具体实施方式
下面结合附图和具体实施例对本发明进一步说明。
实施例一
结合图1对实施例作详细说明，本实施例所涉及的一种全遮光帘复合面料的生产方法，所提到的全遮光帘复合面料包括第一基布层1、TPU黑遮光膜2和第二基布层3。第一基布层1与遮光膜2通过第一胶粘层4相复合，第二基布层3与TPU黑遮光膜2通过第二胶粘层5相复合。第一基布层1和第二基布层2表面均具有压花所形成的花纹。
全遮光帘复合面料是按如下步骤生产：(一)基布的处理、(二)TPU黑遮光膜的制备、(三)第一步热压复合、(四)第二步热压复合。
在步骤(一)基布的处理中，对第一基布层(1)和第二基布层(3)所选择的面料进行预处理。处理是指对第一基布层和第二基布层所选择的面料进行去油去污或退浆等处理，使得面料上不具有其他的油污或其他影响热压复合的 杂质，进而对与TPU黑遮光膜的复合产生影响，使得面料与黑白遮光膜的粘结强度降低，影响遮光帘的使用寿命。
在本发明所涉及的第一基布层和第二基布层所选择的面料，不作特殊要求，常规市场上所出售的面料均可，纯涤面料、纯棉面料或涤棉混纺面料，以及其他材质所制备的面料均可。为了说明本发明，在在本实施例中所使用的是从市场上所购买的纯涤纶的染色布，克重为120克每平方米。并将从市场上所购买的涤纶布在加入了去油剂的清水中进行水洗，水洗温度为50℃。也可从市场上购买经过清洗的面料。
在步骤(二)TPU黑遮光膜的制备中，是将30份的聚氨酯、8份的低密度聚乙烯，20质量份的炭黑、30质量份的乳白剂、8质量份的二氧化钛、10份的纳米明胶微珠、5份的水杨酸苯酯混合均匀，再经过挤压吹塑而成。所得到的份为质量份。所使用的纳米明胶微珠即纳米明胶微球，其粒径为150纳米。
制备黑白遮光膜可以采用压延法、流涎法以及挤出法。采用挤出机又可以采用吹塑法和用狭缝机头直接挤出两种方法，在本实施例中采用挤出吹塑法进行生产黑白遮光膜。
挤压吹塑即挤出吹塑，此种方法是将物料加入至挤出机的机筒后，经螺杆的转动、挤压和搅拌，物料在一定温度作用下熔融塑化，并在螺杆推动下，经过滤网、分流板后通过机头环形口膜间隙挤出成薄壁管，然后在流动状态下趁热用压缩空气将其吹胀，再经风环冷却定型，进入人字板后夹平，由导辊压紧牵引入卷取辊，最后制得薄膜制品。
在本实施例中，由于组份包括了聚氨酯、低密度聚乙烯等材质，控制熔融后的熔体流动速度(MFR)在0.8g/10min，若MFR越小，则加工困难；MFR 越大，则容易引起下垂。并且在进行吹塑前需要对所用到的固态物质进行干燥。在保证挤出坯的光滑的情况下，尽可能的采用较低的加工温度，在本实施例中采用170℃。为了保证挤出坯紧贴模腔壁而得到所需要开关的产品，吹塑压力一般控制在0.5MPa。对于容积大、壁较薄的和MFR较低的树脂，吹塑压力要高此，反之则相反。并且本实施例中的吹胀比采用2，可保证较为合适的膜厚。
所使用的挤出机的基本参数中，模口间隙为1mm，模口直径为250mm，风环直径为500mm，牵引驱动功率为0.4KW，牵引(卷取)速度为2-20m/min；牵引辊筒长度为1100mm，牵引辊直径为150mm，牵引辊中心高为4500mm，人字板长度为1500mm，吹膜最大折径为1000mm，螺杆直径为90mm，螺杆的压缩比为3-4，所制备的TPU黑遮光膜的厚度在0.04-0.1mm。在本实施例中所制务的TPU黑遮光膜的面密度为40-50克每平方米，具体为45克每平方米。
在步骤(三)第一步热压复合：采用热压复合设备在第一基布层(1)的一侧涂覆丙烯酸树脂作为第一粘合层(4)，再在180℃条件下，进行热压将TPU黑遮光膜与第一基布层(1)热压复合；在热压复合的同时进行压花处理，在第一基布层(1)的表面形成设定的图案。复合速度为1800米每小时。所使用丙烯酸树脂为纯丙烯酸脂，其涂覆量为7克每平方米。在进行热压复合时，压力为6kg。
(四)、第二步热压复合：采用热压复合设备在第二基布层(3)的表面涂覆丙烯酸树脂作为第二粘合层，再在180℃条件下，进行热压将上一步骤所制备的复合面料的TPU黑遮光膜一侧与第二基布层(3)热压复合；在热压复合的同时进行压花处理，在第二基布层(3)的表面形成设定的图案。复合速度为1800米每小时。所使用丙烯酸树脂为纯丙烯酸脂，其涂覆量为10克每平方米。在进 行热压复合时，压力为8kg。

对第一基布层和第二基布层的处理与实施例一相同，进行去油去污或退浆等处理，使得基布上不具有其他的油污或其他影响热压复合的杂质，进而对与黑白遮光膜的复合产生影响，使得基布与黑白遮光膜的粘结强度降低，影响遮光帘的使用寿命。
在步骤(二)TPU黑遮光膜的制备中，是将40份的聚氨酯、10份的低密度聚乙烯，20质量份的炭黑、40质量份的乳白剂、8质量份的二氧化钛、15份的纳米明胶微珠、7份的水杨酸苯酯混合均匀，再经过挤压吹塑而成。所得到的份为质量份。
