Abstract
Description
La présente invention concerne des compositions aptes à être utilisées comme agent d'expansion dans la fabrication des polymères thermoplastiques et/ou thermodurcissables. Elle a plus particulièrement pour objet des compositions comprenant du trans-1,2 dichloroéthylène ( TDCE ) et au moins un hydrofluoro-oléfine et leur utilisations. Dans le domaine des mousses thermoplastiques et thermodurcissables comme dans d'autres applications, le protocole de Montréal visant à limiter la dégradation de la couche d'ozone a imposé des règles strictes concernant l'utilisation de produits fluorés. Ces derniers sont caractérisés par leur ODP (Ozone Depletion Potential). Les CFC (chlorofluorocarbure) étaient la première génération de produits, les HCFC (hydrochlorofluorocarbure) la seconde, tous deux n'ont pas un ODP nul ou négligeable. C'est le cas de la troisième génération de produits, à savoir les HFC (hydrofluorocarbure). Ces produits sont d'ailleurs largement utilisés à ce jour dans le domaine des mousses. The present invention relates to compositions suitable for use as an expanding agent in the manufacture of thermoplastic and / or thermosetting polymers. More particularly, it relates to compositions comprising trans-1,2-dichloroethylene (TDCE) and at least one hydrofluoroolefin and their uses. In the field of thermoplastic and thermosetting foams as in other applications, the Montreal Protocol to limit the degradation of the ozone layer has imposed strict rules regarding the use of fluorinated products. These are characterized by their ODP (Ozone Depletion Potential). CFCs (chlorofluorocarbons) were the first generation of products, HCFCs (hydrochlorofluorocarbons) the second, both do not have zero or negligible ODPs. This is the case of the third generation of products, namely HFCs (hydrofluorocarbon). These products are also widely used to date in the field of foams.
La ratification du protocole de KYOTO sur la maîtrise des émissions de gaz à effet de serre génère une contrainte supplémentaire sur ces produits fluorés, à savoir un abaissement de leur GWP (Global Warming Potential) Ainsi, l'utilisation d'au moins un HFC comme agent d'expansion dans la fabrication des mousses à base d'isocyanates a été décrite dans le brevet EP 381986. Devant les contraintes environnementales de plus en plus sévères, le remplacement partiel de HFC dans la composition d'agent d'expansion a été suggéré. Le document WO 02/099006 divulgue une composition azéotropique de HFC et de trans 1,2-dichloroéthylène comme agent d'expansion dans la fabrication des mousses. The ratification of the KYOTO protocol on the control of greenhouse gas emissions generates an additional constraint on these fluorinated products, namely a lowering of their GWP (Global Warming Potential) Thus, the use of at least one HFC as blowing agent in the manufacture of isocyanate-based foams has been described in EP 381986. In view of the increasingly severe environmental constraints, the partial replacement of HFC in the blowing agent composition has been suggested. . WO 02/099006 discloses an azeotropic composition of HFC and trans 1,2-dichloroethylene as an expanding agent in the manufacture of foams.
L'objet de la présente invention vise à fournir une composition qui répond à la fois aux critères d'ODP négligeable et de bas GWP. La contribution à l'effet de serre d'un fluide est quantifiée par un critère, le GWP qui résume le pouvoir de réchauffement en prenant une valeur de référence de 1 pour le dioxyde de carbone. The object of the present invention is to provide a composition that meets both negligible ODP and low GWP criteria. The contribution to the greenhouse effect of a fluid is quantified by a criterion, the GWP which summarizes the heating power by taking a reference value of 1 for carbon dioxide.
Les méthodes de fabrication de mousses de polyuréthane ou de polyisocyanurate sont généralement connues et consistent en général à faire réagir un polyisocyanate organique (incluant le diisocyanate) avec un polyol ou un mélange de polyols en présence d'un agent d'expansion. Methods of making polyurethane or polyisocyanurate foams are generally known and generally involve reacting an organic polyisocyanate (including diisocyanate) with a polyol or a polyol blend in the presence of a blowing agent.
La réaction entre un polyisocyanate et un polyol ou un mélange de polyols peut être activée à l'aide d'une amine et/ou d'autres catalyseurs et des agents tensio-actifs. Dans beaucoup d'applications, les composants des mousses de polyuréthane ou polyisocyanurate sont des prémélanges. Plus généralement, la formulation des mousses est prémélangée en deux composants. Le premier composant, plus connu sous la dénomination composant A comprend la composition isocyanate ou polyisocyanate. Le deuxième composant, plus connu sous la dénomination composant B comprend le polyol ou le mélange de polyols, l'agent tensio-actif, le ou les catalyseur(s), le ou les agent(s) d'expansion. Le composant B pose des problèmes d'inflammabilité, même lorsque l'agent d'expansion entrant dans la composition du prémélange est non inflammable. The reaction between a polyisocyanate and a polyol or a mixture of polyols can be activated with an amine and / or other catalysts and surfactants. In many applications, the components of the polyurethane or polyisocyanurate foams are premixes. More generally, the formulation of the foams is premixed into two components. The first component, better known as component A, comprises the isocyanate or polyisocyanate composition. The second component, better known under the name component B comprises the polyol or the mixture of polyols, the surfactant, the catalyst (s), or the agent (s) of expansion. Component B poses flammability problems, even when the blowing agent used in the premix composition is non-flammable.
En outre, les problèmes d'élévation de pression des conteneurs renfermant le composant B sont souvent rencontrés lors de leur stockage. Un autre objet de la présente invention vise à fournir des compositions qui permettent de résoudre tout ou en partie les problèmes précités. La présente invention concerne des compositions comprenant du trans- 1,2 dichloroéthylène et d'au moins une hydrofluorooléfine non inflammable, de préférence ayant un nombre de carbone compris entre 3 et 5. On entend par liquide non inflammable un liquide dont le point éclair, mesuré selon la norme ASTM D3828, est supérieur à 55°C. L'inflammabilité ou non-inflammabilité d'un gaz peut-être déterminée dans les conditions définies dans la norme ASTM E681-01. Les tests d'inflammabilité des gaz sont conduits dans des conditions de température, de pression et de concentration en air conformes à la norme. Cette méthode de test est basée sur une source de chaleur électrique et sur l'observation de la propagation de la flamme. In addition, pressure elevation problems of containers containing component B are often encountered during storage. Another object of the present invention is to provide compositions that solve all or part of the aforementioned problems. The present invention relates to compositions comprising trans-1,2-dichloroethylene and at least one non-flammable hydrofluoroolefin, preferably having a carbon number of between 3 and 5. By non-flammable liquid is meant a liquid whose flash point, measured according to ASTM D3828, is greater than 55 ° C. The flammability or non-flammability of a gas may be determined under the conditions defined in ASTM E681-01. Gas flammability tests are conducted under conditions of temperature, pressure and air concentration in accordance with the standard. This test method is based on an electrical heat source and the observation of flame propagation.

