Problems solved by technology

Patent 91101620.1 uses the method of electron beam evaporation of solid carbon source to achieve diamond-like carbon film plating on resin materials, but the method is more complicated and the maintenance cost is higher. At the same time, because the used carbon ion beam has a certain directionality, Therefore, the spatial uniformity of the film formation is difficult to guarantee

Embodiment 1

[0035] Deposit carbon film on CR-39 resin white sheet, the specific method is as follows:

[0036] 1. Clean the resin substrate. Use an ultrasonic cleaner to clean the resin substrate, first use acetone as the cleaning agent for 5 minutes, then use deionized water as the cleaning agent, wash for 5 minutes, cut the water with absolute ethanol, and then dry the resin substrate with a hair dryer for later use .

[0037]2. Perform plasma cleaning process. Open the vacuum chamber, put the cleaned resin samples on the lower electrode plate, and put them in the center of the lower electrode plate as much as possible; close the vacuum chamber, start pumping, and turn on the radio frequency power supply at the same time for preheating. When the vacuum degree of the system is stable, argon gas is introduced into the vacuum chamber. When the mass flow controller shows that the flow rate of argon gas is stable, turn on the plate pressure switch of the RF power supply, adjust the RF powe...

Abstract

The invention relates to a method for depositing carbon film on the resin lens, which adopts plasma chemical vapor deposition method to deposit carbon film on the resin lens and uses high frequency electric field provided energetic plasma to do degradation and deposition reaction with the hydrocarbon gas to form the carbon film on the lens surface; the craft course is that it uses ultrasonic cleaning instrument to clean the resin base and uses plasma cleaning craft to clean the base 5min; it puts the hydrocarbon carbon source gas and hydrogen to do the deposition of carbon film wit the radio-frequency energy value 15-400W; the density rate of the hydrocarbon carbon source gas and the H2 gas is 1:(0-3); the deposition vacuum degree is 10-50 Pa; the deposition time is 10s-30min.

Description

technical field [0001] The invention belongs to the technical field of resin material processing, and in particular relates to a method for depositing a carbon film on a resin lens. The carbon film deposited in the present invention belongs to hydrogen-containing amorphous carbon film (a-C:H) or diamond-like carbon film (DLC film). Background technique [0002] In 1955, resin materials began to be used in the production of spectacle lenses. After improvements in technology and materials by scientists, resin lenses became lighter, with stronger light transmission and wear resistance, plus anti-fog and waterproof. The application of film technology has brought more comfort and convenience to consumers. The addition of anti-ultraviolet ingredients to the material also provides an extra layer of protection for the eyes. The tinting of the lenses meets the different needs of consumers of different ages and levels. It is precisely because of the above advantages that people choos...
