Problems solved by technology

However, in-house experiments have shown that PVC dyed with these coated pigments does not have a sufficiently higher thermal stability than PVC dyed with uncoated pigments
In-house experiments have also shown that PVC dyed with other inorganic aluminum compounds such as aluminum oxide or aluminum hydroxide or magnesium phosphate is likewise not more thermally stable than PVC dyed with uncoated iron oxide

example

[0114] Example 1 (comparative example):

[0115] 145.5g of 110 Pigment and 4.5 g of calcium stearate were added to a Henschel FM4 mixer (from Thyssen Henschel). The two substances were mixed together at room temperature (20°C to 25°C) and 1000 rpm for 20 minutes. The powdered product was used for testing without further treatment.

example 2

[0116] Example 2 (comparative example):

[0117] 141g of 110 pigment and 9 g of calcium stearate were added to a Henschel FM4 mixer. The two substances were mixed together at room temperature (20°C to 25°C) and 1000 rpm for 20 minutes. The powdered product was used for testing without further treatment.

example 3

[0121] 145.5 g of Pigment Starting Material 1 and 4.5 g of calcium stearate were added to a Henschel FM4 mixer. The two substances were mixed together at room temperature (20°C to 25°C) and 1000 rpm for 20 minutes. The powdered product was used for testing without further treatment.

Abstract

The invention relates mixtures of pigments containing at least one inorganic compound selected from among the group consisting of iron oxides, iron oxide hydroxides, zinc ferrites, zinc oxides, magnesium ferrites and manganese ferrites, said at least one inorganic compound being provided with a coating containing at least one magnesium or calcium hydroxide or oxide, and at least one calcium salt or magnesium salt of a fatty acid, methods for the production of said mixtures, the use thereof for dyeing polyvinyl chloride (PVC), methods for dyeing PVC, PVC dyed with mixtures of said type, and plastic products containing mixtures of said type.

Description

technical field [0001] The present invention relates to mixtures of pigments and calcium or magnesium salts of at least one fatty acid, processes for the production of these mixtures, the use of these mixtures for dyeing polyvinyl chloride (PVC) and methods for dyeing PVC and dyeing with such mixtures PVC, and also to plastic products comprising such mixtures, the pigments comprising at least one inorganic compound selected from the group consisting of: iron oxide, iron oxyhydroxide, zinc ferrite, zinc oxide, magnesium ferrite and manganese ferrite, wherein the at least one inorganic compound is provided with a coating comprising at least one hydroxide or oxide of magnesium or calcium. Background technique [0002] PVC is primarily used in the construction sector as a raw material for, for example, window profiles, pipe fittings, floor coverings and roof membranes. Rigid and flexible films are likewise produced from PVC. PVC is also frequently used as insulation for electr...
