Definitions
- the invention relates to a hot-melt pressure-sensitive adhesive composition for a releasable connection of two substrates.
- pressure-sensitive adhesives are used to temporarily fix one substrate to another. This type of adhesive enables the substrates to be separated from one another later.
- a typical application example are hygiene insoles in the Feminine Care segment.
- a pressure sensitive adhesive composition When formulating a pressure sensitive adhesive composition, two aspects that are contrary to each other must be taken into account.
- Known pressure sensitive adhesives have a time-dependent adhesive force, i.e. liability increases over time. If the composition is formulated so that the initial adhesive adhesion, i.e. the immediate adhesion allows a displacement-free positioning of the substrate, after some time such an adhesive force develops, which results in undesired adhesive deposits on the other substrate when the substrate is detached. This effect is due to a cohesive break in the adhesive joint.
- the adhesive composition is formulated in such a way that the liability is sufficient, the resulting low immediate liability, i.e. the initial adhesive adhesion problems with slipping.
- US 5,459,193 describes a hot-melt composition for typical pressure-sensitive adhesive formulations in textile and non-woven Area, especially for applications in the Feminine Care segment.
- This composition is based on a styrene block copolymer (SBC).
- SBC styrene block copolymer
- such a composition has the unsatisfactory initial liability mentioned at the beginning. Even if a part or all of the SEBS polymer is replaced by an SIS and / or SBS polymer, the initial adhesion can be increased, but at the same time the cohesion is reduced to such an extent that cohesive breakage occurs in the final adhesion, ie residues occur.
- the hot-melt pressure-sensitive adhesive composition according to the invention contains at least one resin component, at least one styrene block copolymer, a plasticizer component and optionally additives and is characterized in that the composition in addition to the at least one styrene block copolymer is a hydrogenated one Styrene-butadiene-butylene-styrene block copol mer contains.
- a hot-melt pressure-sensitive adhesive composition according to the invention is preferably solvent-free (cf. Römpp Chemie Lexikon, Vol. 3, Georg Thie e Verlag 1990, "Adhesives").
- resin components can be used as resin components.
- resin components are rosin derivatives including wood oil resins, tall oil and their derivatives, rosin ester resins, natural and synthetic terpene resins and aliphatic, aromatic or mixed aliphatic-aromatic hydrocarbon resins.
- Further resin components with aromatic constituents can be produced from monomers each having an aromatic and a polymerizable, unsaturated group. Suitable monomers are, for example, styrene, ⁇ -methylstyrene, vinyltoluene, methoxystyrene, tert.
- Aliphatic monomers are usually natural and synthetic terpenes which contain C 5 or C 6 cyclopentyl or cyclohexyl groups and have a number of aromatic, ring-shaped substituents.
- Other monomers for these tacky resins are 1,3-butadiene, cis-1,3-pentadiene, trans-1,3-pentadiene, 2-methyl-1,3-butadiene, 2-methyl-2-butene, cyclopentadiene, dicyclopentadiene, Terpene, terpene-phenolic resins and others.
- resin components that can be used are coumarin indene resin, phenolic resins, p-tert-butylphenol acetylene resins, phenol-formaldehyde resins, xylene-formaldehyde resins, oligomers of monoolefins or diolefins, aromatic or cycloaliphatic hydrocarbon resins , hydrogenated hydrocarbon resins, hydrocarbon resins, hydrogenated wood oil resins, hydrogenated oil resins and their esters with mono- or polyfunctional alcohols. Hydrocarbon resins, polyterpene resins, rosin resin esters are preferred.
- the resin component is added to the hot-melt pressure-sensitive adhesive composition in a proportion of between 20 and 70% by weight and preferably between 40 and 60% by weight, based on the total weight.
- the varying properties of the resin component used or the mixture of resins have a limited effect on the exact proportion of the resin in the composition.
- the styrene block copolymer is based on an ABA structure, ie styrene sections are provided at the beginning and at the end of the polymer molecule, which include, for example, a B block made of 1,3-butadiene monomers (SBS copolymer). A B block with isoprene monomers is also conceivable.
- the properties of these copolymers can be influenced more or less specifically in the polymerization of these block copolymers.
- Various styrene block copolymers of this type are known to the person skilled in the art and can be specifically selected by the person skilled in the art for the intended area of use.
- plasticizer components allows the physical properties of a composition to be improved, including improved processability, coatability, etc.
- Oil-like plasticizer components are used in the composition according to the invention.
- the plasticizer component is preferably a liquid at room temperature, for example a hydrocarbon oil or polybutene.
- Mineral oils and here mineral oils with a low content of aromatic compounds are particularly preferred (characterized by a carbon distribution of C / A ⁇ 2%, C / N ⁇ 40%, C / P> 60% according to DIN 51378 or ASTM D 2140).
- Other suitable compounds are olefin oligomers, low molecular weight polybutene polymers, vegetable oils and their derivatives and other suitable plasticizer liquids.
- the proportion of this plasticizer component in the pressure-sensitive adhesive composition is between 20 and 40% by weight, preferably 25 to 35% by weight, based on the total mass.
- additives to the composition according to the invention can advantageously have an influence, inter alia, on the stability of the pressure-sensitive adhesive.
- Suitable additives as stabilizers are, for example, sterically hindered phenols, phosphites or thioesters. To a certain extent, these can prevent decomposition reactions caused by atmospheric oxygen or other external influences (eg light radiation).
- the hydrogenated styrene-butadiene-butylene-styrene block copolymer has, in addition to the two terminal styrene block sections, a central block which in turn is composed of butadiene and butylene monomer blocks.
- This butadiene-butylene block is preferably selectively hydrogenated. This modification allows the copolymers to be adapted to certain requirements.
- the ratio of styrene block proportions to the common proportions of olefin block and alkylene block can vary and is between about 20:80 and about 80:20. Ratios between 25:75 and 35:65 and between 60:40 and 75:25 are advantageous: a ratio of about 30:70 is particularly preferred.
- an SBS polymer (Europrene SOL TE 6414, Polimeri Europa) are added 52.3% by weight of hydrocarbon resins (Escorez 5400 40.3% by weight; Escorez 5415 12% by weight, Exxon Mobil) and 30% by weight. of an oil (Shell Catenex PH941, Shell) mixed.
- This Stabilizers (Irganox 1010 and Irganox PS 800, each 0.1% by weight; Ciba) are added to the mixture.
- 7.5% by weight of an SBBS polymer (Tuftec P1000; Asahi Kasei) are further added to the mixture.
- the solvent-free composition has a slightly yellowish, transparent appearance and a softening point of 93 ° C according to DIN 52011.
- the use of the SBBS polymer surprisingly shows that initial and final adhesive values as well as cohesion fully meet the application requirements.
- Examples 2 to 4 were prepared in accordance with the procedure of Example 1; their respective compositions are shown in Table 1.
- Comparative examples VI and V2 the compositions of which are shown in Table 2, were prepared in an analogous manner.
- the hot-melt pressure-sensitive adhesive compositions according to Examples 1 to 4 and the comparative examples were melted as a thin layer onto a PE film (application weight 25 g / m 2 ). Sections of this film were glued to a cotton substrate and removed immediately and after a storage period of 4 hours at 40 ° C., loaded with 36 g / m 2, using a tensile testing machine at a speed of 500 mm / min at a 90 ° angle. Adhesion was assessed in N / 25 mm, and a visual assessment was made of adhesive residues on the cotton substrate.
- Table 3 shows the results obtained Table 3: Measured values of the peel tests on cotton (BW)
- the measured values are given in N / 25mm.
