Description

Transparent molded article and manufacture method thereof

Technical field

The present invention relates to the transparent molded article and the manufacture method thereof of lens etc.The invention particularly relates to the transparent molded article and the manufacture method thereof that are suitable for optical applications, this transparent molded article comprise the transparency and with the release property polyureas good, that in its molecule, have urethane bond of shaping dies.In addition, the invention still further relates to the optics that on polyurethaneurea polymer substrate (substrate), has antireflection film.

Background technology

With the glassy phase ratio, plastics in light weight, be difficult for breaking and dyeing easily, therefore be applicable to optical applications based on the various lens of glasses lens etc.As its representational example, can enumerate poly-diethylene glycol bis-allyl carbonate and polymethylmethacrylate.Yet the specific refractory power of these plastics is all low, has only about 1.50, and its proportion is also about more than 1.2.Therefore, for example using the occasion of glasses lens, the number of degrees are high more, and near the thickness the lens centre is just thick more, and the thickness of rims of the lens also must thicken, and this point will be damaged the superiority of the light plastics of the amount of being called as.In addition, though with the glassy phase ratio, these plastics are difficult to break, and require the more difficult disruptive cry of plastics also strengthening.According to these requirements, light and be difficult to the feature of disruptive plastics for performance amount better, people have begun polycarbonate that obtains by injection forming or the polythiourethane that obtains by cast poymerization are used for optical applications.Though its intensity of this polycarbonate is very big, it has the common drawback of injection forming material, just its poor solvent resistance.On the other hand, though polythiourethane do not find to resemble above-mentioned the common drawback of injection forming material, just less than polycarbonate, this is present present situation aspect intensity.

Therefore, for fear of the common drawback of injection forming material, people wish to develop a kind of can obtain by cast poymerization and material with the intensity that can be equal to polycarbonate.As the material with feature like this, known have by terminal prepolymer of the isocyanic ester that has urethane bond at its intramolecularly and aromatic diamine are carried out the material (U.S. Pat 5962617, US 6127505) that cast poymerization obtains.In addition, become known for making and contain isocyanate-reactive polymkeric substance, sterically hindered aromatic diamine and as the manufacturing process (special fair 3-39533 communique) of the resin combination of the fatty acid zinc salt of internal mold release.

Yet disclosed material in No. 5962617 communiques of U.S. Pat, used aromatic diamine are solid at normal temperatures, and its polyreaction is carried out soon, therefore generate the dissolved residue, the result causes the transparency of the molding that obtains poor, and this is the problem that exists.On the other hand, disclosed material in No. 6127505 communiques of U.S. Pat, itself has enough transparencys as optical material.But when making, in that become can not be satisfactory aspect the release property of major issue by cast poymerization.

Therefore, present inventors are for disclosed polyurethane-urea based material in No. 6127505 communiques of U.S. Pat, have studied situation about release property being improved when using in that itself and various internal mold release are merged.Yet, distinguish, at the general releasing agent that silicone-based, fluorine system, metal-salt system etc. are used as plastics or when the spy opens that disclosed acid phosphatase alkyl ester uses as internal mold release in flat 1-163012 communique and the clear 64-45611 communique of Te Kai, exist because the problem that the smudgy transparency that causes reduces, perhaps have intensity to reduce maybe can not to obtain the problem of enough release properties etc.And then present inventors have also studied in the fair 3-39533 communique of spy disclosed fatty acid zinc to the improvement situation of release property.Disclosed shaping thing in the fair 3-39533 communique of spy is owing to himself be opaque, and its demolding performace has reached enough degree, even contain fatty acid zinc, and also not influence fully.But, because fatty acid zinc exists as crystallization, therefore produced scattering of light in molding, so, in fact be impossible as the internal mold release of transparent formed body and function fatty acid zinc.

Disclosed material is the polyureas that can carry out cast poymerization and have urethane bond at its intramolecularly in No. 6127505 communiques of U.S. Pat, though it has the intensity that can be equal to polycarbonate, but as mentioned above, it is as general internal mold release, can not obtain enough release properties when cast poymerization, this is the problem that exists.

Summary of the invention

Therefore, first purpose of the present invention provides a kind of transparency and the molding that be suitable for optical applications and the manufacture method thereof all good with the release property of shaping dies.

In addition, a kind of material that adopts aromatic diamine to design as raw material is disclosed in No. 6127505 communiques of U.S. Pat, though this material itself has enough transparencys as optical material, but owing to the oxidation of aromatic diamine causes producing when the polymerization light and heat (particularly ultraviolet ray), cause the product flavescence, this is a big shortcoming.

