Abstract

The invention relates to a chemical corrosion resistant high impact long carbon chain nylon master batch, which contains long carbon chain nylon, compatible toughening agents and heat stabilizers. The invention further relates to a preparation method and an application of the nylon master batch. The nylon master batch has good impact resistance, chemical corrosion resistance and low humidity absorption, and is good in compatibility with other engineering plastics and capable of improving chemical corrosion resistance, low-temperature impact resistance and dimensional stabilities of composite materials, wherein the chemical corrosion resistance includes corrosion from zinc halide, calcium halide and ethylene glycol.

Description

technical field [0001] The invention relates to a chemical-corrosion-resistant high-impact long-carbon-chain nylon masterbatch, a preparation method and application thereof. [0002] Background technique [0003] Nylon, also known as polyamide resin (PA), contains strong polar amide groups in its molecular structure. There are strong hydrogen bonds in its structure, which makes nylon have a high melting point and has good mechanical properties and wear resistance. and self-lubrication. Nylon with different carbon chain lengths has different properties. Generally, the longer the carbon chain, the higher the toughness and impact resistance. [0004] Long carbon chain nylon mainly includes nylon 610, nylon 1010, nylon 12, nylon 11, nylon 612, nylon 1212, nylon 1012, nylon 1313 and nylon 1414. Long carbon chain nylon has low water absorption and thus good dimensional stability. Long carbon chain nylon is more resistant to organic solvents (such as ethylene glycol solution) a...
