Description

Technical Field

[0001] The utility model relates to the technical field of coatings, in particular to a high-viscosity AB component coating spraying device. Background Art

[0002] High viscosity AB component coatings are a type of material commonly used for surface coating and protection, where AB represents two different components. Usually, these components undergo a cross-linking chemical reaction after mixing to form a cured paint film. This type of coating is widely used in the automotive, aerospace, construction and other fields, and is highly favored for its excellent wear resistance, corrosion resistance, high temperature resistance and other properties.

[0003] Due to the high viscosity of high-viscosity AB component coatings, traditional spray systems may have difficulty spraying the coating evenly on the target surface, resulting in poor coating quality. The current common coating method uses heating to reduce the viscosity of the components to achieve smooth component delivery, mixing and atomization. However, high temperatures will promote the cross-linking reaction of coating components, accelerate coating curing, cause the coating to cure too quickly, and cause coating defects such as cavitation, pinholes and adhesion failure.
