[0002] With the advancement of science and technology and the development of society, permeable paving materials are playing an increasingly important role in the construction of sponge cities. Since its introduction into China in 2006, permeable paving materials have experienced rapid development and have become an important part of municipal construction, ecological improvement projects and people's livelihood projects. Common permeable paving materials include permeable cement concrete, permeable asphalt concrete, adhesive stone pavement and permeable brick paving. However, after years of use, these materials often become brittle, cracked, and the adhesion of the surface aggregate decreases, resulting in partial stone falling. These problems not only affect the appearance and service life of the road, but also bring certain hidden dangers to traffic safety.

[0003] At present, although permeable paving materials such as permeable cement concrete and permeable asphalt concrete have achieved certain results in practical applications, they still face many challenges in repair and maintenance. Due to the characteristics of the materials themselves and the increase in service life, the repair cost is often high, the repair process is complicated, and the repaired road surface often has a significant color difference from the original road surface, affecting the overall aesthetic coordination.

[0004] Traditional repair methods often require cutting and milling of the damaged area, which not only affects the convenience of traffic in the area, but also increases the difficulty and cost of repair. In addition, the repaired road surface often has obvious color and texture differences from the original road surface, which greatly reduces the overall aesthetics. These problems not only affect the use of the road, but also have an adverse impact on the image construction of the city. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] A method for preparing a colored permeable pavement repair liquid, such as Figure 1 As shown, the AB two components are mixed in a weight ratio of 2:1, wherein the A component is: 35% of polymer modified epoxy resin, 15% of nitrile rubber, 45% of xylene, and 5% of butanol; the B component is: 45% of polyamine, 8% of butanol, 40% of xylene, and 12% of drying regulator; the above preparation method comprises the following steps: at room temperature 25℃±10℃, under stirring conditions, the A component is first added to the reactor 2 under stirring conditions, and the xylene and butanol mixed solution is added while stirring. The nitrile rubber is added and stirred to obtain the A component; the B component is also under stirring conditions, and the polyamine and the drying regulator are added to the stirring reactor 3 under stirring conditions, and the xylene and butanol solutions are introduced while stirring, and the mixture is stirred to obtain the B component; the A and B components are mixed, and the mixture is stirred and mixed to obtain the repair liquid (the rotation speed is 600 rpm).

[0032] Compared with the prior art, polymer modified epoxy resin and nitrile rubber dissolved in xylene and butanol solvents have high boiling point, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion, and stable adhesion at high temperatures of 180-220°C, which can significantly enhance the viscosity between aggregates and improve the overall strength; polyamine is used as a curing agent, and dissolving it in a mixture of xylene and butanol can increase the fluidity of the curing agent, and the drying regulator can reduce the solidification time without affecting the curing effect.

[0033] As a copolymer of polybutadiene and polyacrylonitrile, nitrile rubber has good heat resistance, water resistance (oil, solvent, acid and alkali), and excellent elasticity, which makes it very compatible with epoxy resin. Through the chemical reaction between the active end groups of nitrile rubber and epoxy resin, the flexible chain segments are introduced into the epoxy resin, which has a significant toughening and modification effect on the epoxy resin. This toughening mechanism improves the toughness of epoxy resin cured products while maintaining good heat resistance, thus meeting the requirements of structural bonding.

[0034] The reaction of polyamines with epoxy resins is mainly carried out through ring-opening polymerization. However, the reaction rate is often too fast and the fluidity is poor. By adding a mixture of xylene and butanol to adjust the viscosity and drying speed of the epoxy, the fluidity of the repair fluid can be increased to meet different application requirements. A mixture of xylene and butanol is a commonly used epoxy resin solvent. This mixture can be used to adjust the viscosity and drying speed. The mixed use of xylene and butanol can reduce the cost to a certain extent while maintaining performance and quality. Drying regulators are substances that can accelerate the drying of the coating film and catalyze the oxygen absorption and polymerization of the dry oil film. It significantly shortens the drying time of the coating film by promoting the oxidation and polymerization process of the coating, thereby improving production efficiency.

