Example Embodiment

[0026] Example 1: Take a copolymer of nylon 6 and polyethylene glycol (its molecular weight is 20000, melting point is 170°C, and polyethylene glycol content is 30% by weight) 80 parts by weight, sulfur-containing surfactant alkylbenzene sulfonate Acid salt, 20 parts by weight of Chemstat 3033 (manufactured by Sanyo Chemicals), 5 parts by weight of IR1010 (hindered phenolic antistatic agent), and antistatic agent A obtained by kneading with a twin-screw extruder at 220°C. Take 5 parts by weight of antistatic agent A and 95 parts by weight of polypropylene for melt blending at 230°C, and injection molding (injection temperature 225°C, injection pressure 8MPa, gold mold temperature 40°C) into a plate-shaped strip, According to ASTM D-257 standard method, the volume resistivity is 1500Ω·cm. The sample was placed in an environment with a temperature of 60° C. and a humidity of 80% for 1 week. It was observed that no substance was deposited on the surface of the sample, and it was e...

[0027] Example 2: Take 65 parts by weight of nylon 6 (its molecular weight is 10000 and its melting point is 222°C), sulfur-containing antistatic agent alkylbenzene sulfonate, 35 parts by weight of Chemstat 3033 (manufactured by Sanyo Chemical Industry), 4,6-tri (3,5-Di-tert-butyl-4-hydroxybenzyl)benzene (IR1330, hindered phenolic antistatic agent) 5 parts by weight, kneaded with a twin-screw extruder at 250°C 剂B。 Agent B. Take 2 parts by weight of the antistatic agent after drying and 98 parts by weight of polyethylene terephthalate (molecular weight: 20000), and mix them into the screw-type single-component spinning machine to prepare the 84T-36f part and distribute it to the undrawn yarn. After 1.6 times of extension, an extended filament is obtained. The stretched yarn is made into a tube-knitted fabric. After the tube-knitted fabric is refined and dried, it is dyed at a high temperature at 120 degrees at a dye concentration of 4% owf. After dyeing, the sample is tested for...

Abstract

The invention discloses an antistatic agent. The antistatic agent mainly comprises, by weight, 15-50% of sulfur-containing surfactant and 85-50% of polyamide polymers. The antistatic agent can be applied to polyester, polyamide and polyolefin. The materials containing the antistatic agent have excellent durable antistatic performance, and excellent performance of original polymers can be maintained.

Description

technical field [0001] The invention relates to an antistatic agent and belongs to the field of polymer chemistry. Background of the invention [0002] Polyester, polyamide, and polyolefin polymers are widely used in various fields such as fibers, resins, and films due to their excellent properties. However, the dielectric constant and conductivity of these conventional polymer materials are very low, and the products made of polymer materials are prone to generate static electricity when they are rubbed, which brings difficulties to the post-processing of the products and contamination, sticky dust, etc. question. Therefore, it is more and more important to endow these polymer materials with antistatic properties. [0003] At present, one of the methods to improve the conductivity of materials is to apply antistatic agents on the surface of molded products, but the disadvantage is that the antistatic agents coated on the surface will slowly fall off with the prolongation ...
