The paint composed of the resin, proper crosslinked resin, pigment, extender pigment, an assistant and a solvent has the good performance of low solidification temperature, high speed, high hardness of a paint film, good flexibility, strong adhesive force and chemical corrosiveness resistance, etc., and can well adapt to a silver mirror production line generally used in China. The present invention has the advantage of good application performance, and can effectively ensure the good quality of silver mirrors.
Description
Technical field
The present invention relates to a kind of resin and coating thereof, particularly a kind of mirror back metal plating protective cover mirror back lacquer resin and curtain showering material thereof.
Background technology
Mirror mainly contains two kinds of aluminium mirror and silver mirrors.Cheap but the poor performance of aluminium mirror, silver mirror class high quality is good, but production cost is higher.Mainly be to use silver mirror in developed country at present, along with expanding economy, China silver mirror market is also in continuous expansion.
The silver mirror production technique is: by chemical process earlier at glass surface plating layer of metal silver as the reflecting layer, and then on silverskin, plate layer of copper, with the reflecting effect that increases silverskin and protect silverskin.Applying protective cover again on the copper film surface is mirror back lacquer.
Superior in quality mirror back lacquer can be protected silver, the copper metal layer at the mirror back side, allows mirror for a long time as new, and the hot and humid and severe corrosive environment that can bear bathroom and toilet.Mirror back lacquer such as CN1122127A disclosed " coating of glass ", adopt Synolac, aminoresin and organosilicon adhesion promoters, though the coating that makes is having raising aspect drying rate and the hardness, snappiness, sticking power and weather resistance aspect are still not enough.So after mirror used for some time, coating still came off, 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.
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, but because of the densification inadequately of its coating structure, chemical substance is infiltrated easily, and influences the weather resistance of mirror back reflection layer.
CN1621430A disclosed " mirror back metal plating protective cover modified dry oil alkyd resin and curtain showering material thereof "; just can reach the exsiccant requirement in 5 minutes at 180 ℃; and a large amount of import silver mirror production line bake out temperatures that use of China and time be 130 ℃-150 ℃ 3 minutes; therefore, this coating still can not satisfy downstream client's demand.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, a kind of mirror back metal plating protective cover mirror back lacquer resin and curtain showering material thereof are provided.
The technical solution adopted in the present invention is for achieving the above object: a kind of mirror back lacquer resin, it is characterized in that comprising in this resin solids the medium oil alkyd of 50-70% weight, the Acrylic Acid Monomer of 20-40% weight and acrylic polymer, and the resol of 5-10% weight; Described medium oil alkyd is selected one of tung oil, oleum lini, zinc oil, synourin oil or its mixture for use, and medium oil alkyd always contains the vegetables oil of 45-60% weight; Described medium oil alkyd and Acrylic Acid Monomer and prepolymer mix obtaining sold resin again with resol; It is coated with-4 glasss of viscosity is 100-300s; Acid number is below 5mg KOH/g.
The Acrylic Acid Monomer of described 20-40% weight and acrylic polymer comprise the Acrylic Acid Monomer of 10-20% weight and the acrylic polymer of 10-30% weight.
Described Acrylic Acid Monomer comprises the methyl acrylate of 2-3% weight, the isobutyl acrylate of 3-5% weight, the glycidyl methacrylate of 3-10% weight, the N hydroxymethyl acrylamide of 1-3% weight, the acrylamide of 1-3% weight.
Described acrylic polymer is by the methyl methacrylate of 5-14% weight, and the Butyl Acrylate Monomer of the vinyl cyanide of 4-15% weight and 1-3% weight prepares.
A kind of curtain showering material that contains above-mentioned mirror back lacquer resin comprises priming paint and finish paint, it is characterized in that described priming paint and finish paint are by mirror back lacquer resin, cross-linked resin, tinting pigment, pigment extender, auxiliary agent and solvent composition; Primer composition weight is that absolutely proportioning is as follows by various composition sums: the mirror back lacquer resin of solids constituent 50%: 30-40, the cross-linked resin of solids constituent 60%: 3-4, tinting pigment: 15-30, pigment extender: 15-35, auxiliary agent: 1-2, solvent: 10-25; The finish paint composition weight is that absolutely proportioning is as follows by various composition sums: the mirror back lacquer resin of solids constituent 50%: 40-50, the cross-linked resin of solids constituent 60%: 4-5, tinting pigment: 5-15, pigment extender: 20-40, auxiliary agent: 2-4, solvent: 10-25.
Mirror back lacquer resin provided by the invention mainly comprises three kinds of resinous principles: medium oil alkyd, acrylic resin and resol.Wherein crucial especially is acrylic resin, and different with the various mirror back lacquer resins of having reported is, the present invention uses Acrylic Acid Monomer and performed polymer simultaneously, and the present invention does not use Resins, epoxy yet.
The present invention generates medium oil alkyd by glycerine, tetramethylolmethane or TriMethylolPropane(TMP) and vegetables oil through alcoholysis, esterification, introduces suitable conjugated double bond by the consumption of regulating vegetables oil.The quick-dry type Synolac is synthesized in a part of conjugated double bond in the vegetables oil and Acrylic Acid Monomer copolymerization.The adding of acrylate prepolymer can be accelerated rate of drying, and improves paint film property, thereby can reach good dryness, hardness and resistance to chemical attack ability.The adding of resol can improve hardness of paint film.The present invention does not use Resins, epoxy yet, because of it might cause the paint film yellowing.
The present invention is by the control to medium-oil-length oil alkyd resin, Acrylic Acid Monomer and prepolymer and resol consumption, through making polyester chain, conjugated alkene chain and hydroxyl, ester bond and the carboxyl that contains appropriateness in the molecular chain of mirror back lacquer resin of the present invention at resin after the multistep modification.Make that this mirror back lacquer resin has that rate of drying is fast, hardness is high, snappiness is good, excellent properties such as good corrosion resistance, sticking power are good.Mirror back lacquer resin of the present invention can make the amino crosslinked netted high polymer that produces complexity in hydroxyl, carboxyl and the cross-linked resin in the resin in cross-linked resin heated baking process, be suitable for very much an act showering material.
