Description
Technical field
The invention belongs to the preparation of coating and applied technical field, and in particular to a kind of permanent seal cooling super-hydrophobic coat and its system
Preparation Method.
Background technology
Super hydrophobic surface refers to is more than 150 ° with the contact angle of water droplet, and roll angle is less than 10 ° of surface.Sent out from " lotus leaf effect "
Since existing, super hydrophobic surface has extensive use in fields such as automatically cleaning, anticorrosive mildewproof, anti-icing frost prevention and water-oil separatings.Tradition
Method for preparing super-hydrophobic surface, mainly build micro-nano coarse structure in substrate surface by bionical means, and with low table
Face energy material modification, or directly in low-surface-energy material surface construction coarse structure.These methods to base material requirement compared with
Height, process equipment is complex, accomplishes scale production more difficult.So if simplifying, prepare containing micro-nano particle
Super-hydrophobic coat, it is coated on required substrate surface, then base material is required without excessive in itself, easily realized, and be easy to advise
Modelling produces.
With the further investigation to super-hydrophobic coat, it is found that super-hydrophobicity and wearability are conflicting to a certain extent.
The general resin content of coating with good ultra-hydrophobicity is few, and granule content is more, and under external force, particle easily comes off,
Coating abrasion performance is poor.And if increase resin content, particle are then easily covered by resin, coating roughness declines, and ultra-hydrophobicity becomes
Difference.Therefore, how to solve this contradiction, ensure that improving its wearability while coating ultra-hydrophobicity turns into study hotspot.Closely
Nian Lai, the main method of proposition include adhesion between enhancing coating and substrate, prevent particle in mechanicals efforts lower part or complete
Come off entirely so as to reduce surface roughness, raising of this method to wearability is limited, to reach good result, it usually needs
Add last layer priming paint in addition between coating and substrate, this makes technique become complicated again, and materials are expensive.
Based on this, the present invention proposes a kind of new method for preparing permanent seal cooling super-hydrophobic coat, efficiently solves super thin
Water-based and this conflicting technical barrier of wearability.This method is not required to be further provided with priming paint, and apparatus and process is simple, easy to operate,
It is adapted to extensive prepare to produce, the coating abrasion performance of gained is good, and superhydrophobic characteristic is not easy to be destroyed, suitable for various common bases
Bottom material, it can be widely applied to super-hydrophobic field.
The content of the invention
The technical problem of solution：To solve this not wear-resisting technical barrier of super hydrophobic surface, the present invention provides a kind of durable
Type super-hydrophobic coat and preparation method thereof.Present device technique is simple, easy to operate, is adapted to extensive prepare to produce.
Technical scheme：A kind of preparation method of permanent seal cooling super-hydrophobic coat, preparation process are：It is prepared by hybridization coating：100-

Beneficial effect：（1）Hydrophobicity micro-nano particle is scattered in volatile organic solvent first, is advantageous to improve then
The uniformity that particle disperses in resin, effectively prevent the generation of particle agglomeration.（2）Hydrophobicity micro-nano particle and hydrophobicity tree
The mass ratio of fat is controlled at (2-3):In the range of 10, enough numbers of particles are on the one hand ensure that, particle will not be completely by resin
Covering, on the other hand, resin content is more, good to particles stick, and adhesion is good between substrate.（3）Hybridization coating is carried out
Semi-solid preparation processing, promotes particle and resin bonding, but because not being fully cured, particle is Nian Jie with interlaminar resin close not too much, favorably
Particle is exposed in follow-up immersion process, so as to reach preferable coarse structure.（4）Using soak this simple process, one
Aspect promotes resin to dissolve, and skin granulate is constantly exposed, and roughness improves, and super-hydrophobicity is more preferable；On the other hand promote solid
Change, improve particle degree Nian Jie with interlaminar resin, go skim-coat to be bonded unstable particle, strengthen coating transparent, improve comprehensively
Coating abrasion performance.（5）Preparation method of the present invention does not have particular/special requirement to base material and its shape, suitable for metal, glass
