Embodiment A～J

[0031] Embodiment A~J (antistatic agent composition)

[0032] The above-mentioned homopolymer (A) and the hygroscopic inorganic salt (B) were compounded according to the ratio shown in Table 2 to prepare the antistatic agent compositions of Examples A~J of the present invention.

[0033] Table 2

[0034]

Embodiment 1～10 and comparative Embodiment 1～4

[0042] Embodiment 1~10 and comparative example 1~4 (PVC resin composition)

[0043] Using various antistatic agent compositions of Examples A~J of the present invention or Comparative Examples A~D, mixed in PVC resin according to the ratio shown below, using an extruder at 170°C and 55rpm to prepare Granular resin composition. The obtained pellets were formed into disk-shaped (100 mm in diameter x 1.6 mm in thickness) test pieces at a drum temperature of 175° C. using an injection molding machine.

[0044] The formula of polyvinyl chloride resin composition consists of (unit: part):

[0045]

[0046] The surface resistance values ​​of these test pieces were measured by the following method, and the antistatic performance and appearance were evaluated. The evaluation results are shown in Table 4.

[0047] (1) Antistatic performance evaluation method:

[0048]A. Store various test pieces in the environment of temperature 23°C, humidity 15% and temperature 23°C, humidity 53...

Embodiment 11～20 and comparative Embodiment 5～8

[0057] Embodiment 11~20 and comparative example 5~8 (EVA resin composition)

[0058] Use various antistatic agent compositions of Examples A~J of the present invention or Comparative Examples A~D, mix them in EVA resin according to the ratio shown below, and use an extruder to make a granular resin composition. The pellets were formed into disk-shaped (diameter 100 mm×thickness 1.6 mm) test pieces using an injection molding machine.

[0059] The formula of EVA resin composition consists of (unit: part):

[0060]

[0061] The test pieces prepared above were subjected to the same evaluation test as in Examples 1-10, and the evaluation results are shown in Table 5.

[0062] table 5

[0063]

[0064] In Table 5, the blank is an EVA resin test piece to which no antistatic agent composition has been added. The test pieces of Examples 11-20 correspond to adding the antistatic agent compositions of Examples A-J respectively, and the test pieces of Comparative Examples 5-8 cor...

Abstract

The present invention provides an antistatic agent composition, containing general formula (I) The homopolymer (A) of the shown ionic liquid and at least one hygroscopic inorganic salt (B), wherein, X- is an anion, and the molecular weight of the homopolymer (A) is 600-2000. The antistatic agent composition of the present invention has excellent antistatic performance, is durable and effective, and has little dependence on humidity. At the same time, the present invention also provides the antistatic synthetic resin composition added with the antistatic agent composition of the present invention and molded articles made therefrom.

Description

technical field [0001] The invention relates to an antistatic agent composition added to thermoplastic synthetic resins, which does not damage the appearance of products, has excellent antistatic performance, is durable and effective, and has little dependence on humidity, and an antistatic thermoplastic synthetic resin containing the antistatic agent composition. Resin composition and molded article. Background technique [0002] Due to the advantages of light weight, low cost and easy processing, thermoplastic synthetic resin has become an indispensable and important raw material in many fields. An important property of thermoplastic synthetic resins is high electrical insulation, and thus thermoplastic synthetic resins are widely used as various parts of electrical products. However, because the insulation is too high, there will be problems such as friction that cause the product to be electrified. [0003] The charged thermoplastic synthetic resin will attract the sur...
