Description

一种曲面反射镜及其制造方法 技术领域
本发明涉及玻璃制品及加工领域， 尤其涉及一种应用于太阳能领域的 曲面反射镜及其制造方法。 背景技术
目前， 在许多工业装置中， 尤其是在太阳能聚光系统中， 经常会用到 各种不同形状的聚光反射镜。 聚光反射镜主要有槽式抛物面反射镜、 曲面 抛物面反射镜、 曲面球面反射镜等。
在太阳能聚光应用中， 对反射镜的光学性能要求往往低于一般光学镜 片， 因此太阳能反射镜面的制造往往不使用传统的镜面磨制法， 以降低制 造成本。
现有曲面镜通常是釆用人工胶粘方法将多个小薄玻璃镜片黏贴到较 大曲面玻璃上。 这种通过将薄玻璃小片散布在粘结结构的曲面镜上所制作 出的曲面镜， 镜面聚光性能差， 镜面反射精度低， 且各薄玻璃小片与胶之 间多有气泡， 因此耐候性及耐腐蚀性能也较差， 影响使用寿命。 此外， 这 种结构曲面镜的制作需要先将大薄玻璃镜切割成多个小片， 然后再将该玻 璃小片黏贴在比较大的曲面玻璃上， 工序多且复杂， 费工费时， 人工操作 繁瑣， 直接导致产品产量小， 制作成本高， 不适于大规模系列化生产。 并 且如果粘胶不均勾， 还可能使反射镜表面形貌变差， 反射精度变低， 无法 达到较高的聚集比， 产品质量无法得到保证。
通常情况下， 曲面反射镜是通过将平面镜或平面玻璃进行变形而得 到。 曲面反射镜成形工艺有两大类： 一类是高温热变形制造法， 另一类是 机械冷变形制造法。
高温热变形制造法是先将玻璃加热到软化状态， 然后在模具里成形， 成形后玻璃坯料再进行反射层镀膜和保护层喷涂。 这种工艺的制造成本相 当高昂。
机械冷变形制造法是将平面玻璃镜通过机械挤压方式紧贴在曲面镜 托上， 使玻璃镜按照镜托的曲面形状发生机械变形， 并且镜子和镜托之间 由粘结剂或机械固定， 以形成曲面反射镜。 这种方式制造的曲面反射镜的 曲面比用高温变形法便宜， 但镜托与曲面反射镜不具备一致的温度膨胀系 数。 并且此种机械冷变形制造法所制造出的曲面反射镜， 由于使用了粘结 剂或机械进行固定， 因此会使镜子背面的保护漆暴露在空气中。 长时间在 户外使用此种反射镜，会发生反射层被腐蚀现象，减小了反射镜使用寿命。
申请号为 200810105690. 1 ,发明名称为一种具有高度镜面反射镜的曲 面反射镜及其制作方法的中国专利申请， 公开了一种利用一层曲面玻璃和 一层平面薄玻璃镜组成的曲面玻璃。 然而该方案所使用的曲面玻璃仍利用 热弯技术获得， 成本很高。
申请号为 200910302460. 9 ,发明名称为一种用于太阳能定日镜的曲面 反射镜的制造方法的中国专利申请， 公开了一种制造曲面反射镜的方法。 在该专利申请中， 每片反射镜由平面反射镜和镜托组成， 并通过高温加热 使之固定， 然而由于镜托与曲面反射镜的膨胀系数不一致， 因此会导致冷 却后收缩不一致， 固化效果降低， 并且在使用此种反射镜过程中还可能会 出现脱胶现象。 此外， 这种方法在曲面反射镜制造过程中需要经历高真空 压力， 因此要求镜托结构的强度很高， 否则会影响曲面精度。 而每片反射 镜面都需要一个高强度和高精度的镜托， 不利于大规模生产， 成本不易控 制。 发明内容

图 1是根据本发明一个实施例的曲面反射镜横截面剖视图。 图 1中， 该曲面反射镜 2由平面玻璃 6、 中间粘结层 7和平面玻璃镜 8进行固化成 型而形成复合结构的曲面反射镜。