在本实施例中，由于组份包括了聚氨酯、低密度聚乙烯等材质，控制熔融后的熔体流动速度(MFR)在1g/10min，若MFR越小，则加工困难；MFR越大，则容易引起下垂。并且在进行吹塑前需要对所用到的固态物质进行干燥。在保证挤出坯的光滑的情况下，尽可能的采用较低的加工温度，在本实施例中采用175℃。为了保证挤出坯紧贴模腔壁而得到所需要开关的产品，吹塑压力一般控制在0.6MPa。对于容积大、壁较薄的和MFR较低的树脂，吹塑压力要高此，反之则相反。并且本实施例中的吹胀比采用2.5，可保证较为合适的膜厚。
所使用的挤出机的基本参数中，模口间隙为1.2mm，模口直径为350mm，风环直径为650mm，牵引驱动功率为0.8KW，牵引(卷取)速度为2-20m/min； 牵引辊筒长度为1100mm，牵引辊直径为150mm，牵引辊中心高为6500mm，人字板长度为1700mm，吹膜最大折径为1500mm，螺杆直径为120mm，螺杆的压缩比为3-4，所制备的黑白遮光膜的厚度在0.04-0.1mm。在本实施例中所制务的TPU黑遮光膜的面密度为40-50克每平方米，具体为40克每平方米。
在步骤(三)第一步热压复合：采用热压复合设备在第一基布层(1)的一侧涂覆丙烯酸树脂作为第一粘合层(4)，再在130℃条件下，进行热压将TPU黑遮光膜与第一基布层(1)热压复合；在热压复合的同时进行压花处理，在第一基布层(1)的表面形成设定的图案。复合速度为2200米每小时。所使用丙烯酸树脂为纯丙烯酸脂，其涂覆量为8克每平方米。在进行热压复合时，压力为6kg。
在步骤(四)、第二步热压复合中，采用热压复合设备在第二基布层(3)的表面涂覆丙烯酸树脂作为第二粘合层，再在130℃条件下，进行热压将上一步骤所制备的复合面料的TPU黑遮光膜一侧与第二基布层(3)热压复合；在热压复合的同时进行压花处理，在第二基布层(3)的表面形成设定的图案。复合速度为2200米每小时。所使用丙烯酸树脂为纯丙烯酸脂，其涂覆量为9克每平方米。在进行热压复合时，压力为8kg。

对实施例一至实施例三、及对比例一、对比例二所制备全遮光帘进行遮光性、防紫外性能、隔音和隔热性测试。
遮光率的测试是采用符合国际照明委员会要求的美国AATCC-148-79《窗帘材料遮光效应评定方法》，采取光透射的“箱法”来判断窗帘织物的遮光性能。
采用测试纺织品紫外线防护指数UPF来评价纺织品、以及经过10次洗涤和25次洗涤后的紫外线防护效果。经测试，实施例一至实施例三、对比例一、对比例二的UPF值分别为42.6、41.3、43.5、33.6、19.4，洗涤10次后实施例一至实施例三、对比例一、对比例二的UPF值分别为39.7、38.4、40.6、30.4、18.3，洗涤25次后实施例一至实施例三、对比例一及对比例二的UPF值分别为37.2、36.1、38.7、29.5、13.4。由此可知，实施例一至实施例三所涉及的窗帘与对比例相比较，其具有较好的防紫外效果，并且在经过10次和25次洗涤后，其防紫外效果下降不多。
实施例一至实施例三的透光率为0％，即遮光率均为100％。对比例一的透 光率为2％，即遮光率为98％。对比例二的透光率为10％，即遮光率为90％。
为了验证该织物的隔音效果，还进行了简单的隔音性能测试。将一台木工用的微型空气压缩机放在一空房间门口正前方1.6米处，用声级计在房间内，离门0.5米，高为0.4米处测量。然后分别测试开门，用实施例一至实施例三以及对比例一、对比例二所涉及的遮光帘封闭门框，测试这种状态下的噪声。具体结果如下：背景噪声为30.3dB；开门为72.5dB；用实施例一封闭门框：40.6dB；用实施例二封闭门框：40.2dB；用实施例三封闭门框：39.5dB；用对比例一封闭门框：56.2dB，用对比例二封闭门框：61.7dB。这表明该实施例一至实施例三所制备的窗帘具有明显的隔音效果。
通过测试实施例一至实施例三、以及对比例一、对比例二所涉及的复合面料的克罗值，来对面料的隔热性能进行测试。克罗值是描述服装或织物隔热保暖性能即“热阻”的工程单位。在室温20℃或21℃时，相对湿度不超过50％，空气流速不超过10cm/s(相当于有通风设备的室内正常气流速度)的环境中，一个人静坐或从事轻度脑力劳动保持舒适状态时所穿服装的隔热值为1clo，用法定计量单位定义为1clo＝4.30×10 -2K·m 2·h/J＝155m 2·K/W。克罗值的大小表示了织物保暖隔热程度的高低。克罗值越大，面料的导热性越差，其隔热性越好。经测试，实施例一至实施例三、对比例的克罗值分别为0.85、0.83、0.89、0.69、0.42。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范 围内。
