Embodiment 1

[0040] Embodiment 1: Preparation of UV curing antistatic agent a

[0041] (1) Synthesis of alkylamide imidazoline: First, add 14.4 g of acrylic acid to a four-necked flask equipped with a water separator, reflux condenser, thermometer and stirrer, and heat up to 130°C; then use a constant pressure dropping funnel to slowly Add 12.4g of diethylenetriamine dropwise, during the dropwise addition process, exothermic heat can be clearly seen, and at the same time, the color of the reactant gradually deepens, and the temperature continues to rise to 160°C after the dropwise addition; then add 8.0g of water-carrying agent xylene, and react for 3 hours, The generated water and xylene are azeotropically separated by a water separator. Finally, continue to raise the temperature to 200°C to carry out the cyclization reaction, and finish the reaction after dehydration to generate an imidazoline intermediate.

Abstract

The invention belongs to the field of fine chemical engineering coatings, and particularly relates to an active antistatic agent and an ultraviolet light polymerization antistatic coating thereof. The active antistatic agent is prepared by adopting the steps of: preparing a tetrahydroglyoxaline intermediate, introducing an active group and carrying out quaternary ammonium salinization on the tetrahydroglyoxaline intermediate. The ultraviolet light polymerization antistatic coating comprises the antistatic agent. The active antistatic agent prepared by adopting the invention has the characteristics of small molecular weight and low viscosity, and can be used as an active diluting agent in oil-based and water-based coating systems. The ultraviolet light polymerization antistatic coating prepared by adding the active antistatic agent provided by the invention is capable of enabling a coating film to obtain durable and excellent antistatic performance under the condition of no need of adding the antistatic agent, resists washing and wiping, is heat-resistant and stable, and is strong in adhesive force; and meanwhile, the coating film also has the characteristics of good transparency, strong decoration property and the like, and can be widely applied to PVC (polyvinyl chloride) plastics and woodware industries.

Description

technical field [0001] The invention belongs to the field of fine chemical coatings, and in particular relates to an active antistatic agent and an ultraviolet light curing antistatic coating. Background technique [0002] Ultraviolet (UV) curing is a new type of "green" coating curing technology, which is composed of photosensitive resin, reactive diluent, initiator and a small amount of other additives. Under the irradiation of ultraviolet light, the initiator in the paint decomposes into free radicals to initiate the polymerization reaction of photosensitive resin and active diluent, and finally forms a coating film. Compared with the traditional coating curing technology, UV curing coating has the advantages of fast curing rate, good coating performance, less environmental pollution, and low energy consumption. It has developed rapidly in recent years and is widely used in plastics, wood, leather, and ceramics. and other fields. However, we found that most of the mater...
