preparation example Construction

[0046] The preparation steps of component A are as follows: dissolving the alkoxysilane and the adhesion promoting resin in part of the first solvent, adding the catalyst and the nano-silica colloid solution, and performing a hydrolysis polycondensation reaction to obtain For the first reactant, the first reactant is cooled and the remaining first solvent and the additive are added while cooling, and the component A is obtained by mixing. Further, after adding the remaining first solvent and mixing with the additive, a filtering step is also performed. When filtering, use a 1-5μm precision filter for filtration, which can remove large particles and avoid cracking and falling off of the hardened layer.

[0047] The preparation steps of component B are as follows: dissolving the alkoxysilane and the adhesion promoting resin in part of the second solvent, adding the catalyst and the nano-oxide colloid solution, and performing a hydrolysis polycondensation reaction to obtain the s...

Embodiment 1

[0058] The present embodiment provides an adhesion promoting resin, which is prepared according to the following steps:

[0059] Add 100 parts of propylene glycol methyl ether into a 500ml three-necked flask and raise the temperature to 80°C, slowly dropwise add 10 parts of γ-methacryloyloxypropyl trimethoxysilane, 30 parts of methyl methacrylate, 60 parts of tetramethyl methacrylate A solution composed of hydrogen furfuryl ester and 0.5 part of azobisisobutyronitrile was reacted for 6 hours to obtain an adhesion promoting resin.

Embodiment 2

[0061] The present embodiment provides a lens hardening solution with adjustable two-component refractive index, which is prepared according to the following steps:

[0062] Preparation of component A: 150 parts of γ-(2,3-glycidoxy)propyltrimethoxysilane, 50 parts of phenyltrimethoxysilane, and 30 parts of adhesion promoting resin (made in Example 1) , 200 parts of ethanol was added into a 500ml three-necked flask, 70 parts of silica sol with a solid content of 30% and 10 parts of acetic acid were added under stirring conditions, the temperature was raised to 65°C for 30min, then heated to 80°C, maintained for 2h, and 50°C was added while cooling. 1 part of ethylene glycol butyl ether, stirred for 1 hour, added 5 parts of aluminum acetylacetonate and 0.2 part of BYK333, stirred for 4 hours, and filtered with a 1 μm precision filter to obtain the sun lens plus hard liquid component A.

[0063] Preparation of component B: add 150 parts of γ-(2,3-glycidoxy)propyltrimethoxysilane,...

Abstract

The invention provides a bi-component refractive index-adjustable lens hardening liquid as well as a preparation method and a use method of the bi-component refractive index-adjustable lens hardening liquid. The lens hardening liquid comprises a component A and a component B, the component A comprises the following raw materials in parts by weight: 10-50 parts of a first solvent, 5-30 parts of alkoxy silane, 5-30 parts of a nano silicon dioxide colloidal solution, 3-10 parts of adhesion promoting resin, 0.5-5 parts of a catalyst and 0.1-5 parts of an additive. The component B is prepared from the following raw materials in parts by weight: 10-50 parts of a second solvent, 5-30 parts of alkoxy silane, 5-30 parts of a nano oxide colloidal solution, 3-10 parts of adhesion promoting resin, 0.5-5 parts of a catalyst and 0.1-5 parts of an additive. According to the present invention, the obtained component A has the low refractive index, the obtained component B has the high refractive index, the component A and the component B are easily blended, and the hardening liquid with different refractive indexes can be obtained by adjusting the mixing ratio, such that the hardening liquid can be suitable for various base materials, and has good adhesion to different base materials.

Description

technical field [0001] The present invention relates to the technical field of lenses, in particular, to a lens hardening liquid with adjustable two-component refractive index and a preparation method and use method thereof. Background technique [0002] With the development of the material industry, the materials of sunglasses on the market are more and more abundant. According to the material, including glass material, crystal material and plastic material. The plastic material is not easy to break and has good impact resistance, and gradually replaces other materials to become the mainstream. The plastic materials of sunglasses mainly include resin (CR39), PC, TAC, nylon, polyester (Tritan), AC (acrylic) and so on. Glasses manufacturers will choose different plastic materials to produce lenses based on considerations such as demand and cost. [0003] However, due to poor surface strength, plastic materials are prone to scratches, wear marks, etc. During the manufacturi...
