products based on mineral wool, in particular glass or rock wool, containing
hydrogenated sugars, at least one polycarboxylic acid and a large amount of
at least one epoxysilane.
The manufacture of insulating products based on mineral wool
generally comprises a step of manufacturing glass or rock fibres via a
centrifugation process. On their path between the centrifugation device and
the fibre collection belt, an aqueous sizing composition, also known as a
binder, is vaporized onto the fibres while still hot, and then undergoes a
thermosetting reaction at temperatures of about 200°C.
The phenolic resins that have been used for several decades as
binders are being increasingly replaced with products derived from
renewable sources and which emit very little or no formaldehyde, this
compound being considered as possibly harmful to human health.
It is thus known, for example from US 2011/0 223 364, to bind mineral
fibres with formaldehyde-free aqueous sizing compositions containing, as
heat-curable reagents, carbohydrates and polycarboxylic acids.
However, sizing compositions based on reducing sugars have the
drawback of giving rise to colouring reactions (caramelization, Maillard
reaction) which make it difficult, if not impossible, to obtain clear-coloured
products.
The Applicant proposed in its patent applications 266
and 399 binders based, not on reducing sugars, but on
hydrogenated sugars, also known as sugar alcohols. These reagents have
considerably higher heat stability than reducing sugars and do not give rise to
Maillard and/or caramelization reactions.
Insulating products based on mineral wool and on this new generation
of “green” binders are, however, relatively hygroscopic and conserve their
mechanical properties less well over time than the more coloured products
manufactured with reducing sugars. To compensate for the loss of
mechanical properties after a certain period of ageing of these insulating
products, it is generally necessary to increase the proportion of binder by
about 10% to 20%, which not only increases the cost of the final product, but
also impairs its reaction to fire.
In the course of its investigations directed towards improving the
mechanical properties of insulating products based on mineral wool sized
with “colourless” binders, i.e. manufactured from hydrogenated sugars, the
Applicant has found, surprisingly, that certain compounds, known as
couplers, lead to a spectacular improvement of the mechanical properties of
the insulating products obtained, on condition that they are used at
concentrations higher than those required for their functioning as coupler.
It is widely known and very common practice to use functional silanes
as couplers for improving the adhesion of organic materials to mineral
surfaces such as glass. A functional silane generally comprises at least one,
preferably two or three, hydrolyzable alkoxysilyl functions, which are capable
of reacting with the silanol groups at the surface of glass, and at least one
reactive function (oxirane, amine) borne by a non-hydrolyzable organic
group, bonded to the silicon atom via an Si-C bond. This organic function is
generally chosen so as to be able to react with the organic phase.
To obtain a satisfactory binder-glass coupling effect, it generally
suffices to add less than 1% by weight (of solids) of coupler to the sizing
composition. Admittedly, the prior art contains patent applications which
envisage higher concentrations of coupler (see, for example,
US 2011/0 223 364), but the preferred examples and embodiments generally
mention concentrations close to 0.5%, which is certainly driven by the
relatively high cost of these compounds.
The couplers that are the most widely used are aminosilanes. They
are relatively cheaper than epoxysilanes and have, at neutral pH, a chemical
stability that allows sizing compositions to be prepared a long time in
advance.
Epoxysilanes are not only more expensive than aminosilanes, but also
have the additional drawback in that the epoxy function becomes hydrolyzed
quite rapidly in the presence of water, giving rise to a much less reactive diol.
The present invention is based on the quite surprising discovery that
epoxysilanes, unlike aminosilanes, considerably improve the resistance to
ageing of insulating products based on mineral wool and binders containing
hydrogenated sugars, when they are used in concentrations above about 2%
by weight.
The subject of the present invention is, consequently, an aqueous
sizing composition for insulating products based on mineral wool, comprising
(a) at least one saccharide chosen from reducing sugars, hydrogenated
sugars and a mixture thereof, the proportion of hydrogenated sugars in
the saccharide being between 25% and 100% by weight,
(b) at least one monomeric polycarboxylic acid or a salt or anhydride of such
an acid,
(c) more than 2.0% by weight, relative to the sum of the components (a) and
(b), of at least one epoxysilane.
The component (a) of the sizing composition according to the
invention may consist solely of hydrogenated sugars and be free of reducing
sugars. This embodiment is advantageous since it leads to insulating
products that are particularly sparingly coloured.
