The combined use of fluororubber and ACM has not yet come, and the research on the FPM/ACM combined system has always been a hot spot in the research of fluororubber combined. Acrylic rubber (ACM) has the biggest feature of heat resistance, oil resistance, aging resistance and ozone resistance, good processing performance, and can be used to manufacture sealing products that can be used for a long time at an oil temperature of 150°C. In addition, the price of ACM is lower, and the overall cost is about 10% of FPM. The combined use of the two is designed to produce low-cost products that are resistant to oil and high temperature and can replace FPM in some occasions. It is reported that FPM/ACM combined glue can be made into sealing products with temperature up to 180℃. Research by Zhang Jun et al. showed that in the FPM/ACM blending system with FPM as the main component, either FPM curing system or FPM curing agent-based curing system can be used instead of ACM vulcanization alone. As the vulcanization system of FPM/ACM blends, it may lead to low mechanical properties of the blend, low Shore A hardness, large tensile elongation, long-term deformation at break, and obvious insufficient vulcanization. . In addition, since the cross-linking active groups of ACM and FPM can directly react (or combine), the blending does not require the use of a vulcanizing agent. Basic formula (parts by mass): fluorine rubber F26B 100; light MgO13; calcium hydroxide 4; 3# vulcanizing agent 3; polyethylene wax 2; spray carbon black 10. ACM rubber AR72S100; stearic acid 1; sulfur 1.3; potassium stearate 1.3; sodium stearate 3; spray carbon black 50; N550 carbon black 30; polyethylene wax 3; simethicone 3; anti-scorching agent CTP1. 5; Anti-aging agent ODA 2. Japan GAMEX company developed this kind of blended glue (trade name FAEl23). The heat resistance of the blended rubber meets the F grade of automobile rubber material (ACM is D grade), has excellent weather resistance, low cost, and processing performance is equivalent to general synthetic rubber. MitsuruK-ishine and others later developed a new FPM/ACM blend (AG), and compared it with ACM and FPM compounds. Its heat resistance and compression long-term deformation are better than ACM, and its low temperature resistance is better. FPM, the cost is between the two, and the rubber has good processing performance and process safety. It can be used in fields that require engine oil resistance and cold resistance at the same time as low cost, such as sealing products in the automotive industry or other industrial fields. (O-rings, gaskets, seals, etc.), extruded products (shaft sleeves, hoses) and lift valve seats, diaphragms, rubber rollers, tapes, wire skins, etc. The research results of Zhang Jun and others on this kind of blended rubber also show that the blended rubber has good overall performance and the cost is lower than FPM.

氟橡胶和ACM并用

氟橡胶与ACM并用 迄今未至，对于FPM/ACM并用体系的研究一直是氟橡胶并用胶研究的热点。丙烯酸酯橡胶(ACM)*大特点是具有耐热、耐油、耐老化和耐臭氧性，加工性能好，可以制造在150℃油温下长期使用的密封制品。另外，ACM的价格较低，综合成本约为FPM的10%。两者并用旨在制造耐油、耐高温可在某些场合取代FPM使用的低成本制品。据报道FPM/ACM并用胶可制成温度高达180℃的密封制品。 张军等人研究表明，在以FPM为主组分的FPM/ACM共混体系中，既可采用FPM的硫化体系，也可采用以FPM硫化剂为主的硫化体系，而不宜单独采用ACM硫化剂作为FPM/ACM共混物的硫化体系，否则可能导致共混物力学性能低、邵尔A型硬度低、拉断伸长率大、拉断长久变形偏高，呈现出明显的硫化不足现象。另外，由于ACM与FPM的交联活性基能够直接反应(或结合)，共混也可不需使用硫化剂。 基本配方(质量份)：氟橡胶F26B 100；轻质MgO13；氢氧化钙4；3#硫化剂3；聚乙烯蜡2；喷雾炭黑10。 ACM橡胶AR72S100；硬脂酸1；硫黄1.3；硬脂酸钾1.3；硬脂酸钠3；喷雾炭黑50；N550炭黑30；聚乙烯蜡3；二甲基硅油3；防焦剂CTP1.5；防老剂ODA 2。 日本GAMEX公司开发了这类共混胶(商品名FAEl23)。该共混胶耐热性符合汽车用橡胶材料F级(ACM为D级)，耐候性优良，成本低，加工性能相当于一般合成橡胶。MitsuruK-ishine等之后又开发了新的FPM/ACM共混胶(简称AG)，并与ACM和FPM胶料性能进行了比较，其耐热性和压缩长久变形优于ACM，耐低温性能优于FPM，成本介于两者之间，并且胶料加工性能好，工艺安全，可在要求耐发动机油、耐寒的同时又要求低成本的领域中应用，如汽车工业或其他工业领域中的密封制品(O形圈、垫片、密封件等)、挤出制品(轴套、胶管)及提升阀座、隔膜、胶辊、胶带、电线表皮等。张军等对此类共混胶的研究结果也表明共混胶料具有良好的综合性能且成本低于FPM。
