Definitions
- the present invention relates to water-repellent aqueous emulsions, in particular for water-repellency of constructions and building materials of the stone, concrete, mortar, terracotta (bricks, tiles, etc.), wood, as well as process for preparing the emulsion and a waterproofing process.
- Humidity is the source of damage in constructions: frost fragments, appearance of mosses and lichens, loss of thermal insulation, etc. This is why compositions have been developed for waterproofing construction materials.
- Water repellents in the aqueous phase are more difficult to produce.
- the difficulties are in particular to give them an efficiency close to that in the solvent phase and also sufficient stability over time.
- Patent application WO 97/47569 proposes, for water-repellency of materials such as wood, cellulose materials, masonry and concrete, an aqueous emulsion comprising: (1) at least one resin, comprising at least one T or Q unit , of average formula (I)
- R 1 - R 2 , R 3 , R 4 - R 5 , and R 6 are alkyl radicals, R is a hydrogen atom or an alkyl radical; - the symbols a, b, c and d represent the ratio of the silicon atoms of type M, D, T respectively; and Q with respect to the total number of silicon atoms of the resin of average formula (I)
- One of the main objectives of the invention is the development of more stable aqueous emulsions when they are applied to materials, which means that the silicone resin within the droplets of the emulsion is not released immediately on contact. of the material and thus, there is no phenomenon of repulsion of the material with respect to the successive layers applied to said emulsion.
- higher stability is particularly observed when applied to materials with an alkaline surface (eg mortar, cement mortar).
- Another objective of the invention is to provide aqueous emulsions having improved applicability, that is to say a reinforced wettability which results in a more homogeneous distribution.
- Another objective of the invention is to provide aqueous emulsions having an increased imbibition speed (or capillarity coefficient), that is to say the active principles contained in the droplets of the emulsion penetrate more quickly and easily in applied materials.
- the present invention therefore relates to an aqueous emulsion, optionally in the form of a microemulsion, comprising:
- At least one resin comprising at least one T or Q unit, of average formula (II):
- R 1 - R 2 , R 3 , R 4 - R5, and R 6 are alkyl, alkenyl, aminoalkyl, aryl, arylalkyl, alkylaryl or araryl radicals,
- - R is a hydrogen atom or an alkyl radical
- the symbols a, b, c and d represent the ratio of the silicon atoms of type M, D, T respectively; and Q relative to the total number of silicon atoms of the resin of average formula (II); and the symbol e represents the number of groups ⁇ Si (Oy 2 R) relative to the total number of silicon atoms of the resin of average formula (II) .; these symbols varying in the following intervals:
- - (2b) at least one carboxylic acid or anhydride containing from 3 to 22 atoms; - (2c) optional, at least one crosslinking agent which is a water-soluble metal.
- polyoxyalkylenated polyethoxyethylenated, polyoxypropylenated, polyoxybutylenated alkylphenols in which the alkyl substituent is CQ-C-
- alkoxylated terpene hydrocarbons such as ethoxylated and / or propoxylated ⁇ - or ⁇ -pinenes, containing from 1 to 30 oxyethylene and / or oxypropylene units;
- ethoxylated tristyrylphenols such as Soprophor BSU and Soprophor S40 marketed by Rhodia Chimie.
- anionic surfactants chosen from:
- alkyl ester sulfonates of formula R-CH (S ⁇ 3M) -COOR ' where R represents a C8- 20 0- preferably C-
- 'Alkylbenzenesulfonates are C9-C20.
- alkyldimethylbetaines alkylamidopropyldimethylbetaines, alkyltrimethylsulfobetaines, condensation products of fatty acids and protein hydrolysates, (ii) alkylamphoacetates or alkylamphodiacetates in which the alkyl group contains from 6 to 20 carbon atoms.
- Examples of commercial surfactant products (3) (c) include MIRANOL C32, MIRANOL C2M from Rhodia Chimie (cocoamphoacetate), ALKATERIC 2CIB, CB, PB.CAB and LAB products from Rhodia Chimie .
- the surfactant (3) is chosen from those of the class of nonionic surfactants. More particularly in this case, very good results are obtained with a nonionic surfactant chosen from polyoxyalkylenated C8-C22 aliphatic alcohols containing from 1 to 25 oxyalkylene units; and preferably oxyethylene units and / or oxypropylene units According to another preferred variant of the emulsion according to the invention, this is developed without the use of crosslinking agent. This method of preparation is also particularly suitable when the surfactant (3) is non-ionic.
- each of the radicals R ⁇ to R ⁇ of the resin can be a linear or branched alkyl radical, for example methyl, ethyl, propyl, butyl, isobutyl; an alkenyl radical, for example vinyl; an aryl radical, for example phenyl or naphthyl; an arylalkyl radical such as for example benzyl or phenylethyl, alkylaryl such as for example tolyl, xylyl; or an araryl radical such as biphenylyl.
- the patterns M of the resin of formula (II), when there are several, can be identical or different between them; the same remark also applies to patterns D and T.
- the patterns (O1 / 2R) can be identical or different between them.
- the resin is a copolymer of formula (II) where:
- each represents an alkyl radical, linear or branched, C-pC ⁇ ;
- - R represents a hydrogen atom or a linear or branched alkyl radical, C-
- the copolymer has in its structure at least one T unit, associated with at least one of the units chosen from M and D.
- H species A represents the copolymers M D T (O1 / 2R) (IV) where:
- the A1 species is such that:
- R 1 to R6 are identical or different alkyl radicals in C-pC- ⁇ ; .
- R is a hydrogen atom or a C1-C4 alkyl radical;
- - c is between 0.4 and 0.8;
- the species A2 is such that: - R 1 to R ⁇ are identical alkyl radicals in C1-C3;
- R is a hydrogen atom or C1-C4 alkyl radical
- - c is between 0.4 and 0.8;
- H species B represents the copolymers DT (O 1 2 R) (V) where:
- species B1 is such that:
- R 4 to R 6 identical or different from each other, each represents an alkyl radical, linear or branched, C ⁇ -C ⁇ ;
- - R is a hydrogen atom or a linear or branched alkyl radical, C-
- R 4 to R> represent an alkyl radical, linear or branched, C3-C8;
- - b is between 0.2 and 0.9
- - c is between 0.1 and 0.8 - e is between 0.2 and 1.5.
- species B2 is such that:

- R is a hydrogen atom or preferably a linear C-1-C3 alkyl
- - b is between 0.2 and 0.6
