Description
Использование 1-15Д ;олизного лиглипа дли и;)лучени различных типов пластических масс затруднено те:л, что получпемые смол ные композиции па основе продуктов конденсации лигнина, фенола и формальдегида (смолы ФЛФ) характеризовались более низкими физикомеханическими покЕзатела.ми, в частности, в отношении динамического (ударно о) изгиба, чем станда1Г иые ирессиздели на основе фенопластов.The use of 1–15D; olysic liglyp length and;) radiation of various types of plastics is difficult: l, that the obtained resin compositions on the basis of condensation products of lignin, phenol and formaldehyde (FLP resin) were characterized by lower physicomechanical materials, in particular, in relation to the dynamic (shock) bending, than standard stresses on the basis of phenoplasts.
редлагаемый cnocot) получени нрсссовочных композиции устран ет указанные недостатки и р.чс;ш;(1 ет сырьевую базу производства прессовочных композиции. Получаемые прессовочные композиции позвол ют нолучать издели , характеризующиес высокой текучестью, высокой водосгоикосгью (приззс воды 0,1-0,2% за 48 час.), высокой ударной в зкостью поиышенны.ми л,иэлектрическими свойствами (пробой 40--60 KZJMM) и значительно более высокой огнеупорностью, че.м фенопласты. The proposed cnocot) for producing compressed compositions eliminates these drawbacks and rss; w; (1 em raw material base for the production of pressing compositions. The resulting pressing compositions allow to obtain products with high fluidity, high water and waste (water prizos 0.1-0.2 % in 48 hours.), high toughness of visibility, and electrical properties (breakdown 40--60 KZJMM) and much higher refractoriness, in m of phenoplasts.
Отличительна особенность описываемого способа заключаетс в том, что в качестве смол ной основы примен ют сплавы лигнинофенольио-формальдегидных смол с полихлорвипилом или сополимерами хлорвинила и в нилиденхлорида или вмес1о лигпино-фенольно-формальдегидной примен ют смолу, полученную при взаимодействии с фенолом и формалином гидролизного лигнина или продуктов его частичного омылени .A distinctive feature of the described method is that alloys of ligninophenolio-formaldehyde resins with polyvinyl chloride or vinyl chloride copolymers and nilidenechloride or instead of ligpine-phenol-formaldehyde copolymers are used in the quality of the resin base, and there is no way to use the same pattern; products of its partial saponification.
Несмотр на то. что полихлорвинил вл етс TepiioruacTOM, его сплавы с лигнипо-феиольно-формальдегидным поликонденсатом позвол ют получать издели , не уступающие но теалостоикост: гермореактивным фенопласгам.In spite of that. that polyvinyl chloride is TepiioruacTOM, its alloys with lignip-feiol-formaldehyde polycondensate make it possible to obtain products that are not inferior but also stable: friable plasma phenol.
Пример 1. 100 г смолообразного продукта конденсации фенола (100 г) и лигнина (90-100 г), полученного путем взаимоделстви указанных веществ при 140-170° в присутствии 0,5-1%-ной серной кислоты, расплавл ют на вальцах при 100-120°, после чего (наExample 1. 100 g of a resinous condensation product of phenol (100 g) and lignin (90-100 g), obtained by the interaction of these substances at 140-170 ° in the presence of 0.5-1% sulfuric acid, is melted on a roller at 100-120 °, then (on
