Preparation process of odor control agent for automobile high-filling polymer sound insulation plate

Abstract

The invention discloses a preparation process of an odor control agent for an automobile high-filling polymer sound insulation board. The preparation process specifically comprises the following steps: preparing a modified adsorption type deodorant mixture A; preparing a reaction type deodorant mixture B; pouring the obtained adsorption type mixture A, the reaction type deodorant mixture B obtained in the step 2 and a high-dispersion type coupling agent into mixed material production equipment according to a certain mass percent, and carrying out mixed material production; the stirring time of the materials in the mixing production process is not less than 4 hours; according to the odor control agent, 10% of the high-dispersion coupling agent, 60% of the adsorption type odor removal agent mixture A and 30% of the reaction type odor removal agent mixture B are more sufficiently mixed and stirred through material mixing production equipment, the produced odor control agent has excellent physical adsorbability, meanwhile, the odor control agent can chemically react with harmful gas, and therefore the odor control agent has a good odor removal effect. And the harmful gas content of the high-molecular sound insulation plate is reduced to a greater extent.

Description

technical field [0001] The invention relates to the technical field of odor control of auto parts, in particular to a preparation process of an odor control agent for high-filling polymer sound-insulating panels for automobiles. Background technique [0002] With the advancement of automobile manufacturing technology, people pay more and more attention to the control of noise and vibration inside passenger cars. The fatigue of the occupants, and it affects the driving safety of the car. As an important evaluation index for the comfort of the car, the car noise will also reflect the design level and process level of the manufacturer to a large extent, and the polymer sound insulation board of the car is used as One of the important parts of automobile sound insulation, in order to ensure the sound insulation of the production of sound insulation boards, we often start with the materials and processing methods of the boards. [0003] Although the high-filling polymer sound-in...

AI Technical Summary

Problems solved by technology

[0003] Although the high-filling polymer sound-insulating sheet has a good sound-insulating effect, it also has a certain peculiar smell, which makes the voc content inside the car cannot be lower than the specified value after the car is assembled, and the existing odor control agent Due to the limitation of the production process, the odor control agent often produced can only undergo physical adsorption or chemical reaction, its control effect is single, and the deodorization effect is poor
