Glass optical lens paint remover and its preparation and use methods

Abstract

The invention relates to the technical field of paint removers and especially relates to a glass optical lens paint remover and its preparation and use methods. The glass optical lens paint remover comprises, by weight, 5-20 parts of sodium hydroxide, 1-10 parts of triethanolamine, 5-25 parts of diethyleneglycolmonomethylether, 1-10 parts of N-methyl pyrrolidone and 55-70 parts of water. The glass optical lens paint remover is an alkaline system. In paint removal, the alkaline sodium hydroxide does not react with sodium silicate in glass so that water mist on the glass surface is avoided and paint removal effects are guaranteed. The glass optical lens paint remover is prepared from the raw materials having high boiling points, has good heat stability, can be heated to a high temperature of 70-100 DEG C and is conducive to fast paint removal. The preparation method of the glass optical lens paint remover has simple processes, needs less devices, utilizes easily available raw materials, can be operated easily, has a low production cost and is conducive to general popularization application.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a paint remover for glass lenses and a preparation and use method thereof. Background technique [0002] The paint remover is a reagent that can quickly and strongly remove paint from UV oil, varnish, rubber oil and other paint films on aluminum alloy, plastic or hardware glass. Become reusable, so as to reduce costs and improve the efficiency of enterprises. Paint removers are generally divided into two categories: inorganic paint removers and organic paint removers. The main solvent of organic paint removers is mainly CH 2 Cl 2 Type paint remover, CH 2 Cl 2 The type paint remover is relatively toxic, volatile, easy to burn, high in cost, relatively harmful to the operator, and has a destructive effect on the environment. Compared with organic paint removers, inorganic paint removers are low in cost, relatively safe to use, and can be recycled after proper treatment ...

Problems solved by technology

[0003] Inorganic paint strippers are mainly divided into acidic paint strippers and alkaline paint strippers. At present, companies often use acidic paint strippers to remove the patterns, characters, LOGO and other processes of tea mirrors, black mirrors, and gold mirrors. Deep processing, this kind of acidic paint remover is mainly prepared by compounding two raw materials of hydrochloric acid and butanone. Although there are few types of raw materials and convenient manufacture, the paint removal time is more than 8 hours, and the paint removal time is longer , which greatly consumes the time cost of the enterprise. In addition, the main component of the glass is sodium silicate, and the acid may react with the sodium silicate in the glass, and water mist will appear, which will affect the paint removal effect of the lens.
