Zinc borate and magnesium hydroxide reduce smoke

Synergistic action of zinc borate or magnesium hydroxide with phosphorus were demonstrated in novel PIN FR coatings applied to 4mm plywood board (up to 75x75 cm, tunnel, cabinet tests, cone calorimeter and smoke density tests). A cyclic phosphate ester was reacted with zinc borate or with magnesium hydroxide, then incorporated into an amino resin, then brush applied to the plywood, with several applications to result in a 0.4 mm coating. Different levels of minerals were tested (0 – 7% by mass).

STPP and pomegranate FR for cotton

In laboratory tests, 3% STPP ‘(sodium tri poly phosphate, the mineral phosphate salt widely used last century in detergents) and pomegranate rind extract were tested as a “green” PIN flame retardant treatment for cotton (150 g/mm2 woven fabric). The extract was obtained by high temperature boiling in water of chopped waste pomegranate rinds.

Mineral functionalised LDHs as PIN FRs for epoxy

Functionalised layered double hydroxide (LDH) were synthesised in a one-step reaction by mixing a solution of organic compounds (SDBS sodium dodecylbenzenesulfonate, sCD hydroxypropyl-sulfobutyl-beta-cyclodextrin and taurine) with solutions of magnesium nitrate Mg(NO3)2 and aluminium nitrate Al(NO3)3 and adjusting pH, then filtering and drying the resulting slurry.

Renewable cellulose and clay for FR coating

Researchers have tested layer-by-layer deposition (LbL) coating on PET film and on polyurethane foam (not specified), alternating cellulose nano-fibrils and clay. The cellulose nano-fibrils were extracted from pulp fibres, then cationised. These fibrils are expected to show good mechanical properties because of crystallinity.
