- the flexural modulus of the obtained molded product can exceed 30 GPa.
- the reinforced thermoplastic polyester resin composition of the present invention is characterized in that this value is in the range of 165 ° C. or higher and lower than 190 ° C. when the temperature-decreasing crystallization temperature determined by a differential scanning calorimeter (DSC) is TC2. ..
- the TC2 is 10 ° C./min after being heated to 300 ° C. at a heating rate of 20 ° C./min under a nitrogen stream using a differential scanning calorimeter (DSC) and held at that temperature for 5 minutes. It is the top temperature of the crystallization peak of the thermogram obtained by lowering the temperature to 100 ° C. at the rate of.
- the TC2 is 190 ° C.
- the crystallization rate of the polyester resin composition becomes high and the crystallization in the mold occurs quickly. Therefore, the propagation speed of the injection pressure tends to decrease particularly in the composition containing a large amount of fiber-based reinforcing material. As a result, the adhesion between the injection product and the mold becomes insufficient, and the effect of crystallization shrinkage causes the fiber-based reinforcing material to stand out on the surface of the molded product, resulting in a poor appearance of the molded product. .. In that case, a method of delaying the solidification of the molded product by raising the mold temperature to a high temperature of 120 to 130 ° C. can be considered, but this method improves the surface gloss and appearance in the central portion where the injection pressure is high in the mold.
- the crystallization rate becomes too slow, and the slow crystallization may cause mold release failure due to sticking to the mold, or deformation may occur at the time of protrusion. ..
- the pressure during molding makes it easier for the resin to penetrate deeper into the grain, so the grain is not deep enough because the grain shifts when the resin in the mold shrinks or is released. It tends to be uniform, and it becomes difficult to obtain a good grained appearance. Since the reinforced thermoplastic polyester resin composition of the present invention has been adjusted so as to have an optimum TC2 in consideration of these concerns during molding, it has a good appearance and molding even when the mold temperature is 100 ° C. or lower. You can get sex.
- the TC2 can also be adjusted by adjusting the content of the polyethylene terephthalate resin (B) and the copolymerized polyethylene terephthalate resin (D).
