Definitions
- the invention relates to a modified reaction resin, a process for its preparation and its use for the production of thermosetting plastics.
- Reaction resins are known in the art. These are products that are liquid or plastically deformable prior to processing and result in a polyreaction (in particular polymerization, polycondensation or polyaddition) under generally shaping processing thermosetting plastics. The polyreaction results in a three-dimensionally crosslinked hard and non-fusible resin called a duromer.
- Crosslinked reaction resins generally have good hardness, strength, chemical resistance and temperature resistance. These advantageous properties are due to a generally high crosslink density. Because of these properties, reaction resins are used, for example, for the production of fiber-reinforced plastics, for the production of insulating and casting compounds in electrical engineering, for the production of structural adhesives, laminates, baked enamels and the like. However, the high degree of crosslinking, which leads to the aforementioned advantageous properties, but also causes a number of disadvantages. Duromers are generally brittle and have low fracture and impact strength, especially at low temperatures.
- the object of the invention is to provide a modified reaction resin which, as an as yet uncured precursor, has good storage and processing properties and can be processed into thermosets with good mechanical properties.
- the modified reaction resin according to the invention contains:

- the glass transition temperature Tg is preferably -80 to -120 0 C.
- the two monovalent radicals R which may be identical or different, are linear or branched alkyl groups having 1 to 18 C atoms, cycloaliphatic groups with 4 to 8 C atoms, linear or branched alkenyl groups having 2 to 4 C atoms, phenyl or alkylphenyl groups having 1 to 12 C atoms in the aliphatic radical, where the hydrocarbon radicals are also halogens or hydroxyl, carboxyl, carboxylic anhydride -, amino, epoxy, alkoxy or alkenyloxy groups may be substituted, furthermore lyether- or polyolefin groups and hydrogen, wherein the groups are directly or via an oxygen or nitrogen atom connected to a silicon atom of the polysiloxane chain.
- radicals R are methyl, ethyl, isopropyl, isobutyl, dodecyl and octadecyl groups, cyclopentyl, cyclohexyl and cyclooctyl groups, vinyl, allyl, isopropenyl and 3-butenyl groups, ethylphenyl, Dode - Cyl phenomenon, further groups with hydrocarbon radicals which are partially substituted, for example by halogens, such as fluorine or chlorine, such as the chloropropyl or the 1, 1, 1-trifluoropropyl.
- halogens such as fluorine or chlorine
- radicals R may also consist of polymeric groups, in particular polyethers, such as polyethylene, polypropylene, polybutylene or polyhexamethylene glycol or polytetrahydrofuran, as well as copolymers of these ethers, furthermore polyolefins, e.g. Polybutadiene, polyisoprene, polybutene, polyisobutene and the like. Come into question.
- part of the radicals R can also be hydrogen. It is also possible to use mixtures of the aforementioned polyorganosiloxanes.
- the inventive polyorganosiloxane rubber used is a block copolymer in which monovalent radicals R 'and R "are arranged along the siloxane main chain in blocks which are derived from polymer units of the general formula
- radicals R 'and R' ' which have the same meaning as R, are different from one another, while the radicals R' or R "may be identical or different among themselves, and x and y are 1 or integer Multiples of it are.
- An inventive modified reaction resin is characterized by a high storage stability.
- the dispersion of the finely divided Polyorganosiloxanteilchen in the cyana tester remains surprisingly stable over longer storage periods.
- the polyorganosiloxane particles are preferably already essentially crosslinked to form a rubbery polyorganosiloxane, while a crosslinking reaction of the cyanate ester has not taken place or only to a small extent.
- the dispersed polyorganosiloxane particles can react with the cyanate ester by means of reactive groups arranged on their surface, if this is brought to react or cure.
- a reaction resin according to the invention preferably contains from 40 to 98% by weight, more preferably from 50 to 98% by weight, of cyanoester. Also preferred is a content of 2 to 60% by weight, more preferably 2 to 50% by weight of polyorganosiloxane.
