【表】DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a soft transparent antistatic film or sheet. [Prior art] In general, vinyl chloride films or sheets are very easily charged with electricity, and when used in clean room curtains, etc., they become charged and dust tends to adhere to them, and when IC products are packaged, the ICs are destroyed. There were many other problems. To solve the above problem, a conductive paint containing a conductive material mainly composed of carbon black, graphite, etc. on one side of an unplasticized vinyl chloride resin or a plasticized vinyl chloride resin film containing 10% or more of a low-molecular plasticizer. Antistatic vinyl chloride film coated with
47763) has been proposed. However, unplasticized vinyl chloride resin film is hard and cannot be used for clean room curtains, etc. as it cannot be used as a soft film. A sufficient antistatic effect cannot be obtained because it contains a low-molecular plasticizer.In order to obtain a sufficient antistatic effect, a large amount of conductive powder such as carbon black must be added to the conductive paint, and the film There were drawbacks such as the film turned completely black and a transparent film could not be obtained. [Object of the Invention] In view of the above-mentioned drawbacks, the present invention has been made for the purpose of providing a flexible transparent vinyl chloride resin film or sheet that has excellent antistatic effect. [Structure of the Invention] The gist of the present invention is to provide a resin binder on at least one surface of a transparent soft vinyl chloride resin film,
Comprising at least one liquid plasticizer selected from the group consisting of dioctyl phthalate, dibutyl phthalate, and tricresyl phosphate, and conductive powder containing tin oxide as a main component and having a particle size of 0.2 μm or less. , the additive amount of the liquid plasticizer is 10 to 70 parts by weight per 100 parts by weight of the resin binder, and the amount of the conductive powder added is 100 parts by weight in total of the resin binder and the liquid plasticizer. against 70
It consists of a transparent antistatic film or sheet formed by laminating a transparent antistatic coating layer of ~350 parts by weight. The vinyl chloride resin film used in the present invention is transparent and soft, and the vinyl chloride resin is a vinyl chloride homopolymer and a copolymer of a monomer copolymerizable with vinyl chloride monomer. Examples of the copolymerizable monomer include vinyl acetate, ethylene, propylene, (meth)acrylic acid ester, maleic acid ester, vinyl ether, etc., and the copolymerizable monomer in the copolymer accounts for 20% by weight. It is preferable that it is below. The vinyl chloride resin film is made soft by adding plasticizers such as dioctyl phthalate, dibutyl phthalate, and tricresyl phosphate, which are generally used as plasticizers for vinyl chloride resins. The amount added may be appropriately determined depending on the degree of softness of the film, and is generally added in an amount of 10 to 70 parts by weight per 1000 parts by weight of the vinyl chloride resin. The resin binder used in the present invention can be a resin that can bind conductive powder and is generally used as a paint, such as acrylic, vinyl, carbonate, polyester, urethane, epoxy, etc. Among them, vinyl chloride resins and acrylic resins are preferably used from the viewpoint of adhesion to the vinyl chloride resin film. The conductive powder used in the present invention has a particle size of 0.2 μm or less and is mainly composed of tin oxide, and tin oxide containing 0.1 to 20% by weight of antimony is preferably used. The liquid plasticity used in the present invention is at least one selected from the group consisting of dioctyl phthalate, dibutyl phthalate, and tricresyl phosphate, and is a liquid plasticity that is generally used for vinyl chloride resin. It is a plasticizer. The antistatic coating layer in the present invention is a transparent layer consisting of the above-mentioned resin binder, conductive powder, and liquid plasticizer, and when the amount of plasticizer added decreases, the plasticizer in the vinyl chloride resin film migrates.
Over time, the antistatic effect decreases, and the paint becomes harder and less transparent.On the other hand, if the amount increases, it becomes sticky and causes blocking during storage. Ten~
70 parts by weight is added, preferably 20 to 60 parts by weight.
It is preferable that the additive be added in parts by weight, and in an amount approximately equal to the content of the plasticizer in the vinyl chloride resin film. In addition, if the amount of conductive powder added is too small, the surface resistance will increase and the antistatic effect will be lost; if it is too large, the surface smoothness and transparency of the moldable coating layer of the sheet will decrease, and the antistatic effect will not improve. Therefore, 100 to 350 parts by weight are added to a total of 100 parts by weight of the resin binder and liquid plasticizer.
It is preferably added in an amount of 120 to 300 parts by weight. In addition, in order to improve the dispersibility of the conductive powder, the above paint layer contains a silane coupling agent, a titanate coupling agent, a surfactant, a dispersion aid such as oleic acid and lecithin, an ultraviolet absorber, a stabilizer, and a flame retardant. , fillers, etc. may be added. The coating layer is laminated on at least one surface of the soft vinyl chloride resin film, and any method may be used for the lamination, such as methyl ethyl ketone, toluene, ethyl acetate,
A conductive paint is obtained by dissolving and dispersing a resin binder, conductive powder, and liquid plasticizer in an organic solvent such as cyclohexanone, and the resulting paint is sprayed,
Examples include a method in which the resin film is coated on at least one surface of the resin film by a method such as a roll coating method, a bar coating method, or a gravure printing method, and then dried. [Effects of the Invention] The structure of the transparent antistatic film or sheet of the present invention is as described above, and the conductive powder has a particle size of
It is 0.2 μ or less and mainly consists of tin oxide, and both the vinyl chloride resin film and the antistatic coating layer contain a liquid plasticizer, so the plasticizer in the vinyl chloride resin film is the antistatic coating. It hardly migrates to the layer, has an excellent antistatic effect, and does not deteriorate over time. In addition, since the conductive powder is mainly composed of tin oxide with a particle size of 0.2μ or less, the film or sheet is transparent, and by adding a coloring agent, it can be colored red or
It can be beautifully colored in blue and other colors, making it suitable for use as curtains in clean rooms and packaging materials for IC products. [Example] Next, an example of the present invention will be described. Examples 1 to 3, Comparative Examples 1 to 3 A soft vinyl chloride resin film was obtained by a calendaring method from a vinyl chloride compound having the composition shown in Table 1, and one side of the obtained sheet was coated with the composition shown in Table 1. The conductive paint obtained by dissolving and dispersing the mixture in a ball mill for 48 hours was applied with a bar coater and dried to form a transparent antistatic paint layer with a thickness of 1 μm to obtain a transparent antistatic film. The surface resistivity (based on ASTM D-257) and haze value (based on ASTM D-1003) of the obtained film were measured and the results are shown in Table 1. 【table】
