Problems solved by technology

[0002] At present, there are many problems in paint coating production: For example, during the use of paint, a large amount of toxic and harmful organic solvents will be discharged into the atmosphere, and the environment will pay too much for it; long life
However, due to the characteristics of epoxy resin itself, epoxy powder coatings have poor weather resistance and wear resistance in practical applications, and the coating film is easy to pulverize, so it is not suitable for outdoor coating, which limits the application of epoxy powder coatings
At present, in the field of anti-...

Abstract

The invention discloses a heat-insulating corrosion-resistant powder coating material, and relates to the technical field of new materials. The preparation method comprises the following steps: firstly, modifying nano zinc powder with dopamine to prepare modified nano zinc powder, then treating potassium tetratitanate with acid liquor to prepare tetratitanate sol, mixing the modified nano zinc powder with the tetratitanate sol, preparing a heat-insulating filler blank under the action of a sodium dihydrogen phosphate solution, reacting the heat-insulating filler blank in a microwave oven for a period of time to obtain a pretreated heat-insulating filler blank, coating the pretreated heat-insulating filler blank with silicon dioxide sol to obtain a heat-insulating filler, mixing epoxy resin, the heat-insulating filler, a curing agent, a leveling agent and a silane coupling agent, tabletting, crushing, and sieving to obtain the heat-insulating and corrosion-resistant powder coating material. The heat-insulating corrosion-resistant powder coating material prepared by the invention has excellent heat-insulating property, corrosion resistance and toughness.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a thermal insulation and corrosion-resistant powder coating and a preparation method thereof. Background technique [0002] At present, there are many problems in the production of paint coating: for example, the paint will discharge a large amount of toxic and harmful organic solvents into the atmospheric environment during use, and the environment will pay too much for it; long-term lifetime. Environmental protection requirements are a major driving force for the development of powder coatings. As manufacturers are looking for ways to reduce product VOCs, powder coatings naturally replace liquid coatings in some areas. [0003] Epoxy powder coatings are thermosetting powder coatings developed in the last century. The film-forming material epoxy resin has excellent physical and mechanical properties, the coating film has good adhesion to the substrate, good electrical in...
