Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown, the flooring material for laying using cork of the present invention is composed of cork as a main component, and is configured to coat the surface of the cork with a flame retardant to minimize damage caused by fire by blocking the spread of flame in the event of a fire. , The upper laying cork layer 100 laid on the upper part of the ground, the lower laying cork layer 200 laid on the upper surface of the upper laying cork layer 100 and forming the surface layer of the flooring material for laying, and the upper laying cork It is composed of a coupling member 300 that improves the bonding force with the ground during laying of the layer 100 and prevents cracking of the upper laying cork layer 100.

The upper laying cork layer 100 is laid on the upper part of the ground, a cork mixture to which cypress in powder form is attached to the surface of cork ground to a certain size, a water-soluble acrylic binder, or a water-soluble urethane binder. And, a flame retardant mixture including high-purity silica, alumina, carbon, and zirconia is configured to be mixed at a certain weight ratio, and is configured to be laid by a certain thickness on top of the lower laying cork layer 200.

As shown in FIG. 3, the upper laying cork layer 100 can be manufactured by sequentially performing the cork mixture manufacturing step (S20), the cork mixture coating step (S22), and the flame retardant cork mixture manufacturing step (S24). will be.

The cork mixture manufacturing step (S20) is a step of attaching cypress wood in powder form to the surface of cork pulverized to a certain size to prepare a cork mixture with the cypress wood attached, with a cork 65 in the total weight of the cork mixture. It is configured to be mixed by stirring in a ratio of weight% to 80% by weight, cypress 10% to 20% by weight, and cork binder 10% to 15% by weight.

At this time, the cork is composed of a particle size of 1.5mm ~ 6.0mm, and the particle size of the cypress tree is preferably composed of 0.5mm ~ 2.0mm, but the entire area of the floor or the environment of the construction site where the eco-friendly flooring material is constructed. Of course, it can be applied differently depending on.

Here, if the particle size of the cypress tree is less than 0.5 mm, when the cypress trees are attached to the surface of the cork, the cypress trees agglomerate with each other so that they cannot be uniformly attached to the surface of the cork, which eventually results in the cork mixture A problem of forming a non-uniform size may occur.

In addition, when the cypress wood having a particle size exceeding 2.0 mm is bonded to the surface of the cork by a cork binder, excessive gaps between the cork mixtures are formed during the coating step (S22) of the cork mixture to be described later. This reduces the strength of the flooring material, and after a certain period of time, the cypress tree is separated from the cork by an external impact, thereby shortening the life span of the flooring material.

In the cork mixture coating step (S22), the cork mixture prepared in step S20 and the cork binder are further mixed so that a coating film of a certain thickness is formed on the surface of the cork mixture in a state where the cypress is attached through the cork binder, At the same time, it is a step to achieve adhesion between the cork mixtures.

The cork mixture coating step (S22) is configured to mix by stirring in a ratio of 70% to 85% by weight of the cork mixture and 15% to 30% by weight of the cork binder.

The flame retardant cork mixture preparation step (S24) is performed after the above-described cork mixture coating step (S22) is completed, and the flame retardant mixture is further added to the coated cork mixture to perform secondary stirring, thereby making the cork mixture This is a step for minimizing damage caused by fire by forming a flame retardant layer by the flame retardant mixture on the surface of the coating film to prevent flames from spreading through the cork mixture even if a fire occurs in the flooring material of the present invention.

In the flame retardant cork mixture manufacturing step (S24), mixing by stirring is performed at a ratio of 85% to 90% by weight of the cork mixture having a coating film and 10% to 15% by weight of the flame retardant mixture.

Here, the flame retardant mixture may be configured such that high purity silica, alumina, carbon and zirconia are mixed in a certain weight ratio, and in the present invention, in the total weight, 50% to 70% by weight of silica and 20% to 30% by weight of alumina , It may be made of a mixture mixed in a ratio of 5% to 10% by weight of zirconia and 5% to 10% by weight of carbon.

That is, the flooring material for coating and laying of the present invention may be a cork mixture coated with a flame retardant mixture on the surface, and the floor to be constructed is a children's play facility or is configured to be constructed on a wall surface. At this time, in the case of children's play facilities, construction may be performed not only outdoors but also indoor play facilities.

The upper laying cork layer 100 of the present invention configured as described above is formed by laying to a certain thickness after the construction of the lower laying cork layer 200 is completed, and performing a flattening operation while compressing it through a press, etc. The components constituting the laying cork layer 200 are formed while being adhered to the lower laying cork layer 200 by a cork binder.

The lower laying cork layer 200 may be made of any one of germanium, jade, ocher powder, or two or more additives mixed with cork.

For example, the lower laying cork layer 200 of the present invention is composed of a mixture mixed in a ratio of 75% to 85% by weight of cork, 10% to 15% by weight of cork binder, and 5% to 10% by weight of additive components. It can be.

Here, the additive components are mixed with 75% to 85% by weight of the ocher powder, 10% to 15% by weight of germanium, and 5% to 10% by weight of jade, based on 100% by weight, and mixed with the cork and cork binder. It can be configured to do this.

In addition, when the additive component is mixed with cork, it is configured to be mixed in a pulverized state to a certain size, and in the present invention, it is configured to have a uniform particle diameter of 0.5 mm to 1.0 mm.

This is because, when the additive component is formed larger than 1.0 mm, when mixing with cork and bonding by a cork binder, an excessive gap is formed between the cork and the additive component to lower the strength after a certain period of time. can shorten the lifespan of the flooring material while being separated from the cork by external impact, etc., and when formed smaller than 0.5 mm, a gap is not formed between the cork and the additive component, so the strength can be improved, but the water permeability is reduced. In the present invention, the additive component is configured to have a uniform particle diameter of 0.5 mm to 1.0 mm so as to secure constant water permeability and strength.

The lower laying cork layer 200 of the present invention configured as described above is formed by laying to a certain thickness in a state where the coupling member 300 is installed on the ground 10, and compressing it through a press, etc. ) The components constituting the cork binder are formed while being bonded to the coupling member 300 and the ground 10.
