The present invention will be explained in further detail below.

According to the present invention, it has high strength and high conductivity.

It is surprising that a liquid crystal resin molded product having stable conductivity can be obtained.

The present invention consists of at least two types of materials: a liquid crystal resin and a conductive material.

First, the liquid crystal resin which is the 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 in which the mesogen group is in the main chain.

There are various kinds of such liquid crystal resins, but they can be broadly classified into those made of aromatic polyester and those made of aromatic polyester amide.

Various aromatic polyesters can be used, and conventionally known ones can be used without any particular limitation.

Particularly preferred are liquid crystal resins having the following structural units.

It is also effective to introduce the following structural units It is.

ie. ), etc., which can rotate relatively freely between aromatic rings, or aliphatic diols and aliphatic dicarboxylic acids represented by (where m and n are integers from 2 to 10). Examples include structural units.

Particularly preferable liquid crystal polyarylate resins include those having the following structural formula. That is, here, Σn1=100 in each structural formula. Particularly preferred is that ni of each structural formula is 4 or more. Moreover, various substituents including halogen etc. may be added to each formula.

These materials have high melt moldability and high strength, and also have high melting points and glass transition points, and are particularly preferred.

Next, there are various types of liquid crystal resins made of aromatic polyesteramide, and conventionally known ones can be widely applied, and there are no particular limitations.

The following are particularly preferable:
It is cited as a representative example. That is, the structural unit derived from aminophenol is represented by the following formula.

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

Furthermore, as structural units derived from aromatic dicarboxylic acids, in addition to those listed in the above section of liquid crystal polyarylates, those represented by the following formulas are particularly preferred.

Examples of liquid crystal polyesteramide include those having 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 bonds are coaxial or parallel and oriented in opposite aromatic directions.

Here, AR is at least one aromatic ring having an alkyl or alkoxy substituent having 4 or less carbon atoms, and whose chain extension bonds are coaxial or parallel and point in opposite directions.

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, Σn1=100 in each structural formula. Particularly preferably, ni of each structural formula is 15 or more. Moreover, various substituents including halogen etc. may be added to each formula. These materials have melt moldability similar to liquid crystal resins made of polyarylate, and have high strength.

Note that although the liquid crystal resin of the present invention is originally thermoplastic,
In particular, when heat resistance is required, it is particularly preferable that the liquid crystal resin is infusible.

In addition, when particularly high-strength liquid crystal resin molded products are required,
It is preferable that the molecular weight of the liquid crystal resin is high to some extent. Particularly preferably, the number average molecular weight of the liquid crystal resin is 13,000 or more. moreover.

Preferably, it is 30,000 or more. When it comes to such things,
The strength of the liquid crystal resin molded product is 4Qkg/w! that's all.

It is preferable that the elastic modulus is 2400 kg/f1 or more, which increases the dimensional stability and allows for wide application in many fields.

The form of the liquid crystal resin molded product of the present invention is not particularly limited, and IJ! ! This includes fibers, microfibers, films, chips, plates, rods, square timbers, and various molded products.

When the molded product of the present invention is particularly required to be lightweight and to prevent whitening, it is preferable to have a cavity in the molded product. The cavity may be an open cavity or a closed cavity.

Also, in terms of continuity.

It can be isolated. For example, it may be a cavity open at both ends, such as in a hollow fiber. Alternatively, it may be an isolated cavity such as that obtained by adding a foaming agent to a polymer and causing it to foam. Further, a large number of holes may be exposed on the surface of the molded product.

Note that the number of cavities should be determined depending on the purpose and use, and is not particularly limited. That is,
It is hollow in the form of a multi-hollow fiber (lotus root-shaped hollow) having a large number of hollow parts, or it may be made of only one hollow part like a core-sheath fiber. Also, its size is unknown.

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

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

The conductive material of the present invention refers to particles, very short fibers, and flakes, and does not refer to long wires. Wires and the like have low moldability and therefore do not meet the purpose of the present invention.

