Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance, and in particular to a two-component penetrating super-adhesive anti-icing coating and a construction process and equipment. Background Art

[0002] Many areas in my country are located in the northern subtropical humid climate zone, with obvious monsoon characteristics. The lowest temperature is in January, and the annual average temperature is between 14.4℃-15.1℃. However, due to the influence of the monsoon, the precipitation variability is large, and there are also differences between the north and south regions. When winter comes, the temperature is slightly lower, and the humid air will cause ice on the road surface, and most of it is black ice and dark ice, which is difficult to detect and can easily cause traffic accidents. Therefore, it is urgent to use corresponding treatment technology for the road surface to deal with the icing of the road surface.

[0003] Anti-icing coating refers to a new type of anti-icing coating that uses water-soluble epoxy resin, wet polyurethane and emulsified asphalt materials as bonding materials, and organic / inorganic coated slow-release materials as anti-icing modifiers and curing agents.

[0004] Water-soluble epoxy resin, wet polyurethane and emulsified asphalt materials are fully mixed in a certain proportion to produce a chemical reaction - cross-linking and curing to harden, forming an island-type polymer material structure with epoxy resin molecules as the continuous phase and asphalt molecules as the dispersed phase. Due to the formation of chemical bonds between the molecular chains during this chemical reaction, a three-dimensional network structure is formed, that is, it is cured into a thermosetting material. After curing, it can be embedded in the road surface to form a network structure with high bonding strength. With the addition of a penetrant, a high-permeability and high-bonding cured layer is obtained. Therefore, its material properties are extremely stable; not only can it no longer melt, but it cannot be dissolved in solvents. It is suitable for various harsh environments such as temperature resistance, wear resistance, insulation, and high voltage resistance. The cured bonding material forms a thin layer of protection on the road surface, blocking the seepage channel of surface water, preventing rainwater from penetrating into the pavement structure and road base, avoiding water damage, and has significant hydrophobicity.

[0005] The main principle of the anti-icing modifier is that under the capillary pressure and vehicle rolling, the internal anti-freezing effect gradually precipitates, thereby lowering the freezing point of water on the road surface and inhibiting snow and ice on the road surface. The anti-icing modifier is a chloride series or acetate series or an organic environmentally friendly green material. The latter two do not contain any chlorides, achieving the effect of no corrosion to road materials and no toxicity to the surrounding environment. Since the anti-icing modifier is coated with organic / inorganic slow-release materials, it can reduce the loss of effective ingredients of the anti-icing modifier that inhibit freezing in the non-icing season, achieving the effect of "no loss in summer and self-melting in winter", thereby ensuring the long-lasting anti-icing effect of the anti-icing coating.

[0006] Based on the above technologies and principles, this application proposes a two-component penetrating super-adhesive anti-icing coating and construction technology and equipment. Summary of the invention

[0064] Highways in high-altitude cold areas: such as sections in the northeast and northwest where the temperature is long-term less than -15℃ in winter.

[0065] Tunnel entrances and exits: To solve the problem of local icing caused by temperature differences, use anti-slip aggregate (corundum).

[0066] Offshore platform deck: resistant to salt spray corrosion and ice load (ice layer is easy to fall off).

[0072] Quick repair: Add microcapsule self-healing agent (such as dicyclopentadiene) to automatically repair construction damage or microcracks.

[0073] The two-component permeable super-adhesive anti-icing coating of this embodiment achieves the following through the two-component, multi-dimensional synergy of the waterborne epoxy-polyurethane interpenetrating network + emulsified asphalt slow-release carrier + acetate anti-icing functional core:

[0074] (1) Long-term anti-icing: Acetate slow release combined with resin barrier, freezing point maintenance period > 5 years;

[0075] (2) Strong and durable: IPN structure makes the tensile strength greater than 8MPa and the elongation at break greater than 150%;

[0076] (3) Construction-friendly: Two-component curing at room temperature, suitable for construction in an environment of -10℃ to 40℃.

[0077] The construction method of the above two-component penetrating super-adhesive anti-icing coating is as follows: Figure 1As shown, the following steps are included:

[0078] S1. Equipment commissioning before construction, commissioning the fine milling car: check the cutter head, install the fine milling module, turn on the equipment, check whether the generator system is normal, commission the hydraulic system, ensure that the fine milling module is flush with the original road surface, and check whether the suction and cleaning equipment are normal; commissioning the anti-icing coating spraying car: turn on the equipment, drain the water in the water tank of the anti-icing coating spraying car, flush the pipeline and nozzle, and check the water spraying of each nozzle during the water spraying process. If it is found that the nozzle is not spraying smoothly, immediately find the cause and solve it to ensure that the nozzle is not blocked, test the aggregate, and check whether the aggregate spreading system is working properly. If not, immediately find the cause and solve it to ensure that the spreading system is safe and normal;

[0079] S2. The construction section is closed and road closure tools are used to close the construction section to ensure that the construction is not disturbed by pedestrians and motor vehicles;

[0080] S3. Fine milling: use fine milling vehicles to quickly process the road surface with fine milling, cleaning and dust collection;

[0081] S4. Clean the road surface. After fine milling, manually clean the remaining stone chips and dust on the road surface again to ensure that the road surface is clean and free of debris;

