Embodiment 1
[0022] Raw material composition (parts by weight): 65 parts of No. 90 matrix asphalt, 8 parts of SBS modifier, 15 parts of waste aramid fiber, 10 parts of silicon micropowder, 6 parts of rubber powder, 12 parts of polystyrene, and 8 parts of carbon powder.
[0023] Preparation:
[0024] (1) dispense each component according to parts by weight;
[0025] (2) Raise the temperature of the asphalt to 160-170°C, stir continuously at 2000rpm, add SBS modifier to it, and stir for 40-45 minutes;
[0026] (3) Heat up to 180-190°C, add polystyrene into the system, stir for 30-40 minutes, and the rotation speed is 2000rpm;
[0027] (4) Raise the temperature to 190-200°C, add uniformly mixed silicon micropowder, rubber powder and carbon powder into the system, stir and react for 50-60 minutes, and the rotation speed is 2000rpm;
[0028] (5) Cool down to 180-190°C, add waste aramid fibers to the system, stir for 60-70 minutes at a speed of 2000rpm, and pack after cooling down to 120-130°C...

Abstract
The case relates to a road pouring sealant with high corrosion resistance and a preparation method thereof. The raw materials are bitumen, SBS modifier, waste aramid fibers, silicon micropowder, rubber powder, polystyrene and carbon powder according to a specific proportion in parts by weight; the adding order of all the raw materials and temperature and agitation speed in reaction are experimented for multiple times, and an optimal preparation method is determined. The road pouring sealant prepared by the invention has good corrosion resistance, and can greatly decrease the degree of corrosion damage caused by air, water, corrosive materials and the like, and the service life of the pouring sealant filled in cracks is prolonged.
Description
technical field [0001] The invention belongs to the field of highway pavement repair materials, and in particular relates to a road potting glue with strong corrosion resistance and a preparation method thereof. Background technique [0002] Cracks are the main form of early damage to the pavement. In order to prevent water from penetrating into the pavement substructure and causing irreversible damage to the subgrade, the use of crack sealant, that is, potting compound, to fill is one of the commonly used remedial measures. Reasonable use of crack sealant can prevent further deterioration of cracks in the pavement and prolong the service life of the pavement. Among different kinds of crack repairing and filling materials, hot patching asphalt crack sealant is the most common repairing material. It has simple construction and short setting time. Usually, it can be solidified and opened to traffic after 20 minutes of filling the joints, and the price is cheap. Compared with ...
