Effect Of Filler And Rubber Blending On Properties Of In Situ PB

The properties of carbon black N330 single applied, silica single applied and carbon black with silica applied to in situ PB were studied; the properties of NR/in situ PB, SBR/in situ PB, BR/in situ PB, EPDM/in situ PB were studied.The traits of in situ PB and the possible reasons were studied by test. The results show: in situ PB has a good wet skid resistance; carbon black N330 could improve the properties of in situ PB; when silica was single applied less than 50 phr, the properties of in situ PB was improved while more than 50 phr the compound's properties was lower; when carbon black N330 and silica were applied together to in situ PB, the compound's properties was improved. The blends of NR/in situ PB, BR/in situ PB, EPDM/in situ PB have good properties, while the blend of SBR/in situ PB have low properties.In a word, we can procure compound with good properties by modulate the dosage of filler or blends with NR, BR, EPDM.
