Abstract

The invention discloses a nylon composite material and a preparation method thereof. The nylon composite material comprises the following components, by mass, 20-90% of nylon 66, 3-20% of high impact polystyrene, 5-50% of an inorganic filler, 0.1-3% of a chain extender, 0.1-1% of an antioxidant, 0.1-1% of a coupling agent, 0.2-3% of a lubricant, and 0.5-3% of functional assistants. The recycled nylon 66 which is adopted as a main raw material allows a case of changing wastes into valuables and the resource recycle to be realized; the high impact polystyrene which is used as a compatilizer allows the comprehensive performance and the impact toughness of the material to be improved, and balanced physical and mechanical properties to be obtained; and the adopted chain extender allows the molecular weight and the relative viscosity of nylon to be effectively improved, and an abuse of the decrease of the physical and mechanical properties caused by the molecular chain rupture in the nylon regeneration process to be effectively prevented. The preparation method which is a one-step method has the advantages of simple production technology and low processing cost.

Description

technical field [0001] The invention relates to recycling of waste plastics, in particular to a high-performance alloy material prepared by recycling nylon 66 and a preparation method thereof. Background technique [0002] my country's plastic output in 2010 was nearly 45 million tons, and it is expected to reach more than 50 million tons in 2011. With the increasing use of plastics, the number of plastic products eliminated every year will also increase. It is a big waste and seriously pollutes the environment. It is estimated that in 2011, my country's recycled plastics are expected to exceed 10 million tons, and the recovery rate is only 20%, which is still far behind the 50% recovery rate in developed countries. Especially in the packaging material market, a large amount of waste packaging films are produced every year. Among them, nylon 66 (PA66), which has a large output, has poor compatibility and low recycling rate. It is usually disposed of by landfill and incine...
