Abstract
Description
【発明の詳細な説明】 〔技術分野〕 積層板用樹脂の製造技術の分野に属する。[Detailed description of the invention] 〔Technical field〕 It belongs to the field of manufacturing technology for resin for laminates.
紙、フェノールから構成される積層板において桐油変性
をおこなった樹脂を用いたものは従来、電気性能の点で
要求を満たさない場合があった。Conventionally, laminates made of paper and phenol using resin modified with tung oil sometimes did not meet the requirements in terms of electrical performance.
またフェノールと桐油を反応させた後に行なうホルムア
ルデヒドを加えCの2次反応で触媒を多く必要とするこ
とからコスト面の問題があった。Furthermore, the secondary reaction of C with formaldehyde, which is carried out after the reaction of phenol and tung oil, requires a large amount of catalyst, which poses a cost problem.
本発明では紙フェノール積層板における電気性能の改善
及び積層板に用いる樹脂の合成過程における触媒のトリ
エチルアミンの使用縫の削ak目的とした。The present invention aims to improve the electrical performance of paper phenol laminates and to eliminate the use of triethylamine as a catalyst in the process of synthesizing the resin used in the laminates.
積層板の特性としてa 気性能の良いことが要求される
が、そのためには樹脂中のカルボン酸を少なくすること
か必要であることを見い出した。The laminate is required to have good aeration properties, and we have discovered that to achieve this, it is necessary to reduce the amount of carboxylic acid in the resin.

化子もたらす。水の量は少なすぎるとゲル化がおこり、
多すぎると加水分解物が増加する。In order to reduce the amount of carboxylic acid, it is necessary to suppress the production of hydrolysates produced during the reaction between phenol and tung oil. Therefore, it has been found that in order to suppress the hydrolyzate lit, it is necessary to appropriately determine the amounts of the catalyst p-toluenesulfonic acid and water added in the reaction between phenol and tung oil (first reaction). The catalyst para-toluenesulfonic acid is used in a weight ratio of 0.1% to 0.5% based on the total formulation. If the amount is less than this range, addition of phenol to tung oil, which is the purpose of the reaction, will occur. Moreover, if the amount exceeds this range, the amount of hydrolyzate increases too much, which deteriorates the performance. If the amount of water is too small, gelation will occur,
If it is too large, the amount of hydrolyzate increases.

and the blending ratio of water and paratoluenesulfonic acid to the total blend is rLo, 5 to 4, and 0.1, respectively.
It has been found that it is necessary to set the value to 0.5 cm.

ができコスト低減に効果がある。After the primary reaction is completed, the primary product is reacted with formaldehyde (secondary reaction), and toluethylamine is used as a catalyst to be added at this time. Furthermore, in order to promote the reaction, V must be slightly alkaline, so if there is a large amount of hydrolyzate, a large amount of triethylamine is required due to the influence of the carboxylic acid contained therein. 7JD water decomposition product amount'trg
By reducing the amount of triethylamine, the total amount of triethylamine can be reduced, which is effective in reducing costs.
