Embodiment 1

[0056] This example provides a self-cleaning nanometer water-based UV UV curable varnish. The specific preparation process is as follows: first pour 65kg of fluorine-modified water-based polyurethane dispersion BER101 into the dispersion kettle, then pour 0.3kg of defoamer BYK024, 0.2kg Wetting agent twins4100, 0.2kg leveling agent BYK333 are pre-mixed evenly, and slowly added to the dispersion container under stirring, slowly adding 1kg of nano-titanium dioxide, adding 0.4kg of thickener RM2050D to adjust to a suitable viscosity, and dispersing at high speed for 15 minutes , use a 100μm fineness meter to check that the fineness is qualified and there is no oil shrinkage, then slowly add 2kg of water-based photoinitiator IHT-PI659 dissolved with 2kg of film-forming agent dipropylene glycol butyl ether DPNB, and disperse at a medium speed (1500 rpm / Minutes or more) for 10-15 minutes, use a 100μm fineness meter to check the fineness and no oil shrinkage, add 28.9kg of deionized ...

Embodiment 2

[0058] This example provides a self-cleaning nanometer water-based UV UV curable varnish. The specific preparation process is as follows: first pour 72kg of fluorine-modified water-based polyurethane dispersion BET101 into the dispersion kettle, then pour 0.6kg of defoamer BYK028, 0.4kg Wetting agent BYK346 and 0.3kg leveling agent BYK336 are pre-mixed evenly, and slowly added to the dispersion container under stirring, slowly adding 2kg of nano-titanium dioxide, adding 0.5kg of thickener RM-12W to adjust to a suitable viscosity, and then dispersing at a high speed After 15 minutes, use a 100μm fineness meter to check that the fineness is qualified and there is no oil shrinkage, then slowly add 2.5kg of water-based photoinitiator IRGACURE2959 dissolved in 3kg of film-forming agent ethylene glycol monobutyl ether, and disperse at a medium speed ( 1500 rpm or more) for 10-15 minutes, use a 100μm fineness meter to check that the fineness is qualified and there is no oil shrinkage,...

Embodiment 3

[0060] This embodiment provides a self-cleaning nanometer water-based UV UV curable varnish, and its specific preparation process is as follows: first pour 80kg of acrylic acid dispersion into the dispersion kettle, and 0.4kg of defoamer, wherein 0.3kg of defoamer tego810 and 0.1kg defoamer tego902w, 0.4kg wetting agent BYK349, 0.4kg leveling agent tego450 are pre-mixed evenly, slowly added to the dispersion container under stirring, slowly added 0.5kg nano-titanium dioxide, and 0.5kg thickener R299 After adjusting to a suitable viscosity, disperse at high speed for 15 minutes, use a 100μm fineness meter to check that the fineness is qualified and there is no oil shrinkage, after dissolving 2kg of water-based photoinitiator IHT-PI659 with 3kg of film-forming agent dipropylene glycol methyl ether Add slowly, disperse at a medium speed (above 1500 rpm) for 10-15 minutes, use a 100μm fineness meter to check that the fineness is qualified and there is no oil shrinkage, add 11.9kg o...

Abstract

The invention discloses a self-cleaning water-based UV ultraviolet curing varnish. The varnish comprises the following components in parts by weight: 60-85 parts of a dispersion, 0.3-0.7 part of a defoaming agent, 0.2-0.5 part of a wetting agent, 0.1-0.7 part of a flatting agent, 0.1-3 parts of a nano assistant, 2-3 parts of a water-based photoinitiator, 0.2-1 part of a thickening agent, 2-4 partsof a film-forming agent and 1-30 parts of water, wherein the dispersion is a water-based fluorine modified polyurethane dispersion or acrylic dispersion which needs ultraviolet light curing, and thenano assistant is nano titanium dioxide. The varnish provided by the invention has the advantages of high curing hardness, good toughness, good abrasive resistance, easy cleaning, capability of purifying the surrounding environment, greenness, environment friendliness, energy conservation and the like, can be applied to coating of decorative glass, solid wood furniture, plate furniture and indoorwood floors, and has an excellent application effect.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a self-cleaning water-based UV curable varnish for coating decorative glass, solid wood furniture, panel furniture and indoor wooden floors and a preparation method thereof. Background technique [0002] In recent years, UV curable coatings have developed rapidly, and its main advantages are fast curing, low energy consumption, excellent performance of the cured paint film, and high production efficiency. However, with the deep application of UV curable coatings in various fields, its own shortcomings are gradually exposed: 1. The diluent monomers used are a little volatile, which will become VOC emissions, causing harm to workers and polluting the environment; 2. The initiator used will produce toxic and harmful substances such as benzaldehyde after decomposition, causing harm to workers and polluting the environment; 3. Most of the diluted monomers used a...
