Abstract
The invention relates to a monomer composition for plastic lens and material for plastic lens with excellent refractive index, light weight, resistance to impact, heat resistance or decoration ability. More specifically, the composition includes diallyl ester oligomer, maleic acid dialkyl ester, diethylene glycol bisallyl carbonate and diallyl adipate.
Description
The present invention relates to be used for the monomer composition of plastic lens.Particularly, the present invention relates to have good specific refractory power, the plastic lens material of in light weight, shock resistance, plasticity, colouring power, especially light stability, with and the manufacturing of plastic lens.
The novel material that searching is used for lens is that industry is paid close attention to always, because the shock resistance of material glass commonly used is poor, and also heavier relatively.When attempting to address the above problem, once made plastic lens with polystyrene, polyoxyethylene glycol diallyl carbonic ether, polycarbonate, modification Phthalic acid, diallyl ester.Yet, although it has good specific refractory power (greater than 1.59) by the lens of polystyrene and polycarbonate manufacturing,, therefore when being shaped, be easy to the optics recurvation because be thermoplastic, be bonded in the insufficient strength on the hard coat film.For addressing the above problem, in EP06905A2, use comprises 15-50% (weight) stylen, the vinylformic acid of 5-40% (weight) and bisphenol A type epoxy resin reaction solution, 5-40% (weight) vinylformic acid and two-tetrabromo-bisphenol type Resins, epoxy reaction solution, and the mixture of 5-20% (weight) Vinylstyrene, diallyl two phenates (dially di phenate), Vinyl toluene and chrorostyrene.Yet this material still lacks thermostability.Another example is the plastic lens of being made by polyoxyethylene glycol two (allyl carbonate), and is in light weight, have good colouring power and shock resistance, but its specific refractory power is 1.5 to the maximum, and the edge of lens can be very thick as a result.Therefore, said lens only can be used for the lens less than-3.00.
As another kind of material, also used the new plastic lens of specific refractory power (〉=1.55).Particularly, a kind of plastic lens that Japanese Patent 53-7787 makes is to be made of diallyl isophthalate and Diethylene Glycol diallyl carbonic ether (by 85: 15 weight ratio).Although the contriver successfully makes lens thinner, still there is the problem of shock resistance difference in they.
In Japanese patent gazette 62-235901 and 64-45412 and Japanese Patent 1-60494, there is same problem always, introduced the multipolymer of forming by modification Phthalic acid, diallyl ester and dibenzyl fumarate in these documents, and the polymkeric substance of forming by Phthalic acid, diallyl ester and methacrylic ester.
In addition, also have some other example, for example Korean Patent 96-013122 proposes a kind of by the plastic lens of molding by the mixture manufacturing of modification ethylene glycol bisthioglycolate (allyl carbonate) and dibenzyl maleate derivative; The plastic lens that Korean Patent communique 1998-023955 proposes is to make by bisphenol type epoxy thing and vinylformic acid being dissolved in the alcohol, adding vinylbenzene or acryl monomer in this mixture, be shaped at last the mixture that makes; And Korean Patent communique 1999-014549 advises a kind of plastic lens, comprises that by molding the mixture of modification Phthalic acid, diallyl ester, zeryloxyalkyl and diethylidene diallyl carbonic ether is made.These plastic lenss have good specific refractory power, plasticity-, colouring power and shock resistance, but light stability is poor.
Therefore, the purpose of this invention is to provide the plastics that are used for optical lens, this optical lens has good optical property such as specific refractory power, thermostability, solvent resistance, in light weight, transparency and light stability.
The invention provides the plastics composite that is used for optical lens, it comprises the polymkeric substance of the Chemical formula 1 representative of (ⅰ) 40-90% (weight); (ⅱ) polymkeric substance of the Chemical formula 2 of 1-30% (weight) representative; (ⅲ) diallyl adipate (diallyadiphate) of 5-30% (weight) or Diethylene Glycol diallyl carbonic ether; (ⅳ) optional a spot of mineral dye and uv-absorbing agent.At this, the examples of polymers of component 1 includes but not limited to following:

6The secondary alcohol residue of alkyl; M is the integer of 0-15.When m=0, the part by weight of formula 1 compound is 10-60% (weight), and during m=1-3, its part by weight is 20-60% (weight), during m=4-10, is 1-40% (weight); M 〉=11 o'clock are 0-20% (weight).

