Description

Thermoplastic resin composition, molded body, method for producing thermoplastic resin composition, and method for improving transmittance

[0001] The present invention relates to a thermoplastic resin composition, etc. In particular, the present invention relates to a thermoplastic resin composition suitable for optical materials, a molded article containing the thermoplastic resin composition, a method for producing the thermoplastic resin composition, a method for improving transmittance, etc.

[0002] Conventionally, additives such as antioxidants and mold release agents have been added to thermoplastic resins to ensure stability and releasability during processing. For example, it is known that adding an antioxidant to a resin improves stability during processing (see, for example, Patent Documents 1 and 2). However, the addition of these additives can impair the inherent performance of the resin. For example, in thermoplastic resins used as optical materials, the addition of additives can reduce transmittance in the short wavelength range, which is extremely important.

[0003] Even a slight change in the transmittance of a thermoplastic resin used as an optical material in the short wavelength region can have a significant impact on the product that it is put into practical use. For this reason, there has been a demand for a resin composition that can maintain the original transmittance of a thermoplastic resin used as an optical material even after commercialization, but no resin composition that can reliably suppress changes in transmittance has been realized.

If the proportion of the structural unit (b) relative to the total of all structural units of the acrylic resin is less than 10%, the heat resistance of the acrylic resin may decrease and the dimensional stability in a high-humidity environment may decrease, which is not preferable.

[0082] The acrylic resin may contain structural units other than the structural units (a) and (b) to the extent that the optical properties are not impaired. Such structural units are not particularly limited, but examples thereof include structural units derived from acrylonitrile, acrylic acid, methacrylic acid, maleic anhydride, phenylmaleimide, cyclohexylmaleimide, etc.

[0083] The method for producing the acrylic resin is not particularly limited, but for example, a method in which a (meth)acrylic acid ester monomer and an aromatic vinyl monomer having at least one type of benzene ring skeleton are copolymerized, and then the benzene ring is hydrogenated, or a method in which a (meth)acrylic acid ester monomer and an aliphatic vinyl monomer having at least one type of cyclohexyl ring skeleton are copolymerized, with the former being particularly preferred.

[0084] The (meth)acrylic acid ester monomer is not particularly limited, but examples thereof include methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, cyclohexyl (meth)acrylate, isobornyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, 2-hydroxy-2-methylpropyl (meth)acrylate, 2-methoxyethyl (meth)acrylate, 2-ethoxyethyl (meth)acrylate, 2-phenoxyethyl (meth)acrylate, benzyl (meth)acrylate, and phenyl (meth)acrylate.

[0086] Examples of the aliphatic vinyl monomer include vinylcyclohexane, isopropenylcyclohexane, 1-propenyl-2-methylcyclohexane, etc. Among these, vinylcyclohexane and isopropenylcyclohexane are preferred.

[0087] The polymerization of the (meth)acrylic acid ester monomer and the aromatic vinyl monomer can be carried out by known methods, such as bulk polymerization, solution polymerization, suspension polymerization, and emulsion polymerization. In the solution polymerization method, a monomer composition containing a solvent, monomers, a chain transfer agent, and a polymerization initiator is continuously supplied to a complete mixing vessel, and continuous polymerization is carried out at 100 to 180°C.

Examples of suitable solvents include hydrocarbon solvents such as cyclohexane and methylcyclohexane; ester solvents such as ethyl acetate and methyl isobutyrate; ketone solvents such as acetone and methyl ethyl ketone; ether solvents such as tetrahydrofuran and dioxane; and alcohol solvents such as methanol and isopropanol.

[0090] The hydrogenation method is not particularly limited, and known methods can be used. For example, the hydrogenation can be carried out in a batch or continuous flow system at a hydrogen pressure of 3 to 30 MPa and a reaction temperature of 60 to 250°C. By setting the temperature to 60°C or higher, the reaction time does not become too long, and by setting the temperature to 250°C or lower, scission of molecular chains and hydrogenation of ester moieties are less likely to occur.

