Technical field
The invention belongs to ship hull coating material and preparing technical field thereof, be specifically related to ship hull coating material of a kind of water-proof climate resisting and preparation method thereof.
Background technology
On the earth, approximately 71% area is all ocean, oceanic resources are very abundant, but because the area of ocean is too wide, therefore need to just can shuttle back and forth in ocean by various ships, while can not get safeguarding if ship navigates by water for a long time in ocean, hull is easy to by seawater, marine atmosphere and marine organism corrsion or adheres to, and affects security and the stability of ship navigation.
At present, there is one to there is waterproof, snow defence, anti-icing, and can, through the material of climate test, be called super hydrophobic material.Prepare super hydrophobic material satisfied two key conditions once of needs conventionally:
(1) material surface has enough roughness, particularly has micro-nano double scales structure.
(2) surfacing is hydrophobic material, has enough low surface energy.
Possess after above two key conditions, by nano inorganic powder and the compound method of polymkeric substance, can effectively utilize the coarse structure of nano-powder material and the hydrophobic property of polymkeric substance, thereby prepare super-hydrophobic matrix material.
And the method for currently used mineral filler and polymer composites realizes the super-hydrophobic following typical problem that at least exists:
(1), in order to obtain high hydrophobic performance, need the needed surface physics roughness of sufficiently high mineral filler guarantee.
(2) membership that adds of the mineral filler of high-content causes the advantageous property of polymkeric substance itself to reduce, and such as hydrophobicity does not reach requirement, therefore mineral filler used generally all needs to carry out hydrophobic modification in advance.In addition, also can reduce the viscosifying power of polymkeric substance and base material.
(3) the mineral filler meeting of high-content causes the viscosity of system excessive, thereby is unfavorable for the construction of the modes such as the spraying, roller coating, dip-coating, brushing of coating.
The existence of above three point problem causes the actual application prospect of high-content mineral filler and polymer super-hydrophobic composite coating greatly to decline, and the use content that reduces mineral filler under the super-hydrophobic function prerequisite of guarantee does not just likely reduce the excellent properties of polymer materials itself as far as possible.
Therefore the ship hull coating material of, developing a kind of water-proof climate resisting excellent performance is the new problem that those skilled in the art require study.
