Abstract

An organic reinforcing and armouring material based on synthetic and natural carbon polymers, with and without functional groups, in particular based on polyalkenyl having tertiary carbon atoms, modified by a content of catalysts, organic and/or inorganic or inorganic-organic silicon (IV) compounds and dry cement powder, has been found which can be incorporated into wet concrete and can be converted into mouldings (shaped articles) and appears to be an organic substitute for asbestos in respect of setting (strength values).

Description

Reinforcement and reinforcement material, processes and

Device for its production and its use.

The present invention is an organic3 reinforcement and synthetic and natural α-polymer based reinforcement material, a method and an apparatus for producing such a material and its use.

The substitution of harmful asbestos fibers in the construction industry in the production of prefabricated parts, panels, beams etc. by harmless organic fibers are becoming more and more urgent.

The main problem with this is that organic fibers are too low as a result Hydrophilic and therefore insufficient wettability when mixed into the concrete matrix tend to clump, i. e. assume an inhomogeneous distribution in the fresh concrete. This problem is exacerbated in the case of polymers without functional groups, such as e.g.

for polymers based on polyalkylene with tertiary carbon atoms in the polymer chain. This is particularly evident in the hydrophobic polypropylene, a technical one significant fiber. While, for example, with hydroxy-substituted polypropylene (CE3 replaced by OH) the 3 polyvinyl alcohol, the presence of functional groups A certain hydrophilicity ensures what most methods peel off in order to by adding bonding agents (e.g. methyl cellulose) to the concrete to produce better wettability due to Van der Waal's bonds. The results However, as practice shows, these efforts are not yet sufficient no real covalent bonds are created from the fiber to the matrix, a corresponding Adhesion strength fiber matrix would have. Also, the previous ones are procedure in relation to the production of large quantities of chemically modified fibers as substitutes not sufficient for asbestos fibers to reinforce a hydraulic matrix such as concrete economically.

The state of the art is a more recent process in DE-OS 2816457 again with organic fibers based on hydrophilic polymer building material mixtures to reinforce or reinforce accordingly, so that stable moldings with Hydraulic binders can be produced by adding hydrophilic fibers of substances such as cationic polyelectrolytes to improve the retention of hydraulic Binders on the fiber (Van der Waals binding) can be used.

The object is therefore particularly afunctional polyalkylene polymers how to modify the surface of polypropylene fibers in such a way that a covalent one Bonds to the matrix. This can be achieved with afunctional polyalkylenes with tertiary carbon atoms in the chain difficult, since these inert systems only under drastic conditions (e.g. oxidizing agents, higher temperatures) under partial Chain splitting react.

A mild process of manufacture a reinforcing material based on polyalkylene with tertiary carbon atoms by reaction of polypropylene with organosilicon chlorides in inert solvents and in the presence of metal soaps as catalysts at room temperature (20C), was described in the DE patent application 3041595 described. A covalent C-Si bond is actually formed here Replacement of the tertiary hydrogen atom by an organosilicon chloride residue.

e.g.

When this organosilicon chloride-modified polypropylene PP is mixed in with wet concrete, two opposing reactions (a) and (b) take place for the reinforcement result: the intra- and intermolecular condensation of the organosilanol groups-SiR2OH formed by water with Si-0-Si bridging the or between the polypropylene organosilanol chains and the intermolecular Si-O-Si bridging (c) between modified polymers and concrete, which is ultimately sought. (a) and (b) cause separating layers between polymer PP and concrete, (c) on the other hand chemical bonds between PP and concrete.

Since the reaction leading to c) is the reaction leading to (a) and (b) slightly outweighs the speed, the result is one with modified fibers reinforced matrix that is stronger (compressive strength, tensile strength, flexural strength) than the corresponding matrix reinforced with unmodified fibers.

The Si-C bond is stable against hydrolytic cleavage with the basic medium of the concrete, while bonds of the carbon polymer with the organosilicon radical via hetero bridging atoms such as O, N, S in the form of polymer - CO-Si-derivative, polymer-C-NE -Si-derivative, polymer-CS - Si-derivative, which are formed by reaction of organosilicon halides, for example with hydrophilic groups on polymers such as polymer-C-OH, polymer-C-NH2, polymer-C-SH, are unstable to hydrolysis and therefore do not bring any significant increase in strength when reinforcing hydraulic systems.

