Abstract:The effects of thickener, surfactant, solid content and proportion of pigment on coating color’s extensive viscosity were studied, and the influential mechanism was discussed. The results showed that, the type and the dosage of the thickener had a great influence on coating color’s extensive viscosity; as the dosage of surfactant increased, the extensive viscosity decreased, but the change could be ignored; the solid content of the color increasing could lead to increase of the extensive viscosity and the shear viscosity; as the dosage of clay increased, the shear viscosity increased while the extensive viscosity decreased. |
