Definitions
- the present invention relates to the field of substitutes for impregnated glass veils.
- the invention relates to unfilled sheet products obtained by the papermaking process, with a very high content of latex precipitated in the mass and containing cellulosic fibers and non-cellulosic fibers.
- Document GB-A-1588354 discloses a paper composition of this type, where the non-cellulosic fibers are short organic fibers, normally incapable of forming a paper sheet without the flocculation carried out with the latex.
- document EP-A-0006390 discloses a composition for loaded papers where the binder is essentially used to bind the filler.
- the object of the invention is to considerably increase the rate of latex which can be precipitated, while retaining the possibility of obtaining, directly by a simple passage on a paper machine, thermoplastic sheets having excellent mechanical properties.
- products in accordance with the invention comprising a totally unusual level of latex, which can reach for example 2/3 by weight of the product, could be produced on a paper machine, which was not not previously considered possible.
- the new products obtained are characterized by a very high level of breaking strength, both cold and hot.
- the product obtained also exhibits good foldability.
- latex is important in the implementation of the invention, certain latexes making it possible to obtain a better set of good properties: cold and hot breaking strength, resistance to delamination and good adhesion power with respect to PVC, dimensional stability, foldability characteristics, in particular.
- glass fibers of length between 3 and 12 mm, preferably 3 and 6 mm, and of diameter between 5 and 15 ⁇ m.
- the choice of a type of glass fiber determines the choice of the content of these fibers in the mixture. in a manner known to those skilled in the art.
- compositions used as well as the results of the tests are collated in Table 1 below. These examples are of course not limiting.
- the nature of the flocculants, their dose can vary according to the nature of the latex used, the material, and the contact time between the products; the total dose of flocculants will usually be between 5 and 50 parts by dry weight per 100 parts of latex.
- Table 1 and the operating mode below provide in particular on this subject the indications which will enable a person skilled in the art to adapt the technique according to the invention to a variation of these parameters.
- compositions described above with regard to Table I also have a property which it has been deemed desirable to improve, in particular for applications where the plastisol coating is carried out on one side, which makes it more problematic. obtaining a good flat from the final product.
- the dimensional stability in water (accelerated test after 8 minutes of immersion on a FENCHEL device) of such a product previously baked 2 minutes at 200 ° C is of the order of 0.20% (elongation crosswise) .
- a dimensional stability in water is obtained of less than 0.10% and a rolling shrinkage rate of less than 5%, which represents remarkable improvements.
- the nature of the flocculants, their dose, as well as the number and place of introduction. may vary depending on the nature of the latex used, the material, the contact time between the products; the total dose of flocculants, which itself depends on the nature of these flocculants (in particular molecular weight, ionicity, etc., of the flocculant), will be between 2 and 30 parts by weight, preferably 3 and 10, per 100 parts by weight of latex.
- stage 2 To combat the rolling of plastisol coated products on one side on the front, it is preferable to carry out a treatment of stage 2 on the back side.
- stage 2 treatments can be coating, impregnation, surfacing operations, aimed at depositing chemical components on the surface or at the core (by spraying, size-press. Coater with blades or rollers, etc.). These include the addition of latex or plasticizer by size- press.
- thermal and / or mechanical treatments such as smoothing or calendering cold or hot.
- the product will generally be deposited at a rate of 10 to 100 g / m 2 (wet state), ie 2 to 60 g / m 2 after drying (preferably 2 to 20 g / m 2 ) in the case of a treatment on one side. and 3 to 40 g / m 2 in the case of a treatment on both sides.
- compositions according to the invention which are of particular interest will also be found below.
- compositions, methods and results corresponding to Examples 6, 7 and 8 are collated in Tables V and VI below.
