Embodiment Construction

[0030] The present invention discloses a non-vacuum preparation method of nano film by using a metal compound as a precursor, which comprises the following steps:

[0031] S1. Prepare a mass fraction of 40% metal particle powder with a particle size of 500-700nm and a mass fraction of 60% metal particle powder with a particle size of 44-48μm into a metal particle liquid with a mass fraction of 30-40%: Put the metal particles into a jet mill for dry grinding for 1-4 hours, with a classification speed of 3500 rpm, ultrasonic cleaning, and drying for 15 minutes to obtain powder metal particles with D50 = 5 μm and D97 = 60 μm, and then classify 5-10 μm powder The powder metal particles are dissolved in 60-70% deionized water with a mass fraction of 60-70% deionized water, ultrasonically stirred, shaken, and separated for 20-30 minutes to obtain a 5-10 μm metal powder solution for later use.

[0032] Parameters of jet mill: The compressed air flow rate in jet mill is 60m / min, the pressu...

Abstract

The invention discloses a method for non-vacuum preparation of a nano thin film by taking a metallic compound as a precursor. The method comprises the steps of S1. preparing a metallic nano mixing solution; S2. preparing a graphite and superconductive carbon black mixing solution; S3. preparing acrylic photosensitive bisphenol A modified epoxy resin; S4. adding a reactive diluent and the like to the acrylic photosensitive bisphenol A modified epoxy resin; S5. continuing adding other materials to the acrylic photosensitive bisphenol A modified epoxy resin; S6. centrifuging; S7. coating; and S8. recoating and curing. According to the preparation method of the metallic compound thin film, which is disclosed by the invention, a non-vacuum precursor 'ink' offset printing spraying method is adopted to spray the precursor on an elastic substrate to form a metallic absorbed layer thin film; by means of a spray conversion method, dosages of raw materials and additive are easily controlled, ingredients, thickness and uniformity of the film can be conveniently controlled, and full use of addition of the superconductive carbon black and graphite can be achieved; the prepared product is low in granularity, high in bulk crystallization density, and capable of effectively improving a forbidden gap.
