The thermal decomposition for producing asphalt-rubber mixture has reduction pitch

摘要

The technique uses half blown asphalt road asphalt of crude oil and/or crude oil road asphalt, with the part at least 5% weight % of oil content, rubber peels off particle and grain size reaches 10 millimeters, it is 10:1 to 1:5 that first pitch mixes liquid mixture and rubber, which peel off particle mass ratio, and the Mean Speed C/min. R1 (degree) that simultaneously and/or then temperature rises, until realizing maximum temperature Tmax (degree), at 217 and 270 degrees Celsius, thenIt is three-phase (minute) that it, which can be to maintain the temperature and carry out storage duration, and then it cools down Mean Speed C/min. R2 (degree) to temperature lower than 215 degrees Celsius immediately. The value of value R1, R2, Tmax and tp and formula (Tmax-2152directions x (three-phase) x direction (+) Tmax-215-10.5x (R1-1+R2-1)), this formula can from 200 to 1,600 (degree C.min.), while and the temperature more than maintaining be period at most 240 minutes of 215 degrees Celsius.
