抄録

As reinforcing agents, carbon black, white carbon, etc. are used in rubber industry. However, carbon black makes impossible to color the rubber stock freely. While white carbon is not enough to reinforce the stock.<br>For the purpose of improving these faults, some reinforcing agents were prepared principally from urea resin. The agents were loaded into NR, SBR and NBR. After valcanization, the results of reinforcement were observed.<br>Varying the condition for preparation, some kinds of urea were prepared. And other sorts were obtained adding some resins, such as acrylamide, melamine or cpoxy resin, to the urea resin. From the values of tensile strength, elongation, modulus, hardness etc. of the valcanizatess, the effectiveness of the resin reinforcing agents were estimated.<br>In conclusion, it was found that the urea resin blended with acrylamide was almost satisfactory.
