Definitions
- the present invention relates to a hot-melt adhesive composition
- a hot-melt adhesive composition comprising at least one polyolefin such as in particular a copolymer of ethylene and of alkyl (meth) acrylate, at least one copolymer of the copolyamide type, and at least one tackifying resin, this composition having improved thermal resistance.
- Glues or hot-melt adhesives are thermoplastic materials which are solid at room temperature and which, when heated (around 180 ° C), become more or less viscous liquids. These liquids are applied to a first substrate and then covered with a second surface. By cooling, an adhesion is obtained between the substrate and the second surface.
- the open time is the period during which the adhesive which has been applied to a substrate which is at room temperature remains tacky, that is to say the period of time during which the second surface can be applied and by cooling to obtain adhesion between the substrate and the second surface. After this open time period, it is no longer possible to obtain sufficient adhesion between the substrate and the second surface.
- HMA hot melt adhesives
- Hot-melt adhesives based on copolymers of EVA (copolymer of ethylene and vinyl acetate) or of ethylene and of alkyl (meth) acrylate, in mixture with at least one tackifying resin, and with a styrenic block copolymers, as described in particular in document WO 95/13332, are well known; however, they have temperature resistance under load most often limited to 60-80 ° C, which prohibits certain applications in areas such as: automotive, building, packaging, textile, wood veneer and high-end binding.
- US Pat. No. 5,506,296 describes hot melt adhesives with improved thermal resistance made up of components which can be crosslinked with moisture.
- This document describes a hot-melt adhesive composition based on an EVA and polyisocyanate copolymer, the EVA copolymer being a copolymer with a melt index at 190 ° C. under a load of 2.16 kg of between 100 and 1000 g / 10 min and comprising, relative to the weight of said copolymer: 1) 60 to 90% of ethylene, 2) 10 to 40% of vinyl acetate, 3) 5 to 20 meq OH of an unsaturated ethylenic termonomer carrying at least one primary hydroxyl function per mole, said composition containing substantially no free hydroxyl function.
- Patent application WO 02/28959 belonging to the applicant, describes a mixture comprising by weight, 1 to 100% of a (co) polyamide block graft copolymer consisting of a polyolefin trunk and on average at least a polyamide graft, and 99 to 0% of a flexible polyolefin with elastic modulus in bending of less than 150 MPa at 23 ° C and having a crystalline melting point between 60 ° C and 100 ° C.
- this mixture can be used as an adhesive in powder form on supports such as carpet or nonwoven, on a temperature press; however, it is a dusting process and the product is applied pure (without formulation with other additives); moreover, the characteristics of temperature resistance under load are not sought.
- US 4,791,164 describes a hot-melt adhesive composition comprising a mixture of at least one polyamide and a terpolymer of ethylene, methyl acrylate and maleic anhydride; however, these are not copolyamides.
- the Applicant has recently developed and described in patent application FR 02 02394, unpublished, a hot-melt adhesive composition comprising from 20 to 80% of a mixture composed of a (co) polyamide block graft copolymer consisting of a trunk.
- polystyrene resin in polyolefin and at least one graft in polyamide, and at least one polymer chosen from polyolefins and polyamides, from 80 to 20% of a mixture comprising at least one tackifying resin and optionally other additives; with improved thermal resistance; however, these are not mixtures of copolymers of the copolyamide type with at least one ethylene copolymer, but copolyamides grafted onto a trunk such as polyethylene.
- Patent application EP 388 716 describes a hot-melt adhesive comprising, in mixture 40 to 80% by weight of a propylene copolymer and of a momomer with a carboxylic group, 7.5 to 50% by weight of an ethylene copolymer and acrylic acid or its esters, a copolymer of ethylene and vinyl acetate and a copolyamide; this adhesive does not contain a tackifying resin and is not used for thermal resistance properties but for its compatibility with various substrates such as polypropylene, PVC, textile materials, or Aluminum, for producing composite materials multi-layered.
- the present invention relates to a hot-melt adhesive composition with improved temperature resistance, comprising 20 to 50% by weight of a mixture of at least one polyolefin (A), and at least one copolymer (B) of the copolyamide type, and 50 to 80% by weight of a mixture of at least one tackifying resin (C) and optionally at least one component chosen from waxes, plasticizers, mineral fillers and stabilizers.
- This composition has many advantages: it is implemented at the usual temperatures of hot-melt adhesives, for example around 180 ° C. ; in addition, it is not necessary, after application, to wait for crosslinking, therefore it is simpler to use than two-component adhesives such as epoxy or polyurethane adhesives for which a hardener is required; more compared to the polyurethane type adhesives which use isocyanates, the use of such a composition eliminates any risk of toxicity as well as the problems of life in pot ("pot life" in English).
- this adhesive composition provides an improvement in the application properties with in particular an increase in the open time and a decrease in the setting time.
- a polyolefin is defined as a homopolymer of an olefin or a copolymer of at least one alpha-olefin and of at least one other copolymerizable monomer; the alpha-olefin advantageously having from 3 to 30 carbon atoms, is for example propylene, 1 -butene, 1 -pentene, 3- methyl-1 -butene, 1-hexene, 4-methyl-1 -pentene, 3-methyl-1-pentene, 1-octene, 1 - decene, 1-dodecene, 1 -tetradecene, 1-hexadecene, 1 -octadecene, 1-eicocene, 1-dococene, 1 -tetracocene, 1 -hexacocene, 1 -octacocene, and 1 -triacontene.
