Abstract

The invention relates to the technical field of waterproof film coating for intelligent wearable devices, in particular to a preparation method for a nanometer waterproof film for an intelligent wearable device. The method includes the following steps that (1) an intelligent wearable device surface to be coated with a film is cleaned and then dried for 25-30 min with the drying temperature being 20-25 DEG C; (2) the intelligent wearable device to be coated with the film is placed into a vacuum coating chamber, heated and vacuumized; (3) coating raw materials are placed into an evaporation chamber, vacuumizing continues, and the coating raw materials are heated and sublimated; (4) the evaporation chamber is made to communicate with a cracking chamber, and the sublimated coating raw materials enter the cracking chamber to be cracked into active monomers; and (5) the active monomers enter the vacuum coating chamber and are finally deposited on the surface of the intelligent wearable device to form the waterproof film. The waterproof film has the characteristics of being good in waterproof effect, low in coating cost and good in permeability and can conduct good waterproof protection on a product with the quite fine and complex structure.

Description

technical field [0001] The invention relates to the technical field of waterproof coating for smart wearable devices, in particular to a method for preparing a nanometer waterproof film for smart wearable devices. Background technique [0002] Wearable smart devices are a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. [0003] Generalized wearable smart devices include full-featured, large-sized, complete or partial functions without relying on smart wearable devices, such as smart watches or smart glasses, etc., and only focus on a certain type of application functions, which need to be combined with other devices such as smart wearables It is used in conjunction with other devices, such as various smart bracelets and smart jewelry for physical sign monitoring. With the advancement of technology and changes in user needs, the form and application ...
