Abstract

The present invention relates to a pigment, particularly to a grinding-free environmental-protection pigment, which is characterized by comprising a pigment and an anti-flocculation agent coated on the pigment surface. According to the present invention, the pigment particles are subjected to the anti-flocculation agent surface coating treatment, and the grinding is performed through the special process so as to improve the anti-flocculation ability and avoid the re-agglomeration, such that the grinding-free environmental-protection pigment can be directly used; and the ink and coating material production process is simplified, and the production energy consumption and the production cost are reduced.

Description

technical field [0001] The invention relates to a pigment, in particular to a non-grinding environment-friendly pigment. Background technique [0002] The initial particle size of the pigment is small, because its surface energy is low and it tends to flocculate. Therefore, the pigments currently on the market are aggregated pigment particles and cannot be used directly. Therefore, a large amount of additives will be added to the production process of inks and coatings. agent and grind it to disperse it. [0003] For example, a Chinese patent discloses a grinding and dispersing device for organic pigments, application number: 200610066215.9, application date: 2006-03-29, including a grinding cylinder whose inner cavity maintains a certain temperature and vibrates axially at a certain frequency, and one end is inserted into the The rotating shaft of the grinding cylinder is sequentially fixedly connected to several blade groups on the rotating shaft in the grinding drum, eac...