In No. 6127505 communiques of U.S. Pat, put down in writing,, used UV light absorber, photostabilizer or antioxidant, but wherein only enumerated some universal products, do not mention its detailed recipe quantity etc. in order to remedy this shortcoming.Its result does not have to obtain countermeasure satisfied in practicality, the big problem of the product flavescence that light and heat caused when still existing owing to polymerization.

Therefore, second purpose of the present invention provide the transparency good, be not easy because light and heat cause the product flavescence, are suitable for the transparent molded article and the manufacture method thereof of optical applications, this transparent molded article is to carry out the material that cast poymerization obtains by isocyanic ester end prepolymer and the aromatic diamine that intramolecularly is had urethane bond.

On the other hand, in order to improve the reflection behavior of surface of the optics of being made by synthetic resins, can be coated with antireflection film on the surface of synthetic resins, this point is known.For example, open in the clear 56-116003 communique the spy and to disclose the optics that is provided with antireflection film, these parts, in turn have by SiO from substrate side on the CR-39 resin as substrate with CR-39 (diethylene glycol bis-allyl carbonate) resin ₂The thickness that constitutes is the bottom of 1.5 λ, by ZrO ₂Layer and SiO ₂The common total thickness that constitutes of the film two-layer of equal value that layer constitutes is about the first layer of 0.25 λ; By ZrO ₂The thickness that constitutes is about the second layer of 0.50 λ; By SiO ₂The 3rd layer of about 0.25 λ of thickness that constitutes; Constitute antireflection film jointly by these three layers.

Yet different with glass substrate, resin substrates can cause that when evaporation underlayer temperature increases, and can not form antireflection film.Therefore, by evaporation form for example by ZrO ₂Not talkative its thermotolerance of layer that constitutes is sufficient.And, by ZrO ₂The layer that constitutes is along with the prolongation of time, and its thermotolerance also causes reducing greatly easily.The thermotolerance of such antireflection film integral body is inadequate, and, can cause the optics that thermotolerance reduces greatly along with the prolongation of time, for example when using, tend to produce the problem in the practicality as glasses lens.This be because, when glasses lens is fit into plastic spectacle-frame, picture frame must be heated, this heat also can conduct to glasses lens simultaneously.For the low antireflection film of thermotolerance, owing to the difference of thermal expansivity etc. causes cracking (be full of cracks).

As the method that is used to solve this class thermotolerance problem, for example open to disclose in the flat 2-291502 communique on high refractive index layer, to have to have used and contain Ta the spy ₂O ₅, ZrO ₂And Y ₂O ₃Vapor-deposited film antireflection film optics and be used to form and contain Ta ₂O ₅, ZrO ₂And Y ₂O ₃The evaporation composition of vapor-deposited film.

Particularly in eyewear art, people require to develop new optics, and this optics as substrate, and has the as far as possible little antireflection film of degree that the fine and thermotolerance of thermotolerance reduces with plastic lens.

Therefore in addition, compare with glass substrate, resin substrates has elasticity, and the antireflection film that provides film toughness high is provided, even afterburning and make the occasion of substrate deflection to this undercoat, also do not worry cracking on this antireflection film.

Therefore, the 3rd purpose of the present invention provides optics, this optics uses the material that is made of polyurethaneurea polymer as substrate, and have matched with substrate, thermotolerance is good, film toughness is high and the little antireflection film of degree that reduces along with its thermotolerance of prolongation of time.

Present inventors are in order to develop a kind of transparency that neither contains disclosed polyurethane-urea based material in infringement above-mentioned U.S. Pat No. 6127505 communiques, can give again good release property suitable optical applications material and further investigate.Found that, by by the composition that contains the terminal prepolymer of specific isocyanic ester, contain the composition of specific aromatic diamine and contain the phosphate monoester that has ad hoc structure separately and composition that the ingredients of a mixture of phosphodiester constitutes is cast and solidified the optical material that obtains and is suitable for above-mentioned purpose, so far just finished first technical scheme of the present invention.

In addition, present inventors are for disclosed in No. 6127505 communiques of above-mentioned U.S. Pat, carry out the material that cast poymerization obtains by terminal prepolymer of the isocyanic ester that intramolecularly is had urethane bond and aromatic diamine and carried out deep research, its objective is in order to develop a kind of transparency of neither damaging this material, can give the material of the suitable optical applications of good oxidation (anti-flavescence) again to it.Found that, by being that the composition that becomes to be grouped into of peroxide decomposer is cast and solidified the optical material that obtains and is suitable for above-mentioned second purpose with containing phosphorus, so far just finished second technical scheme of the present invention by the composition that contains the terminal prepolymer of specific isocyanic ester, the composition that contains specific aromatic diamine.

