Polypropylene through toughening, filling, strengthening, blending and other modified methods 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 performance of completely different materials to meet the performance 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 position, 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 completely 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 action of a certain load, with the provisions of the knife, the vertical cross in the sample surface of the 20 strokes, and then evaluate the brightness of the location 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 performance

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 performance.

Specific requirements:

At a certain height, the sample is subjected to a falling ball impact test, and then the brightness change is evaluated and recorded. After a period of time, once again evaluate the impact of the impact of changes in parts; and then the sample stored at high temperature, after a specified time to re-evaluate the sample brightness changes.

3 heat aging performance

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 performance 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 performance

People on the car interior air quality requirements are getting higher and higher, the state immediately 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 performance. Interior parts distribution performance, including odor test, formaldehyde content determination, condensation components, total carbon emissions.
