Sizing composition for mineral wool comprising a saccharide, an organic polycarboxylic acid and a reactive silicone, and insulating products obtained Full description Background of the invention Thermal and/or acoustic insulation products cal) The invention relates Fabric, specifically glass wool, which is based on mineral wool, acoustic insulating products, formaldehyde (CH,0), or rock and formaldehyde-free organic binder capable of sizing composition. The invention relates more specifically to the composition of a glue, ° organic binder to form the organic crosslinking material on at least one crosslinking; the said polycarboxylic acid saccharide; It contains at least one molar mass of 0001 saccharide having at least one organic carboxylic acid molar mass; Insulating products and insulation products 0 The process of manufacturing insulation products based on mineral wool generally includes the manufacturing stage itself, as it can be carried out by various processes; For example, according to the inner or outer wool. Centrifugal sorting that includes several nozzles 01 of the device under a small peripheral wall; The material is sent towards the peripheral wall 5 filaments and exits from it in the form of centrifugal force fibers, the effect of the centrifugal sorting force, and when it exits the centrifugal sorting device; The fibers are pulled and carried towards a receiving member v with a high temperature and speed; gas stream via a gas stream receiving member fibers (mineral wool). ; Thermal hardening is carried out on fibers by “projection” coming out of the ily device to provide a glue composition that includes a centrifugal coated material and the receiving member. The coated fiber network is subjected to 0 m; thermal and/or acoustic insulating product tensile dimensional stability especially; Specifically, stability in terms of dimension and color, compression after compression, thickness recovery, strength V + homogeneous color, and the composition of the glue to be projected onto the mineral wool is generally provided in the form of a solution such as cadditives and thermosetting additives. Aqueous resin comprising an adhesion-promoting resin to cross-link the resin; Silane material that enhances adhesion, catalyst, catalyst, and the like. It is generally applied “dust-preventing mineral oil Cu) csilane Yo spraying. The properties of the glue composition depend largely on the properties of the resin. It is from a good point of view and to have sprayability of application; It is necessary for the glue composition to show the ability to spray on the surface of the fibers to bind them effectively. A deposite is able to be deposited.

7 The resin should be stable for a certain period of time before it is used to form the dil composition as the composition is generally prepared at the time of use by mixing the resin and the above additives.

At the regulatory level it is necessary to consider the resin to be non-polluting ¢ This means that it contains - and generates during the gluing stage or later - Hv a possible amount of compounds that may be harmful to human health or environment.

The most commonly used thermosetting resins are Resol 68015:. In addition to Alle belonging to phenolic resins, these resins del have good cross-linkability at the mentioned thermal conditions “affinity for mineral fibers soluble in water; It has a high affinity for mineral fibers and is relatively inexpensive. formaldehyde phenol (CsHsOH)”; With a molar ratio of formaldehyde/|phenol greater than 6) to enhance the interaction between phenol and formaldehyde and to reduce the level of residual phenol in the resin. The condensation reaction takes place between the phenol monomers, with a degree of condensation and formaldehyde, while a degree of condensation of 0 is determined, which is relatively insoluble in water. It reduces the ability of long chains to avoid the formation of long chains, and accordingly; The resin includes a certain percentage of dilutability inactive monomer, namely formaldehyde; Its presence is undesirable because of its known harmful cunreacted monomer effects. (COMNH2)) Urea-based resins for sale and for this reason.” Vo is treated by seizing it in the form of free formaldehyde, which reacts with free formaldehyde. curea nonvolatile urea Certain economic formaldehyde as a result of its low cost because it can be introduced in a relatively large amount without affecting the mechanical properties of the resin work efficiency; Specifically, without damaging the mechanical properties 0 of the final product, which significantly reduces the total cost of the resin. Despite this, it was noted that; In the temperature conditions to which the network is exposed to obtain the cross-linking of the resin, “urea-formaldehyde condensation products are not stable;” (CONH,),) and urea (CH,0) formaldehyde decompose and decompose Where it is released ammonia (NH;) and in turn decomposes at least partially to obtain ammonia Yo in the plant.

environmental regulations are compelled; which has become constrained by the “Sl” degree, manufacturers of insulation products are looking for solutions that can further reduce levels of unwanted emissions; Specifically, formaldehyde. Solutions that are replaced by resol compounds in sizing pall compositions © are known and based on the use of a carboxylic acid polymer, specifically an acrylic acid polymer.
