Description
Technical field
The present invention relates to apply paint field in automobile, and in particular in a kind of blade coating type based on thermoplastic acrylic resin
Apply car paint and preparation method thereof.
Background technique
The middle coating that applies is applied to a kind of coating between priming paint and finishing coat, and aqueous middle painting coating has with the development of science and technology
Significant progress, if CN201510580874.3 discloses a kind of aqueous primer surfacer, in percentage by weight, during this is aqueous
The japanning polyurethane-acrylate aqueous dispersion modified including 50~60% epoxy-silicone resin, 17~23% antirust face
Material, 12~17% filler, the wetting agent of 0.1-0.3%, propylene glycol-methyl ether of 0.4-3%, the defoaming agent of 0.1-0.4%,
0.1~0.3% dimethylethanolamine and the water of surplus.The aqueous primer surfacer uses above-mentioned aqueous dispersion for base-material, and film was both
Have the characteristics that epoxy-silicone resin high mechanical strength, antiseptic property are excellent, and there is polyurethane acrylic resin weatherability
The feature that energy is good, dicoration is high, it is easy to use, it is applied widely, it can effectively slow down the electrochemistry of metal base.
Although the environment-friendly type of aqueous primer surfacer is significantly better than oiliness floating coating, oiliness floating coating compares aqueous primer surfacer
Still there are significant advantage, including but not limited to rate of drying, film toughness and film hardness etc. on application performance.
In automobile finish repairing field, lacquer painting, which repairs the problem of bringing using the floating coating of sprayability, is, will be to be repaired
The position of benefit carries out large-scale finishing coat removal and polishing, heavy workload.
Therefore, using apply scratch-type floating coating by be the problem that can solve an effective way, apply the floating coating of scratch-type
If reaching preferable effect, face and urgent problem is: 1, having preferable viscosity, make to apply and scrape hand
Feel, can rapidly sense that the recess portion in priming paint is modified conducive to worker；2, wanting can be with the finishing coat of surrounding and i.e.
The problem of area of spraying is kept the consistent ductility of height, cracked to avoid the lacquer painting that temperature change is brought.
Summary of the invention
Car paint and its system are applied in the blade coating type based on thermoplastic acrylic resin that the object of the present invention is to provide a kind of
Preparation Method, the coating can show following excellent properties: 1, applying and scrape good hand touch, 2, solid content height, viscosity is not high, reduces VOC
Discharge；3, ductility can be consistent with finishing coat；4, good with the adhesive force of finishing coat；5, viscosity is low in the case where high temperature, low temperature
In the case where viscosity it is high.
Concrete scheme of the invention is as follows: car paint is applied in a kind of blade coating type based on thermoplastic acrylic resin, by
It is made including following parts by weight of component:
38-44 parts of thermoplastic acrylic resin；
20-25 parts of powder；
0.5-1 parts of wetting dispersing agent BYK-W966；
2-8 parts of pigment；
0.1-0.3 parts of pigment dispersing agent；
It is 100 parts by weight that dimethylbenzene, which is added to system gross weight,；
The thermoplastic acrylic resin is NeoCryl B-735 solid thermoplastic acrylic resin.
It is applied in car paint in the above-mentioned blade coating type based on thermoplastic acrylic resin, the powder includes carbonic acid
The weight ratio of calcium and silica flour, the calcium carbonate and silica flour is 1:4.
It is applied in car paint in the above-mentioned blade coating type based on thermoplastic acrylic resin, the pigment dispersing agent is
BYK-163。
In the preparation method for applying car paint in the above-mentioned blade coating type based on thermoplastic acrylic resin, including it is as follows
Step:
Step 1: thermoplastic acrylic resin being mixed with dimethylbenzene, when wetting dispersing agent is added after mixing；
Step 2: powder is added in the case where high-speed stirred in the mixture of step 1；Powder will be gradually added into, so that powder
Material can be evenly spread in system；
Step 3: pigment dispersing agent and pigment being added in the reaction system of step 2 and carry out high-speed stirred, and is being stirred
It is stirred at low speed and is discharged after uniformly.
In the preparation method for applying car paint in the above-mentioned blade coating type based on thermoplastic acrylic resin, the step
In rapid 1, incorporation time is 10-20 minutes；
In step 2, mixing time is 30-40 minutes；
In step 3, mixing time is 5-10 minutes.
The technical advantages of the present invention are that:
1, using the oleaginous system containing thermoplastic acrylic resin, the system that is able to maintain keeps low viscous during the preparation process
Degree, keeps high viscosity after packing, in this way in order to producing filling and blade coating feel；
2, it is addition powder that the present invention, which improves an effective way of blade coating feel, but in actual application process,
Problem appear to is that powder lot dispersing difficulty is also very big in the case where high-speed stirred, even if being dispersed by ultrahigh speed, still exist
Painting scrapes after rear spray paint that there are microdots, by preferably, can solve using wetting dispersing agent BYK-W966 to wetting dispersing agent
The certainly above problem, dispersion difficulty is low, and excellent finishing coat slickness, no microdot are able to maintain after spray paint；
3, for another angle, the presence of wetting dispersing agent BYK-W966 also improve powder for floating coating and
Adhesive force between finishing coat.
4, of the invention admittedly containing in range, NeoCryl B-735 solid thermoplastic acrylic resin is able to maintain and face
The synchronization ductility of paint finely tunes generally, for the ratio of thermoplastic acrylic resin and powder, is adapted to the overwhelming majority
Finishing coat ductility requirement.Reduce the finishing coat cracking situation detail for repairing thickness.
