Problems solved by technology

[0002] Post-plating treatment and pre-plating treatment occupy an extremely important position in the metal surface plating work. Many surface-plated products have defects that are often caused by improper pre-plating treatment or post-plating treatment. Knowledge about pre-plating treatment There are more detailed introductions in general electroplating professional books and periodicals, but there is a lack of systematic discussion on post-plating treatment.

Embodiment 1

[0008] Example 1: 1 liter of the corrosion-resistant coating sealer contains the following substances: 2 g of urea imidazole dione, 1 g of polydimethylsiloxane, 3 g of polyquaternium-10, 1 g of acrylic acid polymer, promethacine Amino acid 1g, methylisothiazolinone 1g, the balance water.

[0009] Dissolve 30ml of the above sealing agent in 1 liter of water and stir evenly; wash the plated workpiece with water and put it in the sealing agent at room temperature to seal for 60 seconds; take out the workpiece, wash it with running water, and put it in an oven to dry.

Embodiment 2

[0011] 1 liter of the corrosion-resistant coating sealer contains the following substances: urea imidazole dione 2.5g, polydimethylsiloxane 1.5g, polyquaternium-10 6.5g, acrylic acid polymer 3g, methacine proline 2 g of acid, 2 g of methylisothiazolinone, and the rest of water.

[0012] Dissolve 20ml of the above sealing agent in 1 liter of water and stir evenly; wash the plated workpiece with water and put it in the sealing agent at room temperature to seal for 35 seconds; take out the workpiece, wash it with running water, and dry it in an oven.

Embodiment 3

[0014] 1 liter of the corrosion-resistant coating sealant contains the following substances: urea imidazole dione 3g, polydimethylsiloxane 2g, polyquaternium-10 10g, acrylic acid polymer 5g, methacine proline 3g, Methylisothiazolinone 3g, balance water.

[0015] Dissolve 10ml of the above sealing agent in 1 liter of water and stir evenly; wash the plated workpiece with water and put it in the sealing agent at room temperature to seal for 10 seconds; take out the workpiece, wash it with running water, and put it in an oven to dry.

Abstract

The invention discloses a corrosion-resistant coating sealing agent. The corrosion-resistant coating sealing agent with the volume of 1 liter comprises the following substances by weight: 2-3g of imidazole diketone urea, 1-2g of polydimethylsiloxane, 3-10g of polyquaternium-10, 1-5g of acrylic polymers, 1-3g of methylproline, 1-3g of methylisothiazolinone and the balance of water. The method comprises the following steps: adding 10-30ml of sealing agent into each liter of water, and uniformly stirring; washing the coated workpiece, putting the workpiece into the sealing agent at room temperature to seal for 10-60 seconds; and taking the workpiece out, washing by using percolating water, and drying in a drying box. The sealing agent is suitable for galvanization, nickel plating, chromeplating, copper plating, silver plating, gold plating, the neutral salt mist test resistance can reach over 72 hours, and the sealing agent is small in amount, low in cost, easy to operate and easy to maintain.

Description

technical field [0001] The invention relates to a corrosion-resistant coating sealing agent, in particular to the sealing of electroplating and surface treatment coatings. Background technique [0002] Post-plating treatment and pre-plating treatment occupy an extremely important position in the metal surface coating work. Many surface-coated products have defects that are often caused by pre-plating treatment or improper post-plating treatment. Knowledge about pre-plating treatment There are more detailed introductions in general electroplating professional books and periodicals, but there is a lack of systematic discussion on post-plating treatment. The post-plating treatment is mainly to improve the corrosion resistance of the coating or to maintain the original characteristics of the coating, among which the most important post-plating treatment is hydrogen removal treatment, passivation treatment and sealing treatment.
