Abstract
Polymer chains are reinforced by the addition of suitable reinforcement materials to improve performance properties such as mechanical, physical and chemical properties. Presents research include experimental test such as specific gravity, rheological and flexing test were used to evaluate several rubber recipes contain natural and synthetic rubber. The reinforcing materials such as silica and carbon black were also used to enhance the bonding of the rubber chains. N, N-dicyclohexyl-2-benzothiazole-sulfonamide, N-cyclohexyl-2-benzothiazyl sulphenamide and (N-oxydiethylene-2-benzothiazole sulfenamide were used in addition two types of vulcanization system. The experimental and theoretical results were evaluated and compared with the results of the standard recipe that currently used to produce the rubbery part of flexo-pump system and showed that the increasing in the reinforcing material loading led to increasing the specific gravity, also the increasing in natural rubber loading led to increase the flexing resistance. Moreover, the use of specific grade of black carbon (such as N330) causes the similar improvement while the use of silica in specific quantities (50% of carbon black) gives different effects for all attempts. Some of new recipes gave excellent results comparing with the standard recipe. Some recipes were the safest because they have the highest scorch time ts2 while other recipe probably considered is the most economical because it has the lowest curing time ts90.
