Description

Elastic flooring material using foamed olefin and its construction method {Elastic mat material and its method of manufacturing}

The present invention relates to an elastic flooring material using a foamed olefin and a construction method thereof, and more particularly, to a configuration of a floor sheet or a mat body for various uses and to provide a method for constructing an elastic floor using the same.

Elastic sheets are widely used for various purposes.

Sheets of elastic material are widely used, for example, in multiple aggregate areas such as children's playgrounds and apartments, central plazas, walkways, sports facilities, and various leisure industries.

Conventionally, in order to construct an area having such elasticity on the floor, concrete floors are formed uniformly, and 1.5 to 5.2 mm waste rubber sheets are laid thereon for waterproofing.

The urethane chip, waste tire grinding rubber, ethylene propylene rubber (EPDM) chip, etc. were stirred on a waste rubber sheet by using an adhesive, and then flattened as a weight and dried.

Alternatively, in the manufacturing plant, the waste rubber pulverized powder was mixed with the adhesive to prepare a mat having a predetermined area in the molding machine, and the mat was assembled on-site and vaccinated.

When the elastic material construction method according to the prior art as described above, in particular when the waste rubber sheet is laid on the floor or the elastic mat of the waste rubber crushed, etc., a large amount of heavy metals contained in the waste rubber is eluted by excellent or the like, It is scattered, especially in the summer, the rubber smell is badly induced, there was a very unsanitary side.

In particular, in recent years, the awareness of the environment is being raised, and the construction environment, such as children's playgrounds, such as the need to obtain the KC mark, which is a national certificate, has arisen.

Therefore, the elastic flooring material and the construction method using the foamed olefin of the present invention avoid the conventional elastic flooring material and construction method using harmful materials such as waste rubber sheet or waste tire crushed products and minimize the elution of heavy metals, such as rubber odor There is no induction to enable eco-friendly construction,

In particular, by using a polyolefin resin material that is a recycled resource, it provides an elastic sheet or a mat and a method of constructing the same that can be usefully used in bicycle roads, elastic walkways, indoor and outdoor children's playgrounds, multi-assembly facilities, gymnasiums, and the like.

Therefore, the present invention is invented to solve the above problems,

In constructing the elastic flooring material to be provided on the concrete foundation surface to give an elastic floor surface;

The elastic material constituting the elastic flooring material is manufactured by heating a sheet of foamed olefin or foamed olefin into a mold after grinding, heating and pressing, and then assembling and constructing the mat on the mat. The elastic flooring is characterized by finishing with a polyurethane resin, a urethane waterproofing solution, and a sunscreen, an antioxidant and a UV coating agent represented by acrylic resin on the construction surface.

In addition, as a specific construction method,

In construction of the elastic flooring material to be applied on the concrete foundation surface to give an elastic floor surface;

As the elastic material constituting the elastic flooring material, a sheet body or expanded olefin of foamed olefin is put into a mold after pulverization and manufactured by heating and pressing, and then based on any one of mats cut to a constant size.

Preparing the foamed olefin sheet or mat, pressing the foamed olefin sheet or mat on the concrete floor which is placed on the bottom surface of the construction object, and then pressing the adhesive to firmly adhere to the bottom surface; After the mat is mixed with a polyurethane resin or a urethane waterproofing solution on the construction surface, the surface is repeatedly applied to planarize the surface, and the surface is finished with a sunscreen, an antioxidant, or a UV coating agent represented by acrylic resin. Comprising;

As another possible construction method,

Preparing the foamed olefin sheet or mat, pressing the foamed olefin sheet or mat on a concrete floor which is placed on the bottom surface of a construction object, and pressing the adhesive to firmly adhere to the bottom surface, the foamed olefin Applying or mixing 5 to 10% of the total chip weight with one or more chips selected from EDPM chips, foamed olefin chips, urethane rubber chips, and foamed EVA chips on the surface of the sheet or mat, and required elasticity Optionally performing roller pressurization and drying according to the drawings, and finishing treatment with a sunscreen, an antioxidant, or a UV coating agent typified by urethane waterproofing or acrylic resin on the dry construction surface again. .

The elastic flooring material using the foamed olefin of the present invention and its construction method have usefulness such as dissolution of heavy metals, induction of heavy metal dust and recycling of resources.

Hereinafter, the elastic flooring material and the construction method using the expanded olefin of the present invention for achieving the above object with reference to the accompanying drawings as follows.

1 is an external perspective view of an elastic flooring mat using foamed olefins to which the technique of the present invention is applied, FIG. 2 is a side view of a mat of elastic flooring using foamed olefin to which the technique of the present invention is applied, and FIG. 3 is applied to the technique of the present invention. 4 is a flow chart of a step showing the first construction method of the present invention, FIG. 5 is a flow chart of the step showing the second construction method of the present invention, FIG. Fig. 6 is a flowchart showing the third construction method of the present invention.

The foamed olefins employed as an environmentally friendly material in the present invention are useful for harmless to the human body and without dust induction, but also have the following problems.

When the weight is applied because the strength is relatively weak compared to other materials, there are dents, scratches, depressions, and the like. Particularly, when constructing a mat shape and bonding a plurality of mats to the floor, there is a depression in the boundary portion, and there are perforations and depressions by women's high heels.

In the case of crushed and reconstituted sheet for recycling the foamed olefin sheet, when the particles of the pulverized product are different from each other and the foaming ratio is used as a base plate after the manufacture of the sheet, the strong cushioning part and the weak part exist depending on the foaming ratio. There is no uniformity of.

Therefore, in the elastic flooring material and the construction method using the foamed olefin of the present invention, using foamed olefin as the base material to increase the environmental friendliness, focusing on the construction method to overcome the weakness of the above-mentioned strength, non-uniformity of elastic strength have.

The elastic flooring material and the construction method using the expanded olefin of the present invention will be described through each of the following examples.

[Preparation of foamed olefin sheet or mat]

In the present invention, in order to overcome the disadvantages of the commercially produced sheet olefin or foam olefin of foamed olefin to increase the strength and elasticity, the foamed olefin is put into a mold after crushing again and manufactured by heating and pressing, and then cut into a certain size mat It may be used by any of.

In the case of manufacturing as a mat, thickness 30-40 mm, width x length 900 mm x 1,800 mm are suitable for construction.

In order to give gloss and waterproofness, at least one of EDPM chip, foamed olefin chip, urethane rubber chip and foamed EVA chip is selected on the upper surface of the mat before or after construction on the bottom surface, Adhesives can be mixed and applied to protect the surface.
