Definitions
- the invention relates to a grafted thermosetting thermoplastic polyurethane (TPU), pure or mixed, which has the advantage of self-crosslinking in the presence of water or not, only under high temperature conditions (at least above 85 ° C. , advantageously greater than 90 ° C.) and in the absence of a catalyst. It also relates to pure polyurethane or the ⁇ nodurci mixture after self-crosslinking of said thermosetting TPU.
- TPU thermosetting thermoplastic polyurethane
- thermoplastic materials are used for the development of certain products such as hot fluid transport tubes, electric cables, solid wheels, seals, silent blocks, shoe soles, etc.
- Thermoplastic polyurethanes are used in these different applications, in particular for their ease of implementation and their exceptional quality at room temperature, their flexibility and their mechanical resistance.
- these materials have the disadvantage of being not very resistant to heat so that the products obtained from these materials, depending on their use, have a short lifespan when used in an atmosphere with a temperature relatively high.
- thermosetting polyurethane resins if they are actually intended to resist heat, remain very difficult to shape, so that their use is limited.
- the objective has therefore been to develop polyurethanes having the physical characteristics and the ease of transformation of thermoplastic polyurethanes and the characteristics thermomechanics of thermosetting polyurethanes, and in particular their temperature resistance.
- thermoset finished product it was necessary to make the TPU crosslinkable so that they can be further processed, that is to say shaped, then only then, crosslinked to obtain a thermoset finished product.
- the Applicant has proposed in document FR-A-2 794 759 to graft hydrolyzed organosilanes on thermoplastic polyurethanes using a diisocyanate acting as a bridging agent between the polymer chain and the organosilane.
- This bridging agent also makes it possible to attach the aminosilane and prevents it from breaking the main chains of the polyurethane.
- This material in the form of granules cannot be stored for a long time, cannot be easily handled by the final transformer because it cannot be transported by suction and wait for its implementation in the open air, without being dried at the last moment as all commercially available thermoplastic polyurethanes.
- the final drying crosslinks the polyurethane in its granulated form and does not allow its thermoplastic transformation.
- it is especially important not to transform the grafted polyurethane diisocyanate without drying it because a tiny presence of water would cause crosslinking, which would lead to mechanical breakages of great importance during the transformation.
- the grafted TPU proposed by the invention solves all of these problems. More specifically, the invention relates to a thermosetting thermoplastic polyurethane grafted, pure or as a mixture, capable of being obtained by direct grafting onto a pure thermoplastic polyurethane or as a mixture, of a crosslinking agent chosen from the group comprising trimers of suitable diisocyanates. initiating the crosslinking reaction at a temperature above 85 ° C and blocked isocyanates, solid or liquid, whose release point is above 85 ° C
- pure or mixed TPU means a TPU alone or in mixture with at least one thermoplastic polymer chosen from the group comprising, without limitation, the
- PE polyethylene
- PP polypropylene
- thermosetting polyurethane is new with regard to the state of the art known to the Applicant, not only by its structure (limited number of constituents and specific crosslinking agent), but also by its behavior.
- the Applicant has in fact found that, quite surprisingly, the selection of the crosslinking agent, in the absence of silane, avoids the triggering of a crosslinking phenomenon at room temperature despite the presence of water and it was necessary, to initiate crosslinking, to increase the temperature to around at least 85 ° C, or up to a temperature above the drying temperature (80 ° C), in the absence of a catalyst.
- thermoplastic polyurethane after grafting, was only reduced by a factor of 1.5 instead of 2 when the polyurethane is grafted with a diisocyanate, which makes it possible to widen the working range.
- the MVR of the material is further reduced by a factor of 2, which improves the rheology of the polymer in the extrude ⁇ se and calibrators, and reduces the formation of rotassures during injection into molds.
- the grafted polyurethane has a behavior closer to that of polyethylenes than standard thermoplastic polyurethanes.
- the Applicant has observed that the crosslinking bonds have a much higher temperature resistance than the bonds obtained with the diisocyanates used alone or in the presence of silanes. This characteristic makes it possible, in the event of a mixture of TPU with other polymers, not to break the crosslinking bonds, and therefore not to lose the mechanical, thermal and chemical characteristics of the mixture during final processing, at elevated temperatures above 180 ° C.
- the blocking molecule is any molecule usually used (caprolactam, oxime, etc.) and perfectly known to those skilled in the art, in particular molecules. described in the publications: .Wicks Prog. Org. Coat. 9, p3, 1981 and L.TLPhai et al Makromol. Chem. 186, 1189, 1984.
- the crosslinking agent is a trimer of IPDI and represents between 1 and 6% by mass of the polyurethane grafted alone or as a mixture.
- the grafted TPU of the invention is in the form of granules which can be stored in the state and subsequently transformed directly by the transformer by extrusion, calendering, injection, etc., and as already said, at temperatures high above 180 ° C due to the choice of crosslinking agent.
- the TPU is grafted then transformed directly continuously so as to obtain profiles of determined shape.
- the invention also relates to the process for manufacturing the grafted polyurethane previously described, which consists in reacting, at a temperature of at least 85 ° C., a thermoplastic polyurethane, pure or in mixture, with one of the crosslinking agents previously described, advantageously a trimer of IPDI, then recovering the grafted thermosetting thermoplastic polyurethane obtained.
- the invention also relates to the thermoset polyurethane capable of being obtained after self-crosslinking of the thermosetting thermoplastic polyurethane graft previously described.
- Material 58447 witness: viscosity measured on melt indexer at 210 ° C under 8.16 kg 40.
- the viscosity of the material constituting the test piece is no longer measurable by the indexing melt
- the Kofler melting point goes from 185 ° C for the controls to 240 ° C for the material of the test piece
- estane 58315 ether type Estane 58315 ether type, Hardness 85 Shore A, Kofler Fusion around 150 ° C
- a mixture of 58315 with 4 pcr of Vestanat was carried out in a single screw extruder of the same type as that of Example 1, to obtain granules of 58315 grafted. After storage for one month, the grafted granule was dried in a ventilated oven at 80 ° C for two hours, then transformed on a calender at 190 ° C to obtain a sheet 1 millimeter thick. The same calendering operation was carried out with the control 58315.
- test pieces were cut to carry out a "hot set test" specific to the cable manufacturer. In an oven at 200 ° C, the material is subjected to a stress of 0.2 MPA. The test piece broke before two minutes. The crosslinked test piece has passed the 15-minute limit.
