Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antistatic transparent vinyl chloride resin film or sheet suitable for partitioning a clean room or the like and having excellent antistatic properties and flame retardancy.

[0002]

2. Description of the Related Art Films or sheets based on a soft vinyl chloride resin, which is made by softening a vinyl chloride resin with a relatively large amount of a plasticizer, have various transparency and flexibility. It is used for equipment covers, curtains for partitioning indoors, etc., and in the case of applications requiring flame retardancy, use flame retardant plasticizers,
Ingenuity such as blending flame retardant has been made.

However, such a film or sheet has the drawbacks that it is easily charged with static electricity and easily adheres with dust, so that there is a problem in using it as a partition curtain of a clean room as it is. As a method of reducing the electrostatic property, for example, a surfactant is kneaded into the base resin, but the level of the antistatic effect is low and the sustainability is insufficient. There is a problem in that the agent bleeds out on the surface of a film or the like and reduces transparency. Further, as another method, a film in which a coating layer in which carbon black or a conductive filler is dispersed in a binder resin is applied uniformly or in a mesh pattern on the surface of the film or sheet to form a coating layer is proposed. However, this type is inferior in transparency and smoothness, and the adhesiveness with the soft vinyl chloride resin layer as the base material is not sufficient,
There is a problem that the layer peels off during use and the durability decreases.

[0004]

(In the formula, R ⁶ is a hydrogen atom or a methyl group, and X is an ionic residue containing a quaternary ammonium salt or a metal salt.) The present invention will be described in detail below.

In the present invention, the vinyl chloride-based resin used for the vinyl chloride-based resin film or sheet as the base material is, in addition to polyvinyl chloride, a copolymer with other comonomer mainly containing vinyl chloride, or a mixture thereof. Alternatively, a mixture of these and another polymer or copolymer can be used. The phosphoric acid ester-based plasticizer to be blended with the vinyl chloride-based resin in the present invention should be one that acts as a flame retardant itself and contributes sufficiently to softening the film, and does not impair the transparency of the film or sheet. However, it is not particularly limited. Specifically, for example, tricresyl phosphate, trixyl phosphate, diphenyl cresyl phosphate, diphenyl isopropyl phenyl phosphate, triaryl phosphate plasticizers such as phenyl isopropyl phenyl phosphate, or trimethyl phosphate, triethyl phosphate, Examples include trialkyl phosphate plasticizers such as tributyl phosphate, tri-2-ethylhexyl phosphate, and tributoxyethyl phosphate. From the viewpoint of imparting flame retardancy, it is preferable to use a triaryl phosphate plasticizer. The addition amount of these phosphoric acid ester-based plasticizers needs to be in the range of 5 to 80 parts by weight, preferably 10 to 70 parts by weight, per 100 parts by weight of the vinyl chloride resin. If the amount of the phosphate ester plasticizer is less than 5 parts by weight, the effect of imparting flame retardancy is not sufficient, and if it is more than 80 parts by weight, the film or sheet becomes too soft and sticky, which is not preferable.

In the present invention, a commonly used plasticizer such as a phthalate ester plasticizer may be used together with the phosphate ester plasticizer. In addition to these, various resin additives that are usually blended, such as heat stabilizers, lubricants, UV absorbers, pigments,
A dye or the like may be blended, and these additives can be used in an amount of 10 parts by weight or less based on 100 parts by weight of the vinyl chloride resin.

To mix the plasticizer and various resin additives with the vinyl chloride resin, a ribbon blender, a Banbury mixer, a super mixer, or any other known mixer can be used. To form the resin mixture into a film, known techniques such as an extrusion molding method such as a T-die method and an inflation method, a calender molding method, a casting method, and the like can be used. The thickness of the obtained film or sheet is preferably 0.05 to 5 mm.

Next, a coating film formed on at least one side of the film is a composition of a polymeric antistatic agent and a binder resin. The polymeric antistatic agent of the present invention is a copolymer having a repeating unit represented by the following general formula [I] having a polyester structure as a side chain and an ionic repeating unit whose main chain is represented by the following general formula [II]. It is united.

Although the reaction proceeds even without a catalyst, a tin catalyst such as dibutyltin dilaurate, dibutyltin dioctoate, or dibutyltin mercaptide may be used to accelerate the reaction rate.

The reaction of the polyester alcohol with the above-mentioned [VI] is a condensation reaction or a transesterification reaction, and these may be reacted in an equimolar manner. When a condensation reaction is adopted, a hydrogen halide is produced as a by-product, so a deoxidizing agent such as a tertiary amine may be used, or the reaction may be carried out under an inert gas stream. When the transesterification reaction is adopted, known transesterification catalysts such as mineral acids such as hydrochloric acid and sulfuric acid, metal salts such as zinc, calcium and magnesium, metal alkoxides such as titanium tetrabutoxide may be used.

