LAMINATED RUBBER HOSE AND MANUFACTURING METHOD THEREFOR

To provide a method for manufacturing a laminated rubber hose making it possible to maintain adhesive force between rubber layers without using a volatile organic compound.SOLUTION: There is provided a method for manufacturing a laminated rubber hose including a first layer 1 and a second layer 2 laminated on an external surface of the first layer 1. The first layer 1 includes not more than 4.5 mass parts of a thermosetting resin with respect to 100 mass parts of a rubber composition. The method includes a lamination step of laminating the second layer 2 on the external surface of the first layer 1 in a state where the external surface of the first layer 1 is maintained in a temperature range of not less than 65°C nor more than 105°C.SELECTED DRAWING: Figure 1 【課題】揮発性有機化合物を用いることなくゴム層間の接着力を維持させることが可能な積層ゴムホースの製造方法の提供。【解決手段】第１層１と、第１層１の外表面に積層された第２層２とを備えた積層ゴムホースの製造方法であって、第１層１は、ゴム成分１００質量部に対して４．５質量部以下の熱硬化性樹脂を含有し、第１層１の外表面を６５℃以上１０５℃以下の温度範囲に維持した状態で第１層１の外表面に第２層２を積層形成する積層工程を備える積層ゴムホースＨの製造方法。【選択図】図１
