Design of Rubber composite for Cement Packing

Abstract

The aim of this research is to produce an improved rubber valve by adding reinforced nanoparticles (zinc oxide) used to increase the protection of the rubber valve against tearing and wear and to improve the flexibility and service life of the valve. Nano zinc oxide have been prepared in vitro. Nano zinc oxide were tested for[ X-rays (XRD), Scanning Electron Microscopy (SEM), Chemical Analysis (EDS)].The results showed that zinc oxide produced with a high surface area of less than 100 nm nanoscale, confirmed by scanning electron microscopy (SEM) and X-ray examination (XRD) in addition to 100% purity through the (EDS) test .Zinc oxide nanoparticles were used as fillers in different percentages ofpphr (0.2, 0.6, 0.8, 1 , 1.2) to rubber pastry consisting of (100 %  butyl rubber and 5 % neoprene rubber).In order to ensure that the nanoparticle (zinc oxide) added to the rubber affects the mechanical properties of the rubber, the following test were carried out (hardness).The results showed a decrease in hardness with  increased ratios.The results are sequentially as follows (49 ,49 ,  45.6, 44.8 , 42.4).
