| titleOfInvention | Temperature-sensitive purification material for reducing formaldehyde pollution risk in vehicle and preparation method thereof |
| abstract | The invention discloses a temperature-sensitive purification material for reducing formaldehyde pollution risk in a vehicle and a preparation method thereof, wherein the preparation method comprises the following steps: step one, weighing an emulsifier, adding the emulsifier into deionized water, and fully stirring for 6-12 hours at 80-100 ℃ for emulsification and dispersion to obtain a mixed system A; step two, respectively weighing the slow release carrier and the slow release core according to the formula proportion, simultaneously adding the slow release carrier and the slow release core into the mixed system A, stirring for 2-4 h, and fully mixing and dispersing to obtain a mixed system B; transferring the mixed system B to a vacuum freeze dryer, and freeze-drying for 24-48 h at-40 to-20 ℃ to obtain a freeze-dried material C; and step four, fully washing the freeze-dried material C by using absolute ethyl alcohol, and removing the residual slow-release core body on the surface of the freeze-dried material to obtain the temperature-sensitive purification material. The formaldehyde purification efficiency of the material is gradually improved along with the rise of the temperature, and the temperature-sensitive phase-change material with the temperature of 20-35 ℃ is preferably selected, so that the material meets the long-acting treatment requirement of the formaldehyde in the environment in the vehicle, and has higher social benefit and economic benefit. |
