Problems solved by technology

Aqueous solution polymerization has the advantages of low cost, simple operation, and no need to recycle solvents. Reverse-phase suspension polymerization and dispersion polymerization usually require organic solvents and crosslinking agents, and have disadvantages such as long reaction time, low product purity, complicated follow-up treatment, and high cost.

Abstract

The invention discloses a polyquaternium antistatic agent and a preparation method thereof. The preparation method of the polyquaternium antistatic agent comprises the steps of weighing and adding methacryloyloxyethyl trimethyl ammonium chloride (DMC), hydroxyethyl acrylate (HEA), water, sodium hydrogen sulfite (NaHSO3) and ethylene diamine tetraacetic acid tetrasodium (Na4EDTA) into a reactor with a nitrogen atmosphere; weighing a reaction initiator potassium persulfate (KPS) to prepare an initiator solution, warming a reaction solution, uniformly adding the potassium persulfate initiator solution into the reactor while stirring, and performing reacting after the initiator is added; then performing warming at the speed being 1 DEG C / min, and continuously performing reacting; and after finishing reaction, performing cooling at room temperature, so as to obtain a polyquaternium, wherein the conversion rate of monomer is 85 percent or more, and the intrinsic viscosity is 0.45 dL / g to 1.35dL / g. The product obtained in the invention has favorable water solubility and an excellent antistatic property; and the product only needs to be made into a water solution with a concentration of 0.2% so as to achieve an anti-static electricity capacity of a fiber fabric.

Description

technical field [0001] The invention relates to a polyquaternium antistatic agent and a preparation method thereof, in particular to a preparation method of a polyquaternium antistatic agent for fiber fabrics. Background technique [0002] Fabric fibers can be divided into chemical fibers and natural fibers. Synthetic fibers in chemical fibers have electrical insulating properties and have high surface resistance. It is easy to generate static electricity and attract dust during processing and use, and it has a needle-stinging feeling to people. In severe cases, it may cause fire or explosion accidents due to static electricity; natural fibers, such as cotton, due to its own moisture absorption and air permeability, will Some of the static electricity generated can leak out through moisture. However, in northern my country, due to reasons such as dry weather in winter, people wear clothes that are prone to static electricity, which brings certain injuries to the human body...
