It is the invention of the content to solve the disadvantages of the above.

In order to achieve the above problem,

The present invention provides a ceramic foamable material prepared by using incomplete gel silicate silicate having a hollow formed therein as a binder.

Hereinafter, the configuration of the invention will be described in detail.

Generally, ceramic foam moldings prepared using incomplete gel silicate as a binder,

Incomplete gel silicate, which is an incomplete gel-like (colloidal) material prepared by adding an acid, an amphoteric oxide, or an amphoteric hydroxide to sodium silicate, is used as a binder.

It is mixed with foamed ceramic particles to prepare a ceramic foamed molding by heating, foaming, drying, curing and cutting.

However, in the present invention

The foamed molded article is made of a lighter weight lightweight molded foam,

In order to increase insulation, sound insulation and sound absorption, a hollow part is formed in the foamed product.

In order to achieve the above object,

Raw materials (foamed particles + incomplete gel silicate) supplied from the hopper (mixing and feeding) of the extruder are introduced into the extruder,

Raw material passed through the extruder is injected into the molding machine, the hollow portion is stamped , extruded

The extruded, molded foam is supplied to the top of the moving conveyor,

The foamed product is dried and cured through a drying apparatus installed in the conveyor,

The dried and cured foamed molded product is drawn out through a drawer operated at an appropriate speed,

The process of obtaining the finished foamed molding by cutting the drawn foamed molding to a desired length through a cutter constitutes a basic element of the manufacturing process according to the present invention.

Then, the manufacturing method according to the present invention will be described in more detail.

The hopper (mixing and supplying) is provided with a raw material discharge amount control device to properly control the supply amount of the raw material,

The raw material supplied from the hopper is forwarded while being kneaded, heated, foamed, and compressed by a screw and a cylinder, which are extrusion devices.

The inside of the cylinder is heated by the thermostat heating device configured to heat the inside of the cylinder,

As a result, the raw incomplete gel silicate is thermally foamed inside the cylinder,

By extruding and supplying the foaming material which is foamed and extruded in the cylinder which is the said extrusion apparatus to the molding machine installed in front,

As the foamed material slowly passes through the hole (cross section) of the molding machine,

The foamed molding with the desired shape is continuously drawn to the top of the mobile conveyor connected to the front of the molding machine.

But for more homogeneous foaming of the foaming material,

In the forming step, the secondary heating device is installed in the molding machine so as to heat the molding machine,

By foaming the raw material that has not been completely foamed in the cylinder in the molding machine, the foamed product is prepared by inducing homogeneous foaming of the raw material.

In the next step, for the rapid drying of the prepared foam molding,

When the foamed molding is extruded from the molding machine and continuously connected to the upper end of the conveyor,

Quickly dry and cure through hot air and microwave irradiation device, which is a drying device installed on the top of the conveyor,

The dried and cured foamed product is taken out using a drawer,

The drawn foamed molded product is cut to a desired length using a cutter to prepare a ceramic foamed molded product prepared by using the finished incomplete gel silicate silica as a binder.

In addition, in order to manufacture the foam molding in individual units,

The raw material is injected into the inside of the molding machine where the hollow part is imprinted ,

The above is pressed, heated, and foamed by a press with an upper mold.

The prepared foamed product is taken out from the molding machine,

To prepare a foamed molded product by drying and curing using a drying device (heating, hot air, microwave irradiation, at least one drying method in parallel) made in a stand-alone type, or

The foamed product drawn out from the molding machine is discharged to the upper end of the movable conveyor, and dried and cured while gradually moving through a drying apparatus (composed at least one drying method among heating, hot air, and microwave irradiation) installed at the upper end of the conveyor. To produce a completed foam molding.

Through the above-described example, the case of the foamed molding manufactured using only ceramic foam particles and incomplete gel silicate as a raw material has been described as an example.

Through a uniform manufacturing method, in order to enhance the performance and durability of the foamed molding, a mixture of various organic and inorganic components, including steel fiber, fiber breaking water, paper breaking water, cotton, glass wool, etc. In addition, ceramic foam moldings prepared by mixing may also be prepared by forming hollow parts according to the present invention.

In particular, in the case of

Due to the weight of the mixed raw materials (steel fiber, fiber chain sulphate, etc.) mixed in the main raw material, the weight of the foamed molded article is significantly higher,

By forming and manufacturing the hollow part according to the present invention, it is possible to produce a ceramic foam molding with improved performance while avoiding excessive weight increase.

In addition, the hollow portion according to the present invention may be manufactured in various forms, by applying a hollow portion having a desired shape in a hollow portion of a single layer, a hollow portion of a double layer structure, a cylindrical structure, an elliptical structure, a square pillar structure and the like. (FIG. 1).

Coating a coating material of various inorganic materials on the surface of the foamed molded article produced in the above various methods and forms,

By affixing a finish including paper, fabric, synthetic resin film, fiber powder locking, etc. to the surface, the aesthetic function and functionality are enhanced, thereby providing a highly usable foamed molded article with an extended use range.

together,

In addition to the above-described manufacturing method, various manufacturing methods are already known.

Therefore, even in the case of ceramic foam moldings prepared by using incomplete gel silicate silicate prepared through a known production method other than the illustrated production method as a binder,

Of course, it can be manufactured by configuring the hollow part according to the present invention,

It should be considered to be included in the claims of the present invention.

The ceramic foamed molding prepared by using incomplete gel silicate silicate having a hollow portion formed therein according to the present invention as a binder is an environmentally friendly ultra-light foam molding.

Increase in distribution cost due to excessive weight exceeding the required properties of existing foamed moldings,

Rise in manufacturing cost,

The increase of excessive labor required by heavy weight and deterioration of workability such as cutting property, transportability,

It solves the shortcomings of building exterior wall, avoidance of internal wall material construction, etc. due to low thermal insulation, air intake, and sound insulation.

The weight is significantly reduced compared to the foamed molding without the hollow part,

This reduces the distribution cost,

Reducing raw material requirements,

Manpower saving, air saving,

Ultralight weight of products,

Increased insulation,

The thermal bridge phenomenon is reduced, eliminating condensation due to the crossover which makes the inner wall wet.

Since the heat loss to the outside can be reduced to a minimum, it is possible to reduce the fuel cost for cooling and heating the building.

In addition, the noise transmitted from both the inside and the outside is absorbed by the hollow part, thereby blocking the transmission of noise.

Sound insulation and sound absorption are effective,

Its practicality is improved by coating and bonding materials of organic and inorganic materials that have various functional and aesthetic functions to the outside.

Electric wires and pipes can be drawn in the hollow part, and the appearance is maintained.
