Description

  The present invention is an optical three-dimensional modeling active energy that gives a three-dimensional modeled article that has a low viscosity in an uncured state, a high curing rate by light irradiation, excellent molding accuracy, and excellent mechanical properties such as strength and heat resistance. The present invention relates to a linear polymerizable resin composition.

In addition to various characteristics such as fast polymerization rate, good workability due to the absence of solvent, energy saving of extremely low energy requirements, active energy ray polymerization technology has recently reduced environmental pollution due to environmental pollution problems. Therefore, the field of use is expanding in the fields of building materials, packaging materials, printing materials, display materials, electrical and electronic component materials, optical devices, displays, and the like.
These contain only a resin that can be polymerized with active energy rays and a monomer having an α, β-unsaturated double bond group, and since the monomer also functions as a solvent, a coating film or a molded product is formed. This is because sometimes the solvent does not volatilize. And as this resin having active energy ray polymerizability, it has an α, β-unsaturated double bond group at the molecular terminal of a low molecular weight polyester resin, polyurethane resin, polyepoxy resin, polyacrylic resin, etc. Oligomers and monomers having an α, β-unsaturated double bond group are used.

In recent years, as a method for producing resin molded products, an ultraviolet laser, which is a kind of active energy ray, is obtained from a liquid photocurable resin composition based on three-dimensional shape data designed by a three-dimensional design system (three-dimensional CAD) on a computer. An optical three-dimensional modeling method (optical modeling method) for producing a molded product by selectively curing with light is used.
Compared to conventional cutting, this stereolithography method can deal with complex shapes that are difficult to cut, is a fully automated process, is easy to handle, has a short manufacturing time, and is advantageous in terms of cost. In addition to the production of resin products, it has come to be widely used in the manufacture of prototype models and medical models for design studies, performance tests, advertisements, and the like.
As a representative example of this three-dimensional modeling method, light, for example, a kind of active energy ray, is obtained so that a polymerization cured layer having a desired pattern is obtained on the liquid surface of the liquid photocurable resin composition placed in a container. Is selectively irradiated with ultraviolet laser light to obtain a polymerized cured layer, and then a liquid photocurable resin composition is supplied on the cured layer in a layered manner, and then the light is selectively irradiated as described above. Irradiation forms a cured polymer layer that is continuous with the cured layer. This is a method of finally obtaining a desired three-dimensional modeled object by repeating this lamination operation. This three-dimensional modeling method is attracting attention because even if the shape of a model to be manufactured is complicated, the target model can be easily obtained in a short time.

As the optical three-dimensional modeling method, for example, as disclosed in Patent Document 1, the energy supply necessary for the liquid photocurable resin composition is selectively performed to form a three-dimensional modeled object having a desired shape. Is the method. Such a method or an improved technique thereof is disclosed in Patent Documents 2 and 3.

As a photocurable resin composition used for the above-mentioned optical modeling, from the viewpoint of efficient optical modeling, it is possible to quickly form a smooth liquid surface with low viscosity, transparency and good photocuring. It is required to have sex. In addition, there is a problem that the cured product may be deformed over time (warping, shrinkage, lifting of the overhang portion, etc.) due to residual distortion caused by shrinkage (curing shrinkage) during polymerization curing by light. Small deformation over time is required. Furthermore, depending on the application, the polymerized cured product is required to have mechanical strength such as toughness, heat resistance, moisture resistance, and water resistance.

Conventionally, as such a photocurable resin composition, from the viewpoint of transparency, photocurability and the like, radically polymerizable compounds such as urethane (meth) acrylate, epoxy (meth) acrylate, and photosensitive polyimide (for example, patents) Documents 4 and 5), resin compositions containing cationically polymerizable compounds such as epoxy compounds and vinyl ether compounds (for example, Patent Document 6) are used. However, with the recent miniaturization and complication of target products, the demand for dimensional accuracy has become increasingly severe, and the temporal deformation characteristics of the resin composition cannot satisfy the demand.
Furthermore, Patent Document 7 discloses a photocurable liquid composition containing fine hollow spheres whose absolute value of the difference in refractive index from an ethylenically unsaturated monomer or photoinitiator is not 0. It is described that the transparency of the ionic liquid composition is reduced. Furthermore, Patent Document 8 discloses a radiation curable resin composition containing a color former, and a three-dimensional article produced from the radiation curable resin composition exhibits different colors before and after curing. Is described.
However, the cured resin obtained by curing the above resin composition has not yet satisfied all the requirements for toughness, water resistance, physical property stability and suppression of deformation over time.

When using a polar resin for the coloring material (H) of this invention, it is preferable that a polar resin is 0.1 to 80 weight% in the coloring material (H) whole quantity. If the concentration is less than 0.1% by weight, the dispersion and stabilization of the dye or pigment cannot be expected. On the other hand, if the amount exceeds 80% by weight, the modeling performance is remarkably deteriorated, or even if the modeling is completed, the durability of the three-dimensional modeled object such as water resistance and heat-and-moisture resistance tends to decrease.

<Additive (Q)>
If the resin composition of the present invention is within the range not impairing the effects of the present invention, various additives (Q) can be appropriately blended in addition to the above-described components. For example, blending organic or inorganic fillers from the viewpoints of polymerization cure shrinkage reduction, thermal expansion coefficient reduction, dimensional stability improvement, elastic modulus improvement, viscosity adjustment, thermal conductivity improvement, strength improvement, toughness improvement, coloring improvement, etc. it can.

<Properties of Active Energy Ray Polymerizable Resin Composition for Optical Stereolithography>
Next, the properties of the active energy ray polymerizable resin composition for optical three-dimensional modeling will be described.
The resin composition of the present invention comprises the compound (I), the compound (A), the compound (B), and the compound (J) as essential components, and further, if necessary, the compound (C) and the compound (D). , Photopolymerization initiator (E), silane compound (F), antioxidant (G), colorant (H) and other various additives (Q) can be mixed and then mixed to be manufactured uniformly. it can.
When stirring and mixing, it may be prepared by stirring and mixing using a general-purpose device such as a uniaxial or multiaxial extruder, a kneader, or a dissolver equipped with a decompression device. Usually, the temperature at the time of stirring and mixing is preferably set to 10 to 60 ° C. If the set temperature at the time of preparation is less than 10 ° C, the viscosity may be too high to make uniform stirring / mixing work difficult. Conversely, if the temperature at the time of preparation exceeds 60 ° C, a curing reaction due to heat occurs. In some cases, a normal fat composition may not be obtained.

The resin composition of the present invention can be used in any form of liquid, paste, and film.
In addition, although it is preferable that the resin composition in this invention does not contain an organic solvent substantially, it is also possible to contain an organic solvent. For example, by further adding an organic solvent such as methanol, ethanol, isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, methyl acetate, ethyl acetate, butyl acetate, cyclohexane, toluene, xylene and other hydrocarbon solvents, water, The viscosity of the resin composition for optical three-dimensional modeling can be adjusted, or the viscosity can be lowered by heating the resin composition for optical three-dimensional modeling.

It is important that the resin composition for optical three-dimensional modeling in the present invention has a viscosity at 25 ° C. of 1 to 2000 mPa · s, preferably 10 to 1500 mPa · s, and 20 to 1000 mPa · s. More preferred. When the viscosity is higher than 2000 mPa · s, when the resin cured product is used, three-dimensional modeling cannot be performed and the hardness deteriorates. On the other hand, if the viscosity is lower than 1 mPa · s, it becomes difficult to control the dimensional stability of the cured resin resin.
Since the viscosity of the resin composition is almost determined by the viscosity of the compound (A) and the compound (B), the viscosity of the resin composition is controlled by managing these viscosities in the range of 1 to 100,000 mPa · s. Can also be managed.

<Modeling process of an active energy ray polymerizable resin composition for optical three-dimensional modeling>
Next, a modeling process (optical three-dimensional modeling method) of the cured resin and the active energy ray polymerizable resin composition for optical three-dimensional modeling will be described.
The resin composition of the present invention is suitably used as a photocurable liquid resin material in an optical three-dimensional modeling method (hereinafter also referred to as an optical modeling method). That is, a resin cured product having a desired three-dimensional shape is produced by an optical modeling method that selectively irradiates active energy rays such as ultraviolet rays to the resin composition of the present invention to supply energy necessary for polymerization and curing. be able to.

