Definitions

  • the present invention relates to composite thermoplastic sheets, decorative parts and methods of making same, and more particularly to the field of sheet and decorative parts for eyeglasses. Background technique
  • thermoplastic sheet materials for patterned glasses on the market are generally produced by a screen printing method, and screen printing requires film production, which has high cost and long production cycle. Since the ink used in the screen printing method is low in bonding strength to the sheet, it is necessary to use an adhesive or other solvent such as compound water to enhance the bonding strength.
  • thermoplastic sheet material which is patterned by the transfer technique
  • the application number disclosed in the Japanese Patent Publication No. JP2003-138051, issued on December 2, 2004, refers to the use of thermal sublimation ink thermal transfer printing, but due to ink penetration/smudge In the plastic sheet, the pattern pattern produced is unclear, and the joint strength is low at the time of hot pressing. Moreover, the pattern of the pattern resin plate produced by the method can only be in the middle position, otherwise the adhesion is poor.
  • the composite thermoplastic sheet and decorative parts (such as eyeglass parts) provided by the invention are rich in color, non-fading, and are not affected by external factors, and have a three-dimensional effect. In particular, it is used in the field of sheet metal or decorative parts such as glasses.
  • the processing method for preparing the composite thermoplastic sheet and decorative part of the present invention is simple in process and short in production cycle.
  • the decorative member e.g., the spectacles member
  • the decorative member has a pattern on a plurality of sides, which increases the aesthetics of the spectacles member and satisfies the needs of the art to the utmost extent.
  • One object of the invention is a process for the preparation of a composite thermoplastic sheet for spectacles and a composite thermoplastic sheet obtained according to the method, in particular a composite thermoplastic sheet for spectacles obtained according to the method.
  • the composite thermoplastic sheet is welded by using a high-frequency welding machine to laminate a plurality of layers of thermoplastic sheets having a pattern and/or a substance between layers, such as instantaneous welding, specifically welding the surfaces of adjacent sheets, and strengthening the bonding strength.
  • the pattern is kept intact, resulting in high-definition images.
  • the transferred pattern will not be immersed in any way, thus making the pattern flower
  • the lines are clearer.
  • the physical object located in the intermediate layer does not shift in position while ensuring the state is intact.
  • the present invention relates to the technical solution of the following aspects:
  • a method of preparing a composite thermoplastic sheet for spectacles wherein the composite thermoplastic sheet comprises an upper sheet, a lower sheet, and one or more intermediate layers between the upper sheet and the lower sheet and One or more intermediate sheets selected,
