The Properties of PVC/Urea-Formaldehyde Modified EHL Composite
Composite of PVC with enzymatic hydrolysis lignin( PVC/EHL) was prepared. The influences of EHL and urea-formaldehyde modified EHL on the properties of the composites were studied. The results showed that the tensile strength and the impact strength of PVC/EHL decreased with the increasing of EHL content in the composite. After modification, the compatibility between PVC and EHL was ameliorated. And the mechanical properties of the composite were improved. The addition of EHL and urea-formaldehyde modified EHL both increased the Vicat softening temperature of the composites.
