The utility model relates to a rubber tube structure, which comprises a rubber tube body, two poly-p-xylene layers, which are respectively formed on the outer surface and the inner surface of the rubber tube body by the vacuum stress-free coating process, so that the outer surface and the inner surface of the rubber tube body can be vacuum stress-free coated to form the poly-p-xylene layer, so as to enhance the anti sticking of the rubber tube body. uff08 Including biological adhesion) and chemical resistance, which can greatly improve the applicability and practicability of rubber tube products.一種膠管結構，其包含一膠管本體；兩個聚對二甲苯層，該兩個聚對二甲苯層係以真空無應力鍍膜製程分別形成於該膠管本體之外表面及內表面；藉此，該膠管本體的外表面及內表面上可以真空無應力鍍膜方式形成該聚對二甲苯層，從而可提升該膠管本體之防沾黏(包含生物沾黏)及抗化學侵蝕等特性，進而可大幅提升膠管產品之適用範圍與實用性。