具体地， 该平面玻璃镜 8可选用优质浮法平面玻璃镜本体， 且优选为 厚度是 2mm的钢化玻璃。 该平面玻璃 6的厚度优选为 3mm。 该中间粘结层 7可选择优质的乙烯醋酸乙烯酯共聚物（EVA )片、 聚乙烯醇丁醛（PVB)片。 或者该中间粘结层 7也可选用由优质的 EVA、 PVB片和加固定型物所组成 的粘结层。 或者该中间粘结层 7还可釆用由液态光固化胶和加固定型物所 组成的粘结层， 如该液态光固化胶为 UV胶黏剂。 或者该中间粘结层 7选 用由塑料薄膜如聚氯乙烯 （PVC ) 与普通化学粘结剂组合而成的粘结层。 或者该中间粘结层 7 选用由普通化学粘结剂和加固定型物所组成的粘结 层。 或者该中间粘结层 7直接选用普通化学粘结剂。 其中， 该普通化学粘 结剂可以是单组分、 双组分或多组分的粘结剂。 在本发明的一个实施例中，平面玻璃 6和平面玻璃镜 8为非钢化玻璃。 优选地， 中间粘结层的厚度为 Q. 1毫米到 2毫米。 优选地， 釆用非钢化、 不磨边的普通玻璃制备曲面反射镜结构。 釆用非钢化玻璃减小钢化前处理 的磨边难度；此外， 釆用非钢化玻璃成本低廉， 且对环境无污染； 且釆用 非钢化玻璃可以获得更好的曲面反射镜成型， 保证了更高的精度和更轻体 的曲面反射镜。
需要特别注意的是， 本实施例的曲面反射镜由于釆用双层玻璃平面结 构进行压合而成， 因此制造完成后的曲面反射镜具有一定回弹量， 为了解 决此问题， 可釆用以下几种方式：
( 1 ) 制造完成后的曲面反射镜在曲率、 尺寸方面都要略大于所需要 的曲面反射镜， 以补偿曲面反射镜成型后的回弹量；
( 2 ) 中间粘结层釆用加固定型物作为胶层的支撑结构， 使平面玻璃、 平面玻璃镜、 中间粘结层具有一致的参数， 使该曲面反射镜在工作过程中 具有良好的热稳定性能； 并且该加固定型物还增强了平面玻璃、 平面玻璃 镜与中间粘结层的粘结支撑作用， 且增强了抗平面玻璃和平面玻璃镜欲回 弹变形能力， 减少了曲面反射镜制造完成后的回弹量， 提高了曲面反射镜 的稳定性， 延长了产品使用寿命。
本实施例优选釆用加固定型物于双层平面玻璃中间固定， 因为加固定 型物具有吸附性能， 其可以降低胶层的流动性， 保证胶层均勾性。 在传统 平面玻璃成型过程中， 平面复合玻璃胶水在双玻璃间可实现胶水的均匀分 布。 但若为曲面成型加工， 因胶水具有流动性， 一般方法无法达到胶水均 匀分布。 因此本实施例在中间粘结层中增加了加固定型物， 以吸附胶水， 使胶水沿曲面均匀布置在两层玻璃中间， 达到胶水均布的目的。 因为加固 定型物布置于双平面玻璃之间， 因此成型后三者可形成一个整体， 进而增 强了粘结支撑作用， 提高了抗平面玻璃和平面玻璃镜欲回弹能力， 减少了 曲面反射镜制造完成后的回弹量。
因为在曲面反射镜制造过程中， 曲面反射镜的曲率与曲面支撑装置、 平面玻璃、 中间粘结层、 平面玻璃镜的厚度有直接关系， 因此保证中间粘 结层的厚度至关重要。 加固定型物可以有效控制中间粘结层的厚度， 以方 便控制曲面反射镜制造精度。 此外， 加固定型物还可以支撑平面反射镜， 增强曲面反射镜的机械性能。 并且将加固定型物布置于双平面之间， 降低 了产品破损率。 当曲面反射镜破裂时， 加固定型物可粘附玻璃碎片， 从而 减少了对操作人员和附近曲面反射镜面所带来的危害。
