With a view to developing new insulating bio-composites incorporating mainly fibre and flax mucilage, the Environmental Chemistry and Living Interactions Unit (UCEIV) and Van Robaeys Frères, Lin’s teiler located in Flanders Maritime, have started a collaboration since 2015. In order to consider large-scale production, these materials must incorporate improved fire resistance properties. That is why we propose to make them intumescent. This objective will be achieved by two complementary means, comprising, on the one hand, the modification of the constituents of composites (resin, fibre, polysaccharide) by chemical grafting of groups improving the thermal properties (derivates of phosphorus, silica) and, on the other hand, by the formulation of fibre assemblies/flame retardants (metal oxides, clay, expanded graphite). Today, based on our experience in the development of bio-based flax-based materials, an application development towards a TRL 6 is targeted to the extent that these new materials would be held in fire. Thus, our strategy is based on fireproofing of components already obtained by (i) the addition of metal hydroxides and expanded graphite for formulation of flax fibre rigid boards, (ii) phosphorylation of epoxy resin and mucilage, (iii) grafting of pyrogenic silica amino derivatives to flax fibres.

Dans l’optique d’élaborer de nouveaux bio-composites isolants incorporant majoritairement des fibres et du mucilage de lin, l’Unité de Chimie Environnementale et Interactions sur le Vivant (UCEIV) et l’entreprise Van Robaeys Frères, teilleur de Lin situé en Flandre Maritime, ont entamé une collaboration depuis 2015. Afin d’envisager une production à grande échelle, ces matériaux doivent intégrer des propriétés de tenue au feu améliorées. C’est la raison pour laquelle nous proposons de les rendre intumescent. Cet objectif sera réalisé par deux voies complémentaires, comprenant d’une part la modification des constituants des composites (résine, fibre, polysaccharide) par greffage chimique de groupements améliorant les propriétés thermiques (dérivés de phosphore, de silice) et d’autre part, via la formulation d’assemblages fibres/retardateurs de flamme (oxydes métalliques, argile, graphite expansé). Aujourd’hui, partant de notre expérience dans l’élaboration de matériaux bio-sourcés à base de lin, un développement applicatif vers un TRL 6 est visé dans la mesure où la tenue au feu de ces nouveaux matériaux serait effective. Ainsi, notre stratégie repose sur l’ignifugation des composants déjà obtenus par (i) l’addition d’hydroxydes métalliques et de graphite expansé pour une formulation des panneaux rigides de fibres de lin, (ii) la phosphorylation de la résine époxy et du mucilage, (iii) le greffage de dérivés aminés de silice pyrogénique sur les fibres de lin.

With a view to developing new insulating bio-composites incorporating mainly fibre and flax mucilage, the Environmental Chemistry and Living Interactions Unit (UCEIV) and Van Robaeys Frères, Lin’s teiler located in Flanders Maritime, have started a collaboration since 2015. In order to consider large-scale production, these materials must incorporate improved fire resistance properties. That is why we propose to make them intumescent. This objective will be achieved by two complementary means, comprising, on the one hand, the modification of the constituents of composites (resin, fibre, polysaccharide) by chemical grafting of groups improving the thermal properties (derivates of phosphorus, silica) and, on the other hand, by the formulation of fibre assemblies/flame retardants (metal oxides, clay, expanded graphite). Today, based on our experience in the development of bio-based flax-based materials, an application development towards a TRL 6 is targeted to the extent that these new materials would be held in fire. Thus, our strategy is based on fireproofing of components already obtained by (i) the addition of metal hydroxides and expanded graphite for formulation of flax fibre rigid boards, (ii) phosphorylation of epoxy resin and mucilage, (iii) grafting of pyrogenic silica amino derivatives to flax fibres.
