防辐射复合面料及其制造工艺
技术领域
本发明涉及射线辐射防护领域，具体涉及一种防辐射复合面料及其制造工艺。
背景技术
现有的防辐射复合面料的结构包括：基布以及胶合于基布一侧的防辐射膜层。现有的防辐射复合面料的制造工艺为：（1）将防辐射原材料按比例充分搅拌混合得到防辐射混合料；（2）在基布上涂覆胶液，然后将防辐射混合料均匀涂覆在基布上的胶液上，再经过热轧成型，使得基布上形成与基布相胶合的防辐射膜层，从而得到防辐射复合面料。上述制造工艺制得的防辐射复合面料的缺点为：防辐射膜层裸露在外易受损，易撕裂，复合面料整体强度较低，使用寿命较短。
发明内容
本发明所要解决的技术问题是：将提供一种防辐射膜层不易损坏、使用寿命更长的防辐射复合面料及其制造工艺。
为了解决上述问题，本发明所采用的技术方案为：防辐射复合面料，包括：基布以及胶合于基布上的防辐射膜层，其特征在于：在防辐射膜层的表面上复合有能对防辐射膜层进行保护以及增强复合面料强度的防护增强层。
进一步的，前述的防辐射复合面料，其中：防护增强层为PU层。
进一步的，前述的防辐射复合面料，其中：防护增强层的厚度为0.1～0.3mm。
进一步的，前述的防辐射复合面料，其中：防辐射膜层的厚度误差小于0.02mm。
防辐射复合面料的制造工艺，其特征在于：工艺步骤如下：
（1）将防辐射原材料按比例充分搅拌混合得到防辐射混合料；
（2）在输送模板上先涂覆防护增强层，然后在惰性气体保护下并且在防护增强层固化前将防辐射混合料涂覆在防护增强层上，使得在防护增强层上形成防辐射膜层，接着经热轧成型，然后烘干后，使得防护增强层和防辐射膜层复合在一起形成复合层；
（3）将复合层和基布进行胶合，并且使防辐射膜层直接紧贴胶合于基布表面上、而使防护增强层位于防辐射膜层外侧，从而得到防辐射复合面料坯布；
（4）将防辐射复合面料坯布在惰性气体保护下、于180～250℃温度下进行固化成型，从而得到防辐射复合面料成品。
进一步的，前述的防辐射复合面料的制造工艺，其中：复合层的厚度误差小于0.02mm。
进一步的，前述的防辐射复合面料的制造工艺，其中：步骤（4）中，在200℃温度下进行固化成型。
进一步的，前述的防辐射复合面料的制造工艺，其中：防护增强层为PU层。
进一步的，前述的防辐射复合面料的制造工艺，其中：通过出型机来对防护增强层和防辐射膜层进行热轧成型。
进一步的，前述的防辐射复合面料的制造工艺，其中：通过胶合合布机对复合层和基布进行胶合。
本发明的优点为：本发明所述的防辐射复合面料由于在防辐射膜层表面上复合有防护增强层（PU层），使得复合面料的强度大大提高，不易被撕裂，另外，由于防护增强层能对防辐射膜层进行保护，使得防辐射膜层不易损坏，从而延长了防辐射复合面料的使用寿命；所述的制造工艺能使基布、防辐射膜层、防护增强层紧密的复合在一起，不易脱开；在惰性气体保护下涂覆防辐射混合料能大大延缓防辐射混合料的氧化速度，使得防辐射材料的防护效果能长时间保持，从而能进一步延长防辐射复合面料的使用寿命；防辐射复合面料坯布在惰性气体保护下进行固化成型能使胶水的氧化速度大大降低，从而能使胶合的效果更好。
附图说明
图1为本发明所述的防辐射复合面料的层状结构示意图。
具体实施方式
下面结合具体实施例和附图对本发明作进一步的详细描述。
如图1所示，防辐射复合面料，包括：基布1以及胶合于基布1一侧的防辐射膜层2，在防辐射膜层2的表面上复合有能对防辐射膜层2进行保护以及增强复合面料强度的防护增强层3，本实施例中，防护增强层3为PU层，厚度为0.1～0.3mm ，优选为0.2mm，厚度过厚会影响面料制衣后成衣的舒适性，厚度过薄防护增强的作用会不明显。PU层又称聚氨酯树脂层，聚氨酯树脂是一种具有高强度、抗撕裂、耐磨特性好的高分子材料，所以PU层能很好的对防辐射膜层2进行防护，并且能很好的提高面料的整体强度，从而延长了复合面料的使用寿命。
另外，在本实施例中，防辐射膜层2的厚度误差小于0.02mm。厚度误差太大的话会增加防辐射复合面料重量的误差，从而无法准确把控面料重量。
防辐射复合面料的制造工艺，工艺步骤如下：
（1）将防辐射原材料按比例充分搅拌混合得到防辐射混合料；
（2）在输送模板上先均匀涂覆防护增强层3，本实施例中，防护增强层3为PU层；然后在惰性气体保护下并且在防护增强层3固化前将防辐射混合料均匀涂覆在防护增强层3上，使得在防护增强层3上形成防辐射膜层2，在惰性气体保护下涂覆防辐射混合料是为了延缓防辐射混合料的氧化速度，从而能最大程度的保持防辐射材料的防护效果；接着通过输送模板将防护增强层3送入出型机中，经出型机热轧成型，然后烘干后，使得防护增强层3和防辐射膜层2复合在一起形成复合层，复合层的厚度误差小于0.02mm，这样设置也是为了更好的把控面料的重量；
（3）将复合层和基布1送入胶合合布机中进行胶合，并且使防辐射膜层2直接紧贴胶合于基布1表面上、而使防护增强层位于防辐射膜层外侧，从而得到防辐射复合面料坯布；
（4）将防辐射复合面料坯布在惰性气体保护下、于200℃温度下进行固化成型，从而得到防辐射复合面料成品。
