2. Publication

a) U.S. Patent No. 3,098,062 mentions a lining form having multiple layers, which consists of metal fibers and a flexible inner element made of gypsum of at least one surface layer. The fibrous element is applied with a paper layer which serves as an excellent surface for the final covering layer (coloured).

The strength of gypsum in the flame is limited, and its surface layer is soft and brittle.

b) Belgian patent application 886,016 mentions a method for producing a heat-insulated cast layer consisting of magnesium oxide and magnesium chloride, the mixture of which may be mixed with various kinds of reinforcing materials.

In the application of the reinforcing material, specific examples such as methods of applying soundproofing and fire resistance as well as various structural strengths, application ranges, and verification methods are not mentioned.

c) Patent application WO 97/21884 mentions a lining panel consisting of one or two insulating layers.

Fire resistant binders:

Magnesium chloride

Magnesium Sulfate

-Magnesium oxide

Contains sodium silicate.

The basic component of the refractory material is at least 47% or more magnesium chloride, and the basic component of the refractory material applied to the lining panel is 48.3% or more magnesium oxide.

The use of magnesium sulphate has many problems when the panel is in high relative humidity and low temperature conditions in the manufacture, transportation and installation of the panel in ships.

The internal reinforcement of the lining panel is constituted by the same binder, which in turn delivers noise and results in failure to meet strict soundproofing regulations.

In addition, the publication is referred to as only one floor and wall combined without a detailed description, so it is not possible to determine whether it is a complete system with fire resistance, i.e. whether it is a complete assembly with linings, dividing walls, ceilings and doors. Can't.

Weight-reducing materials used for ship accommodation are becoming increasingly important for weight reduction (which can increase the capacity of ships) and to meet stringent regulations on current passenger ships.

Today, in the national industrial sector in a competitive environment, the use of accommodation on prefabricated ships continues to increase to reduce the time spent on shipbuilding.

Therefore, it is essential to meet the strict fire protection rules of the SOLAS (Safety Of Life At Sea) Convention, as well as the strict sound insulation design for the comfort of travelers and crew.

3. Purpose of invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a fireproof insulation panel which is composed of a complex structure so as to be properly connected to each other, to have strict soundproofing properties, high rigidity for maximum tensile strength, and low weight.

4. Achieve the object of the invention

The object of the present invention is achieved by the interior structure of layers and panels in which connection and pre-assembly are performed as well as the transportation and installation of the final structure used for accommodation such as side linings, partition walls, ceilings, doors, living rooms and toilets. .

5. Internal structure of layers and panels

The internal structure of the layer and the panel is achieved by providing one or more mineral fibers as a composite layer of multiple layers of glass fibers as a support, an insulating material and a binder containing magnesium oxide, magnesium chloride and sodium silicate in suitable proportions, Therefore, after solidification, the set intensity for the flame is maintained.

1 shows a composite layer of a unitary panel according to the invention.

The first layer is made of low density glass fibers so that the surface of the panel is smoothed after taking out of the mold together with solidification.

The second and third layers are made of high density glass fibers.

The fourth layer is composed of mineral fibers.

Pieces of mineral fiber are suitable for panels of small volume.

At certain distances, in order to improve compressive strength and to meet stringent acoustic insulation designs, high density pieces of binder-filled mineral fiber are attached parallel to and perpendicular to the bulky panel.

The fifth and sixth layers consist of glass fibers similar to the second and third layers.

The above-mentioned layers are combined with a binder of a composite layer to constitute a system of excellent fire resistance and sound insulation and low weight.

6. Synthesis of Binder

Magnesium mixtures mixed with magnesium oxide-magnesium chloride (MgO-MgCl ₂ ) improved by sodium silicate additives are used as binders in the panel.

For the preparation of the binder, the following natural materials are used.

1, magnesium (MgO) with a purity of 91-95%,

2, magnesium chloride (MgCl ₂ ) of 47% purity,

3, sodium silicate (SiO ₂ : Na ₂ O)

4, water

The binder mixture during application is as follows.

1, magnesium (MgO) 33.33%

2, magnesium chloride (MgCl ₂ ) 24.24%

3, water glass 2.02%

4, water 40.40%

As seen in the mixture, the magnesium oxide is the basic component of the mixture with good fire resistance.

While water glass acts as a binding means, magnesium chloride increases the strength of the mixture after solidification and improves fire resistance.

Magnesium used is derived from burning the magnesite of Evoias or Vavdou Halkidikis.

The binders described above are particularly suitable for panels made by cold compression techniques.
