Problems solved by technology

If the painted film is removed and the surface treatment is done again, it is time-consuming, labor-intensive and material-intensive
Removing the paint with the paint remover method, not to mention the cost, will cause pollution to the surrounding environment, and will also bring harm to the operator, and the operation is inconvenient; it is not safe to remove the paint with the burning method, and it will a

Embodiment Construction

[0020] Now in conjunction with embodiment the present invention will be further described:

[0021] Formula (mass%)

[0022]

[0023] When preparing, fill container 1 with polyvinyl butyral, add isopropanol (99%) and stir evenly; fill container 2 with phosphoric acid (85%), add industrial ethanol (95%) and stir evenly; Then mix the solutions in containers 1 and 2 and add other substances, and stir evenly.

[0024] Coating:

[0025] Step 1: Use cotton yarn dipped in ethyl acetate or solvent gasoline to wipe the surface of the original paint film to remove visible grease. Generally wipe 2 times.

[0026] Step 2: Dilute the paint to application viscosity with denatured alcohol. Use brushing, and adjust the construction viscosity to (Tu-4) 18-25 seconds (Tu-4 refers to the paint viscosity measured with a Tu-4 viscometer, see GB / T1723-93 Paint Viscosity Measurement Method, the same below). Apply by spraying. The construction viscosity is adjusted to (Tu-4) for 13-18 second...

Abstract

The invention relates to transition paint for an easy-lifting paint film surface. The transition paint is characterized by comprising the following material components in percentage by weight: 8.5% of polyvinyl butyral, 5.0% of alkali type zinc yellow, 1.5% of talcum powder, 52.2% of isopropanol, 4.8% of chromium phosphate, 14.7% of methyl iso-butyl ketone, 10.8% of industrial alcohol, 1.2% of phosphoric acid and 1.3% of water. The coating method is used for coating the transition paint on the surface of the easy-lifting paint film surface, so that the transition paint is cured to form a shielding paint film of strong solvent resistant paint (for example nitryl finish paint, acrylic finish paint and acrylic polyurethane finish paint). And strong solvent paint is re-coated on the shielding paint film, so that a lifting phenomenon does not appear.

Description

technical field [0001] The invention relates to a transition paint for the surface of an easy-to-bite primer film and a preparation and coating method, which is suitable for coating the surface of general equipment and facilities. Background technique [0002] When repainting the paint film on the surface of equipment and facilities, if the original paint film will be bitten by strong solvent paint (such as nitro topcoat, acrylic topcoat), the existing technology either removes the paint on the surface of equipment and facilities. paint film, recoat with a solvent-resistant primer followed by a strong solvent paint; or improve the situation with a fast-drying topcoat with a high pigment-to-base ratio. See P341 of "Coating Technology" edited by Zhang Xuemin. [0003] If a quick-drying topcoat with a high pigment-to-base ratio is used to solve the problem of undercutting, it will face unsatisfactory problems such as the performance and color of the quick-drying topcoat. If t...