[0091] Examples of catalysts used in the hydrogenation reaction include solid catalysts in which a metal such as nickel, palladium, platinum, cobalt, ruthenium, or rhodium, or an oxide, salt, or complex compound of such a metal is supported on a porous carrier such as carbon, alumina, silica, silica-alumina, or diatomaceous earth.

[0092] In the hydrogenation reaction, it is preferable that 70% or more of the aromatic rings in the aromatic vinyl monomer are hydrogenated. That is, it is preferable that the proportion of unhydrogenated aromatic ring sites in the aromatic vinyl structural unit is less than 30%. If the proportion of unhydrogenated aromatic ring sites exceeds 30%, transparency may decrease when used as an acrylic resin. The proportion of unhydrogenated aromatic ring sites is more preferably less than 10%, even more preferably less than 5%, and particularly preferably less than 1%. In consideration of productivity, it is not necessarily necessary to make it 0%.

[0093] The polymerization of the (meth)acrylic acid ester monomer and the aliphatic vinyl monomer can be carried out by a known method, for example, the method described in JP-A Nos. 63-3011 and 63-170475.

[0094] The glass transition temperature of the acrylic resin is preferably in the range of 110 to 160°C, more preferably 115 to 150°C.

[0095] The acrylic resins may be used alone or in combination of two or more.

The above-mentioned range of polystyrene-equivalent weight average molecular weight (Mw) mainly relates to polycarbonate resins, polyester resins, and polyester carbonate resins. Meanwhile, the acrylic resin contained in the thermoplastic resin may have a polystyrene-equivalent weight average molecular weight (Mw) within the above-mentioned range, but is preferably 100,000 to 200,000, more preferably 110,000 to 170,000.

[0097] [2. Properties of Thermoplastic Resin Composition] The thermoplastic resin composition of the present invention containing a compounding agent can maintain a high level of transmittance (%) compared to a thermoplastic resin composition not containing a compounding agent.

[0098] For example, the thermoplastic resin composition has a transmittance (%) value at wavelengths of 370 nm to 400 nm according to JIS K7105 that is 1.0% or more higher, preferably 2.0% or more higher, than a target resin composition having the same composition but without any additives. That is, when the transmittance (%) value at wavelengths of 370 nm to 400 nm according to JIS K7105 of the target resin composition not containing additives is compared with the transmittance (%) value at wavelengths of 370 nm to 400 nm according to JIS K7105 of the thermoplastic resin composition of the present invention, the transmittance value of the thermoplastic resin composition is higher, with the difference between these values ​​being 1.0% or more, preferably 2.0% or more. More preferably, the transmittance value of the thermoplastic resin composition is 3.0% or more higher, more preferably 4.0% or more higher, than the transmittance value of the target resin composition. The difference in transmittance (%) is also observed, for example, in the wavelength range of 380 nm to 400 nm in accordance with JIS K7105.

[0099] Furthermore, for example, the thermoplastic resin composition has a transmittance (%) at wavelengths of 370 nm to 400 nm as measured in accordance with JIS K7105 that is 1.1 times or more higher than that of a resin composition for a target application having the same composition but without the addition of additives. That is, when the transmittance (%) at wavelengths of 370 nm to 400 nm as measured in accordance with JIS K7105 for a resin composition for a target application that does not contain additives is compared with the transmittance (%) at wavelengths of 370 nm to 400 nm as measured in accordance with JIS K7105 for the thermoplastic resin composition of the present invention, the transmittance (%) of the thermoplastic resin composition is higher than that of the resin composition for a target application and is 1.1 times or more higher. Preferably, the transmittance of the thermoplastic resin composition is 1.3 times or more, and more preferably 1.5 times or more, of the resin composition for a target application.

[0100] When additives such as a mold release agent or an antioxidant are added to the thermoplastic resin composition of the present invention, the transmittance value of the resulting thermoplastic resin composition tends to decrease. However, when the thermoplastic resin composition contains the above-mentioned compounding agents, the decrease in the transmittance value can be prevented or suppressed.

