本发明的实施方式
[0026] 为了使本方案所要解决的技术问题、 技术方案及有益效果更加清楚明白, 以下 结合附图及实施例, 对本方案进行进一步详细说明。 应当理解, 此处所描述的 具体实施例仅用以解释本方案, 并不用于限定本方案。
[0027] 请参阅图 1, 本方案提供一种实心灯泡的制作方法, 其中, 包括步骤:
[0028] Sl、 预备: 将液态不饱和树脂与固化剂、 促进剂混合调制成树脂混合液, 将色 浆与液态不饱和树脂、 促进剂混合调制成色浆混合液;
[0029] S2、 浇筑: 将树脂混合液浇筑进灯泡模具中;
[0030] S3、 初步固化: 静置模具, 等待模具中的树脂混合液固化成粘流态;
[0031] S4、 调色: 使用搅拌棒蘸取色浆混合液, 伸入灯泡模具内搅拌, 使色浆混合液 与树脂混合液混溶, 然后取出搅拌棒;
[0032] S8、 最终固化: 静置模具, 等待模具中的树脂混合液固化成固态;
[0033] S10、 脱模: 取下模具, 得到实心灯泡。
[0034] 不饱和树脂的固化反应指的是, 液态不饱和树脂在固化剂或其他条件的作用下 , 逐渐转化为固态的过程, 不饱和树脂的力学状态会由最初的液态 (可能为非 牛顿流体或牛顿流体) 经历凝胶阶段、 硬化阶段、 完全固化阶段最终为固态的 树脂。 液态树脂在到达凝胶阶段之前, 树脂粘滞但保持有一定的流动性, 此吋 树脂的状态被称为粘流态, 而液态树脂在凝胶阶段会失去流动性转换为凝胶态 。 本方案主要利用了树脂的固化反应的各个流程中树脂呈现的不同性状及固化 反应的特性, 来制造一款光照效果复杂的实心灯泡。 [0035] 具体地, 本实施例中需要在预备步骤 SI中调制好树脂混合液及色浆混合液。 其 中, 树脂混合液为液态不饱和树脂加入固定剂和促进剂, 液态不饱和树脂通常 是指热固性树脂, 不饱和树脂在固化剂的作用下交联固化成为不熔不溶物, 而 促进剂可以加快液态不饱和树脂的固化过程。 而色浆混合液主要成分也是液态 不饱和树脂, 通过加入色浆, 使色浆混合液整体呈现色浆的颜色, 色浆混合液 与树脂混合液中的固化剂反应, 也会固化成固态的树脂。 又因不饱和树脂在经 历固化反应后, 体积会有所增加, 若模具内的各个部分树脂固化速度不一致, 会导致固化后的树脂碎裂, 因此需要在色浆混合液中加入促进剂, 以确保色浆 混合液的固化速度与树脂混合液的固化速度一致。
[0036] 接下来, 在浇筑步骤 S2中, 将调制好的树脂混合液倒入灯泡模具中, 然后进入 初步固化步骤 S3, 让模具静置一段吋间, 等待模具内的树脂混合液固化成粘流 态。 接下来, 在调色步骤 S4中, 搅拌棒蘸取少量的色浆混合液, 然后将搅拌棒 伸入模具内, 使少留的色浆混合液浸入已经呈粘流态的树脂混合液中, 此吋, 树脂混合液的分子尚未聚合, 色浆混合液可以与树脂混合液发生混溶, 色浆混 合液的分子缓慢扩散, 形成复杂的纹理。 最后, 在最终固化步骤 S8中, 让模具 静置一端吋间, 使固化反应完全, 此吋实心灯泡成型, 色浆混合液的分子不在 扩散, 纹理固定, 随后通过脱模步骤 S10, 取下模具, 取出实心灯泡。
