Problems solved by technology

[0005] However, coatings used on aircraft and other targets must have good lubricating oil resistance, because various types of aircraft will inevitably seep from the internal lubricating oil to the aircraft surface due to the severe vibration of the engine during high-speed flight. Leakage, which will have a significant impact on the comprehensive performance of the surface coating, and even make the functional properties of the surface coating invalid
Therefore, it is particularly urgent to carry out research on the lubricating oil resistance of functional coatings on aircraft surfaces; however, there is no report on the lubricating oil resistance of composite coatings with low near-infrared reflection and low emissivity of 8-14 μm; therefore , carrying out research on the lubricating oil resistance of such special functional coatings has important practical significance for improving the comprehensive performance of infrared and laser compatible stealth coating materials

Abstract

The invention relates to a preparation method of compatible paint and coating with a high lubricating oil resisting performance, low near-infrared reflection and 8mum-14mum low emissivity. The preparation method comprises the following steps: taking Al powder and Sm2O3 powder as functional pigments and taking sodium polycarboxylate as a dispersant and butyl acetate as a diluting agent; dispersing the raw materials by adopting a paint high-speed dispersion machine; adding a polyurethane (PU) adhesive, sericite, a silane coupling agent and a curing agent; after sufficiently stirring and dispersing, adjusting the viscosity to be 16s-20s by utilizing a proper amount of the diluting agent; filtering to obtain the compatible paint with the high lubricating oil resisting performance, the low near-infrared reflection and the 8mum-14mum low emissivity; then coating the surface of a pre-treated base plate with the paint by adopting a spraying method; and naturally drying for 3h-5h and drying at 50 DEG C-60 DEG C for 24h, so as to obtain the compatible coating with the high lubricating oil resisting performance, the low near-infrared reflection and the 8mum-14mum low emissivity. The compatible paint provided by the invention has relatively low infrared emissivity and 1.06mum near-infrared reflectivity and is coated on surfaces of equipment including fighter planes, guided missiles, warships, tanks, chariots and the like, and has infrared and laser and invisible effects and prominent lubricating oil resisting performance.

Description

technical field [0001] The invention relates to a coating and a preparation method of a coating compatible with high lubricating oil performance, low near-infrared reflection and low emissivity of 8-14 μm, and belongs to the technical field of fine chemicals. Background technique [0002] In recent years, with the rapid development of infrared thermal imaging technology, laser detection and guidance technology, it poses a great threat to the battlefield survival and combat effectiveness of various weapons and equipment such as fighter planes and missiles. In view of this, a single infrared or laser stealth material can no longer meet the multi-spectrum compatible stealth requirements of various weapons and equipment in modern warfare; in addition, because the relevant stealth material technology involves national strategic interests, it is difficult for domestic scientific and technological personnel to learn from developed countries. technological achievements in this field...
