Definitions
- the invention relates to a composite molding containing at least one polyarylene sulfide and at least one elastomer.
- Polyarylene sulfides have a continuous operating temperature of up to 240 ° C. Polyarylene sulfides are flame-resistant and resistant to oxidation. Polyarylene sulfides are extremely hard and rigid. The absorption of water is low. The creep is low even at elevated temperatures. Due to the properties mentioned above, polyarylene sulfides are particularly suitable for the production of moldings with good mechanical properties and thermal stability. Polaraylene sulfides are characterized by chemical and heat resistance as well as rigidity.
- the high surface hardness of molded parts made of polyarylene sulfides and the low sliding friction coefficient of polyarylene sulfides can cause objects lying on top to slip and limit the operational safety of switching elements and operating elements made of polyarylene sulfides.
- seals and damping elements are provided separately and are usually mechanically anchored in an additional work step, which causes additional work and considerable additional costs.
- EP-A-0 326 712 describes improved adhesion to various plastics by means of a mixture or a reaction product from (a) a silicon-free one Compound with at least one alcoholic OH group and at least one alkylene group and (b) an organosilane with at least one alkoxy group and at least one epoxy group, but relatively long reaction times (1 h) at a temperature of 120 ° C are necessary. The long reaction times are often caused by simultaneously inhibiting adhesive additives.
- the inhibition by such additives can only be improved to a limited extent by the choice of an optimized SiH / SiVi ratio.
- Adhesion to aluminum as a substrate is only improved after a relatively long vulcanization time of 2 h (measured at 100 ° C). A possible shortening of the reaction times by increasing the temperature cannot be carried out, in particular in the case of many plastic substrates, because of the lack of temperature resistance.
- EP-A-0 493 791 describes the use of known adhesion promoters together with a tetravalent zirconium compound in order to achieve a bond between silicone rubber and PPS.
- a molded part made from a combination of polyacetal and directly molded functional elements is known.
- the functional elements consist of one or more elastomers, which contain partially or completely hydrogenated nitrile rubbers, one- and multi-component silicone rubbers or sulfur-containing rubbers.
- EP-A-0 875 536 discloses addition-crosslinking silicone rubbers and a process for the production of composite molded parts. PA and PBT are used as substrates. Usually in the production of composite molded parts between a technical polymer such as polyarylene sulfide and an elastomer
- Polymer either by surface treatment with primers or by
- the object of the present invention is to provide a composite molded part made of polyarylene sulfide with a silicone elastomer without complex pretreatment of the polyarylene sulfide during production, the adhesive strength between polyarylene sulfide and the silicone elastomer being improved.
- the object is achieved by a composite molded part containing at least one polyarylene sulfide and at least one one- or more-component silicone rubber, as described in EP-A-0 875 536 or US Pat. No. 5,998,515.
- Polyarylene sulfides can be prepared via dihalogenated aromatic compounds.
- Preferred dihalogenated aromatic compounds are p-dichlorobenzene, m-dichlorobenzene, 2,5-dichlorotoluene, p-dibromobenzene, 1,4-dichloronaphthalene, 1-methoxy-2,5-dichlorobenzene, 4,4'-dichlorobiphenyl, 3,5- Dichlorobenzoic acid, 4,4'-dichlorodiphenyl ether, 4,4'-dichlodiphenyl sulfone, 4,4'-dichlorodiphenyl sulfoxide and 4,4'-dichlorodiphenyl ketone.
- the polyarylene sulfide is obtained as described in EP-A-0 259 984 in a two-stage polymerization process for prepolymerization and main polymerization, a dihalogenated aromatic compound being polymerized with an alkali metal sulfide in an aprotic organic polar solvent to give polyarylene sulfide.
- polyphenylene sulfide is preferably used as the polyarylene sulfide for the production of composite molded parts.
- Polyphenylene sulfide (PPS) is a linear partially crystalline polymer with the general formula: where n> 1.
- housings are also made from polyphenylene sulfide.
- Polyphenylene sulfides have a low mechanical damping factor, which in some applications requires the use of soft damping elements.
- a seal is often required at connection points.
- silicone rubbers such as those described in EP-A-0 875 536 or US Pat. No. 5,998,515, have very good adhesive strength to the polyphenylene sulfide of the molded part, without the polyphenylene sulfide being adhesive-modified or after injection molding is pretreated.
- Addition-crosslinking mixtures which have at least one hydrogen siloxane with at least 2 SiH groups and an alkoxysilane or alkoxysiloxane with at least one epoxy group and optionally a peroxide have good adhesion to substrates and low reactivity.
- the mixture can be processed without a variety of additional components.
- Addition-crosslinking silicone rubber mixtures contain a) 100 parts of at least one alkenyl group-containing linear or branched organopolysiloxane with at least 2 alkenyl groups with a viscosity of 0.01 to 30,000 Pas, b) at least one hydrogen siloxane with at least 2 SiH functions per molecule in an amount so that the molar ratio of the SiH group to the total amount of Si-bonded alkenyl groups is at least 1.5, c) at least one Pt or Rh catalyst and optionally an inhibitor, d) 0.1 to 10 parts of at least one alkoxysilane with at least one epoxy group and / or alkoxysiloxane at least one epoxy group or silanes as described in EP 902059, US 3730932 and US 5998515, and optionally e) 0 to 200, preferably 5 to 200 parts of at least one, optionally surface-modified filler and optionally f) further auxiliaries, such as phenyl silicone oils for self-lub
- organopolysiloxane (a) encompasses all polysiloxanes previously used in crosslinkable organopolysiloxane compositions.
- (A) is preferably a siloxane composed of units of the general formula (I)
- R 1 is a monovalent aliphatic radical having 1 to 8 carbon atoms, preferably methyl
- R 2 is an akenyl radical having 2 to 8 carbon atoms, preferably vinyl
- a 0, 1, 2 or 3
- b 0, 1 or 2
- the sum a + b 0, 1, 2 or 3, with the proviso that on average there are at least two radicals R 2 per molecule.
- dimethylvinylsiloxane is stopped.
- Organopolysiloxanes (a) preferably have viscosities from 0.01 to 200 Pas, very particularly preferably from 0.2 to 200 Pas. The viscosities are determined according to DIN 53 019 at 20 ° C.
