Improved mechanical properties of silica reinforced rubber

DPG (1.3-diphenylguanidine) in Fig. 2 is often used in silica reinforced rubber composites to increase curing speed. Fig. 2 shows that DPG significantly increased the curing speed in silane coated silica composite. However, DPG is a toxic chemical and is preferred to be replaced with non-toxic agents.

In a step-wise approach it is shown that the presence of silica influences both devulcanization and revulcanization. The best tensile strength of the revulcanizate, using a carbon-black-based revulcanization formulation, was 5 MPa. This could be improved to 6.5 MPa by using 2.8 phr of 1,3-DiPhenylGuanidine (DPG) in the revulcanization formulation.

Marching modulus phenomena are often observed in silica-reinforced solution styrene–butadiene rubber/butadiene rubber (S-SBR/BR) tire tread compounds. When such a situation happens, it is difficult to determine the optimum curing time, and as a consequence the physical properties of the rubber vulcanizates may vary. Previous studies have demonstrated that the curing behavior of silica

Recently, the effect of silanization accelerators such as amines, enamines (-RC=C-NR2) and aldimines (R-CH=N-R) has been studied.[74,75] In these studies it has been experimentally demonstrated that the use of these amines in combination with DPG (1,3-diphenylguanidine) significantly improves the degree of silanization. In addition, DPG itself