Such conductive substances include various inorganic substances, polyacetylene, polyparaphenylene, and polypyrrole. Examples include organic materials such as polyphenylene sulfide containing various dopants. Also included are products in which various metals are coated on various polymer fine particles. Also included are various carbon blanks, copper, silver, nickel, aluminum, tin, antimony, iron, zinc, titanium, indium and oxides thereof, Compound 1 alloys, and the like. Also included are various phthalocyanines, which are a type of organometallic compounds. These various conventionally known materials can be used and are not particularly limited. However, more preferred are metals and alloys, their compounds (including organic compounds such as phthalocyanine), and various carbon blacks. These materials are particularly preferred because they are not denatured by heat or atmosphere. Various carbon blanks and metal compounds are particularly preferred from the viewpoint of being resistant to denaturation by heat or the environment. That is, examples include zinc oxide, various types of tin oxide, titanium pentoxide, copper iodide, titanium nitride, silicon nitride, rlIL iron oxide, copper sulfide, indium oxide, and the like.

In addition, conductive substances in the form of fine particles are particularly preferable because they do not relatively impair the strength of the resin molded product and do not impair the molding of the liquid crystal resin molded product. It is particularly preferred because it can be molded.

These conductive substances may be uniformly dispersed in the liquid crystal resin, but when particularly high conductivity is required or when molding a liquid crystal resin with high strength, it may be necessary to disperse them in a single layer or in a striped form to some extent. It is preferable that there be. Of course, it may be a combination of a single layer and a striped structure.

Note that in the present invention, the term "layered" or "striated" refers to continuous striated,
It also includes not only continuous layered forms, but also discontinuous striped and discontinuous layered forms. Therefore, although it is natural,
A core-sheath fiber whose core contains a conductive component is also naturally included in the present invention. The number of stripes and the number of layers are therefore not limited, and may range from one (layer) to many. For example, in a so-called polymer array having a sea-island structure, a so-called peelable and split type fiber, etc., the case where the island components become conductive streaks is an example of a case where there are a large number of conductive streaks. In the present invention, it is preferable that such a conductive portion be present in a small amount (or at least within the liquid crystal resin molded product), although this is a matter of course.

Cough material may be exposed on the surface of the molded product.

It goes without saying that the polymer constituting the stripes and layered structure may be the same liquid crystal resin as the liquid crystal resin, but it may also be composed of a non-liquid crystal resin. Non-liquid crystal resins are relatively resistant to fatigue and high deformation, so
Others often have an excellent ability to contain other substances, such as conductive fine particles. Therefore, even if a large amount of a conductive material is added to the non-liquid crystal resin, molding is easy.

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

Various aliphatic nylons, 12T nylon with terephthalic acid or isophthalic acid as acid component, nylon 66 and 6
Aromatic nylon including copolymerized nylon with T nylon, various polyesters, various polyolefin resins including polyethylene, sulfur-containing aromatic polymers including polyphenylene sulfide, various polyether ketones, Furthermore, various aromatic polyethers, various aromatic polyether sulfones, etc. can be used. The combination of these polymers and liquid crystal resin should be determined depending on the type of liquid crystal resin. Particularly preferred is a polymer that easily absorbs water to some extent.

Such polymers include nylon 6, various copolymer polymers, especially nylon copolymerized with polyethylene glycol, polyester, polyester copolymerized with phthalic acid to which a sulfonic acid group is added, polyphenylene sulfide sulfone, Also included are aromatic polyether sulfones and the like. Particularly preferable ones include the following.

Nylon 6 and/or its copolymer, nylon 61
0 and/or its copolymer, nylon 66 and/or
or a copolymer thereof, nylon 46 and/or a copolymer thereof, polyethylene and/or a copolymer thereof,
Polypropylene and/or copolymers thereof, polyethylene terephthalate and/or copolymers thereof, polybutylene terephthalate and/or copolymers thereof.

Polyethylene naclate and/or its copolymer, polyarylene sulfide and/or its copolymer, polyarylene ether and/or its copolymer.

Note that the melting point and fluidity of liquid crystal resins vary greatly depending on their composition, so when such polymers are used in combination, it is necessary to thoroughly consider this in advance.

The amount of conductive material added in such a layered or striped structure is 5.
It is preferable that it is at least % by weight. More preferable is 1
It is added in an amount of 5% by weight or more.

Particularly preferred is 30% by weight or more of the conductive substance added to the polymer.

By doing so, a highly conductive molded product can be obtained.

