Embodiment 1

[0090]The biodegradable composite resin composition with improved low-temperature processability is obtained by adding 50% by weight of polylactic acid, 10% by weight of polycaprolactone, 5% by weight of polybutylene succinate, 15% by weight of Polyadipate / butylene terephthalate, 15% by weight polyvinyl acetate, 3% by weight crosslinking agent, 2% by weight compatibilizer, and melt-extruded with a twin-screw extruder, thereby carrying out Granulated. Then, after molding the obtained pellets at a temperature of 23° C. and a bar of 3.2 mm according to ASTM D256, and measuring the notched Izod impact strength of each bar according to ASTM D256, it is shown in the following Table 2 .

Abstract

The present invention relates to a bendable splint and a molding method thereof. According to an embodiment of the present invention, a bendable splint may be provided, the bendable splint comprising:a lower splint portion having multiple first aeration holes formed at constant intervals; an extension splint portion having multiple extension holes formed at constant intervals; and an upper splintportion having multiple second aeration holes formed at constant intervals, wherein the lower splint portion, the extension splint portion, and the upper splint portion are bent into a circular arc shape by primary bending, and the extension splint portion enables, by means of the multiple extension holes thereof, the lower splint portion and the upper splint portion to be secondarily bent at different angles.

Description

technical field [0001] The present invention relates to a splint and its forming method, and more particularly to a bendable splint and its forming method. Background technique [0002] Generally, splints are used for protection, to support and immobilize injured joints and muscle tissue by partially or completely tightly wrapping the injured joint and muscle tissue to prevent movement during fractures or fractures and when ligaments are stretched and ruptured. In the past, a method of wrapping and fixing a plaster-coated bandage on the affected area has been widely used, but this application method cannot effectively support the affected area due to shrinkage during the hardening of the plaster, and may cause itching when used for a long time due to airtightness, And it is necessary to use an additional cutter to remove it after finishing the treatment of the affected part, so it may cause skin damage during the cutting process. [0003] In order to solve the problems of t...
