The invention discloses a nano-scale insulation board and a manufacturing method thereof. The board body is manufactured by coating a thermal insulation material in a non-woven fabric and packaging the thermal insulation material in a packaging bag in a vacuum seal mode. The thermal insulation material comprises the following raw materials in percentage by weight: 70 to 80 percent of nano-scale fumed silica, 1 to 3 percent of reinforced fiber, 1 to 3 percent of far infrared additive, 12 to 18 percent of silicon carbide, 0.8 to 1.2 percent of drying agent and 5 to 10 percent of adhesive, wherein the heat conductivity coefficient is less than or equal to 0.008W / (m.K). Due to detection, the heat conductivity coefficient of the product is less than 0.008W / (m.K), the heat preservation and heat insulation performances are high, the product is light, the defects that the traditional wall heat preservation building materials have poor fireproof performance, poor heat preservation and heat insulation performances and low crack resistance can be overcome, and the nano-scale insulation board can be widely applied to heat preservation and heat insulation roofs of buildings, outer-wall external thermal insulation and outer-wall internal thermal insulation construction.

The invention discloses a chemistry leakage treatment vehicle. The chemistry leakage treatment vehicle comprises a vehicle body unit, an environment detection unit, and an emergency response unit; the vehicle body unit comprises a wheel group, an accommodating chamber, an opening communicated with the accommodating chamber, and at least one a protection door capable of sealing the opening in an opening manner; the environment detection unit is arranged on the vehicle body unit, and comprises a detection module capable of detecting the environment and sending out a detection signal periodically, a processing module capable of receiving the detection signal and sending out a processing signal, and a response module capable of receiving the processing signal and sending out a response signal; the emergency response unit is arranged on the vehicle body unit and comprises a water storage tank, at least one water spray nozzle, and a driving module capable of spraying a content in the water storage tank via the water spray nozzle. The chemistry leakage treatment vehicle can be not only used for storing tools and instruments, but also possesses shielding, environment detection, alarming, and emergency fire controlling functions.

The invention provides a method for preparing amorphous and nanocrystalline improved polyester self-cleaning shielding fibers, which mainly includes selecting polyester chips with good spinnability as spinning substrates, and selecting amorphous and nanocrystalline nano functional powders as functional additives, wherein the functional The additives are selected from CNTs (mass fraction 0.05%~8%) that can improve electrical conductivity and mechanical properties, one or all of magnetic nanoparticles FeCo, Fe3O4 (0.05%~12%), spinning matrix and functional Additive blending, melt spinning and other processes. The fiber obtained by the invention can achieve the uniform dispersion and spinnability of the nano-additive, and at the same time has the synergistic effect of improving the mechanical properties, increasing the antibacterial properties and electromagnetic shielding properties of the polyester polyester.
