Abstract
The present invention relates to a kind of automobile that is used for, household electrical appliance, shell steel plates such as various instrument carry out parkerized phosphatization liquid and manufacture method thereof.The present invention is by phosphoric acid, nitric acid, zinc oxide, raw materials such as catalyzer nickelous nitrate and water react under normal pressure and form, use temperature of the present invention is low, phosphatization liquid use temperature is low 10-20 ℃ than before, uses the present invention, can be in 120-150 film forming in second, film is fine and close and thin, lacquer class and oils are had stronger adsorptive power, and therefore, the present invention can use in the large-scale pipeline operation.
Description
The present invention relates to a kind of automobile that is used for, household electrical appliance, various instrument, the shell steel plate of instrument etc. carries out parkerized phosphatization liquid.
Various automobiles, tractor, refrigerator, washing machine, shell steel plates such as instrument are in order to be appearance paint light and strong adhesion, generally all will spray paint pre-treatment, i.e. bonderizing of these shell steel plates, but the etching solution treatment temp of using is higher at present, phosphating time is long, can not be applicable to modernized streamline operration, and of poor quality, the phosphatization thickness, sediment is many.Therefore press for a kind of liquid of phosphatization preferably.The phosphatization liquid that provides a kind of quality higher is provided the object of the invention.Use temperature of the present invention is lower, and phosphatize phosphate coat is thin fine and close, and sediment is few, and film formation time is short.
The present invention is by phosphoric acid, and nitric acid, zinc oxide, catalyzer, nickelous nitrate and water react under normal pressure and forms, and its prescription (grams per liter) is:
Phosphoric acid 5-15
Nitric acid 3-10
Zinc oxide 3-15
Catalyzer 0.01-2
Nickelous nitrate 0.3-3
Above-mentioned catalyzer can be a Sodium Nitrite, and remaining is a water in every liter.
The production technique of this phosphatization liquid is: (1) at first adds phosphoric acid in reactor, nitric acid, zinc oxide, water, stir then up to there not being solid matter (2) aforesaid liquid to be injected in second reactor, add catalyzer, nickelous nitrate, water then, stir the liquid of 2-5 hour (3) the second reactor internal reaction being crossed and inject settling bath, be finished product of the present invention through precipitation pit internal upper part clear liquid.
Embodiment:
Phosphoric acid (84%) 9.04
Nitric acid (69%) 7.04
Zinc oxide (98%) 5
Sodium Nitrite 0.01
Nickelous nitrate 0.5
All the other are water
According to above-mentioned technical process, can produce this phosphatization liquid.
The present invention is a low temperature, the low quick slim zinc phosphide liquid of slag, and low 35-40 ℃ of use temperature, other phosphatization liquid is low 10-20 ℃ at present.The loose and few 1-3g/t of sediment, the fast 120-150 of phosphatization liquid of the present invention phosphatize phosphate coat second is thin fine and close, solidity to corrosion reached more than 90 hours, adsorptive power to lacquer class and oils is good, can be widely used in automobile, tractor, refrigerator, the bottom of the shell steel plate oil paint of washing machine and various instrument, and use on the convenient extensive modernized streamline.
Claims (3)
1, a kind of new phosphide liquid is characterized in that it is to be reacted under normal pressure by phosphoric acid, nitric acid, zinc oxide, catalyzer, nickelous nitrate water to form, and the prescription of this phosphatization liquid is: (grams per liter)
Phosphoric acid 5-15
Nitric acid 3-10
Zinc oxide 3-15
Catalyzer 0.01-2
Nickelous nitrate 0.3-3
Water surplus
2,, it is characterized in that catalyzer can be a Sodium Nitrite as the described new phosphide liquid of claim (1).
3, as the described new phosphide liquid of claim (1), its feature in the production technique of this phosphatization liquid is:
A, in reactor, add phosphoric acid, nitric acid, zinc oxide, water, stir then, up to there not being solid matter.
B, aforesaid liquid is injected in second reactor, adds catalyzer, nickelous nitrate, water then and stirred 2-5 hour
C, the liquid in second reactor is injected in the settling bath, the clear liquid on post precipitation top is this phosphatization liquid finished product.
