A photothermal low temperature anti-icing film

Abstract

The invention relates to a photo-thermal low-temperature anti-icing pasting pad. The pasting pad comprises a functional film layer and a viscose layer, wherein the functional film layer comprises a base film, a photo-thermal layer, a self-repairing super-hydrophobic layer and a silver nanowire layer; the photo-thermal layer is arranged on the base film, the self-repairing super-hydrophobic layer is arranged on the photo-thermal layer, and the silver nanowire layer is arranged on the self-repairing super-hydrophobic layer. According to the photo-thermal low-temperature anti-icing pasting pad, the anti-freezing protection of outdoor running equipment and instruments can be realized, and the rapid deicing of the surface after the attacking of ice, snow and freezing rain can be realized.

Description

technical field [0001] The invention relates to the field of protective films, in particular to a photothermal low-temperature anti-icing film. Background technique [0002] Icing is a common natural phenomenon, especially in low-temperature and high-humidity areas, when water vapor in the air comes into contact with the surface of a material whose temperature is lower than the freezing point, it will undergo a phase change to form frost, and ice and snow disasters such as freezing rain and frost and snow are also likely to cause Icing, icing causes a lot of inconvenience and loss to people's production and life. For example, icing of refrigeration equipment will cause the heat transfer efficiency of the equipment to decrease or even fail. Icing will also cause some outdoor special equipment and precision instruments to fail. The icing will also greatly damage the ecological environment, transportation, power facilities, etc. [0003] There are two main categories of curren...

[0002] Icing is a common natural phenomenon, especially in low-temperature and high-humidity areas. When water vapor in the air touches the surface of a material whose temperature is lower than the freezing point, it will undergo a phase change and form frost. Freezing rain, frost and snow and other ice and snow disasters are also likely to cause Icing, icing causes a lot of inconvenience and loss to people's production and life, such as icing of refrigeration equipment will reduce the heat transfer efficiency of the equipment or even fail, and icing will also cause some outdoor special equipment, precision instruments, etc. to malfunction, seriously The icing will also greatly damage the ecological environment, transportation, power facilities, etc.

[0003] There are two main categories of current anti-icing technologies. The first category is active methods, including mechanical deicing, electric heating, and photothermal deicing. The equipment still needs to be improved; the second type is the passive method, using hydrophobic anti-icing materials, etc., but the low surface energy substances on the surface of hydrophobic materials are easy to degrade under environmental stimulation. On the other hand, the surface structure of hydrophobic materials is easy to be damaged by mechanical friction or Damaged by scratching, these damages will cause the hydrophobic material to lose its hydrophobic properties
