High-temperature-resistant anti-corrosion air inlet manifold sealing ring material

Abstract

The invention discloses a high-temperature-resistant anti-corrosion air inlet manifold sealing ring material. The material is prepared from the following raw materials: polyaryl ether nitrile, china stone powder, fluoroether rubber, a flame retardant, polyphosphazene, a surfactant, a plasticizer, a catalyst, a vulcanization accelerator, a vulcanizing agent, a stabilizer, xanthorrhoea australis gum, tung oil calcium rosinate, tremolite asbestos, barium sulfate, serpentine powder, nano zinc oxide, konjac glucomannan and phthalocyanine resin. The high-temperature-resistant anti-corrosion air inlet manifold sealing ring material is prepared by taking the polyaryl ether nitrile and a fluorine ether rubber matrix as main raw materials, rubber and plastic blending is adopted, and auxiliary raw materials such as the tremolite asbestos, the barium sulfate, the serpentine powder, a cross-linking agent, a coupling agent and the like are added, so that the prepared air inlet manifold sealing ringmaterial has composite functions such as flame retardancy, high-temperature resistance, corrosion resistance and the like, production cost is saved, and the material can be popularized and used in a large scale.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-temperature-resistant and anti-corrosion intake manifold sealing ring material. Background technique [0002] For carburetor or throttle body injection (single point injection) engines, the intake manifold is the intake pipe between the carburetor or throttle body and the cylinder head. For multi-point injection engines or diesel engines, the intake manifold refers to the intake pipe after the intake manifold and before the intake port of the cylinder head. The function of the intake manifold is to evenly distribute the air or air-fuel mixture to the individual cylinders. For carburetor or throttle body injection (single point injection) engines, the intake manifold is the intake pipe between the carburetor or throttle body and the cylinder head. For multi-point injection engines or diesel engines, the intake manifold refers to the intake pipe after...

AI Technical Summary

Problems solved by technology

Improper sealing caused by the deformation of the intake manifold will cause unstable engine idling, engine shaking, and weak engine acceleration. Normal Symptoms

All intake manifold gaskets and mounting surfaces must have a good seal to prevent puff air from leaking into the intake manifold, which would result in a lean mixture of puff air and fuel, unstable idle speed, and reduced engine speed at low speeds performance
