This application discloses a high-temperature carbonized expandable gel foam and its preparation method, belonging to the field of fire prevention and extinguishing technology. The gel foam consists of 1-10% by mass of an expandable flame-retardant system, 0.81% by mass of a foaming system, 1.385% by mass of a gel system, and deionized water.

The gas source decomposes and produces gas, driving the skeleton to expand into a dense carbon layer, achieving oxygen and heat insulation. This gel foam rapidly covers the coal body at room temperature to isolate oxygen, and expands and retards at high temperatures, achieving the effect of inhibiting spontaneous combustion of coal.

This invention discloses a traditional Chinese medicine paste composition for nourishing qi and blood, warming the meridians, and beautifying the complexion, and its preparation method.

This invention relates to the field of biomedical materials technology, specifically to a decellularized matrix microparticle (dECM-MPs) 3D printing ink and its preparation method. The key technical points are: a heat-absorbing compound is temporarily dissolved on the surface of decellularized matrix microparticles (dECM-MPs) via recrystallization from a supersaturated solution; then, the microparticles are immersed in a temperature-sensitive gelatin solution. The heat absorbed during the dissolution of the heat-absorbing compound leads to a localized low temperature around the microspheres, causing the gelatin to solidify on the dECM-MPs surface, forming a physically cured gelatin hydrogel microlayer in situ. This microlayer is further stabilized by enzymatic cross-linking. Photosensitive modified hyaluronic acid molecules are introduced into the hydrogel microlayer to regulate its mechanical properties. Centrifugation yields a particulate ink suitable for extrusion 3D printing. After 3D printing, ultraviolet light irradiation is used to produce a 3D printed implant. This invention overcomes the problem that rigid dECM-MPs, such as decellularized cartilage microparticles or decellularized bone microparticles, cannot be extruded and printed. By regulating the mechanical properties of the hydrogel microlayer, particulate ink with excellent printing performance can be obtained. This method overcomes the limitation of rigid tissues being difficult to additively manufacture.