图 2是根据本发明一个实施例的反射镜整体结构立体示意图； 为了进 —步保证曲面反射镜 2的定型精度，将该曲面反射镜 2固定于镜托 1内部， 从而形成了反射镜整体结构。
图 2 中， 该反射镜整体结构包括镜托 1、 曲面反射镜 1 (具体结构参 见图 1 ) 、 曲面支撑架 3。 该镜托 1靠近曲面反射镜 2的一个面为曲面， 且该曲面的曲率和尺寸与所需曲面反射镜 2背部曲面的曲率一致。 此外， 该曲面反射镜 1端边或全部布置于该镜托 1之上， 并由该曲面支撑架 3所 支撑和固定。 由于镜托曲率和尺寸与所需曲面反射镜相同， 并且可支撑和 固定该曲面反射镜， 因此其可提供给曲面反射镜更高的机械强度， 延长曲 面反射镜的使用寿命。
图 3是根据本发明一个实施例的曲面反射镜所需材料的分解示意图。 现以开口（弧形两端点之间的直线距离）为 1. 2m,长为 2. 4m,弧长为 1. 22m 的曲面反射镜为例， 对图 3进行详细阐述。
图 3中， 该曲面反射镜所需材料分别为曲面支撑架 3、 镜托 1、 平面 玻璃 6、 中间粘结层 7、 平面玻璃镜 8。
该曲面支撑架 3的曲率、 尺寸与该曲面反射镜 2背面的曲率、 尺寸一 致。 该曲面支撑架 3开口稍大于该曲面反射镜的开口， 即该曲面支撑架 3 开口稍大于 1. 2m, 且两相邻曲面支撑架的中心距离为 2. 4m。
该平面玻璃 6的尺寸为 1. 22m长， 2. 4m宽， 3mm厚， 且该平面玻璃 6 的材质为钢化玻璃。
该中间粘结层 7可以是热熔胶片， 且其釆用的是耐候性较好的优质乙 烯与醋酸乙烯脂的共聚物 （EVA ) 、 聚乙烯醇缩丁醛（PVB ) 。 并且该热熔 胶片的尺寸要比该平面玻璃 6尺寸稍大些， 如该热熔胶片尺寸为 1. 25m x 2. 5m。
该中间粘结层 7也可以是热熔胶片和加固定型物， 且该热熔胶片布置 于该加固定型物之上。 并且该加固定型物尺寸比该平面玻璃 6的尺寸稍大 些， 如该加固定型物尺寸为 1. 25m x 2. 5m, 且该加固定型物材质为玻璃纤 维布或无纺布。
该中间粘结层 7还可以通过将液态光固化胶（如液态 UV胶黏剂 ) 涂 覆于加固定型物上而形成该中间粘结层。 并且该加固定型物尺寸要比平面 玻璃 6尺寸稍大， 如该加固定型物尺寸为 1. 25 m x 2. 5m。
该中间粘结层 7也可以釆用普通化学粘结剂， 且该普通化学粘结剂为 单组分、 双组分或多组分粘结剂。 此外， 该中间粘结层 7也可以是普通化 学粘结剂和加固定型物， 以使该平面玻璃镜 8与该平面玻璃 6完全粘结合 并紧密均勾地结合为一体。 此种釆用普通化学粘结剂的中间粘结层， 成本 低廉且操作简单， 不过效果不是最理想。
该平面玻璃镜 8尺寸厚要比该平面玻璃 6尺寸厚度稍小些， 如该平面 玻璃镜 8的尺寸为 1. 2m X 2. 4m , 厚度为 2mm。
图 3中， 该镜托 1的曲面向上， 该平面玻璃镜 8的镜面 （涂有反射层 的一面）朝下且其紧邻中间粘结层 7。 此种将涂有反射层的反射面置于内 部的方式， 大大减少了涂层的磨损和破坏。
以上所述图 1至图 3中的平面玻璃是一层平面玻璃结构。 实际上， 该 平面玻璃并未被限定为一层平面玻璃结构， 该平面玻璃可以是多层平面玻 多层平面玻璃结构做详细阐述。
