▎ 摘  要

NOVELTY - Micro-capsule comprises 8-10 pts. wt. polyacrylonitrile and polyurethane, 27 pts. wt. dimethylformamide, 3-6 pts. wt. paraffin, 0.5-2.5 pts. wt. electromagnetic wave absorbent, 0.1 pts. wt. hydroxycellulose and 10 pts. wt. deionized water. USE - The microcapsule is useful for preparing and applying infrared and radar stealth materials to military targets (claimed). ADVANTAGE - The micro-capsule combines phase change materials and electromagnetic wave absorbing materials; has both infrared and radar stealth functions; is convenient to use and can be directly sprayed on military targets to achieve good stealth effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing microcapsules comprising (a) dissolving polyacrylonitrile, polyurethane in 15 pts. wt. dimethylformamide solvent to obtain solution one, (b) adding paraffin, electromagnetic wave absorbent and hydroxycellulose to 10 pts. wt. dimethylformamide solvent, fully stirring, emulsifying to obtain solution two, (c) adding the solution two to solution one in a ratio of 1:1, stirring to obtain the mixed solution three, (d) dissolving 2 pts. wt. dimethylformamide in 10 deionized water to prepare solution four and (e) spraying solution three into solution four through a high-pressure and high-temperature sprayer to obtain the microcapsules.
