Coating
Coating 2 in glass interval paper 1 contains cationic polymer (A), i.e. mean molecule quantity is 200~1,000,000 water
The cationic polymer of dissolubility.In addition, mean molecule quantity then means to utilize gel as long as no specified otherwise in this specification
The weight average molecular weight (MW) by polystyrene conversion that permeation chromatography is determined.In addition in this manual, water solubility refers to normal
The property of a corpse or other object for laboratory examination and chemical testing (as solution, occurring without muddiness) more than 1 mass % is dissolved in the pure water of warm (25 DEG C).
Coating 2 in glass interval paper 1 is preferably only made up of cationic polymer (A), but as long as not damaging the present invention
Effect in the range of, as needed can contain cationic polymer (A) beyond composition.
Cationic polymer (A) preferably has multiple cation groups and does not have anion base substantially in intramolecular
Group.As the cation group in cationic polymer (A), specifically, amino, quaternary ammonium group etc. can be enumerated.Cationic polymerization
Thing (A) by with these cation groups so that easily the surface with body paper is electrically coupled.Cationic polymer (A) is real
Without anionic group refer to for example except the contained anionic group residual such as starting compound, polymerization initiator is a little in matter
Degree amount beyond, do not contain anionic group.
The surface of the body paper used in glass interval paper is generally negatively charged.If such body paper surface using sun from
Sub- polymer (A) forms coating, then the cation group that cationic polymer (A) has carries out electric knot on the surface of body paper
Close, thus obtain that there is the glass interval paper of the coating for being firmly fixed at body paper surface.Preferred cationic polymer (A) is had
The number of some cation groups be can turn into cationic polymer (A) cation group and body paper be electrically coupled and contain sun from
The coating of sub- polymer (A) is not easy the number of the structure peeled off from body paper.The cation base that cationic polymer (A) has
The number of group is generally represented by the number of the average cation group in every 1000 molecular weight.
Hereinafter, the number that cationic polymer (A) has average cation group in 1000 per molecule amounts is claimed
It is " cation group density " that unit is represented by [eq/MW1000].Cation group density tool in cationic polymer (A)
3~40 [eq/MW1000] are preferably for body.
If cation group density be 40 [eq/MW1000] below, it assumes that even if cationic polymer (A) is transferred
In the case of glass plate, can be also readily removable by cleaning.If more than 3 [eq/MW1000], then cationic polymerization
Thing (A) is easily electrically coupled with the surface of body paper.In addition, cation group density is more preferably 30 [eq/MW1000] below.Separately
Outward, cation group density is more preferably more than 3.5 [eq/MW1000], more than more preferably 5 [eq/MW1000].
It can be the network polymers (A1) with three-dimensional net structure as cationic polymer (A), or chain
Shaped polymer (A2).Should illustrate, chain polymer (A2) there can be side chain.Cationic polymer (A) it is preferred average
The number of molecular weight and cation group will depend on the molecular structure of cationic polymer (A) in most cases.Hereinafter, according to
The classification of network polymers (A1) and chain polymer (A2), illustrates to cationic polymer (A).
When cationic polymer (A) is network polymers (A1), generally, cation group is present in network polymers (A1)
Surface and inside.Furthermore, it is believed that in the glass interval paper 1 with the coating 2 obtained using network polymers (A1), coating
2 is being knot that the cation group that has of network polymers (A1) surface is participated in being electrically coupled for the interface 3a of body paper 3 with body paper 3
Close.When therefore, using network polymers (A1), cation group density is larger, specifically, preferably 10~30 [eq/
MW1000] network polymers (A1), more preferably 15~30 [eq/MW1000].Should illustrate, cationic polymer (A) is
During network polymers (A1), constitute coating network polymers (A1) can for a kind or two or more.
In addition, the mean molecule quantity of network polymers (A1) is preferably 200~100,000, more preferably 200~10,000, especially
Preferably 200~2000.In network polymers (A1), when cation group density is identical, mean molecule quantity is smaller, every 1 point
The specific surface area of son is bigger, ratio of the cation group number that surface is present relative to the internal cation group number for existing
It is higher, therefore mean molecule quantity is preferably above range.
That is, in network polymers (A1), when cation group density is identical, mean molecule quantity is smaller, the coating for obtaining
More it is securely fixed in body paper surface.Should illustrate, as described above, by making network polymers (A1) be water solubility, even if net
In the case that shaped polymer (A1) is transferred to glass plate, removing network polymers (A1) from glass plate is also easily carried out.As going
The method removed, specifically, can enumerate carries out the method for scrubbing etc. with the akaline liquid of pure water or low concentration.
As network polymers (A1), specifically, can enumerate comprising primary amine, secondary amine, polyethyleneimine of tertiary amine etc..Make
It is polyethyleneimine, it is possible to use commercially available product.As commercially available product, for example, the trade name for being Japanese catalyst company system can be enumerated
EPOMIN SP-003 (mean molecule quantities：About 300, cation group density：23.2[eq/MW1000])、EPOMIN SP-
006 (mean molecule quantity：About 600, cation group density：23.2 [eq/MW1000]) etc..
