Description
Technical field
The invention belongs to technical field of coatings, and in particular to it is a kind of can linging colored paint in wet on wet, the dry one pack system squirted
And preparation method thereof.
Background technique
Spray robot is called paint-spray robot, is that can carry out auto spray painting or spray the industrial robot of other coating,
It is mainly made of robot body, computer and corresponding control system.Paint-spray robot generally uses hydraulic-driven, has
The features such as quick action, explosion-proof performance are good can realize teaching by teach-by-doing teaching or point registration, be widely used in vapour
The techniques such as vehicle, instrument, electric appliance, enamel production division.Spray robot can be by being arranged spray parameters, to improve spraying
Quality and materials'use rate have many advantages, such as easily operated and maintenance.During automotive lacquer, the brushing of middle linging colored paint is must
An indispensable link, middle linging colored paint are also referred to as base coat, and feature is that viscosity is slightly larger, and paint film is thicker, and filling capacity is good,
The thickness of finishing coat can be reduced and increase the richness of finishing coat, be mainly used for filling and leading up the fine pore and sand of priming paint or putty surface
The polishing trace of paper, keeps coating surface more flat and smooth, while the adhesive force of priming paint or putty and finishing coat also can be improved.Middle painting
Base coat surfacing, smooth, grinability is good, corrosion resistance and has excellent water-resistance, and when paint film after being sprayed on electrophoresis layer, assigns
Paint film has good resistance to hitting property of stone, fillibility, uvioresistant penetrability and flexibility, and the appearance and performance to the entire paint film of automobile rise
Vital effect, and face linging colored paint is mainly to be to confer to the color appearance of paint film after being sprayed on middle linging colored paint.
Usually said wet on wet spraying process refers to that middle Base coating paint layer is spaced 5min after spray coating, and surface of the paint film is not yet
Surface drying, in the state of wet, spray-coating surface Base coating paint layer；And it is dry squirt spraying process refer in Base coating paint layer spraying
After reaching surface drying by way of low-temperature bake after painting, then spray-coating surface Base coating paint layer.Current middle linging colored paint is wet in progress
When touching wet spray, two different paints will appear situations such as stinging paint and bleeding, and carry out dry when squirting spraying, aqueous overcoating background color
It paints and is difficult wetting on another water paint after being sprayed on surface drying.
104109428 A of Chinese patent application CN discloses one kind can the wet on wet white floating coating of 3C1B and its preparation side
Method, the white floating coating include following component: polyester resin, titanium white, bentonite slurry, dispersing agent, thermosetting acrylic resin, ammonia
Base resin, occlusive polyurethane, acrylate leveling agent A, acrylate leveling agent B, CAB solution, epoxy resin liquid, PMA, diformazan
Benzene, n-butanol and butyl acetate are in the system of oiliness, on normal production line, can reach surface drying in 5min, from
And a possibility that realizing 3C1B, it is not required to apply paint line in addition, is not required to individually toast, production efficiency can be improved, reduce to apply and dress up
This, but the white floating coating can not be sprayed under process conditions in dry squirt, and will cause the use of product to a certain extent
Limitation, influences production effect.Currently, leading to floating coating very since the rate of volatilization of the water in water-based system is slower than solvent very much
Difficulty reaches surface drying in 5min on normal production line, to increase the difficulty of the wet on wet possibility of water paint, it is therefore desirable to
There is provided it is a kind of can not only have been carried out in normal production line 5min it is wet on wet spraying but also can be in the case where stopping line, middle linging colored paint
Reach can still carry out after surface drying it is dry squirt spraying and final effect can achieve substantially it is consistent can wet on wet, the dry list squirted
Linging colored paint in component.
