Environmentally-friendly organic inorganic hybridized paint and preparation method and application thereof

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 favourable mechanic 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. This kind of highly fine mixing makes the hybrid materials exhibit the optical transparency, adjustable refractive index, mechanical properties, high temperature resistance, wear resistance, flexibility, functionality, etc. that single organic polymer materials or inorganic materials do not have. superior performance.

AI Technical Summary

Problems solved by technology

The preparation method is simple, has good repeatability, and has no environmental pollution, but this method requires high-temperature baking, and the adhesion and mechanical strength of the coating film are difficult to meet the requirements, and the expensive perfluorosiloxane is used, which makes the production cost higher

Using hydrophobic polymers as precursors, porous aluminum plates with different pore sizes and density distributions as templates, and extruding polymer melts or solutions to prepare polymeric nanofiber bundles with superhydrophobic surfaces. Shaped porous aluminum plate is not easy to prepare, and it is impossible to process special-shaped surface or large-area surface

Using the chemical wet selection method to control the porous structure of the block polymer surface by selecting a suitable solvent and temperature to prepare a superhydrophobic coating film, there are also limitations such as the need to use an organic solvent system and the poor adhesion of the coating on the surface of the substrate, etc.
