Composite telescopic hose and preparation method thereof

Abstract

A composite telescopic hose and method for preparing the same. The composite telescopic hose includes an inner tube having the following raw materials in parts by weight: 20-50 parts of SEBS; 40-70 parts of a white oil; 3-15 parts of polypropylene; 3-12 parts of ethylene propylene diene monomer; 0.05 to 0.3 parts of an antioxidant; and 0.2-0.8 parts of an ultraviolet absorber. The inner tube of the composite telescopic hose is made of a material which has superior physical properties, high elongation at break and tensile strength, and can maintain structural integrity under extreme conditions, which significantly improve durability and service life of the product, and reduce maintenance cost. A synergistic composite formulation optimizes physical and mechanical properties of the material of the inner tube at a molecular level, achieving a balance between flowability, stability and mechanical properties, thereby ensuring that the hose performs well under various operating conditions.