[0082] S5. Treat minor road surface defects, treat or repair cracks and potholes on the road surface;

[0083] S6. Load the anti-icing coating spray truck. Strictly according to the curing time of component A high-permeability super-viscous anti-icing coating consolidating material, quickly pump component A high-permeability super-viscous anti-icing coating consolidating material into the liquid tank of the anti-icing coating spray truck according to the procedure, and transfer the corresponding amount of component B high-permeability super-viscous anti-icing coating carrier anti-skid material to the collection tank;

[0084] S7. Spread the seal layer, and spread the operation synchronously. Adjust the width of the liquid spraying beam and the aggregate distributor according to the required width. Spread until the material is completely solidified. The spreading amount of component A high-permeability super-viscous anti-icing coating consolidation material is 0.4-0.6kg / m 2 The spreading amount of anti-skid material of component B high-permeability super-adhesive anti-icing coating carrier is 0.3-0.5kg / m 2 ; The construction speed of the anti-icing coating spraying vehicle is 6-8km / h;

[0085] S8. Open to traffic. After the seal layer is spread, wait for at least 3 hours for the road surface seal layer to solidify before opening to traffic. The traffic opening time can be flexibly adjusted according to weather conditions.

[0086] The construction equipment used in the construction method of the two-component penetrating super-adhesive anti-icing coating includes a fine milling car and an anti-icing coating spraying car; the fine milling car is a comprehensive new type of pavement surface treatment car. The fine milling car has the functions of micro-milling, dust removal, cleaning, and surface texture reconstruction. For asphalt concrete pavement, the fine milling car will roughen the aged asphalt residues on the pavement and the polished asphalt pavement to produce a certain micro-texture, making the pavement surface uniformly rough and increasing the interface specific surface area of ​​the original asphalt pavement, so that the A component high-permeability super-adhesive anti-icing coating consolidator and the pavement can better bond. For cement concrete pavement, the fine milling car will roughen the cement concrete pavement as a whole to produce a smooth and rough surface, increase the microstructure of the original cement concrete pavement, and remove the surface slurry and impurities of the cement concrete, so that the A component high-permeability super-adhesive anti-icing coating consolidator and the pavement can be firmly bonded.

[0087] The main technical parameters of fine milling and turning are shown in Table 5:

[0088]

[0089] The key points of fine milling technology include:

[0125] The main technical parameters of the anti-icing coating vehicle are shown in Table 6:

[0126]

[0127] Key points for sealing technology

[0128] (1) Key points for inspection of two-component high-permeability, super-adhesive anti-icing coating vehicles upon arrival

[0131] Check the entire vehicle's air circuit to ensure there are no leaks.

[0132] Check the entire vehicle circuit to ensure that there are no visual abnormalities in the circuit and that various sensors are not loose.

[0133] Start the engine and let it idle for at least 3 minutes. Further check the hydraulic pipelines, gas circuits, and electrical circuits, and check the display screen content to ensure that the liquid consolidating material spreading amount data and formula ratio data are correct; ensure that the solid anti-skid aggregate spreading amount data is correct.

[0134] Lower the spreading mechanism, unfold the liquid material spraying rod, and extend the solid material box to ensure normal operation without obstruction.

[0135] Manually operate the nozzle switch and rotate the fabric roller to check for blockage or obstruction.

[0136] Manually operate the solid material conveying horizontal screw and the material distribution screw to ensure normal rotation without obstruction.

[0137] (2) Key points to note in the construction of two-component high-permeability, super-viscous anti-icing coating vehicles

[0138] Check that the warning lights flash normally.

[0139] Put the batching system, spreading system and sand spreading system in the "automatic" position, press the "start" button, the system starts batching, and when the material level is reached, shift gears and start, finally in the 2nd gear position, ensuring that the driving speed is around 5-7km / h.

[0140] During the spreading process, pay attention to the condition of the road material. If there is serious material or sand breakage, stop the machine in time and deal with the blockage in the nozzle or the spreading box.

[0141] When the liquid material is used up and the material level alarm sounds, stop the machine in time and end the spreading.

[0142] According to the temperature and the time of round-trip feeding, when the temperature is above 25℃ or the round-trip time is 1 hour, after the sealing layer is completed, the water cleaning system must be started in time to clean the dosing pump, valve, spreading pump, nozzle, pipeline, etc. to avoid interruption of the next spreading.

[0143] During the sealing process of each vehicle, the technicians must conduct random inspections on the spraying volume, inform the equipment operators promptly, and make necessary corrections.

[0144] When encountering sudden changes in width, intersections, high-permeability water sections or other special situations during the sealing process, the consolidation material spraying system and the aggregate sand spreading system can be placed in the "manual" position, and the spreading amount or width can be adjusted as required. Press the "start" button and operate manually according to the actual situation.

[0145] (3) Points to note after the construction of the two-component high-permeability super-adhesive anti-icing coating vehicle

[0146] At the end of the road or in special circumstances, when the driver steps on the brakes and slows down to below 3km / h, the control system will automatically shut down (or manually shut down) the spreading system.

[0147] When the consolidating material is used up, the control system will send out an alarm signal. At this time, the operator must press the "start" button again and the spreading system will stop.

[0148] Drain all components through the discharge port. For proportional embedded sealing vehicles, pay attention to recycling and reusing waste materials.
