Description
Technical field
The present invention relates to metal conditioner field, in particular, relate to a kind of Colloid titanium surface conditioner and system thereof
Preparation Method.
Background technology
Along with developing rapidly of metal-processing industry, the application that metal surface adjustment processes is increasingly extensive.Generally surface adjusts
It is long that the surface of agent adjusts the time, and prepared phosphating coat crystallization is thick, and film layer is thicker, and phosphating time is long, and phosphating equipment investment is big, energy
Consumption is high, acid mist is big, stability of solution is poor, sediment is many, it is loaded down with trivial details to adjust, environmental protection pressure is big, the unfavorable factors such as service life is short, and work
Part easily returns rust after phosphatization.
Summary of the invention
An object of the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of Colloid titanium surface conditioner, this glue titanium
Surface conditioner phosphate coating compact crystallization is uniform, and adhesive force and corrosion resistance significantly improve, in relatively low temperature and shorter
Just whole growth courses of conversion film can be completed in time.In phosphatization, film speed is fast especially, under normal circumstances, and phosphatization 30 seconds
Overlay film, i.e. has the most superior corrosion resistance in three minutes completely.
The two of the purpose of the present invention are to provide the preparation method of above-mentioned Colloid titanium surface conditioner.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of Colloid titanium surface conditioner, in terms of parts by weight, is made up of following raw material:
Sodium hydroxide 20-23 part, phosphoric acid 36-40 part, titanyl sulfate mixed liquor 13-16 part, sodium tripolyphosphate 24-30
Part.
Wherein said sodium hydroxide preferred 20.8-22.4 part；
Wherein said phosphoric acid preferred 36.6-38 part；
Wherein said titanyl sulfate mixed liquor preferred 14.6-15.2 part；Wherein said titanyl sulfate mixed liquor is
Titanyl sulfate: water=1:(1.5-2.5) (mass ratio), preferably 1:2；
Wherein said sodium tripolyphosphate preferred 24.4-28 part.
The preparation method of Colloid titanium surface conditioner of the present invention in turn includes the following steps:
(1) in reactor, titanyl sulfate mixed liquor is added；
(2) in reactor, add sodium hydroxide, be stirred, until sodium hydroxide is completely dissolved；
(3) being slowly added dropwise phosphoric acid in reactor, question response is complete；
(4) in reactor, add sodium tripolyphosphate, stir.
Wherein the mixing time in step (2) is 3-10 minute；Time for adding in step (3) is 1-3 hour；Step
(4) mixing time in is 1-3 hour.
The using method of Colloid titanium surface conditioner of the present invention is following (as a example by preparing 1000L):
First the tap water of 1/2 is added in groove, then start spray pump or blood circulation, gently add on a small quantity on one side
Colloid titanium surface conditioner 5 kilograms, (the most handy 50 ~ 60 DEG C of warm water dissolve Colloid titanium surface conditioner to fill up the water yield until completely dissolved
After build bath or add).When producing continuously, often process 500 ~ 1000, add 1 ~ 2 kilogram of Colloid titanium surface conditioner.PH value is less than
When 7.8, it is adjusted by Colloid titanium surface conditioner.When pH value is less than 7.5, colloidal titanium is precipitated, and surface adjusts lost efficacy, Ying Geng
Change.
After the long period processes, tank liquor meeting degradation, turn yellow, table adjusts effect to decline, and adjusts groove preferably with by table
Liquid continuous overflow discharging modes are added or to update all after some cycles.
The main operational principle of the present invention is as follows:
The hydrolysis generation of electronegative titanium phosphate colloid has highly active Ti (OH)4, it is attached in the way of physical absorption
Surface of the work, it has been filled up pitting and has formed the substantial amounts of netted nuclei of crystallization.When active layer surface contacts with Phosphating Solution, adsorb
The sodium ion of titanium phosphate colloid surface generates Hopeite grain with the zinc ion exchange in Phosphating Solution, and these crystal grain provide for phosphorus
Change the platform of layer epitaxially grown.The active site that formed in metal surface of Ti of these absorption number necessarily directly affect phosphating coat
Crystallite size.Colloid Ti ion is the least, and in unit are, the colloid Ti of absorption is the most, and phosphating coat crystallization is the most careful.
Having the beneficial effect that of Colloid titanium surface conditioner of the present invention:
(1) Colloid titanium surface conditioner has extremely strong anti-rust staining function.Workpiece can be greatly reduced and return rust rate, solve many
The knotty problem of Nian Laige pre-treatment manufacturer: i.e. workpiece easily returns rust after phosphatization.
(2) activity superelevation.The active function of Colloid titanium surface conditioner is the several times that general glue titanium table is adjusted, generally
Standing 30 days glue titaniums not settle, general table is adjusted between table timing 1-2 minute, and Colloid titanium surface conditioner only needs: iron and steel: 5 seconds left
The right side, zinc and kirsite: about 1 second, be substantially shorter phosphating time and reduce phosphatization temperature.
(3) the unequal defect of corrosion, increase crystalline substance that the quality of phosphating coat, elimination alkaline degreasing or acid pickling and rust removing cause are improved
Nuclear volume, improve the compactness of phosphating coat and corrosion stability, improve the outward appearance of phosphating coat.
(4) water quality is not selected.Colloid titanium surface conditioner contains water softener, so the most fastidious water quality during preparation, proportioning is dense
Degree 0.05%-0.2%.
(5) service life is long.This Colloid titanium surface conditioner activity declines slowly, the life-span is long, and general 1 kilogram of glue titanium surface adjusts
Agent can processing area be the workpiece of 2000 square metres, adjust with general table compared with, Colloid titanium surface conditioner integrated cost can reduce
1.5-2 again.
