Description

A method for producing articles using soft waste and articles using soft waste produced by the method of manufacture {A Goods using Waste Elastomer and Product Method of It}

The present invention is to provide a method of manufacturing an article using the soft waste produced by using the soft waste, such as waste soft resin or waste rubber, and an article using the soft waste produced by the manufacturing method.

In more detail, the soft resin or rubber is produced by extrusion of a product using a soft resin or rubber, and then produced by using the product. The present invention relates to a method for manufacturing an article using soft waste produced by recycling waste, and to an article using soft waste produced by the method.

When injection molding non-specific products such as control pads installed inside various electronic products by using soft materials such as soft resins or rubber, and harmless and environmentally friendly such as keypads of mobile phones, Injection rods and sprues (collectively referred to as "sprues") are generated in the space of the inlet and branch pipe together with the injection molded product.

As such, combustible wastes such as sprues that occur when molding products using soft materials such as soft resins or rubbers contain substances harmful to the human body and the natural environment, and therefore, special care must be taken to treat waste soft materials. Therefore, research and technology development for recycling waste soft materials are urgently required.

However, in the related art, waste soft materials such as sprues separated from products manufactured by molding using soft materials such as soft resins or rubbers are not recycled, and are mainly disposed of by landfilling or incineration.

Sprues generated after product molding as described above cannot be buried in the ground because they are not decomposed naturally, and when incinerated, various harmful substances such as dioxins are released due to incomplete combustion and low temperature combustion. It causes problems that pollute the air and the natural environment.

As such, there is an urgent need for the development of technologies for treatment methods other than waste materials such as waste soft materials by methods such as embedding and incineration.

Nevertheless, wastes, such as waste soft materials, are not recycled and are immediately wasted in such a way as to intensify waste.

In recent years, the technology for producing oil using the waste synthetic resin as described above has been proposed in Korea Patent Publication No. 10-2002-72889 (emulsification method and emulsification equipment system of the waste synthetic resin), which is collected waste synthetic resin In recycling the waste, the synthetic resin is thermally decomposed to completely change the chemical composition of the resin, thereby extinguishing the existence itself, and thus, the reuse of the produced synthetic resin becomes impossible.

The present invention is to provide a method of manufacturing an article using the soft waste that can solve the above problems and waste ends, and an article using the soft waste produced by the manufacturing method.

The present invention recycles the soft waste which is discarded after being manufactured and used as sprues and spores of waste soft resins or waste rubbers produced by extruding the products using soft resins or rubber and then molded together with the products. It is an object of the present invention to provide a method of manufacturing an article manufactured using the soft waste produced by using the same and a soft waste manufactured by the method.

Another object of the present invention is to selectively collect only the waste soft resin made of soft material and the waste rubber and the soft waste which is made of the soft resin or rubber and then discarded, and then collect the collected soft waste components. The present invention provides a method for manufacturing an article manufactured using a soft waste product which is not changed at all chemically and can be used again in a state in which a substance of the soft substance is present as it is, and an article using the soft waste manufactured by the method. .

Another object of the present invention is to chemically change the components of the collected soft waste at all, so as not to change the components and properties of the soft substance at all, and to keep the components as they are. The method of manufacturing the article manufactured by using the soft waste, which can be used to manufacture and use articles such as car wash gloves and cushioning pads, and the soft waste manufactured by the method I'm trying to provide supplies.