Derivative part: e.g. halogen, hydroxyl, concrete C-Si bond hydrolytic stable in an alkaline environment such as concrete; C-O-Si bond hydrolytically unstable in alkaline environment, ester cleavage in polymer-C-OH and OH-SiR2 derivative or condensation product.

But since the binding of the modified fibers with the matrix is not yet possible is satisfactory (see Experiment 1, Table 1), the task had to be molded with to produce significantly increased strength through a modified, changed Procedure to be resolved.

The task is with an organic reinforcement and reinforcement material based on synthetic and natural carbon polymer according to the invention thereby solved that functional polymers, the afunctional polyalkylenes, both with tertiary Carbon atoms, combinations of these polymers (block or randomly distributed polymers), any mixtures of these polymers (polymers with polymers, combinations with Combinations, polymers with combinations) by a content of catalysts or

Mixed catalysts, organic and / or inorganic-organic and / or inorganic silicon IV mono- and / or polymers and / or combinations of these silicon IV polymers (block or randomly distributed) and / or mixtures these silicon IV compounds and dry cement powder are modified; as well functional polymers without tertiary carbon atoms analogously through a content of the same Silicon IV compounds.

(Combinations and mixtures as above) and dry cement powder, however without catalysts or mixed catalysts; likewise the above polymers with tertiary Atoms through a content of mixed catalysts, electrophilic C-compounds and / or Mixtures of the same and dry cement powder also include the above polymers with tertiary carbon atoms only through a content of mixed catalysts and dry cement powder. Farther is the task by the method of producing such a material and solved by the device.

Those listed in claim 2 can be used as modifying reagents Silicon IV compounds are used, preferably organhalosilanes according to Claim 8.

Tertiary carbon atoms are preferably used as the material to be modified containing synthetic functional e.g.

Polyacrylonitrile, polyacrylic ester, polyvinyl chloride, polystyrene, polyvinyl alcohol, Polyvinyl ester ect. and afunctional polyalkylenes containing tertiary carbon atoms z. B. polypropylene, LD-polyethylene, polypropylene-LD-poly-polyethylene, polypropylene-HD-polyethylene ect. and natural polymers containing tertiary carbon atoms, e.g. rayon, cellulose ect. according to claim 5 eigesetzt.

As a working hypothesis and without restricting the invention to such a hypothesis, it is assumed that in the case of the reaction of a polymer containing tertiary carbon atoms with organosilicon halides, the hydrogen atoms located on tertiary carbon atoms are replaced by organosilicon halide radicals (see 5,15,19) as catalysts act as metal soaps and / or metal soaps / Lewis acids (e.g. Sn-II-Octoate, Zn-II-Octoate / ZnCl2, Sn-II-Octoate / SnCl2).

Part of the EC1 escapes from the system, and part of it reacts with the diorganosilicon chloride-substituted polypropylene, releasing an organic residue (here ethylene).

Surprisingly, the reaction proceeds sufficiently Reaction rate at room temperature under the influence of catalysts or mixed catalysts. This can be z.R '. trace on a polypropylene film, which can be immersed in a solution of methylvinyldichlorosilane and tin dioctate for just a few seconds immersed in the inert solvent e.g. CCl4 or CS2. about the influence of water vapor and exclude oxygen the reaction is carried out on a PP film which is in a cuvette. The cuvette is filled with nitrogen as the inert gas rinsed and the reagent / catalyst solution introduced, after a reaction time of 20 seconds at a reaction temperature of 200 ° C., the catalyst solution is drawn off again and rinsed purge the cuvette with nitrogen to remove any solvent residue. The following IR measurement shows that there are clearly new ones in the IR range 700 to 800 Show bands that cannot be assigned to any of the substances used, but rather only a surface bond formation of PP and methylvinyldichlorosilane under ECl leakage and formation of a silicon-carbon bond C-Si. The new gangs show dichroism even when using oriented foils. This clearly shows the connection formation.

