RESOL TYPE PHENOLIC RESIN CONTAINING LOW WATER CONTENT AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to a kind of resol resin have low water content and and its production method, more specifically, being related to a kind of low viscosity resol resin, it is maintained by neutralizing at least one acid selected from including hydrogen chloride, phosphorous acid, formalin of the salicylic acid in specific condensation reaction condition and phenol, the water with low content; And it is a kind of production it is identical. The resol resin has low water content, in accordance with the invention it is possible to which maintenance has the low viscosity of the water of low content simultaneously, thus mixing is steadily easily-controllable is being handled; And high water content and high viscosity caused by the decline of product quality can be prevented, in existing phenolic resin, therefore is expected to be applied to various fields, including industry and construction site, wherein phenolic resin can be applied. ;The 2014 of copyright KIPO submissions