When coating is made up of network polymers (A1), its thickness is sometimes roughly the same with molecular diameter.Now, it is specific and
Speech, the thickness generally 0.5~2.5nm of the coating being made up of network polymers (A1).
When cationic polymer (A) is chain polymer (A2), cation group has the situation and presence for being present in main chain
In the situation of side chain.Under either case, all it is presumed to the main chain of chain polymer (A2) and exists with a part for cation group
Folded in the mode of coating 2 and the interface 3a of body paper 3 and constitute coating 2.
On cation group exist position, in chain polymer (A2) side chain have a case that cation group with
Main chain has a case that cation group is compared, and the free degree is higher.Because the position for controlling the cation group of side chain is difficult
, there is cation group in main chain it is advantageous to chain polymer (A2).Main chain has the chain polymer of cation group
(A2) can possess the side chain without cation group.Should illustrate, cationic polymer (A) is chain polymer (A2)
When, constitute coating chain polymer (A2) can for a kind or two or more.Furthermore, it is possible to the chain for combining more than a kind gathers
Compound (A2) and more than a kind of network polymers (A1) and constitute coating.
During using chain polymer (A2), its mean molecule quantity is preferably 1000~1,000,000, more preferably 10,000~100,000.
The mean molecule quantity of chain polymer (A2) is bigger, and the number of the cation group that surface is present is more.But, if average mark
Son amount is excessive, then main chain is oversize and molecule is susceptible to bend or is folded, therefore the number of cation group that surface is present
Have a declining tendency.If mean molecule quantity is above range, the number of the cation group of surface presence can be increased, because
And it is preferred that.
In addition, during using chain polymer (A2), cation group density is preferably 3~30 [eq/MW1000], more preferably
It is more than 3.5 [eq/MW1000], more than more preferably 5 [eq/MW1000].If cation group density is 30 [eq/
MW1000] below, it assumes that even if in the case that cationic polymer (A) is transferred to glass plate, also can be easy by cleaning
Ground removal.If more than 3 [eq/MW1000], then cationic polymer (A) is easily electrically coupled with the surface of body paper.
Should illustrate, be water solubility by making chain polymer (A2) in the same manner as above-mentioned network polymers (A1), even if
In the case where chain polymer (A2) is transferred to glass plate, removing chain polymer (A2) from glass plate is also easily carried out.Make
It is the method for removal, specifically, can enumerate carries out the method for scrubbing etc. with the akaline liquid of pure water or low concentration.
As chain polymer (A2), specifically, for the chain polymer (A2) that main chain has cation group, example
Such as, diallyl dimethyl ammoniumchloride, polydiene propyl group amine, dimethyl amine-epichlorhydrin condensates salt, dimethyl can be enumerated
Amine-ammonia-epichlorhydrin condensates salt, dicandiamide-formaldehyde condensation product salt, dicyandiamide-diethylenetriamine condensation product salt etc..
In addition, having the chain polymer (A2) of cation group as side chain, specifically, poly- (acrylic acid can be enumerated
Dimethylaminoethyl methyl chloride quaternary ammonium salt), poly- (dimethylaminoethyl methacrylate methyl chloride quaternary ammonium salt), trimethyl ammonium
Alkyl acrylamide polymer salt, PAH, polyvinyl amidine etc..
As these chain polymers (A2), it is possible to use commercially available product.As commercially available product, for example, as polydiene propyl group
Alkyl dimethyl ammonium chloride (PDAC or PDADMAC；Represent the abbreviation of the compound before bracket.It is same as below), FPA100L can be enumerated
(trade name, Senka company systems, mean molecule quantity：20000, cation group density：6.2 [eq/MW1000]), as dimethyl
Amine-epichlorhydrin condensates salt (DE), can enumerate KHE104L (trade name, Senka company systems, mean molecule quantity：100000, cation
Groups density：7.3 [eq/MW1000]), as dimethyl amine-ammonia-epichlorhydrin condensates salt (DNE), KHE100L (business can be enumerated
The name of an article, Senka company systems, mean molecule quantity：100000, cation group density：8.1 [eq/MW1000]), as poly- (methyl-prop
Olefin(e) acid dimethylaminoethyl methyl chloride quaternary ammonium salt) (PQEM), can enumerate FPV1000L (trade name, Senka company systems, averagely
Molecular weight：It is not clear, cation group density：3.7 [eq/MW1000]) etc..
When coating is made up of chain polymer (A2), the main chain of molecule as described above exists with a part for cation group
Folded in the mode with the interface of body paper and constitute coating, therefore its thickness can be close according to molecular chain length, cation group
Degree equimolecular designs suitably to adjust.
However, when there is coating on the body paper and its at least one interarea of glass interval paper, coating can be being formed
Difference is set according to thickness according to position in face on body paper.For example, coating can turn into concavo-convex surface as a whole.
If enumerating other examples, when being overlooked from the thickness direction of coating, can so that clathrate is integrally formed in the way of thickness is thicker
Part be arranged to wire.If enumerating other examples in addition, can have cated thickness with irregular position relationship thin
Region and thickness region.Should illustrate, coating can stepwise change in the thickness of the boundary member in these regions, also may be used
With slowly varying.
So, difference is set by the thickness according to coating, so that glass interval paper can have easily in coated side
