Abstract

The development and study of strong binder systems with self-healing properties based on gelatine modified with tannin or transglutaminase for the manufacture of greener stone wool and related materials is presented.

Highlights

  • Volcanic activity at Hawaii produces bundles of a fibrous material which is known as the hair of the volcanic goddess Queen Pele in the local folklore.[1]

  • This paper has presented the development, study and discussion of highly promising binder systems for stone wool and related materials based on non-toxic and natural biopolymer components: gelatine modified with tannin or transglutaminase

  • The gelatinebased binder compositions were able to cure at ambient temperature and the development of these binder systems was achieved using a newly developed and highly versatile composite bar model method based on the use of stone shots with submillimetre diameters having the same chemical composition as the actual stone wool fibres

Summary

Introduction

Volcanic activity at Hawaii produces bundles of a fibrous material which is known as the hair of the volcanic goddess Queen Pele in the local folklore.[1]. The composite bar model method was applied to the first systematic study of the binder systems based on gelatine modified with the addition of 3%, 5%, 10%, 20%, 30% and 50% tannin or transglutaminase, respectively, calculated on basis of the gelatine component.