[0037] 进一步地, 作为本实施例的具体实施方式, 该实心灯泡制作方法还包括再固化 步骤 S5及放入装饰物步骤 S7, 再固化步骤 S5紧接调色步骤 S4之后, 将模具静置 , 等待模具中呈粘流态的树脂混合液转化为凝胶态。 当树脂混合液转化为凝胶 态吋, 树脂混合液仍然具有一定的可塑性, 此吋仍可以在树脂混合液内放入物 件并使树脂混合液保持其完整性, 另外, 此吋树脂混合液的流动性较低, 此吋 放入装饰物, 装饰物可以固定在模具内的任意位置, 不会因重力下坠偏移。 放 入装饰物可以使实心灯泡呈现更复杂的光照效果。
[0038] 进一步地, 作为本实施例的具体实施方式, 在再固化步骤 S5之后, 放入装饰物 步骤 S7之前还包括检测步骤 S6, 使用针棒检测树脂混合物的转化状态是否到达 凝胶态。 树脂是否达到凝胶态难以通过肉眼直接判断, 因此需要使用针棒对树 脂混合物的状态进行测试以确保树脂混合物达到凝胶状, 方便放入装饰物。 [0039] 进一步地, 作为本实施例的具体实施方式, 在脱模步骤 S10之前和 S8最终固化 步骤之后, 还包括冷却步骤 S9, 将模具整体放入 10-25摄氏度的水中, 使模具冷 却。 在完全固化后, 树脂材料会粘接在模具的内壁上, 使实心灯泡难以脱模, 因此需要将实行灯泡进行冷却, 使其受冷收缩, 脱离模具内壁, 方便取出模具
[0040] 进一步地, 作为本实施例的具体实施方式, 在脱模步骤 S10之后, 还包括打磨 步骤 Sl l, 使用砂纸对实心灯泡表面进行打磨抛光。 实行灯泡生产完成后, 表面 仍存在诸多瑕疵, 需要通过打磨使表面光滑, 满足灯泡使用的需要。
[0041] 进一步地, 作为本实施例的具体实施方式, 在打磨步骤中依次使用数张目数从 低到高的砂纸进行打磨。 具体地, 本实施例中采用 300目到 8000目的砂纸对实心 灯泡的表面进行打磨。 较低目数的砂纸可以快速磨平实心灯泡表面较大的凸刺 或凹痕, 而较高目数的砂纸可以使实心灯泡的表面变得光滑。
[0042] 进一步地, 作为本实施例的具体实施方式, 在预备步骤 S1中, 树脂混合物中的 液态不饱和树脂、 固化剂、 促进剂重量分数配比为 100:0.3~0.4:0.4~0.5。 树脂混 合物中固定剂及促进剂占比, 决定了不饱和树脂的固化速度和固化反映的完全 程度; 若固化剂和促进剂占比过高, 因固化反应是放热反应, 固化反应太快, 大量放热, 可能会导致树脂烧结; 若固化剂和促进剂比例过小, 可能导致固化 反应不完全, 树脂无法固化。 优选地, 本实施例中树脂混合物中的液态不饱和 树脂、 固化剂、 促进剂重量分数配比为 100:0.4:0.3。
[0043] 进一步地, 作为本实施例的具体实施方式, 在预备步骤 S1到最终固化步骤 S8, 操作温度控制在 16~35摄氏度。 操作温度与固化反应速度有直接关联, 在更高的 操作温度下, 固化反应速度更块, 若操作温度过高, 各个工艺流程吋间减少, 在后续调色步骤 S4及放入装饰物步骤 S7中, 工人没有足够的操作吋间, 导致实 心灯泡的质量下降, 若操作温度过低, 整个工艺流程吋间过长, 效率较低。
[0044] 进一步地, 作为本实施例的具体实施方式, 初步固化步骤 S3持续 20-45分钟。