图 4是根据本发明另一个实施例的曲面反射镜的立体结构示意图。 该 曲面反射镜包括平面玻璃镜 8、 中间粘结层 7和平面玻璃结构。 其中， 该 平面玻璃结构包括第一平面玻璃 1 3、 粘结层 20、 第二平面玻璃 1 2。
需要说明的是， 该平面玻璃结构不限于图 4所示的两层结构， 即本发 明未被限定在仅包含第一平面玻璃 1 3、 第二平面玻璃 1 2 , 还可以包含多 层平面玻璃， 从而形成多层平面玻璃结构。
图 4中， 平面玻璃结构由两层平面玻璃（即第一平面玻璃 1 3、 第二平 面玻璃 1 2 )通过粘结层 20形成曲面后固定； 且该粘结层的具体结构、 工 作原理与前文所述中间粘结层 7的结构及工作原理相同。
图 4 中， 该平面玻璃结构 （包括第一平面玻璃 1 3、 粘结层 20、 第二 平面玻璃 1 2 )位于该平面玻璃镜 8之下。
在本发明的一个实施例中， 该两层平面玻璃尺寸不同， 且位于底部的 第二平面玻璃 1 2的尺寸大于位于顶部的第一平面玻璃 1 3的尺寸。 并且该 第一平面玻璃 1 3规律地布置于该第二平面玻璃 1 2之上， 受压定型后， 通 过连续大尺寸的粘结层 20 固化后形成曲面双层平面玻璃结构。 而与该第 一平面玻璃 1 3尺寸相近的该平面玻璃镜 8在长度方向 （即轴向方向） 上 相互错位地布置于该双层平面玻璃结构之上， 然后通过连续大尺寸的粘结 层 20固化后形成曲面反射镜。
在本发明的另一个实施例中 （图 4并未示出） ， 双层平面玻璃结构的 第二平面玻璃 1 2和第一平面玻璃 1 3的尺寸与该平面玻璃镜 8的尺寸相同。 三片玻璃（即第二平面玻璃 1 2、 第一平面玻璃 1 3、 平面玻璃镜 8 )在轴向 方向上相互错位地布置， 受压定型后， 每层曲面之间通过连续大尺寸的粘 结层 20 固化后形成曲面反射镜。 该多层平面玻璃结构的曲面反射镜可以 在同一过程中完成大尺寸的曲面成型和固化。
由此可见， 具有多层平面玻璃结构的曲面反射镜的曲面精度更高， 可 釆用更薄的单片平面玻璃和平面玻璃镜弯曲以获得更高曲率， 同时还能够 达到较高的机械强度。 并且通过错缝排列粘接方式， 可以用较小尺寸的玻 璃组合粘接得到单个大尺寸的曲面镜， 以扩展应用范围。
此外， 该具有多层平面玻璃的曲面反射镜在同一过程中完成曲面成型 和固化。
图 5是根据本发明一个实施例的反射镜整体结构制作工艺流程图。 在步骤 51 0 , 材料的制作、 选取及相应准备工作， 包括曲面支撑装置 的制作， 以及平面玻璃 6、 中间粘结层 7、 平面玻璃镜 8的选取及准备。
需要说明的是， 所述曲面支撑装置是在形成曲面反射镜过程中， 用于 存放、 固定及制作该曲面反射镜的装置； 而前文所述曲面支撑架 3则是在 该曲面反射镜成型后并在其工作过程中， 用于固定及支撑该反射镜的装 置。
该曲面支撑装置的形状、 工作原理、 制作方式将通过图 6及其相应说 明部分得以详述。 在制作该反射镜整体结构过程中， 所述材料的选取、 制 作还包括平面玻璃、 中间粘结层、 平面玻璃镜的选取及制作， 下面将详细 阐述。
该平面玻璃 6可选用钢化、平整的平面玻璃，厚度为 2匪到 5匪之间， 且厚度优选为 3mm。 该中间粘结层 7的材料可选用热熔胶片， 或者热熔胶 片和加固定型物， 或者液态光固化胶（如 UV胶黏剂 ) 和加固定型物， 或 者普通化学粘结剂， 或者普通化学粘结剂和加固定型物。
