Definitions
- the present invention relates to the field of fibre-based sheet materials and more particularly to a glass mat that can be used as a substrate for the production of products coated, covered or impregnated with bitumen, especially for roofing and/or damp-proofing applications.
- bituminous membranes that are applied to the surface to be roofed or damp-proofed. These membranes generally consist of a substrate in the form of a sheet coated or impregnated with a bituminous matrix.
- Sheet materials may be of various types and are usually obtained from organic or mineral fibres, preferably in the form of nonwovens.
- Glass mats can be obtained by any technique known per se, in particular the so-called wet technique described especially in the reference work “The Manufacturing Technology of Continuous Glass Fibres” by K. L. Loewenstein, Publ. Elsevier, 2nd edition, 1983, pp. 315-317.
- This technique which is similar to papermaking techniques, consists in preparing an aqueous suspension of chopped glass fibres, in depositing this suspension as a film on a filter belt to which suction is applied in order to-remove some of the water from the film deposited, in applying a binder composition to the wet film, in drying the mat and crosslinking the binder in an oven, and then packaging the mat in the desired manner.
- the final product is in the form of quite a thin sheet (with a thickness of about 0.2. to 0.8 mm) and generally packaged in rolls.
- the binder is often an aqueous composition based on a urea-formaldehyde resin, this resin having a satisfactory temperature withstand at the temperatures used subsequently for the bitumen impregnation.
- glass mats have the drawback of having a relatively low tear strength, which detracts from the ease of use and especially forces the user to take precautions when handling it for making up the membrane or for laying it on a roof.
- the object of the invention is to provide a glass-based material with an improved tear strength, without its manufacture being more complicated than that of a conventional mat.
- EP-A-0 763 505 describes a glass fibre mat for the manufacture of asphalt roof shingles, the strength of which is improved thanks to a urea-formaldehyde binder modified by a self-crosslinkable vinyl additive.
- a minor proportion of fibres may not consist of glass, and may especially be chosen from organic fibres such as nylon, polyester, polyethylene and polypropylene fibres. That document provides no specific information about these organic fibres and contains no particular example illustrating this possibility.
- the present invention is based on the discovery that many organic fibres are not suitable for the manufacture of a mat and even have a very negative effect on the properties of the mat in bituminous roofing applications, but this drawback may be overcome by very carefully selecting the synthetic materials.
- the subject of the invention is a fibre-based mat that can be used for making up bituminous membranes, comprising glass fibres and organic fibres bound together by a binder, characterized in that the fibres have a shrinkage at 130° C. of less than or equal to 5%.
- ⁇ glass mat>> or ⁇ glass veil>> encompasses according to the invention materials well known from the person skilled in the art of glass fibre-based products. These are thin sheet-like materials, of an essentially isotropic structure, that is to say that there is no preferred orientation of the fibres.
- the organic fibres used in the mat manufacture have a high melting point in order to prevent them from degrading during the thermal steps in the manufacture of the mat, especially oven drying and crosslinking, and in the use of the mat, particularly when in contact with the bituminous binder.
- the synthetic organic material is chosen to have a melting point above about 220° C.
- the fibres are selected according to their thermal shrinkage: this parameter corresponds to the dimensional variation, in this case the shortening, of the fibre after it has been exposed to a given temperature for a defined time.
- this parameter corresponds to the dimensional variation, in this case the shortening, of the fibre after it has been exposed to a given temperature for a defined time.
- the initial length Li of the fibre before heating and then the final length Lf are measured, the shrinkage r being equal to
- the key shrinkages according to the invention are expressed for a temperature of 130°°C., produced in an atmosphere of vapour, and for a time of 30 minutes.
- the shrinkage is chosen to be less than or equal to 5%, preferably less than or equal to 4% and particularly less than or equal to 3%, for example about 2 to 3%.
- this fibre quality may be obtained using semicrystalline polymer materials, particularly those in which the spinning process allows them to undergo drawing which increases the degree of crystallinity.
- Other manufacturing conditions such as presence of nucleation agents or the temperature factor may also lead to the organisation of the base macromolecules so that the polymer of initial amorphous structure starts to adopt a crystalline structure and to turn semi-crystalline.
- Fibres satisfying the requirements of the invention may be found among polyester fibres, especially polyalkylene terephthalate and particularly polyethylene terephthalate fibres.
- Organic fibres suitable for wet processes for manufacturing nonwovens are preferred, these fibres containing a sizing composition allowing the individual filaments to be dispersed in water.
- the organic fibres may have variable dimensions, with a mean diameter of about 7 to 25 ⁇ m for a linear density of about 0.5 to 2 dtex.
- the fibres are advantageously chopped to a length of the order of one millimetre to a few tens of millimetres, especially 6 to 30 mm.
- the effect of the organic fibres is clearly perceptible above 5% by weight with respect to the total weight of fibres.
- the proportion of organic fibres is advantageously about 5 to 30%, especially 20 to 30% and particularly about 25% by weight with respect to the total weight of fibres.
