Description
Technical field
The present invention relates to a kind of washing composition, relate in particular in a kind of manufacturing process that is adapted at liquid crystal cell, the washing composition that liquid crystal cell etc. is washed.
Background technology
Liquid crystal cell usually a pair of glass substrate gummed by being formed with electrode and oriented film, inject liquid crystal, seal after scouring, remove liquid crystal, stick deflector plate and make attached to the slit of glass substrate with sealing agent.By this washing procedure to remove liquid crystal be in order to prevent because the residue of liquid crystal plays a part that remover causes that deflector plate comes off in its subsequent handling, the driving mechanism terminal connects not good, driving mechanism bottom filling interface discomfort, in the substrate slimming technology used can disengaging type coating shedding etc. the generation of all faults.
Known liquid crystal molecule as polarized compounds is strong owing to intermolecular interaction, shows strong-hydrophobicity, so generally be difficult to disperse or dissolve to water system.Therefore, in order to wash, to remove, use the washing composition that has added ionic promoting agent, ionic washing assistant, ionic emulsifier etc. to be considered to the method for main flow attached to the liquid crystal on the liquid crystal cell.As such washing composition, the washing composition (patent documentation 1) that contains intercalating agent and alkaline matter, the washing composition (patent documentation 2) that contains the salt of being made up of ammonium cation and phosphoric acid ester negatively charged ion etc. are for example arranged.Again, also can use the intercalating agent be made up of the catechuic acid concentrated solution and combination, the quadrol of tensio-active agent is combination of intercalating agent and tensio-active agent and sulfonate etc.

Yet, in the past for washing, remove the washing composition that uses attached to the liquid crystal on the liquid crystal cell and contain ionic substance, again, hygroscopic matter also is one of its ingredient.Therefore, the problem of existence is, if the part of these washing composition remains in the terminal part of liquid crystal cell, just tends to owing to ion moves electronic migration when causing liquid crystal drive with planar water.
Again, people are considering the nonpolar or polar solvent replacement ionic substance with parts such as halogen series solvent, tetrahydrofuran (THF) or acetone., these solvents are in burning-point, security, environmental problem or take the aspects such as necessity of explosion-proof method to have problems, and use very difficult in reality.
The content of invention
The present invention is in order to solve so far to washing, to remove the liquid crystal cell that uses attached to the liquid crystal on the liquid crystal cell and make with existing above-mentioned technical problem in the washing composition.
That is, the object of the present invention is to provide a kind of detergency height, nonionic that corrodibility is low is detergent composition.
Another object of the present invention is to provide a kind of washing, remove the liquid crystal cell washing composition that ability is strong, cost is low and safe attached to the liquid crystal on the liquid crystal cell again.
For achieving the above object, detergent composition of the present invention is characterised in that, contains: (a) the poly suboxygen alkyl alkyl oxide of the poly suboxygen alkyl styryl phenyl ether of 20 weight %～60 weight %, (b) 40 weight %～80 weight % ((a) and total (b) are 100 weight %).
Detergent composition of the present invention with this formation is because to the solvability height of liquid crystal, be again nonionic, so the problem that electronic migration brought when moving the liquid crystal drive that causes with planar water by ion is eliminated.
Preferably (a) poly suboxygen alkyl styryl phenyl ether accounts for 30 weight %～50 weight % to the weight ratio of 2 kinds of compositions that detergent composition of the present invention is contained, (b) poly suboxygen alkyl alkyl oxide accounts for 50 weight %～70 weight %.
Here, if composition (a) poly suboxygen alkyl styryl phenyl ether is characterised in that it is the polyalkylene oxides affixture of styrenated phenol, then can easily obtain with known synthetic method.Particularly, it is desirable to (a) poly suboxygen alkyl styryl phenyl ether is the addition polymer of the epoxy alkane of styrenated phenol and carbon number 2～4.At this moment, it is desirable to (a) polyoxy alkylidene styryl phenyl ether and be the addition polymer of epoxy alkane of the carbon number 2～4 of 1 mole of styrenated phenol and 4 moles～5 moles.Like this, be about 4 moles～5 moles by the resultant that adds that makes epoxy alkane, the molecular polarity of poly suboxygen alkyl styryl phenyl ether is died down, on the other hand, can improve solvability to liquid crystal.
Again, usually styrenated phenol exists with a single vinylbenzene thing, toluylene thing, triphenylethylene thing, if it is characterized in that, the purity of the single styrenated phenol in the styrenated phenol then can reduce the influence of the electronic migration when coming free ion to move the liquid crystal drive that causes with planar water significantly more than 85%.Especially it is desirable to (a) poly suboxygen alkyl styryl phenyl ether is the addition polymer of 1 mole of single styrenated phenol and 5 mol of alkylene oxide hydrocarbon.
Again, composition (b) poly suboxygen alkyl alkyl oxide is if is characterized in that having the straight or branched alkyl of carbon number 4～carbon number 18, then can improve the solvability of detergent composition of the present invention in water by leaps and bounds, thus can be modulated into can aqueous dispersions the aqueous cleaning that uses of form.
Here, (b) the poly suboxygen alkyl alkyl oxide it is desirable to, and the addition mole number of the alkylene oxide of carbon number 2～carbon number 4 is 1～10, especially it is desirable to, and the addition mole number of carbon number 2 or 3 alkylene oxide is 6.Better is that (b) poly suboxygen alkyl alkyl oxide has isodecyl.
But the present invention also can be understood as be have following feature the liquid crystal cell washing composition: the mixture and (c) water that contain the poly suboxygen alkyl alkyl oxide ((a) and total (b) are 100 weight %) of the poly suboxygen alkyl styryl phenyl ether that comprises (a) 20 weight %～60 weight %, (b) 40 weight %～80 weight %, with respect to mixture 1g with above-mentioned ratio of components, the content of water is 100g～1000g, and it washs, removes the excellent property attached to the liquid crystal on the liquid crystal cell.
It is desirable to (c) water here, is ion exchanged water.
