A phenolic resin composition with characteristics is provided. In other words, the present invention does not use curing aids made of conventional acids such as metal oxides or sulfonic acids that cause thickening of phenolic resins, and moreover, by adding a very small amount of phenol sulfonic acid, metals and gold can be cured.

有機酸塩等を触媒として用いて反応させる。First, in the present invention, any suitable dimethylene ether type liquid phenol resin can be used. It is synthesized by using a formaldehyde source and a phenol source as raw materials, preferably by reacting them using a catalyst. In this case, formaldehyde sources include formaldehyde, paraformaldehyde,
Formaldehyde aqueous solution, etc. can be used, and as a phenol source, phenone, cresol, resorcinol, etc. can be used. Usually, this synthesis reaction uses a formaldehyde/phenol raw material molar ratio of 0.3 to 3.0,
Preferably in the range of 0.5 to 2.5, the reaction is carried out using a metal organic acid salt or the like as a catalyst.

Then, it is immediately left to stand to remove the precipitate. The dehydration conditions are generally 10 to 100 torr of vacuum and a final dehydration temperature of 20 to 90°C. This dehydration reduces free water to 2.0 to 5.0
It is preferable to set it to about %.

.. Use at a rate of about 40PHR. Addition of phenolsulfonic acid above 0.5 PHR results in rapid thickening of the resin and is also not advantageous in terms of metal and mold corrosion.

Examples of this inorganic filler include silica and alumina, which are used together with glass fibers that are also useful as SMC and BMC. In this case, an acidic region with a pH of 7 or less,
Alternatively, it is necessary to use a substance in the neutral range, with a pH of 7.
If it exceeds the above range, it is not preferable because it inhibits the curing of the resin.
