電防止性を示す。Conventionally, methods of coating or kneading an antistatic agent have been known in order to reduce electrostatic properties while maintaining transparency, and surfactants or similar substances are usually used as the antistatic agent. It will be done. Since such antistatic agents have a hydrophilic group and a hydrophobic group in the same molecule, they have moderate compatibility with resins, and improve the ionic conductivity of the resin surface by absorbing moisture in the air. increases, indicating antistatic properties.

帯電防止剤が樹脂表面に移行してこなければ大きな帯電
防止効果を発揮せず、樹脂との完全な相溶性はないため
良好な透明性を維持することは困難である等の欠点があ
る。Conventional antistatic agents exhibit their antistatic effect through the mechanism described above, so the presence of water is essential, and they have drawbacks such as their antistatic effect being reduced in low humidity environments. Furthermore, the method of applying an antistatic agent has disadvantages such as the applied antistatic agent is easy to remove and the cost of applying it is high. If it does not migrate to the resin surface, it will not exhibit a large antistatic effect, and since it is not completely compatible with the resin, it has drawbacks such as difficulty in maintaining good transparency.

とするものである。This invention was made in order to eliminate the drawbacks of the above-mentioned conventional products, and by using a composition containing 100 parts by weight of polymethyl methacrylate and 85% by weight or less of 1 cum of perchlorate, the conductivity was improved compared to that of the conventional one. The object of the present invention is to provide a transparent antistatic resin composition that exhibits a good antistatic effect even in a low-humidity environment and has excellent transparency.

酸メチル樹脂の良好な透明性をそこなうことはない。The polymethyl methacrylate resin and lithium perchlorate according to the present invention are in a state in which lithium perchlorate is dissolved as a solid solution in the polymethyl methacrylate resin and dissociated into ions, and when an electric field is applied, the ions moves in polymethyl methacrylate mBW and attempts to neutralize the charge, thereby exhibiting an antistatic effect. Great talent, Aeon's A.
IM occurs within the polymethacrylate methyl resin itself,
Since no moisture is required, there is no reduction in antistatic effect due to drying, and since lithium perchlorate is completely dissolved in polymethyl methacrylate resin, it does not impair the good transparency of polymethyl methacrylate resin. Never.

なる場合がある。The quantitative ratio of polymethyl methacrylate resin and lithium perchlorate has an appropriate range. That is, the blending ratio of lithium perchlorate to 100 parts by weight of polymethyl methacrylate resin must be 85 parts by weight or less. If the amount of lithium perchlorate exceeds 86 parts by weight, crystals of lithium perchlorate may precipitate when blended at normal room temperature, resulting in poor transparency.

It is possible to mold it.
