Problems solved by technology

[0003] At present, the passivation treatment agents used in the passivation process generally contain harmful substances such as chromic acid, potassium dichromate, sodium dichromate, sodium molybdate or nitrite, which seriously affect the physical and mental health of operators and the environment. At the same time, it needs to be heated in the process of processing, which consumes a lot of energy

Embodiment 1

[0016] The raw materials and mass percentages used are as follows:

[0017] Phosphoric acid 8~12%

[0018] Zinc oxide 1~2%

[0019] Sodium tripolyphosphate 1~4%

[0020] Nickel nitrate 1~3%

[0021] JN-30 silica gel 4~6%

[0022] Water-soluble epoxy resin 4~6%

[0023] Deionized water balance.

[0024] A method for producing the above-mentioned new type of electrogalvanizing coating agent passivation treatment agent is characterized in that it is carried out as follows: adding deionized water calculated and weighing into the reactor, heating to 45°C, and turning on the stirrer to control the speed of 60 Rpm / min, then add the calculated weighing phosphoric acid, zinc oxide, sodium tripolyphosphate, nickel nitrate, JN-30 silica gel and water-soluble epoxy resin to the reaction kettle in sequence, and stir until the mixture is uniform while adding, and wait for the ...

Embodiment 2

[0027] The raw materials and production methods are the same as in Example 1, except that the raw materials and mass percentages are as follows:

[0028] Phosphoric acid 12%

[0029] Zinc oxide 1%

[0030] Sodium tripolyphosphate 4%

[0031] Nickel nitrate 1%

[0032] JN-30 silica gel 6%

[0033] Water-soluble epoxy resin 4%

[0034] Deionized water balance.

[0035] The working fluid is prepared according to the mass percentage concentration of 3.8%, and the PH value is controlled from 1 to 1.5pt. The steel workpiece is electrogalvanized and immersed in the passivator for 30s at room temperature to achieve the technological purpose. The hot fog test can reach more than 72 hours.

Abstract

The invention discloses a novel electroplateing zinc layer agent passivating agent. The novel electroplateing zinc layer agent passivating agent comprises following raw materials, by mass, 8 to 12% of phosphoric acid, 1 to 2% of zinc oxide, 1 to 4% of sodium tripolyphosphate, 1 to 3% of nickel nitrate, 4 to 6% of JN-30 silica gel, 4 to 6% of water soluble epoxy resin, and the balance deionized water. A production method comprises following steps: weighed deionized water is delivered into a reaction vessel, and is heated to 45 DEG C; a stirrer is turned on, and rotating speed is controlled to be 60r / min; weighed phosphoric acid, zinc oxide, sodium tripolyphosphate, nickel nitrate, JN-30 silica gel, and water soluble epoxy resin are delivered into the reaction vessel successively with stirring until uniform mixing is realized; and an obtained solution is cooled to room temperature, and is collected and packaged.

Description

Technical field [0001] The invention relates to a metal passivation treatment agent, in particular to a new type of electrogalvanization coating agent passivation treatment agent which is non-toxic and harmless, does not have any impact on operators and the environment, does not require heating during the treatment process, and saves energy. production method. Background technique [0002] Metal passivation treatment is an important part of metal surface engineering. The essence of metal passivation treatment is to carry out a chemical reaction in the corresponding treatment solution of specified process conditions and process parameters to form a chemical conversion film on the surface, also known as passivation membrane. The passivation film must not only give the metal surface a certain degree of protection and decoration, but also prevent the corrosive medium in the atmosphere from corroding the metal surface. The more important function is to meet the needs of small-scale p...
