Description

一种用于粘接三元乙丙橡胶的热熔胶膜
技术领域
本发明涉及热熔胶膜粘接领域，尤其涉及一种用于粘接三元乙丙橡胶(EPDM)的热熔胶膜。
背景技术
三元乙丙橡胶(EPDM)系由乙烯、丙烯单体加入少量非共轭二烯烃聚合而成。其结构的特点是在聚合物分子主链上无不饱和双键，而在支链上引入了不饱和双键。因而具有优良的耐天候性、耐热性、耐臭氧、耐紫外线性以及良好的加工性能和低压缩永久变形，是生产密封条的首选材料。目前，汽车密封条材料绝大部分都是采用EPDM作为主要原料。三元乙丙(EPDM)胶条采用微波硫化工艺一次成型，表面光洁美观，具有良好的弹性和抗压缩变形，耐天候老化、耐臭氧、耐化学作用及较宽的使用温度范围(-50℃～+150℃)等优异性能，已被汽车门窗幕墙等制造业广泛应用。
由于三元乙丙橡胶分子结构缺少活性基团，内聚能低，加上胶料易于喷霜，自粘性和互粘性很差,普通的热熔胶膜很难满足三元乙丙(EPDM)胶条粘接的要求，强度无法达到汽车行业的要求(常态测试180度剥离力大于45N，-40℃24小时低温存放后测试剥离力大于30N以及100℃高温96小时空气循环试验后大于30N，测试方法参照GB/T2790)。
目前汽车密封条通常采用三元乙丙橡胶表面用溶剂清洗以及打磨后用底涂剂打上底涂，然后再用普通热熔胶膜粘接的工艺进行粘接。此工艺使用溶剂胶水，对工人身体不利，对环境不利；而且工艺流线长，工艺复杂，成品率低。
近年来，对于三元乙丙橡胶热熔粘接的研究并不多，专利CN201310674780.3提出了一种用于粘接三元乙丙橡胶的热熔胶膜，该发明热熔胶膜常态测试180度剥离力最大为85N，-40℃24小时低温存放后测试剥离力最大为59N，100℃高温96小时空气循环试验后，剥离力最大为60N。该专利发明三元乙丙橡胶的热熔胶膜(EPDM)为粘接汽车车窗绒布装饰密封条所用，对于车门密封条、装饰条、嵌条和其他密封条的粘接效果一般。
发明内容
本发明目的在于提供一种易于粘接，且粘接强度大，不用溶剂清洗，不用底涂剂处理，在三元乙丙橡胶硫化后高温时直接复合粘接，可以满足车用三元乙丙橡胶密封条的粘接强度要求的热熔胶膜。该发明热熔胶膜优点在于粘接三元乙丙橡胶(EPDM)强度更高，使用工艺简单，更环保，更方便，可以实现三元乙丙橡胶密封条的车用密封粘接要求。
本发明是通过以下过程实现的：
一种用于粘接三元乙丙橡胶的热熔胶膜，该热熔胶胶膜由30-65份聚烯烃类树脂,15-45份增粘树脂，3-12份功能性填料，3-10份固化剂和1-5份的助粘剂，经混炼，螺杆挤出制模成型。
所述的聚烯烃类树脂为非晶态丙烯共聚物APAO、聚烯烃、苯乙烯类TPE、或聚氨酯类TPE中的一种或几种混合。
所述的增粘树脂为天然松香类树脂、C5石油树脂、C9石油树脂、C5/C9石油树脂、α－萜烯树脂、β－萜烯树脂、萜烯酚醛树脂或萜烯酚改性石油树脂的至少一种。
所述的功能性填料为碳酸钙、硅微粉、滑石粉、白碳黑、或轻质白碳黑的至少一种。
所述的功能性固化剂为异氰酸酯、三聚氰胺树脂或密胺树脂的至少一种。
所述的助粘剂为硅烷偶联剂。
将聚烯烃类树脂，增粘树脂，功能填料和助粘剂在混料机内混炼均匀，无需造粒处理，直接将混合料置于螺杆挤出机中，在170-200℃挤出热熔胶膜。
热熔胶膜的厚度为30-200μm。
使用时，胶膜一面复合1.0-2.0mm厚度的亚克力泡棉，另一面在三元乙丙橡胶硫化后高温时直接复合粘接。
本发明热熔胶膜用于粘接三元乙丙橡胶，粘接力强，无需加强处理，即可满足汽车行业标准的粘接剥离力要求；使用方便，使用时三元乙丙橡胶(EPDM)不用溶剂清洗，不用底涂剂处理，在三元乙丙橡胶硫化后高温时直接复合粘接，很好的提高了大规模量产的生产效率。
