Description

Method for producing color polymer film for vacuum molding {Method For Producing Highly thermoformable colored polymer film}

The present invention improves extrusion and vacuum forming, and has a uniform color even after vacuum forming, and is capable of forming a polymer film or sheet for vacuum forming (hereinafter referred to as a film) capable of forming an antistatic layer containing a conductive polymer as an active ingredient on its surface. The present invention relates to a manufacturing technique and an antistatic packaging for transporting electronic components manufactured therefrom.

Recently, in the case of trays for transporting and processing precision electronic components, the use of colored trays is gradually increasing for ease of inspection and use of packaged products during the process. In general, a colored tray may be easily prepared by mixing a predetermined amount of inorganic particles to give a color to the base polymer resin for the tray and extruding them to produce a polymeric film having a color, and vacuum forming the same. However, when the tray is manufactured by the vacuum molding method, an elongation of 1,000% or more may be required. Unlike the injection molding method and the blow molding method, there are some areas in which the polymer film is extended and some parts are not stretched by vacuum molding. In the portion where the polymer film is stretched a lot, the color becomes thinner than other portions, which causes a problem that the color of the tray is not uniform.

Thus, the problem that the color is not uniform after vacuum molding can be solved to some extent by greatly increasing the content of the component representing the color. However, since the color components are mainly inorganic particles, a large increase in the content of the color components in order to have a uniform color in the vacuum molded article means that the content of the inorganic particles increases greatly, and thus the inorganic content in the polymer resin. Increasing this will eventually cause a problem that the moldability of the polymer film is greatly reduced. In particular, in the case of the amorphous polyester film which is most used for vacuum molding, there is a problem that the molding is not possible if the inorganic content is greatly increased. For example, if carbon black is mixed to produce a black light shielding tray, increasing the carbon black content to make the tray uniformly black overall yields a uniform color but does not form. If the content of carbon black is reduced, molding occurs, but a problem of not obtaining a uniform color occurs.

In order to solve these problems in recent years, the light shielding property is based on the light scattering property of the components mixed in the polymer resin, and it is possible to improve the light scattering properties by using a mixture of components that exhibit light scattering and uniform color while vacuuming. Vacuum molding polymer film and a vacuum forming tray manufacturing technology manufactured therefrom have been devised and applied to polyester film or the like. (See Korea Patent Application No. 10-2004-0108266, Republic of Korea Patent Application No. 10-2005-0012507)

Although the technique can be successfully applied in terms of light shielding and uniform color, the dispersibility of these inorganic components always remains a problem. That is, when a large amount of inorganic fillers are melt-mixed with the polymer resin, the inorganic fillers are poor in dispersibility, so that the inorganic fillers are agglomerated in the polymer resin, which means that more inorganic fillers than necessary are used. In addition, there is a problem that the physical properties of the polymer film is likely to be lowered by being present in a form in which a large amount of inorganic fillers are aggregated. These problems can be improved to some extent through existing methods such as adding a certain amount of an interfacial binder when mixing the inorganic filler with the base polymer resin, but as described above, it is possible to simply melt-mix the inorganic filler with the polymer resin. Does not fundamentally solve the problem of evenly dispersing a large amount of inorganic filler in the polymer resin.

In order to improve the problem, a method of mixing a high-density inorganic resin to give a color to use a high molecular resin first to make a so-called masterbatch first, and then mixed with a pure resin is extruded. However, when the resin to be used has a high inorganic particle content such as amorphous polyester, when the physical properties are greatly reduced, it is not possible to mix a large amount of inorganic particles in the preparation of the master batch. Therefore, it is necessary to prepare a master batch having a relatively low content of inorganic particles and to add the master batch at a high content when mixing with a pure resin, which causes economic problems due to the use of a large amount of master batches.

Therefore, when the polymer film for vacuum molding is manufactured by the extrusion method by mixing the component which gives color with the polymer resin, the dispersibility of the inorganic particles exhibiting color is greatly improved, thereby achieving uniform color even at a low inorganic content. In addition, the invention of an economical polymer film capable of improving moldability during vacuum molding and forming an antistatic layer containing a conductive polymer as an active ingredient on the surface of the film and an antistatic packaging container for transporting electronic components manufactured therefrom is required. Do.

The present invention greatly improves the dispersion of the constituents that give color when producing a polymer film for vacuum molding by the extrusion method, thereby exhibiting uniform color even with a small content and having elongation necessary for vacuum molding, thereby improving moldability. An object of the present invention is to provide an economical vacuum-forming polymer film capable of forming an antistatic layer containing a conductive polymer as an active ingredient on its surface, and a packaging container for transporting electronic components manufactured therefrom.