Longer exposure time of the modifying reagent / catalyst solution to PP leads to a higher conversion. The same applies to heating the modifying reagent / catalyst solution. PP fibers can be dipped into this solution or sprayed with it even at room temperature. Subsequent immediate spraying or dusting of the modified reagent / catalyst solution treated fiber with dry cement powder or dry cement powder suspension in an inert solvent (e.g. chlorinated hydrocarbons or CS2) leads to a stable chemical bond of the modified fiber with cement with further formation of Si-O-Si bridges. This organosilicon-cement-modified PP fiber can be mixed into wet concrete without any problems while it sets.

This is in contrast to the mixing in of modifying reagent / catalyst solution sprayed fiber in wet concrete by spraying modifying reagent / catalyst solution sprayed fiber with dry cement powder or dry cement powder suspension (im inert solvent) the opposing reactions (a) and (b), leading to a separating layer between fiber and concrete prevents, reaction (c) occurs on the other hand, as desired, a. The result is an odorless, air-stable, storable, asbestos-like material Fiber that is also elastic and mixes into wet concrete without any problems when it sets leaves.

Also with natural fibers such as cellulose fibers (flax fibers, hemp fibers, Cotton fibers, wood fibers etc.) or O-substituted cellulose fibers (viscose fibers, Xanthate cellulose fibers ect.) Organohalosilanes react under the influence of catalysts (e.g.

Sn-II-octoate) with tertiary atoms of the polymer chain quickly under mild conditions at room temperature (2000) with substitution of the tertiary hydrogen atom by an organosilicon halogen residue. But there is also a reaction with free OH groups with the formation of the corresponding sellulose-O-organosilicon halogen compounds, which, however, in contrast to the cellulose C organosilicon halogen compounds, is strong are sensitive to hydrolysis. Such bonds are made by moisture, especially quickly split again in the alkaline medium of the wet concrete and do not contribute anything Strength of the molded body. In addition, the reaction produces cellulose-O-organosilicon halogen compounds HOl free, the damaging to tissue made of cellulose and substituted cellulose fibers acts if you are not working in the presence of ammonia as a neutralizing agent. Therefore, the treatment of tissues with e.g. trimethylchlorosilane could prove useful Do not enforce textile waterproofing (chemistry and technology of silicones, W. Noll, Verlag Chemie, Weinheim / Bergstrasse 2nd edition, page 506).

According to the invention in the reaction of organochlorosilaneqxmit Fiber material with tertiary atoms and acidified H atoms (e.g. OH, NH, SH groups) the hydrogen chloride released by adding alkaline dry cement powder neutralized.

This makes the fiber odorless and air-stable and easy to mix in ideally suited to a hydraulic matrix (concrete).

Apparently they play a role in the substitution of a tertiary hydrogen atom on the polymer under mild conditions by organosilicon halogen radicals catalysts of the type Metal soap R-COOMe (Me e.g. Zn, Sn, Ca) plays an important role (cf.

on this macromolecules, H.G. Elias, 4th edition, Hühig and Wepf Verlag Basel, Heidelberg, New York, p. 938).

A possible interpretation of the processes would be: Bel in 1) and 2) comes from organochlorosilane by hydrolysis and is practically always present as an impurity. ~~~~ B ,, COnC12 C1- --- rt PP-0-ZnCl + HOOCR -------- Cl- R 80-170 ° C 0 / intermediate grade PP-C-CR2OZnCl R2SiCl2 40-800 l + HOOCR R2Si (OOCR) 2 PP-C-OR2OH In012 + ClZn (OOCR) I 0 rP-C-SiR, Cl 20-80 G .rP-C-SiR2 (OOCR) + ClZn (OOCR) 1) to 5) in inert solvents, e.g. CCl4 For reactions of compounds containing tertiary carbon atoms with modifying reagents according to claim 2 with the exception of the halosilanes and organohalosilanes and modifying reagents according to claim 6 (electrophilic reagents, e.g. carbonylactive compounds), metal toxins are used as a catalyst Lewis acid also needed, so a mixed catalyst.

The reaction of tertiary CH polymers with carbonyl active compounds as a modifying reagent in the presence of a mixed catalyst results in the subsequent Spraying with dry cement powder as opposed to organosilicon halides Modifying reagents do not cause covalent bonds to the modified polymers with dry cement powder but to a functionalized polymer with substitution of tertiary hydrogen, which is used in dry cement powder as well as in wet concrete van der Waals bonds that are naturally weaker than covalent bonds.

The same applies to polymers without tertiary CH groups.

