Definitions
- the present invention relates to a polymer composition and body trim parts made therefrom.
- Such body trim parts are suitable, in the assembled state, to withstand the temperatures of approx. 200 ° C. which occur in the cathodic dip coating without deformation, and furthermore they are free of glass fiber additive in order to achieve a Class A surface.
- body trim parts such as bumpers or fenders are usually made of metal.
- plastics are increasingly being used.
- Fiber-reinforced unsaturated polyesters and polyurethanes are used as thermosets.
- the most common thermoplastics are - for cost reasons - elastomer-modified polypropylenes.
- compositions based on various polyesters and polymer blends based on polyphenylene oxide and polyamide are used.
- Body trim parts made of plastic can either be painted separately from the metal body (offline), or integrated into the body painting process. In the latter case, a distinction is made between the assembly of the plastic part before (online) or after the cathodic dip coating (inline). With online painting, temperatures in the range between 195 and 210 ° C occur, which require a corresponding heat resistance of the materials used.
- the dimensional stability of materials in heat can be determined using various methods.
- the dimensional stability HDT according to DIN 53461 is the temperature at which the bending test specimen, which is heated in a liquid heat transfer medium and is mounted on both sides, rises to a defined deflection under a certain centrally applied force.
- the dimensional stability in heat according to Martens in accordance with DIN 53462 is characterized by the temperature which, under the action of force, has bent specimens heated in air at a specified heating rate by a specified amount.
- the Vicat softening temperature according to DIN ISO 306 is the temperature at which a defined indenter penetrates 1 mm deep into the surface of a plastic test specimen under a force of 10 or 50N with a constant temperature rise.
- the heat sag test has proven itself as a measure of the dimensional stability of a body trim part in the heat for a practical assessment.
- a 4 mm thick tension rod according to ISO 3167, manufactured by injection molding according to DIN ISO 294, is clamped horizontally in a device and the deviation from the horizontal is determined in millimeters at a specified temperature after a specified duration.
- Thermoplastic polymer compositions are made of, for example
- US-A-3379792 known. It describes a polymer composition consisting of polyphenylene ether and polyamide, which shows improved flow properties compared to pure polyphenylene oxide.
- the processability of such compositions, in particular by injection molding remains poor given the achievable MFR values of less than 10 g / min (280 ° C./5 kg).
- the polymer compositions according to US Pat. No. 3,379,792 show a low level of stiffness and poor stability at temperatures above 180.degree.

- thermoplastic materials based on elastomer-modified polypropylene and polyester mixtures do not meet the temperature requirements for online paintable body trim parts by far, blends based on polyphenylene oxide and polyamide only inadequately. Furthermore, both fluidity and appearance are unsatisfactory in practice.
- the object of the present invention is therefore to provide a polymer composition which can be used in the heat sag test at 250 ° C./30 min. a deviation of the horizontal on the test specimen is less than 15mm, which is suitable for the production of body parts that have a high surface quality, as well as good impact strength and a low thermal expansion with high rigidity and can be produced inexpensively.
