example 1

[0092] at room temperature to 15.0kg Add 0.150 kg of Energol RC-R100 compressor oil to 130 iron oxide red pigment and heat the mixture to about 100°C, and mix in a 75LFM75 Hasselblad mixer for about 5min, then add 1.32kg of 30332 wax and 1.32kg And the whole mixture was further mixed for about 15 min (tool speed about 780 rpm) and heated to about 200°C in the process. Measure the temperature in the product.

[0093] The reagent is then discharged through a valve, cooled, sieved and weighed. Yields of reagents were calculated for the entire particle size range between 1 mm and 6 mm (Table 1).

example 2

[0095] at room temperature to 15.0kg Add 0.150kg of Energol RC-R100 compressor oil to 130 iron oxide red pigment, 1.32kg of 30332 wax and 1.32kg The mixture was mixed in a 75 LFM75 Hasselblad mixer for about 15 min (tool speed about 780 rpm) and heated to about 200°C during the process. Measure the temperature in the product.

[0096] The reagent is then discharged through a valve, cooled, sieved and weighed. Yields of reagents were calculated for the entire particle size range between 1 mm and 6 mm (Table 1).

example 3

[0098] at room temperature to 15.0kg Add 0.150kg of Energol RC-R100 compressor oil to 130 iron oxide red pigment, 1.32kg of 30332 wax and 1.32kg And the mixture was mixed in a 75 LFM75 Hasselblad mixer at up to about 130° C. for about 35 min without external heating (tool speed about 780 rpm). Measure the temperature in the product.

[0099]The reagent is then discharged through a valve, cooled, sieved and weighed. Yields of reagents were calculated for the entire particle size range between 1 mm and 6 mm (Table 1).

Abstract

Agent comprises at least one inorganic pigment, oil, Fischer Tropsch wax with a solidification point of 50-140[deg] C and a needle penetration at 25[deg] C of up to 1 mm, and at least one second wax which is not Fischer Tropsch Wax and not polyolefin wax, with a solidification point between 50-140[deg] C. At least 50 wt.% of the agent has a particle size of >= 1 mm. Independent claims are also included for: (1) preparing the agent, comprising (a) mixing at least one inorganic pigment with an oil, (b) mixing the mixture with at least one Fischer Tropsch wax and a second wax, and (c) mixing at a temperature more than the solidification point of Fischer-Tropsch wax and the second wax, and / or (i) mixing at least one inorganic pigment with Fischer-Tropsch wax and second wax, (ii) mixing the mixture with at least one oil, and (iii) mixing at a temperature more than the solidification point of Fischer-Tropsch wax and the second wax; and (2) coloring building materials, comprising mixing the composition with the material above its softening point.

Description

technical field [0001] The present invention relates to agents comprising at least one inorganic pigment, one or more oils, at least one Fischer-Tropsch wax and at least one second wax, to a process for their production and to their use for coloring construction products, preferably asphalt , the use of bitumen, bituminous mixtures, tars and tar-containing compositions, and also to a method for coloring building products and building products colored with these agents. Background technique [0002] field of use [0003] Processing pigments to achieve optimum color perception requires grinding the pigments into primary particles. The resulting powder is very prone to dusting due to its very fine subdivision and tends to stick to each other and to packaging, machine parts and metering equipment. Substances identified as hazardous by toxicologists therefore require measures to be taken during processing to avoid any harm to people and the environment due to the dust generated...
