The invention relates to a chrome-free tanning leather retanning agent which is based on hydrogen bond self-assembly and contains (methyl) acrylic resin and triblock non-ionic type parent polyurethane resin and a preparing method of the chrome-free tanning leather retanning agent. The retanning agent is characterized in that hydrogen bond assembly units of the retanning agent are the (methyl) acrylic resin and the triblock non-ionic type parent polyurethane resin, the assembly units are made of traditional leather retanning materials widely applied, and the application effect of the traditional leather retanning materials is generally accepted. Due to the fact that the hydrogen bond assembly effect of the assembly units is enhanced along with reducing of pH values, appropriate molecular structures are selected to enable a system to carry out assembling and settling at the needed pH value and are selectively arranged between leather collagen fibers in a filling mode, and physical and mechanical properties of the chrome-free tanning leather are close to those obtained after retanning is carried out on the chrome tanning leather and good soft fullness, good hand feeling and the like are endowed to the chrome-free tanning leather. The method can be used in cooperation with the novel chrome-free tanning technology, seamless conversion from a traditional chrome tanning leather retanning system to a clean chrome-free tanning retanning system is achieved, and the method is hopeful to become an important part of the tanning cleaning technology.

The invention relates to an asphalt mixing material performance enhancing agent and a preparation method thereof, and belongs to the technical field of road materials.
