Definitions
- the invention relates to a ner process for the production of hybrids from polyvinyl chloride and polymers based on conjugated dienes and acrylonitrile.
- ⁇ BR rubbers acrylonitrile and butadiene
- NBR nitrile rubber
- PNC polyvinyl chloride
- the vulcanizates have increased tensile and tear strength.
- the ⁇ BR bale goods are shredded for dry blend ner driving and mixed with PNC powder in batch ner driving.
- the mixture is in the kneader or in the
- the PNC portion is distributed so far in the ⁇ BR phase that no PNC domains can be recognized in the ⁇ BR phase.
- latex blend ner driving the ⁇ BR latex is mixed with a corresponding PNC latex before it is processed into a solid. The mixture is then coagulated, gelled and thus continuously worked up to the solid product.
- a disadvantage of the latex blend ner driving is that the PNC latex used still contains a not inconsiderable amount of monomeric vinyl chloride.
- PNC components For environmental and occupational health and safety reasons (with regard to ninyl chloride see: 1. Hazardous Substances Ordinance, 19th Amendment, 2. Römpp Chemielexikon, Thieme Verlag), it is therefore desirable to use PNC components with a monomeric ninyl chloride content of less than 1 ppm.
- the use of a PVC latex for the production of the blends mentioned is less economical due to the high water content of the latex, which has a disadvantageous effect on the transport and processing (removal of the aqueous phase).
- a disadvantage of the dry blend ner driving is in particular that a homogeneous distribution of the components NBR and PVC used in the blend must be maintained, that the components NBR and PVC must be well distributed before gelling and that the NBR bale goods used must be comminuted well beforehand. All of this is associated with a high technical outlay, so that the dry blend process is less economical than the latex blend process.
- the present invention therefore relates to a method for producing
- powdery polyvinyl chloride in powder form is mixed with the latex based on conjugated dienes and acrylonitrile.
- Powdery polyvinyl chloride according to the invention are homopolymers based on the emulsion or suspension or microsuspension process and graft copolymers and copolymers according to the suspension process with an average particle diameter in the range from 5 to 200 ⁇ m and K values (DIN 53726 or ISO 1628) from 40 to 90 Roger that.
- polyvinyl chloride with the typical residual vinyl chloride content ( ⁇ 1 ppm vinyl chloride) is usually used in the process according to the invention, provided that it satisfies the specification given above.
- latices based on conjugated dienes and acrylonitrile all latices typical of NBR production can be used, which have a polymer weight fraction in the range from 10 to 50%, fractions from 15 to 30% by weight being preferred.
- the amount of conjugated dienes and acrylonitrile in the polymers to be used can vary within wide ranges, for example polymers can be used, the proportion of conjugated dienes in the range from 40 to 90, preferably from 55 to 75% by weight, and their proportion of acrylonitrile are in the range from 10 to 60% by weight, preferably from 25 to 45% by weight.
- 1,3-butadiene and isoprene as well as other conjugated dienes such as 2,3- Dimethyl-l, 3-butadiene, 1,3-pentadiene and piperylene are considered, 1,3-butadiene being preferred.
- acrylonitrile In addition to acrylonitrile, it is also possible to use its known derivatives, such as ⁇ -chloroacrylonitrile and / or methacrylonitrile.
- crosslinking polyfunctional monomers known to the person skilled in the art can be used to construct the polymers to be used. These are especially di- and trifunctional monomers. Examples include divinylbenzene, diethylglycol dimethacrylate and trimethylolpropane trimethyl acrylate.
- the additional monomers for building up the polymers based on the conjugated dienes mentioned and the acrylonitriles can be present in amounts of 0.1 to 40% by weight, preferably 1 to 30% by weight, based on the total polymer.
- latices to be used according to the invention based on conjugated dienes and acrylonitriles, optionally with the addition of the additionally mentioned polymerizable monomers, are described in the specialist literature known to the person skilled in the art, and also their method of preparation (for example Ullmann's Encyclopedia of Industrial Chemistry, Vol. A23, p. A23). 239-364).
- the two components can be mixed in a wide variety of mixing devices.
- mixing devices for example, agitator kettles with variable kettle geometry with single and multi-shaft agitators and different mixing tools as well as rotor-stator mixers, mixing by pumping with and without the use of rotor-stator dispersing machines or mixing nozzles, jet suction devices,
- Injectors tumble mixers, planetary mixers, ploughshare mixers with and without knife stirrers, preferably mixing in agitator tanks or jet suction devices, injectors, guide jet mixers, in particular mixing in agitator tanks.
- the said components are mixed at temperatures in the range from about 10 to 100 ° C., preferably at 15 to 30 ° C.
- the substances and mixtures of substances which are customary for PVC stabilization can be used as stabilizers, organotin compounds, metal soaps, lead compounds and organic nitrogen compounds are preferred, mixtures of calcium and zinc stearate being particularly preferred.
- the stabilizers are usually preferred in amounts of 0.2 to 5% by weight
- the process according to the invention can be carried out by adding the polyvinyl chloride in powder form to the latex based on conjugated dienes and acrylonitrile, with thorough mixing Mixing agitator kettles until a homogeneous mixture of polyvinyl chloride and the polymers mentioned has resulted.
- the suspension obtained in this way is coagulated.
- the known precipitants are added to the suspension in a conventional manner (cf. Ullmann's Encyclopedia of Industrial Chemistry, Vol. A23, pp. 260 to 261).
- a mixture of polyvinyl chloride and the polymers based on conjugated dienes and acrylonitrile in solid form is obtained, which can be further processed in the customary manner to produce all types of vulcanizates, for example for use in hoses.
- Polyvinyl chloride and polymers based on conjugated dienes and acrylonitrile could be produced by simply mixing powdered polyvinyl chloride with the latices mentioned, since it had to be expected that when the PVC powder was stirred into the latex, the latex would coagulate, so that it would not be possible to obtain the desired homogeneous mixture of the two components.
- the analytical determination of the organic chloride content in the blend shows that the PVC powder has been completely coagulated with the NBR latex. There is no PVC loss due to washing processes during the refurbishment process.
