TECHNICAL FIELD The present invention relates to a coating material containing perl having functions of infrared rays, ultraviolet ray blocking, sight blocking and discoloration, a multi-layer shielding and discoloring film using the same, and a method of manufacturing the same.
Window film applied to buildings and windows focuses on blocking ultraviolet (150 ~ 380nm), visible (380 ~ 780nm) and infrared (780 ~ 2300nm) areas depending on the wavelength of sunlight. Development has been concentrated.
In the case of window film, shielding function, which is another product use, has been highly dependent on metal reflection using an aluminum deposition (CVD) film and a sputter film. As a result, due to electromagnetic wave shielding by metal materials, There is a problem that a device may malfunction or a car accident may occur due to electromagnetic wave reflection.
Another function of window film is to use discoloration film for discoloration. A color-changing film is a film whose color changes according to viewing angle, and refers to a film that changes into various colors such as yellow, red, and green depending on incident angle of sunlight. The current 3M discoloration film is manufactured by making a thin PET film by stacking 100 ~ 300 layers and attaching at once. In the currently commercially available discoloration film, when a plurality of folds (100 to 300) of the fabric are overlapped, even if a small foreign object is included in the process, there is a problem that the quality of the fabric is bad and the price is extremely high.
Also, to date, pearl has been mainly used in opaque deco films. The reason for this is that the haze is generated according to the content of pearl and the resin, and when the pearl in the powder state is mixed with the adhesive layer, the pearl particles are initially dispersed evenly, but only the pearl particles fall down over time.
In contrast, Korean Patent No. 10-0847342 discloses a decorative sheet having a diffuse reflection function using pearls, but the pearl content is about 30 to 40%, which is costly. Korean Patent No. 10-105024 discloses an invention relating to a method for producing a functional forge having excellent thermal photo-acoustic shielding ability using pearl, but it is required that 1 to 50 parts by weight of pearl particles are used and a perl containing layer is formed in a synthetic resin, Which is difficult to use as a coating film on automobile glass.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which: . Other objects, features, and advantages, including the objects, effects and advantages of the present invention will become more apparent from the description of the preferred embodiments.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view of a shielding and discoloring film using a pearl according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a multi-layer structure of a shielding and discoloring film using a pearl according to an embodiment of the present invention.
1, a shielding and discoloration film containing pearl according to the present invention is composed of a clear hard infrared
The shielding and discoloration function of the pearl-containing shielding and discoloring film according to the present invention is characterized by being formed in the perl coating and the multi-layer perl coating (50, 52).
The pearl coating and the multi-layered pearl coating (50, 52) of the present invention are distinguished by the fact that they include pearl. Conventionally, when the pearl is mixed with a coating agent to coat the film, the pearl powder is hardly deposited and the pearl is hardly contained in the coating agent. However, according to the present invention, the pearl powders are not settled by the mixing ratio of the coating agent and the coating method, and the uniform distribution of the coating agent can be maintained. Hereinafter, a coating agent containing pearl is described.
The pearl coating agent (50) and the multi-layer pearl coating agent (52) comprise 12 to 40 parts by weight of a coating agent, 48 to 87 parts by weight of an organic solvent, a curing agent and a pearl microparticle.
It is preferable to use 12 to 40 parts by weight of the coating base as a constituent with respect to the total weight of the pearl coating agent (50) and the multi-layer pearl coating agent (52). When the base of the coating agent is 12 or less, it is difficult to obtain a smooth surface in a state in which the pearl is uniformly dispersed, and it is difficult to obtain smoothness during coating because of the reduced amount of the base material of the coating agent. The time required for the dispersion itself during the dispersion of the pearl is long due to the high viscosity, and when the process is applied, the high viscosity may cause the surface roughness and the microgravure coating to form a cluster.
The organic solvent for the shielding and discoloration films is preferably 48 to 87 parts by weight. If the amount of acetone in the above organic solvent is 10 parts by weight or more, uncooling may occur due to the coating phenomenon.
The curing agent of the shielding and discoloration film includes at least one of isocyanate, epoxy, and metal chelate.
The coating agent according to the present invention is composed of 12 to 40 parts by weight of a coating agent, 48 to 87 parts by weight of an organic solvent, a curing agent and a pearl microparticle, wherein the coating agent base comprises 5 to 20 parts by weight of butylacrylate, 10 to 30 parts by weight of methacrylate, 1 to 10 parts by weight of acrylic acid, 1 to 10 parts by weight of methacrylic acid, 0.2 to 2 parts by weight of 2-hydroxyethyl acrylate, 0.2 to 2 parts by weight of glycidyl acrylate, 0.1 to 1 part by weight of acrylamide and 0.1 to 2 parts by weight of pearl-shaped synthetic pearls or natural pearls mixedly or singly. The organic solvent is composed of 50 parts by weight of acetic acid, And 1 to 5 parts by weight of ethyl alcohol, wherein the curing agent comprises 0.1 to 5 parts by weight of at least one of epoxy or metal chelate, Euki can prevent the generation of haze and maintain a constant dispersion state.
The above acrylate is an acrylate monomer.
The above butyl acrylate, methacrylate, 2-ethylhexyl acrylate, acrylic acid, 2-hydroxyethyl acrylate, glycidyl acrylate and acrylamide are used as the pressure sensitive adhesive. Acetic acid, acetone, ethyl alcohol and methyl ethyl ketone were used for the reaction removal and dilution.
