Embodiment 1

[0036] Embodiment 1: a kind of manufacture method of water-based LEDUV photocurable paint, is characterized in that, comprises the following steps:

[0037] S1. Select water-based polyurethane acrylate emulsion, water-based polyurethane acrylate dispersion, N-vinylpyrrolidone monomer, compound light stabilizer EVERSORBAQ7, LED photoinitiator, 2,4,6-trimethylbenzoyl- Diphenylphosphine oxide, defoamer, wetting agent, leveling agent and deionized water are used as raw materials;

[0038] S2. Weigh an appropriate amount of water-based urethane acrylate emulsion and water-based urethane acrylate dispersion, mix them according to the ratio of 1:5-5:1 by mass, stir evenly, and prepare the composite UV resin raw material, and mix the UV resin raw material Add it into the stirring tank from the feed port;

[0039] S3. Weigh an appropriate amount of LED photoinitiator and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, and mix them according to the mass ratio of 10:1-10:5 to obtain lig...

Embodiment 2

[0049] Example 2: Based on Example 1, the difference is that an appropriate amount of water-based urethane acrylate emulsion and water-based urethane acrylate dispersion is weighed, mixed according to a mass ratio of 1:1, stirred evenly, and added to the stirring In the tank, weigh an appropriate amount of defoamer and wetting agent, and add them to the stirring tank at the ratio of 1.0% and 0.5% of the mass of the composite UV resin raw material added, set the rotating speed of the rotating motor to 20rpm, and stir the stirring motor The speed is 600rpm, the stirring time is 20min, stir evenly, then N-vinylpyrrolidone monomer is added to the stirring tank in the proportion of 10% of the mass of the composite UV resin raw material, and the rotating speed of the rotating motor is set to 20rpm, and the stirring motor The stirring speed is 600rpm, the stirring time is 10min, stir evenly, weigh an appropriate amount of LED photoinitiator and 2,4,6-trimethylbenzoyl-diphenylphosphine...

Embodiment 3

[0051] Example 3: Based on Examples 1 and 2, the difference is that an appropriate amount of water-based urethane acrylate emulsion and water-based urethane acrylate dispersion is weighed, mixed according to a mass ratio of 1:2, stirred evenly, and added In the stirring tank, weigh an appropriate amount of defoamer and wetting agent, and add them to the stirring tank in the proportion of 2.0% and 1.0% of the quality of the composite UV resin raw material added, set the rotating speed of the rotating motor to 30rpm, stir The stirring speed of the motor is 800rpm, the stirring time is 30min, stir evenly, then N-vinylpyrrolidone monomer is added to the stirring tank in the proportion of 20% of the mass of the composite UV resin raw material, and the rotating speed of the rotating motor is set to 30rpm. The stirring speed of the stirring motor is 800rpm, and the stirring time is 15min. Stir evenly, take an appropriate amount of LED photoinitiator and 2,4,6-trimethylbenzoyl-diphenyl...

Abstract

The invention discloses a manufacturing method and manufacturing equipment of a water-based LEDUV light-curing paint, belonging to the technical field of paint preparation. The invention uses UV curing technology LEDUV light source to cure, the light source has a long life, is a cold light source, has no heat radiation, has high energy, uniform irradiation improves production efficiency, does not contain toxic substances, and is safer and more environmentally friendly than traditional light sources; At the same time, the LED light source has both high hardness and chemical resistance of conventional water-based UV coatings, and its excellent film properties make it comparable to solvent-based UV coatings and other solvent-based systems. The composite UV resin raw material has fast curing speed, good hardness, toughness and fullness; the N-vinylpyrrolidone monomer used in the method of the present invention has the fastest curing rate in the single-tube energy-based diluent base, and N-vinylpyrrolidone monomer ‑Vinylpyrrolidone can increase vertical tensile strength, low toxicity and can improve the flexibility of the coating after light curing.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a manufacturing method and manufacturing equipment of a water-based LEDUV light-curing paint. Background technique [0002] UV coatings are ultraviolet photocurable coatings, also known as photoinitiated coatings and photocurable coatings. After coating through equipment construction, the coating film stimulates the initiator to decompose under the irradiation of ultraviolet light, generates free radicals, triggers resin reaction, and instantly solidifies to form a film. Its green, environment-friendly and high-efficiency unique attributes are deeply loved by various consumer groups. Since the 1970s, UV coating technology has been advancing at a super-high speed of development, including EB electron beam, UV-LED in recent years Curing technology has also matured and gradually applied to the market. UV-LED is an ultraviolet light-emitting diode, which is a kind of LED ...