- preferred concentrations are 2 to 10 wt .-%, more preferably 4 to 8 wt .-%.
- the polyorganosiloxane is finely divided in the reaction resin.
- the dispersed particles preferably have an average diameter of 0.01 to 50 ⁇ m, more preferably 0.05 to 20 ⁇ m, more preferably 0.1 to 5 ⁇ m.
- the fine distribution of the liquid polyorganosiloxanes in the liquid reaction resins can be effected with all measures and auxiliaries known for the preparation of emulsions. These include in particular mechanical aggregates which exhibit a sufficiently high shear in the medium to be dispersed, such as, for example, stirrers, dissolvers, kneaders, roller mills, high-pressure homogenizers, ultrasonic homogenizers and the like. like.
- Dispersing devices of the type "Ultra-Turrax" are suitable for achieving a fine distribution. It is understood that the shear forces to be applied to achieve a particular distribution are dependent on the viscosities of the polysiloxane and the reaction resin or reaction resin mixture.
- dispersants compounds having an amphiphilic structure are used, wherein a part of the groups of such amphiphilic molecules is selected so as to be compatible with the polyorganosiloxanes used, while another part of the groups is selected to be compatible with the reaction resin or reaction resin mixture is.
- the suitable dispersants accordingly have a certain emulsifier analogous amphiphilic structure.
- Particularly well-proven and therefore preferred are dispersants co-polymers having a Polyorganosiloxanteil and a kohlenstofforganischen part, which is compatible with the reaction resin or reaction resin mixture used.
- the preparation of such copolymers is known in principle and, for example in W. NoIl, "Chemistry and Technology of Silicones", Weinheim 1968, described in detail.
- the dispersants suitable for the purpose of the invention are not critical to their molecular weight, i. the molecular weight can vary within wide limits.
- dispersants are used which have an average molecular weight of 300 to 50,000. It is essential in any case that the chosen dispersing agent be present under the conditions of the dispersing process at the phase boundary between polyorganosiloxane and reaction resin.
- the required concentration of dispersant depends largely on its effectiveness, the chemical constitution of the polysiloxanes and reaction resins and the dispersing conditions. In practice, good effects are achieved with concentrations of 2 to 20% by weight, preferably 5 to 15% by weight.
- polyether-polydimethylsiloxane copolymers Particularly preferred in the context of the invention are polyether-polydimethylsiloxane copolymers.
- the polydimethylsiloxane content of these copolymers is preferably about 25% by weight.
- the preferred weight ratio of ethylene and propylene oxide units in the polyether is about 40 to 60.
- a preferred molecular weight range is 10,000 to 15,000 g / mol, more preferably about 13,000 g / mol.
- the viscosity at 25 ° C. is preferably 2,000 to 4,000 mPas.
- copolymers are capable of emulsifying polysiloxanes in cyanate esters. and such emulsions or dispersions are stable in storage for a long time.
- the average molecular weight of the liquid, uncrosslinked polyorganosiloxanes which can be used in the process according to the invention can vary within wide limits and is generally in the range from 800 to 500,000.
- the lower limit is determined by that, as the molecular weight decreases, the crosslink density of the polyorganosiloxane rubber increases, thereby decreasing its elasticity. However, this effect can be mitigated by adding bifunctional crosslinking agents within certain limits.
- the upper limit is given by the increasing molecular weight viscosity of the polyorganosiloxanes, which complicates the desired fine distribution of the siloxanes in the liquid reaction resins.
- the uncrosslinked polyorganosiloxane or polyorganosiloxane mixture used has an average molecular weight in the range from 1,000 to 100,000, particularly preferably from 1,200 to
- polystyrene resin 30,000, up. It should be noted that the polyorganosiloxanes as well as most other polymers have no uniform molecular weights, but a more or less broad molecular weight distribution.
