有し、工業的分野、日常生活分野に広範囲な用途
を持つているが、反面これらの諸特性により加工
が困難である。(2) Conventional technology Tetrafluoroethylene resin (hereinafter referred to as "PTFE")
As is well known, it has excellent properties such as excellent chemical resistance, heat resistance, electrical insulation, self-lubricating properties, and non-stick properties, and has a wide range of applications in industrial and daily life fields. However, on the other hand, these characteristics make it difficult to process.
PTFEは327℃で融解しはじめるが、融点以上
でも軟化流動しないので、PTFEは一般の熱可塑
性樹脂と同じようにスクリユー押出、射出成型、
圧延成型等の方法では成形することができない。 PTFE begins to melt at 327°C, but it does not soften or flow even above its melting point, so PTFE can be processed by screw extrusion, injection molding, etc. like general thermoplastic resins.
It cannot be formed by methods such as rolling.
このため、耐熱性繊維材にPTFE層を形成する
場合の従来の方法としては、PTFEの紛末、水性
分散液またはペーストを、塗布または浸漬等によ
り耐熱性繊維材に被覆又は含浸させた後、この
PTFEを加熱焼成する方法がある。 Therefore, the conventional method for forming a PTFE layer on a heat-resistant fibrous material is to coat or impregnate the heat-resistant fibrous material with PTFE powder, aqueous dispersion, or paste by coating or dipping. this
There is a method of heating and firing PTFE.
従来、この方法によつて耐熱性繊維材の表面に
PTFEの加熱焼成層を形成する場合、PTFEの水

90℃の温度で約５分乾燥し、続いて370℃〜400℃
の温度で10〜20分間焼成するのが通常であつた。
また、耐熱性繊維の表面のPTFE層の厚みより厚
く形成する場合には、上記の塗布、焼成を繰り返
して行なつている。 Traditionally, this method has been used to coat the surface of heat-resistant fiber materials.
When forming a heat-sintered layer of PTFE, a heat-resistant fiber material is coated with an aqueous dispersion of PTFE in an amount of 20μ or less by coating, dipping, etc.
Dry at a temperature of 90℃ for about 5 minutes, followed by 370℃~400℃
It was usual to bake at a temperature of 10 to 20 minutes.
In addition, when forming a layer thicker than the PTFE layer on the surface of the heat-resistant fiber, the above coating and baking are repeated.
しかしながら、上記のようにPTFEの焼成に長
時間をかけた場合、内部の耐熱性繊維材にも高熱
がかかるので、耐熱性繊維材の強度が劣化すると
いう問題がある。例えば、ガラス繊維の場合、約
600℃以上の耐熱性を示すが、ガラス繊維自体の
強度は、300℃の加熱下でオリジナル強度に対す
る強度保持率が約72％、350℃で約57％、400℃で
約42％の強度に劣化する。 However, when PTFE is fired for a long time as described above, high heat is also applied to the internal heat-resistant fiber material, resulting in a problem that the strength of the heat-resistant fiber material deteriorates. For example, for glass fiber, approx.
It exhibits heat resistance above 600℃, but the strength of the glass fiber itself is about 72% of the original strength when heated at 300℃, about 57% at 350℃, and about 42% at 400℃. to degrade.
また、全芳香族ポリアミドの場合は、300℃の
加熱下でオリジナル強度に対する強度保持率が約
48％、350℃で約30％、400℃で約22％の強度に劣
化する。 In addition, in the case of fully aromatic polyamide, the strength retention rate compared to the original strength under heating at 300℃ is approximately
The strength deteriorates by 48%, about 30% at 350℃, and about 22% at 400℃.
したがつて、上記従来の方法により、耐熱性繊
維材の表面にPTFEの加熱焼成層を有する弗素樹
脂複合材を製造した場合、焼成によつて耐熱性繊
維の強度が劣化するので、複合材として十分な強
度が得られなかつた。 Therefore, when a fluororesin composite material having a heat-sintered layer of PTFE on the surface of a heat-resistant fiber material is produced by the conventional method described above, the strength of the heat-resistant fiber deteriorates due to baking, so it cannot be used as a composite material. Sufficient strength could not be obtained.

造方法において、上記加熱焼成の際における焼成
温度ｘと焼成時間ｔとの関係を次式により規制し
たものである。 In order to produce the above-mentioned composite material, the present invention provides a method for producing a fluororesin composite material in which a heat-resistant fiber material is coated or impregnated with PTFE, and then the PTFE is heated and fired. The relationship between firing temperature x and firing time t is regulated by the following equation.
−0.147x＋170≧ｔ・ｘ≧−0.042x＋45
但し、ｘ≧400℃
(5) 作用
上記の式は実験的に得られたものであり、この

からず耐熱性繊維材の強度劣化を防止することが
できているものと思われる。 −0.147x＋170≧t・x≧−0.042x＋45 However, x≧400℃ (5) Effect The above formula was obtained experimentally, and when the above composite is fired to satisfy this formula,
The above composite is fired at high temperature and in a short time. Therefore, it is likely that in the above composite, only the PTFE layer is fired, and the internal heat-resistant fiber material is not exposed to high heat, thereby preventing the strength of the heat-resistant fiber material from deteriorating.
上記の式をグラフで示すと第２図のとおりであ
り、このグラフから、この発明において許容され

0.042x＋45，ｘ≧400の３本の直線で囲まれた範
囲であることがわかり、また、ｙ＝txであるの
で、ｔが可変の場合、焼成温度はx1〜x2の範囲で
許容されることもわかる。 The above formula is shown in a graph as shown in Figure 2. From this graph, the firing zone allowed in this invention is y≦-0.147x+170, y≧-
It can be seen that the range is surrounded by three straight lines: 0.042x+45, x≧400, and since y=tx, if t is variable, the firing temperature is allowed within the range of x 1 to x 2 . I also understand that.

決定し、その焼成温度に基づいて焼成時間ｔ、す
なわち、焼成炉の長さｌと耐熱性繊維材の走行速
度ｖとの関係ｌ／ｖを決定することもできる。 Therefore, when PTFE coated or impregnated with the heat-resistant fiber material is fired by running the heat-resistant fiber material at a predetermined speed through the kiln, the length of the kiln is l.
The firing time t is determined by the traveling speed v of the heat-resistant fiber material and
is determined by l/v, so if the temperature in the firing furnace is set in the range of x 1 to x 2 at this time, the above equation will be satisfied. Similarly, it is also possible to first determine the firing temperature, and then determine the firing time t based on the firing temperature, that is, the relationship l/v between the length l of the firing furnace and the running speed v of the heat-resistant fiber material. .