Note that the field in which the effects of the present invention are particularly exhibited are fields in which resin molded products are required to have a certain degree of strength. That is, such molded products, such as L1Ii fibers and films, have conventionally been made by stretching, so it has been difficult to impart conductivity by adding fine particles or the like. That is, even if a highly conductive product can be obtained without being stretched, the current conductivity is reduced by stretching. However, it is also true that the material has no physical properties unless it is stretched, and there has been no solution to this problem. In the case of liquid crystal resin, high strength can be achieved without stretching. The reason why the highly conductive molded product of the present invention is particularly high strength and highly conductive is that
It is estimated that the fact that the liquid crystal resin does not require stretching is a major factor.

2. The molded product of the present invention is mainly composed of a liquid crystal resin and a conductive material, but may also contain other polymers, plasticizers,
A light stabilizer, a terminal stopper, a fluorescent whitening agent, an N reagent, etc. may be contained.

In addition, in order to improve the compatibility between liquid crystal resin and conductive materials, various additives are added, and liquid crystal resins are added to improve the co-solubility of liquid crystal resin and other polymers.

It is also particularly preferred to modify other polymers and the like.

Next, the method for manufacturing the molded product of the present invention will be described.

When the conductive substance is uniformly dispersed in the liquid crystal resin, a method of adding the conductive substance during polymerization of the liquid crystal resin, a method of adding the conductive substance using an extruder, etc. can be widely applied, and there are no particular limitations. .

On the other hand, when a conductive substance exists in the form of streaks or layers in the liquid crystal resin, it is possible to compositely mold a polymer rich in conductive substances and a polymer with no conductive substances added and/or a small amount of conductive substances. is preferable, and the method of composite molding is not particularly limited, and conventionally known methods can be widely used. Further, even if there is a cavity in the liquid crystal resin molded product, the conventional manufacturing method of hollow fiber can be used, and there is no particular limitation.

Note that liquid crystal resin sometimes becomes infusible due to conductive substances, so when melting and molding liquid crystal resin and conductive substances, what should be done? It is necessary to control the atmosphere of melting. That is, both are preferably melted under an inert gas such as nitrogen or vacuum.

In addition, if you want to make a liquid crystal resin molded product with particularly high strength and conductivity, it is possible to solid-phase polymerize the liquid crystal resin by treating the molded product at 200°C or higher under a flow of inert gas such as nitrogen gas or under vacuum. preferable. In this way, 1. For example, if it is a fiber,
Fibers with a weight of 15 g/(denier) or more and high conductivity can be easily produced.

In particular, in order to make the liquid crystal resin infusible, the molded product is heat-treated under a high-temperature vacuum or under a nitrogen gas flow.

The solid phase polymerized liquid crystal resin molded product is further heat-treated to a temperature higher than the melting point of the liquid crystal resin, or in an atmosphere in which fine particles of at least one compound of chromium, cobalt, and iron and oxygen are present. It becomes infusible due to this. In addition, activated carbon, fine carbon powder, etc. can be made infusible by heat treatment in an atmosphere where oxygen is present.

Note that it is equally acceptable to further impart conductivity by further applying a conductive substance to the conductive liquid crystal resin molded article.

The conductive molded article of the present invention can be widely used in the following fields by taking advantage of these characteristics.

Base materials for electromagnetic wave seals, wall materials for electromagnetic wave seals, blinds for electromagnetic wave seals, structural materials for electromagnetic wave seals, ceiling materials for electromagnetic wave seals, reinforcing materials for FRP for electromagnetic wave seals, raised products for electromagnetic wave seals, electromagnetic wave seal helmets, for magnetic wave seals Reinforcing materials for plywood, conductive moldings, clothing for magnetic wave sealing, conductive fibers, conductive films, conductive filters, conductive base materials, conductive flooring materials, conductive wires, base materials for conductive plywood, conductive Rope, conductive friction material, conductive protective gloves, conductive protective gear, conductive tire cord, conductive paper, conductive sliding member, conductive clothing, antistatic fiber, antistatic paper, antistatic wall , antistatic plywood base material, antistatic rope, antistatic sliding member, antistatic tire cord, antistatic floor, antistatic ceiling material, antistatic reinforcing material, base material for dust-free rooms , dust-free clothing, etc. conductive screen gauze,

It goes without saying that the present invention is not limited to these embodiments.
