Definitions
- the present invention relates mainly to a suspension of silica, precipitated at a small particle size and also relates to the application of this suspension as a filler for paper and in particular with a view to improving the print quality.
- certain silicas can be advantageously used in the manufacture of paper, either as a mass filler for common papers such as newsprint, or as a coating filler for special papers requiring a higher surface quality, such as by example papers for color inkjet printers.
- silicas can significantly improve one or more of the following properties: opacity, whiteness, density, porosity, mechanical properties, etc.
- Certain papers, called special papers, must also have a very high surface quality: This is the case, for example, for papers for color inkjet printers, which are required to allow high-definition color reproduction. This surface condition can then be obtained by coating (coating) the sheets of paper with silica-based coating baths.
- This silica powder is offered at a particle size of 3 ⁇ m for application as a mass filler to improve the retention of the paper.
- the present invention is for its part more particularly concerned with the improvement of the print quality at the paper level. Unexpectedly, it has been demonstrated that it was possible to improve the quality "of the printing paper, thanks to the presence in it of doped silica particles and significantly diminished size relative to the particles of conventional silica.
- a first aspect of the invention relates to a suspension of doped precipitated silica of small particle size.
- the present invention aims to apply this suspension as a mass charge in the paper and in particular to improve the printing qualities of the latter.
- the present invention therefore has for first object a suspension of precipitated silica, on the surface of which is bound chemically at least one metallic element at least divalent, characterized in that the silica particles have a median diameter in volume of less than 2 ⁇ m.
- sheets of paper comprising a silica in accordance with the present invention exhibit better ink retention compared with sheets incorporating a silica having a volume median diameter greater than
- the silica particles have a volume median diameter of less than 1 ⁇ m and in particular less than 0.8 ⁇ m.
- the volume median diameter (d50) is determined by laser diffraction according to standard NF X11 -666.
- the quantity of the at least divalent metallic element bonded to the surface of the silica can vary within wide limits.
- this metallic element is present at. the surface of the silica in an amount of 0.01 to 30% by weight, more preferably at a rate of 0.5 and 15% by weight, and in particular between 3 and 10% by weight, depending on the specific surface of the silica. .
- the percentages are expressed by weight of the metal considered, for example aluminum, relative to the weight of silica. Mention may more particularly be made, for example of the metallic elements which can be bonded to the surface of the silica, of the alkaline earths, such as for example calcium, magnesium, zinc, strontium and barium; titanium; zirconium; and aluminum. According to a preferred embodiment of the invention, the metallic element is aluminum.
- the claimed silica suspension preferably has a silica content varying from 4 to 50% by weight, preferably between 5 and 30% by weight, and more preferably between 8 and 20% by weight.
- silica has (in the dry state) a BET specific surface of between 50 and 700 m 2 / g, preferably between 50 and 250 m 2 / g, in particular between 100 and 200 nrvVg .
- the BET specific surface is determined according to the BRUNAUER-EM ET-TELLER method described in “The journal of the American Chemical Society” Vol. 60, page 309, February 1938 and corresponding to standard NFT 45007 (November 1987).
- the surface treatment of silica using an at least divalent metallic element can be carried out according to one of the methods described in patents EP 493,263, EP 762,992 or EP 762,993, the teaching of which is completely included here in reference title.
- acidifying agent a strong mineral acid such as sulfuric acid, nitric acid or hydrochloric acid, or an organic acid such as acetic acid, formic acid or carbonic acid.
- silicate any common form of silicates such as metasiiicates, disilicates and advantageously an alkali metal silicate, in particular sodium or potassium silicate.
- the silicate is usually used in the form of an aqueous solution which may have a silicate concentration, expressed as SiO 2 , of between 40 and 330 g / 1, for example between 60 and 300 g / 1, in particular between 60 and 250 g / 1.
- sulfuric acid is used as the acidifying agent
- sodium silicate as the silicate
- the surface treatment is generally carried out on the suspension of precipitated silica obtained at the end of precipitation and before filtration and / or after disintegration of the filter cake obtained after filtration, according to one of the protocols described in the aforementioned patents.
- the metallic elements are used in the form of one of their salts, organic or inorganic.
- halides and oxyhalides such as, for example, chlorides and oxychlorides; nitrates; phosphates; sulfates and oxysulfates.
- the metal salts are introduced into the silica suspension in the form of solutions, generally aqueous; these salts could also, of course, be introduced in solid form, their dissolution then occurring after being brought into contact with the dispersion of silica, j
- the metal salt solutions are introduced gradually into the silica suspensions, in one or more stages.
- a silica suspension is obtained.
- the volume median diameter of the silica particles in suspension is greater than 1 ⁇ m. It should therefore be adjusted to a value in accordance with the invention. This adjustment can be made using ultrasound.
- a silica suspension in accordance with the invention by suspending a precipitated silica powder, doped at the surface with at least one metallic element at least divalent as defined above and whose particles have a diameter median in volume greater than 1 ⁇ m. The size of the particles in suspension is then adjusted to a value in accordance with the invention, that is to say less than 2 ⁇ m.

- a sheet of paper recovered on a form puller is dried in an oven for at least 12 hours at 80 ° C. It is weighed, we obtain the weight P1.
- Sheets of paper are printed without any surface treatment. Inkjet printing is performed using an EPSON Stylus Photo EX printer. The quality of the ink is assessed according to 3 criteria:
- the median diameter (d50) in volume is determined by laser diffraction according to standard NF X11-666, using a Coulter LS 230® laser granulometer.
- the pulp chosen is a mixture of short fibers at 80% and long fibers at 20% with a refinement of 30 ° Shopper Riegler.
