본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

페놀과 포르마린을 반응시킴에 있어서 1차 반응을 산성 촉매하에서 반응시키고 2차반응을 알카리 촉매하에서 반응시킨 노브락-레졸형의 반응물을 약염기성 금속산화물 또는 금속석금과 3차반응시켜 페놀포르마린수지를 얻은 다음 이를 로진, 에폭시화유 및 초산칼슘의 반응물과 제차 반응시킨 다음 여기에 다가알콜을 첨가하여 반응시키는 방법을 특징으로 하는 고융점의 로진 변성 페놀수지의 제법.In the reaction between phenol and formarin, the phenol-formin resin was reacted with a weakly basic metal oxide or a metal slab by reacting with a weakly basic metal oxide or a metal slab reacted with a primary reaction under an acidic catalyst and a secondary reaction under an alkali catalyst. The method for producing a high-melting rosin-modified phenolic resin, characterized in that the reaction is carried out with a reactant of rosin, epoxidized oil and calcium acetate, and then a polyhydric alcohol is added thereto. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
