Abstract

The invention relates to a regenerated MC nylon composite material which is prepared from the following raw materials in percentage by mass: 34.9%-67.3% of regenerated MC nylon resin, 25%-35% of glass fiber, 4%-10% of flexibilizer, 0.2%-0.6% of antioxidant, 0.5%-1.5% of lubricant, 1.0%-3.0% of black master batch, and 7%-15% of anti-wear agent. A preparation method for the regenerated MC nylon composite material comprises the following steps: a step I of drying; a step II of raw material proportioning; a step III of uniformly stirring; a step IV of extruding and pelletizing. According to the regenerated MC nylon composite material provided by the invention, mechanical performances, heat resistance and wear resistance of the regenerated MC nylon composite material are greatly improved by virtue of compounding effect of various functional auxiliaries and special screw combination; at present, the product is successfully applied to conveying pipelines in the industries such as petrol, chemical engineering, metallurgy, mine, and the like. The preparation method is simple in process, high in continuous production efficiency and stable in product quality.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer composite material preparation, and more specifically relates to a regenerated MC nylon composite material and a preparation method thereof. 【Background technique】 [0002] As one of engineering plastics, MC nylon products are "replacing steel with plastic, with excellent performance" and have a wide range of uses. It has many unique properties such as light weight, high strength, self-lubricating, wear-resistant, anti-corrosion, insulation, etc. It is a widely used engineering plastic and is used in almost all industrial fields. However, since MC nylon, as a kind of thermosetting property, will produce a large amount of leftovers during use, how to realize the high value-added recycling of MC nylon resin is a serious problem facing the society. [0003] MC nylon modified materials have achieved the purpose of "replacing steel with plastic" in many fields, which not only reduces the cost of pro...
