Description

Parasol using photochromic pigments

The present invention relates to an umbrella for mass production using a light pigment.

Photochromic pigments are substances whose molecular structure changes by absorbing light energy of a specific wavelength. Therefore, when the energy applied to this material is stopped, it has the property of reversibly returning to the previous molecular structure. Specifically, when the absorption amount of ultraviolet light increases, the ring structure in the molecule becomes a conjugated structure, and the wavelength of the reflected light changes to change the color. It has the reversible property of returning to color.

In the case of an inorganic optical pigment composed of inorganic substances such as metal oxide, alkaline earth metal, mercury compound, and transition metal compound, the optical pigment is very stable to external environments such as ultraviolet rays, oxygen, and solvents, but is very difficult to process. There was a problem that it was difficult to use.

On the other hand, in the case of organic optical pigments such as benzopyran, naphthopyran, spiropyran, spirooxazine, pulgimid, diarylethene, and azo compound, it is easy to use by dissolving or powdering in a solvent, but UV rays, etc. The molecular structure is unstable due to environmental variables such as light, oxygen, acid, and organic solvents contained therein, and there is a problem in that durability and weather resistance are insufficient.

In order to solve this problem, various conventional methods have been proposed. For example, US Patent Publication US4166043A discloses a method for encapsulating an organic luminous pigment, and US Patent Registration US6740699B2 discloses encapsulation by polymerization using mini-emulsion polymerization of acrylic and methacrylic monomers and luminous pigments in an aqueous emulsion. A method for preparing an emulsion in which the concentration of a photochromic dye does not change for several months is known by mixing and polymerizing an olefin-based compound such as , methylbutenol, chlorohexane, and the like.

However, in this method, when the light pigment is dispersed in a binder, etc., the characteristic expression does not occur properly. In the case of the encapsulation method using a monomer, the polymerization process is complicated and the concentration of the light pigment cannot be sufficiently increased. do.

Since the color of these optical pigments changes as the wavelength of reflected light changes according to the amount of ultraviolet absorption of sunlight, when applied to mass production, such as dyeing and coating, initially Various technologies for mass production using visible pigments have been proposed because it has the advantage of being able to visually compare and grasp the amount of irradiated ultraviolet rays even in normal times.

However, when using the parasol as an umbrella in rainy weather, durability and weather resistance are significantly reduced due to chemical modification such as oxidation by water and physical modification due to strong pressure in rainy weather, so that the properties rapidly decrease as it is used repeatedly. A difficult problem exists.

In addition, when a light pigment is coated on a substrate such as mass production using a general high-temperature coating method, residual stress is generated due to a large difference in the coefficient of thermal expansion between the substrate and the deposition material (visible pigment), and the stability of the deposition layer is lowered. There is still a problem that durability and weather resistance are deteriorated.

US Registered Patent US6740699B2

It is an object of the present invention to provide an umbrella for mass production using a light pigment that can effectively compare and grasp the UV index by visually observing the amount of UV light along with UV protection properties even though it is used repeatedly for a long period of time. Therefore, when it is used as an umbrella in the rain as well as in the case of mass production, it is possible to solve the deterioration of durability and weather resistance due to the problems of chemical transformation such as oxidation by water and physical transformation due to strong pressure in the rain.

It is also an object of the present invention to solve the problem that when the optical pigment is dispersed in a binder, etc., the characteristic expression of the optical pigment does not occur properly.

The present invention is to provide a mass production combined umbrella manufacturing method using a light pigment, comprising the step of depositing a powder containing a light pigment on the surface of a substrate made of a polymer by an aerosol deposition method, and an umbrella for mass production using the same.

In an example of the present invention, in the method for manufacturing an umbrella for mass production using a light pigment, polyimide or Teflon is used after the step of depositing a powder containing a light pigment on the surface of a substrate made of a polymer by an aerosol deposition method. It may further include a thick film coating step of depositing on the material deposition layer.

Due to the application of the aerosol deposition method to the mass-production umbrella using the light pigment of the present invention, when it is used as an umbrella in rainy weather, chemical denaturation such as oxidation by water and physical denaturation due to strong pressure in the rain. There are advantages to minimization.

