Description
Technical field
The present invention relates to a kind of mirror back metal plating protective cover modified dry oil alkyd resin and curtain showering material thereof.
Background technology
Mirror has two kinds of production methods: a kind of is to adopt vacuum aluminum-coated method to deposit layer of aluminum as the reflecting layer at glass surface.Second kind is to plate layer of metal silver as the reflecting layer at glass surface earlier by chemical process, plates layer of copper again with chemical process on silverskin then, to increase the reflecting effect and the provide protection of silverskin.Because the metal level of mirror is corroded by topsoil easily, and environment for use places such as big and corrodibility is strong in high humidity, the temperature difference mostly again, metal level is corroded tarnishes to cause the optical property forfeiture.For making mirror back of the body metal level not be subject to chemical corrosion and physical damnification, also need apply the coating protection coating on the mirror back of the body metallic diaphragm.Mirror-back protective coating such as CN1122127A disclosed " coating of glass "; the resin of mirror back reflection layer mixture mainly comprises Synolac, aminoresin and organosilicon adhesion promoters; though Synolac and aminoresin institute coatings formulated have advantages such as good oven dry, acidproof and alkali resistance and hardness is good; but filming of forming really do not have moderate snappiness, the tack and the water resistance of excellence; so use for some time at mirror; coming off still can appear in back of the body lacquer; especially the cutting part at mirror can turn black, and the optical property of mirror is descended.On the other hand, organosilyl price is more expensive, and use cost is higher.
The also useful TDI modified alkyd resin of protective cover of the mirror back of the body.Though filming of making has the water tolerance dried soon, that hardness is high and good, because TDI toxicity is very big, very easily analyses leakage when feeding intake, and pollutes the environment, and influences HUMAN HEALTH.Secondly, will produce gel, so be difficult to realize scale operation owing to careless slightly in the TDI modified alkyd resin making processes.Moreover the TDI price is more expensive, and use cost is higher.
Mirror-back protective coating such as CN1371409A disclosed " based on the fast-dry, high solid content coating of modified alkyd resin "; it is a kind of composition of acrylic acid modified alkyd resin ambient cure high solid; has good performance; because of the densification inadequately of its coating structure; chemical substance is infiltrated easily, and influences the weather resistance of mirror back reflection layer.
In sum, the resin of mirror back paint used film forming thing all exists the single defective of performance at present, when being particularly useful for curtain pouring technology, be subjected to the influence of factors such as the continuous travel line speed of glass temperature, drying time and glass, keep the thickness of coating wet film even, the adjustable difficulty that just seems more that do not diverge.
Summary of the invention
The purpose of this invention is to provide a kind of mirror back metal plating protective cover modified dry oil alkyd resin and curtain showering material thereof; Synolac after the modification can not cause corrosion to mirror back metal plating; has excellent sticking power; hard fragility, snappiness and the characteristics water-fast, acid-fast alkali-proof of appropriateness; can carry on the back the adhesion property that slick metallic surface produces excellence with mirror with the curtain showering material that this modified resin is made; and the compactness of filming is good; anti-water erosion resistance is strong, and having preferably, curtain drenches workability.
Realize that technical scheme of the present invention is: a kind of mirror back metal plating protective cover modified dry oil alkyd resin, comprise main medium-oil-length drying oil alkyd resin by polyvalent alcohol and polyprotonic acid and dry vegetable oil or dry vegetable oil acid synthetic 55-70% weight, and the properties-correcting agent of the Resins, epoxy of the acrylate monomer of 20-30% weight and 10-15% weight; Described medium-oil-length drying oil alkyd resin contains dry vegetable oil or the dry vegetable oil acid more than 40%, the resin that medium-oil-length drying oil alkyd resin and acrylate monomer copolymerization form, and its viscosity (being coated with-4 glasss) 100-200s, acid number is at 30-40mgKOH/g; This resin generates the modified dry oil alkyd resin with Resins, epoxy reaction again, and resin final viscosity (being coated with-4 glasss) 150-300s, acid number be less than 5mgKOH/g, solid part 〉=50% weight.
Wherein:
Described dry vegetable oil is selected tung oil and oleum lini or one of Chinese catalpa oil or synourin oil or their mixture for use, and contains the dry vegetable oil of 45-54% weight in the medium-oil-length drying oil alkyd resin.
