The invention is suitable for the technical field of materials, and discloses silica gel and a preparation method thereof, and a silica gel product and a preparation method thereof. Wherein the silica gel comprises a first component and a second component, the first component comprises a base material, a reinforcing agent, a modified filler, titanium dioxide and a vulcanizing agent, and the second component comprises a base material, a reinforcing agent, a modified filler, titanium dioxide, a cross-linking agent and a polymerization inhibitor. The silica gel provided by the invention not only has better mechanical properties, but also has a small friction coefficient, when the silica gel is in contact with skin, the adhesion feeling is low, the smooth effect is good, and the smooth feeling and the skin-friendly property are improved. Moreover, two components, namely the first component and the second component, are arranged, the first component and the second component are stored separately, the material is easy to store and stable in performance, the service life of the product can be prolonged, in addition, the material preparation and forming process is simple, the vulcanization time is short, and the production efficiency is greatly improved.

This invention provides an iliac vein stent and its system. The iliac vein stent includes a main stent, an embedded branch, and a second branch. The main stent includes a main body and a first branch connected to the distal end of the main body. The embedded branch is folded and shaped and then placed within the main body, with a portion of its outer wall fixedly connected to the inner wall of the main stent. Compared to its natural state, the minimum distance between the embedded branch and the center of the main body is increased in the folded and shaped state. The second branch is embedded in the embedded branch and connected to the main stent. Because the embedded branch is folded and shaped and placed within the main body, the elastic recovery force of the embedded branch in the folded and shaped state is small or even negligible. When the compressed iliac vein stent is located within the sheath, the compressive and frictional forces between the embedded branch and the inner sheath core are reduced, effectively mitigating damage to the embedded branch from the inner sheath core.
