Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eco-

More particularly, the present invention relates to an eco-friendly finishing packaging material and a method of manufacturing the same. More particularly, the present invention relates to an eco- It is possible to melt the thermoplastic polyurethane resin to be contacted with the molten thermoplastic polyurethane resin and to mix the melted thermoplastic polyurethane resin with the hardening earth so as to be easily molded into a predetermined shape to produce an eco-friendly finished packaging material. It is possible not only to prevent the health problems caused by the use of the solvent but also to provide a very environmentally friendly finished packaging material by using the natural earth soil and the non-toxic thermoplastic polyurethane resin And a method of manufacturing the same.

BACKGROUND ART Conventionally, flooring packages such as sidewalks, bicycle roads, and park trails are usually packed with concrete or asphalt on the surface layer, and block packing methods in which various blocks such as stone, brick, cement, and wood are laid on the surface layer.

However, the above method has a problem in that since the strength is strong and there is no elastic feeling, the feeling on walking is hard and the shock absorbing force is low, which may cause injury due to impact.

In order to solve the above problems, it has been recently proposed to use polyurethane resin, EPDM (Ethylene Propylene Diene Monomer) chip, The case of installing the elastic packaging material as a whole is increased.

The elastic packaging material is provided with sufficient elasticity on the floor so that the walking feeling of the pedestrian is improved, and the shock is alleviated to prevent the occurrence of safety accidents. However, in the past, Toxic substances such as volatile organic compounds (VOCs) harmful to human bodies are released from recycled materials such as tire chips and recycled rubber chips, and EPDM chips, which are harmful to human bodies.

Further, the conventional elastic flooring materials, which are formed by bonding together composite materials having different properties such as polyurethane resin, EPDM chip, waste tire chip, and recycled rubber chip, are low in adhesiveness with each other and are packed on the floor, In addition, when a damaged or damaged portion of a conventional elastic packaging material becomes watery or penetrates into the inside of the damaged portion, water and other foreign substances are rotten due to long-term water retention, causing odor And causes various fungi, bacteria, and the like.

In particular, the hygienic problems described above have caused adverse effects on the health of children and elderly people with weak immunity.

Further, the conventional elastic flooring material, which is composed of various materials having different sizes for each material, has a problem in that the texture is rough and there is no stereoscopic effect and it can not be aesthetically pleasing.

In order to solve the above-mentioned problems, the applicant of the present invention has proposed a thermoplastic resin composition comprising 60 to 70% by weight of a urethane ball extruded from a thermoplastic polyurethane (TPU) which is nontoxic and harmless to the human body, 20 to 30% (Korea Patent Registration No. 10-1222553) "which can prevent the release of harmful substances to human body by mixing 5-15% by weight of a solvent.

However, benzene and toluene are generally used as a solvent for securing the flowability of the adhesive, and these solvents must be evaporated in the process of use, but some of them are not evaporated and often embedded in the elastic packaging material. Although benzene, toluene, etc. contain a small amount of substance, they are harmful to the health of children and elderly people with weak immunity because they release substances harmful to human body.

Therefore, it is necessary to develop a manufacturing method of an environmentally friendly elastic packaging material which does not use a solvent.

On the other hand, the conventional elastic packaging material has a problem in that the packaging material is made of a resin-based material having elasticity and excellent in elasticity, but has a low hardness and is somewhat inconvenient to walk.