The tabular synthetic pearl or natural pearl contained in the pearl coating agent of the blocking and discoloring film is preferably 0.5 part by weight or more and 2 parts by weight or less. When the tabular synthetic pearl and natural pearl are added in an amount of 0.5 parts by weight or less, the discoloration and shielding effect is poor. When the amount is 2 parts by weight or more, the basic performance of the window film is poor.
The above-mentioned synthetic pearl and natural pearl in a plate form plays a role of imparting a discoloring effect and a shielding effect. The discoloration effect means that the color looks different depending on the viewing angle, and the shielding effect is to block the line of sight outside the window to which the film is attached.
The plate-like synthetic pearl and natural pearl have a grain size of 1 to 70 mu m, and when the thickness is less than 1 mu m, the shielding and discoloring films are less effective for shielding and discoloring due to their small particle size. In case of pearl of 70 mu m or more, it may be seen as a foreign matter in coating due to an excessively large particle size or a decrease in visibility. In addition, the pearl-shaped pearl has a greater reflection angle than the spherical pearl, which is advantageous in that it has a shiny effect.
The polymerization and blending process of the perl containing pearl coating agent is as follows.
20 parts by weight of butyl acrylate, 10 parts by weight of methyl acrylate, 7 parts by weight of 2-ethylhexyl acrylate, 3 parts by weight of acrylic acid, 0.1 part by weight of benzoyl peroxide, 50 parts by weight of acetic acid and 7.5 parts by weight of acetone, .
The inside temperature of the reactor is slowly increased by injecting an outer temperature of 75 to 85 ° C into the outer jacket of the metered reactor. When the exothermic reaction starts at the inner temperature of the reactor of 75 ° C, the temperature of the outer jacket is lowered to 35 ~ 45 ° C, and the heat stability is stabilized for 20 minutes. After the heat is stabilized, the temperature of the outer jacket is maintained at 75 ~ 85 ℃ and reacted for 8 hours, followed by natural aging for 8 hours. The prepared pressure sensitive adhesive is preliminarily mixed with a curing agent such as metal chelate, isocyanate, epoxy, and aziridine, MEK (methyl ethyl ketone), and TOL (toluene). The pearl is mixed with MEK at a ratio of 10: 1, and then a predetermined amount of the pearl is dropped into the adhesive in a stirred state for 10 minutes. Thereafter, stirring is continued for 30 minutes.
This process allows the pearl to be distributed uniformly in the coating without sinking.
Hereinafter, a shielding and discoloration film using the pearl according to the present invention will be described.
The shielding and discoloration film using the pearl is a clear hard infrared ray shielding Layered structure is advantageous in terms of heat shrinkage because it is composed of a

(2) clear hard infrared shielding coating layer
5 parts by weight of urethane acrylate, 10 parts by weight of trifunctional acrylate, 6 parts by weight of trifunctional methacrylate, 1 part by weight of titanium oxide, 3 parts by weight of antimony tin oxide, 15 parts by weight of methyl ethyl ketone, 15 parts by weight of toluene One or more of the photoinitiators benzophenone and hydroxycyclohexyl phenyl ketone are mixed to form a clear hard infrared blocking coating layer.
(3) Infrared blocking color adhesive layer
The mixture was mixed with 10 kg of acrylic pressure-sensitive adhesive (MI-07 A & G LAB), 0.1 kg of metal chelating curing agent (CA-5 Hana Ehwa), 6KG of infrared blocking agent (antimony tin oxide), 11KG of methyl ethyl ketone and toluene mixed solvent to obtain 19.24% An infrared blocking adhesive layer is formed.
(4) Shielding and discoloration film using pearl
A polyethylene terephthalate film (PET film) having a thickness of 12 to 69 탆 is used as a base film, and a pearl coating agent is applied to the bottom of the base film to perform pearling and pearling of the discoloration film using pearl. The line speed is 20 to 25 M / MIN using a micro-gravure coater and coated to a thickness of 5 to 8 탆, and cured using a heat chamber.
≪ Test Example 1 >
Using a spectrophotometer (Cary-5000, manufactured by Varian), the shielding effect according to the visible light transmittance of the perl coating was tested.
Referring to the results in Table 1, the shielding effect of Example 1 and the pearl against visible light was tested. The results show that the lower the visible light transmittance, the better the shielding effect by pearl.
≪ Test Example 2 &
The degree of haze according to the pearl content was measured using a HAZE meter.
According to the results shown in Table 2, the shielding effect is improved according to the pearl content, but the visibility due to the increase of the haze is deteriorated. It can be seen that the content of pearl is suitably between 0.5 and 1.0 PART depending on the shielding effect and the degree of haze.
≪ Test Example 3 >
The visibility reduction and haze change according to the particle size of pearl were tested.
In the case of the pearl particles of 0.2 to 1 탆, the increase of the haze due to the diffuse reflection of the pearl results in a decrease in visibility upon visual observation of the film. It is advantageous to use pearl in a state of 1 to 45 mu m in the best use of the pearl, and it is also possible to use a pearl of 45 to 70 mu m. In the case of pearl of 70 μm or more, the particles are seen to be large during visual observation, and this property is apparent because of relatively large haze, but it is difficult to use as a product.
