The present invention is the main raw material of a variety of high-temperature foamable minerals containing foamed pearl rock and foamed vermiculite particles as a partial component,

Non-combustible non-flammable plate material (or non-flammable material) prepared by using selected one of the inorganic adhesives such as sodium silicate (water glass), incomplete gel silicate silicate and sodium silicate cement as an adhesive, and the non-combustible plate based on the above As for the flooring material (or non-combustible cosmetic material),

More specifically,

It is made of vegetable fiber, including wood, to add a thermosetting resin adhesive,

It was derived for the purpose of replacing the use of fibrous board (FB), which is a general term for a wood panel which is mixed with other adhesive materials and hot pressed and cured.

The walls, ceilings and floors of public institutions, stations, offices,

Walls, ceilings and floors of trains, trains,

The walls and ceilings and floors of homes and businesses,

For interiors of all buildings and walls of large vehicles, including walls around kitchen counters in homes and businesses,

The present invention relates to a non-combustible plate member (or non-combustible cosmetic member) which replaces the use of a conventional fiber board, such as interior materials and furniture materials, and a non-combustible cosmetic plate member (or non-combustible cosmetic member) manufactured based on the above.

In addition, in order to simultaneously provide a design function that satisfies the design characteristics,

By adding an additional cutting process to the non-combustible substrate prepared according to the present invention,

The mixture formed by mixing the foamed particles and the adhesive is put into a mold of a specific shape and pressurized to produce a shape material molded into a desired shape.

On the other hand, in the conventional technology related to the present invention

Wood panel (fiber board) manufactured by dissolving in the form of vegetable fiber including wood, adding thermosetting resin adhesive, or mixing other adhesive materials, and thermally pressing and curing has been generally used.

The fiberboard is

By KS standard

(A) MDF (medium density fiberboard)

(B) Hard board (HB, hard fiber board)

(C) It is divided into soft fiber board (IB),

Depending on the density,

Medium density fiberboard is 0.35g / cm 3 ~ 0.85g / cm 3,

Soft fiber board is less than 0.35g / ㎡,

Hard fiber boards are classified on the basis of 0.85 g / cm 3 or more.

In addition, in the conventional technique for imparting flame retardancy to the base,

At the time of manufacture of the fiberboard mentioned above

1) by incorporating the process of impregnating or coating the surface of the wood or wood fiber raw material of the fiber board with a fiber flame retardant or non-flammable resin prepared by including a flame-retardant composition such as 10-2004-0028724 for the production of flame-retardant panels Technologies such as flame retardant composite plates have been disclosed,

2) A non-flammable metal thin plate and cement were further laminated on the surface of the fibrous plate to prepare a non-flammable layer-combusted flame retardant panel.

However, the above 1) is basically used for wood or wood fibers which are not flame retardant at all.

Since it was prepared through the method of further bonding the flame retardant substrate,

Partial flame retardancy by the non-flammable or flame-retardant resin as the additional component may be secured, but it is impossible to expect more effects,

2) is used as interior materials and furniture materials of public buildings that require fire resistance,

Although it is made of a panel that provides non-combustibility by processing metal materials such as aluminum and stone, etc. by laminating it to the surface,

In addition, in order to solve the above disadvantages, the woven fabric or nonwoven fabric of the inorganic fiber is impregnated with phenol resin, melamine resin, etc., which is a flame retardant resin,

Patent No. 10-0423023 manufactured by adhering the surface to a flame-retardant resin-treated paper is disclosed,

Although the above is a non-combustible inorganic fiber base material,

Since flame retardant resins are used as binders, this also has a disadvantage that it cannot escape the scope of the conventional flame retardant substrate.

Therefore, the present invention provides a non-flammable base material that improves the flame retardant properties provided by the above-described known techniques to non-flammable properties, and thus, completely non-flammable, which can satisfy various effects such as manufacturing cost reduction, light weight, heat insulation, sound insulation, design, and the like.

The above is described in more detail as follows.

1) A process for producing expanded particles by pulverizing and firing the various high-temperature foamable minerals alone or in combination

To provide lightness and incombustibility to various thermally expandable minerals, including vermiculite, perlite, garnet, hornblende, olivine, mica, feldspar, pyrite, ocher, diatomaceous earth, white clay, etc.

The particles are used alone or in combination, and pulverized and calcined to produce lightweight inorganic foamed particles.

Thermally expandable inorganic minerals are generally

It is known to reduce foaming at temperatures around 800 ~ 1400 degrees.

In addition, the minerals heat-foamed at the above temperature is provided with pores therein, thereby providing high weight, heat insulation, and sound insulation.

