Definitions
- the invention relates to glass strands coated with a sizing composition intended for reinforcing organic materials of the polymer type. It also relates to the sizing composition used to coat said yarns, the composites incorporating these yarns and the use of sized yarns for the manufacture of articles by molding.
- the glass strands used for reinforcement in general are produced industrially from molten glass streaks flowing from the multiple orifices of a die. These threads are drawn mechanically in the form of continuous filaments, then are gathered into basic threads which are then collected, for example by winding on a rotating support. Before their gathering, the filaments are coated with a sizing composition by passing over a suitable device such as coating rollers.
- the sizing composition is essential for several reasons.
- the sizing composition protects the glass filaments from abrasion which occurs when the latter rub at high speed on the various members serving to guide and collect them. It also establishes connections between the filaments which makes it possible to give cohesion to the thread.
- the yarn being made more intact, its handling, especially during weaving operations, is improved and untimely breaks are avoided.
- the sizing composition promotes wetting and impregnation of the glass strands by the matrix to be reinforced, which matrix is generally implemented in the form of a more or less fluid resin. The mechanical properties of the final composite are therefore significantly improved.
- the materials to be reinforced can integrate glass strands in different forms: continuous or cut strands, mats of continuous or cut strands, fabrics ...
- Composites which incorporate cut glass strands can be obtained, inter alia, by the “contact molding” technique which consists in coating the interior of an open mold, without counter mold, with resin to be reinforced and glass wires of variable length.
- the resin and the cut wires are sprayed together on the internal walls of the mold by means of a “gun” comprising an incorporated cutter capable of cutting the wires extracted from one or more windings, generally in the form of rovings, and a device for spraying the resin, supplied for example by a pneumatic pump.
- thermosetting polymers belonging to the family of polyesters or epoxides The quality of the composites obtained by this process largely depends on the properties provided by the glass strands, and therefore on the size which covers them. In particular, it is sought to obtain compositions giving a size which can be easily wetted or impregnated on the surface with the resin in order to ensure close contact between the wires and the resin and thus obtain the expected mechanical reinforcement properties. It is also desired that these compositions are compatible with rapid processing, in particular that the son / resin mixture which is sprayed onto the mold in the form of overlapping strips can spread evenly.
- the subsequent rolling step intended to eliminate air bubbles and to ensure a better distribution of the wires in the resin must also be of short duration. Furthermore, it is necessary for the sizing composition to have a certain “incompatibility” with the resin so as to prevent the son / resin mixture from forming a compact mass which “collapses” by simple gravity. The impregnation of the wire with the resin must nevertheless be fast enough so that the wire / resin mixture can have a satisfactory "conformability", that is to say that it is able to perfectly match the shape of the mold.
- the sizing composition coating the glass strands combines at least one bis-silane and at least one unsaturated monosilane chosen from vinylsilanes and (meth) acrylosilanes.
- the present invention therefore aims to provide a sizing composition for reinforcing wires, in particular intended for open mold molding, and more particularly for molding by simultaneous projection of glass and resin wires, which allow to have a rapid resin impregnation of the strands and improved cutting ability with limited flock production.
- the subject of the invention is glass strands coated with an aqueous composition which combines as tackifying film-forming agents at least one polyester, at least one polyvinyl acetate and at least one polyurethane.
- glass strands coated with a sizing composition glass strands "which have been coated with a sizing composition which comprises ", that is to say not only the glass strands coated with the composition in question as obtained at the immediate exit from the sizing member or bodies, but also these same strands after they have undergone one or more other treatments.
- son means the basic son from the gathering under the die of a multitude of filaments, and products derived from these son, including the assemblies of these basic son rovings.
- Such assemblies can be obtained by simultaneously unwinding several windings of basic wires, then by assembling them into wicks which are wound on a rotating support. It can also be “direct” rovings with a title (or linear density) equivalent to that of the assembled rovings, obtained by gathering filaments directly under the die, and winding on a rotating support.
- the term "aqueous sizing composition” means a sizing composition in the form of a solution in which the liquid phase consists of 97% by weight of water, preferably 99% and better still 100%, the remainder consisting, where appropriate, of one or more essentially organic solvents which can help to dissolve certain constituents of the sizing composition.
