In recent years, various engineered blastinoks have been used as alternatives to metals. These engineering plastics had excellent mechanical strength, but when printing some kind of text or pattern on these products,
If the ink used does not have sufficient adhesion to these engineering plastics and is used for a long time, the printed ink may fall off due to physical force or chemical effects and may not perform its original function. There was a problem that made it impossible. For this purpose, we print on plastic molded products for the purpose of improving their wear resistance, and by impregnating the ink from the surface into the resin, unlike the state where the ink is floating on the surface, the surface of the plastic is slightly There is a penetrant printing method in which the ink inside the paper is exposed on the surface even when it wears out, so the characters do not disappear. This method has been widely put into practical use by using dyes that can be sublimated by heat transfer, such as disperse dyes, on fabrics made of polyethylene terephthalate or acrylic, or on anodized surfaces of aluminum. When applying this technical injection molding method to the molding of plastic molded products, it is necessary to use the same resin as that used in fabrics, such as heat-transfer sublimable dyes, which are most commonly used in fabrics. When polyethylene terephthalate resin is used for printing, unlike spinning, it cannot be stretched during molding, and the resin has a high crystallization temperature, making the molded product brittle. In practice, it has poor impact resistance and is difficult to use unless it is processed, such as by adding glass fiber. Furthermore, even if glass fibers are added, the problem arises that the surface is not dyed uniformly because glass fibers are not dyed.

When making individual products, there is a problem that the resin does not flow all the way to the end of the mold, making the quality of the product unstable. Therefore, the use of polycarbonate resin, which is not used as fiber, may be considered. Like polyester, polycarbonate resin can be dyed with sublimation heat transferable dyes, and the dyed products have sufficient durability, impact resistance, and high heat distortion temperature, making it suitable for applications where dyes are sublimated and transferred at high temperatures. However, the problem is that the resin does not flow well during hot melting, making it difficult to mold, and the finished product tends to retain residual strain and may easily crack depending on the usage conditions. was there.

The present invention has found a composition that improves these moldability defects, allows stable dyeing with dyes, and provides dyed products with good durability. That is, it uses polycarbonate resin as the main material and styrene resin as an auxiliary material. Styrenic resin lacks heat resistance when used alone, and if it is heated to a temperature high enough to transfer dyes such as disperse dyes that undergo heat transfer and sublimation, it will soften and the molded product will become deformed, making it unusable. However, by mixing it with polycarbonate resin, it is possible to prevent deformation even when heated and pressurized to the dye transition penetration temperature, and polycarbonate resin originally has dye retention (heat resistance, chemical resistance). In addition, the viscosity of the resin during hot melting can be lowered, making stable molding possible.

As the styrene resin to be added to the 11-carbonate resin, polystyrene resin, copolymer or blend resin of styrene and butadiene, acrylonide 11-butadiene-styrene resin, and acrylonitrile-styrene resin are suitable. Among styrene-based resins, resins containing a large amount of Aku 110 Nido 11L resin have excellent dye retention and heat resistance, and resins with additions include Realarylonitrile-butadiene-sterene resin and Aku+10 Nido 11 Ruthyrene resin. The amount of addition can be increased. Furthermore, both the acrylonide 11-rubutadiene-styrene resin and the acrylonide 11-rutyrene resin have good impact resistance and breakage resistance, and are excellent as sub-materials because they rarely impair the performance inherent to polycarbonate resins.

The effective amount of polystyrene resin added to the polycarbonate resin is 1 to 50% by weight, and 5 to 50% is most effective in terms of moldability of the resin, ease of dyeing, and heat resistance of the dye.

If the amount of polystyrene resin added is small, there is no effect of reducing the viscosity during hot melting of the resin, resulting in poor moldability. If the amount of polystyrene resin added is too large, the heat resistance of the resin will be poor, resulting in poor dye penetration. Thermal deformation occurs in the product during the process, causing practical problems.

It is preferable that the polycarbonate resin and the polystyrene resin are kneaded in advance using an extruder. A polybutylene terephthalate resin made by condensation of dimethyl terephthalate and 14-butanediol may be added as an additive to balance the heat resistance and moldability of the resin, and to reduce the cost.

The melt viscosity of polybutylene terephthalate resin is lower than that of polycarbonate resin, the unit price is lower than that of polycarbonate resin, and it is easily dyed with a heat-transferable sublimation dye. Therefore, it may be added as an extender to the polycarbonate resin or as an additive for improving moldability. Regarding the amount of polyethylene terephthalate resin added to the polycarbonate resin, if the amount added is large, problems will arise not only in the miscibility but also in the miscibility with the auxiliary materials polys and terene resin. Therefore, the mixing is more stable if a method is used in which the polycarbonate resin and the polybutylene terephthalate resin are mixed in advance and then mixed with the Bo-11 styrene resin. The amount of sulpolybutylene terephthalate resin added to the total is 1 to 30% by weight, preferably 3 to 10% by weight from the viewpoint of mixability.

Effective inorganic substances include talc, mica, titanium oxide, barium sulfate, calcium hydroxide, and calcium carbonate, which are usually used as additives for gelaste. These inorganic substances have small particle sizes and virtually do not cause problems with the dyeing condition of the surface of the molded product even when they are not dyed to the inorganic substance, but when glass fibers have long fiber diameters and lengths, the glass floating on the surface may Since it is not dyed, there is a problem that the dye concentration of the product may be reduced or it may appear uneven.
