0.5%, add a naphthenic acid drier at a ratio of 0.2 to 1%, and finally Use xylene: butanol: CAC (or ethylene glycol butyl ether or 150# aromatic hydrocarbon) = 8: 2: 1 to adjust...
Embodiment 2
[0025] This embodiment is a method for processing two-component self-drying enamel. The steps are: soak the paint residue with xylene or butanol solvent accounting for 1 / 2 of the paint residue weight, filter the paint residue, and then vacuum the residue at a vacuum of 0.5 to 0.8 Under the condition of MPa and temperature of 60-80℃, carry out vacuum low-temperature dehydration, then add 512 alkyd resin in the proportion of 50%, dispersant in the proportion of 0.2-0.5%, wetting agent in the proportion of 0.1-0.3%, and according to Pigments need to be added, grind the mixture to the required fineness, add defoamer at a ratio of 0.1-0.3%, leveling agent at a ratio of 0.1-0.5%, and accelerator at a ratio of 0.3-0.5% to increase cross-linking Density, to promote the reaction curing speed, add solvent to adjust to the required viscosity, and finally add curing agent N75 or 740, the weight ratio of curing agent to paint residue is 1:3~1:5.

Embodiment 3
[0038] This embodiment is a method for processing amino baking varnish. The steps are: soak the paint residue with xylene or butanol solvent accounting for 1 / 2 of the paint residue volume, filter the paint residue, and then vacuum the paint residue at a vacuum degree of 0.5 to 0.8 Carry out vacuum low-temperature dehydration at MPa and temperature of 60-80°C, then add 512 alkyd resin at a ratio of 40%, dispersant at a ratio of 0.2-0.5%, wetting agent at a ratio of 0.1-0.3%, and pigments , Add ethylene glycol butyl ether or CAC at a ratio of 5 to 10%, grind the mixture to the required fineness, and press 20％ Add A08-55 resin in proportion, leveling agent in proportion of 0.1-0.5%, defoamer in proportion of 0.1-0.3%, and finally adjust viscosity with xylene and butanol in proportion of 7 / 3 to make paint.
[0039] The indicators achieved by the paint are:
