The present invention is characterized by the construction of a fireproof panel by coating a fire retardant mixed with a molding sand and a waterproofing agent so as to have a fire protection function on both sides of the foam formed by recycling and foaming the waste synthetic resin. Looking at it as follows.

1 is a perspective view to which one embodiment of the present invention is applied, FIG. 2 is a cross-sectional view of the present invention, and FIG.

In order to improve the understanding of the present invention, first, the regeneration process of the waste synthetic resin will be described first, and then the configuration of the present invention will be described in detail.

The waste synthetic resin is compressed by a compressor and dropped into the melting facility.

The drop distance is to ensure the distance of 1m in the air, which is put into the extruder installed under the evaporation of the gas humidifier, and the waste synthetic resin of the melt is removed through the discharge hole of the extruder cylinder, and the impurities are removed through an impurity exchange device. It is cooled by inflow into cooling water and produced into chips with 4 ~ 5mm particle size and put into recycled resin processing process.

The raw material produced by the chip is introduced into the extruder and foamed and extruded to obtain a foam (panel), and in this extrusion process, coated on both sides of the foam panel with a new raw material, and a reinforcing net (nylon, mono yarn, natsel net, etc.) inside the coating layer. ) Is manufactured by insert molding.

Forming, manufacturing process of the foam panel using such a waste synthetic resin is known.

The present invention is characterized by providing a fire protection function by forming a fire protection coating (2, 2 ') on the surface of the foam panel (1), it will be described below the configuration of the present invention.

Fire-resistant coating (2, 2 ') is formed by mixing the molding sand (Molding snad) and a water-proof (waterproof agent), the casting sand is mixed with the water-resistant using a dry sand (Dry Sand) of a particle size of 10 ~ 12Mesh.

In addition, as a waterproofing agent, fast forming ability and initial strength, such as New-crete (trade name), are maintained, and excellent durability against solvents for chemicals and solvents, and excellent heat resistance and the like are used.

The mixing ratio is mixed by molding sand (15 to 20%) and waterproofing agent (80 to 85%) as a weight ratio to form a fire retardant, and co-molded so as to be coated on both sides during extrusion molding of the foam panel 1.

That is, in the process of injecting, compounding, supplying, and extruding as in the normal extrusion process, the fireproofing agent is formed by coating and coating the surface of the foam panel 1 with a compounding (mixing) extruder (T dice) to form a fireproof panel. will be.

In the above, the surface of the foam panel 1 is formed of an embossed surface (3) embossed during extrusion molding, so that the fire retardant is more uniformly coated with a wider adhesive surface.

As described above, coating the fire retardant on both surface layers of the foam panel 1 in the extrusion process of the foam panel 1 allows the fire retardant to be fused and coated on the foam panel 1 by particle flow, and suitable drainage as uniform particles. It is intended to produce the coating thickness without any function and impurities.

When the coating thickness of the fire retardant is based on the thickness of the foam panel 1 as approximately 12 mm, the coating thickness of the fire retardant is preferably about 3 to 10 mm.

Hereinafter, with reference to the molding technology of the fire protection panel of the present invention will be described.

[Technology related to forming fireproof panel using waste synthetic resin]

One). Panel Forming

Extruder 130m / m

Extruder 90m / m

As a technical method of forming two sets (one table)

① Molding by extrusion can meet the diversification of material (resin) of product molding, and can be excellently molded into embossing.

② It can be installed by T-die by foam molding machine (extruder), and it can be formed up to 5 ~ 30m / m formed by transfer machine.

2). Panel Die and Recycled Material

Panel molding includes dies such as foamed embosses, and T dies are used.

In the diversification of the product, various dies need to be molded in various widths, and width adjustment plates are provided.

Good heat safety material (resin) has no problem in molding, but recycled material is used for foaming because it has a certain destruction of molecules, so it is excellent in weight (specific gravity) processability (sawing).

The temperature control of the die is particularly important because the multilayer die temperature extrudes other materials,

It is important not only to pay attention to the rigidity of the foam extrusion connected to the uniform extrusion in the width direction of the plywood (panel), but also to make the shape easy to disassemble and assemble.

3). Cooling Roll

The surface is finished after hard chromium plating and mirror finish is used to improve panel adhesion and smoothness.

The adjustment of the roll and temperature is to circulate the thermal intermediation inside the roll, and cold water and hot water can be used for the purpose (depending on the thickness)

In order to maintain the uniformity of the cooling rate during panel forming, it is necessary to have a temperature difference of 2 to 3 ° C on the left and right sides of the roll surface.

If the molding speed is high, the panel should be wound up to 3m / min enough to sufficiently cool the panel in the cooling roll, and the coated fire prevention (injection), etc., due to the lack of cooling ability.

On the other hand, the fire protection panel produced as described above is a predetermined standard unit {example; It is cut and formed into 150 (~ 1,000 (width) x 1,000-3,000 (length) x 5-50mm (thickness)), and it can be bonded and bonded to them and constructed.

For this purpose, as shown in the illustrated example, the concave portion 4 is formed on one side and the convex portion 5 corresponding to the concave portion 4 is formed on the opposite side such that the concave portion 4 and the protrusion 5 are mutually formed. Construction is achieved by joining together.

The above-mentioned concave portion 4 and the protrusion 5 may be implemented in various shapes with the exception of the illustrated.

The present invention configured as described above is excellent in impact strength and abrasion resistance, as well as to be used as a fireproof panel having a fire protection (간편한 火) function with easy construction.

The present invention is very simple and easy to carry out the construction work.

The construction is simply performed by bonding and jointing the concave portions 4 and the protrusions 5 adjacent to each other with a fireproof panel having a predetermined standard.

And, the fire protection coatings (2, 2 ') coated on both sides of the foam panel (1) is made of a waterproofing agent and molding sand with excellent heat resistance, the fire is made by heat resistance of up to 2,500 ℃.

The waterproofing agent serves as a so-called adhesive that is mixed with the foundry sand so that the foundry sand is sufficiently coated on the foam panel, but the waterproofing agent also has a high heat resistance and thus provides a fire protection function with the foundry sand.

As discussed above, the present invention not only provides advantages such as environmental pollution prevention and recycling of resources by recycling and using waste synthetic resins such as waste vinyl, but also provides fire protection panels with fire protection at relatively low cost in various buildings. It can be easily installed for the purpose of fire prevention,

This design is a fire protection panel made of waste synthetic resins, which is economical and has a very good practical value that can contribute widely to safety management of buildings.
