Description

200540204 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to raw materials that can be processed by thermoplastics, and particularly to raw materials that can be naturally decomposed and plastically processed, and a method for manufacturing the same. [Previous technology] Before the petrochemical industry was underdeveloped, materials were mainly obtained from wood, animal fur, and metals. However, the above materials have problems such as difficulty in processing and forming and excessive cost. Concerns over the consumption of earth's natural air-conditioning resources; after the vigorous development of the chemical industry, plastic materials replaced most of the previously mentioned materials; but the nature of plastic materials that cannot be naturally decomposed or not easily decomposed has created environmental protection problems, even burning Toxic gases are generated during processing (such as chlorine when PVC is burned); environmentally friendly plastics are subsequently generated (such as P · P, P · E ·, no toxic gases are generated during burning), but they still need to be burned into carbon water during disposal The compound can be naturally decomposed only after the treatment process has caused inconvenience during waste. [Summary of the invention] The main purpose of this preparation is to provide a naturally decomposable and plastic raw material and its preparation μ. The method can provide a composition made by a commercial supplier to replace the general thermoplastic molding plastic materials (such as P · E 'P · P ·, etc.) and meet environmental protection requirements. # 加 Ϊ ^ ^ The second purpose is to provide a natural decomposable and plastic component system 2 and its manufacturing method. Most of the stone products of the raw materials made by this method: the remaining price of natural plants & (Such as 榖 shells) and other wide objects have greatly reduced costs. In order to achieve the purpose described in the above, the present invention provides a natural separation
