Problems solved by technology

Polymer-based nanocomposites have been prepared using reactive extruders, but reactive extrusion technology is a very complicated process, with many factors affecting the results, instability, and complicated preparation methods
Polymer-based nanocomposite modified asphalt is generally prepared by using chemical reagents supplemented by mixers and drying ovens, which can easily pollute the air

Embodiment Construction

[0019] Such as figure 1 Shown:

[0020] The heater 1 has inner and outer layers, and the detection head 3 of the temperature controller 2 is set in the inner and outer spaces of the heater 1; the high-temperature stirrer 4 is fixed on the shelf 5 and connected to the speed controller 6 at the lower end Placed in heater 1; heater 1 is placed in safety explosion-proof incubator 7; temperature controller 2 and speed controller 6 are placed outside of safety explosion-proof incubator 7; one end of condenser tube 8 is connected to safety explosion-proof insulation with glass tube 9 The other end of the opening of the box 7 is connected to the collection bottle 10.

[0021] Placing the heater 1 in the safety explosion-proof incubator 7 can not only prevent the heater 1 from exploding due to overheating, but also maintain a good temperature environment and reduce the influence of the external temperature difference during the preparation process. The detection head 3 is used to sense the...

Abstract

The invention relates to a compound modified asphalt preparation device and a preparation method. The preparation device of the invention is characterized in that a temperature controller is connected with a heater which is arranged in a safe explosion-proof incubator; a speed controller is connected with a high-temperature stirrer, and the lower part of the high-temperature stirrer is arranged in a heater; and one end of a condensation pipe is connected to the safe explosion-proof incubator via a glass pipe, and the other end is connected to a collection bottle. The invention solves the defects of using a common modified asphalt for preparation or using a reaction extruder for preparation in the prior art. The invention can ensure that nano particles and polymer fully disperse in asphaltevenly, so that the processed modified asphalt reaches the technical requirements of Standard Specification for Construction and Acceptance of Highway Asphalt Pavements which is published by the Ministry of Communications. The invention simplifies the complex procedures for preparing polymer-matrix nanocomposite modified asphalt and reduces environment pollution caused by toxic substance in the modified asphalt preparation process; and the softening point of the compound modified asphalt is slightly higher than that of the compound modified asphalt prepared with a high speed shearing method, and low-temperature ductility is greatly improved.

Description

Technical field [0001] The invention relates to a device, in particular to a device and method for preparing composite modified asphalt. Background technique [0002] At present, the main methods for preparing polymer-based nanocomposites include intercalation composite method, in-situ polymerization method, sol-gel method, ultrasonic method, blending method, and chemical dispersant addition method, etc. The equipment and processes involved in these methods Both are more complicated, and the production cost for modified asphalt is relatively high. The production of ordinary modified asphalt is the process of uniformly mixing the modifier and asphalt, usually using high-speed shear and colloid mill. [0003] Before the present invention, the production of ordinary modified asphalt was a process of uniformly mixing the modifier and the asphalt, and high-speed shears and colloid mills were usually used. Polymer-based nanocomposites have been prepared by using a reactive extruder, bu...
