Asphalt No. 30 | Asphalt drilling fluid treatment agent | Oxidized asphaltQingzhou Tianyi Chemical Co., Ltd

In the past two years, the concept of mixed modified blue coating has attracted great attention. Asphalt drilling fluid treatment agents usually refer to the use of two or more modifiers to modify the main asphalt to obtain a superior combination of high temperature and low temperature, usually SBS and natural asphalt to modify petroleum asphalt.

Experiments have shown that a reasonable ratio of SBS to stone asphalt can achieve a softening point of over 70 ℃ for modified asphalt injection at level 30 (this is a typical level 30 asphalt, and natural modified asphalt cannot reach the height of the softening point).

In addition, this combination modified asphalt has good low-temperature delay function. All samples of asphalt drilling fluid treatment agents can meet the technical requirements of JTG F40 № 30 asphalt. Even after short-term aging, it can still maintain a certain 5 ° C delay and excellent 10 ° C delay, which is the delay effect. This is something that cannot be reached by 30 asphalt and natural asphalt modified asphalt.

Correspondingly, the PG functional grade of this composite modified asphalt has also been comprehensively improved, with a high temperature grade of over 82 ℃ and a low temperature grade of -16 ℃. Compared with general No. 30 asphalt and natural modified asphalt, it has better overall high temperature and low temperature functions.
