Description
Technical field
The invention belongs to sterilizing agent, SYNTHETIC OPTICAL WHITNER technical field, be specifically related to a kind of stable chlorine bleach liquor and preparation method thereof.
Background technology
Advantages such as clorox is a kind of application chlorine oxygenatedchemicals very widely, is a kind of strong oxidizer, SYNTHETIC OPTICAL WHITNER, sterilizing agent and deodorizer, and is cheap because of it, that character is active, sterilizing ability is strong, be convenient to produce become a kind of Chemicals commonly used.Chlorine bleach liquor's main application is: the disinfection sanitizer of health and epidemic prevention, medicine and daily life; SYNTHETIC OPTICAL WHITNER in weaving and the printing industry; Oxygenant in the chemical industry etc.But,, its production, transportation, storage, sale and use etc. have all been brought great inconvenience because chlorine bleach liquor's self stability is relatively poor.
Cause chlorine bleach liquor's factors of instability to have four kinds: photolysis, thermolysis, acid are decomposed and the heavy metal ion catalytic decomposition.For fear of photolysis, people are stored in it in container of lucifuge, but that other causes chlorine bleach liquor's factors of instability also to play a part is very big, cause chlorine bleach liquor's available chlorine content just to descend more than 50% in less than one month time.The existing at present document that much improves clorox stability about the adding stablizer, stablizer commonly used is an oxymuriate, silicate, carbonate, phosphoric acid salt, boron nitride etc., big multi-method all is the pH value (general pH＞13) that improves the chlorine bleach liquor earlier, add stablizer, chlorine bleach liquor's stability of making like this strengthens to some extent, but general 8～9 months, available chlorine content will fall more than 10%, and the chlorine bleach liquor's of high pH value sterilization, bleaching effect can obviously descend, must add acid during use regulates, use very inconveniently, also can increase chlorine bleach liquor's usage quantity.
Summary of the invention
The present invention provides a kind of stable chlorine bleach liquor and preparation method thereof for solving the problems of the prior art.
The present invention is achieved by the following technical solutions:
A kind of stable chlorine bleach liquor, it comprises following material composition by weight:
