Abstract
The invention relates to a mirror back protective coating for a copper-free silver mirror. The protective coating comprises base coat and finishing coat, wherein both the base coat and the finishing coat comprise modified alkyd, acrylate resin, novolac epoxy resin and crosslinked resin. The novolac epoxy resin and the crosslinked resin can form a rigid netted dense structure after undergoing a high-temperature curing reaction, so that the corrosion resistance of the coat is greatly improved, long-term effective protection of a silver layer is realized, and the coat is endowed with appropriate rigidity and scratch resistance. The coating of the invention contains a great amount of radicals such as epoxy groups, ether bonds, hydroxide radicals and the like, thereby greatly increasing the adhesive force of the coat. The coating of the invention does not adopt anti-corrosion lead-containing compounds, thereby avoiding environment pollution. The coating of the invention can adopt a large-scale curtain-coating molding process, can realize quick drying, can be completely solidified after being roasted at the temperature of between 120 and 150 DEG C for 5 to 8 minutes, has excellent physical and chemical properties and contributes to large-scale industrial production.
Description
Technical field
The present invention relates to a kind of mirror back paint, relate in particular to the protection of a kind of copper-free silver mirror mirror back of the body and use coating, comprise priming paint and finish paint.
Background technology
The manufacture method of mirror is to plate various metals with methods such as wet chemistry plating technic or vacuum evaporations earlier on glass substrate, the commonly silverskin of 80-150nm or aluminium film, to play the reflection ray effect, difference according to the reflecting layer is called silver mirror and aluminium mirror, and wherein silver mirror is because imaging is clear thereby be widely used in this high-grade place.In silver mirror; in order to protect silver layer also need use the method plating layer of metal copper of bronze mirror chemical reaction; for making metal level not be subjected to chemical corrosion and physical damnification; also need primer coating and finish paint to be protected on the metal plating; wherein the bronze mirror chemical reaction can produce environmentally harmful ferrous compound; do not need plated copper layer again and there be copper layer silver mirror, do not produce ferrous compound, belong to environmentally friendly product.
Chinese invention patent ZL200410064986.5 discloses a kind of mirror back metal plating protective cover modified dry oil alkyd resin and curtain showering material thereof.This coating comprises the medium-oil-length drying oil alkyd resin of 55-70% weight, and the properties-correcting agent of the Resins, epoxy of the acrylate monomer of 20-30% weight and 10-15% weight, the resin that medium-oil-length drying oil alkyd resin and acrylate monomer copolymerization form.This curtain showering material by the preparation of modified drying oil alkyd is used to have the protection of copper silver mirror to play a very good protection; but when being used to not have copper layer silver mirror; one side and metal level do not have good adhesive; can make no copper layer silver mirror edge blackout on the other hand, and condition such as high temperature in the edging course of processing in later stage and poach and make protection silver layer deepening or variable color.
Chinese invention patent application 200610147655.7 discloses a kind of preparation method of single-coating-type paint for copper layer free glass silver mirror back, by consisting of metal oxide 7.0-8.0wt%, superfine talcum powder 9.0-11.0wt%, ultra-fine barium sulfate 15.0-37.0wt%, short-oil alkyd 20.0-30.0wt%, tinting pigment 3.0-10.0wt%, anti 0.05-0.15wt%, siccative 0.01-0.08wt%, optical brightener 0-3.5wt% and organic solvent are prepared from.The coating that this method makes has the disposable advantage that singly is coated with construction; but owing to only use a kind of organic constituent of short-oil alkyd; its protective value to silver layer is more single; can't satisfy more performance requriements such as high corrosion resistance and anti-ammoniacal liquor of no copper layer silver mirror; and contain lead compound in the pigment, environment is had potential harm.
Conventional have copper silver mirror back protective cover can't be used for environment-friendly type not have copper layer silver mirror, and these coating can't form better sticking power to silver layer, also can't provide superior corrosion resistance, anti-CASS and performances such as salt-fog test and anti-ammoniacal liquor.
