Abstract

The invention discloses a room-temperature rapid-curing coating material with a high-infrared-radiation coating as a cured product, and a preparation method thereof, wherein the curing coating material is prepared by mixing and stirring an epoxy resin, a high-infrared-emissivity substance, an amine curing agent, imidazole, a coupling agent, an accelerant, a surfactant and a solvent, wherein the mixed solution is good in environmental protection property, has proper working life and paint film initial curing time at a room temperature, and is suitable for rapid curing at a room temperature. According to the invention, with the application of the curing coating material to perform surface treatment on parts, the defects of too long or too short working life and too long or too short initialcuring time of the coating materials in the prior art are overcome.

Description

technical field [0001] The invention belongs to the field of rapid curing compositions at room temperature, and in particular relates to a rapid curing coating at room temperature whose cured product is a high infrared radiation coating and a preparation method thereof. Background technique [0002] Infrared radiation coatings are used in multiple parts of high-speed rotating machines, and their main function is to enhance the radiation and heat dissipation capabilities of parts through the formed high infrared radiation coatings. With the increase in the production batch of high-speed rotating machines and the adjustment of the production process, the current infrared radiation coatings cannot fully meet the actual production needs in terms of working hours and work efficiency. Curing, at the same time, coating performance and process performance, etc. meet the needs of the coating. Contents of the invention [0003] The present invention is proposed in order to overcome...
