Polypropylene through toughening, filling, strengthening, blending and other modified bs can be different properties of the material, in the car
The modified polypropylene material has been widely used.
This article describes the use of polypropylene materials in typical parts of the interior.
1 dashboards Currently used dashboards can be divided into hard dashboards and semi-rigid dashboards.
In the high-end cars more semi-rigid dashboard. As a semi-rigid dashboard skeleton and duct material, different models, different designs can have a variety of materials to choose, long glass fiber 20% reinforced polypropylene PPLGF20 because of its good rigidity should be a very good choice.
Most of the middle and low stalls using hard dashboard. Hard dashboard is composed of two parts, can be divided into dashboard body, dashboard body and skeleton of the three parts. As the PP / EPDM-T20 has good toughness and a certain degree of rigidity, so the instrument board and the lower body of the first choice of materials. Of course, dashboard material can also be used PP / EPDM.T10 or PP / EPDM-T15.
Glove box outside the board material can also be used PP / EPDM.T20, the inner plate material can be used PP-T20 or PP-T30.
The materials available for the door material are PP / EPDM.T10, PP / EPDM.T15, PP / EPDM-T20.
Above only talk about the automotive interior in the polypropylene material in some typical parts on the application, there are many other parts used in the interior of polypropylene materials, such as PP-GF20 or PP-GF30 and so on. The typical application mentioned above is only an example, of course, can also use other types of polypropylene material.
Talked so much PP in the interior of the classic application, then the interior of the car for the requirements of PP material which? We look at.
Second, the interior parts with PP material requirements
Polypropylene through a variety of modification, the perbance of compleby different materials to meet the perbance requirements of various parts. With the car gradually into people's daily life, it is getting closer and closer, more and more, both from the visual, tactile or smell, people have more and more demanding. In order to create a more comfortable, beautiful car interior environment, this article as the interior material PP put forward some other requirements.
Note: Each part is required to have different mechanical properties due to its different use b, different load levels, and different functions. The same material is applied to different parts. For example, the same PP / EPDM.T20 applied to different parts, the bending modulus and impact toughness will have compleby different requirements. Therefore, this paper does not describe the mechanical properties of the material.
1 scratch resistance requirements
Car interior parts of the raw material PP is relatively high hardness, so the user's use of the process, some parts are easy to be scratched, scratched or kicked, over time, parts of the surface was pale, very ugly. So the PP material must have scratch-resistant properties.
Specific requirements:
Under the b of a certain load, with the provisions of the knife, the vertical cross in the sample surface of the 20 strokes, and then buate the brightness of the b changes. Usually requires no change in brightness of more than 1.5, that is △ L ≤ 1.5. Commonly used loads are 5N and 10N, depending on the part of the use of parts or paint to choose a different load.
2 anti-white mark perbance
PP material of the decorative parts in the assembly or by bending, shock and other external forces, often appear white phenomenon, and with the passage of time, white marks will be further expanded, affecting the beauty of the interior. This is what we usually say that the phenomenon of stress whitening. In order to avoid stress whitening, PP material must also have anti-stress whitening perbance.
Specific requirements:
At a certain height, the sample is subjected to a falling ball impact test, and then the brightness change is buated and recorded. After a period of time, once again buate the impact of the impact of changes in parts; and then the sample stored at high temperature, after a specified time to re-buate the sample brightness changes.
3 heat aging perbance
Polypropylene material due to its own structure, it is easy to be oxygen in the air oxidation, especially by the role of light and heat, it will accelerate aging, and thus destroyed its physical and mechanical properties. Affecting the life of the parts. So PP material must have the perbance of heat and oxygen aging. As an interior parts, at least to meet the conditions of 150 ℃ 400 hours without powder phenomenon. Experiments can be done with the entire part, or by cutting the part into a spline and in a dry box.
4 distribution perbance
People on the car interior air quality requirements are getting higher and higher, the state immediaby to the introduction of automotive interior air quality requirements and other relevant standards. So in order to ensure a good car interior environment, as an interior parts, without exception, must meet the four requirements of the distribution perbance. Interior parts distribution perbance, including odor test, baldehyde content determination, condensation components, total carbon emissions.
