Due to the large number of nano-scale crystals inside the glass-ceramic, it has a more stable structure, and a higher-strength cover product can be obtained after chemical strengthening.
  • the equipment and raw materials required for the 3D hot bending process of the mobile phone cover include: 3D hot bending machine, 3D hot bending mold (usually graphite mold) and glass raw materials.
  • the processing technology of 3D hot bending mobile phone cover glass is generally carried out through the following steps: first, the glass plate is formed by methods such as float, calendering and overflow, and then through the steps of cutting and thinning, and then CNC processing, polishing, 3D Processing such as hot bending, 3D polishing and chemical strengthening.
  • 3D hot bending is carried out using a hot bending machine.
  • the hot bending machine includes preheating, forming and cooling stations.
  • the preheating station includes preheating molds and glass sheets. Its function is to promote the uniformity of the temperature inside and outside the glass.
  • the cooling station is through cooling The water quickly cools the mold, so that the glass temperature gradually decreases from the molding temperature to the ejection temperature.
  • the 3D hot bending mold is a graphite mold, which is divided into two parts. In order to ensure the output efficiency of the 3D hot bending process, the time length of each station is required. In the specific operation, the processed and cleaned glass sheet is placed in a 3D mold, and then the mold is placed in a 3D hot bending machine for 3D hot bending according to the preset process.
  • the principle used by the 3D hot bending process is that after the glass or glass ceramic is heated to a temperature near the softening point, it can change its shape under the action of external force, and then undergo rapid cooling and cooling after changing the shape, so that the shape obtained after hot pressing can be Keep.
  • the preheating step in the 3D hot bending process can prevent the glass from being thermally broken at the high temperature during forming.
  • the forming temperature is above the softening point, and the glass is rapidly softened.
  • the pressure is maintained to maintain the shape of the glass sheet before cooling, and the mold is then rapidly cooled by cooling water.
  • the 3D hot bending process is protected by nitrogen throughout the process to avoid mold oxidation.
  • the defects such as cracks on the edge are reduced by CNC, and the upper and lower surfaces of the glass plate are polished by polishing.
  • 3D hot bending of CNC and polished glass sheets can reduce the breakage rate of glass sheets during hot bending.

  • the existing fully crystallized glass-ceramic has higher mechanical strength and hardness, resulting in low machining yield and high production cost of the existing fully crystallized glass-ceramic before hot bending.
  • the softening and forming temperature of the existing fully crystallized glass-ceramic is generally above 700°C, so the 3D hot bending forming temperature must be higher than 700°C.

Therefore, the 3D hot bending of the existing fully crystallized glass-ceramics has extremely high technical difficulties, and it is difficult to achieve the yield required for industrial production by processing the 3D hot bending into a 3D shape.
  • nucleated glass is used for 3D hot bending, because the nucleated glass is in the early stage of hot bending crystallization, the crystals grown on the interface between the crystal nucleus and the glass are The resulting volume shrinkage is very obvious. The more the proportion of crystals grown, the greater the volume change of the product, and the difficulty of size control. Therefore, the nucleated glass will undergo a relatively large volume change during the thermal bending crystallization process, which will affect the shape after forming.

