Abstract

The invention provides a zinc plating water-based blocking agent. The zinc plating water-based blocking agent comprises, by weight, 10 to 30 parts of acrylic resin, 0.1 to 0.4 part of sulfur silicane,0.1 to 0.4 part of an amino silicane, 0.05 to 0.4 part of a surfactant, 0 to 6 parts of ethanol, 0.1 to 0.4 part of a pore sealing agent, and 0 to 20 parts of water, wherein the amount of ethanol andthe amount of water are not 0 at the same time. The invention also provides a preparation method of the zinc plating water-based blocking agent, and applications of the zinc plating water-based blocking agent as a blocking agent in zinc plating blocking processing. The zinc plating water-based blocking agent is capable of realizing high combination with plating layers, and is excellent in wear resistance and corrosion resistance; the preparation method is simple; operation is convenient; and the zinc plating water-based blocking agent is green and nontoxic.

Description

technical field [0001] The invention relates to a galvanized water-based sealant and a preparation method and application thereof, belonging to the field of material technology. Background technique [0002] At present, the property loss caused by corrosion has accounted for more than 1.5% of the gross national product. Among them, steel corrosion not only causes a lot of waste of materials, but also causes equipment failures such as running, leaking, dripping, and leaking. Thereby causing fire, explosion and other accidents. [0003] As an anodic coating, zinc has poor corrosion resistance and is prone to discoloration due to oxidation, so passivation treatment is required to enhance its corrosion resistance; however, for products with high performance requirements, only passivation treatment is far away. If it is far from enough, it must be sealed after passivation to improve the corrosion resistance and decoration of the product. [0004] In the prior art, mainstream ga...
