The present invention relates to novel and improved resin composites' and, more particularly, to improved processability An elastomer resin having a high amount of ruthenium added. It is also disclosed to make such novel and improved elastomeric composites. The present invention is further directed to elastomeric resins having improved flame retardancy. (2) Prior art manufacturing of elastomer composites such as those used in sealing materials, gaskets, tires, cables, and other articles made from rubber, such as enamel, plasticizer, antioxidant, curing agent, etc. Everything is known. All of these composite ingredients are used to obtain certain properties of the final article or are desirable at the time of manufacture. However, some of these substances do interact with each other, resulting in adverse effects on physical properties or processing behavior. Functional chelates (such as certain carbon blacks and precipitated vermiculite) are used to improve hardness, tensile strength, tear resistance and other desirable properties, but they are especially added in sorghum fillings. The amount of the composite also increases the viscosity of the composite, resulting in poor processability and coking safety. This must be balanced by using plasticizers and/or processing aids. However, plasticizers and processing aids have a negative impact on physical properties, including fire resistance, and they have "blooming". Until now, it has not been known that any material is capable of overcoming the processing difficulty of an elastomer resin composite having a high amount of ruthenium added, and still maintains the physical properties desired. It is very difficult to provide a precise definition of "high strontium filling amount" because it is highly dependent on the polymer used and the application of the final composite. !3〇61〇3 However, 'in general, if the filler 3 of a highly-filled elastomer composite is added, the viscosity will increase until the workability of the composite will be strongly reduced. degree. Therefore, the amount of the filler in the highly filled resin depends on the polymer, which may vary from about i 5 to about 50,000% by weight of the resin. It is known to use micro vermiculite as a semi-reinforcing agent in the elastomer to replace, for example, MT (medium thermal cracking) carbon black or calcium silicate. In these examples, micro vermiculite has been used as a substitute to obtain an elastomer of the same strength and less cost. Therefore, when micro vermiculite is used as a semi-reinforcing agent, the total amount of the chelating agent is never increased. (III) SUMMARY OF THE INVENTION An object of the present invention is to provide a highly filled elastomer composite having low viscosity to provide excellent processability, but without reducing the amount of sputum and without adversely affecting the elastomer composite Physical properties. In some instances, the amount of sputum may even be increased, but does not increase the viscosity and does not negatively affect the physical properties. A further object is to provide an elastomer composite having improved flame retardancy. According to one feature of the invention, there is provided an elastomer composite having a high sputum content. The elastomer composite is characterized in that it additionally contains from 1 to 400% of micrometeorite (by weight of the resin). As a modifier to improve processability. According to a preferred embodiment, the elastomeric composite contains from 5 to 300% of vermiculite (based on the weight of the resin). The preferred elastomeric composite contains from 10 to 15% by mole of vermiculite (with resin 130^3⁄4 9 ; I '.. B..: another feature according to the invention relates to a manufacturing having a high charge A method of highly enriched elastomeric compound in a dosage form, characterized in that the amount of micro vermiculite added to the elastomeric compound is from 1 to 4% by weight (based on the weight of the resin) to improve processability. In a preferred embodiment of the invention, the amount of micro vermiculite added to the elastomeric compound is from 5 to 30,000 (based on the weight of the resin). For best results, the micro vermiculite is added to the elastomer. The amount of the compound is from 10 to 150% by weight of the resin. The term "micrometeorite" as used in the specification and the scope of the application of the present application is an amorphous si 0 obtained from a specific process. 2, wherein the chopped stone (quartz) is reduced to SiO-gas, and the reduced product is oxidized in the gas phase to form an amorphous vermiculite. The micro-sand may contain at least 70% by weight of vermiculite (3丨02) 'And the specific density is 2.1-2.3£/(:1113' and the surface area is 15-4〇1112/£. The particles are substantially spherical and have an average particle diameter of about 0.15 μm. The micro vermiculite is preferably obtained as a co-product in the production of sand or a sand alloy in an electric reduction furnace. Micro vermiculite. Micro vermiculite is recovered by a conventional method using a bag filter or other collecting device. The present invention also relates to the use of micro vermiculite as a modifier to improve the processability of an elastomer compound' and regarding the use of micrometeorites. To improve the ultimate oxygen consumption index of a flame retardant elastomer compound filled with aluminum trihydrate and/or magnesium hydroxide. It has been surprisingly found that the elastomer compound according to the present invention has the same Compared with the elastomer compound which does not contain micro vermiculite, it has low viscosity and excellent processing properties. It has been further found that an elastomer compound having a high cerium content added to micro vermiculite can be used 1306103. All types of cross-linking technology, and it does not reduce the rate of cross-linking in sulfur hardening compounds like other niobium-containing materials (such as precipitated vermiculite) For elastomer compounds containing other vermiculite type chelating agents and decane coupling agents, the amount of decane required for coupling purposes is not increased. In addition to the amount of the agent added, the present invention also saves the processing cost of the other compound ingredients and the elastomer compound which is desired to have better fluidity. In addition, the compression set property of the highly filled elastomer compound can also be improved. Surprisingly, it has been found that the addition of micro vermiculite to these elastomeric compounds results in an increase in the ultimate oxygen consumption index (LO 1 ) in flame retardant elastomer compounds filled with dihydrate and/or chlorine oxide. And when the elastomer compound is filled with aluminum trihydrate and/or magnesium hydroxide, the elastomeric compound forms a stable charcoal when burned. The elastomeric compound according to the present invention comprises an elastomer based substrate such as natural rubber (NR), ethylene-propylene-diene rubber (EPM and EPDM), styrene-butadiene rubber (SBR), acrylonitrile-butyl Diene rubber (NBR), polychloroprene resin (PCP), special polymers such as acrylate rubber and ethylene vinyl acetate copolymer, etc., and blends thereof, and also include elastomers and thermoplastics. Compounds are matrix-based compounds, also known as thermoplastic elastomers, and a process for making such polymer compositions. The term "elastomer" is intended to include not only conventional elastomeric materials such as natural rubber or synthetic rubbery polymers, but also blends thereof with thermoplastic elastomers. The elastomeric compound can be made by using conventional processes and equipment such as open mills, all types of internal mixers and continuous single screw or 1306103 twin screw extruders. The elastomer composite containing the modifier can be prepared by using conventional methods including, but not limited to, extrusion, compression molding, injection molding, and the like. (IV) Embodiments Example 1 Adding 30 parts (phr) of micrometeorite (based on 1 part resin) to an EPDM-based formulation containing 140 phr of calcined clay together with antioxidants, plasticizers and Peroxide hardening system. The mixing of the composites was carried out in an internal mixer, and the samples used for the test were pressure-cured at 180 °C for 20 minutes. The results obtained are shown in Table 1. For the purpose of comparison, the EPDM rubber containing no vermiculite was tested in the same manner as the composite according to the present invention. The test was carried out according to the following specifications: Tensile test: S2 DIN 5 3504, tear resistance (pants tear) BS 6469.

