Abstract
The invention relates to the technical field of water treatment, particularly to an environment-friendly phosphorus-free scale and corrosion inhibitor and a manufacturing method for the same. The scale and corrosion inhibitor comprises the following ingredients in parts by weight: 15-30 parts of acrylic acid-acrylate copolymer, 5-10 parts of sodium molybdate, 5-10 parts of benzotriazole, 3-8 parts of zinc sulphate monohydrate and 60-80 parts of distilled water. The scale and corrosion inhibitor disclosed by the invention is phosphorus-free and pollution-free for environment, as well as is an environment-friendly water treatment chemical.
Description
Technical field
The present invention relates to water-treatment technology field, particularly a kind of non-phosphate environment-friendly type anti-incrustation corrosion inhibitor and method of manufacture thereof.
Background technology
Along with the development of society, shortage of water resources and pollution are on the rise.For this reason, various environmental regulations are put into effect in many countries and regions.Have water saving, energy-conservation, material-saving and therefore the water technology of a series of functions such as improve the quality of products also is able to develop rapidly as one, the more field of research is organic phosphoric acid corrosion inhibiting and descaling agent and copolymer anti-scale disperser aspect water conditioner both at home and abroad.Organic phosphoric acid; Especially organic multicomponent phosphoric acid and salt thereof; Stable chemical performance, ability comparatively high temps and pH value, " dissolving the limit effect " and characteristics such as " synergistic effects " being arranged significantly, is present widely used one type of water conditioner, like ATMP, HEDP, PBCTA etc.But organophosphorus can not suppress Ca effectively
3(PO4)
2Dirt, zinc is dirty and solve problem such as iron oxide precipitation, and itself is prone to form the organic phosphoric acid dirt.Simultaneously since phosphorus to the eutrophication in environment waters, promote the growth of bacterium algae and form " red tide ", cause contaminated water source.Therefore, the use of phosphorus is restricted, develops the main direction that low-phosphorous or phosphorus-free green Scale inhibitors has become current water conditioner research.Copolymer antisludging agent class (comprising binary, ternary, multiple copolymer) mainly contains acrylic type, toxilic acid (acid anhydride) type etc., and its scale-inhibiting properties is better, and some is a nontoxic type, but shortcoming is can not biological degradation.
This stern reality shows to press for develops a kind of compound treating agent for water treatment that can satisfy scale inhibition, inhibition requirement simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of non-phosphate environment-friendly type anti-incrustation corrosion inhibitor and method of manufacture thereof, mainly solve above-mentioned existing in prior technology technical problem, scale inhibitor of the present invention is not phosphorous, and environmentally safe is environmentally friendly water conditioner.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of non-phosphate environment-friendly type anti-incrustation corrosion inhibitor is characterized in that: it is 15～30 parts of acrylic acid and acrylic ester copolymers, 5～10 parts of Sodium orthomolybdates, 5 parts～10 parts of benzotriazoles, 3～8 parts of Zinc Sulphate Monohydrates, 60～80 parts of zero(ppm) water according to the composition of parts by weight.
A kind of method of manufacture of aforesaid a kind of non-phosphate environment-friendly type anti-incrustation corrosion inhibitor is characterized in that: its process step is, A, zero(ppm) water is added in the reaction vessel, heats to 45 ℃, stirs; B, in reaction vessel, add acrylic acid and acrylic ester copolymers, Sodium orthomolybdate stirs, thorough mixing; C, in reaction vessel, add benzotriazole, Zinc Sulphate Monohydrate and stir, thorough mixing stirs and reduces to room temperature after 1～1.5 hour and get product.
The advantage that prescription of the present invention and method can embody is.
1, the Sodium orthomolybdate that uses among the present invention belongs to positive type oxide film inhibiter, on anode iron, forms ferrous-high ferro-molybdenum oxide passive film and a corrosion inhibition, and not resembling phosphorus easy generation phosphorus dirt and water body has eutrophication.
2, the acrylic acid and acrylic ester copolymers of using among the present invention has the calcium sulfate of inhibition, lime carbonate, calcium phosphate and fouling of phosphonic acids calcium and functions such as dispersing iron oxide, silt, plays the scale inhibitor effect.
3, scale inhibitor of the present invention is not phosphorous, and environmentally safe is environmentally friendly water conditioner.

Embodiment 2:A, zero(ppm) water is added in the reaction vessel for 80 parts, heats, stir to 45 ℃; B, in reaction vessel, add 20 parts of acrylic acid and acrylic ester copolymers, Sodium orthomolybdate stirs thorough mixing for 8 parts; C, in reaction vessel, add 8 parts of benzotriazoles, 5 parts of Zinc Sulphate Monohydrates and stir, thorough mixing stirs and reduces to room temperature after 1～1.5 hour and get product.
Embodiment 3:A, zero(ppm) water is added in the reaction vessel for 80 parts, heats, stir to 45 ℃; B, in reaction vessel, add 30 parts of acrylic acid and acrylic ester copolymers, Sodium orthomolybdate stirs thorough mixing for 10 parts; C, in reaction vessel, add 10 parts of benzotriazoles, 8 parts of Zinc Sulphate Monohydrates and stir, thorough mixing stirs and reduces to room temperature after 1～1.5 hour and get product.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
