preparation example Construction

[0042] A preparation method of a cleaning agent for an anti-sticking plate of OLED organic evaporation equipment, comprising:

[0043] According to the parts by weight in claim 2, various components are added into the stirred tank successively, wherein the stirring speed is controlled at 30 ~ 50 rpm, cooling water is used in the jacket of the stirred tank, and the temperature is controlled below 40 degrees. The cleaning agent was prepared after stirring slowly at room temperature for 30 minutes.

[0044] Application of a cleaning agent for the anti-sticking board of OLED organic evaporation equipment. Under the condition of temperature 40-60°C, soak the anti-sticking board of organic evaporation equipment in the cleaning agent for 30-60 minutes to remove the surface of the anti-sticking board organic pollutants; the temperature is 50°C; the soaking time is 60min.

Embodiment

[0046] Take 55kg of N-methylpyrrolidone, 15kg of N,N-dimethylformamide, 5kg of monoethanolamine, 15kg of ethyl acetate, and 10kg of dimethyl sulfone, and add them to the stirring tank in sequence, wherein the stirring speed is controlled at 30 rpm, stirring Cooling water is used in the kettle jacket, the temperature is controlled below 40 degrees, and the cleaning agent is prepared after stirring slowly at room temperature for 30 minutes.

[0047] Under the condition of 60°C, use the cleaning agent of the above ingredients to soak the anti-sticking plate of the evaporation equipment for 60 minutes, so that the organic pollutants are completely removed. Observation by the microscopic ultraviolet lamp shows that there are no visible pollutants on the surface.

Abstract

The invention provides an OLED organic vacuum evaporation equipment anti-adhesion plate cleaning agent and applications thereof, wherein the ratio, the production and the applications of the cleaningagent are provided. A purpose of the invention is to overcome the defects of the existing cleaning technology, wherein the defects are that a lot of residual organic matters (visible through a microscope ultraviolet lamp) incapable of being seen by naked eyes exist in the cleaned anti-adhesion plate to form a particle source. According to the invention, with the OLED organic vacuum evaporation equipment anti-adhesion plate cleaning agent and the applications thereof, the vacuum evaporation anti-adhesion plate can be thoroughly cleaned and does not have microscopic organic residues so as to reduce the risk of the occurrence of particle in the equipment operation process, and the anti-adhesion plate material can be prevented from being damaged in the cleaning process so as to prolong the service life of the equipment and reduce the purchasing cost.

Description

technical field [0001] The invention relates to a cleaning agent for an anti-sticking plate of OLED organic evaporation equipment and its application. Background technique [0002] With the continuous development and change of panel display technology, traditional electron tube and liquid crystal transistor display technologies have gradually matured. Based on Organic Light Emitting Diode (OLED), as a new type of pure solid-state display technology, it has the previous technical advantages and is With unique advantages such as self-illumination, ultra-thin, fast response, and wide viewing angle, OLED display technology has been extensively researched and produced. [0003] The preparation of the organic light-emitting layer in the OLED display screen usually adopts vacuum evaporation technology, that is, in the vacuum chamber equipment, the evaporation material in the crucible is heated to evaporate it and deposit it on the target substrate. It involves the use of the anti-...