As mentioned above, the resin combination of manufacturing plastic lens of the present invention is included as component 1, component 2, diallyl adipate or the Diethylene Glycol diallyl carbonic ether of certain blending ratio.
Component 1 can be by at 100-200 ℃, 5-14 hour transesterification reaction between Phthalic acid, diallyl ester and the polyvalent alcohol, or 5-14 hour transesterification reaction obtains between dimethyl phthalate and the glycol monomethyl allyl ester.

Wherein m is the integer of 0-15, and therefore, if m=0, the part by weight of component 1 is 10-60% (weight), and during m=1-3, its part by weight is 20-60% (weight), during m=4-10, is 1-40% (weight); M 〉=11 o'clock are 0-20% (weight).
At this, when m=0, promptly part by weight is less than 10%, and it can make viscosity obviously improve, the polymerization disproportionation.And when monomeric compound injected glass mold, air filled cavity was difficult for removing, and produces ropy lens.When m 〉=11, observe similar problem.Therefore, the weight of component 1 is preferably 40-90% (weight), because when at part by weight during less than 40% (weight), specific refractory power is very low, and shock resistance is all very poor when part by weight surpasses 90% (weight).
Component 2 can be passed through at 80-200 ℃, and 5-14 hour transesterification reaction obtains between glycol ester and maleic acid ester, Maleic Acid, Anhydrous ester or the dimethyl maleate.

Except that said components 1 and component 2, also can add diallyl adipate or the Diethylene Glycol diallyl carbonic ether of 5-30% (weight), with the shock resistance of reinforced plastics lens.At this, if this motif material add-on greater than 30% (weight), the specific refractory power of lens reduces.Among the present invention, for making the plastic lens that improves light stability and thermostability, add and be selected from following additive: hydroxyl-4-methoxyl group benzophenone, 2-hydroxyl-3,5-di-tert-pentyl-phenyl benzotriazole, 2,4-two (2, the 4-3,5-dimethylphenyl)-6-(2-hydroxyl-4 n-octyloxy phenyl-1,3, the 5-triazine), 2-(3-hydroxyl-5-otyl phenyl) benzotriazole, 2-[4-(2-hydroxyl-3-dodecyl propoxy-)-4,6-two (2,4-3,5-dimethylphenyl-o-1,3, the 5-triazine)], 2-(2-hydroxyl-benzotriazole-2-phenyl)-p-cresols, 2-(2-hydroxybenzotriazole-2-phenyl)-4,6-two (1-methyl isophthalic acid-phenylethyl) phenol, 2-(2-hydroxyl-3-butyl-5-aminomethyl phenyl)-5-chlorobenzotriazole.
Randomly, also can add small amounts of inorganic pigment or uv-absorbing agent.
Among the present invention, add a small amount of blue pigments and red pigment, make the transparent initial color of lens, and add alcohol seldom, as methyl alcohol, ethanol, butanols, amylalcohol, 2-phenylethyl alcohol or benzyl alcohol.
The stiffening agent that is used for monomeric compound is selected from following: 2,2-azo two (2, the 4-nitrile dimethyl), two-sec.-propyl peroxide pyrocarbonate, two-positive propoxy carbonic ether, two (4-tert-butylcyclohexyl) peroxide pyrocarbonate, t-butyl peroxy pivalate, t-butyl peroxy-2-ethylhexanoate, 1,1-two (t-butyl peroxy)-3,3,5-trimethyl-cyclohexane, t-butyl peroxy neodecanoic acid ester.Stiffening agent is two-sec.-propyl peroxide pyrocarbonate preferably, is the 1-5% of monomer composition weight.
Therefore, the invention provides the monomer composition of the plastic lens that is used to make shock resistance with raising, thermotolerance, thermostability, transparency, especially light stability.
With reference to the following examples, the present invention is described in more detail, these embodiment are not construed as limiting the invention.
