Abstract
The invention discloses a kind of polyurethane resin frosted coating and preparation method thereof, does is its constitutive material: a kind of polyurethane resin frosted coating, is characterized in that the weight portion of its constitutive material is: polyurethane resin 50-65, ethylene polyamine class curing agent 1.4-1.8, glass dust 15-20, polyurethane levelling thickener pu-8080? 0.15-0.25, rosin acid polyoxyethylene ester 1.0-2.0, polyisobutene 3.8-4.5, magnesium carbonate 10-15, polyvinyl acetate emulsion 5.0-7.0, vinyl three ('beta '-methoxy ethyoxyl) silane 2.3-2.5 and diatomite 30-35. As long as the present invention is direct on glass that the coating direct spraying of producing by the present invention is cleaned up in process, toast 180 DEG C and get final product to obtain imitative frosted finish effect, film performance excellence, the persistence of film, water-fast, moisture-proof, good corrosion resistance, adhesion property is splendid, and after the glass of film falls on the ground and breaks into pieces, glass dregs can not scatter everywhere, but be broken into one, improve the safety in utilization of glass.
Description
Technical field
The present invention relates to art of powder coatings, relate in particular to a kind of polyurethane resin frosted coating and preparation method thereof.
Background technology
Light fixture, for reaching the effect that light is soft, conventionally all selects ground glass, but produces ground glass with machining process, and as blasting craft, not only labour intensity is large, and effect is not ideal enough.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of polyurethane resin frosted coating and preparation method thereof is provided.
The present invention adopts following technical scheme to achieve these goals:
A kind of polyurethane resin frosted coating, is characterized in that the weight portion of its constitutive material is: polyurethane resin 50-65, ethylene polyamine class curing agent 1.4-1.8, glass dust 15-20, polyurethane levelling thickener pu-80800.15-0.25, rosin acid polyoxyethylene ester 1.0-2.0, polyisobutene 3.8-4.5, magnesium carbonate 10-15, polyvinyl acetate emulsion 5.0-7.0, vinyl three ('beta '-methoxy ethyoxyl) silane 2.3-2.5 and diatomite 30-35.