- crosslinking by which the liquid polyorganosiloxanes are converted into elastic silicone rubber particles, is irrelevant, as long as it is ensured that the crosslinking reaction does not substantially disturb the fine distribution of the polysiloxane particles and that no or only negligible crosslinking reactions take place in the reaction resin phase. If these requirements are fulfilled, all can usually be networked hardening processes used by polysiloxane elastomers, in particular the known addition and condensation processes. Addition-crosslinking polysiloxanes are preferred.
- the crosslinkable polyorganosiloxane is a vinyl-terminated polydimethylsiloxane to which 1 to 10% of a polymethylhydrogensiloxane has been added as crosslinker.
- the addition crosslinking preferably takes place at room temperature, if appropriate also at elevated temperatures, for example between 60 and 140 ° C., in the presence of a noble metal catalyst.
- compounds of the platinum group elements of the Periodic Table are normally used, for example platinum, palladium or rhodium.
- a frequently used catalyst is, for example, hexachloroplatinic acid, dissolved in suitable solvents, for example in glycol ether or isopropanol.
- suitable catalysts are also the reaction products of noble metal chlorides with organic or organosilicon compounds containing vinyl groups or the noble metals themselves in finely divided form on suitable supports such as activated carbon or aluminum oxide.
- Condensation-crosslinking siloxanes have readily attached to silicon bound easily cleavable radicals, such as hydroxyl, alkoxy, acyloxy, ketoximino, amine, aminoxy or Alkyla- mid groups or hydrogen. These cleavable radicals can be arranged in the polyorganosiloxanes themselves and / or in specially added as crosslinkers silanes.
- condensation-crosslinking polysiloxane elastomers consist of polydimethylsiloxanes having hydroxyl end groups and tri- or tetraorganooxysilanes added as crosslinkers, such as methyltriacetoxysilane, tetraethoxysilane, methyltris (methylethylketoximino) silane or polymethylhydrogensiloxane.
- condensation catalysts is not absolutely necessary in this case, but may be recommended if the duration of the crosslinking reaction is to be shortened or the temperature required for crosslinking is to be reduced.
- Suitable catalysts are first and foremost organic heavy metal salts, such as the known octoates, laurates, naphthenates or acetates of tin, zirconium, lead and titanium.
- crosslinking methods which are known for the preparation of siloxane elastomers, can be extended by those linking reactions which can bring about the three-dimensional crosslinking of the linear polyorganosiloxane molecules.
- the reactive groups required for such linking reactions can not only, as described above for the known cases of addition and condensation crosslinking, sit directly on the polysiloxane main chain, but also with the organic radicals R, R 'or R "of the ortho group. ben specified formulas (1) and (2) be connected or be identical to the functional groups described above, with which these radicals may be substituted.
- the type of linkage per se is not decisive, but any type of linkage is suitable in which essentially three-dimensionally crosslinked polyorganosiloxanes are formed,
- their crosslinking density is low enough to impart elastomeric and non-resinous properties to the crosslinked product, but on the other hand is sufficiently high enough for the crosslinked product to have a minimum of elastomeric properties.
- the average particle size of the polyorganosiloxane rubber particles and their size distribution exert an influence on the essential properties of the cured modified reaction resin, in particular on its fracture and impact strength. It is therefore advantageous for achieving the desired success according to the invention that the particle sizes in the o.g. preferred ranges, with a better effect being obtained if, instead of a very narrow ("unimodal"), a broad distribution of particle sizes, e.g. over the entire particularly preferred range of 0.1 to 5 microns, is present.
- the particle size distribution may, for example, be characterized by a continuous diameter distribution curve in the manner of a Gaussian distribution curve, but it may also be composed of two or three size classes each having a narrower size distribution ("bi- or trimodal").
