The Effect of Rubber Recycles Variation as A Non-reinforcing Filler on Functional Group, Microscopic Structure and Mechanical Properties

摘要

One of the various rubber product problems is rubber recycle disposal management due to rubber material is not decomposed easily so that recycle disposal leads to an environmental pollution. In this context, recycle recycling research is carried out by mechanical degradation. Reusing recycle in formulation as a filling material and varied by 0.0; 7.5; 15.0; 22.5; 30.0; 37 phr of rubber weight. Compounds with a variety of rubber recycle products will be vulcanized. The vulcanization result will be tested for properties of functional group, microscopic structure and mechanical, involving hardness, specific gravity, abrasion resistance, tensile strength, elongation at break and tear strength of vulcanized rubber. Based on the results of tests that have been carried out, several findings as follows are: the mechanical properties obtained in formulas I, II, III and IV still meet these requirements while formulas V and VI values are under the quality requirements, the addition of various rubber recycle does not show changes in functional groups contained in vulcanization activity but peak intensity of the sample that has been combined with rubber recycle is higher, especially the peak at the wavelength of 1552 cm~(-1) associated with C-O-C vibration, and variation of rubber recycle show that the smaller size of rubber recycle is more dispersed and visible.
