Embodiments of the invention below are described.
Use ABS resin (acrylonitrile butadiene styrene resin) or ABS resin polymer alloy on the resinous principle of in the shaping resin material, allocating, also allocate at least a transistion metal compound and at least a coloring pigment.
Use the compound from copper, nickel and the selected transition metal of iron on transistion metal compound, pigment, dyestuff, the compound that is classified as other additives also can.On this transistion metal compound, for example can use phosphate such as oxides such as iron oxide, cupric oxide, copper sulfide, nickel sulfide sulfides, nickel phosphate, ferric phosphate, cupric phosphate etc.Through the combined effect of this transistion metal compound and carbon black described later or titanium dioxide, can not make the durability of resin forming product or the performance degradation on the mechanics, the laser radiation of available low output realizes that black is painted.At this, transistion metal compound itself also can as coloring pigment.
On coloring pigment, according to ratio allotment carbon black, according to ratio allotment titanium dioxide with respect to shaping resin total amount of material 0.1～10 quality % with respect to shaping resin total amount of material 0.001～0.02 quality %.Through at this concentration range allotment carbon black, improve absorption efficiency at the YAG of resin forming product laser, the thermal chemical reaction with the resinous principle of the absorption heating that promotes to utilize YAG laser can obtain the painted of black system easily.At this moment, also promote to utilize the foamable reaction of resinous principle of the irradiation of YAG laser, through breaking with the formed bubble of this foamable reaction portion, make the surface roughness Rp of laser irradiating part 1 increase, but through allocating titanium dioxide in above-mentioned concentration range, the high reflectance performance of the laser of the titanium dioxide that utilization is caused by the high index of refraction characteristic, prevent that laser from entering the portion inside of resin forming product, can be the painted top layer part that terminates in resin forming product with the black that utilizes laser radiation, suppress the carrying out of excessive foamable reaction again, can make that the surface roughness Rp of laser irradiating part 1 can be not excessive.Utilize the function of this titanium dioxide as the white color system coloring pigment again, order is coloured to the white or the light colour system of resin forming product itself, and can obtain with the black of laser irradiating part 1 is the contrast of painted excellence, and the decoration that can apply the observability excellence is handled.
When especially using average grain diameter to be 10～90nm on this carbon black, the laser absorption efficient of resin forming product when laser radiation more improves, and it is excellent especially to become coloration efficiency, and can suppress the deterioration of the mechanical strength of resin forming product.At this, when the average grain diameter of carbon black does not satisfy above-mentioned scope, possibly can't obtain sufficient laser absorption efficient, otherwise when surpassing this scope, the reduction of the intensity of resin forming product may take place.
On colouring agent, allocate the baking of titan yellow, iron oxide and green system again and burn pigment, the total amount of these compositions is deployed into scope with respect to shaping resin total amount of material 0.03～1 quality %.In this situation, can not reduce the coloring of utilizing laser radiation, it is higher that the tone of resin forming product is adjusted to brightness.
The allotment antimonous oxide is better in the shaping resin material, and in this situation, it is painted can more promoting to utilize the black of the laser irradiating part 1 of laser radiation.The addition of this antimonous oxide is made as better with respect to shaping resin total amount of material 0.2～0.8 quality %, and in this situation, it is painted utilizing laser radiation can obtain in flatness, reflecting feel and the observability black of excellent laser irradiating part 1 especially.Again, require the situation of flame retardancy many to switch structural component of distribution appliances 3, antimonous oxide can invest switch structural component of distribution appliances 3 flame retardancys using also as incombustible agent.
It is better following that the average grain diameter of this antimonous oxide is made as 2.0 μ m, and in this situation, but the profile of laser irradiating part 1 can not carry out distinct describing faintly, and reduces the surface roughness Rp of laser irradiating part 1, can obtain excellent especially flatness.Again, suppress the cantilever impact strength and reduce, can be implemented in the sufficient impact characteristics that requires on the switch structural component of distribution appliances 3.At this, do not set the lower limit of the average grain diameter of antimonous oxide especially, but the following 0.1 μ m that is limited in the practicality.
