A high-performance epoxy asphalt concrete main material for roads and bridges with the characteristics of low temperature resistance and the like belongs to the technical field of new chemical materials for roads and bridges.

Background technique

The application of epoxy asphalt in road and bridge has a long history. Since the main component of petroleum asphalt in epoxy asphalt is a mixture of aliphatic hydrocarbons and aromatic hydrocarbons, its solubility parameter is about 8.66, while the solubility parameter of epoxy resin is 10.36, so the mixed system is difficult to be compatible in thermodynamics and become uniform stable system. In order to effectively prepare epoxy asphalt materials, four processes are generally used to prepare epoxy asphalt materials: co-solvent, modified asphalt, special epoxy resin and modified curing agent. For example, in 1961, Thomas E.Mika of Shell Corporation used pine tar as a co-solvent for epoxy resin and asphalt, and used diethylenetriamine and phthalic anhydride as curing agents to successfully prepare epoxy asphalt bonding materials. , and applied to the concrete surface and roadbed, the disadvantage is that pine tar remains in the system as a solvent, which has a great impact on the long-term performance stability of the material; Hijikata et al. synthesized two active co-solvents, and at the same time The use of phenols (such as nonylphenol, etc.) as a co-solvent was discussed, and it was found that when 10 parts of nonylphenol was used as a co-solvent, the product was easily separated from the asphalt, and when the nonylphenol was increased to 40 parts, the bending strength of the material In addition, by maleic anhydride modification of asphalt, it can also make it have good compatibility with epoxy resin, such as Shigeyuki Hayashi, etc. using a small amount of maleic anhydride (5%, 10%) or maleic anhydride The acid anhydride ester modified asphalt at high temperature, and found that the obtained asphalt has good compatibility with epoxy resin. When polyamide with an amine value of 315 is used as the curing agent, the maximum tensile strength of the obtained material is It is 2.1MPa, and the elongation rate is 60%. Using modified curing agent is also a new way to prepare epoxy asphalt.

This technology uses ordinary matrix asphalt as the main material, and the source of raw materials is wide and the price is low. Compared with the tetramethylphthalic anhydride used in the above patents as the main curing agent of the material, this technology uses long-chain aliphatic dibasic acid or acid anhydride as the main curing agent. On the one hand, its longer non-polar chain can form a flexible bridge structure between asphalt and epoxy resin, and the reactive active functional groups at both ends of the long chain can react with polar epoxy resin , to form a stronger and stronger molecular bond force, which can more effectively increase the compatibility between asphalt and epoxy resin, and on the other hand, it can avoid the use of tetramethylphthalic anhydride to cure the material at low temperature. brittleness; using polyanhydride as a ligand curing agent, its longer molecular chain can effectively increase the flexibility of the material at low temperature; no dispersant such as kerosene is added to the material of this technology, which can ensure that the material will not be damaged during long-term use. Substances are precipitated to increase the effective use time; this technical material can also be equipped with an appropriate curing accelerator to make the material's operable time more variable to meet a wider range of application requirements.

Compared with the above patented technology, this technical method is simple and easy to implement. During the preparation, each of Part A can be directly added to a common reactor and other mixers for mixing, avoiding the A part mentioned in the above patent. The components in the part need to be added in batches, and high-speed dispersion in a special colloid mill is used. Partial reactions even require the complex operation of nitrogen protection reaction or reflux of condensed water for several hours, so that the process control in the production process is simple and the equipment Occupancy is small, the product performance is stable, and the output can be greatly increased, the production cost is low, and it can meet the demand for larger use.

Under the construction condition of 121°C, the operating time for the viscosity to reach 1000cp is 63-84min, the choice of operating time is more extensive; the average Marshall stability can reach 70KN, and the dynamic stability is as high as 310,000 times/mm, showing excellent anti-rutting performance; After standing for 24 hours, the material showed ductile fracture when splitting, showing the excellent low temperature resistance of this material.

The tensile test is used to evaluate the strength and fracture deformation capacity of epoxy asphalt materials. The test standard is ASTMD638. The test steps are: prepare the tensile test piece according to the test requirements, and then clamp the two ends of the test piece on the tensile testing machine. Separate at a constant speed of 500mm/min until it breaks, and the test temperature is 23°C.