Description

一种3D微晶玻璃及其制备方法和应用 技术领域
本发明涉及玻璃制备技术领域，具体涉及一种3D微晶玻璃及其制法和应用。
背景技术
微晶玻璃作为新一代高强度玻璃，比传统锂铝硅玻璃具有更高性能。由于微晶玻璃内部具有大量纳米级晶体，因此具有更稳定的结构，经过化学强化后可以得到更高强度的盖板产品。
手机盖板的3D热弯过程通过所需要的设备和原材料包括：3D热弯机，3D热弯模具(一般是石墨模具)和玻璃原材等。3D热弯手机盖板玻璃的加工工艺一般是通过下列步骤进行：首先通过浮法、压延和溢流等方法使玻璃板成型、再通过切割、减薄的步骤、之后进行CNC处理、抛光、3D热弯，3D抛光和化学强化等处理。3D热弯使用热弯机进行，热弯机包括预热，成型和冷却工站，预热工站包括预热模具和玻璃片，其作用是促进玻璃内外温度均匀化，冷却工站是通过冷却水快速给模具降温，使玻璃温度逐步从成型温度降低到出模温度。3D热弯模具为石墨模具，分为上下两部分，玻璃片放入模具后经过预热、成型和冷却工站完成整个3D热弯工艺流程。为保证3D热弯工艺的产出效率，每个工站的时间长短都有要求。在具体操作时，是将加工清洗后的玻璃片置于3D模具中，再将模具放入3D热弯机中按照预设的工艺进行3D热弯。
3D热弯工艺所利用的原理是：玻璃或玻璃陶瓷在被加热到软化点温度附近后，可以在外力的作用下改变形状，改变形状后再经过快速降温冷却，使得热压后得到的形状得以保持。3D热弯工艺流程中的预热步骤可以避免玻璃在成型时的高温下受热破裂，成型温度在软化点以上，玻璃快速软化，同时给模具上下表面通过压杆加压使玻璃板弯曲成型，并在冷却前保持压力维持玻璃板的形状，随后模具经过冷却水快速降温。另外，3D热弯工艺全程都由氮气保护，以避免模具氧化。
玻璃板在成型、切割和减薄后通过CNC减少边缘的裂纹等缺陷，通过抛光使玻璃板上下表面呈现抛光效果。CNC和抛光后的玻璃板进行3D热弯，可以减少玻璃板在热弯过程中的破碎率。
发明内容
现有的3D热弯微晶玻璃由完全结晶的微晶玻璃热弯成型，其加工工序流程为玻璃板成型、玻璃板核化和晶化，晶化玻璃板减薄、晶化玻璃板切割、CNC、抛光，当其完全结晶后才进行3D热弯、3D抛光和化学强化等操作。现有的完全结晶的微晶玻璃，其机械强度和硬度更高，导致现有的完全结晶的微晶玻璃热弯前的机械加工良率低，生产成本高。
现有的完全结晶的微晶玻璃软化成型温度普遍在700℃以上，因此3D热弯成型温度必须高于700℃。在热弯过程中，完全结晶的微晶玻璃因受热，其原有的晶相种类、晶体尺寸、折射率、Lab(色度)值、雾度、透过率等会发生很大变化。应用在显示场景中，微晶玻璃色度、透过率将直接影响显示屏分辨率、色域、饱和度等显示效果；应用于摄像头物镜，微晶玻璃的折射率、雾度、透过率，尤其是紫外、近紫外的透过率对照相和摄像的光学系统具有重要的影响，其中紫外、近紫外的透过率较低时，会直接影响成像质量。
另外，现有的完全结晶的微晶玻璃的3D热弯仅仅为达到热弯成型的目的，存在重复晶化，造成能源和时间的浪费。所以，现有的完全结晶的微晶玻璃的3D热弯存在着极高的技术难度，利用其3D热弯加工成3D形态难以实现工业化生产所要求的良率。
但是，如果不采用完全结晶的微晶玻璃3D热弯成型，而是核化玻璃进行3D热弯成型，因为核化玻璃在热弯晶化初期，在晶核与玻璃的界面上生长的晶体所带来的体积收缩量非常明显，增长的晶体比例越多，产品体积变化越大，尺寸控制难度很大，所以核化玻璃在热弯晶化过程中会发生比较大的体积变化，影响成型后的3D热弯微晶玻璃的尺寸精度。
因此，本发明发现采用部分晶化微晶玻璃进行3D热弯，玻璃热弯形变的同时玻璃受热继续晶化达到目标结晶度，减少了3D热弯时的晶化过程，热弯后的3D微晶玻璃尺寸精度更高。
另外，现有技术中在热弯时会控制较短的热压时间，因为热压时间长了会造成微晶玻璃制品表面出现模具印迹，导致表面质量降低，影响良品率。而本发明方法采用部分晶化玻璃原片进行3D热弯处理，部分晶化玻璃原片初始结晶度高，不易产生模具印迹。并且也是由于部分晶化玻璃原片初始结晶度高，因而单位时间内的尺寸形变量在热 压过程中小，因此可以适应更长的热压时间，能更精确地控制3D后的形变量，使得轮廓度的公差波动小，尺寸更稳定。

