Description of the invention (彳) The present invention relates to the widest polyene flaps, resins, and polysurface resins, which are environmentally friendly plastics and resin additives that are likely to cause biodegradation after being buried or placed after use ( Environmental Protection Additive (referred to as EPAd) and its masterbatch (Enviro_ntal PrOtectbn plastie, __ ^

Environmental Protective Resin (EPR). Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs "Since the twentieth century, the petrochemical industry has brought great convenience to mankind, and its biggest achievement is to bring plastic civilization to the world and change products, but these plastic products have been used for several years. It must be discarded afterwards, and waste = disposal also brings another environmental problem for human beings. In Japan, for example, its waste is attributed to burnt money and nuclear work. The treatment of buried branches accounts for 41%. The combustion in the incinerator will generate unpredictable high heat, which will shorten the life of the incinerator. However, with the landfill treatment, the plastic will not be decomposed for a long time and will release chemicals that may fox human endocrine system. In order to solve the environmental pollution caused by the aforementioned traditional plastics, biodegradable plastics came into being. Biodegradable plastics have the function of ordinary plastics, and after use, they are gradually affected by microorganisms such as bacteria, molds, and algae in the natural world. Decomposes into carbon dioxide, water and other non-remaining substances. Although microorganisms do not easily break down petrochemical polyolefin compounds Aromatic polymer, but as long as almost all carbon-containing substances will eventually decompose, so the defined biodegradable plastic does not have a strict time limit 'expected to completely decompose as soon as possible within the environment. In addition, ^ material Processability is also a condition that must be considered. Whether it can be made into various shapes of products or films, foams, fibers, etc. using injection or extrusion general procedures ^ 539712

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Biodegradable plastics can be roughly divided into natural polymers (Dianfen Department), microbiology Department: chemical synthesis to three. If the governance is differentiated from the age of material development: The first-generation products appeared in the 8Qs, and the representative product is a polyolefin polymer added with powder. After this material is biodegraded, many Wei ’s are difficult ▲, ' Knife solution broken >. The second generation of products appeared in the 1950s. The main products were the starch-based materials introduced by Novavamont, Italy, and Mixian noodles based on PolycaprGlaetGne ^. In the 21st century, the manufacturing technology of bio-knife disentanglement focuses on three directions: reducing production costs, shortening the time required for decomposition, and physical properties of hybrid materials. Looking at the global market, in 1998, the total demand for biodegradable plastics in the three major regions of the United States, Western Europe, and Japan reached U㈣, valued at 9 million US dollars, which is expected to grow to 2003 ^ ¾ & 10,000 mocks. In other words, the growth rate of f from 1 ship to 3 = the average mother year has reached ⑽, and the US demand accounts for about -half of the world's. In the past, a few tons of powder products were dominated, and the Japanese market was dominated by polytechnics. . In order to solve the problem of plastic coffee on the environment, the basic way is to reduce waste. Therefore, since plastic shaft products need more than 10 years to become deformed and aged, these supplies should be discarded after 1G years, and then be buried. Can be decomposed into various soils and re-substances in a short time, or incineration method 4 is also used because it has been partially decomposed, so it can be burned more frequently, and can even be completely burned without generating pollution to the atmospheric environment. _. Under the large-scale mass production of the petrochemical industry, its cost is quite low, and the production = wide, so it is difficult to suppress production, and from the perspective of economics, this type of product has its own material needs, so it is a surplus scale.