The term “comprising” as used in this specification and claims means
“consisting at least in part of”. When interpreting statements in this
specification and claims which include the term “comprising”, other features
besides the features prefaced by this term in each statement can also be
present. Related terms such as “comprise” and “comprises” are to be
interpreted in similar manner.
The term “saccharide” has herein a broader meaning than usually,
since it encompasses not only saccharides in the strict sense, i.e. reducing
sugars or carbohydrates of formula C (H O) bearing at least one aldehyde
n 2 p
or ketone group (reducing group), but also the products of hydrogenation of
these carbohydrates in which the aldehyde or ketone group has been
reduced.
In the present invention, the term “hydrogenated sugar” means all the
products resulting from the reduction of a saccharide chosen from
monosaccharides, disaccharides, oligosaccharides and polysaccharides and
mixtures of these products.
The hydrogenated sugar is preferably a product of hydrogenation of a
starch hydrolysate.
Starch hydrolysates are products obtained by enzymatic and/or acidic
hydrolysis of starch. The degree of hydrolysis is generally characterized by
the dextrose equivalent (DE), defined by the following relationship:
nombre de liaisons glycosidiques rompues
number of broken glycoside bonds
DE = 100 x
nombre de liaisons glycosidiques dans l'amidon initial
number of glycoside bonds in the initial starch
The preferred starch hydrolysates have, before the hydrogenation
step, a DE of between 5 and 99 and advantageously between 10 and 80.
The hydrogenation of the saccharide may be performed via known
methods working under conditions of high hydrogen pressure and high
temperature, in the presence of a catalyst chosen from the elements of
groups IB, IIB, IVB, VI, VII and VIII of the Periodic Table of the Elements,
preferably from the group comprising nickel, platinum, palladium, cobalt and
molybdenum, and mixtures thereof. The preferred catalyst is Raney nickel.
The hydrogenation transforms the sugar or the mixture of sugars (starch
hydrolysate) into polyols or sugar alcohols.
As examples of hydrogenated sugars, mention may be made of
erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol,
cellobitol, palatinitol, maltotritol and the products of hydrogenation of starch
hydrolysates.
The products of hydrogenation of starch hydrolysates will preferably
be used.
Preferably, the hydrogenated sugar or the mixture of hydrogenated
sugars consists predominantly, i.e. to more than 50% by weight, of maltitol
(product of hydrogenation of maltose, a glucose dimer resulting from the
enzymatic hydrolysis of starch).
In another embodiment, component (a) may contain up to 75% by
weight of one or more reducing sugars, in addition to the hydrogenated
sugar(s). The insulating products based on mineral wool obtained with a
sizing composition having a certain content of reducing sugars are relatively
more coloured, but may have a real economic interest associated with the
low cost of reducing sugars or of mixtures of incompletely hydrogenated
sugars.
The content of hydrogenated sugars of the saccharide (component
(a)) is preferably at least equal to 30% by weight, in particular at least equal
to 50% by weight and ideally at least equal to 70% by weight.
The reducing sugars encompass oses (monosaccharides) and osides
(disaccharides, oligosaccharides and polysaccharides).
As examples of monosaccharides, mention may be made of those
comprising from 3 to 8 carbon atoms, preferably aldoses and advantageously
aldoses containing 5 to 7 carbon atoms. The aldoses that are particularly
preferred are the natural aldoses (belonging to the D series), especially
hexoses such as glucose, mannose and galactose.
Lactose or maltose are examples of disaccharides that may be used
as reducing sugar.
The polysaccharides that may be used for the present invention
preferably have a weight-average molar mass of less than 100 000,
preferably less than 50 000 and advantageously less than 10 000.
Preferably, the polysaccharide contains at least one unit chosen from
the abovementioned aldoses, advantageously glucose. Reducing
polysaccharides which consist predominantly (to more than 50% by weight)
of glucose units are particularly preferred.
The reducing sugar may especially be a mixture of monosaccharides,
oligosaccharides and polysaccharides, especially a dextrin.
Dextrins are compounds corresponding to the general formula
(C6H10O5)n. They are obtained by partial hydrolysis of starch. Their DE is
advantageously between 5 and 99 and preferably between 10 and 80.
Component (a), namely the saccharide consisting of hydrogenated
sugars optionally mixed with reducing sugars, advantageously represents
from 30% to 70% by weight and preferably from 40% to 60% by weight of
solids of the sizing composition.
