Description
Technical field
The present invention relates to a kind of preparation method of resin monomer, specifically a kind of high adhesion strength optical resin monomer and preparation method thereof.
Background technology
In recent years, optical resin lens at home and abroad on glasses market demand increasing, resin lens is compared with glass mirror, has that quality is light, shock-resistant, dyeing behavior, is easy to the advantages such as processing.Middle high refractive index optical resin lens more obtains user's favor with high transmission rate, anti-ultraviolet, the distinctive advantage such as ultra-thin.Usually, it is high refractive index that the specific refractory power of take in the eyeglass industry reaches more than 1.60, and specific refractory power reaches 1.56 for middle specific refractory power, and specific refractory power is being low-refraction below 1.56.At present, very common for the production of the preparation of the optical resin monomer of low-refraction eyeglass, but be not still very ripe for the production of the technology of preparing of the optical resin monomer of middle high refractive index eyeglass, domesticly in many eyeglasses manufacturer, all need dependence on import; Although still have at present the preparation technology of high refractive index lens optical resin monomer in some, resin monomer adds the eyeglass aberration after the pigment moulding larger, and qualification rate is not high, and colour of lens stability is bad, and qualification rate is low.As everyone knows, the resin lens shortcoming has: surface abrasion resistance power, and anti-chemical capacity is poorer than glass, and surface is cut easily, often needs to improve by film coating method, has increased use cost.
Summary of the invention
Technical problem to be solved by this invention is, the shortcoming existed for above prior art, a kind of high adhesion strength optical resin monomer and preparation method thereof is proposed, can obtain higher adhesion strength when high refractive index in can guaranteeing, and add the eyeglass aberration after the pigment moulding very little, qualification rate is high.
The technical scheme that the present invention solves above technical problem is:
A kind of high adhesion strength optical resin monomer, the weight part of its each component is:
Dimethyl terephthalate (DMT) 21-23
Propylene glycol 3-5

The preparation method of aforesaid high adhesion strength optical resin monomer, after oligopolymer prepares by above step, by proportioning, oligopolymer, dimethyl terephthalate (DMT), propylene glycol, vinylcarbinol, CR-39, dibutyl maleate, tetramethylolmethane four mercaptoacetates, bismaleimides body and diphenylmethanediisocyanate are added to mixing kettle, react 5-7 hour, obtain the high adhesion strength optical resin monomer of thick liquid nano after the adjustment refractive index.
In order to guarantee that resin monomer can obtain higher adhesion strength when having middle high refractive index, the inventor conducts in-depth research, after adding tetramethylolmethane four mercaptoacetates, bismaleimides body and mixtures of diisocyanates and diphenylmethane, the adhesion strength of the eyeglass that this alicyclic monomer is made is significantly improved, by detecting its specific refractory power, discovery is along with the difference that adds tetramethylolmethane four mercaptoacetates, bismaleimides body and each content of diphenylmethanediisocyanate, and specific refractory power can have different impacts; The inventor finds through research, and tetramethylolmethane four mercaptoacetates, bismaleimides body and mixtures of diisocyanates and diphenylmethane add when more, and adhesion strength increases, non-friable, but specific refractory power can descend; Tetramethylolmethane four mercaptoacetates, bismaleimides body and mixtures of diisocyanates and diphenylmethane add when less, and monomer viscosity is high, and the eyeglass difficulty is done, and adhesion strength can't improve; In addition, when oligopolymer is more, eyeglass solidifies difficult, and eyeglass is very crisp; By deep test, the inventor has finally determined above each component concentration, can obtain higher adhesion strength when high refractive index in can guaranteeing, and add the eyeglass aberration after the pigment moulding very little, and qualification rate is high, thereby has completed the present invention.
The technical scheme that the present invention further limits is:
Aforesaid high adhesion strength optical resin monomer, step (iii) in, the thermo-stabilizer added is CAS 3287-06-7, CAS 522-21-1, CAS 12141-20-7, CAS 16038-76-9 or CAS 26544-22-9.
Aforesaid high adhesion strength optical resin monomer, step (iv) in, the stablizer added is CAS 100-51-6 or CAS 75-08-1.
The invention has the beneficial effects as follows: product of the present invention is during for the production of resin lens, the refractive index that makes to guarantee resin lens reach 1.56 and more than, can also obtain higher adhesion strength when guaranteeing high index, after testing, most of resin lens adhesion strength friction haze value (Hs) of making is 0.2-0.25, have even lower than 0.2, adhesion strength is good; In addition, product of the present invention is more stable than like product character, adds the eyeglass aberration after the pigment moulding very little, and qualification rate is high, and colour of lens stability is better, and test does not change the high 5-10% of the more domestic like product of qualification rate after adjusting substantially.
