Abstract

A golf tee molding material using papers and a golf tee produced by the same are provided to produce high-grade golf tees by using papers and metallic coating, to repeatedly use the golf tee due to appropriate brittleness and strength, and to prevent the golf tee from damaging a lawn mower by easily breaking the golf tee by the lawn mower. The golf tee molding material using papers is produced by mixing pulp of 40~60wt.%, polyethylene of 30~50wt.%, corn starch of 5~25wt.%, a lawn growth accelerating agent of 1~3wt.%, and MAH(Maleic Anhydride) of 2.5~4wt.%. The MAH is a binding agent for improving combining force between the pulp and the polyethylene. The lawn growth accelerating agent is a magnesia fertilizer.

Description

종이 소재를 이용한 골프 티의 성형재료 및 이를 이용한 골프티{.} Molding material of golf tee using paper material and golf tee using same {.}

본 발명은 종이 소재를 이용한 골프 티의 성형재료 및 이를 이용한 골프티에 관한 것이다.The present invention relates to a molding material of a golf tee using a paper material and a golf tee using the same.

종래의 골프용 티는 주로 목재나 플라스틱이 사용되었다.Conventional golf tee mainly used wood or plastic.

목재 티는 목공용 선반에 의하여 가공되는데, 목재의 최소 직경이 대략 0.5cm 내외가 되도록 가공하여야 하기 때문에 생산성이 떨어져서 제조단가가 비교적 고가이고, 쉽게 파손되어 재사용이 불가능하여 많은 양이 소모되고, 파손된조각을 수거하는데 상당한 노동력과 시간이 필요하여 수거되지 않는 경우가 많다.The wood tee is processed by a woodworking lathe, which has to be processed so that the minimum diameter of the wood is about 0.5 cm, and thus the production cost is relatively high due to poor productivity. Collected scraps often require considerable labor and time and are not collected.

플라스틱재 골프 티는 자연분해가 되지 않아서 환경오염을 일으키는 요인이 될 뿐만 아니라 처리비용도 만만치 않은 것이 현실이다. 또한 티샷을 할 때에 강한 탄성으로 튀어 올라 골퍼의 신체에 손상을 주는 경우가 있을 수 있으며, 사용 후 수거되지 아니한 티는 잔디 깎는 기계의 칼날을 손상시키는 문제점이 있는 것이다.Plastic golf tees are not decomposed naturally and cause environmental pollution as well as the cost of treatment. In addition, there may be a case that damages the golfer's body by jumping with a strong elasticity when the tee shot, the tee not collected after use has a problem of damaging the blade of the lawn mower.

상기한 문제점을 해결하기 위하여 종이를 이용한 티가 제안되었다.In order to solve the above problems, a tee using paper has been proposed.

이러한 종이 티는 목재 티보다 강도가 현저하게 떨어져서 1회 티샷 후 파손될 수 밖에 없어서 라운딩시 많은 양의 티를 소지해야 되는 불편함이 있었다.This paper tee has a significantly lower strength than the wooden tee, so it can not be broken after one tee shot, which is inconvenient to carry a large amount of tee when rounding.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하여 적절한 취성을 가지고, 환경친화적으로 사용될 수 있도록 종이를 소재원료를 소재로 하는 골프 티를 성형할 수 있는 재료와, 이러한 재료를 이용하여 제조되는 골프 티를 제공하기 위한 것이다.The present invention solves the conventional problems as described above has a suitable brittle, material that can form a golf tee made of a raw material of paper so that it can be used environmentally friendly, and the golf is manufactured using such a material To provide a tee.

이와 같은 목적을 달성하기 위한 본 발명의 종이 소재를 이용한 골프 티의 성형재료는 펄프 40~60중량%와; 폴리에틸렌(HDPE) 20~40중량%와; 옥수수 전분 5~25중량%와; 잔디 생장 촉진제 1~3중량%와; 상기 펄프와 폴리에틸렌의 결합력을 향상시키는 결합제로서 MAH(Maleic Anhydride) 1~4중량%를 혼합하여서 되는 것을 기술적인 특징으로 한다.Molding material of the golf tee using the paper material of the present invention for achieving the above object is 40 to 60% by weight of pulp; 20-40 wt% polyethylene (HDPE); 5-25% by weight of corn starch; 1-3 wt% turf growth promoter; It is a technical feature that the mixture of 1 to 4% by weight of MAH (Maleic Anhydride) as a binder to improve the bonding strength of the pulp and polyethylene.

본 발명의 골프 티는 펄프 40~60중량%와; 폴리에틸렌(HDPE) 40~50중량%와; 옥수수 전분 5~25중량%와; 잔디 생장 촉진제 1~2중량%와; 상기 펄프와 폴리에틸렌의 결합력을 향상시키는 결합제로서 MAH(Maleic Anhydride) 1~4중량%를 혼합하여서 되는 성형 재료를 일정한 형상의 골프티가 되도록 사출 성형이 되는 것을 특징으로 한다.Golf tee of the present invention is pulp 40-60% by weight; 40-50% by weight of polyethylene (HDPE); 5-25% by weight of corn starch; 1-2 wt% turf growth promoter; As a binder for improving the bonding force between the pulp and polyethylene, a molding material which is mixed with 1 to 4% by weight of MAH (Maleic Anhydride) may be injection molded so that a golf tee having a predetermined shape is formed.