Functionalized polymer is not created here, it just becomes only van der Waals forces between polymer surface and modifying reagent and Formed dry cement powder or wet concrete.

The principle of the reinforced molded body produced today is based only on the exploitation of such van der Waals forces or, to put it another way, adhesive Powers.

Interestingly, fibers containing tertiary CH groups also show modified with a mixed catalyst solution or suspension and coated on top with dry cement powder or a dry cement powder suspension - for solutions or suspensions, inert solvents are used - when mixing into wet concrete compared to the modified fibers or those with only dry cement powder or one such a suspension dusted fiber increased strength values That Application of solutions or suspensions of the modifying reagent and the catalyst or mixed catalyst based on tertiary hydrogen atoms containing synthetic and natural Polymers are made with inert solutions, e.g. Hydrocarbons or non-flammable Halocarbons, ethers, esters by dipping or spraying or provided the modifying reagent is liquid as a modifying reagent with dissolved therein or suspended catalyst or mixed catalyst without solvent.

However, the catalyst or mixed catalyst can also be used first Solution or suspension in inert solvents applied by dipping or spraying and then the reagent as a solution, suspension or if it is liquid is without inert solvent by dipping, spraying or steaming.

Metal soaps such as Mg-II-, Ca-II-, Sr-II-, Ba-II-, Zn-II-, Al-III-, in the form of carboxylates, such as octoate, laureate, palmitate, Oleate, stearate ect., As mixed catalysts, due to the metal soaps and Lewis acids mentioned such as Alel3, ZnCl2, BF3, SbCl5, SnCl2 preferably as catalysts Sn-II-octoate, Zn-II-stearate, Ca-II-stearate, as mixed catalysts Sn-II-octoate / ZnCl2, Zn-II stearate / ZnC12, Sn-II-octoate / SnCl2, Sn-IIoctoat / SbCl5, Ca-II-stearate / ZnCl2 If one is apart from the surface also want to modify the interior of the polymer material - see B. for thicker foils, Granules - the material can be subjected to a longer immersion treatment (e.g. a few hours) and then another heat treatment (e.g. a few minutes Residence time in the extruder at temperatures of 140 to 2000C and above) for production of films or fibers (jet-spun or splice fibers). One uses a Solution of the catalyst or mixed catalyst and the modifying reagent with or without an inert solvent or a corresponding suspension, Cheap as carbonylactite reagents are esters, amides, provided they are liquid, most of them Form a solution with metal soaps and ZnC12 and for spray treatment such as immersion treatment do not require any additional solvent. If any of these three components remains insoluble - even with the addition of an inert solvent - so only one Suspension can be assumed, is the spray or immersion treatment with a Execute suspension, unless an additional addition of acetone or ethyl acetate bring about the solution.

In the case of immersion treatment, however, the additional use of Acetone, ethyl acetate or dimethylformamide with a mixed modification, also in the case of spray treatment with higher-boiling, reactive (carbonyl-active) solvents, but hardly with low-boiling solvents such as acetone and ethyl acetate to be expected.

SbClD can be used particularly favorably for problems of this type, whereby solubility of the components is achieved.

A prolonged exposure to heat after the immersion treatment or if one carries out the modification reaction in an autoclave, also above the melting point of a polymer containing tertiary CH groups such as polypropylene in the case of monofunctional reagents such as ketones and aldehydes via the hydrophilic modification with OH groups out to crosslinking through condensation (water leakage) and thereby to form rubber-like products.

With bifunctional reagents such as functional acid derivatives occurs networking even after a short exposure to heat. But this is the case with surface modifications (Spray treatment or brief immersion) is desirable because crosslinking with formation a free OH group takes place.

Prolonged heating leads to prolonged immersion treatment even here to further crosslinking (condensation of OH groups through water leakage) and Formation of rubbery products.

Both spray and short immersion treatments followed by short ones Heat treatment with mono- and bifunctional modifying reagents leads to not rubbery products, but in the case of isotactic polypropylene to spliceable, surface-modified foils. Cheaper are of course because of the larger surface area continuous fibers or staple fibers, the same applies to trifunctional Organoisocyanates or

-thiocyanate (binding of three polypropylene reaction pathways to hydrophilize polymers containing tertiary carbon atoms with substitution of the hydrogen atoms bonded to them, e.g. in the case of polypropylene, with electrophilic modifying reagents in the presence of metal soaps and Lewis acids as mixed catalysts e.g. Zn (stearate) 2 / ZnCl2.

