Problems solved by technology

In some colder regions, the turbocharger tube made of AEM often fails to meet the specified technical indicators due to the low-temperature pressure change performance, so that the turbocharger tube cannot meet the requirements, resulting in oil leakage and even the risk of tripping. , so this type of turbocharger pipe has a great safety hazard

Abstract

The invention discloses an ethylene-acrylic elastomer formula for a turbocharged tube. The ethylene-acrylic elastomer is prepared from the following raw materials in parts by weight: 70-90 parts of ethylene-acrylic elastomer, 10-30 parts of methyl vinyl silicone rubber, 1-2 parts of stearic acid SA-200, 30-60 parts of carbon black N550, 1-2 parts of an antioxidant 445, 1-2 parts of microcrystalline wax 654, 4-7 parts of a curing agent DCP, 4-15 parts of a fumed colloidal silica dispersion A200 and 0.1-0.3 part of a coagent TAIC. With the adoption of the ethylene-acrylic elastomer disclosed by the invention, good comprehensive performance can be obtained, the mechanical property is good, the low-temperature voltage violation performance is also remarkably improved; when VMQ / AEM combination ratio is 30 / 70, the low-temperature voltage violation performance is (40 DEG C below zero*22h), is lowered from 95 to 72 in an AEM formula and is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an ethylene acrylate rubber formulation for turbocharger tubes. Background technique [0002] The turbocharger tube is an important part of the turbocharger, and the reliability of the turbocharger tube is directly related to the safe operation of the car. In some colder regions, the turbocharger pipe made of AEM often fails to meet the specified technical indicators due to the low-temperature pressure change performance, so that the turbocharger pipe cannot meet the requirements, resulting in oil leakage and even the risk of tripping. , so this type of turbo tube has a great potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ethylene acrylate rubber formula for turbocharger tubes, which can improve the cold resistance of turbocharger tubes and increase their stability through reasonable match...
