Abstract: The natural rubber has good resistance for some acids such as hydrochloric acid. Therefore, natural rubber composites are used in the lining of acid containers. Acid resistance of the natural rubber can be improved by types and levels of fillers. This research studies the effect of silica nanoparticles on acid resistance of natural rubber composites for (37% w/w) hydrochloric acid. Six rubber compounds were prepared with various levels of nano silica of 0, 1, 2, 3, 4, 5 (parts per hundred parts of rubber weight).Tensile properties, hardness (Shore A), compression set, tear resistance and abrasion resistance were tested. Test specimens of tensile properties were immersed in hydrochloric acid for 70 h at room temperature. After immersion, they were dried and tested for determining acid resistance. The acid resistance of rubber composites improved by the addition of nano silica and the best acid resistance of rubber composite was gotten at 3.
