Continuous mixing of elastomeric compounds

An elastomer masterbatch or a compounded productive elastomer stock is made using a twin screw extruder to mix elastomer components in multiple mixing zones at controlled temperatures. Elastomer and other ingredients are fed into the twin screw extruder continuously through precise loss-in-weight or volumetric feeders. The degradation temperature and/or cross linking temperature of the elastomer determines the rate at which the elastomer can be processed, since friction created during mixing heats the elastomer. Accordingly, the maximum rate of compounding is a function of the torque limit, cooling efficiency, and conveying capacity of the extruder. The conveying capacity and torque limit are also a function of the size of the extruder. The viscosity of the elastomer compound in the extruder, as measured by a Mooney viscosimeter (ASTM D1646), is typically in the range of about 20 to 250 units (ML(1+4)100C).

Method for the preparation of a poly(arylene ether)-polyolefin composition, and composition prepared thereby

A poly(arylene ether)-polyolefin composition is prepared by melt-blending a poly(arylene ether), a poly(alkenyl aromatic) resin, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and an unhydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene to form a first blend, and melt-blending the first blend and a polyolefin and additional hydrogenated block copolymer to form a second blend. A reinforcing filler and/or an ethylene/alpha-olefin elastomeric copolymer may, optionally, be added during formation of the second blend or in an additional step. Multiple mixing elements, low throughput, and high extruder rotations per minute may be used to achieve high energy mixing of the first and second blends. Compositions prepared by the method exhibit an improved balance of impact strength, stiffness, and heat resistance, as well as reduced variability of physical properties.

Extruder with integrated die plate and method for degasing polymer mixtures

본 발명은 배럴 (24), 생성물을 운송하기 위해 배럴 (24) 내부에 배열된 하나 또는 여러 개의 압출기 요소 (12,14), 특히 하나 또는 여러 개의 압출기 스크류 및/또는 혼련기 요소 (14), 임의로, 배럴 (24)에 스트리핑제를 공급하기 위한 유입구 포트 및 생성물로부터 휘발성 화합물 및 적용가능한 경우, 스트리핑제를 제거하기 위한 유출구 포트를 포함하는, 특히, 합성 고무 생성물 압출을 위한 압출기 (10)에 관한 것이다. 본 발명에 따르면, 천공된 다이 플레이트 (26)는 유출구 포트 앞에서 흐름 방향으로 배럴 (24)에 고정된다. 다이 플레이트 (26)가 압출기 요소 (12,14)에 고정되는 것이 아니라 배럴 (24)에 고정되기 때문에, 다이 플레이트 (26)와 배럴 (24) 사이에 주변 간극 형성이 방지됨으로써 압출된 물질이 다이 플레이트 (26) 밖으로 방사형으로 통과하지 않는다. 낮은 표면적 대 부피 비를 포함하는 압출된 물질의 부분의 형성이 방지됨으로써 휘발성 화합물의 증발이 촉진된다. The invention relates to a barrel (24), one or more extruder elements (12, 14), in particular one or more extruder screws and / or kneader elements (14) arranged inside a barrel (24) Optionally an inlet port for feeding the stripper to the barrel 24 and an outlet port for removing the volatile compounds and, if applicable, the stripping agent from the product, in particular an extruder 10 for extruding a synthetic rubber product . According to the present invention, the perforated die plate 26 is fixed to the barrel 24 in the flow direction before the outlet port. Since the die plate 26 is fixed to the barrel 24 rather than fixed to the extruder elements 12 and 14, the formation of a peripheral gap between the die plate 26 and the barrel 24 is prevented, And does not radiate out of the plate 26. The formation of a portion of the extruded material including a low surface area to volume ratio is prevented, thereby promoting evaporation of the volatile compound.

Method for extruding polymer blend resin

The present invention provides a method for extruding polymer blend resin which is capable of satisfying performances which are necessary as a resin-coated metal can even when the resin-coated metal can is produced through an extremely stringent working such as drawing, deep drawing, bend-elongation by drawing, stretching or ironing. After feeding thermoplastic resin A to a biaxial extruder through a first raw material feed port of the extruder, the thermoplastic resin A is plasticized in a molten state and is subjected to degassing under reduced pressure. Thereafter, thermoplastic resin B whose melting temperature or softening temperature is lower than a melting temperature or a softening temperature of the thermoplastic resin A is fed to the extruder through a second raw material feed port. Assuming Lb as a length of a blending zone and D as a screw diameter of the extruder, the thermoplastic resin B is blended with the thermoplastic resin A in the blending zone of Lb/D=0.5 to 5.0 and the blend resin is extruded from the extruder.
