Embodiment 1

[0031] Weigh 8.5g of PHMS and 7.0g of C 14 Add olefin to a four-necked bottle equipped with a condenser, pass nitrogen gas for 20 minutes to remove the air, and then raise the temperature to 30 °C under the protection of nitrogen atmosphere. C, 3 μl Karstedt catalyst was added. After the reaction started, because the exothermic temperature began to rise, after the temperature was constant, 13.5g of C was added dropwise to the reaction system. 12 Alkene, after the dropwise addition, with 2 C / min heating rate to adjust the reaction temperature to 103 C, reaction 3h, decompression distillation removes unreacted C 14 alkenes and C 12 ene, to obtain a colorless transparent viscous phase change silicone oil (PCS).

[0032] Weigh 2g SiO 2 Disperse in an appropriate amount of xylene or toluene, add 8g of 107 glue (hydroxyl-terminated polydimethylsiloxane), disperse for 5min at 15000rpm with a homodisperser; then add 4 drops of dibutyltin dilaurate catalyst, stir evenly with m...

Embodiment 2

[0036] Weigh 6.0g of PHMS and 5.4g of C 14 Add olefin to a four-necked bottle equipped with a condenser, pass nitrogen gas for 20 minutes to remove the air, and then raise the temperature to 30 °C under the protection of nitrogen atmosphere. C, 2 μl Karstedt catalyst was added. After the reaction started, due to the exothermic temperature began to rise, after the temperature was constant, 9.5g of C was added dropwise to the reaction system. 12 Alkene, after the dropwise addition, with 2 The heating rate of C / min adjusts the reaction temperature to 93 C, reaction 2h, decompression distillation removes unreacted C 14 alkenes and C 12 ene, to obtain a colorless transparent viscous phase change silicone oil (PCS).

[0037] Weigh 1g SiO2 2Disperse in an appropriate amount of xylene, add 6g of 107 glue, and disperse with a homodisperser at 10,000 rpm for 7 minutes; then add 4 drops of dibutyltin dilaurate catalyst, and stir evenly with magnetic force.

[0038] Mix 1.0g of ...

Embodiment 3

[0041] Weigh 10 g of PHMS and 8.2 g of C 14 Add olefin to a four-necked bottle equipped with a condenser, pass nitrogen gas for 20 minutes to remove the air, and then raise the temperature to 30 °C under the protection of nitrogen atmosphere. C, 4 μl Karstedt catalyst was added. After the reaction started, due to the exothermic temperature began to rise, after the temperature was constant, 16.3g of C was added dropwise to the reaction system. 12 Alkene, after the dropwise addition, with 2 The heating rate of C / min adjusts the reaction temperature to 97 C, reaction 4h, decompression distillation removes unreacted C 14 alkenes and C 12 ene, to obtain a colorless transparent viscous phase change silicone oil (PCS).

[0042] Weigh 3g SiO 2 Disperse in an appropriate amount of xylene, add 10g of 107 glue, and disperse with a homogeneous disperser at 170 million rpm for 7 minutes; then add 5 drops of dibutyltin dilaurate catalyst, and stir evenly with magnetic force.

Abstract

The invention relates to a nano composite ice-covering-proof coating containing phase change silicone oil and a preparation method thereof. The ice-covering-proof coating comprises, by mass, 1-50% of phase change silicone oil, 1-50% of nano particles with the particle sizes of 30-80nm, 7-85% of hydrophobic resin, 0-30% of curing agents and 10%-90% of solvent. The preparation method of the ice-covering-proof coating comprises preparing the phase change silicone oil, preparing the hydrophobic resin, and evenly mixing the phase change silicone oil, the nano particles, the hydrophobic resin, the curing agents and the solvent to obtain the coating. The nano composite ice-covering-proof coating and the preparation method have the advantages that preparation raw materials of the coating are easy to obtain, and the preparation process is simple, and the preparation method is easy to operate; and when a coating made by spraying the coating on a metal matrix is at normal temperature and low temperature, the contact angle of water is 155 degrees, the rolling angle is 3 degrees, and the good ice-covering-proof effect is achieved.

Description

Technical field [0001] The present invention involves nano -composite anti -overwing coating and preparation methods containing silicone oil, which is a field of anti -coverage ice coatings and application technology. Background technique [0002] In the atmosphere, overdose in high -voltage tower, transmission lines, communication facilities, and aircraft has caused huge economic losses to countries, and threatened to personal safety. Canada, the United States, and Russia with more than ice and snow weather, especially in the world, especially ice and snow weather,After the ice covering problem was conducted in in -depth and effective research, it can be said that the anti -ice ice problem is one of the major issues that the world has not yet been resolved today. [0003] At present, there are two main types of ice removal technology, one is active ice removal, and the other is passive ice removal.The first mainly uses thermal energy melting, mechanical methods, or spraying a la...
