Abstract
The invention discloses a rust-preventing baking varnish treatment process of surfaces of clutches. The rust-preventing baking varnish treatment process comprises the steps of removing oil and rust of work-pieces. In the step of removing the oil of the work-pieces, the work-pieces are placed into sodium hydroxide solutions with the concentration ranging from 5% to 9%, rinsed in solutions with the temperature ranging from 60 DEG C to 70 DEG C for 5-8 minutes, then washed through flowing hot water with the temperature ranging from 40 DEG C to 50 DEG C for 4-5 minutes and finally dried through air after being cleaned. In the step of removing the rust of the work-pieces, rusts on the surfaces of the work-pieces with the oil removed are removed through grinding, and the work-pieces are cleaned through clean water and then soaked into rust-preventing oil with the temperature ranging from 30 DEG C to 40 DEG C for 40-50 minutes, wherein the rust-preventing oil is composed of, by weight, 4-6 parts of petroleum barium sulfonate, 1.5-3 parts of C8-C10 carboxylate, 6-8 parts of kerosene, 0.5-1.2 parts of Vaseline sodium tripolyphosphate, 3.5-5.5 parts of ethanediol and 15-20 parts of castor oil. The surfaces of the work-pieces are bright and attractive after the work-pieces undergo the baking varnish treatment process, the adhesive force of varnish is large, and the varnish will not peel off easily.
Description
Technical field
The invention belongs to metal parts technical field of surface, be specifically related to the antirust paint baking technique of a kind of clutch surface.
Background technology
The parts of clutch, after producing shaped, all need to carry out paint baking to various parts.In the baking finish process of prior art, be with former technique oil removing before baking vanish, rust wiped by emery cloth, then directly carries out baking vanish, makes baking vanish outward appearance coarse, the poor adhesive force of baking vanish, and the time one is long, and the paint of workpiece surface easily comes off.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the antirust paint baking technique of a kind of clutch surface.
For achieving the above object, the technical solution used in the present invention is as follows:
The antirust paint baking technique of a kind of clutch surface, comprises the following steps:
(1) workpiece deoils: workpiece is put into the sodium hydroxide solution that concentration is 5-9%, in the solution of 60-70 DEG C, clean 5-8min, then adopts the flowing hot water injection 4-5min of 40-50 DEG C, rinses rear air-dry process well;
(2) workpiece rust cleaning: by the workpiece sand paper after oil removing by clean for the polishing of the rusty stain on surface, after clear water is clean, workpiece is placed in antirust oil and soaks 40-50min, temperature 30-40 DEG C, described antirust oil by following component by weight percentage part form: barium mahogany sulfonate 4-6 part, C8-C10 carboxylate 1.5-3 part, kerosene 6-8 part, vaseline sodium phosphate trimer 0.5-1.2 part, ethylene glycol 3.5-5.5 part, castor oil 15-20 part;
(3) put into 0.2%-1.0% soda ash aqueous solution soaking 10-15min after being rinsed well by the workpiece after rust cleaning, re-use clear water and rinse well;
(4) after rinsing, workpiece is placed in phosphating coat solution to process, phosphating coat solution is made up of the phosphoric acid of the edta salt of the NaOH of 70-80g/L, 10-14g/L, the tartaric acid of 3-5g/L, the zinc oxide of 2-3g/L and 30-36g/L, its solvent is water, temperature remains on 25-30 DEG C, takes out and dry after surface forms phosphating coat;
(5) mixed solution workpiece after oven dry being placed in film agent and water soaks 6-10min, after surface of the work forms cured film, dry paint again at surface spray amino;
(6) by the workpiece after process of spraying paint be dry under the environment of 140-150 DEG C in temperature, be incubated cooling naturally after 40-50 minute, namely obtain the workpiece of baking vanish antirust treatment.
Film agent in described step (5) and the allocation ratio of water are 1:3.
Described phosphating coat solution is made up of the phosphoric acid of the edta salt of the NaOH of 75g/L, 12g/L, the tartaric acid of 4g/L, the zinc oxide of 2.5g/L and 33g/L, and solvent is water.
Beneficial effect of the present invention:
Process of the present invention is simple, convenient operation, this technique is by first forming phosphating coat at surface of the work, phosphating coat has the compact texture of tiny holes, increase surface of the work to amass, thus increase the contact area of coating, substantially increase the adhesive force of organic coating to workpiece, make the surface of the work after paint baking bright clean, attractive in appearance, the strong adhesion of paint, difficult drop-off.
