Description of the Invention: * Technical Field of the Invention - The present invention relates to an environmentally friendly resin composition, and more particularly to a modified environmentally friendly resin composition containing polylactic acid. [Prior Art] With the improvement of environmental awareness, the industry is actively developing various biodegradable materials' and polylactic acid (pLA) is one of the most highly decomposable materials, but it is limited by its The shortcomings of its own mechanical properties and poor stability are currently used in the field of people's livelihood, such as sanitary cups, tableware and cup lids. In order to expand the applicability of PLA, the raw material industry attempts to improve the mechanical properties of PLA by blending. For example, the polylactic acid composition disclosed in the Tw 2〇1〇〇〇7〇ι patent case is pLA. It is blended with polyvinyl alcohol (Polyvinyl aiC0h0l; abbreviated as pVA) to improve the physical strength and crystal stability of the material. For example, the TW 2〇〇916526 patent is a combination of PLA and polyacrylate compounds. Blending to shorten the cycle of molding. However, although there are many kinds of polylactic acid composite resin materials, there is still room for improvement in the properties of Renqi shai·# composite resin materials. Polycarbonate (P〇lyCarb〇nate; referred to as pc) is a kind of plastic material widely used in the industry because of its good physical and chemical properties. It is made into a disc, a curtain protection board and a safety lens. Mobile phone casings, etc., of course, its price is 2〇%~4〇% higher than other commonly used plastics, which causes the cost of the industry to be improved. In order to reduce the cost of the process, some people will make PCs and other raw materials to be the best in the country, especially A lanthanide polyester, such as the 埶201226470 plastic composition disclosed in TW 200738801, comprises a polycarbonate, a vinegar, a nano-clay, and a carrier acid, and is known from page 12 of the specification. The polyester may be a polyester such as Polyethylene terephthalate (abbreviated as PET) and polybutylene terephthalate (PBT). Although the process cost of preparing a material by blending PC with a polyester such as PET may be lowered, the mechanical properties of the obtained material may be much worse than that of polycarbonate, and it is also known that pc and pLA are blended. The material obtained by the mixing may also have poor mechanical properties due to the poor mechanical properties of the PLA itself, thereby affecting the applicability of the material. Therefore, there is still a need to develop an environmentally friendly resin composition that can balance both physical properties and cost. [Invention 1] In order to increase the complexity of PLA, the inventor of the present invention thought of blending PLA with two resins, namely PC and recycled PET, and enhancing the final resin composition by virtue of the good properties of PC and recycled PET itself. Physical properties, lack of, when the three polymers are simply mixed, they can not reach the good physical properties of the period, and the inventors found that the physical properties of the resin composition are poor because the phase purity between different polymers is not good, so (4) A polar functional group-derived: acid-graft-grafted polyolefin elastomer as a mixture of different polymers: a solvent to increase the compatibility of different polymers with each other, and to enhance the obtained resin composition Physical property. Here, the "fourth" of the present invention provides a modified environmentally friendly resin composition capable of achieving both physical properties and cost. 201226470 The modified environmentally friendly resin composition of the present invention comprises a polylactic acid, a DD-polycarbonate, and a polyolefin olefin grafted with a maleic acid liver. The effect is that the present invention 'by adding a polyolefin elastomer grafted with maleic anhydride to increase the compatibility of PLA, recycled PET and PC' and utilizing the different characteristics of the three polymers to produce a complementary effect, thereby making The obtained resin composition is environmentally friendly, and has physical properties such as bending strength, impact strength, and heat distortion temperature in accordance with industry standards, so that the object of the present invention can be achieved. [Embodiment] The modified environmentally friendly resin composition of the present invention comprises a polylactic acid, a polyethylene terephthalate, a polycarbonate, and a maleic anhydride-grafted polyolefin elastomer. Alternatively, the polyethylene terephthalate may be a pure I-p-ethylene dicarboxylate synthesized according to the conventional preparation method, or a recovered polyethylene terephthalate. The pure polyethylene terephthalate is obtained by condensation polymerization of a stearic acid and monoethylene glycol. Alternatively, the polycarbonate may be a pure polycarbonate prepared by prior art methods or a recycled polycarbonate. Preferably, the maleic anhydride-grafted polyolefin elastomer is obtained by using an ethylene copolymer having a repeating unit represented by the following chemical formulas (1) and (II) and maleic anhydride (structure is as follows) The chemical formula (ΠΙ) is obtained by performing / seeing. 201226470 Card H2-CH2)~ (I) Η -(-c-ch2)- (II)

Lu's other example 2 due to the addition of POE-g-ΜΑ, the resulting PC/PET/PLA composite resin composition can be smoothly granulated by the strands, so that the process can be produced, without In the case where p〇E_g_MA was added, as in Comparative Example 4, in the process of granulation of the strand, the phenomenon of breakage occurred, so that the terminal mass production process could not be entered. As for the comparison of Example 2 with the comparative example, although Comparative Example 1 has no impact of increasing the impact strength from 1〇5 to 268 J/m due to the absence of the added PET regrind, the advantage of lower manufacturing cost is reduced. In the second case, the bending strength and the heat distortion temperature showed a tendency to decrease due to the absence of PC addition, especially the heat distortion temperature was greatly reduced from 100 °C to 68 °C. (:, does not meet the actual application requirements. Looking at the above proof, PET, PC, P〇E-g_MA and PLA have the same necessity. If there is no P〇Eg-MA added to the PC/PET/PLA composite resin composition, The mass production of the subsequent process can not be smoothly carried out, so it is not market-promoting. Furthermore, comparing Example 2 with Comparative Example 3, it can be seen that the modified bending strength of Example 2 is improved by 611 kgfW. To 815 kgf/cm2, the impact strength is increased from 26 J/m to 1〇5 J/m, and the heat distortion temperature is greatly increased from 57 201226470 C to l〇5 °C, and PET is both recycled material and PLA. Effectively reduce the carbon emissions of materials to meet the needs of market products. In summary, the present invention by using a maleic anhydride grafted polyolefin elastomer (ie POE-g-ΜΑ in the examples) and PC, Recycling PET and pla to carry out blending and smelting, and then preparing an environmentally friendly resin composition which is good in compatibility and good in mass production and granulation. Therefore, according to different application ends, the environmentally friendly resin composition of the present invention The nature of the project can meet the needs of the industry, and can also be used by using PET. Receipt to reduce the cost of the process, so it can achieve the purpose of the present invention. The above is only the preferred embodiment of the present invention, and can not limit the scope of the implementation of the present invention. The simple equivalent changes and modifications made by the scope of the invention and the description of the invention are still within the scope of the patents of the invention.