Component (b) is a monomeric polycarboxylic acid. It may be a
dicarboxylic, tricarboxylic or tetracarboxylic acid.
The dicarboxylic acids include, for example, oxalic acid, malonic acid,
succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic
acid, sebacic acid, malic acid, tartaric acid, tartronic acid, aspartic acid,
glutamic acid, fumaric acid, itaconic acid, maleic acid, traumatic acid,
camphoric acid, phthalic acid and derivatives thereof, especially containing at
least one boron or chlorine atom, tetrahydrophthalic acid and derivatives
thereof, especially containing at least one chlorine atom such as chlorendic
acid, isophthalic acid, terephthalic acid, mesaconic acid and citraconic acid;
The tricarboxylic acids include, for example, citric acid, tricarballylic
acid, 1,2,4-butanetricarboxylic acid, aconitic acid, hemimellitic acid, trimellitic
acid and trimesic acid;
Examples of tetracarboxylic acids that may be mentioned include
1,2,3,4-butanetetracarboxylic acid and pyromellitic acid.
Citric acid will preferably be used.
Component (b), namely the monomeric polycarboxylic acid,
advantageously represents from 30% to 70% by weight and preferably from
40% to 60% by weight of solids of sizing composition of the present
invention.
The weight ratio of component (a) to component (b) is preferably
between 70/30 and 30/70 and in particular between 60/40 and 40/60.
As explained in the introduction, the presence of a high concentration
of an epoxysilane is an essential technical characteristic of the present
invention.
The sizing composition of the present invention advantageously
contains from 2.1% to 7% by weight, preferably from 2.3% to 6% by weight,
in particular from 2.5% to 5% by weight and ideally from 3% to 4.5% by
weight of at least one epoxysilane, these percentages being expressed
relative to the sum of components (a) and (b).
The higher the content of epoxysilanes, the more appreciable the anti-
ageing effect. The relatively high cost of epoxysilanes leads, however, to
limiting the amounts of epoxysilanes used.
It is, however, probable that the increase in the cost price of the sizing
composition, resulting from the use of high concentrations of an epoxysilane,
is compensated for by the possibility of using less sizing composition.
The epoxysilanes of the present invention may be trialkoxysilanes or
dialkoxysilanes, i.e. they may comprise two or three alkoxy functions that
may be hydrolyzed to silanol functions. Trialkoxysilanes are particularly
preferred.
The alkoxy groups are advantageously methoxy or ethoxy groups,
methoxy groups, which are more reactive than ethoxy groups, being
preferred.
The epoxysilane used in the present invention to improve the ageing
resistance of insulating products based on mineral wool bound by binders
based on hydrogenated sugars is advantageously chosen from the group
formed by 3-glycidyloxypropyl-trialkoxysilanes, 3-glycidoxypropyl-dialkoxy-
alkylsilanes, epoxycyclohexylethyltrialkoxy-silanes and epoxycyclohexylethyl-
dialkoxyalkyl-silanes.
The 3-glycidyloxypropyl-trialkoxysilanes are particularly advantageous
and, among these, the Applicant has obtained excellent results with
(3-glycidyloxypropyl)trimethoxysilane, sold, for example, under the name
GLYMO by the company Evonik, under the name Z-6040 by the company
Dow Corning or under the reference OFS-6040 by the company Xiameter.
The sizing composition may also comprise a catalyst which may be
chosen from Lewis bases and Lewis acids, such as clays, colloidal or non-
colloidal silica, organic amines, quaternary ammoniums, metal oxides, metal
sulfates, metal chlorides, urea sulfates, urea chlorides and silicate-based
catalysts.
The catalyst may also be a compound containing phosphorus, for
example an alkali metal hypophosphite, an alkali metal phosphate, an alkali
metal polyphosphate, an alkali metal hydrogen phosphate, a phosphoric acid
or an alkylphosphonic acid. Preferably, the alkali metal is sodium or
potassium.
The catalyst may also be a compound containing fluorine and boron,
for example, tetrafluoroboric acid or a salt of this acid, especially a
tetrafluoroborate of an alkali metal such as sodium or potassium, a
tetrafluoroborate of an alkaline-earth metal such as calcium or magnesium, a
zinc tetrafluoroborate and an ammonium tetrafluoroborate.
Preferably, the catalyst is sodium hypophosphite, sodium phosphite or
a mixture of these compounds.
The amount of catalyst introduced into the sizing composition
generally represents not more than 20% by weight and advantageously from
1% to 10% by weight relative to the total weight of components (a) and (b).
