Abstract

The present invention relates to providing a kind of anti-moon dust material and application thereof, the anti-moon dust material comprises a base material and a dust-proof coating; the dust-proof coating is a coating formed on the surface of the base material; the dust-proof The coating is formed by the following method: the base material is dip-coated and dried with a dustproof agent to obtain an intermediate base material; A dustproof coating is formed on the surface of the substrate; the substrate is an aluminum substrate or a stainless steel substrate with a surface roughness lower than 100nm; the dustproof agent is mainly made of the following raw materials by weight percentage: perfluorosilane 1% to 5%; silane coupling agent 1% to 2%; the balance is absolute ethanol. The anti-moon dust material of the present invention forms a layer of fluorine-containing modified coating on the surface of the substrate, and the fluorine-containing coating reduces the surface energy of the substrate, reduces the van der Waals force between the moon dust and the surface of the substrate, and can effectively prevent the moon dust from Dust is enriched on the surface of the substrate, which can ensure the normal use of the components of the lunar exploration device.

Description

technical field [0001] The invention relates to the field of materials, in particular to a lunar dust-proof material and its application. Background technique [0002] The moon is covered with a thick layer of lunar dust, which is a regolith formed by meteors impacting the lunar surface, and contains a large number of micron and submicron fine particles. These tiny moon dust particles have high specific surface area and insulation, and under the action of the moon's high temperature, strong radiation environment, and various contacts and frictions, they are easily charged and show strong adhesion. If this lunar dust adheres or accumulates on the lunar probe equipment, it may damage the mechanical parts, block the sensor or reduce the accuracy of the optical instrument, and greatly affect the optical properties of the device, such as absorption rate and emissivity, and then lead to temperature rise. High heat dissipation is difficult. Secondly, the lunar dust is angular and...
