Technical field
The present invention relates to a kind of coating, more particularly to a kind of super hydrophobic coating being made up of primer and coating materials to combine
Thing.
Background technology
Super hydrophobic coating is as a emerging product, because it has excellent water proofing property, soil resistance and self-cleaning, in recent years
Constantly pursued.Super-hydrophobic product is widely used in the neck such as antifouling, steamer of exterior aerial, anticorrosion of steel structure, external wall waterproof
Domain.A kind of super-hydrophobicity, wearability and persistence are developed, and the super hydrophobic coating for having good adhesiveness to different substrate materials has
Make great sense.
Published super hydrophobic coating is mainly formed single with usual resins or resin with low surface energy combination hydrophobic granule
Hydrophobic coating, the wearability and persistence of this kind of hydrophobic coating are poor, and the applicability of different substrate materials is more limited to.
Chinese patent CN101143989 discloses a kind of that organosilan gel precursors and silicone oil and nanoparticle are molecular
Hydrophobic coating, the hydrophobic coating can produce super-hydrophobic interface under specific circumstances, but what it utilized is silane gel precursors, is prepared
Complex process and greater risk be present, the hydrophobic interfaces constructed change with the molecular weight of gel precursors, and hydrophobicity is unstable
Fixed and organic silicon coating is poor to the adhesive force of the base materials such as plastics, glass, and its scope of application has limitation.
One kind disclosed in Chinese patent CN101643622 and Chinese patent CN102453425 using furfuryl alcohol resin as binding agent,
Using single hydrophobic granule or micron powder particle as the super hydrophobic coating of filler, simple production process, certain dredge can be played
Water effect, but its hydrophobicity is poor, it is poor to the applicability of a variety of base materials such as plastics, glass.
Chinese patent CN102417773, Chinese patent CN102660182, Chinese patent CN103666173 and Chinese patent
CN103642378 discloses four kinds using fluoroacrylic resin as low-surface-energy binding agent, and hydrophobic nano-particles form for filler
Hydrophobic coating, under specific occasion, it can play preferable super-hydrophobic effect, but its wearability is poor, by of short duration wind
Erosion or friction will lose ultra-hydrophobicity, poor to the adhesive force of a variety of base materials such as plastics, glass, using being restricted.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, there is provided it is a kind of with super-hydrophobicity, it is good resistance to
Mill property and persistence, and all there is the super hydrophobic coating composition of good adhesiveness to various base materials.
For the above-mentioned purpose, a kind of super hydrophobic coating composition of the present invention is made up of primer and coating materials, primer bag

（2）Uniformly by primer sprays on base material, 10-20 minutes are dried；
（3）Uniformly coating materials are sprayed on primer, super-hydrophobic effect can be tentatively shown after drying several minutes.
Beneficial effects of the present invention are mainly manifested in：
1st, there is excellent super-hydrophobicity, wearability and persistence the invention provides a kind of, and to different substrate materials all
Super hydrophobic coating composition with good adhesiveness.
2nd, the present invention uses binding agent of the chlorinated polypropylene as primer, can be glued with a variety of substrate surfaces
Knot, or even have preferable adhesiveness to the difficult viscous material such as polypropylene plastics, glass.
3rd, for the present invention using chlorinated polypropylene as primer, surface still has certain viscosity after film forming, can
The hydrophobic granule of coating materials is adhered to, increases its wearability and persistence.
4th, primer of the present invention uses micron order PP GRANULES, and coating materials use nanoscale hydrophobic granule, by twice
Coating, micro-/ nano concaveconvex structure is formed on surface, coordinates the resin with low surface energy of coating materials, forms super-hydrophobic interface, static state is hated
