Embodiment 1

[0047] formula:

[0048]

[0049] The above is the formula for determining the dosage of ingredients per 1000 g of the resin lens of this embodiment.

[0050] Among them, component A (KOC KR70WA) is bis(2,3-epithiopropyl) sulfide, and component B (KOC KR70WAB) is composed of 63.7g dimercaptoethyl sulfide and 1.3g 2-(2-mercaptoethyl) thio)ethanol, component C (KOC KR70WC) is isophorone diisocyanate.

[0051] The resin lens preparation process of the present embodiment is as follows:

[0052] (1) Mold cleaning and assembly: After cleaning the mold, assemble the mold under the condition of 0.6MPa air pressure. Put the mold into the mold cleaning machine for cleaning, and the cleaning process is shown in the table below:

[0053]

[0054] During this process, it is necessary to use a sugar content meter to measure the concentration of the cleaning solution every 2 hours. If the sugar content is lower than the process value of 10-12, add cleaning solution until it meets th...

Abstract

The invention relates to a manufacturing technology for a resin lens with high refraction index and high abbe number. The manufacturing technology is implemented through the following steps: cleaning a mould, and then assembling the mould; adding a component B, a component C and an ultraviolet light absorbent into a mixing barrel, and uniformly mixing; adding a catalyst, a release agent, a blue organic pigment and a red organic pigment, uniformly mixing, adding a component A, and uniformly mixing; filtering, then, injecting raw materials into the assembled mould, and sealing the mould; performing primary solidification on the filled mould, prying the solidified mould, and separating out the mould and molded lenses; trimming the lenses; performing multi-grooved ultrasonic cleaning and secondary solidification on the trimmed lenses; inspecting the lenses subjected to the secondary solidification, and selecting a qualified lens; coating the qualified lens with a film, then, performing hardening solidification on the lens coated with the film; evaporating an antireflection film on the hardened lens. The refraction index of the lens manufactured by adopting the manufacturing technology is 1.693-1.701, and the abbe number of the lens is 34-37.

Description

technical field [0001] The invention belongs to the technical field of lens manufacturing, and in particular relates to a manufacturing process of a resin lens with high refractive index and high Abbe number. Background technique [0002] To the applicant's understanding, the refractive index is the ratio of the speed of light in a vacuum to the speed of light in the material. The higher the refractive index of a material, the greater its ability to refract incident light. The higher the refractive index, the thinner the thickness of the lens, that is, the center of the lens has the same thickness, the same degree and the same material, and the edge of the lens with a high refractive index is thinner than that of a lens with a low refractive index. Common eyeglass lenses on the market are roughly divided into glass sheets, resin sheets, space sheets, etc. according to their materials. Due to its strong impact resistance and unbreakable properties, resin lenses are becoming...