The sizing composition in accordance with the invention may also
comprise the conventional additives below in the following propoprtions
calculated on the basis of 100 parts by weight of component (a) + (b) :
from 0 to 40 parts and preferably from 4 to 25 parts of an oil or oil
emulsion,
from 0 to 5 parts of a hydrophobic agent, in particular a silicone,
from 0 to 20 parts of a polyol other than the hydrogenated sugars,
from 0 to 30 parts and preferably 0 to 20 parts of urea,
from 0 to 30 parts of an extender chosen from lignin derivatives such
as ammonium lignosulfonate (ALS) or sodium lignosulfonate, and animal or
plant proteins.
The role of the additives is known and briefly recalled:
The oils are anti-dust agents and hydrophobic agents; urea acts as a
plasticizer and also makes it possible to adjust the gel time of the sizing
composition so as to avoid pregelation problems; the extender is an organic
filler that is soluble or dispersible in the sizing composition, which makes it
possible especially to reduce the cost thereof.
The hydrophobic agent is preferably a reactive silicone, i.e. a
polydiorganosiloxane bearing at least one hydroxyl (silanol), carboxyl,
anhydride, amine, epoxy or vinyl function capable of reacting with at least
one of the constituents of the sizing composition and/or with the silanol
groups of the surface of glass.
The reactive silicone is preferably liquid at room temperature. Its
average molar mass is generally less than or equal to 50 000 and preferably
less than or equal to 10 000.
Preferably, the reactive silicone comprises a reactive function,
advantageously a silanol function, at each of its chain ends.
The reactive function of the reactive silicone may be blocked with a
protecting group that releases the said reactive function under the effect of
heat. The proportion of reactive silicone in the sizing composition generally
ranges from 0.1 to 5 parts, preferably from 0.3 to 3 parts, advantageously
from 0.5 to 2.5 parts and better still from 0.7 to 1.8 parts by weight per
100 parts by weight of the sum of components (a) and (b).
The preparation of the sizing composition is performed by simple
mixing of the abovementioned constituents with water.
The sizing composition is intended to be applied to mineral fibres,
especially glass or rock fibres.
A subject of the present invention is also a process for manufacturing
an insulating product based on mineral wool, comprising
- the application of an aqueous sizing composition as described above
to mineral wool fibres, and
- the evaporation of the solvent phase of the aqueous sizing
composition and thermal setting of the non-volatile residue of the
composition.
Conventionally, the sizing composition is projected by spraying onto
the mineral fibres at the outlet of the centrifugal device and before they are
collected on the receiving member in the form of a lap of fibres which is then
treated at a temperature allowing the crosslinking of the sizing and the
formation of an unmeltable binder. The crosslinking of the sizing according to
the invention takes place at a temperature comparable to that of a standard
phenol-formaldehyde resin, at a temperature of greater than or equal to
110°C, preferably greater than or equal to 130°, and advantageously greater
than or equal to 140°C.
The high reactivity of the epoxysilane prevents the preparation of a
sizing composition a long time in advance. In a preferred embodiment, the
process of the present invention consequently comprises a step of preparing
the aqueous sizing composition, less than 24 hours, preferably less than 4
hours, in particular less than 1 hour and ideally less than 15 minutes before
the step of application to the fibres, the epoxysilane preferably being mixed
with the aqueous sizing composition containing all the other ingredients.
The sizing composition advantageously has a pH of between 2 and 4,
in particular between 2.5 and 3.5 and ideally close to 3.
The acoustic and/or heat insulating products obtained via the process
according to the invention from these sized fibres also constitute a subject of
the present invention.
These products are generally in the form of a mattress or felt of glass
or rock mineral wool, or alternatively a web of mineral fibres, also glass or
rock fibres, intended especially for forming a surface coating of the said
mattress or of the said felt. When component (a) contains a very small
proportion of reducing sugars, the products have a particularly advantageous
white colour.
In addition, the insulating products have great resistance to the
development of microorganisms, especially moulds, which is due to the non-
fermentable nature of the hydrogenated sugars.
In this specification where reference has been made to patent
specifications, other external documents, or other sources of information, this
is generally for the purpose of providing a context for discussing the features
of the invention. Unless specifically stated otherwise, reference to such
external documents is not to be construed as an admission that such
documents, or such sources of information, in any jurisdiction, are prior art, or
form part of the common general knowledge in the art.