또한 본 발명의 골프 티는 펄프 40~60중량%와; 폴리에틸렌(HDPE) 40~50중량%와; 옥수수 전분 5~25중량%와; 잔디 생장 촉진제 1~2중량%와; 상기 펄프와 폴리에틸렌의 결합력을 향상시키는 결합제로서 MAH(Maleic Anhydride) 1~4중량%를 혼합하여서 되는 성형 재료를 일정한 형상의 골프 티가 되도록 압출성형이 되는 것을 특징으로 한다.In addition, the golf tee of the present invention 40 to 60% by weight pulp; 40-50% by weight of polyethylene (HDPE); 5-25% by weight of corn starch; 1-2 wt% turf growth promoter; As a binder to improve the bonding force between the pulp and polyethylene is characterized in that the molding material by mixing 1 to 4% by weight of MAH (Maleic Anhydride) is extrusion molded to become a golf tee of a predetermined shape.

펄프는 사출 및 압출 용도에 적합하며, 친환경적인 단섬유화 및 화학 처리를 하지 않은 그라운드 펄프로서 일반적인 제조공정과 같이 마쇄→조선→정선→제진→찌꺼기 재해리→탈수하는 공정으로 제조된다.Pulp is suitable for injection and extrusion applications, and is an environmentally friendly short fiber and chemically treated ground pulp, which is manufactured in the process of grinding, shipbuilding, fine selection, dust removal, waste disposal, and dehydration as in the general manufacturing process.

상기 펄프에 첨가되는 생분해성 수지는 HDPE와 옥수수전분이 혼합되는 생붕괴성 수지가 사용된다.As the biodegradable resin added to the pulp, a biodegradable resin in which HDPE and corn starch are mixed is used.

폴리에틸렌과 옥수수 전분은 본 발명이 의도하는 생붕괴성 수지의 목적을 실현하게 되는데, 폴리에틸렌은 펄프와 혼합되면서 기존의 합성수지제 골프 티가 가지고 있는 강성 보다 약한 강성과 탄성을 나타내게 되면서, 종래에 종이로 제조되는 골프 티 보다는 우수한 강성을 발휘하여 잔디 깎는 기계에 손상을 주는 일이 없고, 또한 재사용이 가능하게 된다.Polyethylene and corn starch realize the purpose of the biodegradable resin intended by the present invention. Polyethylene is mixed with pulp and exhibits weaker stiffness and elasticity than that of conventional synthetic golf golf tees. It exhibits superior rigidity than manufactured golf tees and does not damage the lawn mower, and can be reused.

옥수수 전분은 수거되지 않은 본 발명에 의한 골프티가 자연 상태에서 쉽게 생붕괴될 수 있는 특성을 제공한다.Corn starch provides the property that golf tees according to the present invention that are not harvested can be readily biodegraded in their natural state.

잔디 생장 촉진제는 수거되지 않은 본 발명에 의한 골프 티가 자연 상태에서 분해된 다음 비료로 사용되어 잔디의 생육을 촉진시킬 수 있게 되는 것으로, 친환경적 비료로 널리 사용되고 있는 고토비료(수산화마그네슘)를 사용하는 것이 바람직하다.Grass growth promoter is to be used as a fertilizer to decompose the golf tee according to the present invention, which is not collected in the natural state, to promote the growth of grass, using a high fertilizer (magnesium hydroxide) widely used as an environmentally friendly fertilizer It is preferable.

PE계 수지는 펄프와 결합성이 좋지 않아서 물성이 우수한 성형물을 얻기 위해서는 적합한 결합력 향상제의 사용이 요구되어지는데, 본 발명의 종이 소재를 이용한 골프 티의 성형재료는 MAH(Maleic Anhydride)소재에 PE를 그라파이트(graghite)시킨 재료를 사용할 경우에 우수한 강성을 발휘하게 된다.PE-based resins do not have good binding properties with pulp, and thus, a suitable bonding force-improving agent is required in order to obtain a molded article having excellent physical properties. Excellent stiffness is achieved when using graphite material.

본 발명의 성형재료에 의하면 친환경적인 소재로 골프티를 제조할 수 있게 되며, 이러한 본 발명에 의하여 제조되는 골프 티는 종이를 주원료로 제작되므로 메탈릭 코팅 등을 이용하여 고급스러운 제품을 생산할 수 있을 뿐만 아니라, 적절한 취성과 강도를 가지고 있어서 반복 사용이 가능하면서도 잔디 깎는 기계에 의하여 요이하게 파손되어 관리 기계에 손상을 주지 않게 된다.According to the molding material of the present invention, it is possible to manufacture golf tees with environmentally friendly materials, and the golf tees manufactured according to the present invention can produce high-quality products using metallic coatings, etc., since paper is made of a main raw material. Rather, it has the appropriate brittleness and strength, so that it can be repeatedly used, but is not easily damaged by the lawn mower and does not damage the management machine.

또한 수거되지 않더라도 시간이 지남에 따라 지표면의 수분과 지온에 의하여 자연적으로 붕괴되어 환경을 오염시키지 않게 되며, 붕괴시에는 잔디 생장 촉진제에 의하여 필드의 잔디가 생장하기에 좋은 여건을 제공하는 효과가 있다. In addition, even if they are not collected, they naturally decay over time due to moisture and temperature on the surface of the earth, and thus do not pollute the environment.In the case of decay, grass growth promoters provide a good condition for growing grass in the field. .
