Abstract

This study aimed to improve the performance of a masterbatches by improving the latex compounding process. Four types of methods for preparation of natural rubber latex/silica composites are performed. In particular, atomization combined with high-temperature sputtering (A-HTS) method which is developed to optimize filler dispersion of latex compounding technology is conducted to dry the masterbatches. Comparison of experimental data on four methods shows that the average tensile strength of A-HTS was 30.07 MPa, that of Strong acid flocculation was 25.87 MPa, that of natural drying was 25.84 MPa, and that of ribbed smoked-sheet general mixing was 20.28 MPa. Compared with the conventional mixing method, A-HTS increased the tensile strength by 33%. The A-HTS technology also has advantages in rolling resistance and wet-skid resistance. Filler dispersion of rubber compounds prepared by A-HTS technology performs better than the other three methods which discussed in this article.