The 3rd technical scheme

The optics of the present invention's the 3rd technical scheme is the optics that has antireflection film on the polyurethaneurea polymer substrate directly or indirectly, and especially, above-mentioned antireflection film is the multi anti reflection coating that contains 1/2 λ layer.

Above-mentioned 1/2 λ layer is characterised in that it has the multilayer high refractive index layer that contains niobium oxides at least and is disposed at the layer that the silicon-dioxide between these high refractive index layers is formed.

Usually, antireflection film is counted in turn from substrate one side and is made of following each layer, that is: 1/4 λ layer (being equivalent to intermediate-index layer)+1/2 λ layer (being equivalent to high refractive index layer)+1/4 λ layer (being equivalent to low-index layer); Perhaps, 1/4 λ layer (being equivalent to intermediate-index layer)+1/4 λ layer (being equivalent to intermediate-index layer)+1/2 λ layer (being equivalent to high refractive index layer)+1/4 λ layer (being equivalent to low-index layer); Perhaps, 1/4 λ layer (being equivalent to intermediate-index layer)+1/4 λ layer (being equivalent to high refractive index layer)+1/4 λ layer (being equivalent to low-index layer).But, the 3rd kind of structure, because the specific refractory power of its substrate or hard coat is about below 1.8, the antireflection wavelength region may is narrow and small, therefore, as the optics of the present invention's the 3rd technical scheme, is more preferably the 1st kind and the 2nd kind of structure.

In the membrane structure of the antireflection film that optics has of the present invention's the 3rd technical scheme, the 1/2 λ layer suitable with above-mentioned high refractive index layer is by the multilayer high refractive index layer that contains niobium oxides at least and be arranged between these high refractive index SiO as the low-refraction material layer ₂Layer constitutes.

More particularly, 1/2 above-mentioned λ layer can have following structure.SiO should be described ₂If the thickness of layer is less than 0.02 λ, then the effect of intensity raising diminishes, therefore, in the scope that this situation does not take place, also can be by increasing the number of plies.In addition, herein, so-called high refractive index layer is meant the high refractive index layer that contains niobium oxides at least.

(1) high refractive index layer-SiO ₂Layer-high refractive index layer

(2) high refractive index layer-SiO ₂Layer-high refractive index layer-SiO ₂Layer-high refractive index layer

(3) high refractive index layer-SiO ₂Layer-high refractive index layer-SiO ₂Layer-high refractive index layer-SiO ₂Layer-high refractive index layer

With SiO ₂Layer is compared, and is all relatively poor as the structural strength and the thermotolerance of the metal oxide layer of high refractive index layer, and therefore, for 1/2 λ layer as the thickest high refractive index layer, its intensity and thermotolerance all have the tendency of reduction.

As the 3rd technical scheme of the present invention, the metal oxide layer as high refractive index layer is divided into multilayer, make the less thick of the first layer, and between each layer, clip one deck intensity and all higher SiO of thermotolerance ₂Layer so just can improve the intensity of 1/2 λ layer.

When above-mentioned high refractive index layer only contains the occasion of niobium oxides, and in the occasion that except niobium oxides, also contains zirconium white and/or yttrium oxide, can have same composition at the multilayer high refractive index layer of each technical scheme, also can have different separately compositions.In addition, in each technical scheme, the thickness of multilayer high refractive index layer can be identical or different, but wish that the difference of thickness is as far as possible little.Because it is the thinnest that the thickness of high refractive index layer is become, and can form a kind of high refractive index material layer that does not have optics heterogeneity phenomenon.

In addition, SiO ₂The thickness of layer is preferably 0.02 λ～0.15 λ.SiO ₂The thickness of layer is as long as more than 0.02 λ, just can obtain to improve fully the effect of the intensity of 1/2 λ layer, and need only below 0.15 λ, just can keep high refractive index.

The high refractive index layer of above-mentioned formation 1/2 λ layer contains niobium oxides (Nb ₂O ₅).And then the high refractive index layer of above-mentioned formation 1/2 λ layer is except containing niobium oxides (Nb ₂O ₅) outside, can also contain zirconium white (ZrO ₂) and/or yttrium oxide (Y ₂O ₃).

