Problems solved by technology

However, the antistatic performance is generally poor, and it cannot solve the static electricity problem in the subsequent weaving process.
For example, U.S. Patent US20120004352, although the antistatic performance in the oil formulation can meet the requirements, but due to the existence of higher fatty acid metal salts and antistatic agents, this type of oil requires relatively harsh dispersion conditions, and as time goes on, the oil The agent is easily turbid and precipitated, and in practical applications, there are also problems such as solid stearate blocking the pipeline of the oil agent and the pinholes of the circular weaving machine.
Although patent CN104372446A uses quaternary ammonium salt cationic surfactant as antistatic agent to add to the oil agent, according to the molecular structure characteristics of the antistatic agent, it does not consider its compatibility with the oil agent grouping, and still cannot fully meet the production requirements

Abstract

The invention relates to an antistatic agent for a spandex oiling agent and a preparation method of the antistatic agent. The antistatic agent for the spandex oiling agent is prepared by the followingsteps: reacting a hydrogen-containing siloxane polymer with an epoxy compound with double bonds to prepare an epoxy siloxane polymer, then distilling to remove unreacted residual raw materials, so asto obtain the epoxy siloxane polymer for the next reaction, reacting organic carboxylic acid with organic tertiary amine to obtain an organic acid quaternary ammonium salt, and finally, reacting theepoxy siloxane polymer with the organic acid quaternary ammonium salt to obtain the antistatic agent for the spandex oiling agent. The antistatic agent for the spandex oiling agent not only has good antistatic performance, but also can be stably dispersed in basic components of the spandex oiling agent, does not coagulate after being placed for a long time, and can be widely applied to the technical field of spandex oiling agent auxiliaries.

Description

technical field [0001] The invention relates to the technical field of spandex oil additives, in particular to an antistatic agent for spandex oil and a preparation method thereof. Background technique [0002] Polyurethane elastic fiber is a high-performance fiber with high elongation and high elastic recovery rate. It not only has the elasticity of rubber silk, but also has some properties better than rubber silk, such as fineness, high strength, and large elastic modulus. , small specific gravity, soft hand feeling and high elasticity. When polyurethane elastic fiber is used to spin spandex yarn, a good spandex spinning oil can not only endow spandex with good formability and bundleability during spinning, but also endow spandex yarn with good smoothness and antistatic properties. Spandex filaments are easy to unwind in subsequent applications, without continuous filaments and without sagging. [0003] There are many types of spandex spinning oils, and antistatic agents...
