Abstract

The invention discloses a flame-retardant rubber fire hose which consists of a flame-retardant rubber layer being composed of the following materials in parts by weight: 100 parts of a butyronitrile rubber-plastic alloy, 3-7.5 parts of zinc oxide, 0.5-2 parts of stearic acid, 15-20 parts of modified nano alumina powder, 3.2-5.6 parts of resorcinol formaldehyde resin, 1-3 parts of methyl-etherified hexamethylol melamine resin, 1-3 parts of microcrystalline wax, 3-8 parts of rubber protecting wax, 10-28 parts of white carbon black, 16-23 parts of antimonous oxide, 10-20 parts of decabromodiphenyl ethane, 30-45 parts of montmorillonite, 28-35 parts of magnesium hydroxide, 0-5 parts of pigment, 10-23 parts of synthesized plant ester, 1-3 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1-2.5 parts of tetramethylthiuram disulfide and 1-3 parts of sulfur. Due to the flame-retardant rubber in the flame-retardant rubber fire hose, a hardened carbon deposition layer can be formed at the high temperature of 630 DEG C or above, so that a fire source can be isolated from air, and normal use of the flame-retardant rubber fire hose can be ensured.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a flame-retardant fire hose. Background technique [0002] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. The fire hose is mainly composed of inner and outer rubber layers and intermediate fiber fabric layers. At present, after the fire hose encounters an open flame or high temperature, after the rubber is destroyed, the fabric is also destroyed soon and loses its usability. It is a common technical pursuit in the industry to improve the existing fire hose so that the hose has excellent high temperature resistance and can play a better role in fire fighting operations. Contents of the invention [0003] The object of the present invention is to provide a fire hose, the flame-retardant rubber layer on the outside of which can be hardened to form a carbon deposit layer to insulate the fire source and heat so as to pr...
