Abstract
The invention relates to the technical field of automobile part machining, in particular to treatment liquid for phosphating before painting of an automobile door. The treatment liquid is prepared from 10 parts of maleic anhydride, 6 parts of zinc oxide, 5 parts of phosphoric acid, 5 parts of nitric acid, 0.5 part of aminocarboxylic acid, 5 parts of nickel nitrate and 70 parts of water. According to the treatment liquid adopted in the phosphating method, the formula design of the treatment liquid is novel and reasonable, and especially, a small amount of the aminocarboxylic acid is added so that the treatment efficiency of the treatment liquid can be remarkably improved. The binding force between a painting film layer and the automobile door can be remarkably improved, and the corrosion resistance of the automobile door can be remarkably improved.
Description
Technical field
The present invention relates to automobile component processing technique field, specifically relate to a kind of for treatment solution parkerized before automobile door coating.
Background technology
Arrangements for automotive doors, before the steps such as application, needs to carry out bonderizing to it, to form phosphatize phosphate coat, thus improves the erosion resistance on arrangements for automotive doors surface.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of for treatment solution parkerized before automobile door coating, for achieving the above object, present invention employs following technical scheme:
A kind of for parkerized treatment solution before automobile door coating, be made up of 10 parts of maleic anhydrides, 6 parts of zinc oxide, 5 parts of phosphoric acid, 5 parts of nitric acid, 0.5 part of aminocarboxylic acid, 5 parts of nickelous nitrates and 70 parts of water.
Beneficial effect of the present invention shows:
1), the treatment solution that uses in method for bonderizing, its formulating of recipe is novel, rationally, particularly with the addition of a small amount of aminocarboxylic acid, can significantly improve the processing efficiency for the treatment of solution.The bonding force between application rete and arrangements for automotive doors can be significantly improved, and significantly improve the erosion resistance of arrangements for automotive doors.
2), the preparation method for the treatment of solution, by progressively adding and choose reasonable order of addition(of ingredients), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, the bonderizing efficiency for the treatment of solution is significantly improved.
3), by the formula of appropriate design treatment solution and the preparation method for the treatment of solution, thus the phosphatize phosphate coat realizing arrangements for automotive doors surface is formed fast, and thickness is even, then improves the recycling degree of arrangements for automotive doors, improves the quality of arrangements for automotive doors product.
Embodiment
Below with reference to embodiment, the present invention is described in detail.But; embodiment content is only citing made for the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
One, the composition for the treatment of solution
10 parts of maleic anhydrides, 6 parts of zinc oxide, 5 parts of phosphoric acid, 5 parts of nitric acid, 0.5 part of aminocarboxylic acid, 5 parts of nickelous nitrates and 70 parts of water.
Two, the preparation method for the treatment of solution is:
First in container, add 5 parts of nitric acid, 10 parts of maleic anhydrides and 30 parts of water, stir 5 minutes; Then slowly add 5 parts of phosphoric acid, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 6 parts of zinc oxide and 20 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of aminocarboxylic acid, limit edged stirs, and stirs 10 minutes after interpolation; Finally add 5 parts of nickelous nitrates and 20 parts of water fast, stir 10 minutes.
Three, for treatment solution parkerized before automobile door coating, step is as follows:
Step 1., the greasy dirt on erasing arrangements for automotive doors surface, then use ethanol to clean 5 minutes, then to rinse with clear water;
Step 2., use sand paper polished in arrangements for automotive doors surface, then adopt the sodium hydroxide solution alkaline etching of 0.5mol/L to remove the oxide film on its surface, rinse with clear water after alkaline etching;
Step 3., arrangements for automotive doors put into the treatment solution being heated to 40 DEG C in advance and soaks 5 minutes;
Step 4., pull out rear water rinse until the pH value of water returns to neutrality;
Step 5., put into constant temperature oven dry 1 hour, constant temperature in-furnace temperature is 100 DEG C.
