Description
Technical field
The present invention relates to a kind of coating, especially a kind of coating that is used for laser sculpture and preparation method thereof and a kind of overbrushing laminate.
Background technology
At present, plastic cement keyboard such as cell phone keyboard, computer keyboard etc. are more and more higher to the color and the performance demands of various symbols on the keyboard, European Union is more and more higher to the environmental requirement of electronic product simultaneously, and rules such as RoHS and REACH are implemented in succession, and is more to the coating products restriction that is used for plastic parts.Be to realize on keyboard the symbol of various different colours, common have screen painting and two kinds of methods of laser sculpture; The main problem is-symbol of screen painting is clear inadequately, and to half tone accuracy requirement height, yield rate is low; Clear and the difficult drop-off of symbology effect of laser sculpture, the yield rate height, but the initial failure period in and early stage higher to the accuracy requirement of machine is longer, causes the reduction of operational difficulty of direct labor and toning working efficiency.
Be used for the thermoplastic acrylic paint of plastic cement surface of keyboard spraying at present, mostly adopt the method for two-layer spraying to reach the color requirement.The first layer display backlight color, the second layer shows the housing color, the coating of this two-layer color all has alcohol resistance to satisfy the process of radium carving back by the ethanol wiping.The subject matter that this two-layer spraying coating process exists has 2 points, and the one, quite high for satisfying the second layer to the uniformity requirement of spraying film thickness just by the long initial failure period of the saturating complete unaffected needs of the first layer of laser carving, easily cause the edge residual; The 2nd, when laser intensity is not to be in the second layer just to be carved and during the complete impregnable situation of the first layer, unlikely for satisfying with the saturating condition of first coating carving, second coating often exists color residual, need to solve, have the waste on the bigger human and material resources by the ethanol scouring of long period.For guaranteeing that first coating do not wiped by ethanol, normally add vinyl chloride-vinyl acetate resin therein and improve, and European Union's rules explicit order requires single content of halogen to be lower than 900ppm.
Summary of the invention
Debug the laser sculpture complicated condition in the prior art in order to overcome, and the problem of not environmental protection of used coating, the invention provides a kind of coating, when preparing coating by this coating, technology is simple, and used coating environmental protection.
Coating disclosed by the invention comprises primary coat component and finish paint component, and wherein, described primary coat component comprises bottom coating resin, photostabilizer, primary coat pigment and primary coat solvent, and described bottom coating resin is a second-order transition temperature less than 55 ℃ thermoplastic acrylic resin; Described finish paint component comprises top-coat resin, finish paint pigment and finish paint solvent, and described top-coat resin is that second-order transition temperature is 80-120 ℃ a thermoplastic acrylic resin.
Simultaneously, the invention also discloses the using method of above-mentioned coating, comprising:
A, in plastic basis material surface spraying primary coat component, solidify 10-15min down at 55-60 ℃ then and form undercoat;
B, on undercoat the spray paint component, solidify down 10-15min at 55-60 ℃ then and form top coat layer;
C, adopt laser that the substrate surface that forms behind undercoat and the top coat layer is carved, the intensity of laser makes top coat layer be worn by carving, shows the undercoat color and undercoat is not destroyed.
In addition, the invention also discloses a kind of overbrushing laminate, comprise base material and be positioned at its surperficial coating, described coating comprises undercoat and top coat layer, and undercoat is between top coat layer and base material; Described undercoat comprises bottom coating resin, photostabilizer, primary coat pigment, and described bottom coating resin is a second-order transition temperature less than 55 ℃ thermoplastic acrylic resin; Described top coat layer comprises top-coat resin, finish paint pigment, and described top-coat resin is that second-order transition temperature is 80-120 ℃ a thermoplastic acrylic resin.
Coating provided by the present invention can especially be suitable as the keyboard or the button of electronic product as the parts of any needs pattern backlight.Can as required the top coat layer of pattern part backlight be carved, the undercoat of this part is come out, thus the display backlight pattern.Described body material can need the body material of the parts of pattern backlight for the formation that is applicable to of routine, is preferably plastics
The present inventor finds that by use low Tg (preferably less than 55 ℃) thermoplastic acrylic resin and photostabilizer at the primer base that is used for undercoat, supercoat is not burnt when the laser radiation of accepting the short period of time; Form at the finish paint that is used for top coat layer simultaneously and use high Tg (being preferably greater than 80 ℃) thermoplastic acrylic resin, under laser radiation, burn disappearance rapidly, thereby form complete clear pattern.Under this technology, because undercoat has anti-carving, a wider range when carrying out the laser debugging, can suitably improve laser intensity, guarantee that top coat layer is fallen by carving fully, thereby avoid uneven and to avoid damaging the top coat layer that undercoat causes residual because of thickness, the process that needs the ethanol wiping, therefore, can shorten debugging laser intensity and required time of scouring, thereby improve the production efficiency of multi-layer coating product; Avoided simultaneously adding high risk anti-pure material vinyl chloride-vinyl acetate resin, reached requirements of green environmental protection.
