Abstract
The invention discloses a LCD water-based abluent of amine alkali and non-ion surface activator, which comprises the following parts: 20-70 percent amine alkali, 5-40 percent JFC, 5-20 percent non-ion surface activator and deionized water. The invention is beneficial to remove the surface residues, which improves the surface finishment of product.
Description
Technical field
The present invention relates to a kind of clean-out system, in particular, relate to a kind of aqueous cleaning agent that is applicable to the scavenging solution crystal display screen.
Background technology
Liquid crystal is the material that a class has property, it under liquid state, keep within the specific limits crystal distinctive three-dimensional space can ordered arrangement feature.The liquid crystal material that uses on the liquid crystal display is the organic compound with class formations such as cholesterol ester, cyanobiphenyl, Santosol 360s.Liquid crystal material is encapsulated into after two conductive glass centres, unnecessary liquid crystal material is arranged in that its periphery is always residual, as not removing the performance that will influence liquid-crystal display, when serious even the corrosion target lead-in wire, cause complete machine to scrap.Along with the develop rapidly of microelectronics, the surface clearness of liquid crystal display (LCD) and other substrate glass and various device substrate is had higher requirement.
The clean-out system that is applicable to LCD has three types of aqueous cleaning agents, half aqueous cleaning agent, solvent cleaner, and water base and half water base cleaning is applicable to ultrasonic washing process route, and solvent cleaner is applicable to gas phase ultrasonic cleaning operational path.At present, the main ingredient in the half water base and leaning solvent is solvency action based on alkane to liquid crystal, cleaning machine manufacture-illegal Chang Danyi, and cleaning efficiency is low.Simultaneously, the alkanes component all is low-flash, and is inflammable, and therefore explosive material causes a kind of potential to threaten to the production of factory and workman's safety.And because the alkanes component can not recycle, therefore the discharging back pollutes environment.Aqueous cleaning agent is then because advantages such as its low toxicity, environmental protection become the development trend that LCD cleans.But the aqueous cleaning agent that both at home and abroad can adopt now is imperfections all also.The residual liquid crystal of water base cleaning removal LCD is the emulsifying effect based on tensio-active agent and liquid crystal, and emulsification is bigger to ultransonic dependency, and the surface tension of water is bigger than solvent, and is relatively poor to the wettability of slit, influences the cleaning of residual LCD in the slit.Use at present the colored king who is preferably Japan, still limited it and promote the use of owing to it costs an arm and a leg.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, provide a kind of mixing solutions of amine alkali and nonionogenic tenside that uses to eliminate residue, improve product surface smooth finish, good to the wettability of slit, security simultaneously is good, the aqueous cleaning agent for liquid crystal display that price is low.
The present invention is achieved through the following technical solutions:
A kind of aqueous cleaning agent for liquid crystal display is characterized in that being made up of following component by weight percentage: amine alkali 20～70%, JFC 5～40%, nonionogenic tenside 5～20%, balance of deionized water.
Described amine alkali is any in trolamine, diethanolamine, the hydroxyethylethylene diamine.
Described nonionogenic tenside is FA/O series or peregal series or op series non-ionic surfactants.
The present invention has following technique effect:
1. aqueous cleaning agent of the present invention is made up of amine alkali, JFC and nonionogenic tenside, use amine alkali has substituted the mineral alkali in the existing water machine clean-out system, utilize similar principle and organic bases the Decomposition that mixes of high infiltration structure to fat etc., realized that reduction surface tension and strong seepage force enter in the seam, utilize dissolving, decompose the effect of grade and remove organism.Amine alkali has certain solvency action to organism, and chemical reaction can take place amine alkali and organism, helps eliminating the residue of product surface, has improved the smooth finish of product surface.
2. owing to used water and various low toxicity reagent, as amine alkali, JFC, nonionogenic tenside, good environmental protection has been protected workers'health, and not flammable, do not explode simultaneously, security is good.And cost is low, has reduced cleaning charge usefulness, and dilution is used, and cleaning charge is lower.
3. multiple degree of freedom.Clean-out system technological design of the present invention, prescription and concentration have very big degree of freedom, can specialized designs or preparation satisfying specific cleaning needs, thereby can obtain excellent cleaning effect such as particulate, organic film, oil and fat.
4. the mechanism of cleaning more.Nonionogenic tenside can lower surface tension, have effects such as wetting, infiltration, dispersion, emulsification, foaming, washing, make the cleaning function of aqueous cleaning agent that number of mechanisms be arranged, except that dissolving, also comprise saponification, soak into, emulsification, dispersion, interfacial activity power etc.Thereby, reduced ultransonic dependency owing to adopted many cleaning mechanism to overcome serious dependence emulsive problem.
5. adopt JFC (fatty alcohol-polyoxyethylene ether) can be penetrated into the liquid crystal crack as permeate agent, good to the wettability of slit, help removing liquid crystal residual in the slit.
Embodiment
