Abstract

The present invention relates to a kind of method of color printing foam plastics, its foaming body is before the secondary sulfur adding treatment, soaked through liquid medicine earlier, make the surface of foaming body form matsurface, again matsurface is given heat drying after, coat colorant again, on matsurface, form dyed layer, and heat with strong beam and to carry out the secondary sulfur adding treatment again after the fixation, dyed layer is able to and the tight set of foaming body, and reaches the purpose that high-quality does not fall lacquer.

Description

The method of color printing foam plastics

The present invention relates to a kind of method of direct colour print, relate in particular to a kind of method of color printing foam plastics.

Generally carry out when painted at present for fork in the sole, its great majority are to carry out after adding the sulphur cure process, its process as shown in Figure 6, behind secondary sulfur adding treatment 40, its foaming body 50 surfaces as shown in Figure 7 form a smooth top layer 51 naturally, give painted 41 again handles in the top layer 51 of this foaming body 50, make in 51 outsides, smooth top layer formation dyed layer 60, as shown in Figure 8, promptly finish the finished product of pitching in the existing painted sole 42, so the set strength of the dyed layer 60 of structure is not enough, and the bad quality situation that often has full wafer to fade takes place, and again because the surface on its top layer 51 is smooth really, make dyed layer 60 to adhere to strength not enough, often when colorant is painted, because of the cohesive force of colorant itself greater than this adhesive force, and colorant excessively cohesion or mobile uneven phenomenon take place, therefore necessity of improvement arranged.

In order to overcome the deficiency of above-mentioned prior art, main purpose of the present invention is: a kind of method of color printing foam plastics is provided, so that the tight set of dyed layer and foaming body, and the quality of raising finished product.

For finishing above-mentioned goal of the invention, the invention provides a kind of method of color printing foam plastics, it is characterized in that: before foaming body carries out the secondary sulfur adding treatment, give the liquid medicine surface treatment earlier, behind the formation matsurface, in temperature is 50 to 60 ℃, after carrying out dry run under the condition of 5 to 8 minutes time, colorant in matsurface and form the dyed layer that has pattern, carry out powerful optically focused again and heated 5 to 8 minutes, after the fixation, impose the secondary sulfur adding treatment again and obtain finished product.

As shown in the above description, the present invention compared with prior art has following advantage:

Utilize above-mentioned process, make dyed layer can be really and foaming body be combined into one, not having the situation that fades after the use takes place, the color that can keep really pitching in the sole is under the most bright-coloured state, and because the formation of matsurface, make adhesive force between dyed layer and foaming body really greater than the cohesive force of dyed layer colorant itself, make the painted more accurate of dyed layer, produce random moving or excessively cohesion and be unlikely, thereby reach high-quality painted purpose.

For realizing technical scheme of the present invention, further specify preferable possible embodiments of the present invention below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is a flow chart of the present invention.

Fig. 2 is the not foaming body profile of sulfur adding treatment of the present invention.

Fig. 3 is a foaming body rough surface face generalized section of the present invention.

Fig. 4 forms the foaming body generalized section of dyed layer for the present invention.

Fig. 5 is a finished product schematic diagram of the present invention.

Fig. 6 is existing flow chart.

Fig. 7 is the generalized section behind the existing foaming body secondary sulfur adding treatment.

Fig. 8 is the generalized section that forms dyed layer on the existing foaming body top layer.

As Fig. 1, shown in 2, foaming body 10 of the present invention is before carrying out the secondary sulfur adding treatment, earlier carry out surface treatment 30 with liquid medicine, make its foaming body 10 top layers form a concavo-convex matsurface 11, as shown in Figure 3, its liquid medicine is to make with the solvent of general erodable plastic foam material, the liquid of toluene class for example, after treating that matsurface 11 forms, dry 31 handle again in addition, drying is about 5 to 8 minutes under the environment of about 50 to 60 ℃ of temperature, make the convex-concave surface place bone dry of matsurface 11, this factor that obstruction colorant will be adhered to is removed, go up colorant 32 again, on matsurface 11, form the dyed layer 20 of required pattern, as shown in Figure 4, the colorant of this dyed layer 20 infiltrates in the matsurface 11 really, with the area of strengthening adhering to, and gives fixation 33 processing, pack high light with high temperature is heated at dyed layer 20, warm-up time is about 5 to 8 minutes, makes foaming body 10, matsurface 11, the phenomenon of local fusing takes place in the colorant of dyed layer 20 simultaneously, and dyed layer 20 is bonded on the foaming body 10 really, carry out secondary sulfur adding treatment 34 again, and obtain finished product 35, promptly as shown in Figure 5, its dyed layer 20 is more combined closely with foaming body 10 and is integral.

Claims

1, a kind of method of color printing foam plastics, it is characterized in that: before foaming body carries out the secondary sulfur adding treatment, give the liquid medicine surface treatment earlier, after forming matsurface, in temperature is 50 to 60 ℃, after carrying out dry run under the condition of 5 to 8 minutes time, colorant in matsurface and form the dyed layer that has pattern, carry out powerful optically focused again and heated 5 to 8 minutes, after the fixation, impose the secondary sulfur adding treatment again and obtain finished product.
