- DESCRIPTION TITLE FIRE-RESISTANT GLAZING
- the present invention relates to the field of fire-resistant glazing. It relates in particular to a method of manufacturing an intumescent coating on a sheet of glass, as well as a glazing comprising a sheet of glass coated with an intumescent coating capable of being obtained by this process.
- Fire-resistant glazing is conventionally formed from a very viscous aqueous solution based on hydrated alkali silicates sealed between two sheets of glass (EP 3023245, WO 2007/118886, WO 2007/053248, EP 2072247, EP 2282889, 053248).
- Other fire-resistant glazing is formed from a layer of solid hydrogel between two sheets of glass, obtained by crosslinking a solution of water-soluble monomers (US 2016/2000077, EP 2330174).
- a solution of water-soluble monomers US 2016/2000077, EP 2330174.
- protection against fire is ensured by the opaque mineral foam formed by the expansion of the layer of silicates due to the evaporation of the water it contains under the effect of heat.
- the hydrogel layer the spread of fire is retarded by the evaporation of water and the inorganic additives contained in the hydrogel layer.
- intumescent organic coatings such as paints or varnishes, developed to improve the fire resistance of building materials.
- Such coatings comprise a polymer binder and an intumescent system generally formed from an acid source such as phosphoric acid or an ammonium polyphosphate, a carbonaceous compound such as a polyol, and an expansion agent such as urea or melamine.
- an acid source such as phosphoric acid or an ammonium polyphosphate
- a carbonaceous compound such as a polyol
- an expansion agent such as urea or melamine
- the object of the present invention is to provide a solid intumescent coating, preferably mainly inorganic, which does not affect the optical properties thereof and exhibits good intumescence.
- a process for manufacturing an intumescent coating on a sheet of glass comprising: - the preparation of a solution of precursors comprising 20 to 80% by weight of material dried; said composition comprising, based on the total weight of dry matter, 10 to 40%, preferably 20 to 35%, of a phosphorus agent and 50 to 90%, preferably 60 to 80%, of hydrolysable silanes; said hydrolyzable silanes comprising 50 to 100% by weight of at least one silane chosen from the silanes of formula I and the silanes of formula II: (I) (R1O) 4 Si (II) R2 k (R1O) 4-k Si wherein each R1 is independently selected from C1-C4 alkyl; k is an integer between 1 and 3; and each R2 is independently selected from C1-
- the present invention also relates to a fire-resistant glazing capable of being obtained by the above process.
- the Applicant has in fact demonstrated that the process according to the invention makes it possible to obtain a mainly inorganic coating in an easy manner and which, after drying, has optical properties compatible with use in glazing.
- the coating has after drying a solid structure facilitating the manufacture, handling and integration of the glazing according to the invention.
- the use of a solid coating associated with sheets of non-tempered glass allows the production of large-size glazing which can be cut to the desired dimensions without the need for sealing the edges with any joint or adhesive.
- the precursor solution comprises, on the basis of the total dry matter, from 50 to 90%, preferably from 55 to 80%, even 60 to 75%, by weight of dry matter of hydrolysable silanes, that is to say say of silanes comprising at least one hydrolysable group.
- Hydrolyzable silanes are typically silicon alkoxides. They can nevertheless comprise other hydrolysable silanes such as chlorosilanes.
- the hydrolyzable silanes comprise at least 50%, preferably at least 70%, or even 90 to 100% by weight relative to the total quantity of hydrolyzable silanes, of at least one silane chosen from the silanes of formula I and the silanes of formula II.
- hydrolysable silanes may in particular comprise 0, or even 10%, to 60%, or even 50%, by weight of at least one silane chosen from the silanes of formula I and 40, or even 50% to 100%, or even 90%, by weight of at least one silane chosen from the silanes of formula II, relative to the total amount of hydrolysable silanes.
- the hydrolysable silanes preferably comprise only silanes chosen from the silanes of formula I or of formula II. More preferentially, the hydrolysable silanes comprise only silanes chosen from the silanes of formula II.
- the hydrolysable silanes comprise at least one silane chosen from the silanes of formula IIa, corresponding to the silanes of formula II in which at least one R2 group comprises an amine, carboxylic acid, ester, epoxy, ether, acrylate, urethane or alcohol, or comprises a carbon chain (linear, cyclic or branched) of 8 or more carbons, in particular an aryl.
- the hydrolyzable silanes comprise at least one silane chosen from the silanes of formula IIb, corresponding to the silanes of formula II in which no R2 group comprises an amine, carboxylic acid, ester, epoxy, ether, acrylate, urethane, alcohol, or with a carbon chain (linear, cyclic or branched) of 8 or more carbons.
- the hydrolysable silanes can also comprise at least one silane chosen from the silanes of formula IIa and at least one silane chosen from the silanes of formula IIb.
- silanes of formula II comprising at least one non-hydrolyzable group
- the intumescent layer thus has a better resistance to ageing.
- the intumescence properties of the layer according to the invention come on the one hand from the formation of an organophosphorus network resulting from the reaction of the phosphorus agent and the organic residues, and on the other hand from the release of large quantities of gas at relatively low temperatures.
- the gases are assumed to originate both from the evaporation of the residual water (free water trapped during gelation or water bound to the network) and the decomposition of the non-hydrolysable R2 group of the silanes of formula II.
- the silanes of formula IIa provide improved intumescent properties. This effect is attributed to the generation of a greater quantity of gas during their decompositions and/or to the formation of a greater quantity of carbonaceous residue.
- the organophosphorus network more flexible than the silica network, allows a foaming of the intumescent coating at low temperature thus quickly forming a protective carbonaceous residue during the exposure to fire of the intumescent coating.
- the hydrolyzable silanes may comprise 10 to 50%, preferably 20 to 40%, of at least one silane chosen from the silanes of formula I, 40 to 80%, preferably 50 to 70 %, of at least one silane chosen from the silanes of formula IIa and 0 to 20%, preferably 0 to 10%, of at least one silane chosen from the silanes of formula IIb.
- they comprise 0 to 20%, preferably 0 to 10%, of at least one silane chosen from the silanes of formula I, 40 to 90, preferably 50 to 80%, of at least a silane chosen from the silanes of formula IIa and 10 to 50%, preferably 20 to 40%, of at least one silane chosen from the silanes of formula IIb.
- they comprise 10 to 60%, preferably 20 to 50%, of at least one silane chosen from the silanes of formula I, 0 to 30%, preferably 0 to 20%, of at least at least one silane chosen from the silanes of formula IIa and 10 to 60%, preferably 20 to 50%, of at least one silane chosen from the silanes of formula IIb.
- they comprise 50 to 100%, preferably 60 to 100%, of at least one silane chosen from the silanes of formula IIa, 0 to 50%, preferably 0 to 40%, of at least one silane chosen from the silanes of formula IIb, and preferably no silane of formula I.
