The electric wire or wire winding drum includes: a drum plate (1130) which is formed in a barrel shape by assembling a pair of unit plates (1135, 1136); the first and second side plates (1110, 1120) which are coupled to both side portions of the drum plate; and fixing bolts (1010) which enable the first and second side plates to be coupled to each other in a state that the drum plate is disposed between the first and second side plates. In particular, the drum plate (1130) and the first and second side plates (1110, 1120) are manufactured by: mixing 78 wt% of polyethylene, 10 wt% of fly ash, 10 wt% of calcium carbonate powder, 1 wt% of bentonite, and 1 wt% of dye to obtain a mixture; melting the mixture in an extruder of 180 to 220°C to obtain a melted mixture; and compression molding the melted mixture by a hydraulic press and a mold, or injection molding the melted mixture by the extruder of 180 to 220°C.

Description

전선 또는 와이어 권취용 드럼재의 제조방법{A wire bobbin manufacturing method}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wire bobbin manufacturing method,

본 발명은 전선 등의 와이어를 권취하는 드럼재의 제조방법에 관한 것으로, 더 상세히는 와이어가 권취되는 통형의 드럼 플레이트와 제1 측판 및 제2 측판을 구성하는 재질의 강도를 개선하고 다양한 색상으로 구성할 수 있는 드럼재를 제공하는 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a drum material for winding wire such as electric wire, and more particularly to a drum material for winding a wire, The present invention relates to a drum material which can be used as a drum material.

일반적으로 전선이나 케이블 등이 권선된 드럼은 권선 재질 및 권선 길이에 따라 전체 중량이 수톤에 이르는 경우도 있어 그 중량에 파손되지 않을 정도의 강도를 갖는 재질로 구성되어야 한다.Generally, drums with wires or cables are to be made of materials having strength enough not to break the weight of the drum due to the winding material and the length of the winding depending on the length of the winding.

한 예로 와이어 권취용 드럼재의 제조방법으로 대한민국 특허등록번호 10-0187903호가 개시되어 있다.For example, Korean Patent Registration No. 10-0187903 discloses a method for manufacturing a drum material for wire winding.

상기 종래 와이어 권취용 드럼재의 제조방법은, 전기절연성, 내수성, 방습성 및 내한성이 있는 폴리에틸렌을 이용하여 케이블 포장용 드럼 및 기차 레일 침목을 제조하는 것으로, 폴라에틸렌 70~75중량%, 석탄재(Fly Ash) 20~25중량%, 분쇄된 왕겨가루 5중량%를 혼합한 다음, 180℃~220℃하의 압출기에서 녹인 후 유압프레스와 금형을 이용하여 압축 성형하거나, 또는 180℃~220℃하의 압출기에서 녹이면서 사출기로 사출 성형한다.The conventional method for manufacturing a drum material for wire winding uses a polyethylene having electrical insulation, water resistance, humidity resistance, and cold resistance to manufacture a cable packing drum and a railway railway sleeping tie, comprising 70 to 75% by weight of polyethylene, 20 to 25 wt% and 5 wt% of pulverized rice husk powder are mixed and then melted in an extruder at 180 ° C to 220 ° C, followed by compression molding using a hydraulic press and a mold or melting in an extruder at 180 ° C to 220 ° C Injection molding is performed with an injection machine.

또 다른 예로 대한민국 특허공개 10-2004-0076356호에는 폐 합성수지재 78~80중량%, 탄소산화물 15~16중량%, 잔량의 초산 나칠렌을 혼합한 다음, 180~200℃의 압출기에서 녹인 후 사출기로 사출 성형하여 드럼재를 제조하는 방법이 개시되어 있다.As another example, Korean Patent Laid-Open Publication No. 10-2004-0076356 discloses that 78 to 80% by weight of a waste synthetic resin material, 15 to 16% by weight of a carbon oxide and the remaining amount of acetic acid or chillin are mixed and then melted in an extruder at 180 to 200 ° C., To thereby produce a drum material.

그러나, 상기와 같은 방법에 의하여 제조된 재질로 이루어진 종래 일반적인 와이어 권취용 드럼은 드럼재의 강도가 취약한 상태에서, 성형 사출, 반제품 보관 등의 편리성을 위하여 2개의 반원형 단위 플레이트로 구성한 후 그 2개의 단위 플레이트를 결합하여 통형의 드럼 플레이트로 구성할 경우 단위 플레이트가 서로 맞닿는 부분이 더 취약해지므로 와이어가 권선 된 후 중량을 이기지 못하고 파손되거나 찌그러지는 구조적인 문제점이 있다.However, in the conventional general wire winding drum made of the material manufactured by the above-described method, the drum is made of two semicircular unit plates for convenience in molding injection and semi-finished product storage in a state in which the strength of the drum material is low, When the unit plates are combined to form a cylindrical drum plate, there is a problem in that the portions where the unit plates abut each other become more fragile, so that the weight can not be overcome after the wire is wound, and it is broken or crushed.
