Description
Technical field
Applied the present invention relates to technical field of coatings, more particularly to a kind of carbon black loadings molybdenum disulfide antifriction type super-amphiphobic hydridization
Material.
Background technology
Wetability is a key property of the surface of solids, it is conventionally believed that the microstructure and chemical group of the surface of solids
The wetability that it is shown in pairs plays a key effect.The wetability of the surface of solids rises in daily life and industrial and agricultural production
Critically important effect, such as washing, printing and dyeing, the scattered of coating, the use of lubricating oil and the infiltration of skin care item.Current people
Do not got wet this, and the phenomenon that water droplet oneself can be tumbled is referred to as super-hydrophobic phenomenon, and the surface with this property is claimed
For super hydrophobic surface, researcher is more for the research of super hydrophobic coating, but the type coating be often easily stained with oil stain and compared with
Hardly possible is removed, therefore greatly limit the application and popularization of the type coating.Double open coats are due to alienation while it is for water and oil
Effect, simple super-hydrophobic coat of holding one's breath is easier applied among daily life and industrial production.But it is existing at present
Super-hydrophobic oleophobic coating preparation method has the following disadvantages：Need special installation（Plasma, laser ablation）, be unfavorable for large area
Construction, has particular/special requirement to ground, is only applicable to particular surface, and universal complex forming technology, with high costs, therefore seriously
Limit the extensive use of such material.
Xu Runbin exists《The preparation and research of super-hydrophobic/oleophobic coating》In one text nanometer is prepared for by conventional grinding methods
Alundum (Al2O3) particle, nano-silicon dioxide particle is prepared for using sol-gel process, utilizes fluorine-containing silane coupler difference
Surface grafting processing is carried out to both, the nano-particle and micro particles of surface fluorine modification has been obtained as color stuffing, next is adopted
A kind of fluorine-containing Hydroxylated acrylic resin is prepared as the main resin of adhesive, selection perfluoroalkyl with polytype acrylic monomers
Ethanol and hexamethylene diisocyanate trimer prepare a kind of fluorine-containing isocyanate curing agent, and as a result paint is matched somebody with somebody in surface by mixing
The acroleic acid polyurethane varnish paint film property of preparation is good, adhesion 1 grade, pliability 1mm, impact 50cm, hardness 2H, for water
Static contact angle reach as high as 104 °, finally obtained nanometer, micro particles are scattered in fluorine-containing Hydroxylated acrylic resin,
The ratio of pigment and nano/micrometre particle is adjusted, and is equipped with dispersant, anti-settling auxiliary agent and curing agent and is made a variety of super thin
Water-oleophobic coating, testing result show coating there is preferable adhesive force, pliability and paint film intensity, now film for water,
The static contact angle of rapeseed oil and aircraft fluid is respectively 154 °, 100 ° and 94 °, illustrates that the coating is shown to water and oil
Good alienation effect, although the preparation method proposed in this article has certain effect in terms of hydrophobic and oleophobic, still
It is not reaching to and 150 °, and intensity, wearability, durability, stability and the mechanical performance one of coating is more than to the contact angle of oil
As, actual use demand is can not meet, the commercial Application of super-amphiphobic coating is limited.
