Abstract

The invention discloses a water-based cleaning agent for liquid crystal cleaning, and belongs to the technical field of microelectronic materials. The water-based cleaning agent is prepared from components in percentage by mass as follows: 1%-15% of a Gemini type organic silicon block polyether surfactant, 1%-30% of C4-C10 alcohol ether, 1%-20% of a cyclic alcohol compound and the balance of water, wherein the sum of the mass percentages of the components is 100%. The Gemini type organosilicon block polyether surfactant has the advantages of super wettability, emulsibility, dispersibility, solubilization, permeability, defoaming property, foam stability, degradability, greenness, environmental protection and excellent liquid crystal cleaning effect, and can be used for effectively cleaningresidual liquid crystals on the surface of a liquid crystal box, in PIN feet and in slits after the liquid crystals are canned under a vacuum condition.

Description

technical field [0001] The invention belongs to the technical field of microelectronic materials, and specifically relates to a water-based cleaning agent for liquid crystal cleaning, which is mainly used for cleaning liquid crystal boxes on the surface of the liquid crystal box, PIN pins and slits after the liquid crystal is filled under vacuum conditions. residual liquid crystals. Background technique [0002] With the improvement of electronic technology, the requirements for cleaning are becoming increasingly strict. As a branch of the electronic industry, LCD cleaning has attracted more and more attention. In the manufacturing process of LCD, there are many cleaning processes, and the effect of cleaning directly affects the various indicators of the finished product. In particular, after the liquid crystal box is filled under vacuum conditions, there will be residual liquid crystal on the surface of the liquid crystal box, PIN feet and slits. If it cannot be effectivel...