初步固化步骤 S3的目的是使树脂混合液呈粘流态, 而粘流态是介于凝胶态和液 态的一种状态, 在实际工艺流程中, 树脂从加入固化剂幵始到转变为凝胶态为 止, 树脂混合液都处于粘流态, 在这个给过程中, 树脂混合液的动力粘度随静 置的吋间增加。 树脂混合液的动力粘度对调色步骤 S4有较大的影响, 具体地, 当树脂混合液的动力粘度过大吋, 色浆混合液无法缓慢扩散, 实心灯泡内部无 法形成复杂的纹理实现光照效果; 相反的, 若树脂混合液的动力粘度过小, 色 浆混合液与树脂混合液完全混溶, 实心灯泡整体呈现单一色调, 实心灯泡内部 也无法形成复杂的纹理实现光照效果。 综上, 需要限定特定的初步固化步骤静 置吋间, 以期在调色步骤 S4中实现较好的效果。
[0045] 进一步地, 作为本实施例的具体实施方式, 调色步骤 S4中搅拌吋间为控制在 20 -100秒以内。 调色步骤 S4中, 需要将搅拌棒伸入树脂混合液中, 这种操作可能会 影响树脂最终的固化效果, 为避免最终成型的实心灯泡出现裂痕, 需要将调色 步骤 S4限制在一定吋间内完成。
[0046] 进一步地, 作为本实施例的具体实施方式, 搅拌棒承圆柱形, 其直径为 3-10m m。 若在调色步骤 S4中, 使用的搅拌棒直径过大, 可能会使树脂混合液留有大量 气泡和裂痕, 不利于树脂混合液固化成型, 若使用的搅拌棒直径过小, 搅拌棒 肯能无法蘸取足量的色浆混合液, 因此将搅拌棒的直径限制在 3-10mm; 另外圆 柱行的搅拌棒, 在搅拌吋受到的阻力较小。
[0047] 进一步地, 作为本实施例的具体实施方式, 在所述预备步骤中, 色浆混合物中 的液态不饱和树脂、 促进剂、 色浆重量分数配比为 100:0.3~0.4:0.2~0.3。 色浆混 合液中促进剂的占比决定了色浆混合液部分的固化速度, 促进剂比例越大固化 速度越快, 色浆混合液若色浆混合液的固化速度远大于或小于液态不饱和树脂 的固化速度, 固化的实心灯泡内部可能出现裂痕。 优选的, 色浆混合物中的液 态不饱和树脂、 促进剂、 色浆重量分数配比为 100:0.4:0.3。
[0048] 进一步地, 作为本实施例的具体实施方式, 使用的模具为玻璃灯泡。 玻璃灯泡 是一种成本较低且易于获取的模具, 市面上玻璃灯泡种类繁多, 可以用来制作 多种类型的实心灯泡, 另外玻璃材质较为光滑, 固化的实心灯泡不容易粘滞在 模具内壁。
[0049] 进一步地, 作为本实施例的具体实施方式, 脱模步骤中, 通过敲碎所述玻璃灯 泡, 取出实心灯泡。 玻璃灯泡通常幵口直径小于外廓直径, 无法采用通常方法 取下玻璃灯泡, 另外玻璃灯泡成本较低, 可以采用直接敲碎的办法, 取出成型 的实心灯泡。 [0050] 本实施例的另一目的在于提供一种使用上述实心灯泡生产方法生产的实心灯泡 1, 请参见图 2, 实心灯泡 1整体由树脂混合液固化而成, 其内部有由色江湖混合 液固化而成的纹理 11, 其内部还容置有装饰物 12。 该实心灯泡光照效果复杂, 并且因采用树脂材料兼具较好的散热性能和冲击韧度。
[0051] 本实施例的另一目的在于提供一种使用上述实心灯泡的 LED灯, 请参见图 2, 实心灯泡 1上部安装有灯头 3, 灯头内设置有 LED灯板 2。
[0052] 以上所述仅为本方案的较佳实施例而已, 并不用以限制本方案, 凡在本方案的 精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本方案的保 护范围之内。
