Abstract
The present invention provides an automobile interior sheet using a bioresin that includes: 5 to 100 parts by weight of a bioresin prepared from a starch extracted from at least one natural plant selected from the group consisting of corn, potato, sweet potato, sugar cane, bamboo, or similarities thereof; 30 to 100 parts by weight of a thermoplastic polyolefin (TPO) resin or a thermoplastic polyurethane (TPU) resin; 5 to 40 parts by weight of a compatibilizer; 0.1 to 1.5 part by weight of a lubricant; and 0.5 to 5 parts by weight of a crosslinking agent.
Claims10
An automobile interior sheet using a bioresin, comprising:
- 5 to 100 parts by weight of a bioresin prepared from a starch extracted from at least one natural plant selected from the group consisting of corn, potato, sweet potato, sugar cane or bamboo;
- 30 to 100 parts by weight of a thermoplastic polyolefin (TPO) resin or a thermoplastic polyurethane (TPU) resin;
- 5 to 40 parts by weight of a compatibilizer, wherein the compatibilizer includes any one compound selected from the group consisting of glycidylmethacrylate (GMA), maleic anhydride (MAH), maleic acid (MA), and ethylene methacrylic methyl acid (EMMA);
- 0.1 to 1.5 part by weight of a lubricant;
- and
- 0.5 to 5 parts by weight of a crosslinking agent.
A method for preparing an automobile interior sheet using a bioresin, comprising:
- mixing a bioresin, a thermoplastic olefin resin or a thermoplastic urethane resin, a compatibilizer, a lubricant, and a crosslinking agent together wherein the compatibilizer includes any one compound selected from the group consisting of glycidylmethacrylate (GMA), maleic anhydride (MAH), maleic acid (MA), and ethylene methacrylic methyl acid (EMMA);
- processing the mixed material into pellets;
- molding the pellets into a sheet using an extruder or a calender;
- and
- curing the sheet material.
