Preparation and Properties of High Color Stable Red PA6 Material
Red nylon 6(PA6)material was prepared by twin screw extruder,the effects of various red pigments and plasticizers on the comprehensive properties of PA6 material during moisture absorption were studied by means of universal testing machine,impact testing machine,spectrophotometer and electronic balance.The results show that the hygroscopicity of red PA6 material changes seriously,and red pigment has little effect on the hygroscopicity of PA6 material.The hygroscopicity and color change direction of red PA6 material with different red pigments are different.The combination of organic red 178 and solvent red 52 improves the moisture absorption and discoloration of red PA6 material.The more plasticizer is used,the better effect of moisture absorption and color change of red PA6 material is.With the addition of plasticizer,the rigidity of red PA6 material decreases,the toughness increases and the moisture absorption decreases slightly.