In order to achieve the above object, the present invention,

Preparing a base polymer;

Preparing a colored liquid composition by mixing a low molecular weight compound having good compatibility with the base polymer in a content ratio of 95: 5-5: 95 with a color component; And

Extruding the colored liquid composition into a polymer film having a thickness of 0.1-5.0 mm by mixing the base polymer resin so that the content of the color component is 0.001-10 parts by weight with respect to the base polymer resin;

It provides a method for manufacturing a polymer film for vacuum and compression molding, including the antistatic layer is formed.

In the present invention, the inorganic particles exhibiting color are mixed with a liquid low molecular weight compound having good compatibility with the base polymer to form a colored liquid composition, and then mixed with the base polymer and extruded to form a polymer for vacuum molding having a thickness of 0.1-5.0 mm. The technique of making the film was used.

The technique of the present invention is a method of selecting a liquid low molecular weight compound, a method for producing a colored liquid composition by mixing the liquid low molecular weight compound of the color-containing inorganic components, and extruded by mixing the colored liquid composition with the base polymer resin It consists of three main challenges: the technique.

First, the liquid low molecular weight compound has good compatibility with the base polymer, and a different type of compound should be selected according to the type of the base polymer. The liquid low molecular weight compound is a compound containing any one or more functional groups selected from ester group, ether group, urethane group, hydroxyl group, carboxyl group, thio group, styrene group, acryl group, acrylonitrile group, imide group and amide group A compound having a molecular weight of 100-5,000 grams / mole, wherein at least one of the functional groups is linked with a methylene group or a ring structured component, and is a compound modified from these (eg, polyoxyethylene nonyl Phenyl ether, polyoxyethylene octyl phenyl ether, polyoxyethylene stearyl amine, sorbitan monooleate, sorbitan trioleate, polyethylene glycol ester monolaurate, polyethylene glycol ester dilaurate).

The liquid low molecular weight compounds may be used without any problem, but in particular, when compatibility with the base polymer is very important, the low molecular weight is reduced by pyrolyzing the base polymer to make a liquid polymer having the same components as the base polymer resin and having a small molecular weight. When used in place of the liquid low molecular weight compound, it is effective to obtain the most sure compatibility with the base polymer. The method of obtaining a low molecular weight compound while maintaining the base polymer component by the pyrolysis method is a method using the property that the molecular weight of the polymer resin is reduced to a liquid phase. It is possible to obtain a low molecular weight compound having only a base polymer component.

Colored liquid composition may be prepared by mixing the low-molecular weight compound and the color-representing component in a certain container at a content ratio of (95: 5) / (5:95) and then stirring and mixing. Courage is more effective. In addition, the colored liquid composition may be prepared by roll milling in a container equipped with a roll mill, and the silane system may be used to further increase the dispersibility of particles to give color when preparing the colored liquid composition through the above methods. The use of an interfacial binder such as titanium, or a dispersant such as fatty acid stearic acid or fatty acid stearate may be used alone or in a mixture of 0.01 to 5 parts by weight relative to the content of the color component to obtain a better mixing effect.

When the colored liquid composition is mixed with the base polymer, the content of particles exhibiting color may be controlled in a range of 0.001-10 parts by weight relative to the base polymer. If the content of the color particles is less than 0.001 parts by weight, the content of the color-forming components is so low that it appears as if they are not mixed, and the effect of color adjustment is insignificant. This disadvantage is disadvantageous because of too high extrudability.

The colored liquid composition prepared by the above technique can be produced by mixing and extruding a polymer film having a color by mixing with a base polymer resin, in which case the following two methods can be used. First, there is a method of mixing a predetermined amount of liquid composition with the base polymer resin, so-called dry blending, and then injecting the same by injecting the base polymer resin into the extruder through the extruder hopper. Then, there is a method of extruding by directly injecting a predetermined amount of the liquid composition into the extruder through a separate inlet. Both of these methods can be used, but the first method has several problems, such as the appearance of the liquid composition on the dry blender wall during dry blending, which makes it difficult to control the exact content of the liquid composition. The second method of direct injection is more effective. There are several ways to directly inject the colored liquid composition into the extruder, depending on the type of the base polymer, and make a separate injection hole at the bottom of the hopper and then inject the liquid composition through the appropriate point in the middle of the extruder There is a method of injecting a liquid composition through the inlet to make it.

As described above, the most effective method of directly injecting the colored liquid composition into the extruder is as follows. In the extruder with a degassing device, a separate inlet is made at the bottom of the hopper, and the liquid composition is injected through the liquid composition so that the liquid composition is mixed with the base polymer resin while it comes to the vent part of the extruder, and the extra low molecular weight compound is removed through the vent part. By using this method, the low molecular weight compound can solve the problem of generating bubbles due to the high temperature inside the extruder. In addition, this method is more effective when producing a polymer film for vacuum molding, which is more likely to generate bubbles in the film due to the heat received during vacuum molding if a large amount of extra low molecular weight compound remains inside the film. This is because the problem that occurs during vacuum molding can be solved by completely removing extra low molecular weight components during the extrusion process.

