The invention discloses a cotton-enhanced hydraulic hose. The cotton-enhanced hydraulic hose comprises an oil resistance layer (1), a heat resistance layer (2), a cotton enhancement layer (3) and an outer glue protective layer (4) which are arranged in sequence from inside to outside, wherein the oil resistance layer (1) is made of nitrile rubber, and the thickness of the oil resistance layer is 2mm; the heat resistance layer (2) is made of polyacrylate rubber, and the thickness of the heat resistance layer is 3mm; the cotton enhancement layer (3) is formed by knitting steel wires and cotton, and the thickness of the cotton enhancement layer is 4mm; the outer glue protective layer (4) is made of natural rubber. Through the above manner, the cotton-enhanced hydraulic hose is made of a material with oil resistance and heat resistance and the cotton enhancement layer with good tenacity, and the cotton-enhanced hydraulic hose has the advantages of oil resistance, heat resistance, high tenacity and the like.
