Nano-material vacuum coating machine

Abstract

The invention relates to the technical field of nano-material coating equipment, in particular to a nano-material vacuum coating machine which comprises an evaporation furnace for evaporating a coating material into gas, a cracking furnace for cracking the gas, and a coating device for coating a product, wherein the coating device comprises a vacuum furnace, a vacuum pump for evacuating the vacuum furnace and a pressure pump for pressurizing the vacuum furnace, wherein the vacuum furnace is connected with the vacuum pump and the pressure pump through pipelines respectively; the evaporation furnace, the cracking furnace and the vacuum furnace are communicated through a pipeline; a pneumatic valve is further arranged between the cracking furnace and the vacuum furnace. The nano-material vacuum coating machine is simple and compact in structure, strong in sealing property and good in coating effect; a film is unlikely to fall off; and the coating material is nano-material so as to avoid producing harmful gases.

Description

technical field [0001] The invention relates to the technical field of nano-coating equipment, in particular to a nano-material vacuum coating machine. Background technique [0002] Nano-waterproof coating technology is widely used in aerospace military industry, circuit boards, magnetic materials, sensors, silicone rubber, seals, medical equipment, precious cultural relics, small household appliances (soybean milk maker, rice cooker, induction cooker, razor, remote control, Air-conditioning fan, air conditioner, microwave oven, etc., audio), digital (mobile phone, camera, notebook, tablet, earphone,), bathroom, battery, automobile (electronic key, reversing radar, charging pile) and other fields; can be used in gold, silver, tungsten , cobalt, palladium and other metal surfaces form a coating with a thickness of about 2-10nm, so that the metal surface has good wear resistance, waterproof, electrical conductivity, corrosion resistance, high temperature resistance, oxidation ...

AI Technical Summary

Problems solved by technology

[0003] The existing coating machine has the following defects: 1. The air tightness is not strong, which affects the vacuum effect, the vacuuming effect is not good, and the production efficiency is low; and it affects the coating effect, and the yield of the finished product is low; 2. The coating effect is poor, The film is easy to fall off from the product; 3. The equipment mechanism is responsible, and it is inconvenient to maintain; 4. It can only be applied to some metal coating materials, and it is easy to generate harmful gases
