Description

  The present invention relates to an antistatic thermoplastic resin composition (hereinafter, also simply referred to as “resin composition”) and a molded article formed by molding the same, and in particular, has excellent weather resistance and long-lasting antistatic properties. The present invention relates to an antistatic thermoplastic resin composition capable of providing a molded product and a molded product formed by molding the same.

  Thermoplastic resins are widely used in various molded products such as automotive materials, household appliances, household goods, films, sheets, and structural parts, according to various advantages such as moldability, heat resistance, and low specific gravity. Yes.

  On the other hand, the thermoplastic resin has excellent electrical insulation, but has a problem that it is easily charged by friction or the like. When a molded product made of a thermoplastic resin is charged, static electricity may be generated or the appearance may be impaired by attracting surrounding dust. In addition, when the molded product is an electronic product, the circuit may not operate normally due to charging. In addition, there are problems caused by electric shock. Electric shock not only causes an electric shock to the human body from the thermoplastic resin and gives unpleasant feeling, but also may cause an explosion accident in the presence of flammable gas or dust.

  Nowadays, various methods have been proposed to prevent such an electrostatic failure, and a solution has been made by using an antistatic agent. Examples of such antistatic agents include coating molds that are used by spraying, dipping, coating, etc. on the resin molding surface, and kneading molds that are processed by adding them as additives to polymer materials. In addition to being inferior in antistatic durability, there is a problem that the antistatic agent is wiped off by touching the surface.

  For such problems, Patent Documents 1 and 2 propose an antistatic resin composition containing a polyether ester polymer type antistatic agent. In addition to these, as a molded product to which an antistatic agent is added, for example, artificial turf (Patent Document 3), a molded product for automobile interior parts (Patent Document 4), and the like have been proposed. However, when exposed to strong ultraviolet rays, the resin member discolors or cracks occur on the surface of the resin, which shortens the product life. Therefore, it is required to provide a stable light stabilization effect over a long period of time. ing.

  As a method for imparting a light stabilizing effect to a resin member, it is known to formulate an ultraviolet absorber. For example, in Patent Document 5, a hydroxybenzotriazole-based composition is used for a composition comprising polyphenylene ether and a styrene-based polymer. A resin composition containing an ultraviolet absorber, a hindered amine light stabilizer, and tetrakis- (2,4-di-tert-butylphenyl) -4,4′-biphenylene phosphate has been proposed. Patent Document 6 proposes an agricultural polyethylene terephthalate film to which an ultraviolet absorber such as a benzophenone compound or a benzotriazole compound and an antifogging agent are added. Furthermore, in Patent Document 7, a light diffusing agent, a benzophenone-based, a benzotriazole-based, a malonate ester-based UV absorber, a hindered amine-based light stabilizer, and a long-lasting antistatic agent are added to the styrene-based resin. Light diffusing plates have been proposed, and examples of persistent antistatic agents include polyetheramide compounds and quaternary ammonium salt compounds.

International Publication WO2014 / 115745 International publication WO2014 / 148454 JP 2007-538183 A Japanese Patent Laid-Open No. 10-101865 Japanese Patent Laid-Open No. 7-048506 JP 09-123364 A JP 2006-133567 A

  However, the antistatic agents described in Patent Documents 1, 2 and 5 cannot obtain sufficient antistatic ability unless added in a large amount to the resin. In addition, the ultraviolet absorber can impart a light stabilizing effect to the resin, but there is a problem in maintaining the antistatic performance, or either the antistatic property or the light stabilizing effect is insufficient. There was a need for further improvements. In Patent Documents 1 and 2, an antistatic resin composition containing a polyether ester polymer type antistatic agent is proposed. However, since it does not contain an aromatic dicarboxylic acid, the antistatic resin composition according to the present invention is used. The structure is different from the polymer compound used as the agent.

  Accordingly, an object of the present invention is to provide an antistatic thermoplastic resin composition capable of providing a molded article having weather resistance and durability and excellent antistatic properties, and a molded article formed by molding the same. It is in.

  As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be solved by using a polymer compound having a predetermined structure as an antistatic agent, and the present invention is completed. It came to.
