Description
Technical Field
The invention relates to the technical field of cleaning agents (IPC (industrial personal computer) classification number is C01B 15/10), in particular to a coated sodium percarbonate and a preparation method and application thereof.
Background
The explosion salt is a novel clothes cleaning product in recent years, and is different from the principle that conventional laundry detergent relies on a surfactant and enzyme to decontaminate, the main active ingredient of the explosion salt is sodium percarbonate, also called sodium peroxycarbonate or solid hydrogen peroxide, and is white granular inorganic salt, the aqueous solution of the explosion salt is alkaline, the explosion salt can be decomposed into sodium carbonate and hydrogen peroxide, after the powder explosion salt is melted by hot water, the particles continuously generate oxygen like explosion, so that the diffusion rate of the sodium carbonate can be accelerated, and meanwhile, organic pigment molecules in clothes fibers can be brought out, so that the effect of removing stains is further achieved, and the explosion salt is usually used as an auxiliary agent of the laundry detergent, and has the effect of oxygen bleaching. When the washing liquid or washing powder is added to soak clothes with stubborn stains in hot water, the washing liquid or washing powder can effectively clean, bleach and sterilize the fabrics, has a bleaching effect which is not obvious like that of chlorine-containing disinfectant such as 84 disinfectant, can be used for bleaching color clothes, and is widely accepted by consumers due to good cleaning effect.
However, there are also short plates for "explosive salts", such as those currently available on the market which are used only as laundry aids or are soaked with laundry liquids or powders. Or the washing liquid or the washing powder is used again for cleaning after soaking, namely, the washing liquid or the washing powder cannot be used as an independent washing product for cleaning clothes. On the other hand, "explosive salt" can only be dissolved in hot water or even boiled water at present, and the dissolution rate is slower, the phenomenon that particles adhere to the surface of clothes and cannot be dissolved can occur, and if water is continuously added, the "explosive salt" can be diluted to reduce the washing effect.
Chinese patent CN115006287a discloses an explosive salt and a preparation method thereof, 25g of the sample is placed in 150L of warm water with the temperature of 45 ℃ and 285s is needed for complete dissolution, chinese patent CN1976871B discloses sodium percarbonate particles, a production method and application thereof, and a detergent composition containing the same, and the sodium percarbonate particles are used as bleaching aids in the application method. Therefore, the problem that the cleaning effect of explosive salt and cold water are instant can not be solved simultaneously in the prior art.
