 Hereinafter, the present invention will be described in more detail.

According to the present invention, it is surprising that a liquid crystal resin molded product having high strength, high conductivity, and stable conductivity can be obtained.

The present invention comprises at least two kinds of materials, namely, a liquid crystal resin and a conductive material.

First, a liquid crystal resin which is a main constituent material of the present invention will be described.

The liquid crystal resin of the present invention is a thermoplastic liquid crystal resin. That is, it is a liquid crystal resin having a mesogen group in the main chain.

Although there are various types of such liquid crystal resins, they are roughly classified into those made of aromatic polyester and those made of aromatic polyesteramide.

Various types of aromatic polyesters can be mentioned, and conventionally known ones can be applied, and there is no particular limitation.

Particularly preferred is a liquid crystal resin comprising the following structural units.

That is Here, X and Y each independently represent hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Structural units derived from a dicarboxylic acid include: Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Further, as structural units derived from hydroxycarboxylic acids: Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

In order to adjust the melt viscosity and the melting point of the liquid crystal resin of the present invention, it is also effective to introduce the following structural units. That is It is also effective to introduce a structural unit represented by the following general formula. That is (Where X represents O, CH ₂ , C (CH ₃ ) ₂ SO ₂ ), or a structural unit capable of relatively free rotation between aromatic rings, or (Where m and n are integers from 2 to 10) such as structural units derived from aliphatic diols and aliphatic dicarboxylic acids.

Particularly preferred liquid crystal polyarylate resins include those having the following structural formula. That is Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Here, Σni = 100 in each structural formula. Particularly preferred is that ni of each structural formula is 4 or more. In each formula, various substituents such as halogen may be added.

These compounds are particularly preferable because they have high melt moldability and high strength, and also have high melting points and glass transition points.

Next, there are various liquid crystal resins made of aromatic polyesteramides, and conventionally known ones can be widely applied and are not particularly limited.

The following are particularly preferred as typical ones. That is, the structural unit derived from aminophenol is represented by the following formula.

As the structural unit derived from an aromatic dicarboxylic acid, those represented by the following formula as well as those mentioned in the section of the liquid crystal polyarylate are particularly preferred.

Here, AR is at least one aromatic ring having an alkyl or alkoxy substituent having 4 or less carbon atoms and whose chain extension bond is coaxial or parallel and points to the opposite aromatic.

The liquid crystal polyesteramide has the following structural formula. That is Here, AR is at least one aromatic ring having an alkyl or alkoxy substituent having 4 or less carbon atoms, and whose chain extension bond is coaxial or parallel and faces in the opposite direction.

Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Here, X represents hydrogen, halogen, or an alkyl group having 4 or less carbon atoms.

Here, Σni = 100 in each structural formula. It is particularly preferable that ni of each structural formula is 15 or more. In each formula, various substituents such as halogen may be added. These materials have melt moldability and high strength similarly to the liquid crystal resin composed of polyarylate.

Although the liquid crystal resin of the present invention is thermoplastic in nature, it is particularly preferable that the liquid crystal resin is infusible when heat resistance is required.

In particular, when a high-strength liquid crystal resin molded product is required, it is preferable that the molecular weight of the liquid crystal resin is high to some extent. Particularly preferred is that the number average molecular weight of the liquid crystal resin is 1.
That's more than 30,000. Further, it is preferably 30,000 or more. In such a case, the strength of the liquid crystal resin molding becomes
40 kg / mm ² or more, and the elastic modulus is 2400 kg / mm ² or more, which is preferable because dimensional stability is enhanced and it can be widely used in many fields.

The form of the liquid crystal resin molded product of the present invention is not particularly limited, and fibers, ultrafine fibers, films, chips,
It includes all items such as plates, bars, square bars, and various molded products.

When the molded article of the present invention is required to have particularly light weight and whiteness, it is preferable that the molded article has a cavity. The cavity may be an open or closed cavity. Further, it may be continuous or isolated.
For example, a cavity with both ends open as in a hollow fiber may be used. In addition, an isolated cavity obtained by adding a foaming agent to a polymer and foaming the polymer may be used. In addition, many holes may be exposed on the surface of the molded product.