- the desired particle size distribution of the crosslinked polyorganosiloxane rubber particles present in the reaction resin matrix can already be predetermined and controlled within the limits of the dispersion process during the formation of the uncrosslinked organosiloxane droplets by the selection of the shear forces and, if appropriate, of the dispersant become. Care should be taken to ensure that the particle size distribution obtained during dispersion in the subsequent process steps, especially when crosslinking the polyorganosiloxanes and curing the reaction resins, remains substantially unchanged. But it is also possible and does not affect the invention sought success or hardly, if a part of the particles formed during dispersing in the subsequent process steps coagulates or agglomerates, ie, connects to particles with a larger diameter. This usually results in particles of different size classes, which may, for example, come to the above-mentioned bi- or trimodal size distribution.
- the finely divided polysiloxane rubber particles to chemically bond with the reaction resin.
- the bonding is advantageously effected by a chemical reaction between reactive groups present on the surface of the rubber particles and corresponding reactive groups present in the reaction resin, the reactive groups present on the surface of the polysiloxane particles being matched to the reactive groups of the particular cyanate ester.
- the reactive groups must be on the surface of the polyorganosiloxane autobody particles.
- the radicals R, R 'or R "contained in the polyorganosiloxane have correspondingly reactive substituents, as already explained above by way of example. It is preferred that these substituents are the crosslinking tion reaction of polyorganosiloxanes do not affect in an undesirable manner.
- Another possibility consists in the corresponding, at least partial substitution of the dispersants optionally used in the dispersion process of the polyorganosiloxanes with the desired or required reactive groups.
- this can be realized particularly simply by the fact that care is taken in the selection of a suitable amphiphilic dispersant that its carbon organic constituent has suitable reactive groups.
- a dispersant having a carbon organic part is used, which has reactive groups which can cause chemical bonds between the Polyorganosiloxanteilchen and the reaction resin or reaction resin mixture as reaction mediator.
- reaction mediators Another possibility results from the use of additives which serve as reaction mediators.
- a reaction agent In order to ensure the desired chemical anchoring of the silicone rubber particles to the resin matrix, such a reaction agent must additionally also have chemical groups that bind it to the silicone rubber particles.
- organoalkyloxysilanes and / or organosilicone copolymers having reactive groups matched to the polyorganosiloxanes and cyanate esters.
- Suitable organoalkyloxysilanes are, for example, vinyltrimethoxysilane, glycidyloxypropyltrimethoxysilane, aminopiropyltriethoxysilane, methacryloyloxypropyltrimethoxysilane and the like. like.
- Organo-silicone copolymers suitable for this purpose may be similar in principle be constructed as the dispersants described above. Examples of suitable organosilicone copolymers are condensation products of low molecular weight silanol-terminated polydimethylsiloxanes with diglycidyl ethers, hydroxycarboxylic acids or hydroxyl- and carboxylic acid-containing polyesters, aromatic polyhydroxy compounds, etc.
- reaction with which the polyorganosiloxane rubber particles are to be chemically bound to the reaction resin matrix is expediently carried out before or during the further processing of the modified reaction resin, the nature and conditions of the reaction being largely dependent on the nature of the reactants involved. In the simplest case, a corresponding increase in temperature is sufficient to effect the desired reaction.
- a component capable of reacting with the reactive groups of the polysiloxane particles for example the above-mentioned reaction promoter, or component catalyzing this reaction into the reaction resin.
- the added reaction component or the catalytically active component may be identical to the corresponding components which cause the curing reaction of the reaction resin.
- the chemical bonding reaction is preferably carried out only when the reaction resin after the shaping process is to be cured, optionally simultaneously with this curing.
- the invention further provides a process for the preparation of a modified reaction resin according to the invention, which is defined in claims 18 to 21.
- the aspects of this process have already been discussed above in connection with the discussion of the properties of the reaction resin.
- the polyorganosiloxane can first be dispersed in the cyanate ester or a part of the cyanoester and then a crosslinker for the polysiloxane can be added.
- a crosslinker for the polysiloxane can be added.
- the crosslinking of the already dispersed polysiloxane particles begins to form a polysiloxane gum.
