Abstract

The invention relates to a nylon composition for wind-blown sand spinning sand filter and a preparation method thereof. The nylon composition is prepared from the following raw materials by mass ratio: 40-60% of nylon 66 chip, 10-25% of nylon 46 chip, 5-20% of a lubricating agent, 5-15% of a maleic anhydride grafted ethylene elastomer, 5-15% of a reinforced modifier, 1-5% of kaolin, 0.1-0.5% of a compatibilizer, 0.1-1% of an antioxidant and 0.1-1% of white oil. The nylon composition provided by the invention has high strength, excellent high temperature resistance and abrasion resistance; and the prepared blade has excellent warping resistance and dimensional stability, and can effectively guarantee the angle of the sand filter blade.

Description

technical field [0001] The invention relates to a nylon composition used for a wind-sand spin sand filter and a preparation method thereof. Background technique [0002] The blade is the most basic and critical part of the wind-blown sand spin sand filter. Its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the sand filter. Harsh environment and long-term operation put forward the requirements of wear resistance, high temperature resistance and high fatigue strength for the blades, which have a long service life and can withstand the impact of sand and gravel for a long time. [0003] At present, the blades of wind-blown sand spin sand filters are mostly made of alloy materials, which are of high quality, high manufacturing cost and poor dimensional stability. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above-mentioned deficien...
