Description

一种抗扭曲高压胶管
技术领域
本发明涉及高压胶管技术领域，尤其涉及一种抗扭曲高压胶管。
背景技术
随着中国经济的发展，客户对液压胶管的品质要求不断提升。为保障液压胶管的使用强度，通常采用钢丝来作为增强层。根据钢丝制作方法的不同，液压胶管可分为钢丝编织胶管及钢丝缠绕胶管。而采用钢丝缠绕的工艺制作，将使胶管产品的爆破性能要远优于编织胶管。然而现有的钢丝缠绕管受内胶硬度和缠绕结构的影响，管体笨重坚硬，曲挠性较差，不适宜狭小空间的使用。尤其是高压胶管在使用过程中，收到扭曲之后产生破裂会对生产造成较大的影响。
发明内容
本发明针对现有技术中高压胶管抗扭曲能力不足的缺点，提供了一种抗扭曲高压胶管。
为了解决上述技术问题，本发明通过下述技术方案得以解决：
一种抗扭曲高压胶管，包括内胶层和外胶层，所述的内胶层和外胶层之间还设有若干层中胶层，所述的中胶层至少两层，所述的中胶层之间设有修补层，所述的修补层由复合材料、修补剂和催化剂组成。
作为优选，所述的修补层的复合材料为环氧酯，所述的修补剂为用微囊密封的双环戊二烯，所述的催化剂为格拉布催化剂。
作为优选，所述的内胶层的外侧和外胶层的内侧设有钢丝增强层。
作为优选，所述的内胶层和外胶层均为增加了炭黑的丁晴橡胶。
本发明由于采用了以上技术方案，具有显著的技术效果：在内胶层之间增加了修补层，当胶管在收到扭曲或挤压的破坏时，修补层能够在一定的限度内识别损害的出现，并对裂缝进行自我修补；大大延长胶管的使用寿命，避免胶管破裂产生危害。
附图说明
图1是本发明的结构示意图。
附图中各数字标号所指代的部位名称如下：1—内胶层、2—外胶层、3—中胶层、4—修补层、5—钢丝增强层。
具体实施方式
下面结合附图对本发明作进一步详细描述。
一种抗扭曲高压胶管，如图所示，包括内胶层1和外胶层2，所述的内胶层1和外胶层2之间还设有若干层中胶层3，所述的中胶层3至少两层，所述的中胶层之间设有修补层4，所述的修补层4由复合材料、修补剂和催化剂组成；所述的修补层4的复合材料为环氧酯，所述的修补剂为用微囊密封的双环戊二烯，所述的催化剂为格拉布催化剂。所述的内胶层1的外侧和外胶层2的内侧设有钢丝增强,5，增加其强度，耐扭曲能力强；所述的内胶层1和外胶层2均为增加了炭黑的丁晴橡胶，使其具有良好的柔软性和耐久性。
在内胶层之间还增加了一层修补层4，出现细微的裂缝之后，修补层就可以在一定限度内自我识别，在修补剂和催化剂的作用下，复合材料能够进行自我修补，避免裂口进一步扩大，延长使用寿命。
总之，以上所述仅为本发明的较佳实施例，凡依本发明申请专利范围所作的均等变化与修饰，皆应属本发明专利的涵盖范围。
