Description

Flame retardant eco-friendly hybrid door {Door for protecting fire accident}

The present invention relates to a flame retardant eco-friendly hybrid door, and more specifically, by using a flame retardant function of the door and a non-toxic eco-friendly material, emission of toxic gases is minimized in the event of a fire and at the same time, the flame propagation time is delayed to minimize damage from flame and heat. Evacuation time can be obtained, and in particular, it relates to an optimized flame retardant eco-friendly hybrid door that is resistant to moisture and does not warp.

Doors made of processed wood such as hardwood or plywood, which have been widely used from the past, are heavy, vulnerable to moisture, and have a short lifespan. For this reason, as the supply of wood is gradually limited, there are door problems such as increased manufacturing costs. In order to supplement and solve the problems of wood substitutes and wood doors, various types of synthetic resin doors have been developed, produced, and sold. there is.

The synthetic resin door of the general structure of the existing synthetic resin door is PVC or ABS.

A square mold formed by extruding synthetic resin such as a back and serving as a frame supporting the door, a reinforcing wood disposed inside the square mold, and a front surface formed by molding synthetic resin into a plate shape and disposed in front and rear of the square mold It is composed of a plate and a back plate, and a filling material between the front plate and the back plate, that is, filled in the inner space of the door to reinforce strength. As the filler, synthetic resin is foamed and filled or honeycomb-shaped paper reinforcing material is filled. The foamed and filled method is excellent in terms of soundproofing, dustproofing and strength reinforcement, but the foaming and filling operation is complicated. However, since the door has the disadvantage of heavy weight and high cost, light weight, work convenience, cost, etc.

Considering this, paper honeycomb is used as a filler in many cases. The square mold is manufactured in the form of a synthetic resin bar, and the inside is made by laminating plate-shaped trees in multiple stages.

Reinforced by reinforcing wood formed of laminated wood to form a double-structured square reinforcement frame, to provide a sturdy door frame.

The front plate and the back plate may be made of a synthetic resin plate, but are generally formed by attaching a finishing material such as a PVC film or veneer to the surface of a processed plywood such as a medium density fiber board (MDF).

In addition, while allowing people to pass through the door at normal times, it is being strengthened under the Building Act to delay the penetration time of the flame in the closed state in the event of a fire and to minimize the generation of toxic gas.

Door technology is known from Korean Patent Nos. 10-1832383 and 10-1912780. In addition, among the doors that are widely used in general interiors, resin doors generate toxic gas in the event of a fire, and in the event of death due to fire, there is a problem in that casualties are first caused by toxic gas poisoning.

In addition, although the patterns and colors of the door are diversifying, it is difficult to upgrade due to the problem of looking too light, and there is a problem that the cost for upgrading is increased with the simple existing door method.

The present invention was developed to solve the conventional door problem, and its purpose is to be manufactured using a light and inexpensive product to protect it from flame and toxic gas in case of fire, and in particular to give time to evacuate To develop an eco-friendly flame retardant resin door.

Another object of the present invention is to provide a flame retardant eco-friendly hybrid door in which the material used for the door is formed to have flame retardancy and non-toxicity.

The solution of the present invention is a door formed of a main panel, which is a front panel member and a rear panel member, and a honeycomb structure and a square main frame in the inner space between the main panel,

When the main panel is attached with a PP layer and a PP decorative sheet layer, an eco-friendly adhesive consisting of 14 to 20% by weight of any one selected from methyl carbonate and dichloromethane and 80 to 86% by weight of polyurethane resin is attached and combined. did

When the flame retardant eco-friendly hybrid door of the present invention is attached to the front and back of the main frame with an MDF layer, a PP layer, an aluminum layer, or a PP decorative sheet layer, 14 to 20% by weight of any one selected from methyl carbonate and dichloromethane and polyurethane resin This was achieved using an eco-friendly adhesive consisting of 80 to 86% by weight.

The present invention develops door products that can be installed in areas where installation of flame retardant doors is not compulsory, and can be manufactured using light and inexpensive products to protect from flames and toxic gases in case of fire, and are widely used around the world to prevent fire There is a great effect that can greatly reduce human casualties from

As described above, not only the material of the door is environmentally friendly, but also the adhesive is also characterized by being environmentally friendly, which is a material that does not generate toxic gas in case of fire.

As described above, it is a very useful invention that minimizes the generation of toxic gases in the event of a fire by using an eco-friendly adhesive such as a layer or frame adhered to a door.

The present invention shown in FIG. 9 has a feature formed to secure time to evacuate by blocking toxic gas and heat permeating between the door and the door frame as much as possible.

In another embodiment of the present invention shown in FIG. 8, the configuration of the present invention can be said to be a configuration in which flame and smoke do not pass through by blocking the gap between the door and the door frame. However, this structure prevents smoke from escaping through small gaps, although it is difficult to completely block it, so that it reaches a high temperature in case of fire. It was formed by inserting a refractory filler (56) between (30). As the inserted fireproof filler 56 expands in the event of a fire, it pushes the foam core layer 30 to adhere between the door and the door frame. It has a feature that allows it to be filled and tightly adhered. In particular, a plurality of heat transfer protrusions 55 are formed to protrude from the aluminum layer 60 in contact with the refractory filler 56 so as to conduct heat transfer.

In particular, there are many gaps between the door and the door frame, which is a very useful invention that solves the problem of being vulnerable from toxic gas in case of fire.
