Изобретение относитс к технике отверждени фенолформальдегидных смол, оно может быть использовано при приготовлении быстроотверждающихс покрытий, в производстве литых смол, клеевых составов и пенопластов.The invention relates to a technique for curing phenol-formaldehyde resins, it can be used in the preparation of fast-curing coatings, in the production of cast resins, adhesives and foams.
Известно использование в качестве отвердителей ангидридов дикарбоновых кислот, однако скорость отверждени при этом недостаточно высока .It is known to use dicarboxylic acids as hardeners of anhydrides, however, the curing rate is not high enough.
Цель изобретени - интенсификаци процесса отверждени резольных фенолформальдегидных смол. Это достигаетс введением в состав композиции 0,3-5% от веса смолы дихлорангидридов дикарбоновых кислот, например фталевой, адипиновой, себациновой.The purpose of the invention is to intensify the process of curing resole phenol-formaldehyde resins. This is achieved by introducing into the composition 0.3 to 5% by weight of a resin of dicarboxylic acid dichlorides, for example, phthalic, adipic, sebacic.
Отверждение при этом протекает при схеме;Curing at the same time proceeds at the scheme;
