Abstract

The invention discloses a preparation method of a high shock strength optical resin monomer, which comprises the following steps of: adding 100 parts by mass of acetyl triethyl citrate, 24-28 parts bymass of allyl alcohol and 1.2-1.8 parts by mass of calcium hydroxide into an R-01 reaction kettle, adding 100 parts by mass of purified material after a reaction is finished, 10-15 parts by mass of 1,4-cyclohexanediol and 0.1-0.15 parts by mass of antimonous oxide into an R-01 reaction kettle, heating to 160 DEG C for reaction, transferring 100 parts by mass of material after the reaction, 5-8 parts by mass of Columbia resin, 5-6 parts by mass of dibutyl maleate, 7-8 parts by mass of dioctyl maleate, 2-3 parts by mass of benzyl alcohol and 12-15 parts of triphenyl phosphite into an R-04 mixing kettle, and performing stirring and mixing for 45-60min to form viscous liquid. A refractive index of a resin lens reach above 1.56 when the monomer is used for producing the resin lens, and at thesame time, the monomer further has higher impact strength.

Description

technical field [0001] The invention relates to a preparation method of a high impact strength optical resin monomer. Background technique [0002] Compared with inorganic glass lenses, optical resin lenses have become more and more popular among consumers due to their own advantages, such as light weight, good toughness, and low price. [0003] Generally, in the lens industry, the refractive index is above 1.60 as the high refractive index, the refractive index is 1.56 as the medium refractive index, and the refractive index is below 1.56 as the low refractive index; [0004] At present, the preparation technology of optical resin monomers for the production of medium and high refractive index lenses is still not very mature, and it is often difficult to achieve uniform refractive index and impact resistance. Contents of the invention [0005] Object of the invention: The object of the invention is to provide a method for preparing a high-impact-strength optical resin mo...
