Problems solved by technology

[0005] The invention can solve the problem that the existing NBR product production and processing device cannot stably extrude the rubber raw material in the molten state from the plastic tube, and cannot ensure that the action of extruding the rubber strip and the action of cutting the rubber strip are carried out at the same time, resulting in rubber The length of the cut strips is different and the production efficiency of the rubber strips is low. It can also solve the problem that the existing rubber production and processing equipment cannot cool the rubber strips after cutting in time and rapidly, resulting in the accumulation of rubber strips. Extruded deformation, cooling water cannot be circulated in time, resulting in poor cooling effect on rubber strips

Abstract

The invention relates to a Buna-N rubber product producing and machining method. A Buna-N rubber product producing and machining device is used in the method, and comprises a bottom plate, an extruding and slitting mechanism and a cooling and shaping mechanism. The method can solve the problems that an existing Buna-N rubber product producing and machining device cannot stably extrude a rubber raw material in a molten state from a molding pipe, it cannot be guaranteed that the rubber strip extruding action and the rubber strip cutting action are conducted at the same time, the cutting lengths of rubber strips are different, and the rubber strip producing and manufacturing efficiency is low; and the method can also solve the problems that due to the fact that the existing Buna-N rubber product producing and machining device cannot rapidly cool the cut rubber strips in time, the rubber strips are stacked together and are pressed and deformed, cooling water cannot be circulated in time, and consequently, the cooling effect on the rubber strips is poor.

Description

technical field [0001] The invention relates to the technical field of nitrile rubber, in particular to a production and processing method of nitrile rubber products. Background technique [0002] Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. . Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil-resistant rubber products. Abbreviated as NBR. Because of its excellent oil resistance and physical and mechanical properties, NBR is widely used in the manufacture of various oil-resistant rubber products, such as O-rings, rings, hoses and fuel tank lining rubber, printing cylinders, oil tank linings, insulating floor boards, Oi...
