Description
Technical field
The present invention relates to a kind of fluorescent tracing environmental type polyethers corrosion and scale inhibition disperser (APEYYG) and preparation method thereof, be a kind of be applicable to industrial circulating cooling water system without phosphorus, without nitrogen, biodegradable and can realize online the detection and the multifunctional water treating agent of automatic chemical feeding, for the corrosion-mitigation scale-inhibition dispersion treatment of water quality, belong to corrosion and scale inhibition disperser preparation and the utilisation technology of water-treatment technology field.
Background technology
Recirculating cooling water system in industrial production, in use procedure due to the variation of the rising of the variation of the evaporation of moisture, pH value, temperature, flow velocity, the impact of the factors such as pressure of impurity, system in water, the alkaline earth metal cation that contains in water such as Ca

2, at pipeline, with deposited on surface of heat exchanger, become dirt (being commonly called as incrustation scale), thereby cause the heat exchanger heat transfer efficiency to reduce and cause underdeposit corrosion.So suppress dirty thing with highly effective corrosion and scale inhibition disperser, forming and prevent metallic corrosion, is one of gordian technique that keeps the good operation of cooling water recirculation system; Also in process water and wastewater treatment, to control the effective means that incrustation scale formed and prevented metallic corrosion.
more and the scale inhibitor effect of at present research water conditioner preferably mostly is phosphoric acid salt, as hydroxy ethylene diphosphonic acid (HEDP), Amino Trimethylene Phosphonic Acid (AMP) and 2 – phosphonic acids Ding Wan – 1, 2, 4 – tricarboxylic acid (PBTC) etc., although this type of water conditioner has excellent inhibition tosca performance and corrosion inhibition preferably, but HEDP, PBTC etc. are because relative molecular mass less (<600), functional group is less, inhibition and dissemination to calcium phosphate scale and ferric oxide particles are poor, less stable to zinc salt, in the water quality that contains high calcium and high ferro, easily form organic phosphoric acid calcium and the organic phosphoric acid iron that is insoluble in water, affected its application.The most important thing is can serve as because this type of water conditioner is phosphorous the nutritive ingredient of bacterium and algae in water, the eutrophication that easily causes water source causes the pollution of water resources; Along with the mankind to the pay attention to day by day of living environment and the increasingly stringent of environmental regulation, the environmental type water conditioner is subject to people's attention day by day, particularly enter 21 century, great revolutionary change has occurred in the developing direction of World chemical and chemical industry subject, and its sign is exactly the proposition of " Green Chemistry " concept.Therefore, the Green Water Treatment Reagents of the without phosphorus non-nitrogen of exploitation is imperative.
The more phosphate-free water treatment agent of research is the carboxylic-acid water conditioner now, as polyacrylic acid (PAA), poly-epoxy succinic acid (PESA) etc., although United States Patent (USP) 5062962 and 5147555 shows that PESA is to CaCO

4Scale inhibition effect is preferably arranged, but hinder the poor effect of calcium phosphate, and dispersion and inhibition poor-performing.U.S. Betz company released co-polymer of sulfonate AA – APES of new generation (Bing Xi Suan – allyloxy polyethoxye vitriol multipolymer) in 2003, resistance Ca

2Efficiency obviously improve, and AA – APES has higher holding capacity to the water hardness, suspended substance, temperature, is latest generation resistance Ca

2The phosphate-free water treatment agent of dirt, but it is poor in APES, still to contain the nitrogen element and the resistance calcium sulfate scale effect that cause the water source eutrophication.In addition, thereby the large shortcoming of phosphate-free water treatment agent one is can't not use ammonium molybdate spectrophotometry commonly used by phosphorous in its structure, thereby can't the concentration of water treatment agent be detected and automatic chemical feeding online.The trace analysis that appears as in the industrial circulating cooling water processing of fluorescence labelling polymkeric substance provides a kind of novel method fast and accurately, owing in its structural molecule, containing fluorophor, can obtain very rapidly and easily its drug concentration in system by the mensuration of the material to fluorescence labelling, thereby realize system is detected accurately with administration and controls, so just can avoid causing because the detection of water Chinese medicine is inaccurate the unfavorable factors such as corrosion and scaling, can better to water treatment agent, detect online and automatic chemical feeding.Greatly improved the accuracy of formation efficiency and control.Therefore, develop a kind of can fluorescent tracing and have a without phosphorus non-nitrogen environmental type water treatment agent that corrosion-mitigation scale-inhibition disperses can extensively be suitable for of multi-functional and industrial circulating water system, for the update of corrosion and scale inhibition disperser, have important scientific meaning and great using value.
The present invention adopts maleic anhydride open loop method green reaction technique to make polyether carboxylic acid's reaction monomers, and then and the fluorescent monomer copolymerization that contains unsaturated double-bond prepared a kind of can fluorescent tracing and have an environmental type polyethers water conditioner of excellent scale inhibition, inhibition and dispersing property.
