Intake manifold resonant cavity adopting flame retardant rubber

Abstract

The invention provides an intake manifold resonant cavity adopting flame retardant rubber. The intake manifold resonant cavity is made of the flame retardant rubber. The flame retardant rubber is prepared from, by weight, 100 parts of chloroprene rubber, 1 part of stearic acid, 6 parts of zinc oxide, 4 parts of magnesium oxide, 0.5 part of an accelerant NA-22, 30 parts of clay, 20 parts of carbon black N774, 15 parts of cycloparaffin and 0-15 parts of aluminum hydroxide. The intake manifold resonant cavity is made of flame retardant rubber and has the good physical and chemical performance, automobile spontaneous combustion is avoided, the reliability of whole equipment is further improved, and the service life of the whole equipment is further prolonged.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an intake manifold resonant cavity. Background technique [0002] In my country, the development of the automobile industry and plastic manufacturing technology is advancing by leaps and bounds. Engine parts made of metal are gradually replaced by engine parts made of plastic represented by the intake manifold. As one of the most critical components of the engine, the intake manifold is used in automobiles. It has been widely used in the industry, and its core function is to provide a fully and uniform mixture for each cylinder of the engine, which is a key factor affecting engine power and fuel consumption. [0003] There are many reasons for the spontaneous combustion of automobiles, which have a lot to do with the plastic parts inside the car. In summer, when the outdoor temperature is 35 degrees, the temperature inside the car can reach 70 degrees. Under the stimulation of electric s...
