Embodiment 1

[0041] The present invention is a processing technology for producing special lenses for safe driving, and the processing technology includes the following steps:

[0042] (1) Process resin semi-finished products into resin substrates or conduct visual inspection, pretreatment, and clamping of resin substrates;

[0043] (2) Add 0.08% VL462 to the top coating hardening liquid MP7110 of SDC, stir well until it is completely dissolved, then add it into the hardening liquid tank in the hardening machine and circulate it with a 5 μm filter element for 24 hours;

[0044] (3) The lens is hardened by an automatic hardening machine. The pulling speed of the solution prepared in step (2) is set at 1.5mm / s. After the pulling is completed, it is placed in an oven at 115°C for 2.5 hours to cure;

[0045] (4) The lens cured in step (3) is transferred to a vacuum coating machine to be coated with a 585nm narrow-band visible light reflective coating layer.

Embodiment 2

[0047] The present invention is a processing technology for producing special lenses for safe driving, and the processing technology includes the following steps:

[0048] (1) Process resin semi-finished products into resin substrates or conduct visual inspection, pretreatment, and clamping of resin substrates;

[0049] (2) Add 0.14% VL462 to the top coating hardening solution MP7110 of SDC, stir well until it is completely dissolved, then add it to the hardening solution tank in the hardening machine and circulate it with a 5 μm filter element for 24 hours;

[0050] (3) The lens is hardened by an automatic hardening machine. The pulling speed of the solution prepared in step (2) is set at 1.5mm / s. After the pulling is completed, it is placed in an oven at 115°C for 2.5 hours to cure;

[0051] (4) The lens cured in step (3) is transferred to a vacuum coating machine to be coated with a 585nm narrow-band visible light reflective coating layer.

Embodiment 3

[0053] The present invention is a processing technology for producing special lenses for safe driving, and the processing technology includes the following steps:

[0054] (1) Process resin semi-finished products into resin substrates or conduct visual inspection, pretreatment, and clamping of resin substrates;

[0055] (2) Add 0.2% VL462 to the top coating hardening solution MP7110 of SDC, stir well until it is completely dissolved, then add it into the hardening solution tank in the hardening machine and circulate it with a 5 μm filter element for 24 hours;

[0056] (3) The lens is hardened by an automatic hardening machine. The pulling speed of the solution prepared in step (2) is set at 1.5mm / s. After the pulling is completed, it is placed in an oven at 115°C for 2.5 hours to cure;

[0057] (4) Apply a layer of UV adhesive evenly on the front surface of the lens after hard coating in step (3) with a spin coater, then adhere the polarizing film to the surface of the lens, a...

Abstract

The invention provides a processing technology for production of a glasses lens specially used for safe driving. The processing technology includes the steps of: 1) processing a resin semi-product to form a resin substrate, or performing appearance inspection, pretreatment and fixture mounting to the resin substrate; 2) adding 0.01-5% of an additive to a top-coating hardening liquid MP7110 from SDC Technologies, stirring the mixture until complete dissolution, adding the solution into a hardening liquid groove of a hardening machine, and performing circulation with a filter core being 1-10 [mu]m for 24 h; 3) performing hardening film-coating to the lens through the auto-hardening machine, wherein the pulling speed of the solution is set as 1.5 mm / s, and after the pulling operation, curing the coating in a drying box for 2.5 h at 115 DEG C; and 4) moving the solidified lens into a vacuum film coating machine to coat the lens with a 585 nm narrow-band visible light reflecting film layer. The glasses lens can keep driving safe and comfort in both day and night and comprehensively protects eyes.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing, in particular to a processing technology for producing special lenses for safe driving. Background technique [0002] Lenses used in daily life can not only correct vision and protect eyes, but also serve as decorations. There are three common types of glasses, namely myopia glasses, farsighted glasses (reading glasses) and sunglasses (sunglasses). In addition to these types of glasses, there are also sports goggles, TV computer goggles and driver goggles. [0003] Resin lenses have very complex cross-linking and conjugated bonds inside. Although polycarbonate lenses can block harmful UV light, most resin lenses with other structures cannot block harmful ultraviolet rays, and the damage of ultraviolet rays to glasses cannot be underestimated. At present, the mainstream anti-UV lenses on the market can only block ultraviolet rays in the lower band of 100-400nm, which is far behind the...