In addition, the umbrella for mass production using the light pigment of the present invention is applied by an aerosol deposition method, there is no change in composition between the starting material and the formed deposition layer, so there is no side effect on characteristic expression, and the process is performed at room temperature or low temperature below room temperature. Accordingly, there is an advantage in that durability and weather resistance are further improved because it is possible to prevent a problem of stability deterioration caused by high temperature.

In addition, the umbrella for mass production using the light pigment of the present invention does not require the use of dispersing the light pigment in a binder, etc., thereby preventing the problem that the characteristic expression does not occur properly.

In addition, since the mass production umbrella using the light pigment of the present invention is further subjected to a thick film treatment process, it is possible to minimize the problem of deterioration of the expression of the light pigment properties even in strong physical stress such as folding as well as chemical stability.

Hereinafter, with reference to the accompanying drawings, a mass-produced umbrella using the light pigment of the present invention will be described in detail.

Unless otherwise defined in technical and scientific terms used in the present invention, it has the meaning commonly understood by those of ordinary skill in the art to which this invention belongs, and the subject matter of the present invention is unnecessary in the following description. Descriptions of known functions and configurations that may be blurred will be omitted.

In addition, in the present invention, the unit of % used unclearly without special mention means % by weight.

The present invention is to provide a mass production combined umbrella manufacturing method using a light pigment, comprising the step of depositing a powder containing a light pigment on the surface of a substrate made of a polymer by an aerosol deposition method, and an umbrella for mass production using the same. In the case of using this aerosol deposition method, it does not proceed at high temperature and does not use a separate binder, so even if a coating layer is formed using a light pigment having relatively low chemical stability, it does not affect the structure and properties of the compound as well as physical Problems such as peeling of the coating layer due to force also have a surprising effect that does not occur in a general use environment.

In one embodiment of the present invention, the average particle diameter of the powder is not limited within the range capable of achieving the object of the present invention, but may be 0.1 to 100 μm. When the above range is satisfied, the deposition layer may be formed as a denser film, and the deposition layer formation rate or uniformity of the deposition layer decreases, so that the visual pigment properties are deteriorated by physical forces such as stress and pressure caused by folding. problems can be minimized.

In an example of the present invention, in the method for manufacturing an umbrella for mass production using a light pigment, polyimide or Teflon is used after the step of depositing a powder containing a light pigment on the surface of a substrate made of a polymer by an aerosol deposition method. It may further include a thick film coating step of depositing on the material deposition layer. If the thick film layer is formed on the optical pigment deposition layer through the thick film coating step, durability and weather resistance can be further improved, so that the optical pigment properties are more improved even with physical forces such as stress and pressure caused by folding, rain, etc. can be maintained in the long term. The deposition layer of the optical pigment means that the powder containing the optical pigment is formed on the surface of the substrate by aerosol deposition on the surface of the substrate made of a polymer.

In an example of the present invention, the thickness of the thick film layer formed on the optical pigment deposition layer in the thick film coating step is not limited within the range capable of achieving the object of the present invention, but may be 10 to 500 μm. . When the above range is satisfied, it is possible to prevent a problem of lowering the UV reaction rate of the lower optical pigment deposition layer due to excessive thickness, and also to minimize deterioration in durability and weather resistance due to insignificant thickness.

In one example of the present invention, the powder is not limited, and may be manufactured through one or more milling steps. The average particle diameter of the powder can be controlled through the milling process (milling speed, milling time, number of milling, etc.).

In an example of the present invention, the method for manufacturing an umbrella for mass production using a light pigment repeats the step of depositing the powder containing the light pigment on the surface of a substrate made of a polymer by an aerosol deposition method two or more times. may include more. When the above steps are repeated two or more times, the thickness of the deposition layer may be further increased, and durability and weather resistance may be further improved.

In an example of the present invention, the milling may include milling the powder with a ball of 3 to 15 mm for 2 to 8 hours.

In an example of the present invention, the milling may further include milling the powder with a ball of 1 to 5 mm for 4 to 16 hours after milling the powder with a ball of 3 to 15 mm for 2 to 8 hours. can When the powder is manufactured by sequentially performing such a multi-step ball mill method, the optical pigment deposition layer deposited through the step of depositing the powder containing the optical pigment on the surface of the polymer-made substrate by an aerosol deposition method is more It is stable, more dense, and adhesion to the substrate may be further improved. Therefore, the mass-produced umbrella manufactured through the above steps can minimize the problem of deterioration of the visual pigment properties due to physical forces such as stress or pressure during rain or folding.

