拉伸模量

According to the double-axis experiment and the uniaxial tension experiment, shear relaxation modulus and bulk relaxation modulus are obtained. Fractional exponent models[23][24][25] are applied to shear relaxation modulus and bulk relaxation modulus. The theory is proved by constant amplitude cyclic strain experiment. Better results are obtained from the comparison of theory curves and experiment results.

The conditions to produce PP-g-PVOH with the highest SP 60% were: ethyl alcohol/butyl alcohol=30/70, NaOH%=0.5%, refluxing at 90℃ for 16hr.FTIR confirmed graft and saponification reactions, and it was identified that graft reaction influence porosity and morphology very little, but microparticles in PP granule were sightly swelled.

Maleic rosin has been added to the surface of wood flour in the form of monoester, i.e., the formation of esterified wood flour bearing a pendent carboxylic group. The rheological study showed that the complex viscosity η(superscript *, storage modulus and loss modulus of WF-HDPE composites decreased firstly and increased afterward and declined lastly as the dosage of maleic rosin increased, however, the viscosity of the composite melts decreased as a whole. After the modification of wood flour, the rheological properties of composite melts were improved markedly. According to the mechanical test it was indicated that, by proper treatment of wood flour with maleic rosin, the tensile strength and flexural strength of WF-HDPE increased obviously.
