A kind of method of the aqueous light diffusion coating preparing above-mentioned environmental protection, including following preparation process:
(1) weigh each component by above-mentioned weight portion, the diluent of light diffusing agent and 20%-30% is placed in and grinds
Being ground pre-dispersed in grinding machine, described milling time is 25-35min, and machine rotating speed is 1000-1500r/min,
Mixture is obtained after grinding；
(2) mixture of gained in resin, auxiliary agent, remaining diluent and step (1) is placed in turn
Speed be 100-300r/min agitator in stir 1-1.5h, obtain environmental protection aqueous light diffusion coating.
The optical film material of a kind of aqueous light diffusion coating being coated with above-mentioned environmental protection or sheet material.
Water paint is based on water-base resin, the coating prepared for medium with water, has toxicity little,
The advantage such as nonflammable, free from environmental pollution, energy-conservation, safe, the most also has some of solvent based coating
Performance, its coating hardness is high, and adhesive force is strong, pliability good.
Organosilicon light diffusing agent, belongs to the light diffusing agent of organic, is a kind of with siliconoxygen bond connection, three-dimensional
The polymer microballoon of stereochemical structure, this light diffusing agent, originally as a kind of white powder, adds different material
In the resin of matter, can be uniformly dispersed in matrix with a kind of trickle clear glass spheroid, by with not
With the difference of the refractive index of base material, the carrying out of light source penetration reflects, and changes the course of light, reaches
Even light and the purpose of printing opacity, meet the demand of haze value and light transmittance simultaneously.
Polymethyl methacrylate (PMMA), is one of best plastics of light transmission, light transmittance up to
92%, may match in excellence or beauty with optical glass, and its hardness is high, high temperature plasticity is good, is preferable light scattering material
Material matrix.
Glass microballoon, is processed through high-tech by borosilicate raw material, and granularity is 10-250 micron, wall
Thick 1-2 micron.It is excellent that this product has light weight, low heat conduction, higher intensity, good chemical stability etc.
Point, its surface has oleophyllie hydrophobic performance through special handling, is very easy to be scattered in organic material system
In.
Defoamer, also referred to as anti-foam agent, be reduction surface tension in food processing process, and suppression foam produces
Raw or elimination has produced the food additive of foam.China is permitted spendable defoamer emulsified silicone oil, height
Carbon polyol fatty acid ester complexes, polyoxyethylene polyoxypropylene tetramethylolmethane ether, polyoxyethylene polyoxy Propanolamine
Ether, polypropylene glycerol aether and polyoxyethylene polyoxypropylene glycerin ether, polydimethylsiloxane etc. 7 kinds.
Levelling agent, English major name: (Leveling agent), levelling agent is a kind of conventional coating
Auxiliary agent, it can promote coating to form a film smooth, smooth, uniform during drying and forming-film；
Can effectively reduce covering with paint liquid surface tension, improve a class material of its levelability and uniformity；Painting can be improved
The permeability of decorations liquid, produces speckle and the probability of spot when can reduce brushing, increases spreadability, make into
Film is uniform, natural.Mainly surfactant, organic solvent etc..Levelling agent is roughly divided into two big classes.
A kind of working by adjusting paint film viscosity and flow time, this kind of levelling agent is that some are high mostly
The organic solvent of boiling point or its mixture, such as isophorone, DAA, Solvesso150 etc.；Another
Planting and worked by adjustment coating surface character, the levelling agent described in general people refers to this mostly
One class levelling agent.This kind of levelling agent migrates to coating surface by the limited compatibility, affects paint film interface
The surface naturies such as tension force, make paint film obtain good levelling.According to the difference of chemical constitution, this kind of levelling
Agent mainly has a three major types: acrylic compounds, silicone and fluorocarbons class.
Thixotropic agent has thixotropy, and thixotropy refers to that, when grease is sheared, denseness diminishes, and stops cutting
When cutting, the character that denseness increases again.Thixotropy thixotropy also known as shakes change, is that gelinite is in vibration, pressure
The lower reversible colloidal sol phenomenon occurred of effect of mechanical force such as compel.Thixotropic agent i.e. adds can make resin in resin
Glue has higher denseness when static, becomes the most again the material of low denseness fluid.At present
Commonly use is 4 big classes, aerosil, organobentonite, castor oil hydrogenated, polyamide wax.
Wetting agent is to make solid material be more easy to the material being soaked in water, by reducing its surface tension or boundary
Surface tension, allows the water to be deployed on solid material surface, or penetrates its surface, and solid material moistening.
It is typically some surfactants, such as sulfonated oil, soap, Nekal BX etc., it is also possible to soybean lecithin,
Thio-alcohol, hydrazides class and mercaptan acetals etc..
Beneficial effects of the present invention: the present invention has light superelevation light transmittance, different-grain diameter by interpolation
Diffusant, will occur diffraction, diffraction, the incident ray that reflects, reflect or scatter to carry out efficient combination,
To realize the diffusion of light as far as possible, greatly improve light transmission and the light diffusion effect of the present invention, increase
Add the briliancy of light, it is achieved the uniformly light-emitting of light source, eliminate the glare problem of point light source light-emitting；Use
Environment-friendly water-based system, it is to avoid the dicyandiamide solution pollution to environment, greatly reduces the discharge of VOC
Amount, improves the safety of the present invention；The interpolation of various auxiliary agents makes the present invention have good adhesive force；
Present invention process is simple, easy to operate, it is simple to produce and use.
