Problems solved by technology
[0004] However, the polylactic acid resin composition formulated with the above-mentioned polylactic acid resin is difficult to process because it sticks to a banbury mixer when compared with a resin composition prepared from a conventional polyvinyl chloride resin. Blending and kneading, especially when processing films by calendering, it is difficult to process by calendering such as sticking to calendering rolls due to the lack of heat-resistant viscoelasticity at high temperatures
Also, due to the lack of viscoelasticity at the time of high temperature processing, there is a disadvantage that it is difficult to perform the processing work of laminating in multiple layers

Embodiment
[0045] 100 parts by weight of PLA resin (U.S. natural engineering company: Nature works company, 2003D), 20 parts by weight of plasticizer acetyl tri-n-butyl citrate (ATBC, Acetyl Tributyl Citrate, (strain) Aekyung Chemical), 2 Parts by weight of methacrylate monomer as crosslinking agent, 1 part by weight of dialkyl peroxide (dialkyl peroxide) as thermal initiator, and 3 parts by weight of Stearic acid, which is used as a lubricant on rolls, is kneaded in a banbury mixer until the temperature reaches 160° C., thereby initiating a thermally induced crosslinking reaction.
[0046] Then, in order to smoothly carry out the film preparation operation in the calender roll, use a heat roll at 120°C to achieve sufficient mixing before putting it into the calender roll, and then pass it through a filter (strainer) for the purpose of removing impurities and additional kneading, etc. A transparent film with a thickness of 0.20 mm was prepared from the heat-initiated cross-linking kneade...

Abstract
The present invention provides a biodegradable resin composition which is modified through a thermally initiated cross linking reaction and comprising a PLA resin, a thermal initiator, and a cross linked monomer. Also, the present invention provides an eco-friendly biodegradable sheet manufactured by extruding the biodegradable resin composition or by processing the biodegradable resin composition using a calendaring method.
Description
technical field [0001] The present invention relates to a biodegradable resin composition and a biodegradable sheet using the biodegradable resin composition. In more detail, it relates to a biodegradable resin composition and a method for producing a biodegradable sheet using the biodegradable resin composition, wherein the biodegradable resin composition is characterized in that it contains polylactic acid (PLA) resin, thermal Initiator and cross-linking monomer, and modified by thermally initiating cross-linking reaction. Background technique [0002] Petroleum resins such as polyvinyl chloride are widely used in our daily life. In particular, it is widely used for various building interior materials, films or sheets, daily necessities, and the like. The above-mentioned films or sheets are produced by extrusion or calendering using a resin such as polyvinyl chloride. However, since the raw materials are obtained from crude oil, which is a limited resource, etc., the de...
