Demolding agent for glass panel vacuum film plating

Abstract

The invention discloses a demolding agent for glass panel vacuum film plating. The demolding agent comprises the following components in percentage by weight: 15-20% of cosolvent, 8-10% of builder, 4-6% of permeating agent, 9-12% of chelating agent, 7-11% of organic base, and the balance of water, wherein the permeating agent comprises the following components in percentage by weight: 1-2% of alkyl polyglucoside, 1-2% of dodecyl dimethyl betaine, and 1-2% of succinic acid di-sec-octyl ester sulfonate. Compared with the prior art, the demolding agent applies the effects of wetting, emulsification, compatibilization, dispersion and washing of all the components to achieve the multifunctional compound performance, is high in dirt removing capacity on various vacuum plating films and adhesive films, is thorough in removal, is free of corrosion, scratch and rubbing on glass, is low in reject ratio of continuous operation, is excellent in stability, is nearly neutral without poison, harm, excessive erosion and hydrogen permeation, achieves the biodegradability, improves the dirt removing efficiency, and reduces the environmental pollution.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a release agent for vacuum coating of glass panels. Background technique [0002] Glass coating technology has developed rapidly, such as evaporative vacuum coating, magnetron sputtering vacuum coating, electric float coating, thermal spraying, etc. Computer casings often use coated glass panels, and the quality of the coating is high. When it is actually used in product manufacturing, it is easy to produce defective products of vacuum coating, either due to the needs of the manufacturing process or due to improper use. The coating on the coated glass needs to be completely removed. [0003] The coating of glass panels is usually to form indium tin oxide or indium tin alloy coating film on the surface of glass substrate through vacuum coating process, and then coat one or more metals before or / and after indium tin oxide or indium tin alloy coating film Layers such as one...

[0002] Glass coating technology has developed rapidly, such as evaporative vacuum coating, magnetron sputtering vacuum coating, electric float coating, thermal spraying, etc. Computer casings often use coated glass panels, and the quality of the coating is high. When it is actually used in product manufacturing, it is easy to produce defective products of vacuum coating, either due to the needs of the manufacturing process or due to improper use. It is necessary to completely remove the coating on the coated glass

[0003] The coating of glass panels is usually to form indium tin oxide or indium tin alloy coating film on the surface of glass substrate through vacuum coating process, and then coat one or more metals before or / and after indium tin oxide or indium tin alloy coating film Layers such as one or more alloys or oxides of aluminum, nickel, molybdenum, gold, titanium, silver, antimony or copper, thereby changing the glass's radiation rate, reflectivity, absorptivity and transmittance to sunlight and heat. High efficiency and other properties or endow the glass surface with special properties such as conductivity and self-cleaning; after that, it will form protective layers of ink, paint and other adhesive films through PVD magnetron sputtering physical repair, etc. The physical and chemical properties of the glass substrate adhesive film are relatively stable and It is not easy to remove the film, and the coating is relatively strong. Traditionally, strong acid and alkali are used to remove bad vacuum coatings, which is likely to cause corrosion of the glass and pollute the environment. The removal of glass coatings also has weak decontamination ability and high cost. High, easy to oxidize the film layer, low cleaning efficiency and other problems
