The invention discloses a method for preparing multifunctional nanometer protection
coating through circulation small-power continuous
discharge, and belongs to the technical field of multifunctional nanometer protection
coating through circulation small-power continuous
discharge. The method comprises the steps that a reaction cavity is vacuumized,
inert gas is introduced into the reaction cavity, a base material moves in the reaction cavity,
monomer steam is introduced into the reaction cavity,
chemical vapor deposition is carried out and comprises a pretreatment stage and a
film coating stage, the
plasma discharge mode is large-power continuous discharge in the pretreatment stage, the
plasma discharge mode is small-power continuous discharge in the
film coating stage, the pretreatment stage and the
film coating stage are cycle and repeated at least one time, more active sites more introduced to the surface of the base material in a circulation mode in the film
coating technological process, effective film coating is added, the
film structure is more compact, the nanometer coating with of the multi-layer
composite structure is obtained, multiple
layers of protection are provided for the product, the more compact coating structure is shown microscopically, and excellent hydrophobicity,
adhesive force, acid and base resistance, mechanical performance and
moisture and
heat resistance are shown macroscopically.
