Abstract

The invention belongs to the technical field of coatings, and particularly discloses a solvent-free temperature-resistant epoxy phenolic anticorrosive coating and a preparation method thereof. The preparation method comprises the steps that resin, a wetting dispersant, a toughening diluent, filler, a curing agent and other components are screened or modified, and viscosity reduction is conducted on the coating; and finally the solvent-free epoxy phenolic aldehyde temperature-resistant anticorrosive coating with the operable time of more than 2 hours is obtained. The environment-friendly requirement of VOC is met and the coating construction is facilitated, and the production efficiency is improved. Meanwhile, the glass transition temperature of the epoxy phenolic aldehyde coating is further increased, the temperature resistance of the coating is enhanced, and the prepared coating has good adhesive force, flexibility and impact resistance. Good balance between the mechanical property and the temperature-resistant and chemical-resistant properties of a paint film is obtained.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a solvent-free temperature-resistant epoxy phenolic anticorrosion coating and a preparation method thereof. Background technique [0002] The difficulty of solvent-free epoxy phenolic coatings is that the viscosity of epoxy phenolic resin is too high and the fluidity is very poor, so it is difficult to process into solvent-free epoxy phenolic coatings. The volume solid content of existing phenolic coatings is generally 50-60%. Such products have low viscosity and easy construction, but have high VOC content and low film thickness at one time, which are not suitable for the requirements of efficient and environmentally friendly coating. [0003] Solvent-free phenolic epoxy coatings have extremely low VOC emissions, but have a high viscosity, and the operating time is less than 30 minutes. When spraying, it is necessary to strictly control the spraying time, or use mul...