[0035] like Figure 2 As shown, a production device for colored permeable pavement repair liquid includes a frame 1, a reactor 2 and a stirring tank 3 are arranged on both sides above the frame 1, a mixing barrel 4 is arranged below the frame 1, and the mixing barrel 4 is used for mixing component A and component B. The bottoms of the reactor 2 and the stirring tank 3 are connected to a discharge pipe 502 through a control valve 501, and the other ends of the two discharge pipes 502 are connected to the top of the mixing barrel 4; the reactor 2, the stirring tank 3 and the top of the stirring barrel are all provided with stirring mechanisms for stirring work, and the three groups of stirring mechanisms extend into the reactor 2, the stirring tank 3 and the mixing barrel 4 respectively.

[0036] like Figures 1 to 2 As shown, first, prepare the raw materials of component A (including polymer modified epoxy resin, nitrile rubber, xylene, butanol) and component B (including polyamine, butanol, xylene, and dry regulator) in a certain proportion; add the raw materials of component A to the reaction kettle 2 in sequence, start the stirring mechanism for stirring, and ensure that the raw materials are fully dissolved and evenly mixed; at the same time, add the raw materials of component B to the stirring kettle 3, and also start the stirring mechanism for stirring; when the preparation of components A and B is completed, open the discharge pipe 502 through the control valve 501, and discharge components A and B into the mixing barrel 4 respectively; start the stirring mechanism above the mixing barrel 4 to mix components A and B until the mixture is stirred. until a uniform repair liquid is obtained; the uniformly mixed repair liquid is applied to the colored permeable pavement to be repaired, and the repair liquid is quickly infiltrated and solidified by utilizing its high viscosity, high permeability and high fluidity, thereby enhancing the overall strength and aesthetics of the pavement; through the division of labor and cooperation among the reaction kettle 2, the stirring kettle 3 and the mixing barrel 4, and the precise control of the stirring mechanism, the rapid preparation and mixing of the repair liquid are achieved, thereby improving the work efficiency; through the precise control of the control valve 501 and the stirring mechanism, the accurate mixing of the A component and the B component is ensured, thereby ensuring the quality and performance of the repair liquid; the equipment has a simple structure and is easy to operate, and can prepare the repair liquid in batches, thereby reducing the production cost and the repair cost.

[0037] Preferably, the stirring mechanism includes a stirring motor 601 fixedly arranged on the top of the frame 1, the stirring motor 601 can rotate forward and reverse, the stirring motor 601 is arranged vertically, the output shaft of the stirring motor 601 is fixedly connected with an extension rod 602 downward, and a stirring blade 603 is arranged at the bottom of the extension rod 602; after the motor is started, the extension rod 602 and the stirring blade 603 are driven to rotate through the output shaft, thereby producing a stirring effect. The forward and reverse functions make the stirring more uniform, avoiding the problem of raw material deposition or local uneven mixing.

[0038] like Figure 2 As shown, inner baffles 7 inclined toward the inside of the mixing barrel 4 are provided on both sides of the top of the mixing barrel 4. These inner baffles 7 are not only connected to the discharge pipe 502 to ensure smooth material discharge, but also play a key role. Specifically, the inner baffles 7 are cleverly designed above the stirring blades 603, but slightly lower than the edge of the mixing barrel 4. Such a layout makes it possible for the strong centrifugal force generated when the stirring blades 603 rotate at high speed in the mixing barrel 4 to try to throw the material to the barrel wall. At this time, the inner baffles 7 act as a barrier to effectively block the splashing phenomenon that may be caused by high-speed stirring of the mixed components, ensuring the cleanliness and safety of the production environment; at the same time, this design of the inner baffles 7 also promotes the smooth connection between the mixing barrel 4 and the discharge pipe 502, so that when the repair liquid needs to be discharged, the material can flow out through the discharge pipe 502 without hindrance, further improving the production efficiency and the convenience of operation.

[0039] like Figure 2 As shown, the side walls of the reaction kettle 2, the stirring kettle 3 and the mixing barrel 4 are all made of tempered glass; tempered glass has high strength and corrosion resistance, and can withstand the pressure and chemical reactions that may occur during the preparation process. In addition, tempered glass has good transparency, allowing operators to clearly observe the mixing process, thereby adjusting the stirring speed or mixing ratio in time to ensure the quality of the repair liquid.

[0040] The road repair liquid produced by the production process of Example 1 was tested, and the results shown in Table 1 were obtained.
