Abstract

The invention discloses an environmentally-friendly organic inorganic hybridized paint and preparation method and application thereof. The preparation method includes that acrylosilane microemulsion is taken as binder, 2-35 parts of acrylosilane microemulsion containing hydroxyl is dissolved into 10-80 parts of alcohols solvent, 1-15 parts of tetraethoxysilane, 2-30 parts of organosiloxane and 0.5-10 parts of basic catalyst are added, hydrolysis and polycondensation are carried out in organic polymer emulsion to form hydrophobic inorganic network, so as to obtain organic inorganic hybridized acrylosilane paint. The paint is coated on the surface of water poly(methyl) acrylic ester primer and is dried, thus obtaining the organic inorganic hybridized super-hydrophobic coating with favourablemechanic performances. The adhesive force of the super-hydrophobic coating can achieve 1-2 level, water static contact angle is more than 150 degrees, and rolling angle is less than 10 degrees. The invention is simple in technology, available in raw materials and low in cost and overcomes the defects of the existing preparation technology and the disadvantage of poor mechanical performances of the super-hydrophobic coating.

Description

technical field [0001] The invention relates to an organic-inorganic hybrid coating, in particular to an environment-friendly organic-inorganic hybrid coating and a preparation method thereof. The coating can be used to prepare an organic-inorganic hybrid super-hydrophobic coating. Background technique [0002] The organic-inorganic hybrid material is a homogeneously dispersed multi-phase material, which combines the performance advantages of organic polymers or inorganic polymers.
