[0035] Preparation of Toughened Waterborne Epoxy Resin Emulsion D:

[0036] 1) Weigh 85 molar parts of bisphenol A epoxy resin E51 and 15 molar parts of polypropylene glycol diglycidyl ether into a four-neck flask, protect with nitrogen, stir at 85°C for 10 minutes, then add 100 molar parts part of polyethylene glycol 6000, and continue stirring at 85°C for 30 minutes to make it a uniform and transparent colorless solution;

[0037] 2) Accurately weigh 1 part of anhydrous aluminum trichloride in molar amount, quickly add it into the above reaction vessel, keep the temperature at 85°C, and stir for 4 hours;

[0038] 3) After the reaction is over, take out the four-necked flask to obtain the toughened water-based epoxy emulsifier C;

[0039] 4) Weigh 10 parts by mass of toughened water-based epoxy emulsifier C and add it to a three-necked flask, add 80 parts by mass of bisphenol A epoxy resin E51 to the above-mentioned three-necked flask, and stir at 70°C for 30min until Mix t...

Embodiment 1

[0048] 1) Mix 800g of cationic emulsified asphalt with a solid content of 65% and 200g of toughened water-based epoxy resin emulsion D, and then mechanically stir for 30min at a temperature of 30°C;

[0049] 2) Add 600 g of water dropwise to the above mixture at a rate of 1 g / min, and continue stirring for 30 min after the dropwise addition to obtain component A of the fog seal layer.

[0050] Weigh 200g of toughened water-based epoxy resin curing agent E with a solid content of 50%, add 300g of water and mix it evenly to obtain component B of the fog seal layer.

[0051] Weigh 400g of component A of the mist seal layer, 125g of component B of the mist seal layer, and 0.5g of the plasticizer fumaric acid PB. After mixing evenly, use a high-pressure spray gun to spray on the surface of five 300×300×50mm rut plates, and then Evenly spread 52.5g of 40-60 mesh corundum on its surface. Wait for the surface geodesic to dry before testing, which generally takes 8 to 12 hours.

Embodiment 2

[0054] 1) Mix 600g of cationic emulsified asphalt with a solid content of 65% and 400g of toughened water-based epoxy resin emulsion D, and then mechanically stir for 30min at a temperature of 30°C;

[0055] 2) Add 800 g of water dropwise to the above mixed solution at a rate of 1 g / min, and continue stirring for 30 min after the dropwise addition to obtain component A of the mist seal layer.

[0056] Weigh 400g of toughened water-based epoxy resin curing agent E with a solid content of 50%, add 600g of water and mix it evenly to obtain component B of the fog seal layer.

[0057] Weigh 600g of component A of the fog seal layer, 333g of component B of the fog seal layer, and 0.5g of plasticizer DBP. After mixing evenly, use a high-pressure spray gun to spray on the surface of 9 pieces of 300×300×50mm rutting plates, and then evenly Sprinkle 93.3g of 40-60 mesh corundum, and wait until the surface is geodesic and dry before testing, which generally takes 8-12 hours.

Abstract

The invention belongs to the technical field of road repair, and particularly relates to an embedded antiskid waterproof fog seal and a preparation method thereof. The preparation method is as follows: cationic emulsified asphalt and toughening waterborne epoxy resin emulsion are mixed according to a certain proportion, so that a fog seal component A is prepared, a toughening waterborne epoxy resin curing agent is diluted by water to certain viscosity, so that a fog seal component B is prepared, the A and the B are then mixed according to a certain proportion and then sprayed onto a milled pavement, moreover, a certain amount of silicon carbide of specific meshes is sprinkled on the surface of the pavement, and normally after one to three times of repeated construction, an optimal effect can be achieved. Compared with the prior art, the embedded antiskid waterproof fog seal disclosed by the invention has good waterproofness, good wear resistance and certain toughness, and can have longer waterproofness.

Description

technical field [0001] The invention belongs to the technical field of road restoration, and in particular relates to an embedded anti-skid and waterproof fog seal layer and a preparation method thereof. Background technique [0002] Most of the domestic high-grade highways have been built for nearly 20 to 30 years, and they are still being vigorously built. Due to the many deficiencies in the construction technology and materials used in the early high-grade highways compared with the present, many high-grade highways that have been built at present have various degrees of cracking, friction drop, roadbed seepage deformation and other diseases, which have also seriously affected the Road traffic safety and road traffic efficiency. [0003] At present, the early maintenance methods of asphalt pavement are mainly based on microsurfacing or slurry seal. The micro-surfacing is more used for repair and maintenance when there are more obvious cracks and more serious diseases on...
