Preparation and properties of organic palygorskite SBR/organic palygorskite compound and asphalt modified with the compound

Microwave irradiation synthesize organic palygorskite has been successfully prepared. FTIR, XDR and morphology analysis indicate that 5 min microwave irradiation of palygorskite (PA) is an appropriate time to improve the structure of PA. PA and organic palygorskite (OP) had marked effect on the high-temperature property of increasing softening point at the content of 1% while SBR had significant effect on the low-temperature properties and improvement of aging resistance with SBR content of 3–4% in SBR/PA and SBR/OP modified asphalts. TG analysis shows that an increase in the size between layers is found. OP has the high mass loss temperature than PA in the presence of SBR. The morphology in accordance with TG analysis indicate that compatibility and storage stability are improved with a homogeneous and stable mix of wavelike structure in modified asphalts.
