Abstract

The invention relates to a durable antistatic agent for acrylic fibers and a preparation method thereof. The antistatic agent is prepared through the following steps: in the first step, in the presence of an initiator, alkylphenol polyoxyethylene ether acrylate or alkylphenol polyoxyethylene Oxyethylene ether methacrylate is polymerized with vinyl monomers with epoxy functional groups to generate antistatic macromolecules. In the second step, the above-mentioned antistatic agent macromolecule is prepared into a solution, and a curing agent is added to obtain a durable antistatic agent for acrylic fibers. The present invention creatively introduces alkylphenol polyoxyethylene ether side groups and epoxy groups into the synthetic polymer chain, and utilizes the surface activity of the alkylphenol polyoxyethylene ether group (with good water absorption and antistatic properties) ) and the cross-linking activity of epoxy groups to synthesize a cross-linkable curable polymer antistatic agent for surface treatment. The process preferably adopts the solution polymerization method, and the alkylphenol polyoxyethylene ether (meth)acrylate is copolymerized with the vinyl monomer with epoxy group, the conversion rate of the monomer is high, and the reaction is stable. The polymerization reaction solution and the curing agent are prepared in a certain proportion to form a solution with a certain concentration, coated on the surface of the fiber, and then dried and cured to obtain the antistatic fiber. The operation is simple, and the antistatic performance of the obtained fiber is excellent (volume specific resistance is less than 10 8 Ω·cm), and has good durability.

Description

technical field [0001] The invention relates to a durable antistatic agent for acrylic fibers and a preparation method thereof, in particular to a durable antistatic agent for acrylic fibers containing alkylphenol polyoxyethylene ether side groups and epoxy groups and a preparation method thereof. Background technique [0002] As we all know, acrylic fiber is one of the main varieties of synthetic fibers. It has bulky texture, soft feel, low density, low thermal conductivity (40% lower than polyester), and good thermal performance. It is called artificial wool and is the best substitute for wool. Articles, and cheap, good air permeability, low shrinkage (only 0.4%), as raw materials for clothing, its proportion in the field of cotton spinning accounts for 30 to 50%. [0003] When conventional acrylic fiber does not add finishing agent, the volume resistivity is 10 under standard conditions. 13 -10 14 Ω.cm, which is an insulating material, can generate static electricity du...
