The invention discloses an amphiphilic multistage nano SiO2-based masonry cultural relic anti-weathering reinforcing material and a preparation method thereof, and relates to the technical field of cultural relic protection materials. The method comprises the following steps: preparing multi-stage nano SiO2 particles; in a water-paraffin oil two-phase system, a paraffin template is obtained; the exposed side of the SiO2 particles in the paraffin template reacts with an amino silane coupling agent to modify amino groups, then the other side of the paraffin template is modified with alkyl alkoxy silane or organosilicon quaternary ammonium salt, and amphiphilic Janus SiO2 nanoparticles are prepared; and dispersing the prepared amphiphilic Janus SiO2 nanoparticles into an organic solvent according to the mass fraction of 1 to 5 percent, so as to obtain the amphiphilic multistage nano SiO2-based masonry cultural relic anti-weathering reinforcing material. Based on the Janus SiO2 nanoparticles with three-dimensional multi-stage morphology, the anti-weathering agent is used for anti-weathering protection of masonry cultural relics, endows the masonry cultural relics with excellent hydrophobicity, antibacterial activity and surface reinforcing effect, and has excellent durability so as to keep a long-term anti-weathering reinforcing effect.

This utility model relates to the field of casual shoe technology and discloses a highly wear-resistant casual shoe, including a main shoe body. A main shoe sole is fixed to the bottom surface of the main shoe body. The main shoe sole includes an EVA outsole pad, and a frame pad is connected to the top surface of the EVA outsole pad around its perimeter. A bottom groove is formed inside the top surface of the EVA outsole pad, and a midsole pad is adhered to the top surface of the bottom groove. The bottom of this utility model consists of an EVA outsole pad and a TPU anti-slip pad layer. The EVA outsole pad provides rebound and shock absorption, improving wearing comfort, while the TPU material of the TPU anti-slip pad layer itself provides high anti-slip and wear resistance. Its friction and force mainly act on the protruding structures such as the anti-slip heel and anti-slip stripes. When the anti-slip stripes are under force, each group of anti-slip stripes is connected by longitudinal stripes to form a structural rib mesh, reducing the deformation caused by force, thereby ensuring the stability of the bottom anti-slip and wear-resistant structure. At the same time, the use of TPU material ensures high wear resistance.
