TPE material applied to fire hose

Abstract

The invention relates to the technical field of rubber materials, and discloses a TPE material applied to a fire hose, which comprises the following substances in percentage by mass: 35-48% of hydrogenated styrene-isoprene-styrene block copolymer, 20-30% of hydrogenated linear hydrocarbon oil, 10-20% of high temperature resistant polypropylene, 5-10% of a polyolefin elastomer, and 0.1-0.2% of an antioxidant. The TPE material disclosed by the invention has excellent high-temperature resistance, and the TPE material disclosed by the invention cannot be aged to cause damage in the processing process of the fire hose under 120 DEG C steam, so that the feasibility of the TPE material applied to the field of the fire hose is improved; moreover, the specific gravity of the TPE material is only 0.89, so that the ultra-light weight performance of the material is guaranteed, and the weight of the TPE material is 30-60% lighter than that of all other types of materials in the market.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a TPE material used in fire hoses. 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. There are three main types of rubber materials used for the lining of traditional fire hoses, natural rubber, ethylene propylene rubber, and polyurethane rubber. These rubber materials generally have the disadvantage of poor high temperature resistance, and are prone to aging and damage in high temperature environments. [0003] In order to ensure that the fire hose can withstand higher pressure, the rubber layer needs to be thicker, and the existing rubber material has a higher density, which greatly increases the weight of the fire hose, making it difficult for firefighters to carry the fire hose.
