Abstract

The invention discloses a device and a synthetic method for producing modified asphalt. The device comprises a mixing device provided with a raw material inlet, wherein the mixing device is communicated with a heat insulation tower; the heat insulation tower is provided with a mixture inlet and a discharge hole, the mixture inlet is formed on the lower part of the heat insulation tower, and the discharge hole is formed on the upper part of the heat insulation tower; and matrix asphalt and modifier are fully mixed and delivered to the heat insulation tower for synthesizing, fluid flows through gaps of shell and tube heat exchangers from bottom to top to exchange heat in a large area, and the mixture follows rise of the fluid level and relative motion of the shell and tube heat exchangers, so that the flowability of the mixture is ensured, and the mixture is heated more uniformly and fully.

Description

technical field

[0001] The invention relates to a mixing and heating device, in particular to a device for producing modified asphalt using base asphalt and a modifier as raw materials and a synthesis method for producing modified asphalt using the device. Background technique

[0002] The sediment produced in the oil refining process is collectively referred to as petroleum base asphalt or base asphalt. Base asphalt is a binder for flexible pavement construction. It has good cohesiveness, impermeability, insulation and chemical stability. It is Commonly used road construction materials. Due to the temperature sensitivity of the base asphalt, its rigidity and strength decrease at high temperatures, and the pavement softens, while at low temperatures, it is easy to produce shrinkage cracks and other pavement cracking phenomena. It is necessary to add modifiers to the base asphalt to modify it to improve its performance. Mechanical properties at high and low temperatures. Th...