[0101] Furthermore, a thermoplastic resin composition according to a certain embodiment has a lower YI value than a target resin composition having the same composition as the thermoplastic resin composition except for the absence of the additive. Specifically, the YI value of a thermoplastic resin composition containing the additive, for example, the YI value according to JIS K 7105, can be 0.20 or more lower than the YI value of a thermoplastic resin composition having the same components but without the additive. The difference between these YI values ​​is, for example, 0.50 or more, 0.80 or more, 0.90 or more, 1.0 or more, or even 1.1 or more. The YI value according to JIS K 7105 of a thermoplastic resin composition containing the additive is preferably 1.2 or more lower than the YI value of a thermoplastic resin composition having the same components but without the additive. The difference between these YI values ​​is more preferably 1.5 or more, 1.80 or more, or 2.0 or more, and even more preferably 2.2 or more, 2.5 or more, 2.7 or more, or 3.0 or more. In addition, the YI value of a thermoplastic resin composition containing a compounding agent represented by the above-mentioned general formula (1), for example, in accordance with JIS K 7105, can be calculated by the ratio of the monomer corresponding to the compounding agent represented by the above-mentioned general formula (1) (for example, R １ ~R ５ The YI value of the thermoplastic resin composition is preferably smaller by 0.2 or more than the YI value of a thermoplastic resin composition containing the same amount of a compounding agent (a compound common to general formula (1-1) but not containing the cyclic structure of general formula (1-1)). The difference in these YI values ​​is more preferably 0.3 or more, 0.4 or more, or 0.5 or more, and even more preferably 0.6 or more, 0.7 or more, 0.8 or more, 0.9 or more, or 1.0 or more.

[0102] As described above, the thermoplastic resin composition of the present invention, which maintains high transmittance and enables improved hue, as indicated by a low YI value, is suitable for applications such as optical materials. The thermoplastic resin composition of the present invention is particularly suitable for use as an optical material. Furthermore, the thermoplastic resin composition of the present invention has high heat resistance and transparency, and is expected to have a volatile component reduction effect. In particular, the polyester resin composition of the thermoplastic resin composition of the present invention has been confirmed to have a volatile component reduction effect at high temperatures, as described in detail below, and can suppress odors generated during heating. Therefore, the thermoplastic resin composition of the present invention, primarily the polyester resin composition, is also useful as a plastic for food container packaging, for example. For example, a certain embodiment of the thermoplastic resin composition has the same or better volatile component reduction effect, as described in detail below, as compared to a target resin composition having the same composition as the thermoplastic resin composition but without the additives. In other words, the thermoplastic resin composition can suppress the amount of volatile components generated under specific conditions, such as heating at 250°C for 5 minutes, as described below. Specific examples of volatile components include formaldehyde, acetaldehyde, acetone, 2,3-butanedione, acetic acid, and formic acid.

[0103] [3. Method for Producing Thermoplastic Resin Composition] The method for producing a thermoplastic resin composition of the present invention includes a step of adding the compounding agent to a thermoplastic resin. By adding the compounding agent to a thermoplastic resin, the transmittance of the thermoplastic resin, particularly the transmittance at low wavelengths, can be maintained at a good level compared to a thermoplastic resin to which the compounding agent is not added.

[0104] [4. Method for Improving Transmittance of Thermoplastic Resin Composition] The method for improving the transmittance of a thermoplastic resin composition of the present invention includes a step of adding the above-mentioned compounding agent to a thermoplastic resin. By adding the compounding agent to a thermoplastic resin, the transmittance of the thermoplastic resin, particularly the transmittance value at low wavelengths, can be improved. In particular, a thermoplastic resin composition to which a compounding agent has been further added can have an improved transmittance value compared to a thermoplastic resin to which an additive different from the compounding agent has been added.

