Problems solved by technology

[0003] At present, the functional coating materials widely used in the field of equipment support can only solve individual problems in anti-corrosion, heat insulation, and camouflage and stealth. Their functions are relatively single, and their effects are general, and their compatibility is poor. Protection effect, it is difficult to provide long-term protection for equipment
In addition, most of the existing coating materials are still solvent-based, which is potentially harmful to the coating environment and construction personnel, and does not meet the requirements of current environmental protection policies
[0004] In the patent CN104073085A disclosed "anti-visible light and near-infrared detection fluorocarbon optical camouflage coating and its preparation method", the coating only has visible light and near-infrared camouflage performance, and cannot meet the comprehensive protection of thermal infrared, anti-corrosion, and heat insulation. need
Patent CN102585631A provides "a water-based camouflage paint and its preparation method". Although the paint is a water-based product, it also only has the function of resisting visible light and near-infrared detection. The anti-corrosion effect is general, and it cannot adapt to high temperature, high humidity and high salt. Harsh environment with fog and high ultraviolet rays

Abstract

The invention discloses a waterborne anti-corrosion heat insulation camouflage painting composite coating which sequentially comprises waterborne graphene heavy-duty anti-corrosion priming paint, waterborne heat insulation intermediate paint and waterborne camouflage painting finishing paint from inside to outside. The waterborne graphene heavy-duty anti-corrosion priming paint is provided with anepoxy zinc-rich system added graphene, an anti-corrosion function is achieved by labyrinth effects of the graphene and 'zinc-alkene' electrochemical synergy mechanisms, the heat insulation intermediate paint barriers dept transfer of heat by the aid of low-heat-conduction particles, so that relatively stable inner temperature of a base material is kept, the camouflage painting finishing paint isprovided with high-weather-resistant acrylic acid polyurethane, and different tinting pigments and heat reflection particles are matched, so that visible light-infrared camouflage and sunlight reflection are achieved. The composite coating is simple in composition structure and low in VOCs (volatile organic compound) content, meets national environment protection requirements and can be applied tointegrated protection requirements of industries such as military vehicles, equipment and launchers for corrosion protection, heat insulation and visible light-infrared camouflage and stealth.