当该中间粘结层 7为热熔胶片时， 则该中间粘结层可以是乙烯醋酸乙 烯酯共聚物（EVA ) , 且该中间粘结层的熔化温度为 1 20 °C -140 °C。 当该中 间粘结层 7选用的材料为热熔胶片和加固定型物时， 则需要将该加固定型 物布置于该热熔胶片之下。
当该中间粘结层 7选用的材料为液态光固化胶（如 UV胶黏剂 ) 和加 固定型物时， 则需要将该液态光固化胶（如 UV胶黏剂 ) 均匀地涂覆于该 加固定型物上。
当该中间粘结层 7选用的材料为普通化学粘结剂时， 该曲面反射镜的 成型方法有两种。 一种是， 将一层塑料薄膜如 PVC (聚氯乙烯）加热或冷 压粘结于该平面反射镜 8的背面 （具有涂层的一面） ， 并将另一层 PVC加 热粘结于该平面玻璃 6的欲粘结面上； 然后将该两层 PVC通过该普通化学 黏胶进行固定， 干胶后既可以形成该曲面反射镜。 另一种是， 直接将该普 通化学粘结剂涂覆于欲涂覆的双平面玻璃（平面反射镜 8和平面反射镜 6 ) 两面， 然后再将该双平面玻璃曲面压合， 当该普通化学粘结剂固化后， 就 可以形成曲面反射镜。
该平面玻璃镜 8 可选用制镜级镀膜制平整的平面优质浮法平面玻璃 镜， 且材质为钢化玻璃， 厚度为 0. 5mm- 3. 2mm , 厚度优选为 2mm。 并且该 平面玻璃镜 8尺寸需要比该平面玻璃 6尺寸稍小些。
在步骤 520 , 将该平面玻璃 6、 中间粘结层 7、 平面玻璃镜 8与该曲面 支撑装置进行叠合。
具体地， 将该平面玻璃镜 8、 中间粘结层 7、 平面玻璃 6顺次布置于 该曲面支撑装置上， 以使此四者自下而上形成依次叠合的层状。 然后利用 该平面玻璃镜 8的弹性初步压合固定， 使该平面玻璃 6与该平面玻璃镜 8 按照该曲面支撑装置的凸面 （或凹面）压紧布置。 并且该中间粘结层 7的 外形尺寸略大于该平面玻璃 6的尺寸。
在步骤 521 , 釆用机械方式使已初步压合固定的该平面玻璃镜、 中间 粘结层、 平面玻璃， 弯曲变形。 一种机械方式是， 将该曲面支撑装置抽成 真空， 在大气压作用下使该平面玻璃镜、 中间粘结层、平面玻璃弯曲变形。 另一种机械方式是， 直接向该平面玻璃镜、 中间粘结层、 平面玻璃， 弯曲 变形进行加压， 以使其弯曲变形。 在步骤 530 , 釆用加热或紫外光照或常 温自然固化方式对叠合后的该平面玻璃 6、 中间粘结层 7、 平面玻璃镜 8 进行固化压合。
具体地， 当该中间粘结层 7为热熔胶片时， 釆用高压并升温方式， 使 该中间粘结层 7与该平面玻璃镜 8和平面玻璃 6完全粘合并紧密均匀地结 合为一体。 其中， 该热熔胶片的工艺参数为： （1)升温与升压同时进行；
(2)初步加热， 温度由 20 °C到 50 °C , 加热时间为 20分钟； （3)加热温度由 50 °C到 120 °C , 加热时间为 1小时； （4)胶袋内降温至 50 °C； (5)整个加热 过程真空度小于 10000Pa o
当该中间粘结层 7 由液态光固化胶（如 UV胶黏剂） 和加固定型物组 成时， 则釆用紫外灯照射或者户外太阳光照射方式使之固化， 且 1-5分钟 内初步固化， 20-100分钟即可粘结完成。 并且在该紫外灯或太阳光照射过 程中， 真空度小于 10000Pa。 此外， 使用太阳光照射来完成曲面反射镜的 固化， 整体工艺节能且高效。
