Abstract
The present invention relates to a degreasing, rust-removing, passivating and bonderizing liquor for treatment of workpiece surface. Said degreasing, rust-removing, passivating and bonderizing liquor is made up by using phosphoric acid, aluminium, dodecyl sodium sulfonate or petroleum sodium sulfonate, potassium dichromate and water and making them pass through such processes of proportioning, filtering, mixing and packing. Its use temp. is 5-65 deg.C, and its rust-resisting time is up to above 2 years. It is non-toxic, odourless and can be extensively used for surface treatment of various metal products.
Description
The present invention relates to a kind of reaction solution that metal material surface is handled, particularly a kind of degreasing and rust removal Tunization wide temperature rang phosphating liquid.
The use temperature narrow range of existing phosphatization liquid, the antirust time is shorter, and extension frost phenomenon is in various degree arranged, and result of use is undesirable.
The objective of the invention is in order to overcome above-mentioned weak point, and provide a kind of use temperature wide ranges, the antirust time is long, the processing workpiece surface is level and smooth, the tough and tensile densification of phosphatize phosphate coat, there is not the white phenomenon of extension, can be with the one step completed degreasing and rust removal passivation of operation wide temperature rang phosphating liquid such as oil removing, rust cleaning, phosphatization, passivation.
Technical solution of the present invention is such: in the degreasing and rust removal passivation wide temperature rang phosphating liquid raw material, by weight being phosphoric acid 38%-50%, aluminium 0.5%-0.8%, Sodium dodecylbenzene sulfonate or petroleum sodium sulfonate 2%-5%, potassium bichromate 0.02%-0.04%, water 47.48%-56.16%, produce through dissolving, filter, mix, packing.
Embodiment: to prepare one ton of product is example, gets 85% industrial phosphoric acid 450kg, aluminium bits or aluminium powder 6kg, Sodium dodecylbenzene sulfonate 30kg, potassium bichromate 2kg, water 512kg:
1. get each 45kg of phosphoric acid, water and mix, progressively add aluminium bits or aluminium powder, and constantly stir, the question response after-filtration that dissolved, lowered the temperature.
2. mix with above-mentioned filtrate after potassium bichromate being dissolved in the suitable quantity of water, add the phosphoric acid and the water of surplus again.
3. Sodium dodecylbenzene sulfonate is dissolved in the above-mentioned solution, and constantly stirs, also can add again 0.2% be the 2kg iron filings reacted become deep green after, refilter.
4. barrel filling is packed.
The present invention is owing to adopt above prescription, and the Phosphating Solution of producing can be to metal steel particularly The operations such as the oil removing of iron member, rust cleaning, phosphatization, passivation are once finished, and simplify technology, Reduce cost. The processing surface of the work is level and smooth, and the tough and tensile densification of phosphating coat does not have the white phenomenon of extension, makes Be 5 ℃-65 ℃ with temperature, but air dry or washing oven dry. The antirust time is long, is used for Rust prevention during manufacture is assigned more than half a year at the aeration-drying environment, behind the japanning, outdoor antirust Time can reach more than 2 years. Stable performance, nontoxic, odorless can not cause hydrogen embrittlement, phosphatization The paint " priming paint " that film can be made function admirable uses. Be widely used in engineering goods, The oil removing of the steel pieces such as vehicle, pipeline, household electrical appliance, hardware, rust cleaning, Phosphatization, Passivation Treatment, and can improve the adhesive force of paint film.
Claims (2)
1. degreasing and rust removal passivation wide temperature rang phosphating liquid, it is characterized in that preparing in the raw material, by weight being phosphoric acid 38%-50%, aluminium 0.5%-8%, Sodium dodecylbenzene sulfonate or petroleum sodium sulfonate 2%-5%, potassium bichromate 0.02%-0.04%, water 47.48%-56.16%, produce through dissolving, filter, mix, packing.
2. degreasing and rust removal passivation wide temperature rang phosphating liquid as claimed in claim 1 is characterized in that adding in above-mentioned solution again and refilters after 0.2% iron filings have reacted, and produces through the barrel filling packing.
