Problems solved by technology

However, due to the extremely high molecular weight of UHMWPE, it has almost no flow properties and is extremely difficult to process. The UHMWPE raw materials used for pipeline production are actually ultra-high modified materials after modification. Various types and different amounts of additives make the commercially available UHMWPE pipes far apart in terms of performance and price.

The method comprises the following steps: 1) weighing an ethylene-octylene block copolymer, an ethylene-octylene copolymer, nano silicon dioxide, a dispersing agent, a lubricant and an antioxidant according to parts by weight, adding into a stirrer, and uniformly mixing at normal temperature for 5-8 minutes; 2) transferring the raw material mixture into a double-screw granulator, heating to a molten state, adding dimethyl silicone oil according to parts by weight, uniformly mixing, and carrying out extrusion and granulation to obtain the elastomer alloy material master batch; and 3) putting the obtained elastomer alloy material master batch in an extruder, and carrying out extrusion forming through the extruder to obtain the elastomer alloy material. The elastomer alloy material has the advantages of excellent attrition resistance, favorable flowability, excellent physical and mechanical properties, and high sanitation and safety, is suitable for double-layer or multilayer coextrusion, is free of any toxic or harmful additive, and satisfies the related sanitary standard.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an elastomer alloy material and a preparation method thereof. Background technique [0002] Wear-resistant pipelines are a very important market segment in the pipeline industry. Wear-resistant pipelines are mainly used for conveying pipelines for pneumatic, pumped slurry and other materials. Due to the poor corrosion resistance and wear resistance of steel pipes, the wear-resistant pipeline industry has been seeking new chemical pipelines to meet the requirements for wear resistance. In foreign countries, steel pipes are mainly lined with rubber or polyurethane elastomer (TPU) to produce wear-resistant pipes. The process is more complicated, the process requirements are higher, and the cost is also higher. The bonding strength of the surface must be guaranteed by very strict material selection and process requirements. In the domestic application of this kind of steel-lined ru...
