Abstract

The invention relates to a coating with a new nano-scale material as a filler, which belongs to the field of coatings, and specifically relates to a preparation method of a nano-scale coating. In the present invention, the nano-scale and resin form chemical adsorption or chemical bonding, which can make the coating form The overall structure of the three-dimensional network has excellent adhesion, good impermeability, high corrosion resistance and some special functions. In the present invention, the nano-scale is not only a scale filler, but also a reinforcing agent and a modifying agent. The active bonds on its surface connect the scale and the resin in the form of chemical bonds to form a three-dimensional net-like overall structure. Utilizing the lamination effect of active scales can eliminate the internal stress of the coating, increase the anti-penetration ability of the coating, improve the adhesion and corrosion resistance of the coating, and achieve the purpose of endowing the coating with special functions and excellent performance.

Description

technical field [0001] The invention relates to a coating with a new nano-scale material as a filler, which belongs to the field of coatings, in particular to a preparation method of a nano-scale coating. technical background [0002] Dacromet paint and glass flake paint are several kinds of flake paint developed in our country in recent years. [0003] Dacromet (DACROMET) is the non-electrolytic zinc chromate coating. There is no waste water and waste discharge during the whole coating process. It is the best technology to replace the traditional electro-galvanizing hot-dip galvanizing that seriously pollutes the environment. [0004] Dacromet technology has a wide range of applications, not only for steel, iron, aluminum and their alloys, but also for sintered metals and special surface treatments. It involves many industries and trades, and the surface treated by Dacromet has high stability, heat resistance, moisture resistance and corrosion resistance. [0005] Althoug...
