Embodiment 1
[0204]
[0205] The pellets (resin composition) for forming a light-transmitting member and the pellets for forming a light-absorbing member (light-absorbing resin composition) described in Table 1 below were produced.
[0206] Specifically, each component shown in Table 1 below, that is, components other than glass fibers, was weighed in the ratio shown in Table 1 (the unit is mass %), and after dry mixing, a twin-screw screw was used to A cassette-type weighing feeder (manufactured by Kubota Corporation, CE-W-1-MP) was fed from the screw root of a twin-screw extruder (manufactured by Toshiba Machine Co., Ltd., TEM26SS). In addition, the glass fiber was injected into the above-mentioned twin-screw extruder from the side of the extruder using a vibrating box-type weighing feeder (manufactured by KUBOTA Corporation, CE-V-1B-MP), and mixed with the resin component and the like. The pellets for forming a light-transmitting member (resin composition) and the pellets for forming ...
Embodiment 2、 Embodiment 3
[0221] Embodiment 2, embodiment 3, comparative example 1, comparative example 2, comparative example 3
[0222] In Example 1, it carried out similarly except having changed as shown in Table 1. However, since comparative examples 1 to 3 were not welded, the total energy input amount could not be measured.
[0223]
[0224] As is clear from the above results, the resin composition of the present invention has a high light transmittance and is excellent in laser welding properties (Examples 1 to 3). Additionally, if figure 2 As shown, even if the total energy accompanying laser irradiation is small, high laser weldability can be achieved.
[0225] In contrast, even when other flame retardants and flame retardant auxiliary agents were used, the light transmittance was low, and laser welding was not performed (Comparative Examples 1 to 3).
