Abstract

The invention provides environment-friendly refraction liquid. One or more of propylene glycol and beta-bromethylene benzene are used as the refraction liquid. The propylene glycol and the beta-bromethylene benzene which are common food or cosmetic raw materials and are non-toxic, innocent, safe and environment-friendly are used as the refraction liquid, so that the refraction liquid is prevented from damaging human bodies of testing personnel. The environment-friendly refraction liquid is stable, has the advantages of high dissolving performance, high viscosity, high adsorption capacity, light color, high light transmission performance and the like, and has low cost compared with that of the conventional refraction liquid.

Description

technical field [0001] The invention relates to an environment-friendly refraction liquid. Background technique [0002] Refractive fluids with different refractive indices are often used in optical glass inspection. The refraction fluid currently used is mainly composed of brominated naphthalene, diiodomethane, arsenic sulfide and other substances. These organic substances have certain toxicity, and some of them are even highly toxic. Due to the high frequency and large amount of refraction fluid used in the testing of glass and its products, it has great harm to the respiratory tract and skin of the testers, and seriously affects the health of the testers. At the same time, the refraction fluids used in the past also have disadvantages such as easy volatilization, poor solubility, dark color, and poor light transmission. Contents of the invention [0003] The technical problem to be solved by the invention is to provide an environment-friendly refraction fluid. [000...
