Definitions
- the present invention relates to compositions of additives for controlling rheology and mechanical properties, which can be used in polymerizable compositions, sealants, paints or even adhesives. These compositions provide improved control of rheology, in particular they have a viscosity and a threshold stress which can be adjusted. They also provide a strengthening of the mechanical properties of the formulations containing them.
- the formulation of the compositions of the invention provides solutions for manufacturing objects by a three-dimensional (3D) printing process, and more particularly large objects which can take dimensions of several meters and thicknesses of several centimeters.
- the compositions of the invention allow good dissipation of exotherms generated during the polymerization of polymerizable formulations containing them.
- the mechanical properties of the formulations comprising these polymerized compositions are improved and the products obtained from polymerized formulations comprising the compositions of the invention have low shrinkage.
- the compositions of the invention also allow good control of the rheology of formulations of putties, paints or even adhesives, with small quantities of these compositions.
- the monomers which are used in polymerization in different application fields most often have a very low viscosity because they are most often low molecular weight compounds.
- Their threshold constraint is close to zero.
- the use of functional oligomers or the addition of polymers makes it possible to increase the viscosity but can be a source of other disadvantages and the threshold stress remains insufficient.
- compositions are sought whose flow is limited, or even non-existent, or controlled according to the areas of use.
- the exotherm generated during the polymerization of monomers must also be controlled to avoid potentially generated defects.
- compositions of polymerized monomers generally have insufficient mechanical properties.
- 3D printing is a technical field widely used in industry and leisure. This technology allows the preparation of individual objects based on a definition of the object in the form of a computer file giving the dimensional parameters of the object to be printed.
- additive manufacturing in English: “additive manufacturing” or AM
- a real object from a virtual object. It is based on cutting the 3D virtual object into thin 2D strips. These thin strips are deposited one by one by fixing them on the previous ones, which makes it possible to manufacture the real object.
- the fixing of the strips on each other is possible when for example the material constituting the object is a composition of monomers extruded through a guided nozzle for the manufacture of the object which is polymerized once deposited on the previous layer.
- WO21029945 uses a similar approach with the use of reactive oligomers in the form of acrylates.
- An alternative is described in WO21 183396 but assumes an additional step consisting of carrying out a pre-polymerization, this to increase the viscosity when used in a 3D printing process by the extrusion technique through a nozzle, but this adds an extra step. In these examples, despite increases in viscosity, threshold stresses remain low and material flow is still observed.
- the applicant has sought to improve the formulations, an example of which consists of monomers and initiator because the sole combination of these components does not allow the correct construction of an object by polymerization under irradiation or thermally due to viscosity and 'a threshold constraint that is too low. The shrinkage during polymerization is also too great and the objects have many appearance defects.
- the addition of block copolymers within these formulations makes it possible to improve the mechanical properties, which is known to those skilled in the art.
- the presence of block copolymers also makes a positive contribution to the rheology, which is also known to those skilled in the art.
- Diamides and in particular fatty acid diamides are widely used in the field of formulation as agents allowing rheology control.
- compositions of diamides, hydrogenated castor oil and a polyamide particular, either two by two, or all three sets are disclosed as rheology additives.
- the combination of block copolymer, diamides and/or triamides and hydrogenated castor oil in a polymerizable monomer formulation, i.e. in the presence of a polymerization initiator, is an example of a solution to technical problems. relating to control of rheology, mechanical properties and control of polymerization. In particular, very significant effects of increasing viscosity and threshold stress are observed even when using small quantities of the compositions of the invention.
- the combination of block copolymer, diamides and/or triamides and castor oil provides a surprising effect and makes it possible to limit the quantity of these additives while providing improvements in the mechanical properties of the products obtained and with exotherm during processing. polymerizations better controlled than in the absence of the combination of these three compounds.
- the combined use of block copolymers, amides and castor oil therefore provides a number of unexpected technical effects. (improved rheology, improved mechanical properties, limited exotherms and shrinkage).
- the applicant has found that the combination of small quantities of castor oil, diamide and/or triamide, and block copolymers provides a viscosity and a stress at the threshold suitable for with the needs generated in formulations of sealants and adhesives, paints, or 3D printing.
- the combined presence of block copolymer, amide and hydrogenated castor oil is necessary to maximize the effects on the rheology of formulations containing them, and the technical effect obtained is much greater than the combination of just two of these compounds .
- compositions of the invention formulated with monomers have good resistance to the bead of the formulation before polymerization and allow their placement on the previously polymerized layer without defects.
- the objects obtained using these compositions also have good mechanical properties.
- the combination of castor oil, diamide and/or triamide, and block copolymers within a composition comprising one or more monomers makes it possible to obtain a significant effect making it possible to resolve existing technical problems in applications requiring high viscosities or an adjustment of these viscosities, with sufficient threshold constraints, and this with small quantities of these compounds.
- the quantities of castor oil, diamide and/or triamide, and block copolymers can be variable and make it possible to finely adjust the rheological constraints linked to the formulation of sealants, adhesives, paints and during the manufacturing of objects by 3D printing, while providing advantages in shrinkage, exothermic control and mechanical properties.
- Fillers can be added to the compositions of the invention formulated with monomers while retaining the advantage of the combination of castor oil, diamide and/or triamide, and block copolymers.
- compositions of the invention can also be used with ingredients derived from natural materials such as vegetable oils or fibers, which these are monomers, block copolymers, diamides and/or triamides, castor oil, or fillers.
- natural materials such as vegetable oils or fibers, which these are monomers, block copolymers, diamides and/or triamides, castor oil, or fillers.
- fillers When fillers are present within the compositions of the invention, fillers resulting from the recycling of polymer materials, charged or not, such as composite materials can be included, which provides the compositions of the invention with a favorable carbon footprint and recyclability of materials at the end of their life.