[0105] [5. Method for Improving the Hue of a Thermoplastic Resin Composition] The method for improving the hue of a thermoplastic resin composition of the present invention includes adding the above-described compounding agent to a thermoplastic resin. By adding the compounding agent to a thermoplastic resin, the hue of the thermoplastic resin can be improved or improved, thereby increasing the transparency of the thermoplastic resin. As described above, the YI value of a thermoplastic resin composition containing a compounding agent is lower by, for example, 0.2 or more in accordance with JIS K 7105 than the YI value of a thermoplastic resin composition containing the same components but without the compounding agent. Therefore, thermoplastic resin compositions containing a compounding agent tend to have less yellowish coloration, which is usually observed, and have excellent hue. In other words, adding a compounding agent to a thermoplastic resin composition can reduce the YI value of the thermoplastic resin composition, and the difference in YI value between the presence and absence of the compounding agent can be, for example, 0.20 or more, 0.50 or more, 0.80 or more, 0.90 or more, 1.0 or more, or even 1.1 or more, as described above. When the compounding agent described above is added to a thermoplastic resin composition, the YI value according to, for example, JIS K 7105 is preferably 1.2 or more smaller than the YI value of a thermoplastic resin composition having the same components but not containing the compounding agent. The difference between these YI values ​​is more preferably 1.5 or more, 1.80 or more, or 2.0 or more, and even more preferably 2.2 or more, 2.5 or more, 2.7 or more, or 3.0 or more. Note that by adding the compounding agent represented by the above general formula (1) to a thermoplastic resin composition, the YI value according to, for example, JIS K 7105 can be reduced by the amount of the monomer corresponding to the compounding agent represented by the above general formula (1) (for example, R in general formula (1)). １ ~R ５ The YI value of the thermoplastic resin composition can be reduced by preferably 0.2 or more compared to the YI value of a thermoplastic resin composition containing the same amount of a compound (a compound common to general formula (1-1) but not containing the cyclic structure of general formula (1-1)) as a compounding agent. The difference in YI value is more preferably 0.3 or more, 0.4 or more, or 0.5 or more, and even more preferably 0.6 or more, 0.7 or more, 0.8 or more, 0.9 or more, or 1.0 or more.

[0106] [6. Method for Reducing Haze of Thermoplastic Resin Composition] The step of adding the compounding agent to a thermoplastic resin can also reduce the haze value of the thermoplastic resin, for example, the haze value in accordance with JIS K-7361 and JIS K-7136. That is, the haze value of a thermoplastic resin composition tends to be smaller than the haze value of a target resin composition having the same composition as the thermoplastic resin composition except that it does not contain the compounding agent, and the difference between these haze values ​​is, for example, 0.01 or more, 0.02 or more, 0.03 or more, 0.04 or more, or 0.05 or more.

[0107] [7. Molded Articles] The thermoplastic resin composition of the present invention can be used for extrusion molding, blow molding, injection molding, and the like. Examples of molded articles that can be obtained include extrusion molded articles, hollow molded articles, precision parts, and thin injection molded articles. The thermoplastic resin composition of the present invention can maintain a good transmittance value. Therefore, the thermoplastic resin composition of the present invention is particularly suitable as an optical material, etc. Molded articles produced using such thermoplastic resin compositions include optical lenses, optical films, transparent conductive substrates used in liquid crystal displays, organic EL displays, solar cells, etc., optical disks, liquid crystal panels, optical cards, sheets, films such as retardation films, optical fibers, connectors, vapor-deposited plastic reflectors, displays, touch panels, etc. These optical molded articles have high transmittance even when they contain additives added for various applications. Specific examples of molded articles using the thermoplastic resin of the present invention as optical materials and related applications include optical media such as compact discs, digital video discs, minidiscs, and magneto-optical discs; optical communication media such as optical fiber; optical components such as car headlamp lenses and camera lenses; siren light covers, lighting lamp covers, window glass replacements for trains and automobiles; window glass replacements for homes; lighting components such as sunroofs and greenhouse roofs; lenses and housings for goggles, sunglasses, and eyeglasses; housings for office equipment such as copy machines, facsimiles, and personal computers; housings for home appliances such as televisions and microwave ovens; and electronic component applications such as connectors and IC trays. Furthermore, examples of molded articles obtained from the thermoplastic resin composition of the present invention include, but are not limited to, the following, which require high heat resistance and high transparency. These include automobile components such as headlamp lenses, meter panels, sunroofs, and also glass window replacements and exterior panel parts; various films for liquid crystal displays, light guide plates, optical disc substrates, and housings for electronic devices such as smartphones; and building materials such as transparent sheets.Even in the case of molded articles that do not require the excellent transparency of the thermoplastic resin composition of the present invention, the high transparency of the raw material resin composition has the advantage that it is easier to control the degree of coloration with colorants such as pigments and dyes.

