Definitions
- the invention relates to heat-pumpable, thermosetting compositions based on ethylene-vinyl acetate copolymers (EVA), their use as sealing compositions or relining adhesive, and a method for sealing seams in vehicle construction and a method for relining sandwich components in vehicle construction.
- EVA ethylene-vinyl acetate copolymers
- Plastisols These plastisols can be PVC plastisols, as described for example in DE-A-1769325 or DE-A-2200022, but they are also
- (meth) acrylate plastisols as are mentioned, for example, in DE-A-2454235 or DE-A-3523480.
- the plastisols based on styrene copolymers which are described in DE-A-4034725 and DE-A-
- pre-gelling must be carried out by briefly applying a very high temperature, so that the metal parts are very high in the short term
- sealants and sealants based on rubbers which are applied warm. After cooling to ambient temperature, these agents have such a high intrinsic viscosity that they are laundry-resistant a few minutes after application.
- Warmly applicable rubber compositions are used a great deal in body-in-white in automotive manufacturing as adhesives, sealants and sealants.
- These compositions contain rubbers, in particular vulcanizable rubbers based on 1,4-polybutadienes and / or 1,4-polyisoprenes. These compositions preferably contain low molecular weight liquid polydienes, sulfur and optionally accelerators for sulfur vulcanization.
- these compositions can contain high molecular weight, so-called solid rubber, both the liquid polydienes and also the solid rubber functional groups such as hydroxyl groups, carboxyl groups. Can contain anhydride groups or epoxy groups.
- solid rubber both the liquid polydienes and also the solid rubber functional groups such as hydroxyl groups, carboxyl groups.
- EP-A-97394, EP-A-309903, EP- A-309904, DE-A-3834818, DE-A-4120502, DE-A-4122849 and EP-A-356715 are the subject of a number of patent applications, examples of which are EP-A-97394, EP-A-309903, EP- A-309904, DE-A-3834818, DE-A-4120502, DE-A-4122849 and EP-A-356715.
- these rubber compositions have a sticky surface before curing in the paint drying ovens and are very easily deformable by mechanical pressure.
- EP-A-181441 describes a two-component system consisting of a hydroxy-functional 1,3-polybutadiene and a second component based on a polymer 1,3-butadiene exists and contains lateral succinic anhydride groups.
- EP-A-356715 describes a two-component system consisting of a polymer A which contains at least 2 hydroxyl groups per macromolecule and a second component which is compatible with component A and which contains on average at least 2 carboxyl groups or carboxylic anhydride groups per molecule.
- the final strength is achieved by an additional built-in sulfur vulcanization system during vulcanization in the paint drying ovens. Sufficient pressure and grip resistance is only achieved with these two-component systems about 30 minutes after application of the material. This means that the corresponding components can only be processed about 30 minutes after the material has been applied.
- two-component systems in particular such highly viscous systems, require complex metering and mixing apparatuses in order to be able to guarantee reasonably reliable process reliability.
- Hot melt adhesive compositions according to the conventional art would, thanks to their rapid strength build-up after cooling, enable rapid pressure and grip resistance of such a seal, but these hot melt adhesives have two decisive disadvantages:
- thermoplastic character Because of their thermoplastic character, they soften and flow at the temperature of the paint drying oven, so that they would flow out of the seam area.
- the object was therefore to provide heat-pumpable, heat-curing compositions which can be applied directly to the uncleaned sheet metal surface in the car body construction phase and which, when used as a sealant, have sufficient pressure and grip resistance very shortly after the material has been applied, so that the corresponding components can be processed immediately.
- these sealants should have a non-stick surface so that no dust or dirt can stick to them.
- a tack-free surface of these sealants ensures that plant and machine parts in which such sealed automotive components are processed are not contaminated by these sealants.
- the binder system should be such that the hardening or crosslinking of the sealant can take place even at the wide temperature ranges that occur when the electrocoat is stoved in automobile manufacture.
- the hardened sealants have an appealing smooth surface, since these seams are often in the field of vision. For reasons of corrosion protection, no pores or open bubbles may occur. Furthermore, these surfaces must be capable of being repainted using the common lacquers used in automobile production.
- thermosetting compositions which contain at least one solid ethylene-vinyl acetate copolymer (EVA copolymer) Softening point above 50 ° C, measured according to the Ring & Ball method according to ASTM D28, contain at least one liquid reactive plasticizer with olefinically unsaturated double bonds and at least one peroxidic crosslinking agent.
- EVA copolymer solid ethylene-vinyl acetate copolymer
- plasticizers in peroxide-containing ethylene-vinyl acetate copolymer compositions is known in principle, but the manufacturers of EVA copolymers point out that only extremely saturated products are suitable for this, since they have no influence on the peroxide vulcanization. According to the manufacturer, paraffinic mineral oils with very low unsaturation (olefinic double bonds) are primarily suitable as plasticizers. Furthermore, adipate and sebacate plasticizers such as e.g. Benzyl octyl adipate (Adimoll BO) and alkyl sulphonic acid ester of phenol (Mesamoll).
- Adimoll BO Benzyl octyl adipate
- Mesamoll alkyl sulphonic acid ester of phenol
- the sealants of the invention contain EVA copolymers which are solid at room temperature, i.e. they must have a softening point above 50 ° C, this softening point being measured according to the Ring & Ball method in accordance with ASTM D28.
- the EVA copolymers are used in the sealants according to the invention in amounts of 4 to 40% by weight, preferably 7 to 33% by weight of copolymer.
- heat pumpable is to be understood to mean that the sealants have a sufficiently low viscosity at temperatures between 60 ° C. and 110 ° C., preferably between 70 ° C. and 100 ° C., so that they can be used with the usual pumps, conveying devices and application devices can be processed.
- Liquid rubber can be selected from the following group of homo- and / or copolymers as liquid reactive plasticizers with olefinically unsaturated double bonds:
- Polybutadienes in particular 1,4-, 1,3- and 1,2-polybutadiene, polyisoprenes, styrene-butadiene copolymers, butadiene-acrylonitrile copolymers, preferably at least some of these polymers having terminal and / or (statistically distributed) pendant functional groups can have small groups. Examples of such functional groups are hydroxyl, carboxyl, carboxylic anhydride, epoxy or amino groups.
- the molecular weight of these liquid diene homo- and / or copolymers is typically below 20,000, preferably between 1,000 and 10,000.
- the liquid rubbers are contained in the compositions according to the invention in amounts of 5 to 40% by weight, preferably 14 to 35% by weight.
- the rheology of the overall composition is influenced to a high degree by the ratio of liquid rubbers to EVA copolymers, so that the flow behavior of the compositions can be adjusted within wide limits by the corresponding ratio. As a result, both extrudable and sprayable sealing compounds can be produced.
- other compounds with olefinically unsaturated double bonds can also be used, these include in particular the high-boiling (meth) acrylic esters, in particular pentyl (meth) acrylate, isoamyl (meth) acrylate, hexyl (meth) acrylate.
- (Meth) acrylates with more than one double bond per molecule e.g.

- the fillers can also be partially replaced by hollow plastic microspheres, whereby these hollow microspheres can either be used in the pre-expanded form or in the compact form, which only expand in the paint drying oven during curing of the sealing agent. Such hollow microspheres are disclosed, for example, in EP-A-586541 or US-A-4829094.
