Description
Technical field
The present invention relates to a kind of alkali hard water softening agent for softening of water.
Background technology
Hard water can bring very big harm in industrial production and life, and these hard water are passing through pipeline, container, boiler etc.
When heating or boiling, calcium, magnesium, iron plasma in hard water just taken off from water it is steady, decompose, overflow, be bonded in pipeline, in container
Wall.Particle content in water is more, and the hardness of water is bigger, and caused incrustation scale is more.In industrial production, the time gets over
Long, fouling is more serious, first blocks pipeline, reduces flow, second destroys equipment, container reduction of service life, disturbs normal raw
Production, bring greatly worried and trouble.Softening to hard water at present, which is substantially all, uses what is be made up of resins exchange device
Water-softening equipment is handled, but this device input is big, and efficiency is low, and troublesome maintenance, expense is also very high, it is difficult to
Promoted the use of again in actual production.
Therefore it is badly in need of that a kind of cost is low, safe and effective water softening product in the market.
The content of the invention
It is an object of the invention to provide a kind of alkali hard water softening agent, its is easy to use, and configuration is simple, and cost is low, can have
Effect reduces hardness in water, and when recycling running water, container, pipeline are not in the phenomenon of fouling and microbial growth.From
And effectively save water resource, protection equipment.
To achieve the above object, the technical solution adopted by the present invention is：A kind of alkali hard water softening agent, it is characterised in that
Raw material composition comprising following mass percent：15-30% sodium ethylene diamine tetracetates, 5%-20% BITs,
0.5%-8% phosphonobutane tricarboxylic acids and appropriate pure water.
Further, also comprising essence and pigment.
Further, also prepared comprising methacrylate maleic acid by following steps：
Step 1：Equipped with condensing unit, thermometer, dropping funel, agitator small-sized stirred tank in add maleic acid
And deionized water, when being warming up to 80 DEG C, start that mole of methacrylate and ammonium persulfate, wherein methacrylate and maleic acid is added dropwise
Match as 1:1, ammonium persulfate monomer mass percentage is 1%；
Step 2：After methacrylate and ammonium persulfate are added dropwise, isothermal reaction 2-3 hours, cooling discharging, isobutyl is produced
Shown in the olefin(e) acid maleic acid aqueous solution, reaction equation and product structure following formula:
Further, the mass percent of the methacrylate maleic acid is 0.5-5%..
Further, the mass percent of the sodium ethylene diamine tetracetate is preferably 20-25%.
Further, the mass percent of the BIT is preferably 10-15%.
Further, the mass percent of the phosphonobutane tricarboxylic acid is preferably 1-5%.
Compared with prior art, the invention has the advantages that：A kind of alkali hard water softening agent of the present invention makes
It is simple with conveniently, preparing；Cost is relatively low, without special water softening system；Water softening effect is good, effectively can reduce in water
Hardness, when recycling running water, container, pipeline are not in fouling；Bactericidal property is excellent, avoids recycling in water
Microbial growth so as to effectively save water resource, protection equipment.
Embodiment
Further explanation is done to the present invention below.
Embodiment is as follows：In the present invention, unless specified otherwise, all degrees are all using quality as base
It is accurate:
