Abstract

A method is proposed for producing recycled rubber which involves mixing crumb from used vehicle tires with a devulcanizing agent containing a carbon-chain rubber and Altax (MBTS) until the rubber scrap is completely devuclanized in terms of the intramolecular sulphur bonds, wherein zinc stearate is added to the devulcanizing agent to make up 25% thereof before the devulcanizing agent is mixed with the crumb, next a sheet is produced from the devulcanized mixture and cut into plates of equal mass and area which are arranged evenly over the length and breadth of a roller feed belt and then rolled into 1 mm thick sheets as rubber crumb with a 5:95 ratio of devulcanizing agent to crumb is added to the surface of the sheet by means of a dosing device, after which the resulting sheet is passed several more times through the rollers, the sheet being folded at least in half after each pass through the rollers. This makes it possible to reduce the cost of producing recyclate and to improve the physical and mechanical characteristics thereof by 25-30% over the best of the known prior art.

Description

Reerleader composition at twenty! a process for the preparation of gneisses of regenerated base slurry as a regenerated base slag, a process for the production of gneisses of the re-moving tempo-alphabetized regeaeras;

BACKGROUND OF THE INVENTION The present invention relates to a cellulose concentrate and to a process for the preparation of a recyclizing composition, and to a vulcanized reclaimed gum digestate made from a recycled recycled composition.

The invention relates to the production of a quality product made from rubber waste, in particular sulfur vulcanized used tires, according to the invention.

A light 20 tires per year are produced every year. Of this, only 5 million tonnes are utilized: graniorleméuy is incinerated at power stations and cement mills, while rubber powder is used as an additive in the production of new rubber mixtures with particles smaller than 200 micrometers. The remaining .15 million tonnes of waste are dumped. Almost 20 million used tires are thrown away every year. Only 25% of this is processed into useful products, the rest is disposed of in the trash.

According to the state of the art, the need for recycling is as old as the appearance of tires. I haven't succeeded in producing rubber blends that are perfect for djr making new gmtaroafones. At present, the used rubber is utilized in the manufacturing process as follows: in the meantime, its particles smaller than 2nm are mixed with gypsum additives.

Used gmo rubbers and other rubber products cause environmental contamination. There is therefore a need for a regeneration process that addresses the growing environmental problems. The gtmdabrooes used are highly flammable. Many attempts have been made to mitigate this environmental hazard. Among these are surfaces made of shredded tires for road pavement. or burning such shredded rubber to develop energy.

Attempts to regenerate rubber by mechanical and chemical means are constantly evolving and there are results that have produced a regenerated product with a tensile strength close to that of the tire. The recovery of rubber properties depends not only on the composition of the recycle composition, but also on the particle size. also.

Conventional rubber processing involves crushing the vulcanized rubber, then mixing the crushed rubber with a catalyst and exposing the resulting mixture to a temperature above 170 * € for at least 4 hours in a digester. The resulting material is then masked and then formed into a sheet. The resulting gm products are used in small amounts as processing aids or diluents in the manufacture of fresh rubber products. The presence of reclaimed rubber in the blend adversely affects the physical and dynamic properties of the final vulcanized product.

The Hungarian patent document BU 226481 B (published on 2J07, 8/28) describes mebanochemical air-stabilized and additives gnmibitnmenposposites. The composition consists of a base bitumen binder, a rubber braid and a dispersant, an anti-settling agent, a cross-linking olefinic double bond, a viscosity modifier, and, if necessary, other additional antioxidant * cosmicidal components,

In the process according to the Hungarian patent document HU 181103 B (published on 8/8/1982), a mixture of 60-88 Irish sturmn-butadiene hams, 20-48 Irish 1,4-ss-polybutadiene hens and natural hams is homogenized and at least 388% · and not more than 450% of additives, based on the total weight of the mixture, namely 15-30% active soda ash, 218-338% dolomite, limestone or kaolin: powder or mixture thereof, 28-50% plasticizer, derived from mineral oil and optionally comprised of 5% to 15% crude glycine or pine resin, 2% to 15% emk oxide activator, 2% to 20% pigment, 1.5% to 1.9% sulfur, and 4% to 6% dibromodilyldisulph and give an accelerated mixture of diylguanidine,

CCCP 1016282 (published May 7, 1983) discloses a process for recycling rubber waste, which comprises mixing the rubber with a re-crystallization composition containing 50 percent of a solution of orthophosphate in Hair. The product obtained can not be used as a blend for the production of gnmycarbonate and is therefore used as an additive in

Rli 2014339 (published April 15, 1994, 15feP) discloses a mixture containing 2memaptobenzotbiazole, umrropim, iron steam and glycol as a re-release composition. The product processed using the re-reclamation composition has a tensile strength of 7.6 MPa. However, this value, among other low physical and mechanical parameters, does not allow it to be used as a stand-alone mixture for the preparation of factory formulations,

Rü 2121484 (published November 16, 1998) is a Russian patent for the recycling of rubber sulfenamide, zinc oxide, stearic acid, resin, and grain peroxide. The vulcanization system and the agglomerate are mixed using special mixing equipment. The size of the rubber powder granules is 9-1.5 mm. The disadvantage of the process is that the re-crystallization compounding compound is of high value and must be added to the powder at 39%. In addition, the processed products have a tensile strength of 7-8 Mt. Due to the organic peroside, the individual components must be added to the mixing apparatus (coil, rollers) in a specific order and the technological parameters (temperatures and processing times) must be strictly observed.

A disadvantage of the prior art solutions is that the gummy needle material gene is used in existing compositions and thus only vulcanized rubber with weaker physical parameters can be produced than the originally available physical properties, to produce a tensile elongation of 15 MP & better than 340% and a Shore A hardness of 60-64 Shore A. The Nasodite is mixed with a suitable medium and vulcanized with the finished product to yield tubers close to their original yields.

It is understood that the waste gourmet material is mechanically and chemically regenerated and then a new product is produced so that the rubber properties thus produced reach the properties of the original rubber. However composition reeiklizáló composition of the present invention changed into lÖ% in any component (or the total combined amount of components) - resulted in a deterioration in - the physical and mechanical properties of the product 7 ~ 15 ^e, respectively. It has been discovered that the use of zinc stearaph in combination with lhax (MBTS) with the aid of a novel "diagonal" type of rock formation during devulcanization forms a transient complex in the web, and this complex formation facilitates the disintegration and / or formation of new cyanide crosslinks. Thus, the most general embodiment of the invention is the simplest and cheapest re-activating cone (desulcanizer composition of 4.5 Irish altax (MBTS) + 1.5 tr clips 4 2.2 Irish zinc spearate). Advantageous embodiments of the invention are described, The process for using the re-activating concentrate is described in its most basic form in Claim 7. The properties of the reclaimed gamma regenerated gamma waste product are generally described in Claim 7.

Used gutmabroues mills contain a composition modifier for reclamation of reclaimed base material for reclamation. The mpyracyclary 2 writes one or more of one or more derivatives, preferably one of the derivatives of the henzazole, the buramate, the mercapioofoenzriazole, and the one or the mixture of thiocarbamate derivatives, 1, 5 to 4.0 fir! optionally containing stearate and ca. 1.5 to 4.5 Irish long-chained caucas. In one preferred embodiment, the modifier composition is a 2.5 - S tr accelerator, 1.5 - 4.0 tr barrel, preferably stearate, and Contains 1J - 4.5 tr natural kanesuk. Optionally, the modifier composition is 4.5 Irish accelerators 2.2 ri slider! and 1.5 Irish natural mares, most preferably sliding grease containing 2.2 tr of cis-starch, 4.5 tr of 2.2 '' dibenzothiazole disulfide (MBTS) 1.5 g of natural pellicle (SZKl-3), regenerated rubber In the process of applying a re-activating modril crater composition in the manufacture of a vuikanisate, the Irish used rubber mill, 3 to 15 parts by weight of an Irish accelerator, 1 to 4 tr of slip, preferably zinc stearate and 5 to 3 tr of natural caustic succin, and We mix 5 Irish natural hides and cure at 15 ° C. The rubber obtained by this process has tensile strengths of 8 to 35 Mba, elongation at 239 to 359 5s, elastic modulus of 5 to 8 MPa, and hardness of 55 to 65 Sh A.

