Abstract

The scratch-proof CD consists of CD substrate, laser reading surface, protecting film and printing surface successively from bottom to top, and one layer of ultraviolet transparent hardening paint (Polvcarbonate) is coated onto the back of CD substrate. The utility model discloses simple structure, manufacturing is easy to because protective coating has wear-resisting, resistant scraping, ultraviolet resistance and resistant solvent's advantage, the event can make the utility model discloses difficult production is because of scratch signal interruption, and reads difficult shortcoming.

Description

Scratch Resistant Disc

本实用新型涉及一种防刮损光盘，尤指一种籍由一层涂覆于光盘背面的紫外线透明硬化涂料，使之具备耐刮、耐磨、抗紫外线及耐溶剂优点的光盘。The utility model relates to an anti-scratch optical disc, in particular to an optical disc with the advantages of scratch resistance, wear resistance, ultraviolet resistance and solvent resistance by means of a layer of ultraviolet transparent hardening paint coated on the back of the optical disc.

一般现有的光盘(不论是音乐光盘或影音光盘等)，皆于光盘基片正面由下而上分为镭射读取面、保护膜及印刷面三层所构成。如图3所示。现有光盘的基片a上由下而上分为镭射读取面b、保护膜c以及印刷面d组成。由于背面无任何保护措施，而使基片a背面暴露，容易受刮伤。若光盘的背面遭到刮伤或磨损，如此当读取装置欲读取其资料时，有可能造成信号断掉及不易读取的缺点。Generally, existing optical discs (whether music discs or audio-visual discs, etc.) are all divided into three layers on the front of the disc substrate from bottom to top: laser reading surface, protective film and printing surface. As shown in Figure 3. The substrate a of the existing optical disc is composed of a laser reading surface b, a protective film c and a printing surface d from bottom to top. Since the back side has no protective measures, the back side of the substrate a is exposed and easily scratched. If the back of the optical disc is scratched or worn, when the reading device intends to read the data, the signal may be broken and it may be difficult to read.

又一般欲清洁光盘背面上的脏污，必须用光盘专用清洁剂(一般的ph值约5.5下)，若使用一般挥发性质的清洁剂清洗脏污，极有可能造成对光盘背面腐蚀的可能，而造成光盘的损坏。Generally, if you want to clean the dirt on the back of the disc, you must use a special cleaner for discs (the general pH value is about 5.5). If you use a general volatile cleaner to clean the dirt, it is very likely to cause corrosion on the back of the disc. resulting in damage to the disc.

本实用新型的目的在于提供一种防刮损光盘，它具有耐磨、耐刮、抗紫外线及耐溶剂的优点。The purpose of the utility model is to provide an anti-scratch disc, which has the advantages of wear resistance, scratch resistance, ultraviolet resistance and solvent resistance.

本实用新型的目的是这样实现的：一种防刮损光盘，其中光盘于基片上依序由下而上分为镭射读取面、保护膜及印刷面所构成，于光盘的基片背面适量涂覆一层紫外线透明硬化涂料(Polvcarbonate)。The purpose of this utility model is achieved as follows: a scratch-resistant optical disc, wherein the optical disc is divided into laser reading surface, protective film and printing surface on the substrate in sequence from bottom to top. Apply a layer of UV transparent hardening paint (Polvcarbonate).

依据上述技术方案分析可知，本实用新型结构简单，生产制造容易，并且由于保护涂料具有耐磨、耐刮、抗紫外线及耐溶剂的优点，故可使本实用新型不易产生因刮伤而信号中断，并且读取不易的缺点。Based on the analysis of the above technical solutions, it can be seen that the utility model has a simple structure and is easy to manufacture, and because the protective coating has the advantages of wear resistance, scratch resistance, UV resistance and solvent resistance, the utility model is not easy to cause signal interruption due to scratches , and the disadvantage of not being easy to read.

下面结合附图和具体实施方案对本实用新型做进一步详细说明。Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

图2为本实用新型的剖面图；Fig. 2 is the sectional view of the utility model;

图3为现有光盘立体分解图。Fig. 3 is a three-dimensional exploded view of an existing optical disc.

首先，请先参见图1、2，其中光盘1于基片11上依序由下面上分为镭射读取面12、保护膜13及印刷面14所构成。于光盘1的基片11背面采用旋转喷涂方式适量涂覆一层紫外线透明硬化涂料(Polycarbonate)15；依据上述构造使用时，经由工厂机具适量旋转喷涂于光盘1背面，并由照射UV灯以便涂料硬化并乾燥，面完成附着于光盘1背面，且该涂料15具有耐磨、耐刮、抗紫外线及耐溶剂的优点，故可用一般清洗剂清晰污物，并可避免光盘1受外力刮伤和破坏。First, please refer to FIGS. 1 and 2 , wherein the optical disc 1 is sequentially divided into a laser reading surface 12 , a protective film 13 and a printing surface 14 on the substrate 11 . Apply an appropriate amount of ultraviolet transparent hardening paint (Polycarbonate) 15 on the back of the substrate 11 of the optical disc 1 by means of rotary spraying; when using according to the above structure, an appropriate amount of rotary spraying is applied to the back of the optical disc 1 through factory equipment, and UV lamps are irradiated to facilitate the coating Harden and dry, the surface is attached to the back of the optical disc 1, and the coating 15 has the advantages of wear resistance, scratch resistance, UV resistance and solvent resistance, so it can be cleaned by general cleaning agents, and can prevent the optical disc 1 from being scratched and damaged by external forces. destroy.