In an example of the present invention, milling the powder with a ball of 3 to 15 mm for 2 to 8 hours may be performed at 50 to 500 rpm, and milling with the ball of 1 to 5 mm for 4 to 16 hours The step may be performed at 200 to 700 rpm, but the present invention is not limited thereto, and it is not limited because it may be adjusted according to environmental variables, conditions, and the like.

In one embodiment of the present invention, the step of depositing the powder containing the optical pigment on the surface of the substrate made of the polymer by an aerosol deposition method includes the steps of placing the substrate in the deposition chamber after introducing the powder into the aerosol chamber; It may include mixing the powder and the carrier gas to form an aerosol and spraying the aerosol on the surface of the substrate.

As a specific example, in the step of depositing the powder containing the optical pigment on the surface of the substrate made of polymer by an aerosol deposition method, the substrate is seated on a stage that can move in any of three-dimensional directions, the speed of the substrate, The thickness of the deposition layer may be controlled by the number of reciprocations of the substrate. In addition, since the aerosol deposition method is known, a known aerosol deposition method may be used.

In one example of the present invention, in the step of mixing the powder and the carrier gas to form an aerosol, the powder and the carrier gas are mixed to form an aerosol by supplying the carrier gas transported inside the aerosol chamber into which the powder is put. In this case, the carrier gas is preferably air, oxygen, nitrogen, helium, argon, and a mixed gas thereof, but the type of the carrier gas is not limited because it is not a major variable in the aerosol process.

In addition, the carrier gas is introduced into the deposition chamber, the pressure in the deposition chamber is not limited within the range that can achieve the object of the present invention, but it is preferable to maintain it not exceeding a certain range using a vacuum pump, for example, 0.07 Keeping below atm can be exemplified. When the pressure in the above range is maintained, the particles are not sufficiently accelerated, so that the kinetic energy of the particles is reduced, thereby minimizing problems such as having a non-uniform distribution or a non-uniform density.

Also, after transferring the aerosol inside the aerosol chamber to the nozzle, the method may include dispersing and spraying the aerosol through the nozzle to have an appropriate distribution on the substrate located inside the deposition chamber.

In an example of the present invention, the step of spraying the aerosol on the surface of the substrate may include the step of accelerating the powder at 50 to 500 m/s. Specifically, the powder inside the aerosol chamber is introduced together with the carrier gas, and when it is performed at the speed in the above range, the kinetic energy of the particles is not sufficient, so that the phenomenon that the coating layer is formed thinly or is not formed properly can be minimized. Also, it may be more efficient to reduce the manufacturing cost.

In one embodiment of the present invention, the average diameter of the aerosol may mean a state in which fine particles of 0.1 to 100 μm and a gas are mixed.

In one embodiment of the present invention, the temperature performed in the step of depositing the powder containing the optical pigment on the surface of the substrate made of the polymer by an aerosol deposition method is 0 to 40 ℃, preferably 10 to 35, more Preferably, it may be 15 to 30°C. When the process is performed in the above range, the deposition rate is reduced and the manufacturing process is increased, or the problem that the durability of the deposition layer is deteriorated due to non-uniform distribution can be minimized. .

In an example of the present invention, the thickness of the deposition layer formed on the surface of the substrate by depositing the powder containing the optical pigment on the surface of the substrate by an aerosol deposition method may be 0.1 to 500 ㎛. When the above range is satisfied, the adhesion between the deposition layer and the substrate is lowered, thereby minimizing the problem of lowering durability and weather resistance.

In one embodiment of the present invention, the optical pigment is a compound having UV discoloration that changes to a colored state capable of exhibiting dichroism when irradiated with UV light, and any compound having a known UV discoloration property can be used without limitation. . Examples of the optical pigment include spiropyran-based compounds, spirooxazine-based compounds, diarylethene-based compounds, fulgide-based compounds, naphtopyran-based compounds, or a mixture of two or more thereof.
