Description
Technical field
The present invention relates to paint field, more particularly to a kind of hydrophobic lacquer and preparation method thereof.
Background technology
With the development of society, people also increasingly focus on painting while paying close attention to the environmental-protecting performance of building coating
The decoration performance of material, to promote flourishing for emulsion paint, lacquer, texture paint, granite coating and multicolor finish.
However since increasing environmental pollution, acid rain take place frequently, coating surface corrosion is on the rise with pollution.Therefore, how exterior wall is improved
Stain resistant and self-cleaning property become coating practitioner and need the critical problem solved.Current self-cleaning approach has 2 kinds：It is super close
Water coating and super-hydrophobic coat.Super-hydrophilic coating is the principle and super hydrophilic characteristic using optically catalytic TiO 2, in rainwater
Under the premise of abundance so that rainwater can coating surface formed it is membranaceous wash away, to play automatically cleaning characteristic.Super-hydrophobic coat
Surface layer and water contact angle be more than 150 °, slide angle be less than 5 °, due to water droplet coating surface be difficult adherency, be easy on surface
It rolls and slides and take away pollutant, can also reach self-cleaning effect, this self-cleaning function is also referred to as " lotus leaf effect
It answers "
The phenomenon that how further increasing hydrophobic performance, promote the adhesive force of coating, and lacquer is avoided to meet water whiting
It is industry technical problem urgently to be resolved hurrily.
Invention content
In view of this, the present invention provides a kind of hydrophobic lacquers and preparation method thereof.The hydrophobic lacquer tool of the present invention

Wherein, the mesh number of the natural colour sand is preferably 200~260 mesh.
The present invention also provides the preparation methods of above-mentioned hydrophobic lacquer comprising following step：It is added in blender
Polymer emulsion, zinc naphthenate, dibutyl tin laurate, organopolysilazane add auxiliary agent, ethoxy after stirring evenly
Cellulose, natural colour sand and water, it is agitated uniform.
The present invention is in lacquer simultaneously added with machine polysilazane, zinc naphthenate and dibutyl tin laurate, three
Synergistic effect is generated, overcomes and the lower defect of organopolysilazane hardness and strength is only used only, not only improve material
Hydrophobic performance, and the defects of avoid the occurrence of crackle, gap.
The positive effect that the present invention obtains：The hydrophobic lacquer of the present invention has excellent water resistance and washability
Performance, coating surface is fine and close, and the strong adhesive force with base material is used for a long time does not crack at high temperature, do not fall off, corrosion-resistant, hydrophobic
Performance is good, hardness and strength higher, and lacquer can effectively be avoided to meet the phenomenon that water whitens.
