The air quality in the car is one of the important assessment indicators. Its performance directly determines the driving experience and health and safety of a car that can bring us. One of the important sources of quality is the internal plastic of the car.
Due to the large types of car plastic, this requires us to clarify the high -end improvement method of plastic interior and find a different level of breakthrough direction. Here we are divided from three levels: \”clean plastic\”, development composite materials, and development in the direction of safety and durability.
Clean plastic The selection of automotive interior materials, except for the overall overall as a whole In addition to the beautiful and generous, the most important thing is how to choose low VOC The material emitted to avoid \”invisible killers\”. For example, the German Automobile Association stipulates that the concentration of formaldehyde in the car must not exceed 0.08ppm . As the name implies, cleaning plastic can refer to materials that are harmless to people and the environment. In this regard, including spray-free plastic, bioplastics, organic ––
The selection of new materials such as inorganic nano composite materials has become an important research direction. Here, the key examples are exempt from spraying plastic.
The coating contains a large number of VOC
, during use, it will send out the toxic and harmful toxic and harmful toxic and harmful toxic, formaldehyde, dyshane, etc. Chemicals seriously affect environmental quality, and the application of spray -free materials is getting more and more due to the less damage to the environment.Views. For example, spray -free materials for metal luster effect ( pp ,
pc/abs , pmma , PA ), can replace electroplating plastic, for interior decorative strips, luggage brackets, etc. Components.
The free spray -free high -gloss without trace plastic as a spray -free green molding technology has attracted much attention. Its characteristics are: the parts are the same material as a whole, which is extremely beneficial to environmental protection and reduction costs. The main highlight -free spray materials are mainly pmma/asa ,
and asa On the interior, they are mainly applied to components and other components of the car console, and there is room for further exploration. Development of composite materials parts of composite materials on the car Mainly instrument panels, door panels, etc., which are basically composed of epidermis (plastic, fabric, leather), sound insulation and vibration reduction part (foam or fiber), and skeleton. Feel comfortable and beautiful. Taking the inside of the door as an example, in order to meet the weather resistance and soft requirements, many companies have begun to use thermoplastic elastic body and pp [ 123] The structure of foam plates is superimposed, and the integrated formation scheme of the inside of the door and the door armrest is used to meet the requirements of comfortable and beauty and improve space in the vehicle.
In addition, composite materials can be developed through modified methods. For example, the gel -based material is evenly scattered in
pp The substrate material, the polymer material particles of gelization have the characteristics of the height of the opposite sex, which improves the slight roughness of the material surface , Powerful reflexing the lighting effect, which is close to the low -gloss effect of the skin. Under the same light source, high -quality interior pp The parts can weaken reflection than ordinary materials, and the gloss is uniform, effectively improving the grade of the interior. Development to safety and durability
Today’s traffic accident rate rate High, the safety requirements of car interior parts are even more prominent. For example, the head shock test on the surface of the instrument panel, the knee impact trial on the lower edgeThe inspection, etc., are required to be tested in the interior that cannot be broken, nor can it splash or cause edges and corners. Therefore, the interior of the car not only requires comfortable and beautiful, but also requires the safety of passengers.
The surface is polymethyl acrylic methyl (
pmma ) The car window glass prepared by the film, when
123] PMMA When the film is impacted by the internal direction of the car into the tension state, it is easy to break here, which can make passengers break the window when they encounter an accident and improve safety performance. In addition to safety, the average service life of automobiles in industrial developed countries is general It is generally longer than developed countries. The average usage of global automobiles is about
15 . Therefore, the durability of interior parts is also an important judgment indicator. In this regard, the use of high -performance engineering plastics is extremely urgent. Foreign car brands are now using high -performance engineering plastics and plastic composite materials. In the future, the door, roof, seat parts, wheels, and car peripherals PIPE EXTRUSION LINE components, and even the body may use engineering plastics.
In the environment of car lightweight and environmental protection, cars The use of plastic parts in the interior is the general trend. With the improvement of living standards, users have become more urgent to high -end cars.
In addition to the traditional art design techniques, there is still room for further in -depth in terms of \”clean plastic\”, development composite materials and safety, durability and other aspects.
