Multifunctional environment-friendly color paste

Abstract

The invention discloses a multifunctional environment-friendly color paste which is prepared by the following components by weight: a wetting agent 2 to 20%, a dispersing agent 1 to 20%, a stabilizing agent 1 to 10%, organic pigments 30 to 50%, and the balance being water, wherein, the wetting agent is dihydric alcohol, or trihydric alcohol or a composition of dihydric alcohol or trihydric alcohol and a polyhydroxy-carboxyl copolymer with a molecular weight of 8000 to 10000 or a sodium salt thereof, the dispersing agent is one selected from the group consisting of sodium methylnaphthalene sulfonate, ammonium methylnaphthalene sulfonate, sodium lignosulfonate, sulfonic acid sodium salt of melamine-formaldehyde resin copolymer and sodium salt or ammonium salt of acrylic acid-itaconic acid copolymer or a composition of two or more selected from the group, and the stabilizing agent is a silane coupling agent or a titanate coupling agent. The multifunctional environment-friendly color paste provided in the invention is applicable to coloring of aqueous building coatings and pigment printing and pulp coloring of cotton, polyester cotton and blended fabrics, has a wide application scope, enables a paint film to have high water resistance, and has a high degree of dyeing.

Description

technical field [0001] The invention relates to a paint, in particular to a multifunctional environment-friendly color paste. Background technique [0002] In the production and application of paint colorants, the traditional method is to use non-ionic surfactants, wetting agents, water, etc. as carriers to disperse organic pigments in the system, and process them through physical grinding to obtain a fineness of less than 5 μm. of pulpy floats. [0003] The existing paint color paste has the following disadvantages: 1) nonionic surfactants can produce a large amount of foam when they are used in many fields; 2) the existence of nonionic surfactants makes the water resistance of the paint film in the paint products significantly reduced; 3 ) The paint color paste has a narrow application range and cannot color cotton fibers and paper fibers (the coloring rate is extremely low). Therefore, it is an urgent task at present to be able to produce a general-purpose multifunction...