The addition of mono-, bi-, trifunctional modifying reagents and Mixed catalysts for granules can occur as a result of crosslinking reactions lead to the formation of rubber-like material (elastomers) during extrusion, which initially results in poor spliceability with prolonged temperature-time exposure however, expressed by a complete loss of spliceability (advanced Networking). The film becomes more speckled as a result of temperature-time exposure Rough on the surface, crystallinity and isotacticity, among other things becomes less, the orientation in the subsequent stretching process can no longer fully Scope can be achieved and this causes considerable difficulties when still possible at all, a fibrillation of a still isotactic before the extrusion Carry out polypropylene in fibers.

As a rule, monofunctional reagents are used in the extrusion process Suitable as e.g. ketones, less bifunctional, but also lead to longer periods Temperature-time loads in the extruder lead to poorer splicing properties Cross-linking (condensation with water leakage) so that there is no longer any tendency to splice is.

When observing the above precautions and adding monofunctional or bifunctional modification9-reagents and mixed catalysts occurs however if the dwell time in the extruder is short, there is no substantial crosslinking and the result is good hydrophilic film material that can be spliced into fibers. These fibers are suitable as Reinforcement fibers in a hydraulic matrix.

That. Introduction of catalysts or mixed catalysts with and without modifying reagents based on Si-IV, preferably organosilicon chlorides together with dry cement powder in the extruder or spraying the extrudate after leaving of the extruder with dry cement powder for the production of foils, foamed foils or film-fibrillated or jet-spun fibers according to claims 22 and 23 is an alternative procedure for the surface modification of endless or Staple fibers from superficial application of catalyst modifying reagents or mixed catalyst modifying reagents and dry cement powder according to the Claims 14 to 21, 24 to 27.

Surface treatment of continuous or staple fibers.

Immediately after the spray treatment of the surface of the endless or Staple fibers with catalyst or mixed catalyst / modifying reagents ds. Fig. 1, 2 and 3, claims 14 to 21, 24 to 27) is followed by a spray treatment with dry cement powder or a dry cement powder suspension in an inert solvent on, the solvent sprayed into the air stream being present in excess is condensed in a downstream cooler, the modified staple fibers in a cyclone or on a grate, excess dry cement powder on one Downstream cyclone filter (fabric or electrostatic filter) or downstream of the grate Filter separated and solvents such as dry cement powder fed back into the process will; the same procedure is used for continuous fibers (see Fig. 1).

However, you do not only need the two spray treatments connected in series, but can first be sprayed with a catalyst respectively.

Mixed catalyst / modifying reagent when dry cement powder is switched off run through, possibly react for a certain time on the polymer surface and then in a second pass through the series-connected Device make the dry cement spraying, the spray treatment with There is no catalyst or mixed catalyst / modifying reagent. For the second The staple fiber can pass continuously or discontinuously (i.e. immediately or after a period of time) can be sucked in again from a storage container.

The throughput speed of the continuous fibers can be easily adjusted regulate the motor driving the guide rollers, that of the staple fibers Changing the angular position of the propeller blades (small and large angular positions possibly also opposing individual propellers in horizontal and vertical operation).

For example, the modification of polypropylene-polyethylene copolymer (PP-PE copolymer) and rayon (see Tab. 1 to 12, Diagram 13, 14) and others with the modifying reagents vinylmethyldichlorosilane, dimethyldichlorosilane in inert solvents such as carbon tetrachloride, chloroform and trichloroethane ect.

carried out.

It turned out that the optimal surface coverage of PP-Pe copolymer fibers with the modifying reagent vinyimethyldichlorosilane between 5 and 6%, of cellulose fibers between 8 and 9. PP homopolymer is also found in the range between 5 and 6%.