本发明的有益效果：
1.本发明采用部分晶化微晶玻璃进行3D热弯，玻璃热弯形变的同时玻璃受热继续晶化达到目标结晶度，减少了3D热弯时的晶化过程，热弯后的3D微晶玻璃尺寸精度更高。本发明的3D微晶玻璃的制备方法加工难度小、加工成本低，节约时间成本，同时节约了热处理的能源。采用部分晶化微晶玻璃进行3D热弯，同时避免了现有高结晶度或完全结晶的微晶玻璃的3D热弯时重复晶化的问题。
2. 3D微晶玻璃制备过程中的平磨和抛光是根据需要在3D热弯前进行。3D微晶玻璃的平磨和抛光速度与硬度有关，硬度越大，平磨和抛光的难度就越大，同时所需的时间越长。本发明使用部分晶化微晶玻璃进行平磨和抛光，硬度比完全结晶的微晶玻璃硬度低，玻璃片平磨和抛光加工难度降低，所需的时间减少。
3.本发明的3D微晶玻璃光学性能得到了提升，由于现有的完全结晶的微晶玻璃软化成型温度普遍在700℃以上，在高于700℃的热弯过程中微晶玻璃中晶体会继续长大、剩余的玻璃体再次析晶，存在过度析晶的问题，导致热弯后的微晶玻璃光学性能大幅下降。本发明所述3D微晶玻璃的光学性能为在380-780nm波长光的平均透过率为88-93％，在360-400nm波长光的平均透过率为65-91.5％，所述3D微晶玻璃厚度为0.7mm时的b值(黄蓝值)绝对值为0.1-3.5。
4.本发明的3D微晶玻璃的尺寸精度的控制率得到提升。采用部分晶化微晶玻璃进行3D热弯，玻璃受热继续晶化达到目标结晶度，虽然在此过程中玻璃热弯晶化的的同时会产生形变但该形变由于减少了3D热弯时的晶化过程而变小，利于控制热弯后的3D微晶玻璃尺寸精度。
5.本发明的3D微晶玻璃的良品率得到提升。如果采用核化玻璃或初始结晶度低的玻璃作为3D热弯成型的原材，该原材在热弯成型 的短时间内需要大量析晶，而不同批次间的原材在3D热弯工艺中受到太多变量因素影响，会导致不同批次间的晶体尺寸、晶体种类、晶体比例稳定性差。采用部分晶化微晶玻璃进行3D热弯，其结晶度相对较高，在热弯过程中晶体的生长量较少，减少了可变因素的影响，因而更容易控制不同批次的3D微晶玻璃的稳定性，提升良品率。

步骤5：将部分晶化玻璃原片进行3D热弯处理，热弯工艺采用表2中序号为19的热弯工艺；热弯处理包括3个预热工站，3个热压工站和2个冷却工站。其中第一预热工站的温度为500℃，第二预热工站的温度为550℃，第三预热工站的温度为600℃。第一热压工站的温度为600℃，上压力为0.1MPa，下压力为0.1MPa；第二热压工站的温度为580℃，上压力为0.1MPa，下压力为0.1MPa；第三热压工站的温度为550℃，上压力为0MPa，下压力为0MPa。第一冷却工站的温度为450℃，第二冷却工站的温度为300℃。其中，预热工站，热压工站和冷却工站中每个工站的工作时间相同，为90s，得到3D微晶玻璃样品22E。因热压温度过低，3D微晶玻璃样品22E无法热弯成目标形状。
应用例
对上述实施例1，实施例2，实施例4，实施例7，实施例12，实施例16，实施例22，实施例23，实施例24和实施例25进行化学强化后得到的3D微晶玻璃进行力学参数测定，测试玻璃厚度为0.65，测试所得结果见表3。
使用SLP-2000应力仪测试，设置光弹系数为25.5，折射率为1.54，属于常规测试，测试结果包括表面压应力、压应力深度和平均张应力，张应力线密度为计算值，SLP-2000应力仪测试张应力得和除以玻璃厚度。
表面压应力(MPa)：玻璃经过化学强化后，表面较小半径的碱金属离子被替换为较大半径的碱金属离子，由于较大半径的碱金属离子的挤塞效应，玻璃表面因此产生压应力，称为表面压应力；
压应力深度(μm)：从化学强化玻璃表面到压应力为零的位置的距离；
平均张应力CT-AV(MPa)：根据SLP-2000应力仪测试获得的张应力的和与张应力区域厚度的比值；
张应力线密度CT-LD：根据SLP-2000应力仪测试获得，化学强化玻璃在其厚度截面下，其张应力积分与玻璃厚度的比值；
整机跌落测试：一种强化玻璃强度测试的方法，将强化玻璃片与手机等电子设备样品贴附在一起，由高处自由落体跌下，记录玻璃破碎的高度，这一高度值可以反映玻璃的强度，将此测试方法称为整机跌落测试。本专利测试方法为强化玻璃片负重180g的手机自由跌落在120目的砂纸上，砂纸紧贴于大理石底板上；
维氏硬度(Hv)(300N压力保持10s)：用一个相对面间夹角为136度的金刚石正棱锥体压头，在载荷300N作用下压入被测试样表面，保持10s后卸除载荷，测量压痕对角线长度d，进而计算出压痕表面积，最后求出压痕表面积上的平均压力，即为玻璃的维氏硬度值，用符号HV表示。
表3力学参数测定
Figure PCTCN2022073213-appb-000009
Figure PCTCN2022073213-appb-000010
从上表中可以看出，实施例中经过化学强化后的3D微晶玻璃成品的表面压应力为108-514MPa，压应力深度为109-121μm，平均张应力CT-AV为42-93MPa，张应力线密度CT-LD为30145-43157，整机跌落测试高度为1.51-1.82m，化学强化后3D微晶玻璃成品的维氏硬度(300N压力保持10s)为712-741Hv。
以上所述，仅是本发明实施的较佳实施例，并非对本发明做任何形式上的限制，凡在本发明的精神和原则之内所做的修改、等同替换和改进等，均需要包含在本发明的保护范围之内。
