Description

一种减振结构橡胶的制备工艺
技术领域
本发明属于减振橡胶加工工艺工序技术领域，具体地说，本发明涉及一种减振结构橡胶的制备工艺。
背景技术
随着现在社会经济的发展，人民生活水平的提高，人们对产品的使用性能提出了更高的要求，减振橡胶在机械等行业中起到举足轻重的重要地位，人们用它来衰减振动、填充空腔等，但是目前的减振橡胶的结构单一，减振效果具有局限性，受到过大的冲击载荷结构很容易被破坏，主要是传统的橡胶制造工艺单一，人们只是单单的停留在，在改善橡胶的各种化学成分的配比上来改善橡胶的力学性能，近些年也慢慢的提出，在制备橡胶的过程中，改变橡胶的形状，通过改变橡胶的结构，来改善它的力学性能，但是也只是局限于橡胶的本体上，满足不了有些大载荷的应用场合。
发明内容
本发明提供一种减振结构橡胶的制备工艺，目的是改善减振结构橡胶的力学性能，扩大其应用范围。
为了实现上述目的，本发明采取的技术方案为：一种减振结构橡胶的制备工艺，包括制胶制胚、结构机加工、嵌入弹簧和合胚，所述制胶制胚。
优选的，首先将固态的合成戊二烯橡胶，丁苯橡胶升温至105摄氏度进行熔胶，然后将熔化的合成戊二烯橡胶和丁苯橡胶的橡胶混合物浇灌入已经预热的胚模一中，且胚模一的预热温度高于熔胶温度，保温10-20分钟，然后逐渐降低胚模一的温度，直到橡胶混合物凝结成型，去除冷却；其次将固态的乙丙橡胶、氯磺化聚乙烯升温至120摄氏度进行熔胶，然后将熔化的乙丙橡胶和氯磺化聚乙烯的橡胶混合物浇灌入已经预热的胚模二中，且胚模二的预热温度高于熔胶温度，保温35-45分钟，然后逐渐降低胚模二的温度到60摄氏度，保证乙丙橡胶和氯磺化聚乙烯的橡胶混合物处于半凝结状态。
优选的，所述结构机加工，对上述步骤由胚模一获得的冷却过后的合成戊二烯橡胶和丁苯橡胶的橡胶混合物，在钻床上钻孔，然后在车床上对孔进行车螺旋。
优选的，所述嵌入弹簧是将圆柱螺旋弹簧通过孔中的螺旋逐渐嵌入由合成戊二烯橡胶，丁苯橡胶混合制成的橡胶中。
优选的，所述合胚是将已经嵌入弹簧的橡胶移入合模的中腔，将制胶制胚获得的半凝结状态的橡胶移入已经预热到60摄氏度的合模的上腔和下腔中，然后将上腔、中腔和下腔合并，然后给上腔和下腔加热，相对施加压力，使其上腔、下腔和一起和中腔合并。
本发明是通过将橡胶这种柔性元件和弹簧这种刚性元件通过制备工艺进行组合，从而改善减振结构橡胶的力学性能，为解决上述问题，对减振结构橡胶做了全新的设计，采用以上技术方案的有益效果是：通过合成戊二烯橡胶和丁苯橡胶合成的橡胶，弹性和连续性好，减振效果好，通过乙丙橡胶和氯磺化聚乙烯合成的橡胶，属于塑料橡胶系列，质地硬，结构强度大；另外在合成戊二烯橡胶和丁苯橡胶合成的橡胶中机加工进行钻孔、车螺旋，然后将圆柱螺旋顺着螺旋拧入孔中，很好的起到当橡胶受到过载的冲击作用时，内部的圆柱螺旋弹簧可以起到抗载荷作用，避免橡胶的结构被破坏，同时由于圆柱螺旋弹簧是螺旋拧入的，所以在橡胶正常工作时，不会因为圆柱螺旋弹簧在孔中跳动产生噪声。
