Description

  The present invention relates to an antistatic composition having excellent antistatic properties, and more particularly to an antistatic composition having a high refractive index. The invention also relates to a method for producing such an antistatic composition. The present invention further relates to molded articles, paints, and coatings that utilize the properties of such antistatic compositions.

  In recent years, it has become important to impart antistatic properties to resins. For this purpose, methods are known in which an antistatic agent such as a surfactant is applied to the surface of a resin molded product, or an antistatic agent is kneaded into the resin. However, in the former method, the antistatic property is remarkably lowered after a long time, so that it is difficult to put it into practical use as a highly antistatic resin having durability. On the other hand, the latter method has a problem that the compatibility between the antistatic agent and the resin is poor, and the antistatic agent is bleeding or blooming on the surface of the molded product, thereby reducing the antistatic effect.

  Antistatic agents such as surfactants are dependent on humidity, and at low humidity, the antistatic effect is deactivated, or after molding the resin, the antistatic effect is at least 1 to There is a problem that it takes 3 days and is slow-acting.

  A method of kneading carbon black or carbon fiber as an antistatic agent into a resin has also been proposed. According to this method, a resin composition having excellent antistatic properties and durability in antistatic properties can be obtained. However, this method has a problem that a transparent molded product cannot be obtained and selection of the color of the molded product is restricted.

Under such circumstances, antistatic resin compositions in which an alkali metal salt such as lithium perchlorate is contained in the resin have been proposed (see, for example, Patent Documents 1 to 3). In addition, the inventors of the present invention describe a metal salt composed of a cation that is an alkali metal or an alkaline earth metal and an anion capable of ion dissociation as a-{O (AO) _n }-group (A is a carbon number). 2 to 4 alkylene groups, n represents an integer of 1 to 7), and a solution in which all molecular ends are dissolved in an organic compound having a CH ₃ group and / or a CH ₂ group is used as a polyamide resin, Antistatic composition of metal salts composed of cation which is alkali metal or alkaline earth metal added to ether ester amide resin, aliphatic polyester, polylactic acid resin, thermoplastic elastomer and rubber, and ion dissociable cation The thing is proposed (for example, refer patent document 4).
