Example Embodiment
[0017] Example 1
[0018] In the embodiment of the present invention, a repair material for quickly repairing road surfaces includes the following raw materials: Portland cement 38kg, fine sand 17kg, vinyl acetate resin 9kg, polyoxyethylene ether 3kg, bran 13kg, and hexamethylenetetramine 15kg.
[0019] Mix the hexamethylenetetramine with 4.5 times the mass of water to prepare the hexamethylenetetramine solution for use. Mix the vinyl acetate resin and the bran, pulverize, heat up to 58°C, heat and stir at this temperature for 20 minutes, then heat up to 76°C, add the hexamethylenetetramine solution, and seal and heat at 76°C and stir for 0.9h. Prepare a mixture. Mix Portland cement, fine sand, and polyoxyethylene ether and stir evenly, then add the mixture and stir for 1.9 hours to obtain the repair material. The stirring temperature when adding the mixture is 50°C.
Example Embodiment
[0020] Example 2
[0021] In the embodiment of the present invention, a repair material for quickly repairing a road surface includes the following raw materials: Portland cement 46kg, fine sand 25kg, vinyl acetate resin 17kg, polyoxyethylene ether 7kg, bran 21kg, hexamethylenetetramine 25kg.
[0022] Mix hexamethylene tetramine with 5 times the mass of water to prepare a hexamethylene tetramine solution for use. The vinyl acetate resin and the bran were mixed and crushed, heated to 62°C, heated and stirred at this temperature for 25min, then heated to 76°C, added the hexamethylenetetramine solution, and sealed and heated at 76°C and stirred for 1h to prepare Get the mixture. Mix Portland cement, fine sand, and polyoxyethylene ether and stir evenly, then add the mixture and stir for 2 hours to obtain the repair material. The stirring temperature when adding the mixture was 55°C.
