A kind of cleaning rust remover
Technical field
The present invention relates to chemical field, relate to a kind of cleaning rust remover for ferrous metal surface particularly.
Background technology
Ferrous metal refers to iron, manganese, chromium and alloy thereof, as the ferrous metal such as steel, the pig iron, iron alloy, cast iron after cleaning, for preventing surface corrosion, antirust treatment must be carried out, such as surface apply rust-preventive agent.Comparatively early use the good slushing oil of rust-proof effect in prior art, form protective oil film by slushing oil in metallic surface, isolated water in air vapour is to corrosion of metal, thus it is antirust to reach the long period.But, slushing oil is used not only to need to consume a large amount of oil plant raw materials, exacerbate energy consumption, and also need when following process to clean rust cleaning further, not only create a large amount of discharge containing waste liquid, cause environmental pollution, second phase cleaning oil removing is time-consuming, increase cost, therefore, cleaning, dephosphorization, rust cleaning, anticorrosion and antirust in rust remover integrally can be completed in the urgent need to a kind of simultaneously.
Summary of the invention
Goal of the invention: be solve in prior art the technical problem existed, the present invention proposes a kind of cleaning rust remover, can complete cleaning, dephosphorization, rust cleaning, anticorrosion and antirust simultaneously.The technical problem that the present invention also will solve is the preparation method providing above-mentioned cleaning rust remover.
Technology contents: for realizing above-mentioned technical purpose, the present invention proposes a kind of cleaning rust remover, comprises the component of following parts by weight: 85wt% phosphoric acid 20 ~ 30 parts, naphthenic acid 10 ~ 15 parts, trolamine 2 ~ 5 parts, diethylenetriamine 0.15 ~ 0.30 part, 10 ~ 15 parts, bicarbonate of ammonia, sodium chlorate 0.5 ~ 0.8 part, 60 ~ 70 parts, water, aluminum napthenate 8 ~ 12 parts, sodium alkyl benzene sulfonate 5 ~ 8 parts and tripoly phosphate sodium STPP 10 ~ 15 parts.
Preferably, described cleaning rust remover comprises the component of following parts by weight: 85wt% phosphoric acid 25 ~ 28 parts, naphthenic acid 12 ~ 14 parts, trolamine 3 ~ 4 parts, diethylenetriamine 0.2 ~ 0.25 part, 12 ~ 13 parts, bicarbonate of ammonia, sodium chlorate 0.6 ~ 0.7 part, 65 ~ 68 parts, water, aluminum napthenate 10 ~ 11 parts, sodium alkyl benzene sulfonate 6 ~ 7 parts and tripoly phosphate sodium STPP 12 ~ 14 parts.
The most preferably, described cleaning rust remover comprises the component of following parts by weight: 85wt% phosphoric acid 26 parts, naphthenic acid 13 parts, trolamine 4 parts, diethylenetriamine 0.25 part, 13 parts, bicarbonate of ammonia, sodium chlorate 0.6 part, 68 parts, water, aluminum napthenate 10 parts, sodium alkyl benzene sulfonate 7 parts and tripoly phosphate sodium STPP 13 parts.
The invention allows for the preparation method of above-mentioned cleaning rust remover, comprise the steps:
(1) water of formula ratio is joined in reactor, under agitation add the bicarbonate of ammonia of formula ratio, sodium chlorate and aluminum napthenate, stir;
(2) stirring and dissolving completely after add the trolamine of formula ratio, diethylenetriamine, sodium alkyl benzene sulfonate and tripoly phosphate sodium STPP, be stirred to dissolving, add the naphthenic acid of formula ratio, after again stirring, add the 85wt% phosphoric acid of formula ratio, stir 20 ~ 30 minutes, obtain cleaning rust remover.
Beneficial effect: compared with prior art, cleaning rust remover tool of the present invention has the following advantages:
(1) the cleaning rust remover that prepared by the present invention can realize only needing a procedure can complete the cleaning of ferrous metal surface, dephosphorization, rust cleaning, anticorrosion and antirust simultaneously, for ferrous metal surface process decreases multiple working procedure, ferrous metal surface matrix is made no longer to suffer peracid.
(2) preparation method of the present invention is easy, and material source is extensive, can increase substantially effect, improves yield rate of becoming a useful person.
(3) cleaning rust remover of the present invention thoroughly can eliminate the pollution to social environment such as chlorion, ferrous ion, sulfate radical, sulfurous gas, greatly reduces energy consumption and labor force's consumption, protects the safety of operator simultaneously.
