Embodiment 1
[0014] Add 70% of the formula amount of the solvent (prepared by xylene, propylene glycol methyl ether acetate, methyl isobutyl ketone and 100# solvent oil in a ratio of 1:1:1:1) to the condenser tube and oil-water separator In the reaction kettle, heat up to reflux temperature, then mix 100% monomers [styrene (5%), isobornyl methacrylate (20%), butyl methacrylate (15%), methacrylic acid Hydroxyethyl ester (15%), butyl acrylate (20%), methacrylic acid (10%) and fluorine-containing monomer (15%) were injected into the dropping tank, and then dissolved and diluted with 10% solvent to dilute 80% of the calculated amount The initiator was injected into another dropping tank, and the liquids in the two dropping tanks were uniformly dripped into the reaction system in 4 hours. After the dropwise addition, keep the temperature at reflux for 1.5 hours, and then add the remaining solvent and initiator dropwise into the reaction kettle at a uniform speed within 1.5 hours. According to ...
Embodiment 2-4
[0018] Referring to the preparation steps of Example 1, the difference is: the ratio of styrene: fluorine monomer (respectively using hexafluorobutyl acrylate and hexafluorobutyl methacrylate) in the raw material of the monomer ratio is 5%: 15 %; 10%: 10%; 15%: 5%.

Abstract
the invention discloses a fluorine modified acrylic resin and preparing method for helicopter covering paint, which comprises the following steps: blending composite monomer methacrylic acid borneol ester, n-butyl methacrylate, hydroxyethyl methacrylate, butyl acrylate, methacrylic acid and fluorine monomer in the composite solvent with xylene, propylene glycol methyl ether acetic ester, methyl isobutyl ketone and 100# solvent oil; dripping carbonic glycide ester to polymerize acted by trigger pentaphen peroxide to obtain the product.
Description
technical field [0001] The invention relates to the manufacture of resins for helicopter skin coatings, in particular to the field of manufacture of fluorine-modified acrylic resins. Background technique [0002] The environment of helicopter flight is complex and changeable, and the climate, spring, summer, autumn and winter, and the atmosphere of various places will change. Therefore, the coatings used are required to be resistant to ultraviolet rays, rain erosion, aging, and high and low temperature. It is also required to conduct electricity, heat insulation, anti-icing, anti-fog, heat resistance, oil resistance, absorption, radiation or transmission of certain electromagnetic waves, etc. The coatings used by helicopters should also be able to resist the erosion of various liquids used by the aircraft itself, such as anti-lubricating oil, hydraulic oil, kerosene, etc. The performance of the resin directly affects the performance of the coating, so high-performance resin...
