Description
【Technical field】
The present invention relates to chemical technology field, and in particular to a kind of rust remover and preparation method thereof.
【Background technology】
Metal gets rusty easily under being placed in outdoor or open-air condition, and it is a kind of chemical reaction to get rusty, and is substantially the oxygen of metal
Change reaction, metal rusting not only influences presentation quality, the technique such as can also influence to paint, be bonded is normally carried out, and these iron rust are tight
Ghost image rings the operation of subsequent technique and the quality of product, such as processes not in time, can more cause scrapping for material, and it is unnecessary to cause
Economic loss, so to metal carry out rust cleaning it is necessary.Existing derusting method is typically all to use chemical derusting, mainly
It is exactly that oxidation reaction occurs with iron rust using strong acid solution or strong base solution, so as to reach the effect of rust cleaning, but was using
Consumption deficiency may result in rust cleaning not totally in journey, and consumption will excessively corrode metal, and strong acid and strong base solution evaporation is excessive,
The inefficiency of rust cleaning, the metal secondary time of getting rusty is short after rust cleaning.
【The content of the invention】
It is an object of the invention to：Excessive, the low problem of rust cleaning efficiency, there is provided one kind is removed for existing rust remover consumption
The rust time is short, and rust cleaning effect is good, and metal is not susceptible to rust remover of secondary corrosion and preparation method thereof after rust cleaning, the rust remover
Preparation process is simple, preparation cost is low, is adapted to be promoted in this area.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of rust remover, the rust remover is to be composed of the following components in parts by weight：Tertiary sodium phosphate 15-25 parts, acrylic acid
Ester copolymer 12-16 parts, antimony oxide 14-18 parts, inositol hexaphosphate 10-20 parts, acrylamide 16-20 parts, tolyl
Triazole 6-8 parts, 16-24 parts of the acid of laurylene base fourth three, 11-17 parts of diethoxy estersil base ethane, dibutyl phthalate 6-
12 parts, fluorine carbon emulsion 8-12 parts, 6-8 parts, deionized water 30-40 parts of PERFORMANCE OF MODIFIED VERMICULITE powder.
In the present invention, further, the rust remover is to be composed of the following components in parts by weight：Tertiary sodium phosphate 18-23 parts,
Acrylate copolymer 13-15 parts, antimony oxide 15-17 parts, inositol hexaphosphate 13-17 parts, acrylamide 17-19 parts,
Tolyl-triazole 6.5-7.5 parts, 18-22 parts of the acid of laurylene base fourth three, 13-15 parts of diethoxy estersil base ethane, O-phthalic
Dibutyl phthalate 8-10 parts, fluorine carbon emulsion 9-11 parts, 6.5-7.5 parts, deionized water 33-37 parts of PERFORMANCE OF MODIFIED VERMICULITE powder.
In the present invention, further, the rust remover is to be composed of the following components in parts by weight：20 parts of tertiary sodium phosphate, third
14 parts of olefin(e) acid ester copolymer, 16 parts of antimony oxide, 15 parts of inositol hexaphosphate, 18 parts of acrylamide, 7 parts of tolyl-triazole,
20 parts of the acid of laurylene base fourth three, 14 parts of diethoxy estersil base ethane, 9 parts of dibutyl phthalate, 10 parts of fluorine carbon emulsion, change
7 parts of vermiculite power of property, 35 parts of deionized water.
In the present invention, further, the preparation method of the PERFORMANCE OF MODIFIED VERMICULITE powder is：Vermiculite is calcined at 400-500 DEG C
After 3-4 hours, clay into power, then be 10-15% hydrogen peroxide dippings 3-5 hours with mass fraction, last deionized water washing is dried
Powder is added to percentage by weight in 1-3% silane coupler solutions, then to carry out ultrasonic disperse after dry, is stirred, dried,
It is finely ground, obtain final product PERFORMANCE OF MODIFIED VERMICULITE powder.
In the present invention, further, the preparation method of the silane coupler is, first that silane coupler is soluble in water,
The solution that mass fraction is 0.5-2% is prepared into, glacial acetic acid is subsequently adding, its pH is modulated 5.5, stirred 5 minutes, obtained final product.
In the present invention, further, the time of the ultrasonic disperse is 30 minutes, and whipping temp is 80 DEG C, mixing time
It it is 30 minutes, drying temperature is 100 DEG C, drying time is 2 hours.
A kind of preparation method of rust remover as described above, concretely comprises the following steps：
(1) in parts by weight, deionized water is heated to 40-50 DEG C first, then by fluorine carbon emulsion be poured slowly into from
In sub- water, stir 3-5 minutes；Add tertiary sodium phosphate, inositol hexaphosphate and dibutyl phthalate, stir while
80-90 DEG C is heated to, 10-15 minutes is stood, mixed liquor A is obtained；
(2) toward add in mixed liquor A acrylate copolymer, acrylamide, tolyl-triazole, the acid of laurylene base fourth three,
Diethoxy estersil base ethane, stops heating after being heated to 80-90 DEG C, add PERFORMANCE OF MODIFIED VERMICULITE powder, stirs to normal temperature, obtains final product.
In sum, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, rust remover of the invention, the acid of laurylene base fourth three coordinates diethoxy estersil base ethane with preferably rust cleaning effect
Really, the rust cleaning time is shorter, but both combinations can cause the rate of volatilization of rust remover to be accelerated, thus can increase in descaling process
The usage amount of rust remover, at the same it is also amid a sharp increase to corrosion of metal, therefore tertiary sodium phosphate, inositol six are added in preparation process
Phosphate, tertiary sodium phosphate and inositol hexaphosphate can produce phosphotriester and sodium phytate, the phosphorus of inositol six each other
Sour sodium can be attached to metal surface and form a kind of oxide of densification with metal ion, prevent metal from being further corroded, and phosphorus
Sour three esters are relatively low because of its density, and the surface that can float to rust remover forms a kind of diaphragm, prevent the acid of laurylene base fourth three and two
The volatilization of ethyoxyl estersil base ethane, strengthens the stability of rust remover, makes rust remover not volatile, but also reduce rust remover
Mobility and adhesiveness, add fluorine carbon emulsion, PERFORMANCE OF MODIFIED VERMICULITE powder, and PERFORMANCE OF MODIFIED VERMICULITE powder is passing through immersion, ultrasonic disperse, drying it
Afterwards, in larger distance between atom, repulsive force is larger, in the ability of absorption water and in the coordination ability further, PERFORMANCE OF MODIFIED VERMICULITE
Powder is dissolved in fluorine carbon emulsion to add and can well solve the problems, such as that mobility and adhesiveness are not enough in rust remover, while changing
Property vermiculite power presence can be good at absorbing the moisture produced in descaling process, make more to coordinate between each component, common hair
The effect of waving.
2nd, rust remover of the invention, with rust cleaning effect well, corrosion will not be produced in descaling process to metal,
Metal can be more enduringly set to be no longer influenced by anticaustic after rust cleaning, its preparation process is simple, raw material extensively, is adapted at this
Promote in field.
