Abstract

The invention relates to a noise reduction and heat insulation pad, which is characterized by comprising an aluminum foil glass fiber cloth, an aerogel heat insulation felt, a high temperature resistant glass fiber cloth and a stainless steel wire mesh which are arranged in sequence from top to bottom. The method for producing the noise reduction and heat insulation pad comprises the following steps of: (1) cutting the aluminum foil glass fiber cloth, the aerogel heat insulation felt, and the high temperature resistant glass fiber cloth into sheets in required dimensions, drying the sheets at the temperature of between 90 and 100 DEG C in a drying oven for 30 to 40 minutes; (2) degreasing the stainless steel wire mesh in a degreasing agent for 45 to 50 minutes, and drying the stainless steel wire mesh at the temperature of between 90 and 100 DEG C in the drying oven for 20 to 30 minutes; and (3) sewing the aluminum foil glass fiber cloth, the aerogel heat insulation felt, the high temperature resistant glass fiber cloth and the stainless steel wire mesh which are treated by the steps together by using metal fiber lines to obtain a finished noise reduction and heat insulation pad. The noise reduction and heat insulation pad has the characteristics of low thermal conductivity, good sound absorption effect and the like, and high temperature heat source and structural noise caused by a high-temperature object can be reduced.

Description

technical field [0001] The invention relates to a noise-reducing heat-insulating pad and a production method thereof, in particular to a noise-reducing heat-insulating pad mainly used on high-temperature objects such as an air outlet device in a high-power engine, an exhaust pipe, a muffler pipe, and a corrugated pipe. The field of environmental protection products that control noise and environmental pollution. Background technique [0002] With the development of science and technology and the ever-changing changes in the construction field, life, and transportation facilities, especially domestic engines are developing towards high speed, light weight, safety, reliability, and comfort, so the noise, vibration, and heat insulation indicators of the facilities have been improved. Many countries in the world have listed these items as important indicators for evaluating the quality of facilities. [0003] Take the exhaust pipe of an automobile engine as an example: under lo...