The bite of this recycle lies in the fact that it is an active inmolecular complex between altot (MBTS) and eink stearate, which is actually an accelerator in the recycling of rubber waste and subsequent volcanization of the processed product. 4 polysulfide linkages have relatively low energy (5,000 kPa / mole) and, therefore, at higher vulcanization temperatures, they are relatively easy to decompose and form an elastomer. The formation of diagonal bonds and the formation of new chemical bonds are activated by zinc stearate. These and other objects are accomplished by a composition comprising an accelerating component and a natural clamp of a re-activating component alt (MBTS), comprising: administering einearearate according to the present invention to a mixture of 4.5 tr alt (MBTS) 1.5 Irish rubber 2.2 tr zinc stearate. In this way, using the new component, other chemical bonds are formed with the other components and a higher tensile strength rubber is obtained.

The proposed re-acylating composition is characterized by simplicity and low-grade nausea, which is to be added at a 5% rate for devulcarization relative to the amount of ore, with a ratio of 1, 5 to 5 times daesonyabh for all other sulfur.

Λ

The gum tire used in the process is admixed with a re-acidizing composition prepared using canine, aitax (MSTS) and cinfc stearate. The devulcanized mixture is then made into a plate which is cut into parts of uniform weight and size, then laid evenly along the length and width of the shaft dispenser and made into a sheet of 1 mm thickness, with the aid of a dispenser 'etómrlemeuy in a ratio of 5:95. Subsequently, the plate thus produced is passed through the rollers a few more times while being bent at least twice after each roll.

We have tried to recycle the gwlhnílaöékck, a quality wider ash (including aafeahrnesnk), for your love of the cegenerátótn received! qualities are approximate (to obtain buck and mechanical vulcanizates. Therefore, we have developed a re-vulcanization and / or re-vulcanization process with a re-occlusive component. The elaborated process had to meet the inexpensive raw material, the simple and environmentally friendly and excellent volatility.

Since 95 percent of the rubber grades, including tire gums, we have sought a method of cross-linking to create a new net after breaking the net.

I'm modifying A.FC ~ 10! resulting in a mixture having a diphortic moment, the tensile strength of which depends on the strength and / or the number of complex bonds between the molecules. The modification affects the processing stages of the vulcanized rubber or the processing of the recycled rubber gum product.

When the vulcanized gtma breaks down its crosslinking bonds, the APC-18 modifier prevents the breakdown of the carbon-carbon bonds between the polymeric molecules of the rubber by creating a transient complex bond with the polymeric chains of their canos, a transient bleaching of the crude mixture. With the formation of such a transient complex, the throne is a braided product, merely reducing the sulphidation of the diagonal bonds in the web, while leaving the excimer matrix unchanged. More recent three-dimensional complexes of vulcanization and jdtmefc that link the polymeric chain of the processed product to the accelerating molecules found in the polymer also produce new polysiphenic diagonal bonds with a lower degree of solubility on the active rupture of the crosslink. The operating principle of the ARC-W modafahl cat is shown in Figure 4.

The AFC-10 modifier acts on the rubber shingle not only by restoring the previous sulfide chemical bonds between the polymer chains of their canos, but also by forming new three-dimensional complexes with the shorthand molecule (aitax (MBTS)) and rubber polymer macromolecules. resulting in a complete blend of recycled rubber products.

As a result of our research, we have developed a rubber waste modifier (composition). whose mechanism of action during the processing step is to establish an active transition complex linkage with the polymer chains of their canos upon breaking of the diagonal polysulphide crude bond bonds, and during the volatilization step to form new three-dimensional complexes between MB subunits and polymer chains ( ) accelerator. Meanwhile, the well-known E, N. Sotnikova procedure (Be-Link) only works during the processing phase, facilitating the breaking of s / ulildes bonds, u Proton exchange stimulation on the mediator accelerator group In this way, the developed AFC-W mod kéd'-sulfur breaks the sulfur chemical bonds in the rubber, creating the active transition complex with the radicals formed thereby, which creates a series of secondary diagonal bonds in the vuJcanization process and contributes to the restoration of polystyrid bonds.

smaller threads in degrees. The modifier developed is less expensive, less expensive, smaller in quantity, and most importantly, it gives the physical product better physical properties than zinc stearate. Helps to restore diagonal sulfide bonds but also contributes to the creation of a secondary crosslink during vndkanfe

The properties of the vulcanizates of the present invention were compared with those of known vulcanisers made from gum waste (US 577003232, published on t998, p. 2399). The recycle mixture containing benzothiazole (altax) is mixed with rubber gum fly ash, The gunheel and recycle mixture are cylindrical malotnhan eternal and at the same time are subjected to subsequent crushing of the germ mixture in the mixture.

As shown in the table, the regenerated gomi fully meets all criteria.

Embodiment of the invention; gum ulcer recycle composition, containing altax (MBTS) blend and rubber, differs from the others in that the emk stearate is added to the blend and has the following composition:

Sleep (MBTS) - 4.5hrs:

rubber - 1.5 tr;

emfc stósrate - 2.2 tr.

The recycle composition allows tires and other rubbers to be converted into crude, high-quality gorse debris by breaking the sulfur bonds, which is capable of producing additional polysilidide diagonal bonds in secondary valorisation.

The gunite waste recycling activator is utilized as a blend of the following sulfur drum dr (2-ber5Zthiazobi) -disulphide (MBTSbinc-zinc stearate). During vulcanization, it creates an additional crosslinking network on the accelerated (alias: (MBTS)) basal bond chains. Thus, the new component contributes to the formation of new diagonal bonds between the polymer chains of the canine matrix, which results in recycled rubber. to make a complete blend.

The process is carried out using a tire grinder with a natural granulate composition after grinding on the roll, while being previously cleaned of the textile and metallic fibers. A recycle composition modifier is then prepared from the following ingredients: rubber - 1.5 l, alias (MBTSl - 4.5). Mixed with stearate in a volume of 2.2 tr. Then a slab is prepared from this mixture. cut into parts of equal mass and size, these parts are evenly spaced longitudinally and widthwise at the shaft feeders and made into a sheet having a thickness of 1 ", while simultaneously filling the haogerset with the same amount of rubberized material. passing through the hmger blade a few times and bending it at least twice after each rolling. This is much simpler and one and a half times cheaper than a similar solution for recycle composition. The profitability of the process according to the invention is increased by a higher rate of re-emulsifying composition should be added to the rubber powder (5 percent),

The re-nucleation (devulcanizing) of the named ingredients provides the opportunity to destroy the gunpowder at a sulfur molecular rock level and provides for the restoration of me bonds, as well as providing additional epithelial bonds during the production of vtd products. The methods employed in the method, their sequence and their parameters, allow the rubber crumb to be made into rubber articles having a tensile strength of 15 Wa at 30% and greater elongation and a strength of OM4 Shore. Because of such features, the recycled product can be added to the ahmncmix 80% of the recycled product during the production of the new gmmabmoospk, so that the present invention is sufficient to achieve the intended purpose,

By using an overlay composition containing the named ingredients, the sulfur-crosslinked bonds of the grafting product are disrupted, and these three-dimensional bonds are restored to the existence of the product during the preparation of the products. The processes, sequence and parameters used in the process of this invention allow the production of rubber articles having a tensile strength of 15 MPa and a tensile elongation greater than 34 ° C! and a hardness of between 60 and 64 Shore A. Thanks to these peculiarities, 88 percent of the tendon-agitating product is found to be added to the tire blend when making new rubber bibs,

Example 2:

Production of Recycled Rubber: Mix the used tire powder with a re-lysing composition using canoes and altax (MBTS). Stirring is continued until the rubber waste is completely recycled. This process differs from the others by adding smk-stearate in a 25% amount before mixing with the gummy plate in the re-release composition. Then, the devanlizanate mixture is prepared from a mixture, which is cut into parts of equal weight and dimensions, then laid evenly along the length and width of the shaft feeders and made into a plate of thickness 1 mm, with the aid of a composite body). Subsequently, the plate thus produced is passed through the rollers a few more times, and in the meantime, to a minimum of two times. after each rolling.

In the process of the present invention, the grinding of the used tires is mixed with a deviser made using a hose and akax (MBTS). Stirring is continued until the rubber resin is completely re-activated (i.e., the sulfur bonds are broken).

This process differs from the others in that 25% of Clnk stearate is added to the reconstituting composition prior to mixing with the gum solution. The slab is then made from the devulcanized mixture, cut into portions of mass and size, then laid, uniformly length and width and 1 mm thick, and at the same time filled into the surface with a 5: 95 rupture plate. ). The plate thus produced is then passed through the rollers a few more times while being doubled after each roll.

This allows us to reduce the cost of producing the rubber to be recycled and to improve our physical and mechanical properties by 25-30% compared to the best known solutions,
