Problems solved by technology

However, due to the large amount of lithium bis(trifluoromethanesulfonyl)imide blended with respect to the vinyl chloride resin, the heat resistance is poor, and it turns dark brown when heated at 120°C for 30 minutes, and there is a problem that it loses transparency or conductivity.

Embodiment approach 1

[0065] Various raw material components other than at least one compound selected from lithium bis(trifluoromethanesulfonyl)imide and lithium tris(trifluoromethanesulfonyl)methyllithium used in the group of the present invention can be used as Conventionally known methods and materials for obtaining polyurethane.

[0066] Polyurethanes are usually produced by reacting diisocyanates with polyols. The polyhydric alcohol used in the present invention may be a polyhydric alcohol having at least two active hydrogens in the molecule. Specifically, polyether polyols such as polypentyl glycol, glycerin, trimethylolpropane, sorbitol and other ethylene oxide adducts and propylene oxide adducts, adipic acid, succinic acid, horseradish, etc. Polyester polyols and polybutadiene polyols prepared by reacting acids such as toric acid and fumaric acid with diols such as ethylene glycol and butanediol. Moreover, 1, 4- butanediol, ethylene glycol, propylene glycol, butanediol diethylene glycol ...

Embodiment 1

[0076] Hereinafter, the content of the present invention will be specifically described based on examples, but the present invention is not limited by the examples.

[0077] In addition, "part" in each Example means "part by weight". In addition, "lithium imide" means "lithium bis(trifluoromethanesulfonyl)imide", and "methyllithium" means "lithium tris(trifluoromethanesulfonyl)methyl".

Embodiment 1-1

[0079] To 100 parts of polyethylene adipate (hydroxyl value (OHV); 56), were added 8 parts of ethylene glycol containing 5% by weight of imide lithium (manufactured by Sumitomo Crystal Co., Ltd.), 0.5 parts of water, 0.4 parts of triethylenediamine and 1.0 parts of a silicone-based surfactant (manufactured by Toray Silicone Co., Ltd., trade name: SH-193) were mixed to prepare a prepared solution. 100 parts of a mixture of diphenylmethane diisocyanate and polyethylene adipate matrix terminal isocyanate prepolymer (mixing ratio 9:1) was mixed into the prepared solution, and stirred to react to prepare a polyurethane solution. This solution was left still to obtain a plate-like test piece A1 with a thickness of about 4.5 m.

Abstract

An anti-static composition comprising a resin and a specific alkali metal salt or alkaline earth metal salt; and a method for producing the composition. The anti-static composition is excellent in heat stability, is free from the problem of bleeding out, exhibits its effect independently of humidity, has fast-acting nature, and also exhibits excellent and durable anti-static property.

Description

technical field [0001] The present invention relates to an antistatic composition having good antistatic properties and a method for producing the same. Background technique [0002] In recent years, there has been concern about electromagnetic wave noise caused by electrostatic charge on the surface of molded objects such as plastics or glass, which causes dust to be adsorbed on the surface, and electromagnetic wave noise caused by damage or failure of integrated circuits (ICs) or large-scale integrated circuits (LSIs) due to high voltage of static electricity. Static electricity problems such as causing electronic equipment to malfunction are noticeable. Therefore, the technique of imparting antistatic property to resin is very important. [0003] As a method of imparting antistatic to a resin, a method of coating an antistatic agent such as a surfactant on the surface of a resin, or a method of mixing an antistatic agent into a resin is known. However, in the method of ...
