Description
본 고안은 종이의 개선에 관한 것으로, 특히 종이와 종이사이에 합성수지 필름을 개재 접합시켜서 된 3중접합의 종이구조에 의해 고도의 인장력 및 내구성을 제공할 수 있도록 된 3중접합구조의 고인장 종이에 관한 것이다.The present invention relates to the improvement of paper. In particular, the high tensile paper of the triple bonded structure which can provide high tensile strength and durability by the triple bonded paper structure which is interposed and bonded the synthetic resin film between the paper and the paper. It is about.
일반적으로 종이는 펄프등의 종이재료를 얇은 단일층의 종이판으로 성형하여 만드는 것이 보통이며, 이러한 일반 단일층의 종이는 재질의 특성상 내구성이 부족하고 특히 인장강도 내지 전단강도가 약해 사용 또는 취급중 잘 찢어지거나 파단되는 등 수명이 짧은 문제점이 있다.Generally, paper is made by molding paper material such as pulp into a thin single layer paper plate. In general, a single layer paper has insufficient durability due to the characteristics of the material, and in particular, it is weak in tensile strength or shear strength, and is being used or handled. There is a problem of short life, such as tearing or breaking well.
이러한 점을 감안하여 종이나 섬유, 수지등의 판지에 인장력을 높이기 위해 이들을 여러 겹으로 접합시켜서 되는 다중합지의 제조 사용이 근래에 제안된 바 있으나 지금까지의 다중합지는 거의 모두 종이시트의 양측면에 합성수지 필름시트를 가열 접합시키는 식의 방법으로 제조되기 때문에 그 제조에 열건조대와 가열히터등이 부착된 복잡하고 공간을 많이 차지하며 고가의 경비가 소요되는 장치를 사용해야 하는 단점을 지니고 있고 특히 열에 약한 재질로 되어 있거나 아주 얇은 두께를 지닌 종이 및 수지 시트의 연속적인 접합은 공정의 특성상 거의 불가능하였다.In view of this point, the manufacture and use of multi-layered papers in which a plurality of layers are bonded to each other in order to increase the tensile strength on paper, fiber, resin, etc., has been proposed in recent years. Since it is manufactured by the method of heat bonding the synthetic resin film sheet, it has the disadvantage of using a complicated, space-consuming, expensive and expensive device with a heat dryer and a heating heater to be manufactured. Continuous bonding of paper and resin sheets of material or very thin thicknesses was almost impossible due to the nature of the process.
본 고안은 이러한 배경에서 연구고안된 것으로, 그 목적은 열접합공정이 필요없이 접착제에 의한 접합공정만으로 제조될 수 있으면서 우수한 인장강도 및 내구성을 제공할 수 있는 새로운 3중접합구조의 고인장 종이를 제공하고자 하는 것이다.The present invention has been researched in this background, and its purpose is to provide a new triple bond structured high tensile paper that can be manufactured by only the bonding process by an adhesive without the need for a thermal bonding process and can provide excellent tensile strength and durability. I would like to.
