Abstract

The invention relates to a water hose for firefighting and a preparation method thereof. The water hose for the firefighting comprises a cylindrical weaving layer at the outer layer and a rubber liner, wherein the rubber liner is prepared by the following raw materials: polyvinyl chloride, acrylic rubber, a compound stabilizer, titanium oxide powder, paraffin wax, white carbon black, an activator, light calcium carbonate, a plasticizer, a binder, a vulcanizing agent and an antioxidant. The water hose for firefighting, provided by the invention, has the advantages that: the high temperature resistance and high pressure resistance are achieved; the adhesive strength of the liner and the outer weaving layer is high so that the liner and the outer weaving layer are not easy to strip, aging resistance is provided; and the service life is long.

Description

technical field [0001] The invention relates to a fire hose and a preparation method thereof. Background technique [0002] With the awakening of people's safety awareness in daily life and the increase of safety accidents, fire fighting equipment is becoming more and more popular. Among them, the fire hose is a kind of hose used in fire fighting equipment to transport water or foam mixture for fire extinguishing. It uses high-strength synthetic fiber as the outer braided layer and rubber as the inner lining. Its performance is mainly determined by the rubber inner lining. . At present, there are mainly three kinds of materials for the rubber lining, natural rubber, ethylene propylene rubber and polyurethane rubber, each of which has advantages, but also has some shortcomings. Therefore, research and development a kind of corrosion-resistant, wear-resistant, high pressure-resistant, aging-resistant fire hose could adapt to the demand of the market.
