Problems solved by technology

However, this alternative material has some problems because the physical properties are problematic, for example, it may be brittle in winter due to its insufficient flexibility; Requires additional use of processing additives, resulting in cost burden; and requires high cost due to production by extrusion and high cost of the material itself, resulting in low economic feasibility

Embodiment 1

[0094] Based on 100 parts by weight of poly(propylene carbonate) resin (SK New Technology Co., Ltd.), 20 parts by weight of linear low density polyethylene (FT400, SK New Technology Co., Ltd.), 5 parts by weight of toughening agent (DAIFATTY-101, DAIHACHI Co., Ltd.), 0.1 parts by weight of a compatibilizer based on polypropylene (BP401, Honam Petrochemical Company), and 1 part by weight of a lubricant (stearic acid, OCI Company) are input in a Henschel mixer (Henschel mixer), and then mixed for 20 minute. The wet-blended mixture was fed into a compounding extruder at 150° C. for granulation. Through a kneading process (mixing roll and warming roll) and calendering process, a sheet semi-finished product is made, and then through a printing, primer and surface treatment process, and a lamination process, thereby preparing a sheet (including a film). However, in the case of 20 parts by weight of the toughening agent, a kneading type mixer was used, and after performing a kneadin...

Embodiment 1-1 to 1-7

[0098] Sheets were prepared by controlling the content of linear low density polyethylene used in the components of Example 1 to 0, 5, 10, 20, 50, 75 and 100 parts by weight, respectively. The results of the physical property measurements are then listed in Table 1.

[0100]

[0101] When a strength improver for linear low density polyethylene is used in the poly(propylene carbonate) resin of the present invention, compared with polyvinyl chloride resin or polyolefin resin, mechanical properties such as tensile strength and tear strength and dimension Stability is greatly improved and exhibits better elongation. When the linear low density polyethylene is used in an amount of 100 parts by weight or less based on 100 parts by weight of the poly(propylene carbonate) resin, high transparency is exhibited. When its content is more than 100 parts by weight, opacity increases and cold resistance decreases. In addition, even when the content of the strength impro...

[0103] Sheets were prepared by using SKflex from SK New Technology Co., Ltd., DAIFATTY-101 from Japan DAIHACHI Co., Ltd., and acrylate from LG Chem Co., Ltd. as toughening agents in the components of Example 1, and their content Respectively controlled at 0, 1, 2.5, 5, 10, 20 and 50 parts by weight. Then the physical property measurement results are listed in Tables 2-4.

[0111] Tougheners used to mitigate the hard and brittle characteristics of poly(propylene carbonate) resins do not affect the physical properties of the sheet until the level of toughener is 50 parts by weight. If its content is more than 50 parts by weight, mechanical strength, especially dimensional stability may deteriorate, but transparency may improve. Even when the amount of toughener used is 1 / 3 times that of phthalate plasticizer used in polyvinyl chloride resin, the desired physical properties can ...

Abstract

Provided is an eco-friendly poly(propylene carbonate) resin composition for a sheet, which is characterized by using a poly(alkylene carbonate) resin developed by efficiently utilizing carbon dioxide, which is a major contributor to global warming, as a main material, and including appropriate additives, such as, a strength modifier, and a flexibilizer, thereby completely solving environmental hazards controversy of the existing polyvinyl chloride resin products; exhibiting excellent mechanical and thermal properties, processability, post processability (printability, embossing and surface treatment, laminating characteristics) and superior anti-flaming property (low smoke density) and elongation characteristics as compared with the existing polyvinyl chloride resin products; and overcoming an extruding production method which is a small-sized production manner, corresponding to a big defect in thermoplastic plastics emerged as substitutes for polyvinyl chloride resin products and thus applying a calendering process method which is a mass production manner.

Description

technical field [0001] The present invention relates to a resin composition for a highly transparent and high-gloss sheet, and more particularly to a resin composition for a high-transparency and high-gloss sheet by using carbon dioxide (a major cause of global warming) effectively Poly(alkylene carbonate) resin as the main material can replace poly(vinyl chloride) materials that emit toxic gases when burned, and at the same time exhibit excellent mechanical properties even without using harmful processing additives, and it can be applied to Extrusion process as well as calendering process, thereby omitting the post-processing process, and thus economical. Background technique [0002] Sheets including films account for about 30% of poly(vinyl chloride) (PVC) products. About 8% of the sheets are manufactured by applying plastisol to a substrate such as paper or cloth that maintains the sheet shape, then heating, and then cooling, or by performing a calendering process. Eth...