When the colored liquid composition is mixed with the polymer resin and extruded in the same manner as described above to produce a single-layer polymer film, and then the tray is manufactured by vacuum forming, a tray having uniform color and improved extrudability and moldability is obtained. However, since the color components in the polymer film are also inorganic particles, the inorganic components are likely to come off the surface of the tray. Therefore, in order to eliminate this phenomenon, a polymer film having a three-layer structure must be manufactured by coextrusion. That is, in the production of a polymer film having a three-layer structure by the co-extrusion method, a colored liquid composition is mixed with the polymer resin in the middle layer and pure polymer without mixing the liquid composition in both surface layers is used for the three-layer structure. When the polymer film is prepared, even if the color imparting components are inorganic particles, it is possible to prepare a polymer film for vacuum molding, which fundamentally solves the problem of inorganic particles falling off from the surface of the tray after vacuum molding. It is possible to produce a tray for transporting electronic components having the inorganic particles do not come off from the surface.

In addition, in the extrusion process for producing a polymer film having a three-layer structure, when the low molecular weight compound of the present invention is mixed with a certain amount of the low molecular weight compound of the present invention to both surface layers of the film, these low molecular weight compounds lower the average molecular weight of the base polymer. It acts as a slag, which is effective because it improves the extrudability and formability of the polymer film. The content of the low molecular weight compound mixed in both surface layers may be controlled in the range of 0.001-5 parts by weight relative to the polymer. If the content of the compound is lower than 0.001 parts by weight, the effect of improving moldability is minimal, and the extrudability may be greater than 5 parts by weight. It is rather disadvantageous because it greatly reduces.

The polymer film having the color produced by the technique of the present invention has no problem in forming an antistatic layer containing the conductive polymer as an active ingredient on the surface of the polymer film. This is because the colored liquid composition used in admixture with the base polymer resin in the present invention does not significantly change the surface state of the polymer film. The main components of the colored liquid composition used in the present invention are inorganic particles showing color and low molecular weight compounds. The inorganic particles are not components affecting the coating property and adhesion of the antistatic liquid, and the low molecular weight compounds are compatible with the base polymer. If a good property is selectively used, there is no problem that the surface state of the polymer film is changed due to the so-called blooming phenomenon in which the low molecular weight component is released from the inside of the polymer film to the surface. Therefore, in this case, it does not affect the coating properties of the antistatic agent and the conventional antistatic agent using the conductive polymer as an active ingredient, but rather the low molecular weight compound, the average molecular weight of the polymer resin is lowered, so that the extrudability and vacuum molding of the polymer film There is an effect of improving the sex.

The polymer film produced using the technique of the present invention can be used for the purpose of manufacturing an antistatic film by coating various antistatic agents on the film surface. For example, an antistatic coating liquid containing a mixture of a conductive polymer and a binder as an active ingredient is applied to the surface of the polymer film of the present invention, dried, and cured to form an antistatic layer, and a polymer film using a liquid phase or gas phase polymerization method. It can be used to apply existing techniques such as a technique for forming an antistatic layer directly on the surface, a technique for forming an antistatic layer on the surface of a polymer film by mixing various conductive particles such as metal oxides or metal particles such as tin oxide or zinc oxide with a binder. have.

Preferably, the conductive polymer is to use polyaniline, polypyrrole, polythiophene and modified conductive polymer modified therefrom, and the antistatic layer containing the conductive polymer as an active ingredient may be a solution coating method or a liquid polymerization method and Direct polymerization such as vapor phase polymerization is used. In addition, the method of forming the antistatic layer by the solution coating method is used by a method such as spraying, electrodeposition coating, impregnation, etc. Also, the pencil hardness of the surface antistatic layer by UV curing when forming the antistatic layer by the solution coating method is 1H. It is more preferable if it is abnormal and does not wipe with an alcohol solvent.

When producing a polymer film having color using the technique of the present invention, as the base high molecular resin can be prepared using almost any polymer, it is applicable to a polymer having a light transmittance of 30% or more at 550 nm. For example, transparent polymers such as amorphous polyester (A-PET), polyester copolymer (PETG), polycarbonate, polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), and cyclic polyolefin (altone film) , Styrene-based polymers, olefin-based polymers, and translucent polymers such as polyimide, polyethersulfone, polyphenylene oxide, and polyetherimide as an active ingredient, or these components are in the form of blends or copolymers.
