Example Embodiment

[0012] Example 1: Preparation of raw material mixture

[0013] One day before the curing reaction, by weight, add 900 parts of KA55-10A, 100 parts of KA55-10LA, 1.5 parts of UV-31, 1.0 parts of UV-41, 1.3 parts of B blue, 1.0 parts of R red, and 0.5 parts of V-65 Mix at room temperature to make a mixture of raw materials, the above raw materials are all from Jiangsu Keaoxi Optical Material Technology Co., Ltd. products, KA55-10A, KA55-10LA, UV-31, UV-41, B blue, R red and V-65 All are the company's product codes.

[0014] After the raw materials are mixed, they are heated under stirring in a stirring pot, and the viscosity is tested after the temperature reaches 40°C. After the viscosity reaches 60 mpa.s, use a cold water bath to quickly cool down to 25°C under stirring, and store for later use.

Example Embodiment

[0015] Example 2: Preparation of lens mold

[0016] Assemble the lens upper mold, lower mold and spacer together, and put the rubber ring on the outside. Pay attention to align the injection hole of the rubber ring with the gap of the spacer to facilitate filling.

Example Embodiment

[0017] Example 3: Curing

[0018] After injecting the liquid raw material mixture into the prepared mold, use the cycle as shown in the following table for thermal curing

[0019] Temperature ℃354055607011511560 Running time h Time h 1291.51.532121

[0020] After the curing is over, after the mold is cooled to room temperature, the rubber ring is removed, and the mold is separated to obtain the lens. By adopting the method of the present invention, the lens yield rate reaches 85-90%, which is 8%-10% higher than other companies in the same industry. The rubber ring and mold are cleaned and left for the next reuse. Compared with the conventional tape method, the production cost is greatly reduced.

Abstract

The invention provides a manufacturing method of a polyacrylate resin lens. The manufacturing method comprises the following steps: a) mixing raw materials including 900g of KA55-10A, 100g of KA55-10LA, 1.5g of UV-31, 1.0g of UV-41, 1.3g of B blue, 1.0g of R red and 0.5g of V-65 at the normal temperature to prepare a raw material mixture one day before curing reaction; b) heating the raw material mixture to 40 DEGC and then quickly cooling to 25 DEG C; and c) injecting the liquid-state raw material mixture to a lens mould to perform primary curing. By lowering the amount of V-65 and batching at the normal temperature and quickly cooling, the manufacturing method disclosed by the invention can be used for enabling the prepared raw material mixture not to polymerize and cure, so that the success rate of injection molding is increased, so that the yield of products is increased.

Description

technical field [0001] The invention belongs to the field of optics, and in particular relates to a method for manufacturing a polyacrylic resin lens. Background technique [0002] When acrylic monomers are used as raw materials to produce lenses, the produced lenses show their unique characteristics in terms of raw materials, technology, and quality. In terms of technical performance, they have the characteristics of high performance and high reliability, and are products of high technology. However, the production process of this product is demanding. At present, most companies also use this raw material to produce similar products, and the yield is 5%-10% lower than that of conventional products. The main problem is that during the first curing process of the lens, the glass mold and the lens are separated in advance, resulting in changes in the surface shape of the lens, which seriously affects the optical properties of the lens.
