Embodiment 1

[0025] Embodiment 1: The natural ochre red ore is crushed to a particle size of 4 mm by a crusher, and then processed to a particle size of 40 mesh by Raymond mill. Take 180 kg of powder ore sample and add it to 500 L of water, and grind it with a sand mill. The obtained wet-grinding slurry was subjected to solid-liquid separation by a filter press (the water content of the filter cake was 36%), and the obtained filter cake was subjected to mechanical stirring, pulping and washing, and then pressure filtration again, and the solid-liquid mass ratio of the washing was controlled to be 35%. , the moisture content of the final filter cake obtained is 38%. Finally, the obtained filter cake was dried and pulverized to 150 mesh in a powerful dryer, then sent to a rotary kiln, roasted at 300ºC for 60 min, and then bagged. The sample was marked as H-1. L * , a * , b * See Table 1 for color parameters.

Embodiment 2

[0026] Embodiment 2: The natural ochre red ore is crushed to a particle size of 5 mm by a crusher, and then processed to a particle size of 60 mesh by Raymond mill. Take 100 kg of powdered ore sample and add it to 600 L of water, and grind it with a sand mill. The obtained wet grinding slurry was subjected to solid-liquid separation by a filter press (the water content of the filter cake was 38%), and the obtained filter cake was subjected to mechanical stirring, pulping and washing, and then pressure filtration again, and the solid-liquid mass ratio of the washing was controlled to be 37%. , the moisture content of the final filter cake obtained is 40%. Finally, the obtained filter cake is dried and pulverized to 200 mesh in a powerful dryer, and the sample is marked as H-2. L * , a * , b * See Table 1 for color parameters.

Embodiment 3

[0027]Example 3: The natural ochre red ore crusher was crushed to a particle size of 3.5 mm, and then processed by Raymond mill to a particle size of 100 mesh. Take 180 kg of powdered ore sample and add it to 550 L of water, and grind it with a sand mill. The obtained wet grinding slurry is subjected to solid-liquid separation by a filter press (the water content of the filter cake is 40%), and the obtained filter cake is subjected to mechanical stirring, pulping and washing, and then pressure filtration again, and the solid-liquid mass ratio of washing is controlled to be 40%. , the moisture content of the final filter cake obtained is 45%. Finally, the obtained filter cake was dried and pulverized to 160 mesh in a powerful dryer and then directly sent to the rotary kiln, roasted at 700ºC for 60 min and then bagged. L * , a * , b * See Table 1 for color parameters.

Abstract

The invention provides a processing technology of a natural ochre mineral pigment for ore color paintings, the natural ochre mineral pigment is obtained through crushing, grinding, wet grinding, filter pressing, washing, filter pressing, strong drying, (or roasting) and bagging, the content of Fe2O3 in natural ochre raw ore is not lower than 40%, the content of Fe2O3 after purification is not lower than 60%, and the particle size is not higher than 200 meshes. According to the processing technology and the process, the technical defects that a traditional natural ochre mineral pigment processing technology is tedious, time-consuming and labor-consuming are effectively overcome, and the prepared natural ochre mineral pigment is stable in chromaticity and particle size batch and high in color saturation and can be used as a rock color painting pigment with excellent performance.

Description

technical field [0001] The invention relates to a processing technology of a natural ochre red mineral pigment used for mineral color painting, and belongs to the technical field of environment-friendly inorganic pigments. Background technique [0002] Mineral color painting, also known as rock color painting, originated from ancient Chinese rock color murals, and is a form of painting within the Chinese culture. As early as the first century AD, mineral pigments were used as one of the raw materials for traditional rock paintings because their particles were independent of each other and insoluble in water, exuding crystal clear and thick colors, and had good durability and stability. The rock-colored murals such as the Grottoes, Fahai Temple in Beijing, Kizil in Xinjiang, and Yongle Palace in Shanxi still maintain their infinite artistic charm. Contemporary rock painting combines Eastern and Western painting styles in terms of techniques, and draws on Western painting art...
