Problems solved by technology

[0002] At present, there are many problems in the comprehensive surface protection performance of the armored equipment of the Chinese Army, mainly in the following aspects: First, when the equipment is used for training and use in the marine environment, the external corrosion of the equipment is serious, resulting in the rusting or damage of the external parts of the equipment and the vehicle body. The phenomenon of paint film peeling off on the surface has a certain impact on the technical performance of the equipment, bringing many problems and difficulties to the use, management and maintenance of the equipment, and also increasing the workload and expenditure of equipment maintenance. The second is that when the equipment is used for training in summer, the temperature inside the vehicle is high (above about 50°C), which consumes a lot of physical energy for the occupants, and also accelerates the aging and damage of rubber products and electrical components in the vehicle, reducing the service life of the equipment. , seriously affected the technical performance of the equipment and the combat capability of the troops
The third is that the equipment has low stealth protection performance and anti-reconnaissance capability, and low battlefield survivability
[0003] In view of the above-mentioned many problems, there are many functional coatings in the society to solve the above-mentioned problems respectively, but these functional coatings have single functions. Layers are applied multiple times, and most paints will reduce their own protective effect when mixed, which greatly reduces the effectiveness of the paint and cannot provide long-term effective protection for the equipment. At the same time, these various functions The effect of the coating is average. For example, when the functional coating provided by a domestic company is used in the cooling experiment on the armored vehicle after coating, it can only reduce the temperature inside the armored vehicle by 2-4°C, and the infrared signal basically does not change. This is basically the case in actual combat. It can be ignored, so it is impossible to effectively improve the comfort of the equipment and reduce the infrared signal of the equipment; in addition, the existing coatings also have poor performance in anti-corrosion and other effects, so it is urgent to develop a multifunctional composite coating to solve the problem. There are many problems in the comprehensive protection performance of the surface of our military equipment
