Vehicle interior decoration material VOC removal master batch and preparation method thereof

Abstract

The invention discloses a vehicle interior decoration material VOC removal master batch and a preparation method thereof, and belongs to the technical field of materials. The vehicle interior decoration material VOC removal master batch comprises, by weight, 10-30 parts of polyacrylamide, 10-20 parts of polyvinyl alcohol, 40-80 parts of a VOC remover, 5-30 parts of polyolefin, 0-20 parts of ABS resin, 5-10 parts of a compatibilizer and 0.3-1.0 part of an assistant. The invention also discloses a preparation method of the vehicle interior decoration material VOC removal master batch. The masterbatch uses the VOC volatile matter remover as a main component, the VOC volatile matter remover interacts with VOC volatile components in the interior decoration in the processing process to extractthe volatile components from a polymer melt, and the volatile components are removed by using vacuum negative pressure, so the content of the VOC volatile components in the vehicle interior decorationmaterial is effectively reduced, and the air quality in the vehicle is improved.

Description

technical field [0001] The invention relates to a masterbatch material for vehicles and a preparation method thereof, in particular to a VOC-removing masterbatch for vehicle interior materials and a preparation method thereof, belonging to the field of material technology. Background technique [0002] As consumers continue to increase their requirements for car comfort and safety, the air quality in cars has increasingly become one of the main indicators for people to choose cars. At present, professional organizations such as automobile associations in various countries have formulated relevant standards and requirements to limit the air quality in vehicles, and world-renowned automobile companies have formulated their own corporate standards to control the air quality in vehicles. Volatile Organic Compounds (Volatile Organic Compounds, referred to as "VOC") is an important reason that affects the air quality in the car. VOC mainly includes alkanes, olefins, aromatics, al...

Problems solved by technology

[0006] 3. Add raw material post-processing equipment, such as baking, etc. This scheme can realize the removal of volatile matter, but the energy consumption is very large, and the efficiency is low, and it will also cause unevenness

However, the air stripping agent of this method still relies on weak physical adsorption to combine with porous material carriers, and cannot be stored for a long time and transported over long distances, especially when heated, the effective air stripping agent components are seriously lost, and the VOC improvement effect is significantly reduced , or even dangerous due to the leakage of the air-lifting agent components, and, in the process of use, when added to the high-temperature twin-screw extruder, the air-lifting agent is easy to gasify, and the loss is serious. It must be processed by a special process, which also poses a threat to the material factory many production problems
