5 results about "Isoflurane" patented technology

The invention provides a polymer framework ink, a polymer framework and cell-loaded gel collaborative 3D printing method and a structural body. The polymer framework ink contains a high-molecular polymer, an organic solvent and organic modified synthetic flaky silicate, wherein the organic solvent comprises a first solvent and a second solvent, the first solvent is an ethanol aqueous solution and / or absolute ethyl alcohol, and the second solvent is methyl acetate and / or isoflurane. The polymer framework ink provided by the invention is rapidly cured through direct volatilization of the organic solvent; the flake silicate is synthesized through organic modification, so that higher fidelity is obtained, and the effect of rapid shaping is achieved while curing is carried out; different sizes of pores in the polymer filaments can be obtained by controlling the temperature difference between the polymer frame ink and the environment; finally, collaborative printing of the polymer framework and the cell-carrying gel can be realized under mild conditions, and the activity of cells is ensured.

The application belongs to the technical field of medicine synthesis, and provides a new preparation method of isoflurane. The method uses hypochlorite and a strong acid as a chlorinating reagent to perform chlorination, which avoids the problems of low conversion rate and excessive chlorination to generate more impurities caused by chlorine gas chlorination. The reaction is more moderate, economical, environment-friendly and high-yield, and is suitable for industrial production.

The environment-friendly flame-retardant rubber has good flame retardance and resilience and is environment-friendly.

This application relates to the field of wiring harness protection materials, and discloses a wiring harness protection material for a new energy vehicle motor controller and its preparation method. The wiring harness protection material for a new energy vehicle motor controller is made by impregnating a base fabric layer with a polyurethane adhesive and then curing it. The polyurethane adhesive is prepared from the following raw materials in parts by weight: 70-80 parts of silane-modified polyurethane prepolymer, 22-28 parts of conductive filler, 4.5-7.5 parts of dispersant, 1-3 parts of antioxidant, 2-4 parts of curing agent, and 80-100 parts of solvent. The silane-modified polyurethane prepolymer is prepared by reacting isoflurane diisocyanate, N-(p-maleimide-phenyl)isocyanate, 3-isocyanatopropyltriethoxysilane, polyether polyol, and a catalyst, with DMF as the solvent. The wiring harness protection material of this application, when applied to a new energy vehicle motor controller, exhibits good electromagnetic shielding stability under long-term high-temperature conditions and good flexibility and bending resistance.
