Problems solved by technology

The shortcoming of the silver mirror produced by this method is: 1) because the cleaning ability to the surface of the glass base material is weak, so its binding force with the silver layer is relatively poor, and it is easy to come off; 2) the reflectivity of the mirror is low, The reflective layer has weak abrasion resistance

Embodiment 1

[0009] The production method of copper-free silver mirror comprises the following steps:

[0010] 1) Surface cleaning of glass substrates

[0011] Using 70% CeO 2 The polishing powder is ground and polished by 6 disc brushes to make the H of the glass surface 3 o + Ions and Na + The ions are exchanged with each other to form a hydrolyzed compound with the glass; then rinse with pressurized deionized water, and spray the active agent on the surface of the glass substrate; stand for a period of time, and then rinse with pressurized deionized water.

[0012] The above active agent can use SnCl containing 2‰ 2 , 2‰ of HCl, and the rest are active agents of deionized water.

[0013] 2) Spray catalyst solution

[0014] The weight percentage of catalyst solution is composed of: 28% PdCl 2 , 5% Ru, 1% HCl, and the rest are deionized water. Spraying the catalyst solution can increase the adhesion of the silver layer to the glass surface.

[0015] 3) Silver plating layer and pa...

Embodiment 2

[0029] The production method of copper-free silver mirror comprises the following steps:

[0030] 1) Surface cleaning of glass substrates

[0031] Using 73% CeO 2 The polishing powder is ground and polished by 6 disc brushes to make the H of the glass surface 3 o + Ions and Na + The ions are exchanged with each other to form a hydrolyzed compound with the glass; then rinse with pressurized deionized water, and spray the active agent on the surface of the glass substrate; stand for a period of time, and then rinse with pressurized deionized water.

[0032] 2) Spray catalyst solution

[0033] The weight percentage of catalyst solution is composed of: 28% PdCl 2 , 6% Ru, 1.2% HCl, and the rest are deionized water.

[0034] 3) Silver plating layer and passivation agent

[0035] The electroless silver plating stock solution is divided into A agent, B agent, C agent and water. Agent A is made of silver nitrate, ammonia water and deionized water, each accounting for 19% and 2...

Embodiment 3

[0045] The production method of copper-free silver mirror comprises the following steps:

[0046] 1) Surface cleaning of glass substrates

[0047] Using 75% CeO 2 The polishing powder is ground and polished by 6 disc brushes to make the H of the glass surface 3 o + Ions and Na + The ions are exchanged with each other to form a hydrolyzed compound with the glass; then rinse with pressurized deionized water, and spray the active agent on the surface of the glass substrate; stand for a period of time, and then rinse with pressurized deionized water.

[0048] 2) Spray catalyst solution

[0049] The weight percentage of catalyst solution is composed of: 30% PdCl 2 , 5% Ru, 1% HCl, and the rest are deionized water.

[0050] 3) Silver plating layer and passivation agent

[0051] The electroless silver plating stock solution is divided into A agent, B agent, C agent and water. Agent A is made by mixing silver nitrate, ammonia water and deionized water, each accounting for 20% ...

Abstract

The invention provides a copper-free silver mirror which has sharp image and is not easy to fall off, which comprises a glass substrate; wherein, silver layers, mirror primer and mirror finish are arranged on the surface of the glass substrate in sequence; the thickness of the silver layer is 900-1000mg/m. The manufacturing method of the copper-free silver mirror comprises the following steps: 1) using polishing powder containing 70%-75% of CeO2 by weight to polish the surface of the glass substrate, carrying out deionized water rinsing on the surface, spraying active agent, standing for a period of time and carrying out deionized water rinsing again; 2) spraying catalyst solution which consists of the following components by weight percentage: 28-30% of PdC2, 5%-6% of Ru, 1%-1.2% of HC1 and the rest of deionized water; 3) coating silver layer with thickness of 900-1000 mg/m and passivant on the surface of the glass substrate; 4) carrying out deionized water rinsing and then drying; 5) curtaining the mirror primer and mirror finish. The mirror is sprayed with catalyst containing PdCl2 and the passivant containing Snf2 are sprayed rather than cooper layer, therefore, the image is sharper and not easy to fall off.

Description

technical field [0001] The invention relates to a copper-free silver mirror and a production method thereof. Background technique [0002] At present, the production method of silver mirror is as follows: after cleaning and polishing the surface of the glass substrate with detergent powder and tap water, spray the active agent, wait for a period of time and then rinse with deionized water, plate the silver film and then plate copper After the copper layer is stabilized, rinse the excess impurities on the surface of the glass substrate with deionized water, dry the glass surface with a dry blower, and then coat the primer, dry it in an oven, and then coat the top coat. Finished mirror. The shortcoming of the silver mirror produced by this method is: 1) because the cleaning ability to the surface of the glass base material is weak, so its binding force with the silver layer is relatively poor, and it is easy to come off; 2) the reflectivity of the mirror is low, The reflecti...
