Description
異なる配合物のレーザーマーキング効果を試験するために、これらの、このように装備された射出成形プラークをレーザーマーキングシステムに適用した。前述の試験について、Trumpf社による、20Wレーザー源を備えたNd:YAGマーキングレーザー(TruMark3020)を備えた装置を用いた。
前述の配合物1では、レーザーマーキングの最先端と称され得る配合物2、とりわけTPUと比較して、コントラストおよびエッジ鮮明度が改善されたことが見出された。これは、共吸収剤と共にマーキングされるとき、酸化ビスマスの量に比例して、デルタL*値がより高くなることによって証明される。これにより、前述の混合物が減少し、純粋な酸化ビスマスで得られるのと同じ性能が実現され、大抵の場合、費用を削減し、添加剤配合物の色影響を減らすことになる。
前述したのと同じ、試験試料を製造する方法を用いた、様々な試験を、ColorLite sph900装置を用いて測定した。この装置では、いわゆるK値(明るいコントラスト値)を測定することができる。デルタL*値と同様に、結果から、マーキング品質の指標が示されるが、光の反射率も識別される。値がより低いほど、マーキングコントラストはより良好である。
前述の配合物K5~K12では、配合物K4と比較して、コントラストおよびエッジ鮮明度が改善されることが見出された。これは、単独でマーキングされるとき、かつ共吸収剤と共にマーキングされるとき、酸化ビスマスの量に比例して、K値がより高くなることによって証明された。配合物K2および配合物K3は、ベンチマークと称することができる。同量の活性成分があれば、より低い費用で、アンチモン含有量を含まなくても、コントラストは、同等、またはさらに良好である。
さらに、本発明は以下の項目を含む。
[項目1]
熱可塑性ポリマー、酸化ビスマス、
ならびに、小板状ケイ酸塩、および無機の銅、コバルト、アルミニウム、または鉄を含有する顔料からなる群から選択される共吸収性添加剤を含むレーザーマーキング可能なプラスチックであって、酸化ビスマスに対する共吸収性添加剤の量が2~80質量%である、レーザーマーキング可能なプラスチック。