- the glass fibres used according to the invention are of a type conventional for the production of mat, preferably in the form of chopped yarns, having a length of the order of ten millimetres, especially 6 to 30 mm and preferably about 10 to 20 mm, for example 12 to 18 mm. It should be understood that a certain proportion of yarns (for example 5 to 10%) may be chopped to a length of up to 100 mm. Moreover, continuous yarn, especially glass yarn, may be introduced into the mat as reinforcement in the machine direction.
- the binder used to form the mat is advantageously based on a urea-formaldehyde resin, preferably one which is modified by vinyl and/or acrylic additives in the manner known especially from U.S. Pat. No. 4,681,802 and EP-A-0 763 505.
- the amount of binder corresponds to generally a solids content of from 15 to 30% by weight with respect to the mat.
- the mat is manufactured with a grammage, usual for glass mats, of about 30 to 150 g/m 2 , particularly 50 to 120 g/m 2 .
- the amount of material in the mat according to the invention for a given grammage is slightly greater than that contained in a glass mat, which means that the thickness is relatively greater and/or the porosity is less.
- the porosity is about 1500 to 1900 l/m 2 .s for a 50 g/m 2 mat.
- the subject of the invention is also a bituminous membrane comprising a substrate coated, covered or impregnated with a bituminous matrix, characterized in that the substrate is a mat as described above.
- the bituminous matrix may be chosen from matrices known per se: natural, modified or unmodified bitumen, or a synthetic binder such as a “light-coloured binder” making it possible in particular to give the membrane a decorative colour.
- aqueous suspension of fibres is prepared, in which the fibres comprise:
- the fibre suspension which also contains the usual additives, namely antifoam, dispersant, viscosity modifier, etc., is processed under standard conditions on a mat manufacturing machine comprising (i) a hydroformer on which a partially dewatered wet film is formed, (ii) a station for applying the binder by spraying, coating [a curtain coater] or passing through a bath containing an aqueous composition based on a urea-formaldehyde resin plasticized by an acetate and an acrylic, which deposits on the mat an amount of binder corresponding to a solids content of 19% by weight with respect to the weight of mat, and (iii) a drying and crosslinking oven having several temperature zones from 135 to 215° C. through which the mat runs with an average residence time of about 30 seconds, preferably slightly less than 30 seconds.
- a drying and crosslinking oven having several temperature zones from 135 to 215° C. through which the mat runs with an average residence time of about 30 seconds, preferably slightly less
- the mat poses no problem in manufacture and is obtained with a grammage of 50 g/m2, a thickness of 0.3 mm and a porosity of 1580 l/m 2 .s.
- test pieces in the machine direction and 10 test pieces in the cross direction were cut in widths of 50 mm and lengths of 250 mm from the mat specimen.
- Each test piece was fixed between the jaws of a tensile testing machine and the system for driving the movable clamp was actuated until the specimen broke: the values of the tensile strength (in newtons) and of the elongation at break (as a percentage of the nominal length) were then measured. Also taken was a measurement of the tensile strength at 250° C. under a fixed load equal to 10% of the strength value measured previously, and the time required for the test piece to break was measured.
- test pieces in the machine direction and 10 test pieces in the cross direction were cut in widths of 50 mm and lengths of 100 mm from the mat specimen. A sharp cut was made on each test piece starting from the edge of a short side and parallel to the long sides halfway between the long sides, and 50 mm in length.
- the distance between the jaws of a tensile testing machine was set to be equal to 50 mm, the test piece was fixed in the jaws and the tensile tester was actuated, setting the pull rate at 100 mm/min.
- the maximum load (in N) when the test piece completely split into two parts was recorded. The tear strength was expressed as the average of the ten measurements.
- Example 1 had very satisfactory mechanical properties and dimensional stability. It was processed on a continuous bituminous-membrane manufacturing line by impregnation with hot bitumen at about 200° C., having a good amenability to impregnation, even giving the membrane a very attractive appearance.
- a mat was manufactured in the manner indicated in Example 1, but exclusively based on glass yarn.
- the mat had a grammage of 50 g/m 2 , a binder content corresponding to a 24% solids content by weight with respect to the weight of mat, a thickness of 0.3 mm and a porosity of 2000 l/m 2 .s. It was subjected to the same mechanical tests as the mat of Example 1.
- Example 1 was repeated with an organic fibre that does not meet the criteria of the invention. It was a polyester fibre sold by Tergal Fibres under the reference “1.6 dtex T110 mi-mat coupé” [1.6 dtex T110 chopped half-mat], which is also water-dispersible, characterized by a linear density of 1.6 dtex, a chop length of 12 mm, a shrinkage at 130° C. in a steam atmosphere of 7%.
- 1.6 dtex T110 mi-mat coupé [1.6 dtex T110 chopped half-mat]
- this mat has a low mechanical strength, less than that of the conventional glass mat. In particular, it may be seen that the anisotropy of the mat is greatly increased. Furthermore, the mechanical strength at 250° C. is non-existent.