  • the method includes the following steps:
  • thermoplastic upper and lower sheets 1) providing thermoplastic upper and lower sheets

以下将借助优选实施方式和实施例对本发明作更加具体的说明 ,其不 意于以任何方式对本发明构成限制。
在本文中使用时， 术语"热塑性塑料"或"热塑性材料"指任何适用于眼 镜领域并且可实现本发明技术方案的热塑性塑料材料， 例如， 选自醋酸纤 维素、 丙酸纤维素、 尼龙（例如尼龙 -12 )和聚碳酸酯等等的热塑性塑料 材料。
在本文中使用时， 术语"中间层"是指本发明复合热塑性塑料板材中位 于上片材与下片材之间的主要产生装饰性效果的部分，它可以是图案也可 以是实物， 或者两者的组合。 中间层可以独立于片材存在 (例如实物）， 也 可以形成为片材的一部分 (例如图案)。 该中间层不必是热塑性的； 且不必 与片材具有同样大小的面积 ,例如它可以仅仅形成或附着在片材的一部分 表面上； 它也不必具有特定的厚度和体积， 例如可以是油墨在片材表面上 形成的图案， 甚至可以是油墨渗透到片材表面内形成的图案。
在本文中使用时， 术语"图案"是指形成在基材 (如热塑性片材)上的具 有装饰意味的花紋或图形， 其可以通过本领域惯用的形成方法来形成， 例 如印刷、 涂布等等。 并且， 所述"图案"可以是平面图案， 也可以是立体图 案， 例如凸起和 /或凹陷形成的图案， 对于凸起的图案可能需要在相邻片 材的表面上形成相应的凹坑。 优选地， 所述图案通过印刷方法形成， 更优 选通过转印方法形成。
在本文中使用时， 术语"实物"是指可独立存在的、 具有基本固定的外 形的物体， 例如各种天然或人造的装饰件， 如金属片。 所述实物可以是实 心的， 也可以是空心的， 例如可以在内部空腔中填充有液体或固体颗粒。
在本文中使用时， 术语"中间片材"是指位于上片材和下片材之间的热 塑性片材， 其在高频熔接过程中与相邻片材熔接为一体， 对位于其间的中 间层起到固定作用。 所述中间片材还可以充当阻隔层， 以防止复合板材结 合后， 不同颜色层之间的渗透 (例如油墨或色粉等的渗透）导致的渗色现 象， 达到设计所需的清晰外观效果。 此外， 还可以利用所述中间片材将不 同的中间层分隔开， 从而产生图案和 /或实物之间有一定空间的立体效果。 任选地， 所述中间片材还可以具有其它功能， 例如附加的装饰性功能。 所 热塑性塑 在本文中使用时， 术语"高频熔接机"和"高频机"可互换使用， 是指任 何适用于将热塑性塑料材料熔接在一起的高频感应加热设备。 中间层的制作 备得到， 也可以通过例如下 方^获得。 、 ^
1. 当中间层为图案时， 通过如下方法在热塑性片材上形成图案。
利用计算器辅助设计所需的图案花紋， 将所需图案打印至转印材质 上，其中，优选转印材质为纸；打印机使用装有热升华油墨的喷墨打印机， 其中， 打印使用的油墨例如为含有升华性染料的热升华油墨。 为了增加后 续复合板材的结合强度， 优选油墨为水性油墨。 其中， 将所需图案打印至 转印材质上时将空气湿度保持在 45-80%, 甚至 50-70%。
任选且优选地，将打印有图案的转印材质进行烘干去除多余的溶剂和 /或水分， 避免油墨在转印材质上的暈染和 /或渗透， 保证图案在转印材质 上的清晰度的同时， 转印后的图案的清晰度相应得到提高， 烘干温度例如 为 40°C-70°C。
将转印材质上打印有的图案花纹热转印至热塑性片材上，优选转印时 温度是 100°C-250°C , 转印时间例如是 30秒 -200秒。 为了达到较好的转 印效果， 优选地， 将图案转印到薄片材上形成图案层， 这样批量生产的转 印效果稳定， 不易产生色差。 再优选地， 将转印有图案的薄片材烘干， 使 图案以及油墨固定在片材的表面， 防止油墨在表面和 /或向深层渗透晕染， 使得图案清晰度更佳。优选地， 从烘干后的转印材质上把图案转印至热塑 性片材上， 并将转印后的片材烘干。
2. 当中间层为实物时， 通过如下方法将实物固定在热塑性片材上或相邻 热塑性片材之间。 如果实物为薄片状， 可以采用胶粘剂将实物固定在设计的位置， 这样 熔接复合热塑性板材时，实物不会移动，达到设计需要的外形和位置要求。
如果实物较厚， 或有立体效果， 应该根据设计， 在一个片材或两相邻 片材的特定位置制作外形与实物相同或相近的凹坑，将实物摆放在相应的 凹坑位置。 熔接复合热塑性板材时， 实物外形保持完整， 不会移动、 损坏 或变形， 达到设计需要的外形和位置要求； 并且， 易于控制产品质量、 重 复生产、 产品质量达到规模化生产一致性。
3. 当既存在图案中间层又存在实物中间层时
分别通过常规方法或上述 1和 2的方法形成图案和固定实物，其中实 物与图案位于同一片材的相同或相对的表面上，或位于不同片材的相邻或 不相邻的表面上。 实物摆放可以根据设计结合图案固定 （胶粘剂 /凹坑） 在特定位置， 达到图案和实物结合的设计效果， 从而产生图案和实物有独 特的对位效果。 烘干和 /或缩水
本发明中涉及的烘干和 /或缩水处理， 可例如以如下方式实施： 将构成复合热塑性塑料板材的不同片材（上、 中间、 下）放入烘炉中 进行烘干和 /或缩水处理， 去除不必要的成分， 例如水， 并保证产品尺寸 的稳定性。 具体的加工条件， 根据材料和产品要求具体进行调整， 其中优 选烘干温度为 50-150°C , 时间 5-48小时。 高频熔接
本发明复合热塑性塑料板材的高频熔接可例如以如下方式实施： 将上面得到的形成有图案和 /或固定有实物的热塑性片材与其它热塑 性片材进行结合， 该结合使用高频熔接机进行。 优选地， 为了使产品具有 可视的图案和 /或实物效果， 上片材和 /或下片材、 以及任选的中间片材会 才艮据设计选用透明， 半透明的热塑性塑料片材。
将多片热塑性塑料片材根据设计所需按照上片材、任选的中间片材和 下片材的次序叠置，其中至少一片材在待与相邻片材结合的表面上形成有 图案或固定有实物。 采用高频熔接机进行熔接， 根据实际需要控制电流， 熔接时间和冷却时间。 例如， 高频熔接机熔接时间通常是大于 15秒， 优选 大于 20秒， 但小于 5分钟， 优选小于 1分钟， 甚至是 30-50秒。 电流是大于 0.2A, 优选大于 0.5A, 但小于 5A, 优选小于 2A, 甚至是 0.6-1.3A。 控制电 流， 熔接时间需要根据片材的材料、 厚度、 层数和中间层材质（图案， 实 物等）等等进行调整， 从而在达到所需结合强度的同时， 使中间层的外观 保持良好（图案清晰， 实物外形完好以及定位良好）。 为了保持复合板材 的外形， 需要进行冷却， 冷却时间通常大于 0.5分钟， 优选大于 1分钟， 但 小于 5分钟， 优选小于 3分钟， 甚至是约 2分钟。
通过以上不同工艺的改进和控制， 利用热升华油墨打印图案转印技 术， 将图案转印到热塑性片材上， 并采用烘干工艺， 对每个转印工序的产 品进行处理， 再用高频熔接机进行瞬间熔接， 避免了油墨的渗透和 /或暈 染， 由热塑性片材得到的复合热塑性板材图案清晰， 色彩丰富且边缘也可 以具有图案， 并且结合强度也非常好。 下面将结合附图和优选实施方式对本发明复合热塑性塑料板材的制 备方法，以及利用本发明的复合热塑性塑料板材制备多面具有装饰性图案 和 /或实物的装饰部件 （如眼镜部件） 的方法作进一步详细说明。
