Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a high-viscosity two-component epoxy paint. Background technique [0002] Epoxy resin has a bonding effect on various metal materials, non-metal materials, thermosetting polymer materials, etc. As a new type of coating, epoxy coating has easy-to-obtain raw materials, easy preparation, simple process, wide use temperature, low toxicity, strong adaptability, no volatile solvent, can be cured without pressurization, and has a low curing shrinkage rate. Low, good environmental resistance, widely used in many fields. However, the existing epoxy coating has high crosslinking density after curing, and has the problems of large internal stress, brittle texture, poor fatigue resistance, poor adhesion, and low tensile bond strength. The invention provides a high-viscosity two-component epoxy paint with good adhesion, good tensile bonding strength, good alkali resistanc...
