Abstract

The invention provides an ablation-resistant, wave-absorbing, antiskid and wear-resistant composite coating and a preparation method thereof, and belongs to the field of special functional coatings. The composite coating comprises an anticorrosion bottom layer, an ablation-resistant wave-absorbing sandwich layer, an antiskid and wear-resistant layer and an anti-aging surface layer, and the composite coating is designed through collaborative matching of interlayer thickness to form a multifunctional compatible integrated coating. Compared traditional antiskid coatings, the coating of the invention has the following advantages: the process is simple, the reflectivity of the composite coating is smaller than or equal to -7 dB in a frequency band of 8-18 GHz, the composite coating has a low linear ablation rate and a good anti-aging performance, the static friction coefficient before and after abrasion is larger than or equal to 1.10, the composite coating can pass GJB150 environment testassessment, and the coating design scheme has remarkable technical advancement.

Description

technical field [0001] The invention relates to an ablation-resistant wave-absorbing anti-slip and wear-resistant composite coating and a preparation method thereof, belonging to the field of special functional coatings. Background technique [0002] With the development of a new generation of weapons and equipment, the target detection technology is becoming more and more mature. For naval ships, improving the penetration capability is an effective means to ensure the survival of ships in modern naval warfare. Stealth structure design and the application of radar absorbing materials are increasingly popular. Countries pay attention. Radar stealth technology is a technology that weakens, suppresses, absorbs, and deflects target electromagnetic waves through certain specific materials. As a convenient and economical absorbing material, the absorbing coating was originally developed for the radar absorbing needs of aerospace and aviation vehicles, but with the development of ...
