Abstract
The invention discloses a kind of decomposing hydrogen dioxide solution inhibitor, including following mass percentage composition, sodium gluconate 10~20%, five methene phosphoric acid 2~4% of diethylenetriamine, sodium hydroxide 1~2%, sodium benzoate 0.4%-0.6%, surplus is deionized water, five methene phosphoric acid of material therefor sodium gluconate and diethylenetriamine of the present invention instead of complexation of metal ions speciality HEDP, ATMP.Since the amount of all aobvious acid sodium hydroxide neutralized admittedly of two material of HEDP, ATMP increases, and lead to that crystalline object is precipitated with winter temperature drop bottom, solubility reduction, influences product quality.The additive amount that the present invention adds sodium hydroxide greatly reduces and is added the food-grade sodium benzoate of anticorrosive mildewproof effect, so that product is obtained quality guarantee, while hydrogen peroxide is difficult to decompose under general Conservation environment, the holding time greatly prolongs.
Description
Technical field
The present invention relates to chemicals technical fields, and in particular to a kind of decomposing hydrogen dioxide solution inhibitor and preparation method thereof.
Background technique
Hydrogen peroxide, that is, hydrogen peroxide (H2O2) aqueous solution, room temperature is colourless transparent liquid.It can only decompose under normal circumstances
Cheng Shui and oxygen.
Pure stabilized hydrogen peroxide is very good, but is limited to cost problem, nor more purer better.Analyze hydrogen peroxide not
Stability, mainly since the metal ion brought into production process can promote its decomposition.From cost consideration, reached in ion limit
Adding certain stabilizer in the case of target to keep the stability of hydrogen peroxide up to standard is mainstream thinking.This kind of stabilizer is mainly by gold
Category ion is adsorbed, is complexed, being chelated or these types of approach is combined with each other and plays stable effect.
Cotton fabric bleaching processing main purpose be removal natural pigment, improve the whiteness of fabric, meet white goods and
The requirement of light coloured fabrics processing.Hydrogen peroxide is the common oxidative bleaches of cotton fabric, chromatophagous total by oxidation reaction
Yoke system, achievees the purpose that bleaching.Hydrogen peroxide is a kind of mild oxidative bleaching agent, and the presence of the metal ions such as iron, copper can make
Hydrogen peroxide decomposes rapidly, causes loss of effective components and fabric strength to be damaged, being added usually in working solution has metal ion
The stabilizer of constraint effect.In the prior art, the variation due to weather throughout the year is relatively low material dissolution degree in winter temperature
Reduction causes crystalline object precipitation occur, unstable quality, and cosmetic variation is big.
The present invention is exactly the width in order to expand product energy bearing temperature, and appearance is unchanged when keeping temperature lower, without crystalline
Object is precipitated quality and is guaranteed, effectively the quality guarantee period of court of a feudal ruler long products.
Summary of the invention
The width for expanding product energy bearing temperature is provided it is an object of the invention to overcome the above problem, keeps temperature lower
When appearance it is unchanged, no crystalline object is precipitated quality and is guaranteed, effectively the hydrogen peroxide inhibitor of the quality guarantee period of court of a feudal ruler long products
And preparation method thereof.
To achieve the above object, the technical solution adopted by the present invention is that a kind of decomposing hydrogen dioxide solution inhibitor, which is characterized in that
Including following mass percentage composition, sodium gluconate 10~20%, five methene phosphoric acid 2~4% of diethylenetriamine, sodium hydroxide
