Abstract

The invention belongs to the technical field of fire-fighting equipment, and provides a new material for an inner liner of a fire hose and a preparation method of the material. The material comprises the following raw materials, by weight part, 20-39 parts of a phenolic resin, 16-31 parts of an acrylic resin, 2-7 parts of light calcium carbonate, 3-11 parts of nanometer carbon fiber, 2-6 parts of activated clay waste residue, 5-5 parts of silicon crystal whiskers, 2-5 parts of a fire retardant, 0.3-6 parts of a curing agent, 0.11-4 parts of an anti-aging agent, and 1-3.6 parts of a binder. The fire retardant, binder, and anti-aging agent are added in the formula, and inorganic and organic matters are added at the same time. The materials are prepared according to a reasonable ratio, and the inner liner has high temperature and pressure resistance, aging resistance, and long service life.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a new type of material for the inner lining of a fire-fighting hose and a preparation method thereof. Background technique [0002] The fire hose is a kind of hose used to transport water or foam mixture in fire facilities. The traditional fire hose is lined with rubber and the outer surface is wrapped with flax braid. Advanced fire hoses are made of polymeric materials such as polyurethane. The fire hose uses high-strength synthetic fibers as the base layer, and there is a layer of lining inside. Because the lining is a structural layer that directly contacts the water or foam mixture used for fire extinguishing, the material of the lining directly determines the use of the fire hose. performance. At present, there are mainly three types of rubber materials for the inner lining of fire hoses, natural rubber, ethylene-propylene rubber and polyurethan...
