Definitions
- the present invention relates to a black-colored polyamide composition containing a chromium-containing azo dye in the form of a 1: 2 chromium complex, to the preparation of such a polyamide composition, and to the use thereof for producing black-colored polyamide molded articles and fibers.
- the invention further relates to a method for laser welding using at least one molded part based on such a polyamide composition.
- Polyamides are among the polymers produced on a large scale worldwide and, in addition to the main fields of application, films, fibers and moldings (materials) are used for a variety of other purposes.
- polyamides polyamide 6 (polycaprolactam) and polyamide 66 (nylon, polyhexamethylene adipamide) are the most widely prepared polymers.
- Most technically important polyamides are semi-crystalline or amorphous thermoplastic polymers, which are characterized by a high temperature resistance. The coloring and, if appropriate, the further processing of these polyamides takes place at high temperatures of generally above 240 ° C. and in some cases above 300 ° C. This places increased demands on the colorants used, whether pigments or dyes, in comparison with polymers which are processed at lower temperatures, such as PVC or polyethylene.
- dyes When used, especially in partially crystalline polyamides, dyes tend to migrate undesirably to the surface of the dyed moldings or fibers. With fibers, this leads to bleeding of the dye, reduced rubfastness and discoloration of materials that come into contact with the fibers. Due to the property of migrating conventional dyes are only limited suitable for use in the polymer matrix of polyamides. In contrast, pigments are generally readily usable with respect to migration.
- thermoplastic molding compositions which contain a polymer selected from styrene copolymers, PMMA and other polyalkyl methacrylates, polycarbonates and polyester carbonates and a pigment black.
- Carbon blacks generally show good properties in the coloring of thermoplastics, such as polyamides.
- semi-crystalline polymers when used in semi-crystalline polymers, however, they act as nucleating agents, ie they lead to an increase in the number of nuclei upon incorporation into the molten polymer and thus influence the crystallization behavior.
- the use of carbon blacks in partially crystalline polyamides leads to undesirable changes in the dimensional behavior of the parts produced from the polyamide. This is particularly problematic in applications requiring high dimensional stability, e.g. B. in the automotive sector with frame parts, covers, etc.
- EP 2 716 716 A1 describes black-colored polyamide molding compositions comprising nigrosine and a nucleating agent.
- Nigrosine is a mixture of synthetic black colorants and is obtained by heating nitrobenzene, aniline and aniline hydrochloride in the presence of an iron or copper catalyst. They occur in different versions (water-soluble, alcohol-soluble and oil-soluble).
- a typical water soluble nigrosine is Acid Black 2 (Cl 50420), a typical alcohol soluble nigrosine is Solvent Black 5 (Cl 50415), and a typical oil soluble nigrosine is Solvent Black 7 (Cl 50415: 1).
- Nigrosine is, however, not completely harmless in terms of a potentially harmful effect. So z. B.
- a joining partner in the range of laser wavelength used on a high degree of transmission and the other has a high degree of absorption.
- the joining partner with the high degree of transmission is irradiated by the laser beam essentially without heating.
- the irradiated laser energy is absorbed near the surface and converted into heat energy, wherein the plastic is melted. Due to heat conduction processes, the transparent component is also plasticized in the region of the joining zone.
- Conventional laser sources used in laser transmission welding emit in a wavelength range of approximately 600 to 1200 nm.
- Many non-additized polymers are largely transparent or translucent for laser radiation, ie they only absorb poorly. By suitable colorants, but also other additives, such as fillers or reinforcing agents, the absorption and thus the conversion of laser light into heat can be controlled.
- Absorbing pigments which are usually carbon black pigments, are frequently added to the absorbent joining partner. This procedure is not possible for the laser-transparent joining partner since polymers colored with carbon black do not have sufficient transmission for the laser light. The same applies to many organic dyes, such as. B. Nigrosine. There is thus a need for black-colored moldings which, despite their coloring, have sufficient transmission for the laser light, so that they can serve as the laser-transparent component in laser transmission welding. This would make it possible to produce purely black products by laser welding.
- the present invention is based on the object to provide new black colored polyamide compositions.
- the colorant should be advantageous for mass coloration of the polyamide, in which the colorant is incorporated homogeneously into the polymer.
- the colorant should be characterized in particular by a good stability and processability under the dyeing conditions. The aforementioned disadvantages of the previously used colorants should be avoided.