The number of the cavities is to be determined according to the purpose and application, and is not particularly limited. That is, a multi-hollow fiber (lotus-shaped hollow) -shaped hollow having a large number of hollow portions, or a single hollow portion such as a core-sheath fiber may be used. There is no size.

Next, a conductive material which is the second essential requirement of the present invention will be described.

In the present invention, a conductive substance is contained at least inside.

The conductive material of the present invention refers to a particle-like, extremely short fibrous, or flake-like material, and does not refer to a long wire. Wires and the like do not meet the purpose of the present invention because of their low moldability.

Examples of such conductive substances include various inorganic substances, and organic substances such as polyacetylene, polyparaphenylene, polypyrrole, and polyphenylene sulfide containing various dopants. Further, there may be mentioned those obtained by coating various metals and the like on various polymer fine particles and the like.
In addition, various types of carbon black, copper, silver, nickel, aluminum, tin, ammothine, iron, zinc, titanium, indium, and oxides, compounds, alloys, and the like thereof can also be used.
Also, various phthalocyanines, which are a kind of organometallic compounds, can be mentioned. These various conventionally known ones can be applied and are not particularly limited. However, more preferred are metals and alloys and their compounds (including organic compounds such as phthalocyanine), and various carbon blacks. These materials are particularly preferable because they are not denatured by heat or atmosphere. Various carbon blacks and metal compounds are particularly preferable because they are not easily modified by heat or environment. That is, examples include zinc oxide, various tin oxides, titanium oxide, copper iodide, titanium nitride, silicon nitride, magnetic iron oxide, copper sulfide, and indium oxide.

In addition, a conductive material of fine particles is particularly preferable because it does not relatively impair the strength of the resin molded article and does not impair the molding of the liquid crystal resin molded article.
Metal compounds are particularly preferred because they can be formed into ultrafine particles.

The conductive substance according to the present invention exists inside the liquid crystal resin in a layered structure and / or a streak structure. Thereby, a liquid crystal resin molded article having high conductivity and / or high strength can be obtained. As a matter of course, a composite of a layer and a streak structure may be used.

In the present invention, the layers and stripes include not only continuous stripes and continuous layers, but also discontinuous stripes and discontinuous layers. Therefore, as a matter of course, a core-sheath fiber in which a conductive component is contained in a core is naturally included in the present invention. The number of muscles and the number of layers are therefore not limited, and include one (layer) to many existing ones. For example, in the case of a so-called polymer array having a sea-island structure, a so-called exfoliated splitting fiber, or the like, a case where the island component is a conductive streak is an example where a large number of conductive streaks are present. In the present invention, such a conductive portion is preferably present at least inside the liquid crystal resin molded product.
As a matter of course, the article may be exposed on the surface of the molded article.

It is needless to say that the polymer constituting the streaks and the layered structure may be the same liquid crystal resin as the liquid crystal resin, but may be formed of a non-liquid crystal resin. Since the non-liquid crystal resin is relatively resistant to fatigue resistance and high deformation, it often has an excellent ability to contain other substances, that is, conductive fine particles. Therefore, molding is easy even if a large amount of a conductive substance is added to the non-liquid crystal resin.

As the non-liquid crystal resin, conventionally known various polymers can be applied, and there is no particular limitation.

Various aliphatic nylons, aromatic nylons such as 12T nylon containing terephthalic acid or isophthalic acid as an acid component, copolymer nylons of nylon 66 and 6T nylon, various polyesters, polyethylene and various other types Polyolefin resins, sulfur-containing aromatic polymers such as polyphenylene sulfide, various polyether ketones, various aromatic polyethers, various aromatic polyether sulfones, and the like. The combination of these polymers and liquid crystal resin should be determined according to the type of liquid crystal resin. Particularly preferred is that the polymer is a polymer that easily absorbs water to some extent.

Examples of such a polymer include nylon 6, various copolymers, especially nylon and polyester obtained by copolymerizing polyethylene glycol, polyester obtained by copolymerizing phthalic acid having a sulfonic acid group, and polyphenylene sulfide sulfone. Aromatic polyether sulfone is also included. Particularly preferred are the following.

Nylon 6 and / or its copolymer, Nylon 61
0 and / or its copolymer, nylon 66 and / or its copolymer, nylon 46 and / or its copolymer, polyethylene and / or its copolymer, polypropylene and / or its copolymer, polyethylene terephthalate and / Or its copolymer, polybutylene terephthalate and / or its copolymer, polyethylene naphthalate and / or its copolymer, polyarylene sulfide and / or its copolymer,
Polyarylene ether and / or its copolymer.

