Abstract

The invention mainly relates to a combination for preparing a resin lens with good safety. The combination is prepared by adopting diisocyanate, polyatomic alcohol, catalyst and ultraviolet absorber, an internal release agent and a color matching agent according to formula dose; and the invention also relates to a method for preparing the resin lens by utilizing the combination. The prepared resin lens has the advantages of being high in hardness, light in mass and radiation resistant, and can meet the requirements of glass wearers on safety and comfortableness.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a composition for preparing lenses with good safety and a method for preparing lenses by using the composition. Background technique [0002] According to statistics, myopia patients in the world account for about 30% to 40% of the total number, so glasses have become an indispensable article for a large part of people's daily life. The lens is the key component of the glasses, and its performance will directly affect the use effect of the glasses. In the 1990s and before, spectacle lenses were generally made of glass materials, which were often fragile and heavy, which greatly affected the safety and comfort of myopia patients wearing glasses, so they were gradually replaced by resin lenses. [0003] The current ordinary resin lenses are made of diethylene glycol propylene carbonate (ADC) material, or diallyl isophthalate, diallyl terephthalate, dibutyl maleate and ADC Monom...
