Description
Technical Field
The utility model belongs to the technical field of the coating technique and specifically relates to a long-term anti rust primer of high solid content epoxy.
Background
High solids epoxy primers are one of the important developments in modern coatings. The epoxy resin has excellent film forming property and adhesive force, has good corrosion resistance and permeability resistance to various media, can be well mixed and dissolved with various resins, fillers and additives, and can be one of main film forming materials of the anticorrosion primer, but because the adhesive force of the epoxy resin and a base material is poor, the coating layer can crack and fall off due to the poor adhesive force of the coated metal exposed in a high-humidity environment or a solution for a long time, and the surface of the metal is exposed to rust, so that the wet adhesive force of the high-solid epoxy primer needs to be enhanced, and the antirust time of the primer can be effectively prolonged.
A plurality of studies at home and abroad show that the nano particles are used for modifying the epoxy, so that the adhesive force of the epoxy resin can be effectively improved, the toughness, the corrosion resistance, the surface performance and the like of the coating can be improved, and the technical problem of the performance reduction of the epoxy resin is solved.
