系樹脂成形体の帯電防止方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an antistatic method for a vinyl chloride resin molded article, and more particularly to an antistatic method for a vinyl chloride resin molded article which is inexpensive and can maintain its antistatic effect. Regarding the method.

る。(Prior Art) Vinyl chloride resins are widely used as various molded products, sheets and films because they are inexpensive, have good moldability, and have excellent properties. However, the vinyl chloride resin molded body is easily charged with electricity, which causes various obstacles. In order to prevent such electrification, it has been attempted to impart conductivity to the molded body.

させる方法は，帯電防止効果に優れているものの，高価
であり，生産性も低い。Various methods have been proposed for imparting conductivity to vinyl chloride resin moldings. For example, there is a method of applying a surfactant to the surface of the molded body. There is also a method in which a surfactant, carbon black, metal powder, conductive fibers, etc. are added to a vinyl chloride resin, and the mixture is kneaded and then molded. However, since the surfactant easily bleeds and falls off the surface of the molded body, the antistatic effect is not maintained. Although the antistatic effect is maintained by adding carbon black, metal powder, conductive fibers, etc., it is necessary to add a large amount of these conductive substances in order to obtain the desired conductivity. Therefore, it becomes expensive. The method of depositing a noble metal or metal oxide on the surface of a vinyl chloride resin molding by vapor deposition, sputtering, etc., is excellent in antistatic effect, but expensive and low in productivity.

There is a method of imparting conductivity by using a conductive paint in which a conductive substance such as metal powder is dispersed in a resin solution and applying this to a vinyl chloride resin molded body. Although this method is inexpensive and has an excellent antistatic effect,
Since the conductive material is foreign to the resin, there is still a risk of bleeding or falling off.

る。The vinyl chloride copolymer contains 50 to 96 vinyl chloride units.
It is contained in an amount of, preferably 75 to 94% by weight.
If the amount is less than 50% by weight, the copolymer tends to fall off from the vinyl chloride resin molded product, and a durable antistatic effect cannot be obtained. If it exceeds 96% by weight, the desired antistatic property cannot be obtained. The substituted ammonio group-containing (meth) acrylic acid ester derivative unit represented by the formula (I) is contained in the copolymer in an amount of 1 to 10% by weight, preferably 2 to 6% by weight. If it is less than 1% by weight, the desired antistatic property cannot be obtained. When it exceeds 10% by weight, the antistatic property is improved, but the hydrophilicity is increased, and the solubility in the organic solvent is decreased. For example, it is soluble only in a highly polar organic solvent such as N, N-dimethylformamide. Since N, N-dimethylformamide has a strong dissolving power, it has an unfavorable influence on the physical properties such as dissolution or deformation of the vinyl chloride resin molding. The (meth) acrylic acid polyalkylene oxide ester unit represented by the formula (II) is contained in the copolymer in an amount of 3 to 40% by weight, preferably 5 to 20% by weight. When it is less than 3% by weight, the hydrophilicity is increased and the solubility in the organic solvent is lowered. Even if it exceeds 40% by weight, the antistatic property and the solubility are hardly improved. The compound represented by the formula (II) is expensive and is wasted when it is contained in a large amount in the copolymer.

化ビニル系樹脂成形体が密着性や耐水性に欠ける。As is clear from the examples and comparative examples, the antistatic method of the present invention can provide vinyl chloride resin moldings having a low surface resistivity and excellent conductivity. Therefore, the antistatic effect is high. The obtained molded body has excellent film adhesion and water resistance. Even if antistatic is performed using a copolymer having a substituted ammonio group-containing (meth) acrylic acid ester derivative unit represented by the formula (I), the obtained vinyl chloride resin molded article is , The surface resistivity is high, and the desired antistatic property cannot be obtained. Since the copolymer containing 12% by weight of the monomer unit represented by the formula (I) and the copolymer containing only 2% by weight of the monomer unit represented by the formula (II) are insoluble in the methyl ethyl ketone / toluene mixed solvent, Not used in the method of the invention. In the conventional antistatic method using a surfactant, the obtained vinyl chloride resin molded product lacks adhesion and water resistance.
