Abstract

The invention discloses a flame-retardant nylon 1010 material, which is prepared from the following raw materials in parts by weight: 110 to 130 parts of nylon 1010, 4 to 6 parts of phosphorous acid,0.01 to 0.02 part of a catalyst, 3 to 5 parts of pentaerythritol, 1.6 to 2 parts of epoxypropane, 30 to 40 parts of a diatomite dispersion liquid, 2 to 3 parts of cyanoethyl cellulose, 1 to 2 parts ofcalcium acetylacetonate and 0.1 to 0.2 part of diisopropylethanolamine. According to the invention, the dispersion compatibility between the intercalation filler and the nylon base material is achieved, the mechanical stability of the finished product is further improved, and the composite material is high in flame retardance and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a flame-retardant nylon 1010 material and a preparation method thereof. Background technique [0002] At present, nylon is widely used in machine tools, machinery, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, rail transit, automation control and other industries. In recent years, with the continuous development of high-speed rail, subway, and intelligent machine tools, nylon bellows Higher requirements are required, low temperature resistance requires -50 ℃ ~ -60 ℃, ammonia water, oxalic acid corrosion resistance, higher wear resistance requirements, flame retardant requirements low smoke and halogen-free; [0003] Polymer materials are an important cornerstone of modern industry and high technology, and an important guarantee for the basic industries of the national economy and national security. On the one hand, polyme...
