Abstract

The invention discloses an epoxy micaceous iron sealing agent for cold sprayed zinc. The sealing agent comprises a first component and a second component. The weight ratio of the first component to the second component is 6:1. The first component comprises, by weight, 10-20 parts of epoxy resin, 30-50 parts of micaceous iron oxide, 10-20 parts of talcum powder, 1-2 parts of aluminum powder, 1-5 parts of anti-settling agents, 0.1-0.2 part of defoaming agents and 10-35 parts of diluents. The second component is a polyamide epoxy curing agent. The invention further discloses a preparation method of the epoxy micaceous iron sealing agent for cold sprayed zinc. The sealing agent is applied to a cold sprayed zinc three-coating system to serve as an intermediate paint sealing agent, can be applied to an epoxy zinc-rich primer and serves as a sealing agent in an inorganic zinc-rich primer system. The epoxy micaceous iron sealing agent for the cold sprayed zinc is used for increasing adhesive force of the cold sprayed zinc, avoids the sagging phenomenon, and facilitates construction. When the sealing agent is used, bubbles are not easily generated, and the defoaming effect is good.

Description

technical field [0001] The invention relates to an epoxy mica-iron sealant for cold-spraying zinc and a preparation method thereof. Background technique [0002] In order to increase the service life of heavy-duty coatings, reduce the difficulty of construction, and improve the appearance of the paint film, intermediate sealers are often added to traditional zinc-rich systems. Generally, the PVC of epoxy mica-iron sealers is too high, and a large amount of thinner needs to be added during construction. , pollute the environment, and it is easy to generate bubbles for a relatively loose primer such as zinc-rich, and it is difficult to defoam, resulting in many problems with the performance of the paint film (insufficient adhesion) and the appearance, while the epoxy with too low PVC Although the cloud iron sealant has good leveling properties, it is easy to produce a sagging effect on vertical workpieces, which increases the difficulty of construction. This disadvantage is es...
