Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of plastic cement vacuum plating product showering finish paint, it is further related to
Preparation method.
Background technology
The finish paint of vacuum plating product in the market is generally using the technique of spraying, and it is low to there is production and construction efficiency,
Loss is painted during spraying application big, the easy lifting of paint film, the shortcomings of easily turning white.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of for plastic cement vacuum plating product（Such as Christmas ball etc. is moulded
Glue vacuum plating jewelry or toy）The finish paint of leaching coating process construction, this finish paint construction technology is with similar product existing on the market
Condition the characteristics of gloss, richness high construction efficiency high facilitate, is adapted to automatic stream than having good drying property, adhesive force, good leveling property
Waterline production operation, compared to the technique of spraying production, greatly improves production efficiency and reduce loss, wide market.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of finish paint for the construction of plastic cement vacuum plating product leaching coating process, including varnish or colored paint, also including dilution
Agent, the varnish is made up of the component of following mass percent：1/4 second nitrocotton 30 ~ 40%, aldehyde ketone resin 10 ~ 20%, amino
Resin 3-5%, function additive 6.5% ~ 11%, mixed solvent 30 ~ 40%.Aldehyde ketone resin can be with highly effective in above-mentioned each component
Ground improves dryness, gloss, richness, amount of solid content etc. of coating, the resin to the dryness of plastic cement vacuum plating product finish paint,
Gloss, richness, amount of solid content are significantly improved, and also have certain improvement to adhesive force.Amino resins and adhesion promoter
Addition, plastic cement vacuum plating product finish paint is improved significantly to the adhesive force of ground, while can also improve plastic cement vacuum
The hardness of electroplated product finish paint, makes it be not easy to scratch.Due to the addition of nitro architectural characteristic and aldehyde ketone resin so that modeling
Glue vacuum plating product finish paint can seem that comparing is crisp, easily bursts after bending, and the addition of plasticizer is showed to improve this
As.
1/4 second axite selection nitrogen content is less than 12.6%, and nitrocellulose cellulose content is 60-75%, and ethanol content is
1/4 second axite of 25-40%.Inventor's research finds, with various alkyd resins, aldehyde ketone after the nitrocotton dissolving of the parameter
Resin, amino resins have good compatibility.
In terms of mixed solvent, due to different from traditional spraying coating process, therefore we devise one by testing repeatedly
Set different from the scheme of conventional solvent system, solve the finish paint of conventional spray type plastic cement vacuum plating product because solvent is strong and weak,
The problem that paint film caused by dryness and construction problem easily turns white, lifting, levelling be not good, also solves because showering construction is led
The easy stream pendant for causing, the problem of the bad control of film thickness.Mixed solvent used of the invention is contained in terms of percent by volume 100%
The isopropanol of 20-30%, the isobutanol of 25-35%, the ethyl acetate of 15-30%, the butanone of 5-10%, the DAA of 10-20%,
The butyl glycol ether of 2-10%.
Described to be counted with varnish quality as 100%, function additive is 3 ~ 5% plasticizer, and 0.5 ~ 1% levelling agent, 3-5%'s is attached
Adhesion promoter.
The colored paint is that at least one preparation in mute powder, dye water, mill base, amino resins, function additive is added by varnish
Form.Add mute powder, dye water, mill base to can be used to mixing colours, mute degree；Add amino resins, function additive（Such as plasticizer, stream
Flat agent, adhesion promoter）The parameters such as adhesive force, hardness, pliability can be adjusted.
Diluent is most important for the influence that the showering of vacuum plating product finish paint is constructed, and the dissolving power of diluent is too strong,
Easy lifting, too weak to influence adhesive force, diluent too quick-drying can cause the surface effects such as levelability not good, can also cause
Turn white, cloudy colour, diluent too slow curing easily produces sagging phenomenon.Therefore we by test repeatedly it is above-mentioned it is strong, weak, fast,
Equalization point is found between slow, that is, ensures adhesive force and surface effect, construction effect is ensured again.Diluent used of the invention presses volume
Percentage 100% is counted, and is made up of following component：The isopropanol of 20-30%, the isobutanol of 20-30%, the ethyl acetate of 20-30%, 5-
10% methyl iso-butyl ketone (MIBK), the DAA of 10-20%.
The above-mentioned preparation method of finish paint for the construction of plastic cement vacuum plating product leaching coating process is：First in mixed solvent
Nitrocotton is slowly added into while stirring with dispersion machine, after side adds aldehyde ketone resin while stirring after nitrocotton dissolving completely, treats aldehyde
Ketone resin sequentially adds amino resins, plasticizer, levelling agent, adhesion promoter while stirring after dissolving, and stirs.
The above-mentioned construction method of finish paint for the construction of plastic cement vacuum plating product leaching coating process is：With diluent by varnish
Or colored paint opens the optimum showering working viscosity of dilute to 9-10 seconds, tested with No. 2 cups in rock field, viscosity mix up after can directly on
Coater carries out showering, 60 DEG C of baking ovens is put into after showering is complete and toasts i.e. completion construction in 30 minutes.
The present invention has the advantages that：
The present invention has broken traditional plastic cement true by the collocation use to resin in formula and the structure of mixed solvent system
The main Construction Mode based on jet printing type of dummy plating product, drastically increases production and construction efficiency, while also greatly changing
The easy lifting of paint film under conventional construction method has been apt to it, has easily turned white, the shortcomings of surface effect is not good.This formula and technique are especially suitable for together
A kind of finish paint of color produces construction in enormous quantities.
Specific embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
A mute finish paint for being used for the showering of vacuum plating surface is prepared, is comprised the following steps that：
First plastic cement vacuum plating product showering varnish (gloss oil) is made by formula as below and above-mentioned varnish preparation method：
Wherein, mixed solvent formula is：
The finished product finish paint for being directly used in construction can be made by formula as below again：
Vacuum plating product showering construction topcoat formulation：
Wherein diluent formulation can select the one of which in three below embodiment：
Mute finish paint Product checking, the skill of the vacuum plating surface showering being made according to the formula of above-described embodiment 1 ~ 3 and step
Art index such as following table：
