Abstract
The invention relates to the technical field of coatings, in particular to shower coating finish paint for a plastic vacuum electroplated product, and a preparation method of the shower coating finish paint. The finish paint for construction of a shower coating process of the plastic vacuum electroplated product comprises varnish or colored paint and a diluent, wherein the varnish comprises the following components in percentage by mass: 30-40 percent of 1/4-second nitro-cotton, 10-20 percent of aldehyde ketone resin, 3-5 percent of amino resin, 6.5-11 percent of a functional aid and 30-40 percent of a mixed solvent. By the matched using of resin in a formula and the construction of a mixed solvent system, a construction mode of main spray-coating of a conventional plastic vacuum electroplated product is broken, and the production construction efficiency is greatly improved; meanwhile, the defects of proneness to lifting, proneness to whitening, poor surface effect and the like of a lower paint film of a conventional construction method are greatly overcome. The formula and the process are quite suitable for large-batch production construction of the finish paint of the same color.
Description
Technical field
The present invention relates to technical field of coatings, be specifically related to a kind of plastic cement vacuum plating product showering finish paint, also relate to its preparation method.
Background technology
The finish paint of vacuum plating product in the market generally adopts the technique of spraying, there is production and construction efficiency low, and it is large to paint loss in spraying application process, and paint film easily stings the end, the shortcoming such as easily to turn white.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of finish paint for the plastic cement vacuum plating product leaching coating process construction such as (such as Christmas ball plastic cement vacuum plating jewelry or toy), this finish paint construction technology is compared with existing like product on the market has that drying property is good, sticking power, good leveling property, gloss, fullness ratio high high construction efficiency feature easily, be applicable to Automatic Production Line operation, compare the technique that spraying is produced, greatly enhance productivity and reduce the wastage, wide market.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of finish paint for the construction of plastic cement vacuum plating product leaching coating process, comprise varnish or colored paint, also comprise thinner, described varnish is made up of the component of following mass percent: 1/4 second nitro-cotton 30 ~ 40%, aldehyde ketone resin 10 ~ 20%, aminoresin 3-5%, functional agent 6.5% ~ 11%, mixed solvent 30 ~ 40%.In above-mentioned each component, aldehyde ketone resin effectively can improve the dryness, gloss, fullness ratio, amount of solid content etc. of coating, this resin is significantly improved to the dryness of plastic cement vacuum plating product finish paint, gloss, fullness ratio, amount of solid content, also has certain improvement to sticking power.Adding of aminoresin and adhesion promoter, the sticking power of plastic cement vacuum plating product finish paint to ground is improved significantly, also can improve the hardness of plastic cement vacuum plating product finish paint simultaneously, make it be not easy to scratch.Due to adding of nitro architectural characteristic and aldehyde ketone resin, make plastic cement vacuum plating product finish paint can seem more crisp, easily explosion after bending, adding of softening agent is to improve this phenomenon.
Within described 1/4 second, axite selects nitrogen content lower than 12.6%, and nitrocotton cellulose content is 60-75%, and ethanol content is 1/4 second axite of 25-40%.Contriver studies discovery, and the nitro-cotton of this parameter dissolves later and various Synolac, aldehyde ketone resin, aminoresin have good compatibility.
In mixed solvent, owing to being different from traditional spraying coating process, therefore we are through repeatedly testing, devise a set of scheme being different from conventional solvent system, the paint film that the finish paint solving conventional spray type plastic cement vacuum plating product causes because of solvent power, dryness and construction problem easily turns white, stings the not good problem of the end, levelling, also the easy stream pendant because showering construction causes is solved, the problem of the bad control of film thickness.The present invention's mixed solvent used in volume percent 100%, the Virahol containing 20-30%, the isopropylcarbinol of 25-35%, the ethyl acetate of 15-30%, the butanone of 5-10%, the diacetone alcohol of 10-20%, the butyl glycol ether of 2-10%.
Described in varnish quality for 100%, functional agent is the softening agent of 3 ~ 5%, the flow agent of 0.5 ~ 1%, the adhesion promoter of 3-5%.
Described colored paint is that at least one added in mute powder, dye water, mill base, aminoresin, functional agent by varnish is prepared from.Add mute powder, dye water, mill base can be used for mixing colours, mute degree; Add aminoresin, functional agent (as softening agent, flow agent, adhesion promoter) can regulate the parameters such as sticking power, hardness, snappiness.
The impact that thinner is constructed for the showering of vacuum plating product finish paint is most important, the solvency power of thinner is too strong, easily sting the end, too weakly sticking power may be affected, thinner too quick-drying can cause the surface effects such as levelling property not good, also can cause turning white, cloudy colour, thinner too slow curing easily produces sagging phenomenon.Therefore we by repeatedly to test above-mentioned strong, weak, fast, slow between find trim point, namely ensure sticking power and surface effect, ensure construction effect again.The present invention's thinner used by volume per-cent 100%, is made up of following component: the Virahol of 20-30%, the isopropylcarbinol of 20-30%, the ethyl acetate of 20-30%, the methyl iso-butyl ketone (MIBK) of 5-10%, the diacetone alcohol of 10-20%.
The preparation method of the above-mentioned finish paint for the construction of plastic cement vacuum plating product leaching coating process is: first in mixed solvent, slowly add nitro-cotton while stirring with dispersion machine, after nitro-cotton dissolving completely, limit adds aldehyde ketone resin while stirring, treat that aldehyde ketone resin adds aminoresin, softening agent, flow agent, adhesion promoter after dissolving while stirring successively, stir.
The constructional method of the above-mentioned finish paint for the construction of plastic cement vacuum plating product leaching coating process is: with thinner, varnish or colored paint are opened rare optimum showering working viscosity to 9-10 second, with the cup test of No. 2, rock field, directly can go up coater after viscosity mixes up and carry out showering, put into 60 DEG C of baking ovens after showering is complete and toast and namely complete construction in 30 minutes.
The present invention has following beneficial effect:
The present invention passes through the collocation use of resin and the structure of mixed solvent system in formula, break the Construction Mode of traditional plastic cement vacuum plating product mainly based on jet printing type, drastically increase production and construction efficiency, also under significantly improving conventional construction method, paint film easily stings the end simultaneously, easily turn white, the shortcomings such as surface effect is not good.Construction produced in enormous quantities by the finish paint that this formula and technique are applicable to same color very much.
Embodiment
Below in conjunction with embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention, is not limitation of the invention.
Prepare a mute finish paint for vacuum plating surface showering, concrete steps are as follows:
First make plastic cement vacuum plating product showering varnish (gloss oil) by following formula and above-mentioned varnish preparation method:
Wherein, mixed solvent formula is:
The finished product finish paint being directly used in construction can be made again by following formula:
