Description

Известен способ получени  пластических масс на основе термореактивной фенольно-формальдегидной смолы и органических наполнителей (целлюлозы, древесины или смеси лигнина с древесной мукой), называемый «сухим вальцовым методом, а способ смешени  наполнител  со смолой, наход щейс  в водном или спиртовом растворе или в состо нии водной эмульсии, называемый «мокрым методом. При применении этих способов затрудн ютс  сушка пропитанного наполнител , регенераци  растворител , вальцевание некоторых смол.A known method for producing plastics based on a thermosetting phenolic formaldehyde resin and organic fillers (cellulose, wood or a mixture of lignin and wood flour) is called a "dry roller method, and a method of mixing the filler with a resin in aqueous or alcoholic solution or water emulsion, called the “wet method. When using these methods, it is difficult to dry the impregnated filler, to regenerate the solvent, to roll some resins.

Описываемый способ получени  пластмасс, основан на взаимодействии между жидкими фенольно-формальдегидными смолами и наполнител ми , представл ющими собой высокомолекул рные органические соединени  различного строени . При этом в качестве наполнителей примен ют измельченную древесину, сульфатную или натронную целлюлозу и лигнин. В водной среде получают жидкие продукты конденсации фенолов с альдегидами в присутствии значительного количества сульфокислот, хорошо растворимых в воде и обладающих склеивающей способностью.The described method of producing plastics is based on the interaction between liquid phenolic-formaldehyde resins and fillers, which are high-molecular organic compounds of various structures. In addition, ground wood, sulphate or soda pulp and lignin are used as fillers. In an aqueous medium, liquid condensation products of phenols with aldehydes are obtained in the presence of a significant amount of sulfonic acids, which are well soluble in water and have an adhesive ability.

В отличие от получени  фенольных спиртов, конденсаци  которых проходит в щелочной среде, здесь примен ют сульфокислоты со средним молекул рным весом 2.50-400, получаемые сульфированием углеводородов нефти, ароматических углеводородов, жирных кислот, терпенов и фенолов.In contrast to the production of phenolic alcohols, whose condensation takes place in an alkaline medium, sulfonic acids with an average molecular weight of 2.50-400, obtained by the sulfonation of petroleum hydrocarbons, aromatic hydrocarbons, fatty acids, terpenes and phenols, are used here.

Растворение сульфокислоты производ т в техническом формалине, в который ввод т фенол, исход  из соотношени  1 моль фенола на 1,5 мол  формальдегида.The dissolution of the sulfonic acid is carried out in technical formalin into which phenol is introduced, starting from the ratio of 1 mol of phenol to 1.5 mol of formaldehyde.

Смесь компонентов оставл ют в течение некоторого времени при комнатной температуре до начала реакции конденсации. Дл  того чтобы температура смеси при 1этом не поднималась выше 30° С, резервуар , в котором происходит конденсаци , снабжают змеевиком дл  охлаждени  и механической мешалкой. При сто нии компонентов наThe mixture of components is left for some time at room temperature before the start of the condensation reaction. In order to keep the temperature of the mixture at this temperature above 30 ° C, the tank in which the condensation takes place is supplied with a cooling coil and a mechanical stirrer.
