Definitions
- the invention relates to the use in a formulation of adhesives for floors.
- an aqueous dispersion based on a functional polymer having a glass transition temperature below 0 ° C. and in particular a polymer carrying a ureido function does not release during the application of volatile organic compounds, an aqueous dispersion based on a functional polymer having a glass transition temperature below 0 ° C. and in particular a polymer carrying a ureido function.
- the adhesives for floors according to the invention can be used to fix various coverings such as carpets, PVC tiles on a floor made in particular of concrete, plaster.
- adhesives for floors are obtained by the formulation of an aqueous dispersion of polymer, tackifying resins solubilized in solvents or plasticizers, mineral fillers, a wetting agent, an antifoam and water. .
- Such a composition gives off volatile organic compounds (VOCs) which can come either from the aqueous dispersion, or from the solvents which serve to dissolve the tackifying resins or from the tackifying resins themselves.
- VOCs volatile organic compounds
- the problem that the invention intends to solve is the development of an aqueous dispersion with a low VOC content ( ⁇ 1000 ppm) which is a very efficient binder for the formulation of adhesives for soil with a low VOC content, ie is to say
- WO9521884 describes adhesive formulations composed of an aqueous dispersion containing a polymer, and fillers not requiring the use of organic solvents, plasticizers or tackifying resins.
- the polymer of the aqueous dispersion is characterized by a glass transition temperature (Tg) of less than -30 ° C and of molar masses by weight greater than 20,000.
- US 5,196,468 describes adhesive formulations containing less than 2% of organic compounds having a boiling point below 100 ° C., comprising an acrylic latex, a tackifying resin, a plasticizer of the monophenyl polyethylene or polypropylene glycol type and fillers.
- the Applicant has found that the use, in an adhesive formulation, of a dispersion containing a polymer bearing particular functional monomers such as ureido monomers, leads, after application, to the formation of a crosslinked film having improved properties compared to that an uncrosslinked film.
- the first object of the present invention is the use in a formulation of adhesives for soil of an aqueous dispersion containing from 20 to 70% by weight of at least one polymer P1 containing: from 50 to 99.5% by weight of at least one (meth) acrylic ester A, from 0.1 to 5% by weight of at least one carboxyic acid B, from 0 to 20% by weight of at least one unsaturated nitrile C , from 0 to 30% by weight of at least one vinyl monomer D, and from 0.5 to 5% by weight of at least one monomer carrying a ureido E function.
- the (meth) acrylic esters A are chosen from the group containing methyl methacrylate, methyl acrylate, butyl acrylate and 2-ethyl hexyl acrylate
- the unsaturated acids B are chosen from the group containing acrylic acid, methacrylic acid and itaconic acid.
- the unsaturated nitriles C are chosen from acrylonitrile and its derivatives.
- the vinyl monomers D are chosen from the group containing vinyl acetate, vinyl laurate, vinyl versatates.
- the functional monomers E are monomers capable of creating interactions between themselves or the acid monomers possibly present. These are monomers carrying ureido function chosen from the group containing in particular ethylimidazoiidone (meth) acrylate, ethylimidazolidone (meth) acrylamide. And 1 - (2 - ((2-hydroxy-3- ( 2-propenyloxy) -propyl) amino) ethyl) - 2-imidazolidone.
- the polymer P1 has a glass transition temperature below 0 ° C and preferably between 0 ° C and -30 ° C and more preferably between -15 ° C and -30 ° C.
- the aqueous dispersion is obtained by emulsion polymerization of a mixture of monomers containing:
- the polymer is prepared by a batch or preferably semi-continuous process of radical emulsion polymerization, which may use a seed polymer or create the seed in situ.
- the monomers are introduced into the reactor at a speed such that they are consumed as they are introduced and that the heat released by the polymerization reaction can be removed.
- the functional monomer (s) can be introduced continuously during the whole polymerization process or in a sequenced manner.
- the 20 preferred introduction is to introduce the functional monomer either at the beginning or at the end of the polymerization so that the final polymer consists of macromolecular chains carrying functional monomers and non-functionalized macromolecular chains. It is a means of modifying the distribution of the crosslinking nodes in the material and of optimizing the distribution
- the monomers are polymerized at temperatures between 30 and 95 ° C in the presence of water-soluble initiators.
- the preferred water-soluble initiation systems are ammonium, sodium and potassium persulfates, water-soluble azo derivatives such as 4,4'-azobis-4-cyanovaleric acid or 2,2'-azobis-2-amidinopropane dihydrochloride.
- water-soluble azo derivatives such as 4,4'-azobis-4-cyanovaleric acid or 2,2'-azobis-2-amidinopropane dihydrochloride.
- redox systems such as H 2 O 2 , tert-butyl hydroperoxide or the sodium salt of the mixture of m- and p-diisopropyl benzene hydroperoxide used in the presence of reducing agents such as for example sodium formaldehyde sulfoxylate, sodium metabisulfite or ascorbic acid.
- the molecular weights of polymers P1 are optimized thanks to the initiation system, at the polymerization temperature.
- transfer agents such as dodecylmercaptan, terdodecylmercaptan or mercaptopropionic acid for example may be useful.
- the surfactants used are most often a mixture of anionic and nonionic surfactants chosen, for example, from alkyl sulfates, alkyl ether sulfates, alkyl aryl ether sulfates, sulfonates of alkyl, alkyl aryl sulfonates, diphenyl alkyl ether sulfonates, ethoxylated fatty alcohols, ethoxylated alkyl aryls, etc.
- the final dry extract of these aqueous dispersions is between 20 and 70% and preferably between 40 and 65%.
- aqueous dispersions can then be formulated in formulations containing no solvent, therefore they will lead to sol adhesives without VOC having properties equivalent to those containing solvents.
- These dispersions can, in addition, be formulated in the presence of resins containing rosin or derivatives of rosin such as rosin esters or hydrogenated rosin for example.
- a post-polymerization step is carried out with the initiator solution 2 and the activator solution 2.
- Example 1-b The latex obtained according to this example is produced in the same way as in test 1-a, only the composition of the preemulsion of monomers changes.
- a post-polymerization step is carried out with the initiator solution 2 and the activator solution 2.
- the latex obtained according to this example is produced in the same way as in test I-c, only the order of introduction of the preemulsion 1 and of the preemulsion 2 was reversed.
- the latex is poured into a beaker.
- the final viscosity of the product is adjusted between 20,000 and 60,000 mPas using a thickener of the polyacrylate type.
- the floor covering test pieces are placed in the cylinder 48 hours before the tests so as to obtain a curved test piece (simulation of a floor covering roll).
- the adhesive is deposited on an AGLOPLAN type plate using a notched trowel (deposit of approximately 350 g / m2).
- the floor covering samples are applied to the adhesive at regular time intervals (every 5 min) then pressed with the mass of 2 kg for 10 s.
- the mass is then removed and it is observed whether the edges of the specimen are raised or not. If the test tube is then raised, the mass is again applied for 10 s. and one continues thus until obtaining a non-raising of the edges. The time from which the test pieces remain in contact with the support and no longer rise is noted.
- test pieces of floor covering are applied every 5 min in the same way as above up to 60 minutes.
- the bondings thus made are stabilized for 24 hours before evaluation. This evaluation is carried out manually by removing the support samples, thereby determining the maximum time during which the adhesive has retained sufficient adhesive power to bond the floor covering.
