Problems solved by technology

[0004] 1. Most of the solvent-based interface water uses water-insoluble organic solvents. When sprayed on the surface of water-based industrial coatings, shrinkage cavities will occur
[0005] 2. Solvent-based interface water is incompatible with water-based industrial coating topcoat, which will cause loss of gloss
[0006] 3. Solvent-based interface water dries slowly. When it is used to repair the interface of water-based industrial paint topcoat, it is easy to be stained with dust due to too long drying time, and it cannot be transported quickly

preparation example Construction

[0049] A possible preparation process of the interface water provided by the present invention is: under stirring condition, mix 5-10 parts of the first solvent, 30-50 parts of the second solvent, 20-40 parts of the third solvent, 5-10 parts of the fourth solvent , 6-10 parts of thermoplastic acrylic resin and 0.1-2 parts of surfactant are put into the container in turn, continue to stir until they are fully mixed and dissolved, then filter with 200-mesh silk cloth, and the filtrate is the interface water that meets the requirements.

[0050] A possible application process of the interface water used for repairing the water-based industrial paint topcoat in the present invention is: the water-based industrial paint topcoat is sprayed on the place that needs to be repaired; after 3-5min, the interface water is sprayed on the interface periphery and Spray the paint on the entire repaired surface until the paint surface appears glossy; after 3-5 minutes, a uniform and bright paint...

Abstract

The invention discloses an interface water for repairing water-based industrial paint topcoats. The interface water comprises the following components in parts by weight: 5-10 parts of the first solvent; 30-50 parts of the second solvent; 20-40 parts The third solvent; 5-10 parts of the fourth solvent; 6-10 parts of thermoplastic acrylic resin; 0.1-2 parts of surfactant; wherein, the boiling point of the first solvent is not lower than 190°C and can be mixed with water in any proportion The boiling point of the second solvent is 160°C-189°C, which is miscible with water in any proportion; the boiling point of the third solvent is 110°C-159°C, and the solubility in water is 1.0%-15.0%; The boiling point of the fourth solvent is 60°C-109°C, and the solubility in water is 5.0%-100.0%. The interface water can eliminate shrinkage cavity, whitening, loss of gloss and other problems in the repair process, and the repaired paint surface is uniform and bright without repair traces, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of coatings. More specifically, it relates to an interface water for water-based industrial paint topcoat repair and its application. Background technique [0002] During the construction of industrial coating topcoats, there are often situations where rework is required. For example, partial paint film blistering, shrinkage, sagging, etc., missing spray, and paint film damage during assembly; at this time, rework is required. There are usually two rework methods, one is overall rework and repainting, and the other is repairing after partial grinding. Partial repair has become a more acceptable method because it saves a lot of labor and material costs. However, when repairing, partial spraying will inevitably produce an interface, and the splashed paint mist will form a circle of dull interface around the repair. At this time, spray suitable interface water on the interface, which can dissolve the paint ...
