Abstract

The invention discloses glass-flake mastic resin special for flue gas desulfurization and belongs to the technical field of chemical coating. The glass-flake mastic resin comprises matrix resin, modified glass flakes, modified sepiolite, a coupling agent, a defoaming agent and an accelerant, wherein the matrix resin is formed by phenolic aldehyde epoxy type vinyl ester resin and modified unsaturated polyester resin. A preparation method of the glass-flake mastic resin includes: mixing the matrix resin and the modified sepiolite, shearing and dispersing to obtain a dispersed material, adding the dispersed material, the modified glass flakes, the coupling agent, the defoaming agent and the accelerant into a kneading machine, kneading, and performing vacuum defoaming, discharging and packaging to obtain the glass-flake mastic resin special for flue gas desulfurization. The prepared glass-flake mastic resin is excellent in toughness, thermal shock resistance and corrosion resistance.

Description

technical field [0001] The invention discloses a special glass flake cement for flue gas desulfurization, which belongs to the technical field of chemical coatings. Background technique [0002] In recent years, flake mastic coatings, especially vinyl ester resin glass flake mastic coatings (hereinafter referred to as "flake mastic"), have been widely used in the chemical coating industry. In the early years, it was mainly used in the lining anti-corrosion of flue gas desulfurization FGD devices, which made the majority of downstream anti-corrosion engineering fields realize the advantages and benefits of glass flake cement. [0003] With the in-depth development of the market, glass flake cement is no longer limited to the field of FGD, and has also been well promoted in many other anti-corrosion engineering fields. But problems also follow. Because the majority of users do not have a deep understanding of the principle of glass flakes, if the manufacturing technology and ...
