Description

用于证件的共聚酯片材生产的成型方法 The method of forming a co-polyester sheet material for the production of documents

技术领域 FIELD

本发明涉及一种利用共聚酯制备产品的方法,尤其涉及一种生产证件片材的制备方法。 The present invention relates to a method of using a copolyester prepared products, in particular, it relates to a method for preparing a sheet document production. 背景技术 Background technique

据公安部有关部门介绍,现行的居民身份证,作为我国第一代居民身 According to Ministry of Public Security the concerned department, the existing identity cards, as China's first generation of residents who are

份证,已使用了近2 0年。 ID cards have been in use for almost 2 0 years. 第一代身份证为聚酯薄膜密封、单页卡式,釆用印刷和照相翻拍技术塑封而成。 The first generation ID is a polyester film seal, single page cassette, preclude plastic made by printing and photographic techniques remake. 使用的主要制证材料是专用证件纸和防伪透视全息膜,证件只具备视读功能,证件质量和安全防伪性能也较差。 The main material system permits the use of paper documents and security perspective special holographic film, visual document includes only the read function, security documents quality and safety performance is poor. 随着我国改革开放和市场经济的不断发展,随着科学技术的突飞猛进,第一代居民身份证的缺陷和不足愈加显现,越来越不适应当前形势的发展和需要。 With the reform and opening up China's market economy continues to develop, with the rapid development of science and technology, flaws and shortcomings of the first generation of identity cards even more apparent, and more suited to the development needs of the current situation. 主要表现为:受当时技术条件限制,第一代居民身份证科技含量较低,制发周期长,制作质量和防伪性能较差,极易被伪造、变造,致使利用假证和冒用他人证件进行违法犯罪的问题日益突出,直接危害社会治安和经济秩序,同时也不利于保护公民合法权益。 Mainly as follows: by the time the technical constraints, the first-generation resident ID card is low-tech, issued by long period, the production of poor quality and security features, can easily be forged or altered, resulting in the use of false and fraudulent use of another person issue certificates of criminal conduct have become increasingly prominent, directly endanger public order and economic order, while not conducive to protecting the legitimate rights and interests of citizens.

随着我国换发第二代居民身份证工作正式启动,引人注目的新身份证将很快出现在居民手中。 With the renewal of the second generation ID card was officially launched, compelling new identity cards will soon be in the hands of residents. 第二代居民身份证是由多层聚酯材料复合而成的单页卡式证件,采用非接触式IC卡技术制作,具备视读和机读两种功能。 The second generation ID card is a composite material made of a multilayer polyester single-page document card, non-contact IC card technology production, comprising eye and machine read two functions. 与第一代居民身份证相比较,第二代居民身份证采用了多项新技术和新的防伪措施,证件质量、安全防伪性能大大提高。 Compared with the first generation of identity cards, the second generation ID card using a number of new technologies and new security measures, quality documents, security features, performance is greatly improved. 首先,证件芯片采用数字防伪措施,用于机读信息的防伪;新二代居民身份证将持证人的相片图像和登记项目等内容数字化后采用数码技术加密,存入机读芯片;芯片在证卡内封装,能够保证证件在各种环境下正常使用,可在证件进行机读时完成证件与机具的相互认证和机读信息的安全性确认,有效起到证件防伪的作用;其次,证件表面采用防伪膜和多项印刷防伪技术;防伪膜采用具有自主知识产权的定向光变色膜等技术,印刷防伪技术包括底纹精细、縮微、彩虹印刷、荧光印刷等。 First, the chip uses a digital certificate security measures for security machine-readable information; the new second generation ID card holder's photograph and image content and registration of projects using digital technology to encrypt digitized, stored in a machine-readable chip; chip card within the package, to ensure the normal use of the document in a variety of environments, and acts to complete the document and implement mutual authentication security profile reading machine when the machine readable, document security functions effectively in documents; secondly, documents and the security film surface using a number of security printing technology; security film photochromic film orientation technique using proprietary, fine security printing technique includes shading, microfilm, rainbow printing, fluorescent printing.

该居民身份证所使用的卡基材料采用的是具有绿色环保性能的PETG新材料。 Kaji material used in the identity card uses a new material PETG with green performance.

共聚酯PETG是一种以1、 4-环己烷二甲醇(CHDM)进行共聚改性得到的聚酯,是一种非晶型共聚酯,其制品高度透明,抗冲击性能优异,特别适宜成型厚壁透明制品,其加工成型性能极佳,能够按照设计者的意图进行任意形状的设计,可以釆用传统的挤出、注塑、吹塑及吸塑等成型方法,可以广泛应用于板片材、高性能收縮膜、瓶用及异型材等市场,同时其二次加工性能优良,可以进行常规的机加工修饰,该种共聚酯通过美国FDA关于食品接触标准,可以应用于食品、医疗卫生等领域。 PETG is a copolyester performed in 1, 4-cyclohexanedimethanol (of CHDM) a polyester obtained by copolymerization modification, is an amorphous copolyester which is highly transparent products excellent in impact resistance, particularly suitable thick-walled transparent molded article, excellent molding processability properties, can be any shape designed according to a designer's intention, can preclude the use of conventional extrusion molding method, injection molding, blow molding plastic and the like, it can be widely used plate sheet, high performance shrink films, bottles and other profiles market, while its secondary processing performance, conventional machining can be modified by the kind of copolyester U.S. FDA food contact standards, can be used in food, health and other fields. 根据不同应用领域的特殊要求,采用不同的改性配方,可以应用于多种塑料制品。 According to the special requirements of different applications using different modified formulations may be applied to a variety of plastic products.

另外共聚酯PETG是一种综合性能十分优异的环保型高分子材料,该材料可以回收再利用,而且对周边环境不构成任何污染;此外,PETG新材料采用新配方和控制技术,易于印刷,热稳定性强,具有防伪造、耐摩擦、抗腐蚀、抗静电等特点。 Further PETG copolyester is a very excellent overall performance environment-friendly polymer material that can be recycled, but also does not cause any pollution to the surrounding environment; Moreover, PETG use of new materials and new control recipe, easy to print, strong thermal stability, anti-counterfeiting, abrasion, corrosion-resistant, anti-static characteristics.

把共聚酯PETG材料用于我国新一代居民身份证的卡基材料,必须经过一定的成型方法制得不同要求的卡基用和面层用片材。 The material of the card material PETG copolyester for the new generation of identity cards, the method must go through a molding obtained by the different requirements of the card and the facing sheet.

目前用于PETG片材生产的成型方法主要是挤出流延法,但是如果采用挤出流延法生产,必须投入大量经费购置新设备,增加了成本;如何利用原有的设备,而又能制造出片材是摆在技术人员面前的问题。 Forming methods currently used for the production of PETG sheet extrusion casting method is mainly, but if the extrusion casting method of production, must invest a lot of money to purchase new equipment, increasing the cost; how to use the existing equipment, and can create a sheet is placed in front of technical personnel problems. 发明内容 SUMMARY
