Abstract

The invention relates to a method for preparing a lining material of a fire hose and belongs to the technical field of fire fighting. The method comprises the following steps: by taking silicone rubber as a raw material of a lining material, doping the silicon rubber with cerium oxide and an aluminum alloy, and preparing a hydrotalcite-like thin film on the surface of the silicon rubber by using an in-situ growth method, so as to prepare a lining material of a fire hose with good oil resistance and corrosion resistance. The silicone rubber has excellent weather resistance, high and low temperature resistance, electrical insulation, radiation resistance and biological inertia; because of a special electron structure (an f electron layer is underfill) of rare earth cerium, a complex can be easily formed, the formed complex is capable of inhibiting swelling of rubber in a solvent by preventing chain segment movement of rubber molecules, and then the oil resistance of the rubber can be improved; and when the hydrotalcite-like thin film is in contact with a solution, original anions in layers have an exchange reaction with anions in the solution, corrosive ions in layers can be contained in layers, contact of a substrate with the corrosive ions can be inhibited, and thus the purpose of inhibiting corrosion can be achieved.

Description

technical field [0001] The invention relates to a preparation method of a lining material for a fire hose, belonging to the technical field of fire protection. Background technique [0002] In recent years, large-scale cities and high-rise residential buildings in my country are a general development trend. There are more and more high-rise buildings and they are getting taller, so the requirements for fire hoses are becoming more and more stringent. The original fire hose used to convey water has low strength, is prone to damage during use, has a heavy weight per unit length, and has low working pressure. It cannot be supplied with high-pressure water source, and cannot meet the fire fighting requirements of high-rise buildings. [0003] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. The traditional fire hose is generally made of plastic flat yarn, synthetic fiber or yarn, linen braid, etc. according to the warp and we...
