Multifunctional radar wave reflection soft protective material and preparation method thereof

Abstract

The invention relates to the field of radar wave reflection, in particular to a multifunctional radar wave reflection soft protective material and a preparation method thereof. The soft protective material comprises a PVC coating layer I, a bonding layer I, a piece of carbon fiber base cloth, a bonding layer II and a PVC coating layer II. The first layer and the fifth layer on the upper and lowersurfaces are respectively the PVC coating layer I and the PVC coating layer II, the third layer in the middle is the carbon fiber base cloth, and the second layer and the fourth layer are respectivelythe bonding layer I and the bonding layer II coating the upper and lower surfaces of the carbon fiber base cloth. The raw materials of the PVC coating layers include polyvinyl chloride resin, plasticizer, flame retardant, filler, stabilizer and anti-ultraviolet agent. The soft protective material is prepared by the steps of slurry preparing and grinding, base cloth drying, soaking, rolling, scrape coating and sizing, plasticizing and drying, and the like. The soft protective material of the invention has good radar wave reflection performance, and has the advantages of low weight, high strength, water proofing, flame retardancy, ultraviolet protection, and the like.

Description

technical field

[0001] The invention relates to the field of radar wave reflection, and in particular provides a soft protective material for multifunctional radar wave reflection for ground mobile facilities and a preparation method thereof. Background technique

[0002] With the rapid development of the electronics industry, electronics, electrical appliances and radio communications are widely used, and the accompanying electromagnetic radiation pollution has become the fourth largest pollution after air pollution, water pollution and noise pollution. Electromagnetic waves not only cause serious harm to human health, but also interfere with various electronic equipment, hinder the normal operation of electronic equipment, and threaten the information security of communication equipment. Electromagnetic interference, leaking and other issues have become important concerns in the fields of electronics, information, and communications. question. At present, the main method ...

Examples

Embodiment Construction

[0027] Such as figure 1 As shown, the soft protective material for multifunctional radar wave reflection of the present invention adopts a flexible composite material of carbon fiber base cloth, and its main structure includes: PVC coating layer I1, adhesive layer I2, carbon fiber base cloth 3, adhesive layer II4, PVC coating layer Ⅱ5 and other five layers, of which: the first layer and the fifth layer on the upper and lower surfaces are PVC coating layer Ⅰ1 and PVC coating layer Ⅱ5 respectively, which play the role of anti-rain and anti-aging; the third layer in the middle is The carbon fiber base cloth 3 has high strength and flexibility; the second layer and the fourth layer are the adhesive layer I2 and the adhesive layer II4 coated on the upper and lower surfaces of the carbon fiber base cloth 3 to improve the bonding of the PVC coating layer Strength, the adhesive layer is made of polymer adhesive and PVC resin material mixed in a weight ratio of 1:1.
