进一步地，所述图案层包括电缆规格、型号以及生产日期信息，且图案层为水性色浆图案层。
进一步地，所述蜡乳保护层为阻燃蜡乳层，且蜡乳保护层在＞100℃温度下自然挥发，采用本步的有益效果是当蜡乳保护层蒸发后，图案层会自动显示出来，便于其他人员知晓图案层信息。

步骤S102：进行纤维界面锚固技术处理，选用TiO 2无机纳米粒子对经纱和纬纱的纤维表面有机化修饰，拉伸强度≥200N/2.5cm，在180次/分高频摆动10分钟后测试表面脱粉率＜0.5％；
步骤S103：选用锚固好的涤纶纤维做经纱，密度30-40根/cm，选用锚固好的玻纤纱做纬纱，密度10-16根/cm，采用高速喷水织机制成宽幅1.5-2.1米的匹布，匹布克重80-120g/m 2；

具体实施方式
下面将结合附图对本发明技术方案的实施例进行详细的描述。以下实施例仅用于更加清楚地说明本发明的技术方案，因此只作为示例，而不能以此来限制本发明的保护范围。
需要注意的是，除非另有说明，本申请使用的技术术语或者科学术语应当为本发明所属领域技术人员所理解的通常意义。

实施例1
如图1所示，本实施例所提供的一种可识别耐火包带，包括包带本体1，所述包带本体1的一侧表面设置有防伪层2，高阻燃耐火包带是应于较为苛刻的环境中，在发生火灾时，高阻燃耐火包带能够阻止火势蔓延，防止其进一步扩散至电缆，造成重大损失；而本实施例中在包带外侧涂覆防伪层，该层可以用于和其他产品做区分；因为本实施例的应用环境特殊，为了避免该防伪层2在高温受到破化，影响防伪层2上的标识，所以本实施例中防伪层2是耐高温防伪层，必须要能够耐高温，或者防伪层2内部的标识不会在受到高温或者火焰时发生损坏。
其中，本实施中所述包带本体1为高阻燃耐火包带，同理，本实施例主要是应用于核电、高铁等行业，对于耐高温性能要求非常高，因此包带本体 1需是高阻燃耐火包带。
其中，所述防伪层2包括图案层201和蜡乳保护层202，所述蜡乳保护层202涂覆在所述图案层201的表面；本实施例中的图案层201可以打印上电缆规格、型号、生产日期、厂家等信息，一是方便客户进行选用，二是方便客户进行监督和责任追溯；本实施例添加蜡乳保护层202，所述蜡乳保护层202为阻燃蜡乳层，且蜡乳保护层在＞100℃温度下自然挥发，首先蜡乳保护层202可以起到一定的保护作用，正常使用的情况下，有效避免图案层遭受到磨损，其次，蜡乳保护层202达到一定厚度的情况下，是不透明的，这样能够有效避免产品信息的泄漏，防止他人进行模仿、制造和生产；再次，蜡乳保护层202在高温下(大于100℃)的情况下，会自然挥发，这样图案层就会自动显示出来，便于人员进行追踪和观察，从而确定该包带的信息。
其中，所述图案层201为水性色浆图案层。本实施例中的水性色浆图案层包括沙土，颜色可为红色、黑色、黄色；沙土的成本非常低，从整体上可以降低制造成本，同时也能够降低使用成本；沙土该材质环保，在高温下不会燃烧产生有害物质，同时正常使用情况下，也不会产生有害物质，不会对环境产生影响；沙土能够承受5000℃以上的高温，在高温下，图案层不会受到损坏。
本实施例中对图案层、蜡乳保护层的厚度进行控制，所述图案层的厚度为可以为0.05mm或0.06mm或0.07mm或0.13mm或0.14mm或0.15mm或0.05mm-0.15mm中的任一数值，所述蜡乳保护层的厚度为0.10mm或0.11或0.12或0.13mm或0.14mm或0.15mm或0.10mm-0.15mm中的任一数值，如果图案层厚度较低时，无法长时间保证信息清晰，如果厚度较高，会出现包带分层现象和包带重量较大的问题，影响包带的使用；如果蜡乳保护层的厚度太低，无法起到保护图案层的作用，如果蜡乳保护层的厚度太高，会出现包带分层现象和包带重量较大的问题，影响包带的使用。
