Lignin　isolated　from　enzymatic　hydrolyzed　cornstalks　(EHL)　is　a　renewable　natural　polymer,　and　rubber　is　one　of　the　most　important　polymer　materials.　The　application　of　EHL　in　rubber　industry　is　of　great　significance.　The　influence　of　EHL　and　antioxidant　RD　on　the　vulcanizing　characteristics,　thermal　oxidative　aging　stability　under　free　condition,　and　water　extraction　resistance　of　styrene-butadiene　rubber　(SBR)　were　investigated.　The　effect　of　EHL/antioxidant　D　composite　antioxidant　on　the　thermal　oxidative　ageing　of　SBR　was　also　evaluated.　Results　showed　that　the　protection　of　SBR　from　thermal　oxidative　aging　by　EHL/antioxidant　D　composite　antioxidant　was　superior　to　that　of　antioxidant　D.　This　is　because　EHL　molecules　have　hindered　phenol　group　and　have　excellent　auxiliary　antioxidant　role　with　antioxidant　D.　Moreover,　the　influence　of　EHL　on　the　vulcanizing　characteristics　of　SBR　compounds　was　better　than　that　of　antioxidant　RD,　and　EHL　can　reduce　the　cure　rate　and　increase　the　optimum　cure　time.　It　is　because　that　the　EHL　molecules　have　hindered　phenol　group　and　methoxy　group,　which　can　form　a　special　structure　to　capture　free　radical　and　terminate　the　chain　reaction.　The　retained　tensile　strength　of　SBR　compounds　with　EHL　was　similar　to　that　of　the　samples　with　antioxidant　RD,　while　the　retained　elongation　at　break　of　SBR　compounds　with　EHL　was　higher　than　that　of　the　samples　with　antioxidant　RD.　In　addition,　the　SBR　compounds　with　EHL　have　a　good　water　extraction　resistance　property,　which　was　similar　to　the　samples　with　antioxidant　RD.　This　is　because　EHL　have　large　molecular　weight,　good　stability　and　low　solubility　in　water.　In　conclusion,　due　to　the　low　price,　abundant　resources,　non-toxic　and　pollution-free,　etc.,　EHL　will　have　broad　application　prospect.
