Abstract
The present invention discloses a single-coated epoxy paint copper-free silver mirror and a preparation method thereof. The single-coated epoxy paint copper-free silver mirror includes glass substrate and a silver layer. The silver layer is coated on the surface of the glass substrate, and the silver layer is provided with an epoxy lead-free protective paint layer with a thickness of 35-40 [mu]m. The production process is as follows: (1) polishing the surface of the glass substrate by using a polishing powder, spraying a sensitizing agent solution after rinsing by deionized water, and rinsing with deionized water after standing; (2) spraying an activator solution; (3) plating the silver layer and a passivator layer on the glass substrate surface; (4) rinsing the glass substrate treated by the step (3) with deionized water and then drying; (5) preheating to 50-55 DEG C processed by the step (4), coating a protective paint layer of 35-40 [mu]m by using curtain-type shower coating; and (6) drying the protective paint layer at 135-150 DEG C, wherein the drying time is more than 3 minutes, and then cooling to room temperature. The copper-free silver mirror provided by the present invention is clear and not easy to fall off, the production process is simple and feasible, and the copper-free silver mirror has high chemical resistance and corrosion resistance.
Description
Technical field
The present invention relates to a kind of silver mirror and production technique thereof, particularly a kind of copper-free silver mirror with single-coated epoxy paint and production technique thereof.
Background technology
The production method of simple glass silver mirror is to plate layer of metal silver as the reflecting layer on the glass baseplate surface with the method for silver mirror chemical reaction first at present; and then with the method for bronze mirror chemical reaction at silver layer plating layer of metal copper, to increase reflecting effect and the provide protection of silver layer.For the metal level that makes glass silver is not subject to chemical corrosion and physical damnification, usually on the glass silver metal level, also want primer coating and finish paint to protect metal level.But in the bronze mirror chemical reaction, can produce a lot of heavy metals, very large to environmental influence, in addition traditional when having bronze mirror to produce after the silver layer outside plates layer of copper more often work in-process a lot of problems appear, the free-cutting that for example adds the emery wheel in man-hour causes the glass end-heating, so that silver causes microdeformation with copper because the coefficient of expansion is different, the outside air moisture will corrode silver layer, and the silver layer reflectivity is reduced, and affects the work-ing life of silver mirror.For the problems referred to above, the preparation method of copper-free silver mirror has been proposed at present a lot of prior aries, but still have some defectives: for example publication number is the preparation method of copper-free silver mirror described in the patent of CN101570403A, protective paint adopts showering prime coat and showering top coat layer two procedures to carry out, so that complex technical process, increased production unit and produced occupation of land, human and material resources increases simultaneously, so that this kind silver mirror production cost increases greatly; Protective paint adopts alkyd varnish to make priming paint and finish paint mostly at present, but the method that there is no satisfies the higher resistance to chemical attack of copper-free silver mirror, the performance requriementss such as damage resistant.
