Material formula of sea water pump rubber impeller

Abstract

The invention provides a material formula of a sea water pump rubber impeller. The material formula of the sea water pump rubber impeller comprises the following components in parts by weight: 50 to 70 parts of isoprene rubber, 20 to 30 parts of chlorosulfonated polyethylene rubber, 10 to 18 parts of carbon black, 10 to 15 parts of magnesium stearate, 5 to 10 parts of a phthalocyanine compound, 3to 5 parts of conductive carbon black, 1 to 2 parts of sulfur, 5 to 10 parts of polyvinyl chloride, 1 to 3 parts of ammonium phosphate, 1 to 5 parts of stearic acid, and 2 to 5 parts of silica. In thematerial formula of the sea water pump rubber impeller, wherein isoprene rubber is used as a main material, wherein chlorosulfonated polyethylene rubber, carbon black, magnesium stearate, the phthalocyanine compound, conductive carbon black and sulfur are added, and the rubber material with high flex fatigue resistance and high peeling resistance is prepared to make the rubber impeller of the seawater pump resistant to flexing fatigue and peeling.

Description

technical field [0001] The invention belongs to the technical field of seawater pumps, and in particular relates to a material formula for a rubber impeller of a seawater pump. Background technique [0002] The seawater pump is a rotor-type water pump used to extract seawater to cool marine diesel engines. The rubber impeller of the seawater pump is made of rubber materials. High flex fatigue resistance and anti-peeling performance from the metal skeleton. Under the standard test of flex cracking ≥ 100,000 times, the seawater pump rubber impeller made of rubber materials in the prior art has a test result of 60,000 flex cracks. The phenomenon of fatigue damage and peeling from the metal skeleton appeared at the second time. Therefore, the seawater pump rubber impeller made of rubber material in the prior art has the problems and deficiencies of flex fatigue resistance and peeling resistance that are difficult to meet the standards.
