Abstract

The invention relates to a snowfield camouflage net white microporous coating which comprises a flame-retardant layer surface white coating, a flame-retardant coating, a low-emissivity base material and a low-emissivity surface white microporous camouflage coating which are sequentially stacked from bottom to top. The snowfield camouflage net white microporous coating is prepared by coating a white foaming coating on a low-emissivity base material, and the back surface is coated with the flame-retardant coating and the white camouflage coating on the surface of the flame-retardant layer to obtain the snowfield camouflage net white microporous coating. The probability that equipment is found by ultraviolet, visible light and infrared detection equipment in a snowfield background can be effectively reduced by the coating and the survival opportunity of the equipment in the snowfield background is improved. In addition, the invention also relates to a preparation method of the snowfield camouflage net white microporous coating.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a white microporous coating of a snow camouflage net and a preparation method thereof. Background technique [0002] With the development of reconnaissance technology, and snow is an important background of modern warfare, the anti-reconnaissance camouflage requirements for equipment in the snow background are becoming more and more stringent. Not only in the visible light band, it is necessary to integrate the equipment camouflage with the snow background, but also in ultraviolet light. The equipment camouflage in the band and thermal infrared band can be well integrated with the snow background. The white camouflage of traditional camouflage equipment in the visible light band mostly uses titanium white as the pigment of the camouflage coating, but the ultraviolet reflectance of titanium white in the ultraviolet band (300nm-380nm) is even lower than 10%...
