Abstract

The invention provides an epoxy resin coating and a preparation method and application thereof. The coating comprises a component A and a component B which are independently packaged, wherein the component A comprises the following materials in parts by weight: 36-40 parts of epoxy resin, 3.3-3.6 parts of packing such as micron-order Ti-Al alloy powder, 1.3-1.4 parts of pigment, 13.3-21 parts of solvent and assistants such as 0.6-1 part of degassing agent, 0.6-1 part of curing accelerator and 0.6-1 part of dispersing agent; and the component B comprises 36-40 parts of curing agents. The process of preparing the micron-order Ti-Al alloy powder comprises the following two steps: performing plasma rotation electrode atomization and performing ball-milling and refining. The coating is mainly applied to a metal workpiece anticorrosive coating. The coating disclosed by the invention can effectively improve the anticorrosive properties of metal workpieces and is low in cost, simple in production process, low in equipment requirement, high in quality, uniform in components and easy for industrialization.

Description

technical field [0001] The invention relates to an epoxy resin coating, in particular to an epoxy resin coating using micron Ti-Al alloy powder as a filler, a preparation method and application thereof. Background technique [0002] Corrosion refers to the phenomenon that the surface of an object is damaged by a chemical reaction or an electrochemical reaction with the surrounding medium, mainly referring to metal corrosion. Metal corrosion is not only a huge waste, but also brings serious losses to the national economy and people's lives and property. Therefore, it is of great significance to the development of the national economy to study the corrosion protection methods of metals to control the corrosion of metals and reduce the losses caused by corrosion. Metal corrosion damage generally has the following two characteristics: 1. The damage always starts from the metal surface, and then goes deep into the deep layer quickly or slowly; Affect the continuous use and safe...