The mixing of the composites was carried out as described in Example 1. The test piece used for the physical test was pressure-cured at 180 °C for 15 minutes. As can be seen from the results in Table 2, it has been surprisingly found that the replacement of precipitated vermiculite with micro vermiculite reduces the viscosity of the composite' resulting in better processability' while maintaining high levels of physical properties.

Example 4 The NBR/PVC composite is filled with a mixture containing carbon black N550, calcium carbonate and precipitated vermiculite, and the total chelating agent content is 1 1 0 Ph. This composite was modified by the addition of 20 phr of micro vermiculite. This mixing was carried out as described in Example 1. The test piece was pressure cured at 180 ° C for a period of 15 minutes. The results obtained are shown in Table 4. 11 1306103 Table 4 Measurement Properties Prior Art The present invention NBR7PVC contains 28 phr precipitated vermiculite NBR/PVC containing 20 phr precipitated vermiculite and 20 phr micrometeorite Mona viscosity (@120 °〇58 42 tensile Strength (MPa) 12.1 13.4 Elongation at break (%) 350 377 Tear property (N/min) 5.8 4.7 Oil resistance 24 hours @100 〇C of ASIM-oil No. 2 Medium tensile strength (MPa) 13.1 13.9 Elongation at break (%) 307 321 The results shown in Table 4: According to The NBR/P VC composite of the present invention has a lower viscosity than prior art composites, although it contains more than 12 phr of a chelating agent. The results regarding oil resistance further demonstrate that when the NBR/PVC composite containing micro vermiculite is subjected to oil at elevated temperatures, the composite maintains its tensile strength and elongation. Example 5 50 phr of micrometium was added to a composite of natural rubber (SIR 20) and was charged with 50 phr of carbon black (N234) and 50 phr of micrometeorite. For the purpose of comparison, a composite containing 100 phr of N234 (Comparative Example 1) and 50 phr of N234 + 50 phr precipitated stone (precipitated vermiculite) was also prepared. Mixing was carried out in an internal mixer using a two-stage cycle similar to that of Example 1. The composite containing vermiculite and decane was mixed as in Example 3 using a standard three-stage procedure. The test piece was subjected to pressure curing at 15 ° C for 15 minutes.

What is done in the above-exemplified examples is not an optimized compound formulation. This means that further improvements in properties are possible when additional reconditioning formulations are completed. The above Examples 1 to 5 show the addition of microfeathers. The stone to a highly filled compound can improve the physical properties of the material while maintaining or even reducing the viscosity of the compound. Example 6 This example illustrates the fire resistance of an elastomer resin composition added to micro vermiculite. Effect: 30 phr of micro vermiculite to ethylene-vinyl acetate-based (100 phr) and filled with 60 phr of aluminum trihalide in a halogen-free, flame retardant compound. The mechanical properties of the compound are not affected. The ultimate oxygen consumption index measured according to ASTM D2863 is from 38 to 43%. The stability of the protective coke formed during the combustion of the polymer matrix is significantly improved, and it is resistant to three without the addition of micro-sand. Up to four times longer. -13-