Mixing in 0.6% unmodified fibers (PP-PE copolymer, see Tab. 12, example 6) and of 0.6% vinylmethyldichlorosilane catalyst-modified fibers (PP-PE copolymer, see Table 12, Examples 4 and 5) in an identical standard concrete mixture after 28 days of curing gives compressive strength of 17.5 N / mm² for PP-PE copolymer fibers unmodified 57 N / mm² for PP-PE copolymer fibers vinylmethyldichlorosilane catalyst-modified Fibers 20 N / mm2 for cellulose fibers unmodified (analogous to above, see Table 12, Example 19) 47 N / mm2 for cellulose fibers, catalyst modified fibers (analogous to above, see Tab. 12, example 24) For data on PP-PE copolymer fibers, see experiment 1 kg. m N = Newtons = sec² Hardening: in a damp room Similar values result for phenylhydrodichlorosilane, Diphenyldichlorosilane, while the values for methylhydrodichlorosilane, dimethyldichlorosilane and methyltrichlosilane are slightly lower.

The influence of the solvent and the fiber covering with dry cement powder seems to be of minor importance as long as the solvent is related is inert to the reactants and there is enough dry cement powder on the fiber. The proportion of fibers in the concrete mix and the proportion of fiber covering with modifying reagent seems to have a decisive influence on the strength values (in our examples the compressive strengths). A fiber content of 0.6% was found, for example as much cheaper than higher proportions of 2.5% (see Table 12). Values from 5 to 6% fiber coverage with vinylmethyldichlorosilane or dimethyldichlorosilane on PP-PE copolymer and 9% vinylmethyldichlorosilane or dimethyldichlorosilane on rayon Maxima of compressive strength in each case when the organosilicon chloride is pre-modified Material indicating hydrolytic cleavage of HCl (Avoidance from the influence of moisture) with dry cement powder. In the attempts of the Tables 1 through 12 are the reaction times of the organosilicon chlorides with the polymers 5 minutes each time; then dry cement powder was sprayed on or the fibers with it Dry cement powder shaken. Conditional to achieve the same compressive strength an increase in the reaction time and reaction temperature a decrease in the proportion the fiber loading with modifying reagent. So by increasing the response time and increasing the reaction temperature beyond 5 minutes or above room temperature (2000), modification reagent can be saved, which is particularly important in the case of inert polymers bearing tertiary C-H groups.

Fiber treated with excess modifying reagent leads to a reduction in the compressive strength values and a sensitivity of the dry cement powder / modifying reagent / catalyst treated fiber against humidity (hydrolysis of a Interlayer of organosilicon halide that is sensitive to hydrolysis and through total hydrolysis a separating layer is formed, which allows the coming about covalent Bonds between polymer and concrete not allowed, see Diagrams 13, 14).

The strength values of the concrete body made with modified polymers and catalysts are modified can still be increased significantly by 1) Increase in reaction time 2) Increase in reaction temperature 3) Use of polymers with a higher C-H proportion (e.g. PP-PE copolymer replaced by PP homopolymer) 4) Homogeneous Distribution of the staple fibers in the concrete 5) Better vibration compaction of the concrete 6) Low water / cement ratio e.g. down to 0.4. In all examples In Tables 1 to 12, a high water / cement ratio of 0.74 el = was set.

7) use of fibers with a higher draw ratio (higher tear strength); In Tables 1 to 14, the stretching ratio 1/14 was used for PP-PE copolymer; With PP, however, a stretching ratio of 1/25 is easily possible.

The concrete body reinforced with modified fibers is set in a closed damp room in air with a certain humidity (e.g. above water at room temperature) or only after 10 days of standing in a damp room and then Stand under water until the end of the 28th day. Previous laying underwater leads to a significant loss of compressive strength, so that the reinforcement with modified Fibers become useless. The fiber-reinforced concrete bodies suck in this case full of water and then only a low compressive strength results. At the The safest way to allow curing to take place is in a damp room.

Examples for the modification of staple fibers and continuous fibers.

Experiment 1 Modification of fibers by dipping in / or spraying with Mo with modification solution. Staple fibers made of PP-PE copolymer (PP isotactic, HDPE content 10%, HD-PE admixture 5%, length 12 mm, diameter 10 - 50, stretching ratio 1/14) produced by fibrillation (splicing) of blown film.

20g dry fibers are dissolved in a solution of 2ml VinMeSiCl2 / 0.1 ml Tin-IIoctoat immersed in 100 ml of chloroform (20 seconds), part of the solution of squeezed or sucked off or centrifuged off the staple fibers (if possible under Moisture exclusion).
