Description
Technical field
The present invention relates to a kind of corrosion inhibiting and descaling agent and preparation method thereof, and in particular to a kind of low phosphine compound slow corrosion antisludging agent and its
Preparation method, belongs to water-treatment technology field.
Background technology
In chemical industry, the use of boiler is very frequent, and operating boiler usually has hard incrustation scale and corrosion, this
Fuel is not only wasted, boiler output is affected, meeting bombing, causes blowing out accident, affect its service life when serious.Therefore,
Improve the utilization rate of boiler, it is necessary to effectively corrosion-mitigation scale-inhibition is carried out in boiler.
Main at present is main corrosion inhibiting and descaling agent with zinc salt or organic phosphate, due to organic phosphine carboxylic acid and other scale inhibitions
Agent has good synergism, also relatively strong to the stability of chlorine, can effectively corrosion-mitigation scale-inhibition, and phosphine content is low,
Environmental pollution is little, has therefore suffered from extremely wide use；But organophosphors can not effectively suppress calcium phosphate scale and oxidation
The precipitation of ferrum etc., is also easy to produce calcium gel etc., therefore, single organic phosphine carboxylic acid can not play obvious corrosion-mitigation scale-inhibition effect
Really, it requires that various antisludging agents carry out compounding use, to reach more obvious corrosion-mitigation scale-inhibition synergism.
The content of the invention
Goal of the invention：The first object of the present invention is to provide a kind of low phosphine, environmental protection, anti-chlorine burn into and has good scale inhibition point
The low phosphine compound slow corrosion antisludging agent of scattered property and corrosion inhibition；The second object of the present invention is to provide the composite slow-corrosion scale resistor
Preparation method.
Technical scheme：A kind of low phosphine compound slow corrosion antisludging agent of the present invention, including organic phosphine carboxylic acid, poly- epoxy succinic
Sour sodium, poly (sodium aspartate), sodium gluconate and deionized water, the mass percent of each component are as follows：
Organic phosphine carboxylic acid：2%-20%；
Polyepoxy sodium succinate：6%-25%；
Poly (sodium aspartate)：15%-30%；
Sodium gluconate：2%-15%；
Deionized water：Surplus.
Preferably, the mass percent of organic phosphine carboxylic acid is 15%-20%.
Preferably, the mass percent of polyepoxy sodium succinate is 15%-25%, and the mass percent of sodium gluconate is
8%-12%.
Preferably, organic phosphine carboxylic acid is hydroxyphosphono acetic acid or phosphonobutane tricarboxylic acids.
The preparation method of low phosphine compound slow corrosion antisludging agent of the present invention, comprises the steps：Weigh a certain amount of organic
Phosphine carboxylic acid is dissolved in deionized water, sequentially adds polyepoxy sodium succinate, poly (sodium aspartate), sodium gluconate, uniformly
Stirring, obtains final product low phosphine compound slow corrosion antisludging agent.
Preferably, uniform stirring 0.5-1h, during stirring, keeping temperature is 30-50 DEG C.
Beneficial effect：Compared with prior art, advantages of the present invention is：(1) organic phosphine carboxylic acid that the present invention is selected contains
Carboxyl and phosphate, have stronger sequestering power to metal ion, have stronger inhibition and scale prevention ability；(2) present invention
From polyepoxy sodium succinate, poly (sodium aspartate) is without phosphorus non-N structure, and is biodegradable environmental friendliness
Product, has scale inhibitor double effects concurrently, and its scale-inhibiting properties is significantly better than organic phosphine acids polymers antisludging agent；(3) gather
There is between NaAsp, polyepoxy sodium succinate, organic phosphine carboxylic acid significantly collaboration resistance Calcium Carbonate, calcium sulfate, sulfur
The performance of sour barium dirt, both compounding uses, not only scale inhibition effect is good, goes back the content of relative reduction phosphorus, meets low phosphine row
The environmental requirement put；(4) present invention selects sodium gluconate, in its molecule contain multiple hydroxyls, then in aqueous solution it is right
Fe3+, Cu2+, Ca2+ plasma has fabulous complexing power, and many salts to these ions also have good
Deactivation is acted on, therefore, it can be coordinated with other compositions and collaboration be presented simultaneously as antisludging agent, corrosion inhibiter and dispersant
Effect.
