Processing technology for sound insulation and thermal insulation material used for engine housing

Abstract

The invention aims to provide a processing technology for a sound insulation and thermal insulation material used for an engine housing. The processing technology comprises the following steps: (1), material preparation, firstly a proper amount of melamine foamed plastic and a PU film are taken for preparation, and then a fire retardant and glue are used for preparing flame retardant glue according to required proportion; (2), the PU film is compounded on the upper surface of the melamine foamed plastic, and the compounded flame retardant glue is used for carrying out processing and compounding on the back side of the melamine foamed plastic by a static laminating machine, so as to improve thermal insulation and sound insulation effects of a film body. A bubble film manufactured by using the processing technology has the advantages of good thermal insulation and sound insulation effects and excellent flame resistance, and can reach A-O standard, and through the water-proof performanceof the surface of the PU film, the using safety is improved.

Description

technical field [0001] The invention relates to the equipment field of auto parts, including the research, development and improvement of the processing and structure of auto parts, and in particular to a process for processing sound insulation and heat insulation materials for engine compartments. Background technique [0002] With the improvement of living standards, the use of automobile products has also gradually increased, especially in the aspect of automobile interior parts. At this stage, people's automobile use is not only for transportation, but has entered the stage of use and enjoyment. The degree of comfort during use, especially when the car is started, the working sound of the engine is generally loud, and it will also generate a lot of heat, but the flame-retardant sponge used at this stage has the problem of low performance indicators, which is unnecessary for the people in the car. The noise pollution will affect the comfort level of the car, and the heat ...

[0002] With the improvement of living standards, the use of automotive products has gradually increased, especially in the aspect of automotive interior parts. At this stage, people's use of cars is not only for transportation, but has entered the stage of enjoyment. For automobiles The comfort level during use, especially when the car is started, the sound of the engine is generally louder, and it will also generate a lot of heat, but the flame-retardant sponge used at this stage has the problem of low index performance, causing unnecessary damage to the occupants of the car. The noise pollution will affect the comfort of the car, and the heat generated will also lead to safety hazards
