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

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.

Description

technical field [0001] The invention specifically relates to an anti-corrosion, heat-insulating, camouflage and stealth composite coating, which belongs to the field of new chemical materials. Background technique [0002] With the rapid development of the military industry, the application of high-tech in modern warfare is becoming more and more extensive, the replacement of cutting-edge weapons and equipment is getting faster and faster, the degree of intelligence, automation and systematization is getting higher and higher, and the requirements for equipment performance are also increasing. It is of great strategic significance to develop a protection system that integrates anti-corrosion, heat insulation, camouflage and stealth functions. [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...
