Embodiment Construction
[0016] The present invention is further described below in conjunction with embodiment.
[0017] The invention provides an ultra-low VOC water-based metal effect plastic paint, which is mixed with the following raw materials in weight percent:
[0018] All-solid water-based aluminum pigment 6-12%, deionized water 30-35%, water-based emulsion 47.6%-58.5%, thickener 1.6-2%, organic base 0.4-0.5%, heavy ester 2.5-3%, emulsifier Wet agent 0.4%-0.5%;
[0019] The all-solid water-based aluminum pigment is a water-based aluminum pigment in solid state, which is disclosed in related patent documents. The organic solvent is removed by vacuum heating, ie the volatile organic compound (VOC) content is less than 1000ppm. The water-based emulsion is a water-based acrylic emulsion or a modified water-based acrylic emulsion with a monomer residue as low as 1000ppm. The thickener is a non-associated alkali-swellable thickener. The organic base is N,N-dimethylethanolamine (DMEA) or 2-amino...
