Description

Method for manufacturing fireproof filling materials for fireproof walls of wood and steel insulation fire doors {Wood differential heat firedoor * fireproofWall a fireproof stuff materials manufacturing method}

The present invention relates to a fireproof filling material when manufacturing a fireproof wall for a wooden fireproof door and a steel fireproof door, and more particularly, to provide a method.

It is to provide a manufacturing method capable of simplifying the production method during manufacturing and enabling more accurate dimensional precision.

Currently, non-standard filling materials are used, so it is not possible to fill the inside accurately, so the fire resistance performance, insulation performance, sound insulation performance, etc. are deteriorated, resulting in defective products and many defects and defective products after construction. The cause of disputes with consumers has occurred, resulting in a lot of damage to each other.

Noise is constantly generated around our daily life today due to various factors such as the operation of various machinery and equipment and the operation of automobiles, railways, and sound equipment. Therefore, noise sources need to be designed to generate as little noise as possible, and when noise is unavoidably generated, it is necessary to block the noise from propagating to the outside as much as possible.

In addition, buildings require fire resistance and fire prevention performance to maintain performance for a certain period of time in case of fire and to evacuate and protect human life. In particular, it is difficult to rescue people in the event of a fire in group facilities, public facilities, nursing homes, and academies with many users or elderly people. On the other hand, indoor air quality management has increased compared to the past due to changes in lifestyle habits, and the air environment directly affects the human body in a closed indoor life, causing building syndrome, chemical hypersensitivity, and sick house syndrome. .

Currently, in order to secure the comfort of the indoor environment, regulations on the emission of pollutants from building materials are recommended. This product is made of 119p (patent registration) inorganic non-combustible raw material, which is a product of inorganic non-combustible raw material that does not emit toxic gases and VOC harmful to the human body as its main raw material.

To make a fireproof filling material, first, the filler is cut into the surface finishing material, fiberglass, as much as the usage standard, impregnated with inorganic nonflammable raw materials, dried, and then bonded to nonflammable mineral wool using a nonflammable adhesive (tested and certified product) produced by the company and dried. Afterwards, products are produced using wood insulation fire doors, steel insulation fire doors, and internal filling materials for fireproof walls.

As a soundproofing method, various soundproofing materials made of materials with sound-absorbing or sound-insulating performance are used to absorb noise and block its propagation path by installing soundproofing structures such as soundproof walls, soundproof partitions, soundproof rooms, and finishing materials for sound treatment. It is widely used. As a generally widely used soundproofing material, inorganic fiber materials such as general construction glass wool such as wood or concrete, and metal materials such as metal perforated pipes may be used singly or in combination.

Although there may be some differences depending on the place and purpose of use, soundproofing materials have excellent sound absorption and insulation in a wide range of frequencies, excellent mechanical properties (durability, etc.) and thermal properties (non-combustibility, flame retardancy, etc.), but are inexpensive to manufacture and easy to install. it would be preferable However, conventional soundproofing materials do not meet some of the above requirements (products with poor fire resistance, and glass wool or fiberglass performance is manufactured at 270 ° Fahrenheit and melted at 700 ° C, and mineral wool is 700 ° C fabricated and melted at 1,000 ° C) poses significant problems in their application.

The fire resistance filling test in Korea is tested at about 1,000 ℃ for 1 hour, but it is a fire resistance test that starts at 1,100 ℃ from the second hour, so 119P non-combustible raw materials (because it does not burn even at 1,500 ℃) are used to determine the lack of use of these products. It is to produce fireproof filling material by adhering to fiber glass or mineral wool.

Fire-resistant structure refers to a structure that allows a building to withstand a fire for a long time without significantly changing the shape or strength of the material to protect life and property, and to enable reuse of the building by simple repair after a fire. As the accreditation and management standards were legislated, the standards were further strengthened.

On the other hand, in general, when a building is newly built, a fire door formed to support the structure of a building and divide the interior is composed of a combination of heat and sound insulation, so that it can be used and applied to a building only after a difficult fire-resistance test is called.

30% by weight of 119P incombustible ammonium polyphosphate, 5% by weight of Guanidinesulfamate, 5% by weight of Ammonin hexametaphoshate, and 60% by weight of fiberglass and mineral wool Two sheets of non-combustible fiberglass are cut by impregnating with an incombustible composition composed of % of water, and inorganic incombustible adhesive is applied to both sides of the mineral wool between the first and second fiberglass surfaces, and then put in a regular happress to start the manufacturing line. The drying process of the adhesive material and the automatic cutting according to the standard and wrap packaging complete the product.

The present invention can be said to have the advantage of eliminating the defect of the product and reducing the occurrence of defects after construction by solving the problem of fire resistance performance as described above.

In order to achieve the above object of the present invention, the present invention provides a step of preparing a pair of first and second fiberglass impregnated with a non-combustible composition of plywood, bonding the pair of first and second non-combustible mineral wool, and Including the step of attaching, when manufacturing wooden heat insulation fire doors, steel heat insulation fire doors, and fireproof walls by inserting internal filling materials and covering both sides of the finishing material, fire resistance, sound insulation, and heat insulation are excellent.

The lightweight wall of the present invention can obtain the following advantages.

First, it has excellent sound insulation and heat insulation.

Second, fire resistance is excellent in durability and fire resistance is sufficient for 1 to 2 hours.

Third, by modularizing the product, the efficiency of production is good and defectivity can be improved.

Fourth, defects can be reduced when applied to buildings.

Fifth, quality is uniform due to factory production of materials.

Sixth, because the product is excellent, it is easy to export overseas.

Seventh, mass production and assembly process can be simplified by modularization.
