Embodiment 1

[0036] Such as figure 1The shown one is a high-temperature heat-resistant and heat-insulating cover for the exhaust system of an SCR automobile, which is mainly used in the SCR after-treatment system. Since the SCR catalytic converter is a very important part, it not only bears the responsibility of reducing the exhaust gas in the engine. At the same time, it also acts as a muffler, that is, the catalytic converter has the function of integrating the SCR catalytic converter and the exhaust muffler, but it needs to maintain a high temperature in the SCR catalytic converter. If the temperature is too low, it will It affects the effect of catalytic conversion, so it is necessary to wrap the SCR catalytic converter with a heat-resistant heat insulation cover to maintain a higher temperature for the SCR catalytic converter. The high temperature resistant heat insulation cover of the present invention is mainly used to include a housing and a fixing member for fixing the housing. Th...

Embodiment 2

[0038] A kind of heat-resistant and heat-insulating cover for SCR automobile exhaust system, such as figure 1 As shown, the structure is the same as that of Embodiment 1, and a continuous basalt fiber mesh cloth 103, a continuous basalt fiber needle felt 104, glass fiber chopped strands and an adhesive are arranged between the housing inner wall 101 and the housing outer wall 102, and the mass is Percentage, the continuous basalt fiber mesh 103 is set to 8%, the continuous basalt fiber needle felt 104 is set to 81%, the glass fiber chopped yarn is 7%, the adhesive is set to 4%, and the adhesive is set to ring Oxygen resin, the shell is set to aluminum plate, and the thickness is set to 0.2mm. Such a high temperature resistant heat insulation cover is flame retardant, with a heat reflectivity of 93%, a maximum heat-resistant temperature of 880°C, and a thermal conductivity of 0.051 W. / m.k, its heat insulation performance is excellent, which meets the requirements of SCR cataly...

Embodiment 3

[0040] A kind of heat-resistant and heat-insulating cover for SCR automobile exhaust system, such as figure 1 As shown, the structure is the same as that of Embodiment 1, and a continuous basalt fiber mesh cloth 103, a continuous basalt fiber needle felt 104, glass fiber chopped strands and an adhesive are arranged between the housing inner wall 101 and the housing outer wall 102, and the mass is Percentage, continuous basalt fiber mesh 103 is set to 5%, continuous basalt fiber needle felt 104 is set to 87%, glass fiber chopped yarn 5%, adhesive is set to 3%, adhesive is set to epoxy resin, The shell is made of aluminum plate, and the thickness is set to 0.09mm. Such a high-temperature heat-resistant and heat-insulating cover is flame-retardant, with a heat reflectivity of 96%, a maximum heat-resistant temperature of 900°C, and a thermal conductivity of 0.048 W / m.k. Its heat insulation performance is excellent, which meets the requirements of SCR catalytic converter heat prese...

Abstract

The invention discloses a high-temperature-resistant heat-insulation heat preservation cover for an SCR automobile exhaust system and a manufacturing method of the high-temperature-resistant heat-insulation heat preservation cover, and belongs to the technical field of automobile engine exhaust emission. The high-temperature-resistant heat-insulation heat preservation cover comprises a shell and a fixing part used for fixing the shell. A continuous basalt fiber screen cloth, a continuous basalt fiber punched felt, a glass fiber chopped strand and an adhesive are arranged between the inner wall of the shell and the outer wall of the shell. The manufacturing method of the high-temperature-resistant heat-insulation heat preservation cover comprises the steps of manufacturing of continuous basalt fiber, manufacturing of the continuous basalt fiber screen cloth, strand chopping, manufacturing of the continuous basalt fiber punched felt, manufacturing of the shell, pressing and cooling. The continuous basalt fiber is used as the main heat preservation and heat insulation material, the production cost can be reduced, the performance of a heat preservation and heat insulation pipe can be improved, the heat preservation and heat insulation performance of the heat insulation pipe is better, and the high-temperature-resistant heat-insulation heat preservation cover is wide in application range, can be applied to automobiles and motorcycles, and is convenient to assemble and disassemble and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of automobile engine exhaust gas emission, and in particular relates to a high-temperature-resistant heat-insulating heat-preservation cover for an SCR automobile exhaust system and a manufacturing method thereof. Background technique [0002] With the development of society, the penetration rate of automobiles is getting higher and higher. On the one hand, automobiles bring convenience to people, and on the other hand, they also cause great pollution to the environment because of the exhaust emissions of automobiles; Emissions, to solve the problem of environmental pollution, all countries have successively stipulated motor vehicle pollutant emission standards. At present, my country mainly implements the National IV emission standard, which is the fourth phase of the national motor vehicle pollutant emission standard. With the upcoming implementation of the National V standard, automobiles The emission stand...
