Abstract

The invention relates to the field of textile auxiliaries, in particular to a preparation method of an environmentally friendly and durable fabric antistatic agent; the invention is used to introduce highly hygroscopic imidazole at the molecular end of acrylic acid polyoxyethylene ether and then graft it on hydrogen-containing siloxane , the hydrophilic polyether silicone oil was prepared, and at the same time, it was cross-linked with the polyolefin wax grafted with polar group sodium acrylate under the action of coupling agent, possessing polar group and hydrophilic group The macromolecular persistent antistatic agent of group, under the action of baking and ultraviolet light, chemical bond is formed on the fabric surface, forms firm combination, forms long-acting antistatic effect; The long-acting and lasting antistatic agent of the present invention has many Excellent performance, such as good antistatic performance, long-lasting antistatic effect, washable, good toughness, not affected by environmental humidity, and little impact on the properties of the base material, is a kind of polymer environmental protection with great commercial prospects. Long-lasting antistatic agent.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of an environmentally friendly and durable fabric antistatic agent. Background technique [0002] Many textiles now contain a large amount of synthetic fibers. Synthetic fibers have many properties superior to natural fibers, so they have been developed rapidly and widely used in recent years. For example, polyester fiber was invented in 1941. It is a synthetic fiber spun from a fiber-forming polymer in which each chain link in a macromolecular chain is linked by an ester group. However, many synthetic fibers are hydrophobic fibers with poor electrical conductivity and are poor conductors. Although synthetic fibers have amorphous parts like cotton fibers, they lack hygroscopic centers. Even at 100% relative humidity, the hygroscopic rate is only 0.6%-0.8%. Therefore, it is easy to generate static electricity and absorb dust, and it is easier to accumulate...
