preparation example Construction

[0041] The preparation of nano-anion slurry is: nano-anion powder: hydroxyethyl methacrylate = 1:4, first add hydroxyethyl methacrylate in the reaction kettle, and slowly add nano-anion powder and dispersant under stirring state, control Warm at 50-60°C for 3 hours. Wherein the dispersant is a special nanometer dispersant which belongs to the macromolecule anion type, and its consumption is 5-8% of the negative ion powder. Then refine to a fineness of less than 10um.

[0042] The negative ion powder is: nano-scale iron magnesium tourmaline powder, terbium oxide, twelve calcium fourteen aluminum oxide, coral fossils; opal; serpentine; a mixture of at least two kinds of medical stone. Preference is given to a mixture of ferrite powder, terbium oxide, and opal.

[0043] The UV oligomer is one or a mixture of several oligomers in bisphenol A epoxy acrylate, urethane acrylate, amino acrylate and polyester acrylate. Among them, bisphenol A epoxy acrylate and urethane acrylate are...

Embodiment 2

[0050] Pump the above components 1, 2, and 4 into the reactor, heat, add 50% of the catalyst at 65°C, control the temperature at 100-105°C until the acid value is less than 1.0mgKOH / g, then add the rest of the catalyst After 20 minutes of reaction, the temperature can be lowered to 80°C and the material can be discharged. The PE related indicators: viscosity 80-200mpa.s / 60℃; AV<1.0mgKOH / g. The preparation MF of embodiment 2 nano negative ion slurry

Abstract

The invention relates to a negative ion coating capable of being cured by ultraviolet light and a preparation method of the negative ion coating. The negative ion coating is a composition capable of being cured by ultraviolet light, and comprises an oligomer, a dilution monomer, halogenated acrylate, an initiator, nano negative ion slurry, and a coating additive, wherein the dosage of the halogenated acrylate is 10 to 15 percent; the halogenated acrylate is a reaction product of epoxy chloropropane, methacrylic acid and a catalyst; the catalyst is, but not limited to, quaternary ammonium salt such as benzyl triethyl ammonium chloride and tetrabutylammonium bromide; the dosage of the catalyst is 0.2 to 0.3 of the total weight of the epoxy chloropropane, the methacrylic acid and the catalyst; the dosage of the nano negative ion slurry is 15 to 25 percent; the nano negative ion slurry is obtained by mixing nano negative ion powder with methacrylic acid hydroxyethyl under the existence of a special dispersing agent, stirring and carrying out temperature control at 50 to 60 DEG C for 3 hours; when the coating quantity reaches 40g / m<2>, the negative ion generation quantity of the composition is equal to or higher than 2000 / m<3>.

Description

technical field [0001] The invention belongs to the field of UV (ultraviolet light curing) coating preparation, and the invention particularly relates to a preparation method of an ultraviolet light curing negative ion coating. Background technique [0002] Negative ions can not only promote the synthesis and storage of vitamins in the human body, but also strengthen and activate the physiological activities of the human body, so it is also called "air vitamin". , such as after a thunderstorm, the negative ions in the air increase, and people feel comfortable. In the air-conditioned room, because the negative ions in the air almost disappear after a series of air-conditioning purification treatments and long ventilation ducts, people will feel chest tightness, dizziness, fatigue, and decline in work efficiency and health when they stay in it for a long time. syndrome". In the medical field, negative ions are recognized as an effective means of killing germs and purifying t...
