Problems solved by technology

[0003] Generally, in order to have a certain compatibility with the paint during use, the selected medium is an alkyd resin similar to oil-based paint; although this method is cheap, there are certain disadvantages: such as color reproduction Poor performance, uneven coloring, because there is no professional technology and process, the pigment particles are relatively thick, the tinting power is not high, and the environmental pollution is serious. When added to the coating, the coating has poor light resistance and weather resistance after film formation, and is easy to fade and powder. Second, due to the limitations of the technology and raw materials of the general color paste, the products produced are subject to certain limitations in terms of storage, stability and temperature resistance. When the storage time is too long, the color paste will be in performance and Very limited in use

Abstract

The invention relates to environment-friendly general color paste and a preparation method thereof. The environment-friendly general color paste is prepared by using the following raw materials by weight: 40-60 parts of aldehyde ketone resin, 1 part to 2 parts of wet dispersing agent, 2-3 parts of anti-settling agent, 20-40 parts of toner and 20.5-32 parts of composite environment-friendly solvent. The color paste has the excellent performance of high solid content, low viscosity, low organic volatile and the like, meanwhile has good color keeping and light maintaining performance, is not prone to aberration change or yellowing and has good weather resistance and storage stability. Use and performance are not affected after the color paste is placed for more than one year under normal temperature state.

Description

technical field [0001] The invention relates to an environment-friendly universal color paste and a preparation method thereof. Background technique [0002] The traditional paint coloring is to use pigment powder to directly add to the paint, or first make the pigment into a paste, and then add it to the paint to color the paint. The latter is usually called a color paste. [0003] Generally, in order to have a certain compatibility with the paint during use, the selected medium is an alkyd resin similar to oil-based paint; although this method is cheap, there are certain disadvantages: such as color reproduction Poor performance, uneven coloring, because there is no professional technology and process, the pigment particles are relatively thick, the tinting power is not high, and the environmental pollution is serious. When added to the coating, the coating has poor light resistance and weather resistance after film formation, and is easy to fade and powder. Second, due t...
