Problems solved by technology

[0003] The technical problem to be solved by the present invention is that existing additives for metallic paint (silver powder paint) are prone to react with silver powder (aluminum), thereby affecting the storage stability of the paint and being expensive. A new water-based additive for one-component solvent-based silver powder paint, which can not only greatly improve the floating ability of aluminum powder, greatly reduce the cost, but also does not react with aluminum, and can be made into one-component (no separate packaging) paint, economical convenient

Embodiment 1

[0026] Weigh 1000 kg of tap water into a stainless steel tank, start stirring (800-1000 rpm), slowly add 1.94 kg of TFC-1 water-based dispersant, 7.76 kg of KF-01 water-based preservative, stir for 5 minutes and then slowly Add 19.4 kg of sodium alkylsulfonate anionic surfactant, stir for 20-30 minutes, and fill it in a plastic barrel (or non-iron barrel) for use. When adding to paint, add with stirring at 600-1000 rpm.

Embodiment 2

[0028] Weigh 800 kg of tap water into a stainless steel tank, start stirring (800-1000 rpm), slowly add 0.78 kg of 5041 water-based dispersant, 7.06 kg of AlexF-250 water-based preservative, and slowly add alkane after stirring for 5 minutes. 7.84 kg of sodium sulfonate anionic surfactant, stirred for 20-30min, filled with plastic barrels (or non-iron barrels) for use. When adding to paint, add with stirring at 600-1000 rpm.

Embodiment 3

[0030] Weigh 800 kg of tap water into a stainless steel tank, start stirring (800-1000 rpm), slowly add 0.78 kg of 5040 water-based dispersant, 7.06 kg of AlexF-251 water-based preservative, and slowly add alkane after stirring for 5 minutes. 7.84 kg of sodium sulfonate anionic surfactant, stirred for 20-30min, filled with plastic barrels (or non-iron barrels) for use. When adding to paint, add with stirring at 600-1000 rpm.

Abstract

The invention relates to an aqueous auxiliary agent for monocomponent solvent type aluminum paint. The aqueous auxiliary agent is prepared by adopting the following components according to the weight ratio: 1 to 2 percent of alkyl sodium sulfonate anionic surface active agent, 0.1 to 0.2 percent of aqueous dispersant, 0.5 to 1 percent of aqueous anti corrosion agent, and water for the residual. The invention has the advantages that: firstly, the required raw material is easily obtained, and is cheap; secondly, the preparation is simple; thirdly, the addition level range is large; fourthly, reaction with aluminum powder can not happen, therefore, the monocomponent paint can be produced; fifthly, the invention is of an environmental protection type product; sixthly, the original performances of the paint are not influenced.

Description

technical field [0001] The invention relates to a paint additive, in particular to a water-based additive for a solvent-type silver powder paint. technical background [0002] Industrial solvent-based floating silver powder paint can make the decorations have a metallic feel (silver color), so it is also called metallic paint (silver powder paint). The composition of metallic paint (silver powder paint) is: film-forming substance, floating silver powder (paste), solvent and additives, among which floating silver powder is metal aluminum coated with stearic acid on the surface to achieve the floating effect, and its floating ability directly affects Decorative paint. When the floating ability of the silver powder itself and its proportion in the paint are determined, people usually use additives (such as: silver powder alignment aids) to improve the floating ability of the silver powder paint. Since aluminum is a kind of active metal, although it is covered by stearic acid,...
