The invention discloses gradient activation type multi-effect
colored bleaching powder as well as a preparation process and application thereof, and belongs to the technical field of daily chemical washing. Comprising the following components: 48%-55% of
sodium percarbonate, 5.5%-8.5% of a gradient activation
system, 6.5%-10.8% of a double-effect color protection chelating
system, 4.7%-7% of a degradable
surfactant system, 3.7%-6% of a compound stabilizer, 16%-24% of a degradable filler, 0.15%-0.3% of essence and 0.08%-0.12% of a fluorescent whitening agent. According to the color
bleaching powder,
sodium percarbonate is used as a bleaching main body, an
active oxygen regulation-dye protection
closed loop is formed through chelating catalyst ions and physical isolation, and finally, under the full temperature range of 40-75 DEG C, the release amount of
active oxygen is kept to be larger than or equal to 88%, and it is ensured that the color change grade is larger than or equal to 4.5 grade; meanwhile, a degradable surfactant is adopted for compounding, the
biodegradation rate is larger than or equal to 98%, meanwhile, the
permeation efficiency of
active oxygen on stubborn stains is improved, and the removal rate is larger than or equal to 92%. All the raw materials are easy-to-purchase products, so that the problems of narrow temperature range, color protection difference and difficult
raw material purchase of the existing product are solved, and the detergent is suitable for washing household and commercial color fabrics and has a wide industrialization prospect.
