- the mass Mn of the polyether sequences is between 100 and 6000 and preferably between 200 and 3000.
- polymers with polyamide blocks and polyether blocks whether from the copolycondensation of previously prepared polyamide and polyether blocks or from a one-step reaction, have, for example, an intrinsic viscosity of between 0.8 and 2.5 measured in metacresol. at 25 ° C for an initial concentration of 0.8 g / 100 ml.
- the polyamide block and polyether block copolymers may be prepared by any means for hanging the polyamide blocks and the polyether blocks.
- essentially two methods are used, one said in two steps, the other in one step.
- the polyamide blocks are first produced and then, in a second step, the polyamide blocks and the polyether blocks are bonded.
- the polyamide precursors, the chain limiter and the polyether are mixed; we then obtain a polymer having essentially polyether blocks, polyamide blocks of very variable length, but also the various reagents reacted randomly which are distributed randomly (statistically) along the polymer chain. Whether in one or two steps it is advantageous to operate in the presence of a catalyst.
- Usual polymers those with PA blocks in PA 6, in PA 12 in PA 6 / 6.6 and those in PTMG blocks.
- the other of the substrates may be of the same nature, that is to say polyether block copolymer or of different nature.
- polymers and copolymers such as polyolefins, polyamines, polyamides, polyesters, polyethers, polyesterethers, polyimides, polyamidemides, polycarbonates and resins.
- phenolic, crosslinked or uncrosslinked polyurethanes in particular foams, polyimides, poly (ethylene vinyl acetate), natural or synthetic elastomers such as polybutadienes, polyisoprenes, styrene-butadiene-styrene (SBS), styrene- butadiene-acrylonitrile (SBN), polyacrylonitriles, natural or synthetic fabrics, in particular organic polymeric fiber fabrics such as polypropylene fiber, polyethylene, polyester, polyvinyl alcohol, polyvinyl acetate, polyvinyl chloride, polyaramid, fiberglass and carbon fiber fabrics, as well as materials such as leather, paper and cardboard. All these materials can also be in the form of foam, where possible.
- laminates By way of example of laminates, mention may be made of: polyamide block copolymer and polyether blocks / adhesive / TPU polyamide block copolymer and polyether blocks / adhesive / polyamide block copolymer leather and polyether blocks / adhesive / polyurethane polyamide block copolymer foam and polyether blocks / adhesive / TPU foam block copolymer polyamide and polyether blocks / adhesive / rubber block copolymer polyamide and polyether blocks / adhesive / nonwoven polyolefin
- the substrates generally have a thickness of 0.4 to 5 mm.
- the present invention further relates to a method of manufacturing the laminate described above which comprises the steps of:
- the humid atmosphere is preferably air at a relative humidity
- the method also comprises, prior to step a) defined above, a step of cleaning the surfaces of the substrates to be bonded with at least one organic solvent such as methyl ethyl ketone (MEK), acetone and ethyl acetate.
- MEK methyl ethyl ketone
- the presses used in the process of the invention are the conventional presses in the field of laminate manufacture.
- Pebax 55-1 and Pebax 70-1 denote polyamide block and polyether block copolymers. They consist of alternating blocks of PA 12 and PTMG.
- the method of making the comparative laminates is as follows:
- the surfaces of the substrates to be bonded at room temperature are cleaned; - Brush is applied a layer of primer on the cleaned surfaces;
- the primer layer is dried
- a two-component adhesive is applied by brush to the primer layer
- the adhesive layer is dried
- the primer layer has a dry thickness of 1 to 4 ⁇ m and the adhesive layer has a dry thickness of 30 to 50 ⁇ m.
- Comparative laminates C1, C'2 and C-2 were subjected to peel tests according to ISO 11339, speed 100 mm / minute, and the results are given in Table VI.
- Laminates according to the invention were produced by proceeding as follows: the surfaces to be glued of the two substrates with an organic solvent are cleaned at ambient temperature,
- the adhesive polymer material according to the invention is applied to only one of the surfaces to be bonded,
- the two substrates are docked; and pressurized, in air, for 1 minute at a pressure of 4 bar and at a temperature controlled to control creep, in this case a temperature of 20 to 120 ° C.
- the thickness of the layer of adhesive polymer material is from 150 to 150
- the laminates according to the invention No. 5 and 6 were subjected to peel tests as a function of time according to the ISO11339 standard, speed 100 mm / minute. The results of these tests are given in FIG. 1. An increase in the peel strength is noted when a terpolymer (ethylene / vinyl acetate / MAH) tackifier is added to the adhesive polymeric material.
- a terpolymer ethylene / vinyl acetate / MAH