Example 1
Binder based on hydrogenated sugars
Sizing compositions comprising the constituents given in Table 1,
expressed in parts by weight, are prepared.
The sizing compositions are prepared by introducing, into a container,
water (about 80% of the final composition), the hydrogenated sugar (maltitol
syrup), citric acid, sodium hypophosphite (catalyst), the anti-dust oil
emulsion, the silicone emulsion and, finally, the epoxysilane (or the
comparative aminosilane) with vigorous stirring until the constituents have
fully dissolved.
The glass wool is manufactured by the technique of internal
centrifugation in which the molten glass composition is transformed into
fibres by means of a tool known as a “centrifugation plate”, comprising a
basket forming a chamber for receiving the molten composition and a
peripheral strip pierced with a multitude of orifices: the plate is driven in
rotation about its axis of symmetry arranged vertically, the composition is
ejected through the orifices under the effect of the centrifugal force and the
material escaping from the orifices is drawn into fibres with the assistance of
a stream of drawing gas.
Conventionally, a sizing spraying crown is arranged below the fibre-
drawing plate so as to regularly distribute the sizing composition over the
glass wool that has just been formed.
The mineral wool thus sized is collected on a conveyor belt equipped
with internal suction plenums which retain the mineral wool in the form of a
felt or a lap at the surface of the conveyor. The conveyor then circulates in an
oven maintained at 270°C where the sizing constituents polymerize to form a
binder. The insulating product obtained has a nominal density equal to 17.5
kg/m , a nominal thickness of about 75 mm and a loss on ignition of the order
of 5%.
The properties of the sizing compositions given in Table 1 below are
evaluated in comparison with a standard sizing composition containing a
phenol-formaldehyde resin and urea (Reference) prepared in accordance
with Example 2, test 1 of WO 01/96254 A1.
The tensile strength is measured according to standard ASTM C 686-
71T on a sample cut out by stamping from the insulating product. The sample
is in the form of a ring 122 mm long, 46 mm wide, a radius of curvature of the
cut of the outer edge equal to 38 mm and a radius of curvature of the cut of
the inner edge equal to 12.5 mm.
The sample is placed between two cylindrical mandrels of a testing
machine, one of which is mobile and moves at a constant speed. The
breaking force F of the sample is measured and the tensile strength TS,
defined by the ratio of the breaking force F (in newtons) to the mass of the
sample (in grams), is calculated.
The tensile strength is measured immediately after manufacture (initial
tensile strength) and after accelerated ageing in an autoclave at a
temperature of 105°C at 100% relative humidity for 15 minutes.
The “regain in thickness” indicates the compressive elastic modulus of
the final product. To measure it, a compression pressure is applied, for a
given time, such that the thickness is reduced to 1/4.8 of its initial value. After
releasing this compression pressure, the thickness is again measured. The
regain in thickness is the ratio of the measured thickness after release of the
compression pressure to the initial thickness.

*according to the invention
It may be seen that the tensile strength of sample 4 prepared in
accordance with the invention has a tensile strength before ageing equivalent
to that of the reference sample, whereas all the comparative samples (Nos.
1–3) have tensile strengths before ageing which are at least 10% less than
those of the reference sample.
Moreover, the loss of tensile strength after ageing is significantly lower
for the sample according to the invention than for the three comparative
samples.
These results show that the use of a high concentration of an
epoxysilane (3% of GLYMO) makes it possible to significantly reduce the loss
of tensile strength of an insulating product prepared with a binder based
solely on hydrogenated sugars.
The value of the regain in thickness does not appear to depend on the
concentration of the epoxysilane.
Example 2
Binder based on hydrogenated sugars and reducing sugars
The process is performed in the manner described in Example 1, but
using, as saccharide, a mixture of a hydrogenated sugar (maltitol syrup) and
of a reducing sugar (glucose syrup). Table 2 specifies the weight fractions of
the sizing compositions used and the mechanical properties of the mineral
wool samples obtained.

*according to the invention
It is found that the tensile strength of the samples prepared in
accordance with the invention (Nos. 11 and 12) is better both before ageing
and after ageing, in comparison with samples containing less epoxysilane
(Nos. 9 and 10), but also in comparison with samples containing an
equivalent amount of an aminosilane (Nos. 7 and 8).
As already stated in Example 1, the regain in thickness values for the
final products appear to be independent of the chemical nature and
concentration of the silane.
