Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sheet-like elastic packaging material,

The present invention relates to a structure of a sheet-shaped elastic packaging material and a method of manufacturing the same. More particularly, the present invention relates to a cushioning elastic panel and a supporting elastic panel formed of an environmentally friendly material harmless to the human body, The present invention relates to a structure of a sheet-type elastic packaging material and a method of manufacturing the same, in which a panel and a supporting elastic panel are fastened with each other and fastened to each other to fix the panel and the supporting elastic panel.

Recently, elastic and permeable packaging materials have been laid on jogging roads, walkways, playgrounds, playground tracks, roadway guides, etc., to form elastic packing layers, thereby relieving unpleasant shocks to the human body and preventing harmful dust, We are trying to prevent accidents and make landing feeling cheerful.

The above-mentioned bottom packing layer is mainly used as a binder for elastomer particles obtained by crushing waste tires, waste of EPDM, urethane rubber, and other elastomer waste having elasticity, and exhibiting various colors with adhesives of rubber or synthetic resin And a pigment or a dye is added to form a packaging layer.

The major components of these packaging materials are chemical substances and solvents that are not natural materials, which cause bad odors. The dusts generated by the abrasion are harmful substances. It is incinerated or remains as a semi-permanent pollutant.

Such a conventional elastic packaging layer is disclosed in Korean Patent Laid-Open No. 10-2005-0007217, entitled " Elastic packing method using a foamable rubber chip ".

In the elastic packaging method, a primer layer (adhesive layer), a foamed elastic layer formed by particles of a foamed material of EPDM or urethane rubber and a binder, and a non-foamed EPDM or urethane chip on a foamed carbon layer are mixed with a binder, The elastic pavement method having such a constitution can form a foamed elastic layer and is excellent in cushioning property. However, since the foamed layer has poor supportability, it is possible to use a roller skating or a bicycle It can be easily broken by the shearing force generated by the momentary stop, and it can be said that a suitable balance of the supporting force and the elasticity is required.

However, the above-mentioned conventional floor coverings have a common point in that most of them are based on a waste rubber chip having elasticity and a binder, and such a packaging material uses a pollution material such as a waste rubber chip although it is significant in terms of recycling waste There is a serious problem in the disposal of the dust due to the wear and the disposal of the packaging material having the end of its life, so that it is a time when the elastic flooring material which reduces the pollution factor is desperately required from the environmentally friendly point of view.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
