Problems solved by technology

The technical problem that needs to be solved at present is that the use of general antistatic agents is relatively large, which brings about the decline of the properties of polymer materials, and the problem of precipitation of antistatic agents during use greatly affects the performance of polymer materials.
[0005] However, the current technology has shortcomings in solving the relationship between antistatic properties and polymer physical properties, which is specifically manifested in the adverse changes in the use characteristics of polymers after endowing antistatic properties.
For example, after antistatic polyester is made into fibers, there are problems such as low fiber strength and loss of antistatic properties after fiber dyeing.

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 ...
