A kind of paint remover for glass lens and its preparation and use method

Abstract

The present invention relates to the technical field of paint remover, in particular to a paint remover for glass lens and its preparation and use method. The paint remover for glass lens is composed of the following raw materials in parts by weight: 5-20 parts of sodium hydroxide, 1-10 parts of Triethanolamine, 5-25 parts of diethylene glycol monomethyl ether, 1-10 parts of N-methylpyrrolidone, 55-70 parts of water. The present invention is an alkaline system, and the alkaline substance sodium hydroxide will not react with sodium silicate in the glass during paint removal, so as to avoid water mist on the glass surface and ensure the paint removal effect; in addition, the raw materials used in the present invention have uniform boiling points. Relatively high, the thermal stability of the prepared product is good, it can be heated to 70 ~ 100 ℃, and the temperature is higher, which helps to quickly remove the paint; the preparation method of the present invention is simple to operate, requires less equipment, and the raw materials are easy to obtain. The preparation is easy, the production cost is low, and it is favorable for popularization and application.

Description

Technical field [0001] The invention involves the field of paint removal technology, especially a glass lens paint and its preparation and use. Background technique [0002] The painting agent is a reagent that can achieve rapid paint and strong paint on the UV oil, optical oil, rubber oil and other paint on aluminum alloy, plastic or hardware.Benefiting to reused, thereby reducing costs and increasing the efficiency of enterprises.The paint dehydent is generally divided into two categories: inorganic paint and organic lacquer. 2 CL 2 Type dehydration agent, CH 2 CL 2 The compatibility of the lacquer is relatively toxic, volatile, combustion, and high cost, which has great physical damage to the operator, and has a damage to the environment.Compared with the organic lacquer, the inorganic lacquer is low, the cost is relatively safe, and the use is relatively safe. After use, it can be used appropriately. [0003] The inorganic lacquer is mainly divided into acidic paint and alkal...

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.
