Abstract
The anti-rust snow melting antifreezing agent has added antirust agent in the amount of 1-5 wt%. The antirust agent is citrate, including sodium citrate, magnesium citrate, calcium citrate, etc. and preferably sodium citrate. The anti-rust snow melting antifreezing agent can prevent metal part form rusting, and has no environmental pollution and toxin to animal and plant. It may be used for melting snow, defreezing and preventing freezing in road, airport, park, yard. The present invention is suitable for mechanical application and manual throwing.
Description
Technical field
The present invention relates to snow-melting antifreezer, particularly a kind of novel having suppresses the rust-proof type snow-melting antifreezer that the metal rust produces.
Background technology
Han Leng area in the winter time, owing to snowfall makes traffic difficulties, so the measure that various countries generally take to shed snow-melting antifreezer solves the traffic problems that cause because of snow, ice winter.In a variety of snow-melting antifreezers, inorganic salts thaws soon because of its snow melt, and is economic and practical and be widely used.Yet inorganic salts mostly is in three kinds in the sodium-chlor, magnesium chloride, calcium chloride two kinds mixture or mixture, and these materials have corrosive nature to metal objects such as way mark, automobile chassises.As the countermeasure that solves metallic corrosion, the rust-proof type snow-melting antifreezer of now existing part as interpolation Starso or phosphoric acid salt, though these products can suppress the generation of metal rust,, therefore be difficult to be used more widely because of himself all has bad influence to animal, people's skin and environment.
Therefore, provide a kind of metal rust of can suppressing to produce and do not cause the brand-new rust-proof type product of secondary pollution to necessitate again.
Summary of the invention
The purpose of this invention is to provide a kind of rust-proof type snow-melting antifreezer, both can overcome the shortcoming that traditional snow-melting antifreezer easily produces the metal rust, can overcome the deficiency that other rust-proof type snow-melting antifreezer easily causes environmental pollution again, for people provide brand-new product.
The present invention adds rust-preventive agent in inorganic salt type snow-melting antifreezer, it is that the composition of the salt that constitutes of formula M N constitutes, wherein M=sodium-chlor, calcium chloride, sodium-chlor and calcium chloride or sodium-chlor and magnesium chloride, and N is the solubility Citrate trianion; Said Citrate trianion accounts for the 1-5% of said composition weight; Weight ratio=the 5-7 of sodium-chlor and calcium chloride: 3-5; Weight ratio=the 5-7 of sodium-chlor and magnesium chloride: 3-5.
Said Citrate trianion comprises, Tripotassium Citrate, ammonium citrate, magnesium citrate or citrate of lime.With the Trisodium Citrate is best.
The preparation method of rust-proof type snow-melting antifreezer of the present invention is characterized in that comprising the steps:
Compound rust-proof type snow-melting antifreezer is pressed sodium-chlor and Citrate trianion 6: 1 mixed, carry out granulation by general prilling granulator then, obtain the particle of 1-8mm, and then this particle mixed in sodium-chlor and chloride-magnesium type or sodium-chlor and the chloride-calcium type snow-melting antifreezer in the ratio of 1-5% get final product.
The preparation method of the rust-proof type snow-melting antifreezer of mixed type, as sodium-chlor, calcium chloride and rust-preventive agent directly mixing granulation get final product.The preparation of calcium chloride rust-proof type snow-melting antifreezer can be in the slurry before the calcium chloride slice, after being sprinkled into Citrate trianion and mixing in the ratio of 1-5%, goes out the chlorination calcium tablet that the chlorination calcium tablet promptly obtains containing Citrate trianion through cylinder.
The application of antirust snow-thawing frostproofer is directly to shed, and is used for the snow melt, antifreeze and thaw in different kinds of roads, park, garden, place, airport.
Rust-preventive agent-Citrate trianion among the present invention has the chemical property that generates inner complex with metal ion; when contacting with metal object; form chela and molecular balance in the metallic surface; change the oxidized characteristic of metal; and the formation layer protecting film stops metal to be corroded; suppress the generation of metal rust effectively; vitamin P salt is as organism in addition; have characteristics nontoxic, harmless, high resolution again; it can be by biological degradation simultaneously; therefore environmentally safe, the present invention is to provide a kind of snow-melting antifreezer of environment-friendly type.
Embodiment
Embodiment 1:
With sodium-chlor 600kg; trisodium citrate 100kg; pour in the mixing tank for coating colors respectively; open mixing tank for coating colors, mix blowing after 10 minutes, deliver to tablets press through worm conveyor; carry out granulation; the particle of mechanical compaction directly enters the sieve apparatus screening, can obtain qualified rust-preventive agent, and unacceptable product is got back to tablets press granulation again.With qualified rust-preventive agent 140kg, and sodium-chlor 460kg, calcium chloride 400kg pours into respectively in the special-purpose mixing tank for coating colors, mixes 5 minutes to evenly, sends into feed bin by conveyor and packs, and promptly obtains 1 ton of qualified rust-proof type snow-melting antifreezer.
Embodiment 2:
The rust-proof type snow-melting antifreezer that Application Example 1 obtains carries out the rust-proof effect experiment:
(1) will measure earlier with tinsel and soak 2 minutes with 5% sulphuric acid soln, and remove plated film, and wash fast successively → alcohol flushing → acetone rinsing, nitrogen blowing is carried out drying, is placed on afterwards in the moisture eliminator, is numbered one by one, weighs.
(2) aqueous solution 80ml of preparation snow-melting antifreezer 3%, 1. salt magnesium type (sodium-chlor: 2. salt calcium type (sodium-chlor: the 3. rust-proof type snow-melting antifreezer (sodium-chlor: Calcium dichloride dihydrate: trisodium citrate=58: 40: 2) that obtains of embodiment 1 Calcium dichloride dihydrate=6: 4) magnesium chloride hexahydrate=6: 4), and get tap water 80ml, it is stand-by that above-mentioned four kinds of liquid are injected the culture dish that is numbered 1-4 Φ 90 * 15mm respectively.
(3) tinsel is put into one by one the culture dish that injects medicine, writing time and change of state, soak 7 day time, 5% hydrochloric acid (spirituous solution of interpolation 1%) was put in the tinsel taking-up, soaked 10 minutes in the 8th day, after brushing iron rust with toothbrush, clean with alcohol → acetone rinsing, the nitrogen blowing drying is weighed.
(4) rust-proof effect judgement schematics:
Corrosion speed=corrosion decrement ÷ experiment slice area ÷ tests fate (7 days)
Be Mdd=mg/dmdag
