Problems solved by technology

[0004] Researches on anti-icing and wave-absorbing coatings at home and abroad are relatively independent, and there are few reports on intelligent coatings that can take into account both anti-icing and wave-absorbing functions in the world, but the technical demand for the coupling of anti-ice and wave-absorbing dual functions is increasing day by day

Embodiment 1

[0091] The present embodiment provides a light-cured fluorinated epoxy resin, and its preparation method is as follows:

[0092] Take perfluorooctyl ethyl acrylate (6.22g, 12mmol), glycidyl acrylate (0.52g, 4mmol) and methyl acrylate (0.34g, 4mmol) were added to 10mL of dimethyl sulfoxide (DMSO), Complete dissolution under magnetic stirring (300 rpm) followed by dropwise addition of azobisisobutylcyanide AIBN (32.8 mg, 0.2 mmol). After removing the oxygen in the system, a nitrogen protective atmosphere was introduced and sealed, and the free radical copolymerization reaction of the three monomers was initiated at 60°C for 12 hours. After the reaction is stopped, the obtained solution is settled in diethyl ether, filtered and dried to obtain a light-cured fluorinated epoxy resin terpolymer, which is sealed and stored.

[0093] The number intrinsic viscosity of the photocurable fluorinated epoxy resin prepared in this example is about 34dL / g, the melt index is about 2.6g / 10min,...

Description

technical field [0001] The invention relates to a coating material, in particular to a coating material system with anti-icing and wave absorbing functions. Background technique [0002] The successive advent of advanced electromagnetic detection technology has put forward higher requirements for the ability of equipment to counter electromagnetic wave detection. Coating absorbing materials can effectively reduce the electromagnetic wave reflection characteristics of one's own equipment to shorten the actual detection distance of the opponent's radar. Compared with the method of electromagnetic stealth optimization of appearance, it has the advantages of less design difficulty, low manufacturing cost, and simple application conditions. However, the absorbing coating is often used in complex and harsh climate environments such as high humidity and high cold, and is severely tested by severe cold and freezing, which will cause the absorbing coating to have problems such as sur...
