難点があった。The surface of a synthetic resin has the property of being easily charged, and therefore it is necessary to change these properties by modifying the surface. This antistatic treatment can be roughly divided into coating methods and kneading methods, both of which form a film made of an antistatic agent on the surface of the synthetic resin. However, when an anionic, cationic, or nonionic surfactant, which is conventionally used as an antistatic agent, is applied or kneaded into a synthetic resin, the coating of the active agent forms a film due to the surface tension with the base material. The particles move, causing a so-called island phenomenon, and the coating becomes discontinuous, which tends to weaken the antistatic effect. In addition, these coatings are easily peeled off when they come into contact with other objects and are easily dissolved in water, so that it is currently impossible to provide a durable and water-resistant antistatic effect. Furthermore, surface modification treatments for other synthetic resin properties, such as application of antifogging agents, have also had drawbacks in terms of surface modification effects, durability, and the like.

型品を提供するものである。This invention was made in view of these points, and focused on the water adsorption and retention power of super absorbent polymers, and a resin-mixed super absorbent polymer was kneaded into a synthetic resin base material in advance. A surface modifying agent such as an antistatic agent is applied to the surface of the molded synthetic resin molded product, or it is kneaded with the above-mentioned super absorbent polymer to form a film made of the surface modifying agent to improve the surface modification effect. The objective is to provide synthetic resin molded products that are stable and can be used for a long period of time.
以下この発明の実施例を図について説明する。Embodiments of the present invention will be described below with reference to the drawings.
第１図のものは合成樹脂成型品１の内部に、予め練り込
んだ樹脂練り込み型高吸水性ポリマー２が多数散在して
いる。この合成樹脂成型品１の表面３に帯電防止剤から
成る被膜４を塗布したものである。In the one shown in FIG. 1, a large number of resin-kneaded superabsorbent polymers 2, which have been kneaded in advance, are scattered inside a synthetic resin molded product 1. A coating 4 made of an antistatic agent is applied to the surface 3 of this synthetic resin molded product 1.
これにより被膜４の帯電防止剤は合成樹脂成型品１の表
面３またはその付近に散在する高吸水性ポリマー２に水
分とともに吸着される。As a result, the antistatic agent of the coating 4 is adsorbed together with moisture on the superabsorbent polymer 2 scattered on or near the surface 3 of the synthetic resin molded product 1.
この高吸水性ポリマー２は自重の数１０倍から１０００

。This super absorbent polymer 2 has a weight of 10 to 1000 times its own weight.
It adsorbs twice as much water, is difficult to release and retains water even under some pressure, and is insoluble in water. This is a water-soluble polymer that has been crosslinked and made insolubilized, and this insolubilization treatment can be performed before or after polymerization. Moreover, this super absorbent polymer is easily mixed with other resins and easily dispersed. Furthermore, the resin does not move after solidification and is stable.
従って高吸水性ポリマー２に吸着された帯電防止剤は容
易に離脱せず、保持される。それ故被膜４そのものも合
成樹脂成型品１の表面３に強力に固着し、合成樹脂成型
品１が他物と接触。Therefore, the antistatic agent adsorbed to the superabsorbent polymer 2 is not easily separated and is retained. Therefore, the coating 4 itself strongly adheres to the surface 3 of the synthetic resin molded product 1, and the synthetic resin molded product 1 comes into contact with other objects.
摩擦しても容易に剥がれない。また上記実施例の如く帯

キングを防ぐことができる。It does not come off easily even when rubbed. In addition, when ions such as surfactants as antistatic agents are mixed as in the above example,
Since the superabsorbent polymer has a reduced water adsorption power, water is not adsorbed more than necessary, and the surface 3 of the synthetic resin molded product 1 is less sticky due to water. Therefore, blocking between surfaces can be prevented.

も高吸水性ポリマー２の練込量を加減すれば摩擦抵抗が
調節でき。In this way, the coating 4 made of an antistatic agent is strongly adsorbed and retained by the highly water-absorbing polymers 2 that are kneaded into the resin and scattered in large numbers, so it has excellent abrasion resistance and durability, and is also highly water-absorbent. Frictional resistance can be adjusted by adjusting the amount of polymer 2 mixed in.

摺動するものには最適である。またこの発明を袋に適用

ベリ落ち易し１カへ、これをす入り落ちないように摩擦
抵抗を調節できる。Furthermore, the frictional fluctuation rate R can be made very small, making it ideal for sliding objects such as magnetic tapes. Furthermore, when the present invention is applied to bags, the frictional resistance can be adjusted so that conventional bags easily fall off when filled with appropriate items and stacked, and do not fall into one bag.

is strongly adsorbed, and the antistatic agent 6 gradually bleeds onto the surface 8 of the synthetic resin molded product 5. Moreover, the antistatic agent 6 of the coating 9 is strongly adsorbed by the superabsorbent polymers 7 scattered near the surface 8, and the coating 9 does not peel off easily. Similar to the case shown in Figure 1, this has a stable effect. , and the one in FIG. 3 is a synthetic resin fiber 10 such as polyester or tetron, in which a resin P311 in which a super absorbent polymer and an antistatic agent are kneaded is provided at the center of the synthetic resin fiber 10 such as polyester or tetoron. It always retains the moisture necessary for the inhibitor in the super absorbent polymer, instantly eliminates the static electricity generated on the outer periphery of the synthetic resin fiber 10, and has an antistatic effect. Similarly, antistatic effects can be obtained over a long period of time.
