Abstract

The invention discloses application of sulfur/phosphorus hybrid polyether modified polycarboxylic acid in the fields of paint, printing ink, ceramics, adhesives and solar cells, and particularly relates to application of the sulfur/phosphorus hybrid polyether modified polycarboxylic acid in dispersing an organic pigment in water or an aqueous solution. The sulfur/phosphorus hybrid polyether modified polycarboxylic acid is prepared in the steps that by mass, 10-30 parts of acrylic acid, 1-10 parts of polyether and 20-50 parts of water are evenly mixed and heated to 50-100 DEG C, then 0.1-10 parts by mass of an initiator solution is added, a heat preservation reaction is carried out for 2-6 hours, and 6-20 parts by mass of a chain transfer agent solution is added to stop the reaction. The preparation method is wide in raw material source, green in preparation, simple and convenient to use and environmentally friendly. The problem that the organic pigment phthalocyanine copper is difficult to disperse in water is solved, and the application range of phthalocyanine copper is widened. A phthalocyanine copper water dispersion solution can be applied to the fields of paint, printing ink, ceramics, adhesives and solar cells.

Description

technical field [0001] The invention belongs to the field of pigment dispersants, and in particular relates to the application of a sulfur / phosphorus hybrid polyether modified polycarboxylic acid. Background technique [0002] Copper phthalocyanine was discovered in the 1930s and attracted attention due to its surprising stability to concentrated acids, alkalis, and high temperatures. Copper phthalocyanine molecules have a large conjugated system, which not only has excellent chemical stability, thermal stability, flame retardancy, light resistance and radiation resistance, but also has electrical conductivity, photoconductivity, gas sensitivity, electrical Luminescence, optical storage, catalytic activity and biomimetic properties. At present, copper phthalocyanine is developing into a multifunctional material, which will be widely used in industry and daily life, such as pigments, dyes, inks, solar cells, organic semiconductors with sensitive properties to gases, etc. ...
