Definitions

  • the present invention relates to the use of phosphonates / phosphinates in aqueous formulations as carriers for improving the absorption of the compounds present in said formulations, into porous wettable materials, such as paper, wood, masonite and plaster.
  • the present invention relates to the use of low molecular weight phosphonates and/or phosphinates, soluble in aqueous formulations in order to improve impregnation capacity as shown by the substantial absence of any blooming phenomena.
  • the present invention relates to the use of phosphonates and/or phosphinates in the application of aqueous solutions onto ligneous materials.
  • compositions comprising phosphonates and phosphinates for applications onto substrates of plant origin are known in the art.
  • US patent 6,423,251 describes a composition for ligneous materials which may be in solid, aqueous or aqueous emulsion form, based on the condensation products between urea and boron oxyacids, and optionally containing carbonization catalytic agents (carbonization auxiliaries).
  • Said catalytic agents may be acidic compounds such as boric, sulphuric or phosphoric acids, and salts thereof.
  • other phosphorous compounds are indicated as being suitable for use as "carbonization auxiliaries” such as for example, phosphoric acid salts with nitrogen containing compounds and organo-phosphor compounds such as for example phosphoric esters.
  • Such phosphorus compounds contain three aliphatic C 6 -C 20 chains within the molecule, and hence possess high molecular weights. Furthermore, said phosphinates/phosphonates are insoluble in water, but are emulsionable. In the examples, the use of such compositions for spraying wheat fields inoculated with a pathogenic fungus is described. Hence the patent does not refer to applications onto wood.
  • WO 9304585 describes a herbicidal composition which comprises a phosphonate or phosphinate.
  • R 2 is oxyalkyl
  • the compounds of formula (I) which may be cited are diethylethylphosphonate, dimethylmethylphosphonate and cyclic phosphonates.
  • the quantities of the compounds of formula (I) in the aqueous formulations varies, as a percentage by weight over the total, from 0.1 % to 15%, preferably from 1% to 10%, even more preferably from 1% to 8%.
  • aqueous formulations of the invention is achieved through the impregnation of said substrates while operating within a temperature interval of from 5°C to 80°C, preferably at a temperature of less than 40°C.
  • Application may be performed using even simple impregnation methods, such as for example application by spraying, by roller or by brushing.
  • aqueous formulations containing compounds of formula (I) allow the carrying of both ionic and non-ionic additives, and also polymeric additives, such as for example urea formaldehyde condensates, into porous substrates. Furthermore, the presence of solvents and surfactants is not required in the formulations.
  • the additives which may be carried using the compounds of formula (I) are for example the following:
  • additives which may be carried using the compounds of formula (I) include the following: colorants, pigments, gelling agents, waxes, proteins, surfactants, silanes, siloxanes, cellulose, halogens, additives for improving the mechanical or aesthetic characteristics of porous items such as for example vinyl latexes.
  • aqueous formulations are in the form of aqueous solutions or dispersions, preferably aqueous solutions.
  • aqueous dispersions preferably emulsions are used if it is possible to obtain them with the components of the formulation.
  • compositions of the present invention include:
  • the percentage by weight of the various components is in reference to the total weight of the composition; with the total sum of the components present being equal to 100%.
  • the percentage dry weight of the aqueous compositions according to the present invention is from 3% a 50%, preferably from 10% to 40%.
  • condensation products belonging to a) such as neutral polyethylene oxide phosphates, neutral phosphates of oligomeric alcohols, condensation products between melamine, urea formaldehyde and phosphoric acid described in USP 3.832.316 ; or the condensation product between formaldehyde, urea, dicyandiamide and phosphoric acid described in USP 3.887.511 .
  • the condensate may be obtained through the reaction of the above indicated substances using the following amounts:
  • aqueous formulations of the invention may also have high dry content, generally even greater than 40%, preferably even up to 50% by weight of the formulation.
  • aqueous formulations marketed for applications to the above mentioned porous supports leave unabsorbed residues, and that it is possible to avoid such drawbacks by the addition of the compounds of formula (I). This way the unabsorbed residues are made to completely penetrate the porous material without leaving any deposits.
  • the presence of compounds of formula (I) in the aqueous compositions containing the additives to be carried allows the improvement of absorption, even when the additive would only be partially absorbed or not absorbed into the porous substrate as it is.
  • compositions onto porous materials are simple and may even be performed using conventional impregnation methods such as for example by immersion at atmospheric pressure or by using repeated cycles including depressurisation, immersion and pressurisation stages.
  • the composition is applied onto the surface to be treated by using, as already mentioned, techniques such as application by brushing, by roller or by spraying, which are simpler and less costly than those indicated above.
  • the ligneous material treated with the composition of the present invention shows essentially no blooming due to the surface crystallisation of salts.
  • dry components have been calculated as % by weight of all components, excluding water, over the composition total.
  • a white pine board having dimensions 80 x 15.5 cm and a thickness of 2 cm was impregnated by brushing using 1,000 g/m 2 of composition on average.
  • Example 1a was repeated but with the use of the composition of example 2. Following application of the composition and evaporation of the aqueous solvent, the presence of evident quantities of solid residues was observed on the surface of the wood.
  • Example 1a was repeated but with the use of the composition of example 3.