当该中间粘结层 7 由聚氯乙烯 （PVC ) 等塑料薄膜和普通化学粘胶剂 组成时， 釆用低温或常温自然固化方式， 使中间粘结层 7与该平面玻璃镜
8和平面玻璃 6完全粘结合并紧密均匀地结合为一体。
当该中间粘结层 7为普通粘结剂时。 直接釆用低温或常温自然固化方 式， 使中间粘结层 7与该平面玻璃镜 8和平面玻璃 6完全粘结合并紧密均 匀地结合为一体。
当该中间粘结层 7由普通化学粘胶剂和加固定型物组成时， 釆用低温 或常温自然固化方式， 使中间粘结层 7与该平面玻璃镜 8和平面玻璃 6完 全粘结合并紧密均勾地结合为一体。
需要说明的是， 该曲面反射镜还可釆用机械方式将平面玻璃与平面玻 璃镜压合成曲面， 然后再将布置于两平面镜之间的中间粘结层随该曲面而 固化， 以使三者形成新的曲面整体。 由于两平面镜之间的中间粘结层阻止 了曲面反射镜向平面状态恢复， 从而保持了所需的曲面结构。
在步骤 540 , 对由该平面玻璃 6、 中间粘结层 7、 平面玻璃镜 8固化压 合而形成的整体， 进行修边及检验， 以形成该曲面反射镜 2。
具体地， 首先对该中间粘结层 7周边进行预料裁掉； 然后检查整体是 否存在有气泡， 是否有杂质， 是否存在破碎、 脱胶等问题， 并基于该检查 结果进行相应修缮， 以形成较优质的曲面反射镜。
在步骤 550 , 将该形成的曲面反射镜安装到镜托 1上。
具体地， 使用 T型和 L型压紧件将该曲面反射镜 2固定于镜托 1上， 以保持良好的强度， 并且方便安装到其它系统中。
图 6是根据本发明一个实施例的曲面支撑装置结构示意图。 该曲面支 撑装置 9由基座 1 0以及多个等间距布置的曲面支撑件 1 1组成。 因此， 该 曲面支撑装置 9的制作过程就是， 该基座 1 0、 该曲面支撑件 1 1的制作以 及将该曲面支撑件 1 1安装到该基座 1 0上的过程。
该曲面支撑装置 9用以在该曲面反射镜 2加工过程中支撑该平面玻璃 6和平面玻璃镜 8 , 以使该平面玻璃 6和该平面玻璃镜 8 固定成型为曲面 形状。 因此， 该曲面支撑件 1 1 曲面的曲率及尺寸与该曲面反射镜 2背部 的曲率及尺寸相近； 若考虑该曲面反射镜制成后的回弹量， 则需要该曲面 支撑件 1 1 曲面的曲率比所需曲面反射镜 2的曲率稍大， 且其曲率半径比 所需曲面反射镜 2的曲率半径稍小， 以补偿该曲面反射镜 2制作完成后的 回弹量。
此外， 为了进一步克服并减少该曲面反射镜 2的回弹量， 在中间粘结 层 7的选取过程中，选用加固定型物作为胶层的支撑结构，使该平面玻璃、 平面玻璃镜、 加固定型物和中间粘结层具有一致的参数， 从而保证该曲面 反射镜在工作过程中具有良好的热稳定性能。 并且该加固定型物还会增强 该平面玻璃、 平面玻璃镜、 中间粘结层之间的粘结支撑作用， 提高了曲面 反射镜的稳定性， 延长了产品使用寿命。
本申请人特别指出， 本发明的曲面反射镜结构可以是凹面型结构， 如 抛物面面型、 圓柱面面型或复合抛物面面型， 也可以是凸面型结构。 并且 本发明可以应用于太阳能光伏系统和太阳能光热系统等多个领域。
显而易见， 在不偏离本发明的真实精神和范围的前提下， 在此描述的本 发明可以有许多变化。 因此，所有对于本领域技术人员来说显而易见的改变， 都应包括在本权利要求书所涵盖的范围之内。 本发明所要求保护的范围仅由 所述的权利要求书进行限定
