Abstract

The invention discloses a water ceramic pigment and a production method thereof. The pigment consists of pigment base slurry and coloring material, wherein the pigment base slurry comprises water-soluble polyurethane resin, water-soluble acrylic resin, a pH regulator, dipropylene glycol butyl ether, antifoaming agent, flatting agent, thickener, ammonia water and other components. The water ceramic pigment can be directly used to draw pictures on the surfaces of smooth disks or other porcelain and glass products, does not need baking or drying, and is resistant to wash.

Description

technical field [0001] The invention relates to a ceramic pigment, in particular to a pigment which is directly painted on the surface of ceramic or glass and is not easy to wash off after drying and its production method. Background technique [0002] As the main raw material necessary for the production of ceramic products, pigments are mainly used for the decoration of various ceramic products. There are thousands of varieties of ceramic products, and the decoration methods are ever-changing. All of these are inseparable from ceramic pigments as long as they are decorated; [0003] According to different ceramic decoration methods, ceramic pigments are divided into: (1) body coloring pigments, (2) underglaze color pigments, (3) in-glaze color pigments, (4) overglaze color pigments; It is divided into high, medium and low temperature pigments, etc.; with the continuous development and expansion of the ceramic market in recent years, the annual demand for ceramic pigments i...
