Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: nanosized silicon with particle size of 5-100 nm is added as a light stabiliser to the recipe of the composition during mixture or synthesis of ingredients thereof. In the surface layer, particles contain silicon dioxide in amount of 0.25-2.5 wt %, having stable spectral absorption of medium-wave UV radiation in the 200-420 nm range. This effect is retained at high temperatures of approximately up to 650 K. ^ EFFECT: obtaining coatings which do not change colour and operational properties and retain colour- and weather resistance. ^ 2 tbl, 7 ex Изобретение относится к лакокрасочной промышленности. В рецептуру композиции в процессе смешения или синтеза ее ингредиентов в качестве светостабилизатора вносят наноразмерный кремний с размером частиц 5-100 нм. В поверхностном слое частицы содержат диоксид кремния в количестве 0,25-2,5% масс., обладающий устойчивым спектральным поглощением средневолнового УФ-излучения в диапазоне 200-420 нм. Этот эффект сохраняется при высоких температурах, примерно до 650 К. Полученные покрытия не изменяют цвет и эксплуатационные свойства, т.е. сохраняют свето- и атмосферостойкость. 2 табл.
