Description
Technical field
The present invention relates to derusting technical fields, more particularly, to a kind of reproducibility boron sulfuric ester rust remover.
Background technique
The materials such as ferrous metal, non-ferrous metal are placed under outdoor or open-air condition and get rusty easily, and not only influence presentation quality,
It also will affect being normally carried out for the techniques such as spray painting, bonding, such as handle not in time, scrapping for material but will be caused, it is unnecessary to cause
Economic loss.
The rust remover of the first generation is strong acid, and acid can be chemically reacted with iron rust and metal oxide, generates soluble-salt
Class, to achieve the purpose that derusting, while derusting, acid again can and underlying metal react and release hydrogen, Hydrogen Energy to iron rust and
The oxide skin of indissoluble generates pressure, be conducive to they peeling and high price iron reduction, accelerate the process of pickling, but traditional acid
There is also apparent defects for liquid processing method: the generation of a large amount of hydrogen can make steel generate Hydrogen Brittleness Phenomena i.e. in treatment process,
The mechanical properties decrease for causing metal influences the intensity of steel itself；Simultaneously easily formed acid mist, influence operator health and
Equipment and environment around corroding；The consumption of acid solution is also larger, increases processing cost；This kind of acid can form corruption to steel
Erosion.Furthermore the residue largely generated need to be discharged often, not only heavy corrosion industrial pipeline, but also contaminated soil and environment.
The rust remover of the second generation is nitrogenous and phosphorus chemical substance, although first generation rust remover can be overcome to be harmful to the human body,
The disadvantages of generating acid mist, corrosion substrate, but be easily accessible in water system and cause eutrophication.Second generation rust remover is to ring at present
It endangers caused by border and increasingly attracts much attention.Exploitation a new generation derusting product is extremely urgent.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, this application provides a kind of reducible sulfur acid esters rust removers.This derusting
Agent have quickly, thoroughly derust ability, not only derusting effect is better than strong acid or nitrogen phosphorus rust remover, but also environmentally protective, to people
Body is also without toxic side effect.
Technical scheme is as follows:
A kind of boron sulfuric ester reproducibility rust remover, preparation step are as follows:
(1) 40~80 parts of nonyl phenols or nonylphenol polyoxyethylene ether are put into reaction kettle, is heated to 120~140 DEG C, then
It is slowly added to 1~10 part of boric acid, is reacted 80~120 minutes after adding；
(2) it is cooled to 70~80 DEG C after completion of the reaction, is added 1~5 part of adjuvant, Temperature fall to room temperature；
(3) it is slowly added to 0.5~4 part of S under vacuum2O3Or SO3, stir while adding, be warming up to 60~70 after adding
DEG C, it reacts 80~120 minutes；
(4) 50 DEG C are cooled to after completion of the reaction hereinafter, being added 1~5 part of adjuvant, reaction 80~120 minutes is then natural
30 DEG C of cooling or less；
(5) 2~6 parts of reducing agents are added, stir evenly.
Preferably, the nonylphenol polyoxyethylene ether in NP-4, NP-7, NP-10, NP-15, NP-20 at least one
Kind.
Preferably, the adjuvant is selected from propylene glycol, glycerine, contracting two glycerol, D-sorbite, epoxidized soybean oil, season penta
At least one of tetrol, xylitol, mannitol.
Preferably, the reducing agent is sodium sulfite or ferrous sulfate.
The purity of each raw material is 99% or more.
The present invention is beneficial to be had the technical effect that
The rust remover that the present invention is prepared is for slightly becoming rusty, severe rust has derusting and cleaning ability well.Especially
It is that oxide skin can be removed rapidly and thoroughly.In general three layers of iron scale point, outermost layer is di-iron trioxide, in
Interbed is di-iron trioxide, ferroso-ferric oxide mixture, innermost layer are iron oxide, and iron oxide is sticky matter, and rust remover must have
There is superpower cleaning ability, otherwise extremely difficult iron oxide is removed from steel surface；And rust remover provided by the present application then can be thorough
Descaling.
Rust remover provided by the invention is a kind of concentration dosage form, water-soluble, nontoxic, and water is added and is made into 3~5%
It is non-volatile after rust remover liquid, do not corrode, does not need safeguard procedures, it is easy to use, it substrate to be processed can be held is dipped into and remove
It becomes rusty in agent, can also spray on rust remover to substrate to be processed, the methods of ultrasound, stirring can be subject to and accelerate derusting speed.
Detailed description of the invention
Fig. 1 is that this rust remover removes the effect slightly become rusty.
Fig. 2 is the effect that this rust remover removes severe rust.
The effect of Fig. 3 this rust remover scale removal.
