КАТАЛИТИЧЕСКАЯ АКТИВНОСТЬ ПРИРОДНЫХ И МОДИФИЦИРОВАННЫХ СОРБЕНТОВ, ИСПОЛЬЗУЕМЫХ В КАЧЕСТВЕ НАПОЛНИТЕЛЕЙ КЛЕЕВЫХ КОМПОЗИЦИЙ
Аннотация и ключевые слова
Аннотация (русский):
Catalytic activity of natural and acid/alkali activated alumosilicates was studied by means of methylbutynol conversion. The changes in conversion were caused by the ratio of acidic and basic sites as a result of modification.

Ключевые слова:
catalytic test reaction, natural alumosilicates, acid and alkaline treatment, basic and acidic sites

Introduction

Natural and synthetic polymers are used in gluing compositions not only as film-formers or binders but also as fillers, directionally changing such specific properties as material strength, flexibility, toughness, adhesion, haze, conductivity, and many others, as well as reducing the cost of the product [1]. Aluminosilicate fillers can be considered as inorganic polymers, the structure of which is represented by continuous tetrahedral and/or octahedral sheets formed as a result of condensation of silica-oxygen tetrahedra SiO4 and/or octahedral AlO6 [2, 3]. Such groupings (tetrahedral and octahedral) are the repeating units of an inorganic heteropolymer.