The resin composition of the present invention is suitably used as a curable liquid material in an optical three-dimensional modeling method. That is, by selectively irradiating a specific portion of the resin composition with light such as visible light, ultraviolet light, infrared light, etc., and supplying active energy necessary for polymerization and curing, a three-dimensional shaped object with a desired shape is obtained. Can be obtained.
The active energy ray irradiation light source mainly consists of light in the wavelength range of 150 to 550 nm. Low pressure mercury lamp, medium pressure mercury lamp, high pressure mercury lamp, ultra high pressure mercury lamp, chemical lamp, black light lamp, microwave excitation mercury lamp, LED In addition to lamps, xenon lamps, metal halide lamps and the like, semiconductor laser beams, electron beams, and the like can also be used as active energy rays for exposure. In view of cost, directivity, and convergence, an ultraviolet laser beam is preferable.
The irradiation intensity of the active energy ray is preferably ¹ to 500 mW / cm ² . If the light irradiation intensity is less than 1 mW / cm ² , a long time is required for curing, and if it exceeds 500 mW / cm ² , the uncured resin composition may be deteriorated due to heat radiated from the lamp. This is not preferable. The integrated dose expressed as a product of irradiation intensity and irradiation time is preferably ¹ to 5,000 mJ / cm ² . When the integrated irradiation amount is less than 1 mJ / cm ² , it takes a long time for polymerization and curing, and when it is larger than 5,000 mJ / cm ² , the irradiation time becomes very long and the productivity is inferior.

A method for selectively irradiating light, which is an active energy ray for polymerization and curing, to a specific portion of the resin composition is not particularly limited, and can be performed by various methods. For example, a method of irradiating focused light or the like obtained by using a laser beam, a lens, a mirror, or the like to a specific portion, a method of irradiating non-focused light through a fixed pattern mask, or the like can be employed. However, when fine processing or processing accuracy is required, it is desirable to minimize the size of the focused light. In such a case, it is preferable to use laser light. Furthermore, the specific part of the resin composition that is irradiated with light may be the liquid surface of the resin composition placed in the container, the surface of the resin composition in contact with the side wall or the bottom wall of the container, or the liquid. In order to irradiate the liquid surface of the resin composition or the contact surface with the container wall, the light may be irradiated directly from the outside or through a transparent vessel wall. Irradiation may be performed using a light guide such as the above.

Further, in the above-described optical three-dimensional modeling method, usually, after a specific portion of the resin composition is polymerized and cured, the irradiated position is moved continuously or stepwise from an already cured portion to an uncured portion. Thus, the cured portion can be grown into a desired three-dimensional shape. This irradiation position can be moved by various methods, for example, moving at least one of a light source, a container containing the resin composition, or a cured portion of the resin composition, or uncured in the container. The resin composition (liquid curable material) can be added.

<3D objects>
Next, a three-dimensional molded item will be described.
As a typical method for obtaining a three-dimensional structure using the resin composition of the present invention, light is used so that a cured layer having a desired pattern is obtained in the liquid resin composition for optical three-dimensional structure of the present invention. To form a cured layer, and then irradiate light to the uncured composition layer adjacent to the cured layer in the same manner to form a new cured layer continuous with the previously formed cured layer. By repeating this lamination operation, a method for finally obtaining a three-dimensional shaped object can be mentioned. As a more specific embodiment of this method, the following method can be exemplified.

The formed three-dimensional model is taken out from the container used for the reaction, and after removing unreacted compounds remaining on the surface of the model, it is washed as necessary. Examples of the cleaning agent include organic solvents represented by alcohols such as isopropyl alcohol and ethyl alcohol, organic solvents represented by acetone, ethyl acetate, methyl ethyl ketone, and the like, aliphatic compounds represented by terpenes and glycol ether esters. A low-viscosity liquid resin having an organic solvent, thermosetting property or photo-curing property (meaning polymerization curing property by light which is an active energy ray) can be used. When it is desired to impart transparency to the three-dimensional structure, it is desirable to use the thermosetting or photocurable liquid resin as a cleaning agent. In this case, depending on the type of resin used for cleaning, it is necessary to dry (also referred to as post-cure) with heat or light after cleaning. Note that post-curing has the effect of curing not only the resin on the surface but also the unreacted resin composition that may remain inside the three-dimensional structure, so it is washed with an organic solvent. It is preferable to carry out also in this case.

The resin cured product of the optical three-dimensional modeling active energy ray-polymerizable resin composition of the present invention includes various three-dimensional modeling products for electronic products that require complicated and fine processing; It can be preferably used as a three-dimensional model such as a model for advertisement or exhibition; a prototype for development such as performance test or production aptitude confirmation; or a medical model for simulation of surgery.