Above-mentioned high refractive index layer is that benchmark preferably contains with the gross weight of this layer: niobium oxides 90～100 weight %, zirconium white 0～5 weight % and yttrium oxide 0～5 weight %.When the high refractive index layer of above-mentioned formation 1/2 λ layer only by niobium oxides (Nb ₂O ₅) occasion that constitutes, and at niobium oxides (Nb ₂O ₅) in contain zirconium white (ZrO ₂) and/or yttrium oxide (Y ₂O ₃) occasion, be difficult to produce absorbing phenomenon, thereby become the high layer of perviousness.But, if niobium oxides (Nb ₂O ₅) less than 90 weight %, then be difficult to obtain high refractive index, zirconium white (ZrO ₂If) surpass 5 weight %, then cause thermotolerance to reduce easily, and yttrium oxide (Y ₂O ₃If) surpassing 5 weight %, acid resistance has the tendency of reduction.

In addition, in the evaporation composition of the present invention's the 3rd technical scheme, in the scope of not damaging above-mentioned effect, also can add into aluminum oxide (Al ₂O ₃), tantalum oxide (Ta ₂O ₅), titanium oxide (TiO ₂) metal oxide that waits.

1/4 λ layer (being equivalent to intermediate-index layer) of the multi anti reflection coating of the present invention's the 3rd technical scheme does not have particular determination, for example can be above-mentioned high refractive index layer+SiO ₂Layer, in compositions such as above-mentioned niobium oxides, add aluminum oxide (Al ₂O ₃) and the high refractive index layer+SiO of formation ₂Layer or known high refractive index oxide layer (ZrO for example ₂, Ta ₂O ₅, TiO ₂, Nb ₂O ₅)+SiO ₂Layer etc.In addition, not having particular determination as 1/4 λ layer (being equivalent to low-index layer), for example can be SiO ₂Layer or MgF ₂Layer etc.But, consider from the intensity aspect, preferably SiO ₂Layer.Not having particular determination as bottom, for example can be SiO ₂The layer, by SiO ₂With Al ₂O ₃The mixture layer, metal level (Nb, Ta, Cr etc.), the SiO that constitute ₂Layer+metal level+SiO ₂Layer, SiO ₂Layer+metal oxide layer+SiO ₂Layer etc.

Above-mentioned antireflection film can form as follows, that is: with niobium oxides, zirconium white and yttrium oxide (as required, can also be with oxide compound (aluminum oxide, tantalum oxide and titanium oxide etc.)) powder sintered, make the sintered compact that is obtained produce the steam of mixed oxide, and the evaporant of generation is separated out on substrate.

Above-mentioned high refractive index layer preferably forms as follows, that is: with niobium oxides (Nb ₂O ₅) powder, zirconium white (ZrO ₂) powder, yttrium oxide (Y ₂O ₃) powder mixes (sometimes these powder being called " mixed powder " simply hereinafter), with the pressurization of these powder, use then electron beam for example with the pressurized powder heating that obtained so that evaporant precipitate on the substrate, thereby form above-mentioned high refractive index layer.In addition, be more preferably after pressurization and carry out sintering, and then use the pill shape sintered compact that is obtained to carry out evaporation, more a step shortens the evaporation time like this.The variation that the content of each oxide compound can be done to suit according to the composition of formed high refractive index layer in mix powder and the sintered compact.

With in the past by sintering ZrO ₂And the evaporation composition that obtains is compared, and contains Nb by handle ₂O ₅Powder, ZrO ₂Powder and Y ₂O ₃The mixed powder sintering of powder and the evaporation composition that obtains can shorten the formation time of vapor-deposited film, thus high productivity can be obtained.

The evaporation composition of above-mentioned 3 compositions is described below simply.

Forming under the situation of evaporation raw material by niobium oxides separately, when with electron beam gun heating pill, can produce sputter.Can produce micropartical and be attached to detrimentally affect on the lens face when sputter, this just becomes the reason that produces substandard products.In addition, be easy to generate the phenomenon of film painted (absorption), and the resistance to chemical reagents of acid resistance, alkali resistance etc. also there is the tendency that weakens.In order to overcome these shortcomings, can merge and use ZrO ₂And Y ₂O ₃

Take place only containing the pill of niobium oxides with electron beam gun heating to tend to take place sputter when overheated, this sputter just becomes rete peels off with impurity and adheres to the reason that waits, and interpolation ZrO ₂Have the effect that alleviates sputter, therefore be applicable to the vapor-deposited film that forms stabilizing quality.