Since the melting point and the fluidity of the liquid crystal resin vary greatly depending on the composition, it is necessary to thoroughly study the polymer before using such a polymer.

The added amount of the conductive substance in such a layered or streaked structure is preferably at least 5% by weight. More preferably, 15% by weight or more is added. It is particularly preferred that 30% by weight or more of a conductive substance is added to the polymer.

By doing so, a molded article having high conductivity can be obtained. The field where the effect of the present invention is particularly exhibited is a field where a certain degree of strength is required as a resin molded product. That is, fibers and films. Conventionally, such a molded product has been produced by stretching, and it has been difficult to impart conductivity by adding fine particles or the like. That is, even if a highly conductive material was obtained in the unstretched state, the current state was that the conductivity was lowered by stretching. However, it is also true that the material has no physical properties unless stretched, and there was no solution to this problem. In the case of a liquid crystal resin, the strength can be increased without stretching. It is presumed that the reason why the highly conductive molded article of the present invention has particularly high strength and is highly conductive is that the liquid crystal resin does not need to be stretched.

The molded product of the present invention is mainly composed of a liquid crystal resin and a conductive material, but also contains other polymers, plasticity, light-proofing agents, terminal terminators, fluorescent brighteners, flame retardants, etc. It may be.

Also, to improve the compatibility between the liquid crystal resin and conductive materials,
It is particularly preferable to add various additives or to modify the liquid crystal resin, other polymers, etc. in order to improve the compatibility of the liquid crystal resin with other polymers.

 Next, a method for producing the molded article of the present invention will be described.

When conductive substances are present in the form of stripes or layers in the liquid crystal resin, it is preferable to form a composite of a polymer rich in conductive substances and a polymer to which no and / or a small amount of conductive substances are added. . The method of composite molding is not particularly limited, and conventionally known methods can be widely applied. Further, even when there is a cavity in the liquid crystal resin molded product, a conventional method of manufacturing hollow fibers can be applied, and there is no particular limitation.

Since the liquid crystal resin is sometimes made infusible depending on the conductive material, it is necessary to control the melting atmosphere when melt molding the liquid crystal resin and the conductive material.
That is, it is preferable that both are melted under an inert gas such as nitrogen gas or a vacuum.

In particular, when it is desired to form a high-strength and conductive liquid crystal resin molded product, it is necessary to treat the molded product under a flow of an inert gas such as nitrogen gas or under vacuum at 200 ° C. or higher to solid-state polymerize the liquid crystal resin. preferable. Then, for example, if it is a fiber, 1
5g / (denier) or more and highly conductive fiber can be easily formed.

In particular, in order to make the liquid crystal resin infusible, the molded product is heat-treated under a high-temperature vacuum or nitrogen gas flow, and the solid-phase polymerized liquid crystal resin molded product is further heat-treated to a temperature equal to or higher than the melting point of the liquid crystal resin. It is made infusible by a method or heat treatment in an atmosphere in which fine particles of at least one compound of chromium, cobalt, and iron and oxygen are present. Activated carbon,
The liquid crystal resin becomes infusible when heat treatment is performed in an atmosphere in which oxygen is present together with carbon fine powder or the like.

It is to be noted that there is no problem at all adding conductivity to the conductive liquid crystal resin molded product by further providing a conductive material or the like.

The conductive molded article of the present invention can be widely and widely developed in the following fields by utilizing such characteristics.

Electromagnetic wave sealing base material, electromagnetic wave sealing wall material, electromagnetic wave sealing blind, electromagnetic wave sealing structural material, electromagnetic wave sealing ceiling material, electromagnetic wave sealing FRP reinforcement material, electromagnetic wave sealing napping, electromagnetic wave sealing helmet, magnetic wave sealing Plywood reinforcing material, conductive molded products, clothing for magnetic wave sealing, conductive fibers, conductive films, conductive filters, conductive base materials, conductive flooring, conductive wires, conductive plywood base materials,

 Hereinafter, the present invention will be described in more detail with reference to examples.

Needless to say, the present invention is not limited to these embodiments.
