Abstract: The invention provides a silane/filler preparation, consisting of from 5 to 70% by weight of at least one silane corresponding to the following formula in which X is a halogen atom, p is 1 or 2, m is 1 to 5, R1 is a C1-C5-alkyl group, C5-C8-cycloalkyl group or a phenyl group, R is a C1-C5-alkyi group, a C5-C8-cycloalkyl group, a phenyl group or a benzyl group and n is 0, 1 or 2, and respectively balanced to 100% from 95 to 30% by weight of at least one inorganic filler. The invention also provides a process for the production of a silane/filler preparation which comprises introducing at least one carbon black and/or at least one silicate filler in powder form into a powder m ?xer in a quantity of from 95 to 30% by weight, after which at least one liquid silane as defined above is address in a quantity of from 5 to 70% by weight, respectively balanced to 100% relative to the filler, followed by brief intensive mixing until a powder-form or granular free-flowing preparation is formed. The preparation is used in optionally crosslinkable polymeric moulding compositions or vulcanisable or cross-linkable rubber moulding compositions such as sulphur-vulcanisable moulding compositions based on natural rubber and/or synthetic rubber.

Abstract: The preparation according to the invention comprises resorcinol and at least one carbon black in homogeneous distribution. The preparation is preferably in the form of beads or granulates. The preferred granular form is attained when the resorcinol has an average particle size of 0.10 to 0.40 mm or is reduced to this average particle size during the production process. Furnace blacks having a specific particle surface area of approximately 40 to 120 square metres per gram, an average primary particle size of 20 to 45 nm and a dibutyl phthalate absorption of 45 to 130 millilitres per 100 grams are preferred as carbon blacks. The preparation according to the invention preferably has a weight ratio of carbon black to resorcin between 70 to 30 and 30 to 70. The upper limit of this weight ratio is 95 to 5. The process for producing the resorcinfiller preparation is also disclosed. Preferably two process steps are carried out namely a) first a treatment of the resorcinol which is in form of the usual platelets or small lumps, jointly with the powdered carbon black in a high speed mixer for several seconds and b) then preferably in another low-speed mixer while the product formed assumes a bead-like shape if the above condition of average particle size of the resorcinol is maintained. The resorcinol can also be applied in the molden form. For the use of the liquid resorcinol the high speed mixer has a heating device and, when required a cooling device, as well as a propeller type or a rough mixing tool. The use of the preparation of rubber adhesion mixtures for improving the adhesion of rubber vulcanizates on metal, textiles or glass fibre structures is also disclosed.

Abstract: 1468853 Carbon black-filled thermoplastics DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 12 June 1974 [29 June 1973] 26031/74 Heading C3P Carbon black is incorporated in a thermoplastics material by a process which comprises adding the carbon black to the thermoplastics material in a continuous screw extruder at at least two points lying one behind the other in the delivery direction. Plastics material and part of the carbon black may be introduced together at a first inlet, and the distance between inlets may be 2 to 6, preferably 3 to 5 times the diameter of the kneader screw. The process may be used to produce concentrates which may be diluted with further plastics material. Examples describe the preparation of compositions of carbon black with (1 to 4) polyethylene, (2) polypropylene and (3) polystyrene.

Abstract: The present invention provides a process for producing furnace blacks having varying structures according to conventional furnace black technology. In order to attain high yields and large throughputs of furnace black raw material, a low ratio between combustion air and furnace black raw material is used and to lower the furnace black structure the furnace black formed is entirely or partially removed from the flue gases. The residual gas thus obtained is entirely or partially recycled to the combustion chamber of the reactor.
