Abstract

The invention discloses a preparation method of a thermal ageing resisting resin lens. The preparation method comprises the following steps: dissolving an antioxygen and a light stabilizer into a solvent; after forming a transparent homogeneous solution, adding the solution into a monomer and dissolving a UV (Ultraviolet) agent; cooling to room temperature and adding an initiator; stirring raw materials at room temperature and under a vacuum condition; after filtering, adding pigment blue and pigment red; continually stirring and vacuumizing under a vacuum condition; filtering the static raw materials again and pouring into a mold; sealing in the mold by utilizing an adhesive tape; putting the mold into a curing furnace, and heating according to a corresponding curing curve and curing for a first time; after finishing, opening the mold and taking out the lens; after washing, turning the lens with certain size and diameter; putting the turned lens into the curing furnace, and heating according to the corresponding curing curve and curing for a second time; after checking that the lens is qualified, packaging and storing. According to the preparation method disclosed by the invention, the thermal ageing resisting performance of the lens is enhanced and the lens does not easily become yellow; a condition that the color of the lens is abnormal is not easy to cause and the service life of the lens is prolonged; the requirement on the light transmission of the lens is met.

Description

technical field [0001] The invention relates to the technical field of resin lenses, in particular to a method for preparing a heat-aging-resistant resin lens. Background technique [0002] In today's society, eye problems are an increasingly serious social phenomenon, such as myopia, astigmatism, and hyperopia. Therefore, glasses have just become the basic tool for solving these problems, thereby become the requisite articles for use in people's daily life. And lens is as the most important component part of glasses, and the quality of its performance directly affects the use effect of glasses. Normally, the warehouse will guarantee a certain amount of inventory after the lens is produced, but if there is a problem with an order, it will cause a large amount of inventory retention. During the storage process, due to the effect of heat and oxygen, if coupled with the The initiator that has time to react, the resin lens will age and cause the color to turn yellow or fade. ...
