Description

Foldable door having room-temperature curable Ottchil-coated foldable insect screen

The present invention relates to a folding auxiliary door comprising a room temperature curing type lacquered wrinkle insect screen installed on a window, and more particularly, by coating a room temperature curing type lacquer on the wrinkle insect screen part installed on a window for insect repellency, antibacterial property, sterilization property, electromagnetic wave It relates to a folding auxiliary door including a room temperature curing type lacquered wrinkle insect screen having a blocking function and various colors.

The problem of traditional lacquer lacquer is constant temperature (26-26oC), humidity (70-80% relative humidity), long-time curing (10-30 days), lacquer rise, and lack of color diversity. It was recognized as a realm, and as a result, it was far from the interest of the general public despite its excellent physical and chemical properties. Recently, due to research by companies, companies are emerging that separate urushiol, which is the core component of lacquer liquid, to make multimeric urushiol, and convert it to room temperature curing paint and sell it. These room temperature curing type lacquer paints have the advantages of insect repellency, antibacterial properties, sterilization and electromagnetic wave shielding properties of traditional lacquer, but have the advantage of minimizing the lack of color diversity and lacquer rise, which are traditionally recognized as the disadvantages of lacquer. Room temperature hardening type lacquer is mainly used in the area using wood, but it can be painted on various substrates including metal and plastic other than wood.

Registered Patent 10-1255619 claims a method for manufacturing a lacquered insect screen, but claims that a metal insect screen is used as a base material and a lacquered insect screen is manufactured through a high working temperature and current flow. Also, in the patent, there are wrinkles in the insect screen and there is no information about whether it can be opened or closed.

Registered Utility Model 20-0192856 and Patent Publication No. 10-2020-0012129 claim a folding auxiliary door, but there is no mention of whether the insect screen is lacquered or not.

In the case of the wrinkle insect screen and non-woven honeycomb screen that make up the current folding window, the durability life is short due to corrosion caused by ultraviolet rays and external environment, and it is providing the cause of bacterial growth in residential/commercial spaces by adsorption of pollutants. For natural insect repellency and traditional Korean color expression, room temperature curing type lacquer is to be coated on wrinkle insect repellent net and non-woven honeycomb screen. Here, the description is limited to screens and screens, but it is also possible to apply lacquer coating to the entire folding auxiliary door.

Registered Patent 10-1255619 Patent Publication 10-2020-0012129 Registered Utility Model 20-0192856

The wrinkle insect screen and non-woven honeycomb screen that make up the window are made of general metal and plastic and do not have chemical functionality because they do not undergo separate painting. In order to significantly improve the insect repellency, sterilization, electromagnetic wave blocking function and durability of such window components through the introduction of room temperature curing type lacquer coating, various colors are applied to satisfy the aesthetic demands of modern people.

Brushing and dipping (soaking) a room temperature hardening type lacquer (refined lacquer, water-based acrylic type lacquer, water-based urethane type lacquer) that is naturally dried at room temperature rather than the traditional lacquer drying method (temperature 24-26/humidity 70-80%) and spray method or a method including one or more of them, coating the insect screen or screen, and curing temperature at 10 to 30oC, 40 to 60% relative humidity, and natural drying and curing for 1 hour to 240 hours. It is possible to paint the wrinkle screen or honeycomb screen before attaching it to the folding auxiliary door or after attaching it to the auxiliary door.

The existing wrinkle insect screen and non-woven honeycomb screen composing the window have a natural insect repellent function.

It has sterilization and antibacterial properties that inhibit contamination or bacterial growth due to adsorption of fine dust or other foreign substances.

It significantly lowers the rate of corrosion caused by the surrounding environment, including UV rays or chemicals, and increases the durability of the product.

It helps to create a more comfortable indoor environment due to the electric wave blocking function of the room temperature curing type lacquer.

By applying the various colors unique to the Korean tradition of room temperature curing type lacquer, it is possible to increase domestic demand and exports, and to take various responses more quickly in a rapidly changing era.

Reference numeral 100 denotes a folding auxiliary door, the folding auxiliary door 100 is a metal (aluminum) or plastic handle bar (1) upper rail bar (2) escape prevention hook (3) Montong bar (4) Side pillar bar (5) Bottom needle (6) Lower rail bar (7) Wheel assembly (8) Connect block (9) Fixing bar (10) Tension block (11) Connection button (12) Side pillar bar (13) Magnetic ( 14) It is composed of a wrinkle screen 15, and the body bar 4 holds the structure of the wrinkle screen 15 and is fixed with an anti-separation hook 3, and the upper rail bar 2, the lower rail bar 7 ), the wrinkle insect screen 15 is folded from the inside surrounded by the fixing bar 10 and the handle bar (1). The handle bar (1) is movable in both directions and is detachable with the fixed bar (10) and the magnet (14) thereon. The side pillar bar 13 is used to cover the complex structure of the internal fixing bar 10 and provide a clean environment.

Both ends of the fixing bar 10 are blocked with a base 6 , and the upper rail structure 2 , the lower rail structure 7 , and the fixing bar 10 are connected by a tension block 11 .

The body bar 4 supports the structure of the wrinkle insect screen 15 so that it does not get messed up, and the body bar 4 is connected to the escape prevention hook 3 and the handle bar 1 moves while the wrinkle insect screen 15 is formed. Even in a folding situation, it is possible to maintain the foldable wrinkle structure and honeycomb jug. The body bar 4 is installed in two or more so that even if the wrinkle screen 15 receives a force, the body bar 4 supports it to maintain the structure of the wrinkle screen 15 .

The base (6) and the anti-separation hook (3) are made of metal so that they can withstand strong force.

The wrinkle insect screen 15 is a room temperature curing type lacquered wrinkle insect screen, and is a foldable wrinkle insect screen or a screen of a folding honeycomb structure made of a non-woven fabric. The room temperature curing type lacquer may include refined lacquer, acrylic lacquer, urethane lacquer, and any one or more thereof. The room temperature curing type lacquer film has a thickness of 0.1 to 300 μm, but preferably 0.5 to 100 μm. The curing temperature of the room temperature curing type lacquer is 10-30oC, and the curing humidity is 20-70%, but more preferably 40-70%.

Fig. 2 shows a double-open-type structure with doors on both sides instead of the single-side-type structure with only one door in Fig. 1 . The double-open structure is a structure in which the single-open structure faces both sides and is suitable for making a larger size folding auxiliary door.
