摘要:
The invention relates to a treatment composition for timber or wood including fire-retardant and either a crosslinking agent or a fixing agent or both, whereby the composition is boron- and halogen-free.
摘要:
Ethyleneamine polyphosphates are doped with organo silanes and hydrophilic fumed metal oxides such as hydrophilic fumed silica. Such doped EAPPA can then be added to polymers, with subsequently formed FR polymer having improved resistance to becoming sticky in humid air. These compositions are inherently drip resistant in a flame. Substantial addition of hydrophilic fumed silica stops stickiness in air and improves FR as measured by LOI.
摘要:
The invention relates to flame retardant compositions for imparting flame retardancy to a wood fiber-based material selected from plywood, chipboard, HDF, LDF, and MDF building panels or OSB building panels.
摘要:
The invention relates to an agent,in particular a flame retarding agent and/or a fire retarding agent, for reducing the combustibility and flammability of various materials or matters, e.g. like wood and wood products, textiles, paper, cardboard, fibers and fabrics, paints, including composites and/or composite materials therewith, the manufacture of the composition and methods of using the agent and/or the corresponding combination of its constituents to reduce combustibility and flammability. An exemplary composition in dry form (powder) for 1 l of aqueous solvent, in particular for 1 l of water, contains borax in an amount of 30 to 70 wt.-%, boric acid of 30 to 70 wt.-%, sodium chloride (NaCl) in a maximum amount of less than 5 wt.-%, and, if desired, urea in an amount up to 5 g; based in each case on the composition as 100 wt.-%. However, the compositions are preferably free from urea.
摘要:
A method for sulphation and phosphorylation of a wooden body to impart anti-flame properties to the substrate wherein at least one phosphonic acid of the formula (I) is used PO(OH) 2 -R-PO(OH) 2 as a catalyst for sulphation and phosphorylating agent, and the relative wooden body.
摘要:
Disclosed herein are flame retardant systems which include a flame retardant adduct and a target material. The flame retardant adduct includes vinyl phosphonic acid (VPA), vinyl phosphonic acid dimethyl ester (VPSDME), or a derivative thereof and an amine. The flame retardant adduct is crosslinked with the target material to form the flame retardant system.
