Problems solved by technology

However, due to the long rigid structure and strong interaction between molecular chains, conductive polymers prepared by conventional methods are difficult to dissolve.
Directly using conductive polymer powder as a conductive filler and mixing it with UV-curable materials is also prone to uneven particle dispersion, easy agglomeration between particles and increased viscosity of the system
In addition, water-based antistatic UV-curable coatings combine water-based and antistatic properties with UV-curable materials to endow materials with unique properties such as environmental protection, antistatic and high-efficiency photocuring. There are few studies on this aspect.

Abstract

The invention is applicable to the technical field of photocureable coatings, and provides a water-based antistatic photocureable coating and a preparation method thereof. The preparation method comprises the steps that a polypyrrole nanoparticle aqueous solution serves as a conductive component and is mixed with water-based ultraviolet curing resin, a water-based defoamer, a water-based levelingagent, a photoinitiator and other components, and the preparation of the water-based antistatic photocureable coating can be completed. The method is simple, convenient and easy to implement, and theprepared antistatic photocureable coating does not contain volatile organic solvents, does not need to be heated, and is efficient and environmentally friendly, meanwhile, the conductive component polypyrrole nano-particles have good dispersity and stability in a photocuring system, ideal antistatic performance can be obtained with a small addition amount, and the situation that inorganic conductive particles or conductive polymer powder and the like are dispersed unevenly in the photocuring system after being added as conductive filler is also avoided, agglomeration and precipitation are easily caused, and the viscosity of the system is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of photocurable coatings, in particular to a water-based antistatic photocurable coating and a preparation method thereof. Background technique [0002] UV-curable coatings have been widely used for many years due to their advantages such as fast curing speed, low energy consumption, high production efficiency, and good coating performance. The monomer has a certain volatility, which is not conducive to environmental protection and human health. If only non-volatile oligomers are used to prepare high-solid-content light-curing coatings, there will be a problem that the viscosity of the system is too high to affect the construction. Generally, the way to reduce the viscosity of the system is to add a certain amount of organic solvents, which will also cause solvent volatilization. pollution problems. If water is used instead of active diluent in UV-curable coatings, the above problems can be avoided. On the...