[0108] Furthermore, if necessary, a coating layer such as an antireflection layer or a hard coat layer may be provided on the surface of the optical molded body. The antireflection layer may be a single layer or a multilayer, and may be made of either an organic or inorganic material, but is preferably made of an inorganic material. Specific examples include oxides or fluorides such as silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, cerium oxide, magnesium oxide, and magnesium fluoride.

[0109] [7-1. Optical Lenses] Optical lenses produced using the thermoplastic resin composition of the present invention have excellent transmittance characteristics. Furthermore, optical lenses produced using the polycarbonate resin of the present invention have a high refractive index, a low Abbe number, and high humidity and heat resistance. Therefore, they are extremely useful in fields where expensive high-refractive-index glass lenses have traditionally been used, such as telescopes, binoculars, and television projectors. If necessary, they are preferably used in the form of aspherical lenses. Aspherical lenses can substantially eliminate spherical aberration with a single lens, eliminating the need to eliminate spherical aberration by combining multiple spherical lenses, thereby enabling weight reduction and reduced production costs. Therefore, aspherical lenses are particularly useful as camera lenses. Optical lenses can be molded by any method, such as injection molding, compression molding, or injection-compression molding. The present invention makes it possible to more easily obtain high-refractive-index, low-birefringence aspherical lenses, which are technically difficult to process using glass lenses. To prevent foreign matter from getting into the optical lens as much as possible, the molding environment must naturally be a low-dust environment, preferably class 6 or less, more preferably class 5 or less.

[0110] The optical lens produced using the thermoplastic resin composition of the present invention can be obtained by injection molding the polycarbonate copolymer of the present invention into a lens shape using an injection molding machine or an injection compression molding machine. The molding conditions for injection molding are not particularly limited, but the molding temperature is preferably 180 to 280°C. The injection pressure is preferably 50 to 1700 kg / cm. ２In order to minimize the incorporation of foreign matter into the optical lens, the molding environment must naturally be a low-dust environment, preferably Class 1000 or less, more preferably Class 100 or less. Optical lenses containing the thermoplastic resin composition of the present invention are preferably used in the form of aspherical lenses, if necessary. Aspherical lenses can achieve essentially zero spherical aberration with a single lens, eliminating the need to eliminate spherical aberration by combining multiple spherical lenses, thereby enabling weight reduction and reduced production costs. Therefore, aspherical lenses are particularly useful as camera lenses. The astigmatism of the aspherical lens is preferably 0 to 15 mλ, more preferably 0 to 10 mλ. The thickness of the optical lens manufactured using the thermoplastic resin composition of the present invention can be set within a wide range depending on the application and is not particularly limited, but is preferably 0.01 to 30 mm, more preferably 0.1 to 15 mm. If necessary, a coating layer such as an antireflection layer or a hard coating layer may be provided on the surface of the optical lens of the present invention. The antireflection layer may be a single layer or a multilayer, and may be organic or inorganic, but is preferably inorganic. Specific examples include oxides or fluorides such as silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, cerium oxide, magnesium oxide, and magnesium fluoride. Among these, silicon oxide and zirconium oxide are more preferred, and a combination of silicon oxide and zirconium oxide is even more preferred. Regarding the antireflection layer, there are no particular limitations on the single-layer / multilayer combination, or the combination of their components and thicknesses. However, a two-layer or three-layer configuration is preferred, and a three-layer configuration is particularly preferred. The antireflection layer as a whole is preferably formed to a thickness that is 0.00017 to 3.3% of the thickness of the optical lens, specifically 0.05 to 3 μm, and particularly preferably 1 to 2 μm.

[0111] [7-2. Optical Film] The optical film produced using the thermoplastic resin composition of the present invention has excellent transparency and heat resistance, and is therefore suitable for use as a film for liquid crystal substrates, optical memory cards, etc. To prevent foreign matter from being mixed into the optical film as much as possible, the molding environment must naturally be a low-dust environment, preferably class 6 or less, and more preferably class 5 or less.
