Description
本発明は、散乱有色顔料の吸収および散乱係数の決定に使用するための、散乱有色顔料の特性決定の方法に関する。それはまた、色合わせ法および、とりわけ、有色顔料混合物のための色合わせ法に関する。本発明はまた、該方法を実施するための顔料の特性決定システムに関する。
本発明の第一の態様に従うと、我々は散乱有色顔料の、吸収および散乱係数の決定に使用するための、散乱有色顔料を特性決定する方法を提供し、該方法は:
i)複数の異なる容積分率における、>0.6ミクロンの粒度(particle size)をもつ実質的に非吸収性の散乱顔料との、散乱有色顔料の混合物、の反射スペクトルを得る、
工程を含んでなる。
Cells 89(2005)319−349中に記載された方法、により決定されることができる。
iii)複数の異なる容積分率において、波長の関数として、弱く散乱する黒色顔料の吸収係数を得て、そして
iv)複数の異なる容積分率において、黒色顔料との散乱有色顔料の混合物の、更なる反射スペクトルを得る:
工程を含む。
(v)反射スペクトルおよび更なる反射スペクトルを合わせ、そして散乱有色顔料の容積分率と波長の関数として散乱有色顔料に対するクベルカ・ムンク吸収および散乱係数を計算する、
工程を含む。
(vi)工程(v)で計算される係数を使用して、標的の反射スペクトルに分光学的に一
致するために必要な、散乱有色顔料の容積分率を決定する、
工程を含む。
この方法は、散乱有色顔料が広範囲の波長にわたり信頼して特性決定されることができるために、色合わせをより正確に実施することができるので、有利である。更に、該方法は、色合わせを達成するために必要な大きい粒度の散乱有色顔料の容積分率を、顔料混合物を調製する前に決定させる。
(vii)計算される容積分率に従って調合物を調製するための計量装置をプログラムする、
工程を含むことができる。
られる準備ができている。下記のように透過率測定を実施後、塗膜をアセトンで除去する。次にMelinexの正方形を再秤量し、元の重量から差し引くことにより、塗膜の重量が決定される。この膜の重量および乾燥塗膜の比重およびサンプルの面積を使用して、膜の厚さが計算される。
を示す。その係数は以下の方法により得ることができるが、前以て決めることができる。
により灰色混合物のクベルカ・ムンク吸収係数Kgを概算することができると推定することができる。実質的に非吸収性の散乱顔料、すなわちTiO2は、400nm未満で強力に吸収性であり(すなわち「黒色」)、そのためカーボンブラックがもはや支配しないために、我々はこの領域を推定することができる。従って、散乱係数Sgは
Sgは非吸収性顔料の1組の波長と容積分率ψnasに対して計算される。各波長においてψnasに対するSgの依存性は3次の多項式に当てはめられた。
.02、0.05および0.07の有色顔料の容積分率、をもつ1組の塗料を与えるために混合される必要がある、非吸収性の散乱顔料(調製は前記に詳述)および有色顔料の質量を計算する。これらの容積分率は、知られているように、または吸収率測定期間中に決定されるように、測定される散乱係数が顔料の容積分率において直線状であることを確保するように選択された。
顔料の特定の混合物を含む塗膜に対する、予測総太陽反射率を、以下の方程式を使用して、300〜2500nm間の10nm間隔で予測された反射率から計算する。
乾燥塗膜内に要する顔料の容積濃度(volume concentrations)から計算される湿潤塗料のすべての成分の質量を含んでなる。この計算は、湿潤塗料および乾燥塗膜中に存在するすべての材料の密度の知識を要する。
