Problems solved by technology

[0004] The existing color paste has poor coloring ability, the color paste cannot be placed for a long time, it is easy to harden, and the practical effect is poor. When the color paste is emulsified, it is generally emulsified by direct stirring, and the vibration emulsification effect is not good. The fluidity of the color paste is poor and the dispersion effect is poor. Poor, during the color paste emulsification and mixing process, random sampling and observation cannot be performed, and shutdown operations are required. The emulsification process is discontinuous, which affects the quality of the finished color paste

Abstract

The invention discloses a color paste formula for a water-based paint. The color paste is prepared from the following raw materials in percentage by weight: 30-40% of color paste resin, 10-20% of toner, 2-4% of dispersing agent, 10-20% of titanium dioxide, 20-30% of deionized water, 5-8% of emulsifying agent, 2-3% of anti-sticking agent, 2-3% of thickening agent, 2-5% of carboxylic acid and 1-2% of defoaming agent. Deionized water is used as a solvent to play a role in dissolving all components, the emulsifying agent plays a role in emulsifying and providing a carrier, toner plays a role in coloring, the dispersing agent contributes to particle crushing of all the components, dispersion stability is guaranteed, all the components are evenly dispersed in a system, and the defoaming agent isused for preventing the foaming phenomenon in the stirring process. The color paste is high in coloring capacity, can be placed for a long time without mildewing, can keep stable rheological property, and is wide in application range, non-toxic and high in compatibility.

Description

technical field [0001] The invention relates to the field of color paste processing, in particular to a color paste formula for water-based paint and a production process thereof. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings of artificial synthetic resins (such as acrylic resins). Describe the water-based coatings of artificial synthetic resins; [0003] Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings); water-soluble coatings use water-soluble resins as film-forming substances, represented by polyvinyl alcohol and its various modified products. In addition, there are wate...
