Background
The ethylene propylene rubber is rubber with a molecular main chain having saturability, and has excellent aging resistance, weather resistance and other properties. The synthetic rubber is composed of ethylene and propylene as main monomers, and is divided into ethylene propylene rubber and ethylene propylene diene rubber according to different monomer compositions in a molecular chain, wherein the former is a copolymer of ethylene and propylene, and the latter is ethylene. They are commonly referred to as ethylene propylene rubbers and are widely used in automobile parts, waterproof materials for buildings, wire and cable sheaths, heat-resistant hoses, tapes, automobile seals, lubricant additives and other products.
The self-cleaning effect of the hydrophobic surface similar to lotus leaf is a hot point of research in recent years due to its wide use value. The hydrophobic surface has special wettability, water drops have good geometric appearance on the surface and cannot be wetted, and when the water drops do not wet, impurities on the surface of solid such as dust and the like can be taken away through self rolling, so that the self-cleaning effect is achieved. The hydrophobic property of the material is enhanced by adding other materials into the ethylene propylene rubber, so that the improvement of the self-cleaning property of the material also becomes a popular direction for the research of the ethylene propylene rubber.
