Problems solved by technology

The importance of the coating on the liquid surface lies in: 1. In electrolysis, the fluctuation of the electrolyte surface causes a thin layer of electrolytic zinc to be deposited on the liquid surface. This thin layer of zinc causes great difficulties in the zinc stripping work, because the zinc layer The thinner it is, the more difficult it is to strip zinc
2. If there is no coating on the liquid surface, the zinc on the surface of the liquid surface and the zinc on the surface of the pole plate are connected together, then it is almost impossible to take mechanical stripping of zinc, because there is no cutting edge for the zinc deposited on the cathode plate entry point

Abstract

The invention relates to an epoxy vinyl ester micro compound resin and preparing method thereof. The resin is characterized by that epoxy vinyl ester micro compound resin mainly comprises epoxy vinyl ester resin, quartz sand, dispersant, defoaming agent and leveling agent. The preparing method of epoxy vinyl ester micro compound resin comprises the following step: (1) Weighting raw materials according to claim 2 formula; (2) mixing and stirring raw materials after the raw materials are added into mixing tank; (3) adding the raw materials into high-speed dispersing machine for dispersion; (4) adding the raw materials into grinding miller for grinding; (5) packaging all raw materials in different packages and placing them in cool and dry place for later use. In the preparing method, high-speed dispersing can mix the chemical materials with quartz powder completely and evenly, grinding can open the particles of original resin to make the particles form a new combination with the high-speed dispersed mixture which is added later, in order to form epoxy vinyl ester micro compound resin.

Description

[0001] 【Technical field】 [0002] The invention relates to an epoxy vinyl ester microcrystalline composite resin and a preparation method thereof. [0003] 【Background technique】 [0004] It is used for the surface coating of the aluminum cathode plate used in zinc electrolysis, and the distance from the pole beam to the electrolyte is called the liquid surface. For a long time, zinc electrolysis plants both at home and abroad have wanted to coat a coating that can isolate zinc electrolytic deposition on the liquid surface of the cathode plate, but there is no such thing. Because this kind of coating should have: 1. The viscosity should be low. 2. The shrinkage ratio is smaller. 3. The solution does not contain air bubbles. 4. Resistance to acid corrosion below 40% and long-term temperature resistance above 50°C. 5. Adhesive and traction with aluminum plate, no layering. 6. It has a certain hardness (Bako hardness above 45). Because the specialization is too strong and th...
