Problems solved by technology

[0002] With the continuous improvement of people's living standards, automobiles are also becoming longer and longer, and the damage to the road surface is also increasing. Therefore, the road maintenance department must often repair the cracks and potholes on the road surface in time, but the currently used sealant There are the following problems: (1) the formula is relatively complicated; (2) the high temperature stability and aging resistance are poor, and it is easy to become brittle and crack when the temperature is low in winter, and it is not suitable for cold temperature difference areas. The adhesiveness of the road surface is not good, and it will move outward in summer; (3) when the temperature is below zero, the joint filler needs to be heated before it can be used, which causes troubles for the road maintenance department in the process of maintenance and use, and wastes manpower and material resources
