An epoxy resin coating with corrosion resistance and excellent mechanical properties

Abstract

The invention discloses a corrosion-resistant epoxy resin paint with excellent mechanical properties. The epoxy resin paint comprises a component A and a component B. The component A comprises the following raw materials in parts by weight: 25-35 parts of bisphenol A epoxy resin, 20-40 parts of E-51 epoxy resin, 5-15 parts of amino resin, 1-3 parts of microcrystalline wax, 1-2 parts of dibutyl ester, 10-18 parts of modified bamboo powder, 1-3 parts of silane coupling agent, 2-8 parts of soot, 10-16 parts of activated carbon powder, 0.5-1.2 parts of anti-settling agent, 0.5-1.2 parts of leveling agent, 0.5-1.2 parts of dispersing agent and 0.5-1.2 parts of defoaming agent. The component B is prepared from the following raw materials in parts by weight: 15-35 parts of butanol, 5-15 parts of xylene, 10-20 parts of polyether diamine and 10-20 parts of trimethyl hexamethylenediamine. The weight ratio of the component A to the component B is 10:(1-3). The epoxy resin paint has the advantages of high adhesive force, favorable corrosion resistance and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of epoxy coatings, in particular to an epoxy resin coating with corrosion resistance and excellent mechanical properties. Background technique [0002] Most of the large-scale high-temperature liquid storage tanks or pipelines in my country currently use metal pipes. Since the pipe walls are basically in a humid or high-temperature state, linings are generally added to the inner walls of these tanks and pipes, or paint is directly applied to the inner walls. In order to improve the surface smoothness and anti-corrosion performance of these equipment, prolong their service life. The lining protection method often used for the inner wall of liquid storage tanks or pipelines is to use composite materials, but the process is complicated, the cost is high, and the popularity is low. At present, it is more common to use suitable paint to form a protective coating on the surface of the inner wall. It is simple, eff...

The lining protection method often used for the inner wall of liquid storage tanks or pipelines is to use composite materials, but the process is complicated, the cost is high, and the popularity is low. At present, it is more common to use suitable paint to form a protective coating on the surface of the inner wall. It is simple, effective, and low in cost. Traditional epoxy coatings have relatively high requirements on the surface of the substrate. In some harsh environments, the smoothness, adhesion and corrosion resistance of epoxy coatings cannot meet the requirements for use. Traditional environmental Oxygen coatings cannot meet the requirements of the above fields
