the inner flame-retardant glue layer adopts butyronitrile glue with better oil resistance and water resistance, one or more than one steel wire braided layer is used as a reinforcing layer, and the middle flame-retardant glue layer and the outer flame-retardant glue layer adopt synthetic glue with better oil resistance and weather aging resistance; the middle flame-retardant layer and the outer flame-retardant layer are synthesized into an adhesive layer: the chloroprene rubber has the largest oxygen index and the smallest volume resistivity, and can prevent oxygen from being supplied in the combustion process, so that an isolation layer is formed between the rubber and oxygen to inhibit combustion; meanwhile, natural rubber and chlorinated polyethylene resin are selected as auxiliary rubber seeds; the synergistic flame retardant effect of two flame retardants of chlorinated stone and antimony oxide trisilicate is better;
nitrile rubbers, sulfur vulcanization systems are generally used. The accelerator is selected from thiazoles and sulfenamides.

the braided layers of the single-layer steel wire braided hose are usually braided according to a balance angle (54 degrees 44'), and the hose with the structure has the advantages of good pressure bearing performance, good bending performance, high material utilization rate and the like; for the rubber hose with a multi-layer woven structure, the wrapping angle of the inner layer framework is usually slightly smaller than the balance angle. While the outer wrap angle is slightly larger than the equilibrium angle, a configuration commonly referred to as the "mating angle": it features that under the condition of bearing internal pressure, the rubber tube can better play the role of skeleton material of each layer. In practice, the design method of the 'optimal angle array' of the steel wire reinforced rubber pipe is adopted. The mechanical nonuniformity of the multilayer reinforced structure is overcome. The design of large angle-changing equal strength of the steel wire braided rubber pipe ensures that the product has low time length change rate in a static pressure test and small swing amplitude in a pulse test; the pulse characteristic of the whole rubber tube also depends on the material of the steel wire used in the structure; the lower the strength of the steel wire, the softer the pipe body; conversely, the higher the strength of the steel wire, the poorer and more brittle the flexibility; the surface treatment of the steel wire is important and can be galvanized, dry drawn or wet drawn copper plated, for the most widespread applications for brass platers, the correct content ratio of the brass components being important for obtaining the best adhesion results with different adhesive systems.
