Abstract
The present invention relates to a kind of vacuum plating Special varnish, comprise following component: the solvent of the acrylic resin of 20-28wt%, the aminoresin of 20-27wt%, the epoxy resin of 12-18wt%, the auxiliary agent of 2.5-3.5wt% and 20-35wt%.The excellent performances such as vacuum plating Special varnish weathering resistance of the present invention, corrosion-resistant and shock resistance, there is into thickness, hardness high and wear resistance advantages of higher in addition, be applicable to outdoor use appearance of film and over-all properties and require higher parts, such as, for the application on the surface such as automobile and motorcycle.
Description
Technical field
The invention belongs to the technical field of coating, more particularly, the present invention relates to the vacuum plating Special varnish of the excellent performances such as a kind of weathering resistance, corrosion-resistant and shock resistance.
Background technology
Body of a motor car, in order to antirust and attractive in appearance, needs at its top layer spraying multilayer organic coating.And along with the reach of science, also more and more higher to the performance requriements of these coating, require that it has good weathering resistance, oil-proofness and resistance to acids and bases and physical strength.
At present, varnish mainly comprise by two human subject resins respectively with the amino resin crosslinked varnish solidify to form.Wherein a class is formed by the mode of vibrin and amino resin crosslinked solidification; Another kind of is formed by the mode of acrylic resin and amino resin crosslinked solidification.The coating surface glossiness of the varnish prepared by the mode of vibrin and amino resin crosslinked solidification for the first kind is higher, but the sticking power between paint film and the metal primer of lower floor is poor; For the varnish that Equations of The Second Kind is prepared by the mode of acrylic resin and amino resin crosslinked solidification, although the sticking power between paint film and the metal primer of lower floor is better, coating surface glossiness is comparatively general.And the varnish prepared by this two resinoid and amino resin crosslinked solidification under some specific environment as easily there is degradation with aging under oxygen, acid rain etc. act on, namely the weatherability of paint film and erosion resistance all poor.
Summary of the invention
In order to solve above-mentioned technical problem of the prior art, the object of the present invention is to provide the vacuum plating Special varnish of the excellent performances such as a kind of weathering resistance, corrosion-resistant and shock resistance.
In order to realize foregoing invention object, vacuum plating Special varnish of the present invention, comprises following component: the solvent of the acrylic resin of 20-28wt%, the aminoresin of 20-27wt%, the epoxy resin of 12-18wt%, the auxiliary agent of 2.5-3.5wt% and 20-35wt%.
Wherein, described acrylic resin is selected from one or more in (methyl) methyl acrylate, (methyl) ethyl acrylate, (methyl) propyl acrylate, (methyl) butyl acrylate cores, (methyl) Ethyl acrylate, (methyl) vinylformic acid (-2-ethylhexyl) ester, (methyl) n-octyl, (methyl) lauryl acrylate or (methyl) octadecyl acrylate.
Wherein, described aminoresin is methyl etherified melamine resin or methyl-etherified hexamethylol melamine resin.
Wherein, described auxiliary agent can come selectively to use as required, and such as described auxiliary agent is selected from least one in dispersion agent, defoamer or flow agent.
Wherein, described solvent is the mixture of methylcarbonate, diethyl carbonate, Methyl ethyl carbonate and Virahol.The present invention uses described mixed carbonate ester series solvent to substitute traditional organic solvent, not only environmental protection in described vacuum plating Special varnish, and the surface quality that can significantly improve coating, improves the solvent resistance of described metallic paint.
Compared with prior art, the present invention has following beneficial effect:
The excellent performances such as vacuum plating Special varnish weathering resistance of the present invention, corrosion-resistant and shock resistance, there is into thickness, hardness high and wear resistance advantages of higher in addition, be applicable to outdoor use appearance of film and over-all properties and require higher parts, such as, for the application on the surface such as automobile and motorcycle.