Le 1,2,3,3,3-pentafluoropropène (HFO-1225 ye) étant gazeux, il est préalablement refroidi avant de réaliser le mélange avec le TDCE qui est également refroidi. Le HFO-1225 ye utilisé est un mélange d'isomère de conformation Z et d'isomère de conformation E avec une part majoritaire d'isomère Z. DCE pur Exemple 1 Il n'a pas été observé de point éclair dans la gamme de température comprise entre -20 et 52°C alors qu'avec le TDCE pur, un point éclair a été observé entre -14 et ù 5°C. Au-dessus de 52°C, les compositions selon l'exemple 1 commence à passer à l'état gazeux. -14°C à -5°C Pas de point éclair25 6 EXPERIMENTAL PART EXAMPLE 1 A composition (Example 1) comprising 100 parts by weight of TDCE and 20 parts by weight of HFO-1225ye is prepared, then the flash point is determined under standard conditions (ASTM D3828). Since 1,2,3,3,3-pentafluoropropene (HFO-1225 ye) is gaseous, it is previously cooled before mixing with TDCE, which is also cooled.

Le prémelange ne présente pas de point éclair dans la gamme de température comprise entre ù 30 à 61 °C dans les conditions standards ( norme ASTM D3828). On fabrique ensuite une mousse en faisant réagir ce prémélange avec 110 parties en poids de DESMODUR 44V70L ( isocyanate) en présence de 2,82 parties en poids d'un catalyseur DABCO K-15 ( solution sel organique ) et de 0,18 parties en poids d'un catalyseur POLYCAT 5 ( aamine tertiaire ) et de 1,5 parties en poids d'un tensio-actif TEGOSTAB B 8465 ( polyether-modifié polysiloxane ).

The premix has no flash point in the temperature range of 30 to 61 ° C under standard conditions (ASTM D3828). A foam is then made by reacting this premix with 110 parts by weight of DESMODUR 44V70L (isocyanate) in the presence of 2.82 parts by weight of a DABCO K-15 catalyst (organic salt solution) and 0.18 parts by weight of weight of a POLYCAT 5 catalyst (tertiary amine) and 1.5 parts by weight of a surfactant TEGOSTAB B 8465 (polyether-modified polysiloxane). The foam obtained has a density of less than 35 kg / m3 and has a closed cell level of 68%.
