Description

Manufacturing method of toilet seat cover fabric by recycling waste PVC {Toilet Cover Fabric Making Method Using Recycled PVC}

The present invention relates to a method for manufacturing a toilet seat cover fabric recycled from waste PVC, and more particularly, to a method for manufacturing a toilet seat cover fabric recycled from waste PVC implemented to manufacture an eco-friendly toilet seat cover using waste PVC.

A large amount of mats are used for safety reasons in homes with children or children's playrooms, and these mats have been manufactured using synthetic resins. Polyvinyl chloride (PVC) is widely used as a representative synthetic resin.

Polyvinyl chloride is widely used as a base resin for various products because it is easy to mold, has excellent strength, and has excellent mechanical properties.

Along with the polyvinyl chloride, various synthetic resins such as PE and PP are used in various ways throughout life and industry as very excellent and useful materials that replace wood, metal and other materials.

However, it is common for these waste plastics to be landfilled or incinerated along with other wastes. However, in the case of waste plastics, due to some components and a large amount of additives, when incinerated or buried, treatment facilities are damaged or dioxins and toxic gases are discharged, causing macroscopic environmental pollution.

Recently, various methods for recycling waste plastics have been sought due to economic and environmental problems.

The biggest problem in recycling these waste plastics is polyvinyl chloride (PVC). Polyvinyl chloride makes it difficult to recycle plastics in all fields such as RPF, incineration, emulsification, and material recycling, as well as environmental issues.

From an environmental point of view, toxic gases and dioxins are organic chlorides that are generated when organic matter containing Cl (chlorine, chlorine) is incinerated. About 57% of the weight of polyvinyl chloride is composed of chlorine, which is the biggest cause of dioxin emission among plastic materials.

In addition, polyvinyl chloride is a thermoplastic resin, but thermal decomposition occurs severely due to a large amount of additives or new compounds are created. Therefore, in the case of waste plastic mixed with polychlorinated vinyl, PET containers as well as CO-PP, GPPS, HDPE and LDPE, etc. It makes it impossible to reproduce the material made of, and even if it is recycled, the value as a product or raw material is lost.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for derivation of the present invention or acquired in the process of derivation of the present invention, and cannot necessarily be said to be known art disclosed to the general public prior to filing the present invention. .
