Embodiment 1

[0018] Put 400 grams of phthalocyanine blue pulp, 1000 grams of iron oxide yellow, 1500 grams of light calcium carbonate, and 800 grams of water into a 5L kneader, knead for 1 hour, then dry in a "drying room" at 100 ° C, grind and pulverize, A dark green composite green pigment with a 325-mesh sieve residue of less than 0.3% is obtained.

[0019] The kneader is a general-purpose equipment, and the model of Rugao Jiubao Vacuum Kneader Machinery Co., Ltd. is NL120 product;

[0020] The kneading torque is 50000NM, and the kneading time is 5 minutes;

[0021] The drying temperature is 200°C;

[0022] Composite pigment standards were used for detection, and the results were as follows:

Abstract

The invention provides a wet process preparation method of a hydrophilic composite pigment, comprising the steps: 'pigment paste' is sequentially compounded by kneading, dried, crushed and screened to obtain the products. The method saves the consumption of organic pigment, the power consumption and water loss, greatly reduces the noise, and improves the production environment of the operating workers.

Description

technical field [0001] The invention relates to a method for preparing a hydrophilic composite pigment. Background technique [0002] Hydrophilic composite pigments currently consume a lot in the application of cement and mortar coloring. They are mainly used for coloring of wear-resistant floor materials such as concrete tiles, exterior wall mortar, factories, warehouses, shopping malls and garages under residential buildings, etc. . Green and blue hydrophilic composite pigments are used domestically for the coloring of cement and mortar, up to 10,000 tons per year. [0003] Taking "Iron Phthalo Green" pigment as an example, the usual production method is to disperse the pre-wetted phthalocyanine blue pigment, iron oxide yellow pigment, and calcium carbonate in a high-speed "disperser" for 2 hours at a high speed, and then bake Dried, crushed and packaged. The disadvantages are high power consumption and water consumption, high noise of the machine, and low compound forc...