实施例2
本实施例公开了实施例1中的可识别高阻燃耐火包带的制备方法，所述可识别耐火包带包括包带本体，所述包带本体的一侧表面设置有防伪层，所述防伪层包括图案层和蜡乳保护层，所述图案层外侧涂覆有所述蜡乳保护 层；
所述可识别耐火包带的制备方法包括以下步骤：
步骤S1：选用高阻燃耐火包带；
步骤S2：利用网纹辊将图案涂覆到高阻燃耐火包带表面形成图案层；
步骤S3：在步骤S2中的图案层表面喷涂阻燃蜡乳液形成蜡乳保护层，然后收卷分切，制成可识别高阻燃耐火包带。
关于步骤S1，对包带本体进行选用，选用为高阻燃耐火包带，针对于其工作的环境，需要承受高温，且还必须要防止线缆点燃，因此包带本体需具备高阻燃和耐火的特性。
关于步骤S2，其中图案层包括电缆规格、型号以及生产日期等信息，在制备时，通过网纹辊进行图案的处理，该方法主要是利用网纹辊凹点上胶工艺，将包含电缆规格、型号、生产日期的图案涂覆到高阻燃耐火包带表面；
关于网纹辊凹点上胶工艺，在凹点涂覆的是水性色浆，是高速纳米研磨机对沙土进行加工，制作的水性色浆，在使用时，先将制作完成的水性色浆涂覆到网纹辊的凹点处，而网纹辊凹点包括以下信息，电缆规格、型号以及生产日期等，最后将图案涂覆至高阻燃耐火包带表面；具体步骤如下，先在圆形辊表面雕刻制成所需的图形，图形是印于圆形辊表面，再在其雕刻制作而成的凹板图形表面，再次运用激光技术在其外表雕刻制作成100-200目网纹，这样更有利于粘胶涂覆，将水性色浆涂覆在上面，然后运用刮刀、上压辊相互配合，将图案层涂覆至高阻燃耐火包带表面。
关于步骤S3：为了防止在高速绕包时，带材在高速绞合的情况下变形，图案会发生脱粉、图案变形的情况，因此需要在图案层的表面添加阻燃蜡乳层，具体的操作方法是进行喷涂，将乳白色不透明的阻燃蜡乳液喷涂至图案层的表面，直至目视不透明为止，待冷却后，形成蜡乳保护层，这样能够起到表面保护、覆盖的作用，可以有效保护图案的完整性，避免图案在绞合过程中，发生损伤；同时阻燃蜡乳液还有个特性，就是高温时，会自然挥发，这样一旦发生特殊情况，例如火灾时，阻燃蜡乳层会接触高温后挥发，此时图案层就会自动浮现，从而知晓线缆、包带一些具体性能参数，便于使用人员进行事故调查和事故追踪。
实施例3：
本实施例是针对于实施例2步骤S1中的高阻燃耐火包带进行的说明，实施例2选用的高阻燃耐火包带并非是现有的常规的高阻燃耐火包带；因为目前在该领域，国内同类产品性能参差不齐，国外其他厂家也没有同时具备无卤型高阻燃耐火包带多性能缆芯包带材料,如美国杜邦、日本东丽公司单一的阻燃、耐火缆芯包带，性能虽然优越，但不同时具备阻燃、耐火、抗老化等多项性能，无法满足中国的核电、高铁等线缆的长寿命要求；因此需要选用一种同时具备阻燃、耐火、抗老化等多项性能的高阻燃耐火包带，所以选用如下结构的高阻燃耐火包带，其具体结构包括功能复合纤维层101，所述功能复合纤维层101的上表面和下表面涂覆有阻燃耐火涂层102，所述功能复合纤维层101与阻燃耐火涂层102之间设置有抗氧化涂层103；本实施例公开的高阻燃耐火包带相比较现有的耐火包带，抗氧化涂层103和阻燃耐火涂层102不一样，本实施例中的抗氧化涂层103是Si-Mo-Cr、乙酯和交联剂甲醛混合制成的涂层，各成分的体积含量如下：
Si-Mo-Cr     15％；
乙酯         80％；
交联剂甲醛   5％。
而阻燃耐火涂层102是由纳米带增韧陶瓷粉体、硅胶、锑类阻燃剂、BPO固化剂、MF甲醛缩合物分散剂和乙酯混合而成的涂层，各物质的重量百分比为：

步骤S105:利用发泡喷涂技术，将表面抗氧化层已处理好的匹布进行阻燃耐火涂层的涂覆，涂覆后表面固含量300±5g/m2，固化后表面厚度达1.5mm；
