Definitions
- Epoxy adhesive composition comprising elastomer nanoparticles, and uses thereof
- the invention relates to the field of storage facilities for liquefied gas comprising a sealed and thermally insulating tank, with membranes.
- the invention relates to the field of sealed and thermally insulating tanks for the storage and/or transport of liquefied gas at low temperature, such as tanks for the transport of Liquefied Petroleum Gas (also called LPG) having for example a temperature between -50°C and 0°C, or for the transport of Liquefied Natural Gas (LNG) at around -162°C at atmospheric pressure.
- LPG Liquefied Petroleum Gas
- LNG Liquefied Natural Gas
- the present invention relates in particular to epoxy adhesive compositions comprising nanoparticles with an elastomer core at a low glass transition temperature, their method of preparation, and their uses, in particular at low temperature.
- Epoxy resins are widely used as coatings, adhesives, insulating materials and matrices for composite fibers due to their stiffness, high temperature performance, chemical resistance and adhesive properties.
- the currently most widely used technique consists in introducing a low molar mass elastomer, miscible in the reactants corresponding to the epoxy resin to be reinforced.
- the most widely used reactive elastomer is a 1,4-butadiene- stat-1,2-butadiene-stat-acrylonitrile terminated at each end by a COOH function, designated by CTBN.
- CTBN does not make it possible to effectively reinforce certain epoxy resins whose molar mass between crosslinking points is too low, in particular resins of the DGEBA type, since the improvement in hardness is accompanied by a loss of resistance.
- the resins reinforced by the techniques of the prior art are used for the adhesion of thermal insulation to the hull of the tanks of LNG carriers, but these resins do not have sufficient mechanical strength characteristics, in particular of the type tensile and shear strength when the outside temperature is very low, typically in an arctic ocean type environment, so as to resist the pressure of the liquefied gas moving in the vessel.
- the object of the invention is to allow the preparation of a mastic which avoids the aforementioned drawbacks and which has mechanical characteristics of the tensile (detachment) and shear resistance type, when hot (about 20° C. at approximately 40° C.) and when cold (for example from approximately -25° C. to -60° C.) improved, these characteristics allowing it in particular to be used as a putty for restoring the flatness and adhesion of the elements of thermal insulation on the tanks of LNG carriers or ships using LNG (Liquefied Natural Gas) as fuel, or for all other low temperature applications.
- LNG Liquefied Natural Gas
- Another object of the invention is to provide a solution which does not or very little modify the thixotropy of the epoxy adhesive to be reinforced, that is to say which allows a direct and identical transposition of the means implementation of state-of-the-art bonding.
- the mastic thus presents, thanks to the use of core-shell nanoparticles with an elastomer core at a low glass transition temperature, associated with a particular epoxy resin, according to the invention as defined below, and this, surprisingly, particularly advantageous mechanical characteristics of resistance to traction and to hot and cold shearing, allowing it thus to be used as an adhesive for insulation material for LNG carriers or ships using LNG as fuel.
- the thixotropy of the epoxy adhesive thus reinforced is unchanged.
- the invention relates to a composition suitable as an epoxy adhesive composition
- a composition suitable as an epoxy adhesive composition comprising: a) a first part composition comprising: a1) at least one epoxy resin or a mixture of epoxy resins chosen from the group consisting of bisphenol A diglycidyl ether, optionally brominated, and its oligomers, bisphenol F diglycidyl ether, optionally brominated, and its oligomers, diethylene glycol epoxy and its oligomers, as well as combinations thereof; a2) a reactive diluent chosen from diglycidyl ethers of C4-C12 aliphatic diols; a3) core-shell type nanoparticles, the core comprising or consisting of at least one elastomer having a glass transition temperature (Tg) comprised in a range ranging from -40 to -110°C, preferably between - 70 and -110°C, the shell comprising or being made of an epoxy resin compatibilizer; a4) at least one fill
- the combination of core-shell type nanoparticles and at least one filler having a low coefficient of thermal contraction makes it possible to obtain a polymerized material whose coefficient of thermal contraction, also called coefficient of thermal expansion or coefficient of thermal expansion, either as low as possible and so that the variation in volume occupied by the material as a function of temperature is as low as possible.
- diglycidyl can also be understood as diglycidyl.
