JP2001271568A - Flame-retardant wooden fittings and method for producing the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a safer living environment at a low cost by applying a harmless flame retardant to wooden fittings, and imparting fire resistance efficiency to the wooden fittings per se. SOLUTION: A wooden paper sliding door is produced in a very ordinary manner, and a siliceous flame retardant is applied to the door and dried. Thereafter, flame-retardant sliding-screen paper which is commercially available is stuck to the door, and the resultant paper sliding door is installed in a wooden frame which has been subjected to flame-retardant treatment in the same manner, such that the door can slide rightward and leftward. In the same manner as in the paper sliding door, a wooden frame door is produced in an ordinary manner, and it is subjected to flame-retardant treatment by using an inorganic salt flame retardant and then sufficiently dried. Thereafter, the door is clear-painted, and then installed in a wooden frame which has been subjected to flame-retardant treatment, such that the door can be forward opened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is a fire prevention measure that reduces damage caused by fire spread in a fire by applying flame retardant processing to a wooden fitting used in a building and makes initial digestion effective.

[0002]

2. Description of the Related Art Conventionally, wooden materials can hardly be used in designated areas for fire protection or places where the use of flame-resistant products is required, and non-combustible materials such as aluminum or non-combustible materials that require special technology Fittings made of wood were used. Even if natural wood is used, if it is installed with an aluminum sash facing the outer wall, the cost of building will tend to increase because of the need to keep the distance from the window by using a bay window structure, etc. There is also a method in which construction is carried out after the on-site inspection.

[0003]

While natural wood is being reviewed in a house-sick and aging society, it is possible to live in places regulated by the Fire Service Law by applying flame-retardant treatment to flammable wooden fittings. Enable the use of warm wood without disturbing the environment, and make life safe and secure.

[0004]

Means for Solving the Problems A fire flame is produced by sufficiently applying a colorless, odorless and harmless flame-retardant paint made of inorganic salts or silicic acid to wooden fittings and giving the wooden fittings themselves, which are combustible materials, flame retardancy. Even if it hangs, even in a high temperature atmosphere due to a nearby fire,
It only carbonizes without igniting, burning and burning. Therefore, not only can the fire spread in the event of a fire be suppressed, but it can also be attached to the glass sash window, and the Japanese-style room, which is a feature of Japanese architecture, can be constructed safely.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Inorganic salts or silicic acid-based flame retardants are sprayed or immersed in wooden fittings that have been conventionally made using natural wood, so that they are infiltrated and thoroughly dried. This eliminated a number of problems with burning wooden fittings during a fire.

[0006]

[Examples] There are various types of wooden fittings such as frame doors, paper pasted shoji, glass shoji, lattice doors, sliding doors, gates, gates, rain doors, screen doors, Shoin, ranma, etc. To explain the pasting shoji, first, a wooden shoji is manufactured in a very ordinary manner, a silicate-based flame retardant is applied and dried, and then a commercially available flame retardant shoji paper is pasted. It was attached to a wooden frame so that it could slide left and right. Next, the wooden frame door is manufactured by the same general manufacturing method, flame-retardant using a flame retardant of inorganic salts, dried sufficiently, and then subjected to clear coating. The frame was mounted so that it could be opened and closed forward.

[0007]

As the surface is carbonized and oxygen is supplied, the larger the tree, the more difficult it is to burn. As a result, a relatively small piece of wood was burned. Although it was carbonized, it did not spread to other parts at all. In addition, only the portion of the shoji paper that was exposed to the flame was carbonized black and a hole was formed, but it did not spread.

Claims (3)

[Claims] 1. Infiltrating natural wood with a silicate-based flame retardant,
Wooden fittings that meet the criteria for flame retardant performance in a flameproof test. 2. A wooden fitting which saturates natural wood with a flame retardant of an inorganic salt and satisfies the standard of flame retardancy in a flameproof test. 3. A wooden fitting which is made of natural wood and impregnated with a colorless, odorless and harmless flame retardant, and which satisfies flame retardancy standards in a flameproof test.