Again, in order not make the distinctive aging phenomenon of inhibition resin forming product of the coloring reduction that utilizes laser radiation, adjustable various additives.Through using additive, the surface that can suppress the surface of laser irradiating part 1 of resin forming product and non-laser irradiating part 2 is because of wearing out in indoor use for a long time.
When obtaining resin forming product, can utilize general injection molding will allocate as the above-mentioned resulting shaping resin material forming of composition, needn't use special forming technique, can adopt cheap and be easy to be shaped.At this moment, through the flatness of the inner face of adjusting shaping dies, the surface roughness Rp of resin forming product is shaped as below the 0.5 μ m.At this, do not limit the lower limit of the surface roughness Rp of resin forming product especially, but, be 0.01 μ m haply at general die forming.
With this resin forming product switch structural component of distribution appliances 3 is shaped, particularly, it is better to be configured as the handle 4 that staff directly touches.
When resin forming product being decorated processing, with power density 5-40kW/cm 2, pulsewidth 70～200nsec condition irradiation YAG laser, describe desired literal or style on the resin forming product surface by this.
The surface roughness Rp that will utilize laser radiation to be coloured to the laser irradiating part 1 of black this moment forms below the 3 μ m.The lower limit of the surface roughness Rp of laser irradiating part 1 changes because of laser irradiation condition at this moment, but is 0.01 μ m haply.
Fig. 1～3 expressions are configured as the example of the switch structural component of distribution appliances 3 of handle 4.
At the example shown in Fig. 1,2, forming at the surperficial central portion that forms the handle 4 that becomes rectangle on the plane graph can be in order to the display part 5 of the switch that is shown as which kind of distributor, in the longitudinally both sides of handle 4, form the decoration pattern of the band shape that constitutes with laser irradiating part 1 with respect to display part 5.Each is decorated pattern and is used in long many (being each 32 in illustrative example) the parallel lines arranged side by side 6 of the direction of vertical quadrature of handle 4 and constitutes.A plurality of laser irradiating parts 1 of each lines 6 usefulness point-like constitute.At this, laser irradiating part 1 through with YAG laser (wavelength 1064nm) towards longitudinal scanning handle 4 surface of lines 6 and irradiation intermittently and forming.Part beyond the laser irradiating part 1 on handle 4 surfaces forms non-laser irradiating part 2.
In example shown in Figure 3,,, form roughly foursquare decoration pattern on the plane graph that constitutes with laser irradiating part 1 at the sidepiece longitudinally of handle 4 with respect to display part 5 with Fig. 1, the 2 the same handles 4 that form.These a plurality of laser irradiating parts 1 of decorating the pattern point-like constitute.At this, laser irradiating part 1 and Fig. 1,2 the same through with YAG laser towards longitudinal scanning handle 4 surfaces of lines 6 and irradiation intermittently and forming.Part beyond the laser irradiating part 1 on handle 4 surfaces forms non-laser irradiating part 2.
So because of the surface roughness Rp with laser irradiating part 1 forms below the 3 μ m, and the surface roughness Rp of the non-laser irradiating part 2 of irradiating laser does not form below the 0.5 μ m, the sense of touch when hand touches is fully level and smooth, does not have the difference sense.Again, between laser irradiating part 1 and non-laser irradiating part 2, obtain excellent contrast, and obtain the outward appearance of glossy sense, and as the some lamp switch of the illumination of residential lighting utensil, shop illumination utensil, facility illumination etc. the time, can obtain excellent outward appearance, also excellent on the value of interior decoration.Again when form decorating pattern, because of not can as print with as use transfer film, can reduce manufacturing expense, and can reduce discarded object.In addition, can not form printed layers or film, when regeneration, can not sneak into this impurity, delete the time manpower or the expense of removing impurity, and prevent because of the physical property of sneaking into the impurity regenerate reduces or generation such as bad order regeneration easily.
Below with embodiment in detail the present invention is described in detail.
