Abstract

The invention discloses an antibacterial and antistatic ultraviolet-curable coating and a preparation method thereof. The method comprises the following steps: (1) weighing the following raw material in parts by weight: 87-107 parts of substrate resin and 56-68 parts of an active diluting monomer, mixing and ultrasonically dispersing; (2) adding 6-10 parts of a photoinitiator, 14-24 parts of an antistatic agent, 23-35 parts of a fire retardant and 17-23 parts of an antibacterial agent, stirring and heating to 110 DEG C, and reacting for 2-4 hours; and (3) cooling to 75 DEG C, adding 15-18 parts of a flatting agent, 16-20 parts of an antifoaming agent, 10-16 parts of a thickening agent and 6-12 parts of a light stabilizer, and reacting for 1-3 hours, so as to obtain the antibacterial and antistatic ultraviolet-curable coating. The coating disclosed by the invention is short in cuing time, high in hardness, and relatively high in surface resistance, shows a good antistatic function, and also has excellent antibacterial property and flame retardant property; a barrier protection effect can be effectively provided for the coated combustible material; and the preparation method disclosed by the invention is simple, mild in condition and easy to control.

Description

technical field [0001] The invention relates to an antibacterial and antistatic ultraviolet light curing coating and a preparation method thereof, belonging to the field of light curing coatings. Background technique [0002] UV-curable coatings are environmentally friendly and energy-saving coatings that have been successfully developed in recent decades. It has many advantages that traditional coatings cannot match: energy saving, high energy utilization rate; no solvent emissions, safe and pollution-free; fast curing speed, high production efficiency; heat-sensitive substrates can be coated; Layer performance is excellent. Entering the 21st century, people's awareness of environmental protection is constantly increasing, and more and more people choose environmentally friendly products. In the future, this green environmental protection product will surely get greater development. Over the past few years, UV-curable coatings have grown rapidly in fiber optic coatings, C...
