Definitions
- Optical brighteners for plastics are marketed as fine powders that are not flowable and tend to generate dust when charging.
- the associated ecological disadvantages of such dusts in general are known.
- irregularities can occur in the lightened plastic due to the fact that, with different grain size of the brightener particles, irregularities can also be observed in the lightened plastic.
- the powder application of the brightener can lead to an irregularly fluorescent appearance, which is particularly noticeable under UV light (max. 376 nm) due to the formation of dots and stripes.
- UV light maximum. 376 nm
- the object of the present invention is to formulate an optical brightener in such a way that it is dust-free and free-flowing to handle on the one hand and on the other hand produces homogeneous brightening effects in plastics.
- the application technology for loading plastic additives with waxes is state of the art.
- the easiest way to do this is to premix the brightener with a powdered wax and heat the mixture to the softening point of the wax. Dust-free flowable granules are obtained by slowly cooling to room temperature while rotating the container.
- wax emulsions or water-dispersible wax formulations with the plastic additive homogeneous to mix in an aqueous medium, possibly at an elevated temperature and with a stirrer, forming a granular form of the additive loaded with wax.
- JP 10 251533 The methods described in JP 10 251533 are also possible, the wax coating being carried out using an isobutanol finish. The same applies to the use of a fluid bed method described in DE-A1 29 40 156 and WO 92/07912. Wax spraying described in DE 39 35 815 C2 or the wax application described in EP 1 081 195 by means of spray drying are also suitable methods.
- the brightener wax granules according to the invention have one
- Granules with a diameter of 0.1 to 2 mm are particularly preferred, since they are very free-flowing, easy to dose and low in dust and, after application, give homogeneous bulges.
- Waxes are not chemically defined uniformly and form a group of substances with the same or similar usage properties, characterized by special physical properties.
- the term "wax” describes a series of natural or artificially obtained substances which generally have the following properties: Kneadable at 20 ° C, hard to brittle hard, coarse to fine crystalline, translucent to opaque, but not glassy; Melting above 40 ° C without decomposition, already a little above the melting point, relatively low viscosity and not stringy, strongly temperature-dependent consistency and solubility, can be polished under slight pressure (cf. Ulimanns Encyclopedia of Technical Chemistry, Volume 24, 4th Edition 1983, pp. 1- 49. Verlag Chemie, Weinheim and Römpps Chemie-Lexikon, Volume 6, 8th edition 1988, p. 463, Franck'sche Verlagbuchmaschine).
- Preferred waxes are: natural waxes, such as plant waxes, e.g. Camauba waxes, candella waxes, animal waxes, e.g. Beeswax, modified natural waxes, e.g. Paraffin wax, micro waxes, semi-synthetic waxes, e.g. Montan ester waxes, or fully synthetic waxes such as polyolefin waxes, e.g. Polyethylene and polypropylene waxes, polyethylene glycol waxes, cycloolefin copolymer waxes, amide waxes such as e.g. N, N'-distearylethylenediamine.

- animal waxes e.g. Beeswax
- modified natural waxes e.g. Paraffin wax, micro waxes, semi-synthetic waxe
- polyolefin waxes and polyolefin waxes containing polar groups formed by subsequent oxidation of the polyolefin wax, by grafting reaction with a monomer containing carboxylic acid, carboxylic acid ester, carboxylic anhydride or hydroxyl groups.
- High-molecular weight compounds which have a waxy character and are preferably prepared by polycondensation or polyaddition processes are suitable as waxy polymers, for example thermoplastic polyester, epoxy, styrene-acrylate copolymer, styrene-butadiene copolymer, cycloolefin copolymer resins, such as ® Topas.
- the polymers In order to have sufficient solubility at elevated temperatures in the plastic and in organic solvents, the polymers usually have a number average molecular weight of up to 20,000. Waxes with a number average molecular weight of up to 10,000 are preferred, particularly preferably with a number average molecular weight of up to to 5000.
- the dropping point of the waxes used according to the invention or the softening temperature of the polymers is preferably in the range from 60 to 180 ° C., particularly preferably in the range from 80 to 140 ° C.
- the amount and type of wax or polymer can vary, especially to ensure compatibility with the application medium.
- optical brighteners used are non-ionic and independent of the chemical structure, characterized in that they are in the range of
- Preferred optical brighteners are represented by formulas 1 to 5.
- optical brighteners based on the plastic to be lightened, are usually between 1 and 1000 ppm depending on the plastic and the white to be achieved.
- quantities of 0.1 - 30% based on the total weight of the plastic to be lightened are usually between 1 and 1000 ppm depending on the plastic and the white to be achieved.
- the optical brighteners can be used individually or in a mixture. Synergistic effects can also be observed.
- the granules can be used to lighten high-molecular organic materials.
- These can be of natural or synthetic origin.
- it can be natural resins, drying oils or rubber.
- they can also be modified natural substances, such as, for example, chlorinated rubber, cellulose derivatives and, in particular, fully synthetic organic polymers (plastics) which are produced by polymerization, polycondensation or polyaddition.
- polyolefins such as polyethylene, polypropylene, polyisobutylene, substituted polyolefins such as polystyrene, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetals, polyacrylonitrile, Polyacrylic acid and polymethacrylic acid or their esters, or polybutadienes and copolymers thereof.
- polyesters From the class of plastics produced by polyaddition and polycondensation, mention may be made of: polyesters, polyamides, polyimides, polycarbonates, polyurethanes, polyethers, polyacetals and also condensation products of formaldehyde with phenols or urea, thiourea or melamine.
- the high-molecular material mentioned can be present individually or as a mixture in the form of plastic compositions or melts. It can also be in the form of its monomers which are polymerized after the brightener dosage.
- the improvement in levelness can be seen particularly well if the plastic to be lightened is subjected to foaming after the treatment.
- the high-molecular organic material mentioned can be present individually or in mixtures in the form of plastic compositions or melts. It is also possible to incorporate the shape of the optical brightener according to the invention into the monomers on which the polymers are based and to lighten the corresponding plastic by polymerizing the brightener-containing monomer.