Particularly preferred as the monomer having these ionic residues are dimethylaminoethyl (meth) acrylate, diethylaminoethyl (meth) acrylate and dipropylaminoethyl (meth) acrylate.
A primary ammonium salt and a metal salt of (meth) acrylic acid. The copolymerization of the polyester macromonomer [III] and the vinyl monomer [IV] can be easily carried out by a usual radical polymerization method. That is, a polyester macromonomer [III] and a vinyl-based monomer [IV], an azo compound or, usually, a radical polymerization initiator such as a peroxide,
0.1 to 10% by weight is added, and the temperature is from 0 ° C to 200 ° C.
It can be suitably carried out in a time of 24 hours. Here, a chain transfer agent such as alkyl mercaptan may be added to adjust the degree of polymerization. As the polymerization method, any of bulk polymerization, solution polymerization, emulsion polymerization, suspension polymerization and the like, which are usually employed in radical polymerization, may be used.

The weight ratio of the polyester macromonomer [III] to the vinyl monomer [IV] is 10: 90-9.
It is in the range of 0:10, preferably 20:80 to 80:20. When the ratio of the vinyl-based monomer [IV] is less than 10, the antistatic property is difficult to develop, and when the ratio of the polyester macromonomer [III] is less than 10, the affinity with the binder resin is poor. Is not preferable.

This antistatic agent copolymer was added to a mixed solvent of methyl ethyl ketone / methanol (7/3) at a concentration of 0.5.
Intrinsic viscosity η dissolved at 25 ° C and dissolved at g / dl
inh is 0.02 or more. When ηinh is less than 0.02, the molecular weight is too small, so that bleeding out easily occurs on the surface of the soft vinyl chloride resin film or sheet that is the base material, and the antistatic performance is poor, which is not preferable.

In the present invention, a polymeric antistatic agent is used together with a binder resin. Any binder resin may be used as long as it has good adhesiveness to the soft vinyl chloride resin film or sheet as the base material, good transparency, and further has good affinity with the surfactant, but particularly vinyl chloride resin. It is preferable to use a resin, an acrylic resin, a polyester resin, a urethane resin or an ultraviolet curable resin, or a mixture of two or more kinds of these resins. As the vinyl chloride resin as the binder resin, a vinyl chloride homopolymer or a copolymer of a vinyl chloride monomer and a copolymerizable monomer can be used. In this case, examples of the copolymerizable monomer include vinyl acetate, ethylene, propylene, (meth) acrylic acid ester, maleic acid ester, vinyl ether and the like. As the acrylic resin, a homopolymer of acrylic acid or an alkyl ester of methacrylic acid or a mixture thereof with a monomer of an alkenylbenzene, and a copolymerizable α-β ethylenically unsaturated monomer An acrylic resin obtained by copolymerizing a polyester resin is a polyester resin obtained by a dehydration condensation reaction of a glycol and a dibasic acid, and a urethane resin is a polyester having a hydroxyl group at the terminal. , Or a polyurethane-based resin obtained by reacting a polyalkylene glycol with an excess of an aliphatic or aromatic polyisocyanate, as the ultraviolet curable resin, butyl acrylate, tetrahydrofurfuriacrylate, a monofunctional monomer such as vinylpyrrolidone And polyurethane acrylate, polyester acrylate Examples thereof include a mixture of a polyfunctional oligomer such as a salt and the like, and an additive such as a polymerization initiator and a leveling agent added thereto.

The mixing ratio of the polymer antistatic agent (a) and the binder resin (b) is a: b = 1: 99 to 9 by weight.
It must be 9: 1, and preferably 10:90 to 90:10. If the ratio of the polymeric antistatic agent is less than 1, antistatic properties cannot be obtained, and if it is more than 99, the film forming ability is poor and cracking wrinkles occur, which is not preferable.

To form a coating film of a composition of a polymeric antistatic agent and a binder resin on a vinyl chloride resin film or sheet, the binder resin is dispersed in a solution prepared by dissolving the polymeric antistatic agent in an organic solvent. The above-mentioned antistatic paint may be applied by a known method such as a spray method, a bar coating method, or a roll coating method. The thickness of the formed film after drying is preferably 0.1 to 20 μ, and more preferably 1 to 10 μ. When the thickness of the coating is less than 0.1 μ, the antistatic property is inferior, which is not preferable, and when it is thicker than 20 μ, the performance obtained is high in cost.

[0063]

EFFECT OF THE INVENTION The antistatic transparent film or sheet of the present invention has excellent transparency and antistatic properties, and does not cause peeling of the coating even when used for a long time and has excellent durability. And is extremely useful.