Therefore, preferably through the present process, the specific gravity is 0.1 or less, and constitutes foam particles having a diameter of about 1 to 3 mm, and uses the foam particles as the main raw material of the present invention to prepare plate and shape members.

However, the specific gravity and particle size are not limited to the above.

According to the strength and durability of the product to be manufactured can be modified by manufacturing.

2) A step of spraying or mixing selected foams among the sodium silicate (water glass), incomplete gel silicate, and sodium silicate cement which are adhesives of inorganic raw materials to the foamed particles.

The sodium silicate (water glass) is a representative nonflammable inorganic adhesive widely used in various industrial fields.

In addition, the sodium silicate (water glass) or

The incomplete gel silicate prepared by gelling by introducing a kind of material selected from various acids (strongly basic) or amphoteric oxide into the sodium silicate can be used as a binder.

In addition, by mixing the sodium silicate and galvanization in an appropriate amount ratio, and heating and curing at a temperature of about 90 to 300 degrees Celsius, the sodium silicate cement is improved to improve the weak water resistance of sodium silicate.

On the other hand, the mixing ratio of sodium silicate and zincification in the above is as in the patent application 10-2004-0091651 and 10-2004-0091653,

It is preferably prepared by mixing 40 g of a 40% solution of polysilicon silicate with a ratio of 40 to 60 g of zinc powder,

The incomplete gelated silicate is also used in silica gelation of boric acid (in the production of silica gel) for the slow gelation reaction, as in the following self-invented patent applications 10-2004-0091651 and 10-2004-0091653. It is preferable to use it in an amount less than the proper amount of).

However, not limited to the boric acid,

Other gelling reactants that can cause gelation reactions in sodium silicate can be introduced in slower gelation reactions by introducing them in an amount less than that which would result in complete gelation as described above.

This is done to encourage rapid dehydration of the water contained in the sodium silicate (water glass).

On the other hand, the selected one of the above-mentioned sodium silicate or incomplete gel silicate silicate or sodium silicate cement is applied by spraying on the surface of the foamed particles and mixed stirring and foamed particles produced through the process of 1).

As the coating method

In general, a method of mixing and stirring the inorganic foam particles and the adhesive may be used.

But,

The pulverized particles of the 1) process is foamed through a high temperature of 800 ~ 1400 degrees in the foaming apparatus,

Even after the foaming of the particles, the remaining particles (maintained more than 500 degrees Celsius) remain in the foamed particles,

Rapidly forcing the foam particles into the adhesive spraying device connected to the foaming device so that the residual heat is not cooled,

By spray coating an inorganic adhesive on the foamed particles in the heated state,

Inorganic adhesive is heated by the residual heat of the foam particles, it can be more preferably produced through the preferred manufacturing method according to the invention to allow the moisture in the adhesive can be quickly dehydrated by the heating,

This is a very preferred method to prevent the additional burden such as equipment and time required for the additional heating step or additional drying step for dehydration of water in the sodium silicate.

However, unlike the above, in the manufacturing process according to the present invention

a) heat drying process of plate or shape member,

b) or an additional step of preheating the adhesive, which is preferably produced by

The a) is to remove the moisture remaining in the adhesive that is a component of the plate member and the shape member manufactured through the molding process, to dehydrate by heating and drying the plate member and the member at a temperature of about 120 ~ 1400 degrees Process,

In step b), before the mixing and stirring process, the adhesive is preheated to a temperature of 120 ° C. or higher in the preheater, thereby partially dehydrating the moisture contained in the adhesive, followed by mixing and stirring with the foamed particles, thereby providing faster drying. It is a process to achieve this.

(※ Sodium silicate causes dehydration by adding boric acid, sulfuric acid, hydrochloric acid, alcohol, etc., which leads to precipitation of silicic acid, which is the result of aggregation of SiO2 tetrahedron when H2O in sodium silicate as dehydrated water.

In addition, sodium silicate

By heating at 120 ~ 500'C, 95% dehydration progresses and porousization occurs.

And, the inorganic foam particles coated with the adhesive through the

Since the unit weight is reduced to 50% or less compared to the inorganic foam particles coated with the adhesive through mixing and stirring, which is a general coating method, the weight of the product according to the present invention can be reduced to 50% or less to provide excellent lightness. It is a very desirable manufacturing method that can be.

The reason why the weight of the inorganic foam particles coated with the adhesive through the mixing and stirring is high is due to the reason that the adhesive penetrates into the pores of the foam particles during the mixing and fills the pores.
