Description
Technical field
The invention belongs to paint field, especially a kind of aluminum ceiling coating and preparation method thereof.
Background technique
Aluminum ceiling conduct-kind new decorative material is developed certainly since its weight per unit area is light, relative intensity
Height, easily manufactured and installed, the service life is longer, and it is non-aging sink, color-changeable shape-changeable so obtain very universal application,
And application amount increases year by year, becomes people and fits up essential product.
With the development of aluminum-pinch, application is more and more extensive, using from kitchen and toilet gradually to parlor, the day in room
Flower decoration, thus various function tops are arisen spontaneously.Expanding economy pushes the raising of people's environmental consciousness, environmental quality issues
The extensive concern of people is received, consumer also results in interior while the use of a large amount of finishing materials improves quality of the life
The continuous deterioration of air quality, the harm to human body, the harm of especially poor to resistance old man, children and pregnant woman,
Hot issue as concern.
Aluminium ceiling decoration coating is both at home and abroad always using thermosetting solvent based coating, when thermosetting solvent based coating is because of production
Between produce, specific productivity is low, have the use of a large amount of solvents in addition, not only not environmentally but also relatively safety, restrict functional form aluminium day always
Colored development.And existing painting layer function is relatively simple, and some only reaches temporary antifouling effect by using additive, in short-term
It is interior to fail；Some adds some active anion generators to discharge anion, it has not been convenient to, being also not suitable for high-volume makes
With；Some does thermosetting solvent-based coating by being simply added into negative ion powder.It is multi-functional in all directions that it is not able to satisfy existing people
Demand.
Summary of the invention
In order to solve prior art problem, the present invention provides a kind of aluminum ceiling coating, is only irradiated by UV light, energy
Rapid curing, solvent-free volatilization, coating is fine and close, binding force is excellent, solvent resistant, environmentally protective, oil rub resistance is anti-graffiti, absorbing formaldehyde removes
Bacterium and have negative ion-releasing function.
To achieve the above object, technical solution provided by the present invention is：A kind of aluminum ceiling coating, feature exist
In it is made of the raw material below according to parts by weight, and specific formula is：
The present invention also provides a kind of preparation methods of above-mentioned aluminum ceiling coating, which is characterized in that includes the following steps：
S1：By formula by 30-40 parts of fluosilicic modification acrylates, 10-20 parts of dipentaerythritol hexaacrylates and 10-20
The modified double pentaerythritol methacrylate of part 6-caprolactone is put into reaction vessel；Use blender with 1000-1500 turn/
The revolving speed of minute stirs 15-30 minutes；
S2：Add 20-30 parts of Tourmaline powders and 10-20 parts of group of the lanthanides light rare earths；Use blender with 2000-3000 turn/
High-speed stirred 30-60 minutes minute；
S3：Add 2-4 parts of 2,4,6- trimethylbenzoy-dipheny phosphine oxides, the bis- (2,4,6- tri- of 2-4 parts of phenyl
Methyl benzoyl) phosphine oxide, 1-2 parts of fluorinated diphenyl titanium cyclopentadienyls, 0.5-1 parts of defoaming agents and 0.5-1 parts of levelling agents；Using stirring
Machine is stirred 15-30 minutes with 1000-1500 revs/min of revolving speed；
S4：Average grain diameter is ground to no more than 5 microns using sand mill.
Preferably, the defoaming agent is BYK055 defoaming agent, and the levelling agent is BYK333 levelling agent.
Preferably, the group of the lanthanides light rare earth is group of the lanthanides cerium group rare-earth.

Preferably, the blender used in the step S1 and S2 is that Dongguan benefit is risen the production of intelligent Equipment Limited
FS30 twin shaft frequency control dispersion machine.
Preferably, the grinder used in the step S4 rises what intelligent Equipment Limited produced for Dongguan benefit
LTD2015E high-efficiency sand grinder.
Required gloss can be reached in coating of the invention by adding dumb light powder, such as the amount of OK520 (with 60 degree of angles
Vancometer survey the glossiness on surface, professional standard:HG/T2597-94 bloom >=88 zero diopters:40-60 matt:15-40 without
Light:≤5).
Aluminum ceiling coating of the present invention can be by the way of aluminum ceiling silk-screen, offset printing or roll marks decorative pattern
Coated on aluminum ceiling；Three kinds of mode of printings can single use a variety of can also reuse；Aluminum ceiling outermost surface
Roller coating aluminum ceiling coating, then solidified using UV lamp, solidification energy uses 150-500MJ/CM3.
The mechanism of action of the invention：
A, coating generates the mechanism of anion：
Anionic additive with natural minerals Tourmaline powder (tourmaline powder) be main raw material(s), while in proportion addition can
The group of the lanthanides cerium group rare-earth for increasing releasing effect mixes, and is added in UV coating and makes it have permanent release anion
Function, release anion reach 1500-50000/cm3.First of the product to releases such as indoor various decorating and renovating materials, furniture
Aldehyde, ammonia, benzene, TVOC etc. are toxic, pernicious gas has effect of dispelling, and elimination factor is greater than 90%, and degerming rate is greater than 90%, thus assign
Give air-cleaning function.Coating solidifies butt Ma by the way that Tourmaline powder and group of the lanthanides light rare earth are added in formula as filler material
Beautiful jade powder and group of the lanthanides light rare earth are blended in ink coating, using Tourmaline powder and group of the lanthanides light rare earth cooperation long-acting efficient release bear from
Son.
B, the anti-graffiti mechanism of coating anti-pollution：
Coating cooperates high crosslink density monomer (high functional group (3-9) by the way that fluosilicic modification acrylate is added in formula
Monomer), fluosilicic ion concentrates on ink coating superficial layer after solidification, and the low-surface-energy that is formed modified in conjunction with fluosilicic, is formed
The coating of nano surface micro-rough structure, low-surface-energy achievees the purpose that anti-pollution is anti-graffiti just as lotus leaf effect.
The present invention has the advantages that：
Coating environment-friendly high-efficiency of the invention, coating transparent do not influence color, can divide dumb light, highlight coating；It is multiple functional,
Antifouling anti-pollution, is tested by oil pen, and same point can achieve 100 times or more；Anion is generated, through professional anionic textiles instrument
It is 1500-50000/CM3 that KEC900, which measures anion average measurement value,；Harmful substance, dispelling abnormal flavor, potent sterilizing are reduced,
Product, which has the toxic, pernicious gases such as formaldehyde, ammonia, benzene, the TVOC of releases such as indoor various decorating and renovating materials, furniture, dispels
Effect, the test through Guangzhou Institute of Analysis, elimination factor are greater than 90%, and degerming rate is greater than 90%.
