Description
Technical field
The present invention relates to chemical fields, and in particular to the corrosion inhibiter for deicing snow melt.
Background technique
Except ice and snow melting agent is widely used in quick deicing, the snow melt of the regions such as winter road, bridge floor, square, park, change
Study point generally have the effects that absorb water, exothermic dissolution while the freezing point mechanism for reducing ice, snow-broth.Except ice and snow melting agent host agent point
For inorganic type (villaumite, nitrate etc.), organic type (acetate etc.) and three kinds compound, because of reasons such as using effect and costs,
China removes ice and snow melting agent with villaumite type (sodium chloride, calcium chloride, magnesium chloride etc.) as main family status kind at present.Due to making except ice and snow melting agent
Electrolyte solution is generated with process, and by the corrosion factors ingredient such as institute's chloride ion-containing in product, will lead to the corruption of metallic facility
Erosion and destruction, while water pollution and the harm to vegetation are generated, therefore, it is necessary to add corrosion inhibiter in except ice and snow melting agent formula
And consider the feature of environmental protection of recipe ingredient.Corrosion inhibiter refers to the substance that can effectively inhibit metal erosion, is divided into nothing by its component type
Type, organic type and three kinds compound, mainly by inhibiting cathode or anode electrochemical to react, or generate metallic surface passivating film,
Precipitation membrane, adsorbed film prevent the mechanism such as corrosive medium contact from playing inhibition, anti-rust action.Presently commercially available and research and development deicing are melted
Snow agent corrosion inhibiter main component have: nitrite, (poly-) phosphate, metasilicate, molybdate, tungstates, sodium gluconate,
One or more of methenamine, benzotriazole, tetraborate, thiocarbamide, poly-aspartate, sodium benzoate, zinc salt etc.
Compound.It is existing to be primarily present following defect and deficiency with corrosion inhibiter except ice and snow melting agent: 1) to metallic facility (predominantly carbon steel)
Protection effect it is undesirable；2) contain toxic (such as nitrite) or environmental hazard (such as phosphorous, zinc) substance, biological degradability
Difference is easy to produce water pollution and endangers vegetation growth；3) the preferable corrosion inhibiter price of existing environmental-protecting performance is all costly.
Summary of the invention
First goal of the invention of the invention is to provide new use of the cashew nut sulfocarbolate for the corrosion inhibiter of deicing snow melt
On the way, cashew nut sulfocarbolate has very strong anti-corrosion protection effect to metallic facility, moreover, cashew nut in deicing merging into nature
Sulfocarbolate is at low cost, pollution-free, is more suitable for deicing snow melt.
Realize that the scheme of goal of the invention of the invention is as follows:
Cashew nut sulfocarbolate is applied to the purposes of the metal inhibitor of deicing snow melt, and the purposes of the metal inhibitor is
Refer to that cashew nut sulfocarbolate plays corrosion mitigating effect by the stable metal surface formation hydrophobicity protective film that is adsorbed on.
In above scheme, the cashew nut sulfocarbolate refers to anacardol sulfonate sodium, sylvite, calcium salt, magnesium salts or ammonium salt
One or more of.
Second goal of the invention of the invention is for described in background technology in the prior art except ice and snow melting agent
Poor with anticorrosive property of the corrosion inhibiter to metallic facility, noxious material pollutes environment, and environmentally friendly corrosion inhibiter price is again costly to ask
Topic, the protective performance for providing a kind of pair of metallic facility (predominantly carbon steel) is superior, and biological degradability is good, is not likely to produce water pollution
And efficient, the environment-friendly type deicing snow melt special corrosion agent non-hazardous to vegetation growth.
Realize that the scheme of goal of the invention of the invention is as follows:
A kind of corrosion inhibiter for deicing snow melt comprising component and weight percent it is as follows:
Magnesium lignosulfonate 50%~80%；Cashew nut sulfocarbolate 20%~50%.
In above scheme, the cashew nut sulfocarbolate includes anacardol sulfonate sodium, sylvite, calcium salt, magnesium salts or ammonium salt
One or more of.
Beneficial effects of the present invention are as follows: the present invention is for existing except ice and snow melting agent neutralization technology delays metallic facility
Erosion, protection effect are undesirable, the defects of being also easy to produce water pollution and endangering vegetation growth and deficiency, using magnesium lignosulfonate and
Cashew nut sulfocarbolate compound, which is used as, removes the agent of ice and snow melting agent special corrosion, have inhibition, protection effect it is good, it is nontoxic, non-corrosive,
The superiority such as environmental-friendly, and there is raw material abundance, scheme easily to implement, low-cost advantage.

Magnesium lignosulfonate in the present invention is mainly derived from paper industry pulping waste liquor, and source very abundant is answered extensively
For fields such as oil drilling oil recovery auxiliary agent, cement water reducing agent, adhesive, dye dispersant, slurries additive agents.Lignin
Sulfonic acid magnesium can be directed to magnesium bisulfite boiling bagasse acidity pulping process waste liquid, and other lignin sulfonic acids can also be used
Salt (such as sodium salt, calcium salt) carries out ion exchange and is made.Industrial lignin sulfonate is containing hydroxyl, carbonyl, carboxyl, sulfonic group
Etc. the macromolecular compound of numerous reaction active groups.The present invention utilizes in magnesium lignosulfonate molecule largely containing lone pair electrons
Characteristic of the oxygen atom easily with metal (such as iron) coordination chelating, be allowed to except the corrosive ions generations such as chloride ion in ice and snow melting agent are competing
Striving property chemisorption and be covered on metal surface, meanwhile, the non-polar group in magnesium lignosulfonate molecule is then far from metal watch
Face forms protectiveness hydrophobic layer, effectively prevents the corrosion factors such as chloride ion close to metal surface.In addition, the present invention utilizes lignin
The synergistic effect effect of magnesium ion in sulfonic acid magnesium molecule, i.e. magnesium ion can form in metal surface and be insoluble in the magnesium hydroxide of water
Precipitation membrane has filled up the gap of lignin macromolecular protective film, ultimately forms stable inhibition protection film and inhibits electrochemical corrosion
Generation.
Anacardol is a kind of natural reproducible biomass product extracted from natural cashew nut shell oil, is currently used primarily in
Instead of or part replace phenol production High Performance Phenolic Resins, epoxy curing agent, bonding agent, coating, friction material etc.
Product.Anacardol basic chemical structure feature is long for the unsaturated hydrocarbons that the meta position of the phenolic hydroxyl group (hydrophilic radical) of phenol is connected to 15 carbon
Chain (hydrophobic grouping).Anacardol process for sulfonation and its research of the emulsifiability of surfactant product are it has been reported that as one kind
Oil-water system interfacial agent, cashew nut sulfocarbolate are applicable to the application fields such as detergent, oil displacement agent, but at present there has been no
Cashew nut sulfocarbolate is applied to the relevant report in deicing snow melt applied metal corrosion inhibiter field.Cashew nut sulfocarbolate is logical in the present invention
