Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with embodiments.
[0012] In order to obtain a 0.6mm conveyor belt, this embodiment uses polypropylene (PP) with strong impact resistance as the main raw material, and polyethylene (PE) material is added in a certain proportion to increase the toughness of the conveyor belt.
[0013] The two materials are fully mixed, dried at 100°C for 30 minutes, and finally produced in a single layer on the extruder according to the required thickness and width.
[0014] The invention solves the problem that the existing conveyor belt for LCD optical film cutting is easy to delaminate and easily causes damage to the knife mold, and has the advantages of no delamination, good toughness, and no damage to the knife mold, and the production method of the conveyor belt is simple and easy. The advantages.
[0015] The above descriptions are only preferred embodiments of the present invention, and are not intended to l...

Abstract
The invention discloses a conveyer belt for LCD (liquid crystal display) optical film cutting and a production method of the conveyer belt. The conveyer belt adopts a single layer structure and is made of polypropylene (PP) taken as the main material and an auxiliary material used for increasing tenacity of the conveyer belt, and preferably, the auxiliary material is polyvinyl. The production method of the conveyer belt comprises the steps as follow: (1), fully stirring the polypropylene taken as the main material and the auxiliary material used for increasing tenacity of the conveyer belt; (2), drying for 30 minutes at 100 DEG C; and (3), performing single-layer production on an extruding machine according to the required thickness and width. The conveyer belt for LCD optical film cutting solves the problem that a conventional conveyer belt for LCD optical film cutting is layered easily and causes damage to a cutting die easily, and has the advantages of no possibility of being layered, good tenacity and no possibility of causing damage to the cutting die; and the production method of the conveyer belt is simple and feasible.
Description
technical field [0001] The invention relates to a conveyor belt, in particular to a conveyor belt for LCD optical film cutting and a production method thereof. Background technique [0002] In the LCD production industry, a large number of optical films such as polarizing film, diffusion film, and brightness enhancement film are used, and the conveyor belt is indispensable in the cutting and forming process of the optical film. [0003] At present, the thickness of the conveyor belt used by the optical film cutting machine is generally 0.6mm, and the width is 1350, 1400, 1480, 1500, 1580, 1600mm, etc. Both Dongcai and Changzhou Tongyu can only produce PET with a maximum thickness of 0.35mm, so the conveyor belts used by optical film cutting machines are produced by double-layer composite methods, mostly using PET / PET or PET / PVC composite technology , the conveyor belt produced in this way is easy to delaminate under the high-speed operation of the machine, and because the m...
